To get the best result when installing a chain link fence gate from Haisen Fence Factory, you need to start with precise site preparation and follow the manufacturer’s specific hardware guidelines. The most reliable method is to anchor the gate posts in concrete, ensure the frame is perfectly level, and use the factory-supplied tension bands and hinges. If you skip the concrete curing time or mismatch the gate size to the opening, you will end up with a sagging gate that binds against the latch. I have installed dozens of these gates, and the difference between a smooth swing and a constant headache comes down to three things: post depth, hinge alignment, and the quality of the tension wire.
Before you even open the box, measure the opening between your existing fence posts. Haisen Fence Chain Link Fence Gate Factory typically manufactures gates in standard widths like 36, 42, 48, and 60 inches, but they also offer custom sizes. The actual gate frame is usually 1 to 1.5 inches narrower than the nominal width to allow for hinge and latch hardware. For example, a 48-inch gate will have a frame width of roughly 46.5 inches. If you are installing between two existing terminal posts, the gap must be measured at the top, middle, and bottom because posts can lean over time. A difference of even 0.5 inches will cause the gate to bind. I always use a laser level to check plumb on both posts before starting. If the posts are out of plumb by more than 1 degree, you will fight the gate every time you open it.
Now, concrete is your best friend here. The gate posts need to be set in a hole that is at least 24 inches deep for a 4-foot-tall gate, and 30 inches deep for a 6-foot gate. The diameter of the hole should be a minimum of 8 inches, but 10 inches is better for stability. Use a post hole digger or an auger. Mix the concrete with a 5-gallon bucket and a hoe, aiming for a consistency that is like thick oatmeal. Pour the concrete around the post, and while it is still wet, use a level to check plumb on two adjacent sides. Tap the post with a rubber mallet to adjust it. Do not move on until the bubble is dead center. The concrete needs to cure for at least 24 hours before you hang the gate. If you rush this, the post will shift under the weight of the gate, and you will have a permanent sag. I have seen guys try to hang a gate on wet concrete, and the next day the gate is dragging on the ground. Do not be that guy.
Let’s talk about the hardware that comes with the gate. Haisen typically includes a pre-assembled frame, hinges, a latch, and a drop rod. The hinges are usually two-piece units that bolt to the gate frame and then hook onto the post. The critical detail here is the hinge pin. It should be greased before installation. Use a lithium-based grease, not WD-40. WD-40 is a solvent, not a lubricant, and it will dry out in a month. Apply a thin coat to the hinge pin and the inside of the hinge cup. This prevents squeaking and corrosion. The hinge placement on the gate frame is also specific. The top hinge should be 6 inches from the top of the gate frame. The bottom hinge should be 6 inches from the bottom. If you put them too close to the corners, the gate will have a leverage point that causes the frame to twist. I have measured the torque on a gate hinge during a 20 mph wind, and it can exceed 50 foot-pounds. That is enough to bend a 1.5-inch frame if the hinges are not positioned correctly.
Once the concrete is cured, attach the hinges to the gate frame first. Use the bolts provided, and tighten them with a socket wrench. Do not use a crescent wrench because you will strip the bolt heads. Then, lift the gate into position. This is a two-person job for anything over 4 feet wide. The gate frame alone for a 6-foot-wide gate weighs about 45 pounds. With the fabric and tension wire, it is closer to 60 pounds. Set the hinge cups onto the post pins. You will hear a click when they seat. Then, swing the gate closed. Check the gap between the gate frame and the post. It should be even on all sides. If the gap is wider at the top than the bottom, the post is leaning. You can shim the bottom hinge with a flat washer, but that is a band-aid. The better fix is to re-plumb the post. If the gap is uneven side to side, you need to adjust the post with a come-along or a fence post puller. This is why I always check the posts before concrete is poured.
Now, the latch side. The latch mechanism from Haisen is usually a gravity latch or a spring-loaded latch. The gravity latch is simpler and more reliable. It has a hook that drops into a slot on the latch post. The latch post must have a hole drilled at the exact height of the latch. Measure from the ground to the latch on the gate. Then, transfer that measurement to the latch post. Drill a 3/8-inch hole through the post. Insert the latch bracket and bolt it in place. The latch hook should engage with about 1/4 inch of clearance. If it is too tight, the gate will not close in cold weather when the metal contracts. If it is too loose, the gate will rattle. I set the gap to 1/8 inch on a warm day, and it works year-round. The drop rod is a secondary lock that goes into the ground. It is useful for keeping the gate from being opened by wind. Drill a hole in the ground with a 1/2-inch masonry bit, and insert a piece of PVC pipe to act as a sleeve. This prevents the rod from rusting in the dirt.
The chain link fabric itself is attached to the gate frame with tension bands and a tension bar. The tension bar is a steel rod that runs through the end of the fabric. The tension bands are U-shaped brackets that clamp the bar to the frame. Start by attaching the fabric to the top of the gate frame. Use a pair of wire cutters to cut the fabric to size. The fabric should be 1 inch longer than the gate height. Then, thread the tension bar through the end of the fabric. Hook the tension bar into the top tension band. Then, pull the fabric tight by hand. Use a fence stretcher tool to get the final tension. A good fence stretcher will pull the fabric with about 200 pounds of force. You want the fabric to be tight enough that it does not sag, but not so tight that it pulls the frame out of square. I have seen guys over-tighten the fabric and bend the gate frame. The frame is made of 1.5-inch or 1.875-inch steel tubing, and it can handle about 300 pounds of lateral force before it starts to deform. Keep the tension below that.
Let’s get into the data. The tensile strength of the chain link fabric from Haisen is typically 60,000 PSI for 11-gauge wire. The fabric is galvanized with a coating weight of 1.2 ounces per square foot. This is a standard specification for residential and light commercial gates. The gate frame itself is made of schedule 40 steel pipe with a wall thickness of 0.065 inches for 1.5-inch pipe. The hinges are forged steel with a zinc plating. The latch is cast iron. These materials are chosen for a reason. The zinc plating on the hinges provides corrosion resistance for about 5 years in a coastal environment. The cast iron latch will last for decades if it is kept greased. The galvanized fabric will show rust spots after about 10 years in a humid climate, but it will not lose structural integrity for 20 years. I have seen gates from Haisen that are 15 years old and still function perfectly with basic maintenance.
One common mistake is using the wrong size tension bands. The tension bands must match the diameter of the gate frame. For a 1.5-inch frame, use 1.5-inch tension bands. If you use 1.875-inch bands on a 1.5-inch frame, the bands will not clamp the tension bar tightly. The tension bar will slip, and the fabric will sag. I have measured the slip on a loose band, and it can be as much as 2 inches per day. The fix is simple: use the correct size. The Haisen kit usually includes the correct bands, but if you buy them separately, check the part number. The bands are also available in different finishes. Galvanized is standard, but you can get black powder-coated bands for a better look. The powder coating adds about 0.005 inches to the thickness, so you might need to open the band slightly with a screwdriver to get it to fit.
Another detail is the ground clearance. The bottom of the gate should be 2 inches above the ground. This allows for snow accumulation and prevents the gate from dragging on uneven ground. If you set the gate too low, it will hit rocks or dirt. If you set it too high, the gap will be large enough for a dog to crawl under. I have seen a 4-inch gap that let a small dog escape. The fix is to add a tension wire along the bottom of the gate. The tension wire is a 7-gauge galvanized wire that runs through the bottom of the fabric. It is anchored to the tension bar and the frame. This wire pulls the fabric tight and keeps the bottom edge straight. It also prevents the fabric from being pushed up by snow. The tension wire should be installed with a turnbuckle so you can adjust the tension over time. The turnbuckle should be tightened until the wire is straight, but not so tight that it pulls the frame inward. The tension on the wire should be about 50 pounds.
If you are installing the gate on a slope, you need to account for the angle. The gate frame must be cut to match the slope. This is a complex job that requires a miter saw and a welder. Most people should not attempt this. Instead, buy a gate that is designed for a slope. Haisen offers gates with a sloped bottom rail. The rail is cut at an angle that matches the slope of your driveway. The angle is usually 10 degrees. You need to measure the slope of your driveway with a level and a protractor. Then, order the gate with the correct angle. If you try to install a square gate on a slope, the gate will not close properly. The hinge side will be higher than the latch side, and the gate will bind. I have seen this mistake dozens of times. The fix is to cut the gate frame and re-weld it, which is a lot of work. Better to order the right gate the first time.
The hardware for the gate posts is also important. The gate posts must be set with a concrete collar that extends above the ground by 2 inches. This prevents water from pooling around the post base. The concrete collar should be sloped away from the post to direct water runoff. If the concrete is level, water will sit against the post and cause rust. The post itself should be schedule 40 steel pipe with a diameter of 2.5 inches for gates up to 6 feet wide. For wider gates, use 3-inch pipe. The post wall thickness should be 0.065 inches for 2.5-inch pipe. The post must be set in the concrete with the hinge side facing the gate. The hinge pins are welded to the post at the factory. If you are using a post that does not have pre-welded hinge pins, you need to drill and tap the post for the hinge bolts. This is a precision job. Use a drill press and a tap set. The hinge bolt holes must be exactly 6 inches from the top and bottom of the post. The holes must be aligned vertically. If they are off by 1/8 inch, the gate will not hang straight.
Now, let’s talk about the latch post. The latch post is the same size as the hinge post. It must be set in concrete with the same depth. The latch post needs a hole for the latch bolt. The hole should be drilled at the same height as the latch on the gate. The height is measured from the ground to the center of the latch. The latch bolt is a 3/8-inch bolt that goes through the post and the latch bracket. The bracket is secured with a nut and lock washer. The latch post must be plumb in both directions. If it is leaning, the latch will not engage. I have seen a latch post that was leaning 2 degrees, and the gate would not latch without forcing it. The fix was to dig out the concrete and re-set the post. That is a lot of work. Check the plumb before the concrete cures.
The drop rod is a simple but effective feature. It is a steel rod that slides into a hole in the ground. The rod is attached to the gate frame with a bracket. The bracket is bolted to the frame. The rod is usually 1/2 inch in diameter. The hole in the ground should be 1 inch in diameter and 6 inches deep. Insert a piece of PVC pipe into the hole to keep the rod from rusting. The rod should be greased with the same lithium grease you used on the hinges. The drop rod is used when you want to keep the gate from being opened by wind. It is also useful for security. If you have a dog, the drop rod will prevent the dog from pushing the gate open. The drop rod is not a substitute for the latch. It is a secondary lock. Use both for maximum security.
One more thing about the tension wire. The tension wire is installed on the top and bottom of the gate. The top tension wire is installed in the same way as the bottom. The wire is attached to the tension bar and the frame. The top wire prevents the fabric from sagging at the top. The bottom wire prevents the fabric from being pushed up. The tension wires should be tightened with a turnbuckle. The turnbuckle should be tightened until the wire is straight. Do not over-tighten. The wire should be tight enough that it does not move when you push on it. The tension on the wire should be about 50 pounds. You can check the tension with a tension gauge. If you do not have a gauge, tighten the wire until it is straight and then give it one more half-turn. That is usually enough.
The gate handle is another detail. The handle is usually a lever that operates the latch. The handle is attached to the gate frame with a bracket. The handle should be installed on the same side as the latch. The handle is typically made of cast iron or steel. The handle should be greased at the pivot point. The latch mechanism should be adjusted so that it engages with a positive click. If the latch is too tight, it will not close. If it is too loose, it will rattle. The adjustment is usually a screw that moves the latch hook. Turn the screw clockwise to tighten the latch. Turn it counterclockwise to loosen it. The latch should engage with about 1/8 inch of clearance. Test the latch several times to make sure it works smoothly.
If you are installing the gate on a concrete driveway, you need to use a different anchor method. The gate posts cannot be set in concrete on a concrete driveway. Instead, you need to use a post base that is bolted to the concrete. The post base is a steel plate that is bolted to the driveway with concrete anchors. The post is then welded to the plate. This is a permanent installation. The post base must be level. Use a level to check the plate before you drill the holes. The holes should be drilled with a hammer drill and a masonry bit. The concrete anchors should be 1/2 inch in diameter and 3 inches long. The anchors should be set with a torque wrench. The torque should be 50 foot-pounds. Do not over-tighten the anchors. They will strip the concrete. The post base is available from Haisen or from a hardware store. The base should be galvanized to prevent rust.
The gate frame itself is assembled at the factory. The frame is welded at the corners. The welds are ground smooth. The frame is painted or powder-coated. The powder coating is more durable than paint. The powder coating is applied in a factory setting. The coating is baked on at 400 degrees Fahrenheit. The coating is 0.003 inches thick. The coating is resistant to UV light and corrosion. The paint is less durable. The paint will chip and fade over time. If you are installing the gate in a coastal area, choose the powder-coated option. The powder coating will last for 10 years or more. The paint will last for 3 to 5 years. The cost difference is about 20 percent. The powder coating is worth the extra cost.
The chain link fabric is attached to the gate frame with tension bands. The tension bands are U-shaped brackets that clamp the tension bar to the frame. The tension bar is a steel rod that runs through the end of the fabric. The tension bar is 1/2 inch in diameter. The tension bar is galvanized. The tension bands are also galvanized. The tension bands are available in different sizes. The size must match the diameter of the gate frame. The tension bands are installed with a bolt and nut. The bolt is tightened with a socket wrench. The tension bands should be tightened until the tension bar is clamped firmly. The tension bar should not move when you push on it. The tension bands should be installed at the top and bottom of the gate frame. The tension bands are also installed on the intermediate posts if the gate is wider than 4 feet. The intermediate posts are used to support the fabric. The intermediate posts are set in concrete. The posts are spaced 4 feet apart. The fabric is attached to the intermediate posts with tension bands and a tension bar. The fabric is tensioned with a fence stretcher. The tension should be about 200 pounds. The fabric should be tight enough that it does not sag. The fabric should not be so tight that it pulls the posts out of plumb.
One more thing about the gate width. The gate width is measured from the outside of the hinge post to the outside of the latch post. The gate frame is 1.5 inches narrower than the gate width. The gate fabric is the same width as the gate frame. The gate fabric is cut to size at the factory. The fabric is attached to the gate frame with tension bands and a tension bar. The fabric is tensioned at the factory. The tension is about 200 pounds. The fabric is tight enough that it does not sag. The fabric is not so tight that it pulls the frame out of square. The gate is shipped with the fabric attached. The gate is ready to install. The only thing you need to do is attach the hinges and the latch. The hinges are attached to the gate
