Mounting Bracket Installation
Examine Figure 2 for details on the required mounting
locations for the brackets. They must be mounted at the correct
locations to allow the operator to open the gate at a 90 degree
angle and to ensure the operator functions smoothly.
The brackets must also be mounted level in respect to each
other so the operator’s front and rear mounting points are
vertical and not offset at an angle.
1. Measure approximately halfway up the gate height and determine
good strong spots located in the required areas to mount the brackets
on the post and gate.
2. Using Figure 2 as a guide, mark the locations on the post or pillar
and the gate for the mounting brackets. The top surface of the post
bracket must be 3/8” below the top surface of the gate bracket to
allow for the bolt-on operator bracket’s 3/8” thickness.
✓ NOTE: Depending on the gate design, an additional reinforcing
plate welded to the gate may be required to provide a good spot to
mount the gate bracket.
Universal Post Bracket Installation
✓ NOTE: When installing the post bracket on a round post or masonry
pillar, use improvised methods (additional plate with lag bolts and anchors,
concrete wedge anchors, U-bolts, etc.) to securely fasten the bracket.
1. Tack weld the post bracket to the post at the marked spot and
double-check its level and height.
2. Finish welding the post bracket to the gate post and allow the weld to cool.
3. Attach the bolt-on operator bracket to the post bracket at the correct
depth and angle using three bolts and locknuts (there are 18 possible
positions). Install the operator bracket pin as shown in Figure 3.
Gate Bracket Installation
Before welding the gate bracket, be sure the centers of the
operator mounting holes on the brackets will end up 29-1/2”
apart when the gate is fully closed.
1. Tack weld the gate bracket to the gate at the marked spot and
double-check its level and height.
2. Finish welding the gate bracket to the gate.
3. After the welding is completed and the gate bracket has cooled,
snap the limit switch magnet assembly onto the gate bracket (see
Figure 4).
4. From the top side of the gate bracket, slide the load bushing into the
bracket hole.
Alternate method to locate the gate bracket:
1. Hold the gate bracket with the magnets installed onto the LRA traveler.
2. Run the unit to the full open position.
3. Place the rear of the arm onto the post bracket.
4. Manually fully open the gate.
5. Position the gate bracket in the required position.
6. Remove the magnet assembly and bolt or weld the bracket in place.

WARNING
The gate must be installed in a location so that enough
clearance is supplied between the gate and adjacent structures
when opening and closing to reduce the risk of entrapment.
Swing gates shall not open into public areas.
