Installation Manual for Cantilever Gates
Step 1: Receiving Your Products
Check to make sure you have received the proper parts within 5 days of receiving your kit using your packing list enclosed with your shipment. You may access the material list for your size gate from its respective page.
Step 2: Layout
Drive two wooden or steel stakes into the ground to be used to attach string line. These will be used as a guide to install your gate. You will be setting your gate posts to this string approx. 1/4" - 1/2" from this line. Stretch masonry string from one stake to the other. Make sure the masonry string is tight and free of obstructions. This string line will represent where your gate will be once installed. Adjust stakes and string line if necessary. (Fig. A)
Step 3: Setting Posts
Cantilever gates require 3 posts which make them unique; two are used to mount the rollers and gate and a third is required as a latch post. The (2) roller posts will be the same size and larger than the latch post. Although the latch post is smaller in diameter, you will set it in concrete the same distance from your guide string as the roller posts. The cantilever latch makes up for the offset once the gate is installed. Cantilever gates only have chain link stretched in the opening portion of the gate. The counterbalance is not stretched with chain link as it is typically behind the rest of the fence. Do set your gate opening posts at the ordered size. The portion of the gate which is stretched is typically 6" wider than the opening to provide security where the rollers will offset the gate. (Fig A-1)
Fig A-2 shows the top view of the gate once installed. The offset between the latch post and the latch side of the gate is provided for by the cantilver latch. For locating placement of the post to the far right of the above drawing, lay gate flat on ground. From the latch side of the gate, measure towards the counterbalance and make a mark at the gate opening size. Place a roller onto the rail at the far edge of this mark (counterbalance side). Next lay the last roller tight against the far side of the counterbalance next to the stop as shown below. Measure center to center on the two rollers to locate the placement of the roller posts. Hardware varies therefore it is always best to take measurements once you receive your gate to plan installation.
To set gate posts, dig holes 12-18" in diameter and 42-48" deep. The depth and diameter of the concrete footers vary depending on your location. The hole size above works well in areas that have freezing ground. The holes should be "bell-shaped" not "carrot-shaped" (Fig. B). Next, fill hole(s) with concrete and "stick" the post into the wet concrete and plumb post with a level. Make sure your concrete consistency is not too wet or soupy. Concrete should be of a plastic-like consistency, dry enough so the post will not sink to the bottom of the hole. The gate post should NOT extend to the bottom of the hole; there should concrete under the post as well as all around it. You will want to leave the concrete level approx. 2-4" below grade or the ground level especially in areas which freeze, back fill with dirt. Replumb post. When the ground freezes it can cause the concrete footer to "heave" if you fill the concrete to the top of the hole. Leave the post(s) alone for approx. 24 hours or a sufficient amount of time for the concrete to harden.
Step 4: Install Bottom Rollers
After the concrete has hardened, you may install the bottom rollers. Cantilever rollers (Fig D) bolt onto the roller posts using U-bolts. The rollers will come with preinstalled grease fittings, pack these first. Remove the four nuts and strap roller onto post at desired height. Set the height of the roller on the high post first approx. 2-4" above ground level. Tighten this roller and install other roller level to the first.
Step 5 Install Top rollers
You can install the top rollers now. Handtighten the nuts enough so the rollers won't slide down the post higher than necessary. These will need lowered onto the gate frame once it is upright. Lay the gate flat on the ground so that the bottom rail of the gate is resting on the bottom rollers. Center the entire gate on the two rollers. Make sure that the rollers are level to one another as it is the last convenient time to adjust them.
Step 6: Hang Gate
This step usually requires a few extra hands. The gate needs lifted so that the bottom rail is resting on the two bottom rollers. Once the gate is upright, a person needs to climb a ladder and lower the top rollers onto the top rail of the gate and tighten the nuts securing the rollers. When tightening the U-bolts, leave approx. 1/2" space between the top rail and the roller; otherwise the gate frame will bind up on the gate frame. Once all nuts are tightened, slide the gate back and forth and adjust as necessary.
Step 7: Installing Cantilever Roller Covers
Roller Covers (Fig E & F) typically install using the U-bolts of the rollers. Slightly loosen these and slide covers on and tighten. These protect the pinch points of the rollers.

Step 8: Install Latch
The next step is to install the cantilever latch if not using an operator. The latch simply bolts around the latch post. These usually bolt slightly above waist level or at any convenient level. Electric locks, used with operators, will come with their own installation manual.
