Installation
Step 1:
Mounting
1 Layout the concrete pad as detailed in Figure 4. Be sure to locate electrical conduit inside the
hatched 14" x 13" area.
2 Excavate required area for pad and conduit. Pad depth should be below the frost line, or as
required by local codes.
3 Locate four 1/2" X 6" long L-bolts (not supplied) as shown in Figure 4. The L-bolts should
protrude 1 1/2" inches above the pad.
4 Pour concrete, insuring that the pad is level and above the ground line.
5 Allow the concrete to set at least two days before installing gate.
