PAD MOUNTING
1. Layout the concrete pad (Figure 2). 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. Pour concrete pad. Concrete pad should be level and above
the ground line.
4. Allow the concrete to set at least two days before installing
operator.
5. Secure operator with four concrete anchors (not provided).
ARM FABRICATION
MODEL BG770 (SINGLE ARM)
If you are making the arm yourself, refer to Figure 3 and its
suggestions for the single arm design.
1. Drill four 1/2" diameter holes using the arm clamp as a
template. Tapering the wood as shown helps reduce the weight
and allows you to reduce any warping common with long
lengths of lumber.
2. Finish arm with exterior grade paint and stripe with paint or
adhesive backed tape as required.
MODEL BG790 (WISHBONE ARM)
A 24' wishbone arm is provided as standard with every BG790
gate. If a shorter arm is desired, the extension may be shortened
(Figure 4). The maximum arm extension is 8' for a total arm
length of 24'.
1. Cut to desired length.
2. Finish with an exterior grade paint and stripe with paint or
adhesive backed tape as required.
