Installation Overview for Pull-To-Open Gates PUSH-TO-OPEN installation instructions begin on page 31. The diagram shown below is an example of a pull-to-open installation on a chain link fence and single gate. Mounting the opener on a masonry column requires special procedures; see Column Installation Information on page 37 if you intend to mount the opener on a column. Furthermore, if you have a push-to-open gate, you will need to purchase a push-to-open bracket [FM148] to properly configure your system.
Installation OF of Mounting INSTALLATION MOUNTINGHardware HARDWARE We recommend you position the opener near the centerline of the gate to keep the gate from twisting and flexing and to avoid backsplash from rain water. The Post Bracket Assembly The position of the post bracket assembly determines the leverage and efficiency of the opener. The post bracket assembly position also sets the clearance between the opener and the gate in the open and closed positions.
Post Bracket Assembly Install Post Bracket Assembly and Gate Bracket Step 1 Insert the 3/8" x 2" bolt through the center hole of the post brackets and post pivot bracket as shown. Fasten a 3/8" lock washer, 3/8" washer and 3/8" nut on the end of the bolt. DO NOT overtighten the nut because the post pivot bracket will have to be adjusted later. 3/8" x 2" Bolt NOTE: The following steps are intended for pull-to-open gate installations. If you are mounting your opener on a push-to-open gate (e.g.
IMPORTANT: While determining the mounting point for the post pivot bracket assembly, be sure that the position allows for minimum 2 inches of clearance between the gate and the opener in both the open and closed positions, as shown in the diagrams below. This clearance will give the opener the most efficient leverage point for opening and closing the gate and more importantly provides the least possible pinch area.
Installing the Post Bracket Assembly and Gate Bracket Step 1 Mark reference points for bolt holes on the fence post through middle of bracket slots. Mark reference points for bolt holes on the gate cross member through middle of gate bracket slots. Marking reference points in this manner allows room for adjustment when mounting the post bracket assembly and gate bracket. After marking your reference points, remove the opener and brackets from the fence and gate.
MOUNTING THE OPENER Step 5 Attach the opener to the securely bolted post bracket assembly and gate bracket using clevis pins, bushings, and hairpin clips, or optional Pin Locks (FM133). Verify that the opener is level and adjust the post bracket assembly if necessary.
At this stage of the installation, the opener should be installed on the gate and the closed position stop plate should be in place. Check List • The gate is plumb, level, and swings smoothly on its hinges. • A plate or support was added for the gate bracket (if necessary). • The opener is level and mounted on the centerline of the gate. • All hardware is tightened at this time.
