PAD AND MOUNT
Figure 2. Pad and Mount.
1. The concrete pad must be sufficient to support the gate operator and the dynamic forces
created by the moving gate. LiftMaster recommends a pad 24” wide by 27” long by 30” deep.
2. The operator must be level and parallel to the gate, so the pad should be level and about 4”
above grade to prevent water entrance.
3. Four anchor bolts are required to secure the gate operator to the pad. The mounting holes in
the gate operator are 5/8” in diameter. Red Head bolts ½” x 3½“ are recommended.
4. Be sure to provide access for wiring conduits. In Master/Slave systems, remember to include
conduit stubs for separate inputs (if any) and for the Master/Slave connection cable between
gate operators.
NOTE:
Shading indicates conduit stub access areas .
