Additional Items For Purchase

The following items are REQUIRED to complete
the installation:
CONTROL BOX MOUNTING HARDWARE
• Mounting to Wood:
Four #8 x 1-1/2" wood screws
• Mounting to Brick/Cement/Masonry:
Four 1/4" masonry screws 1-3/4" long
• Mounting to Metal:
Four #10-32 machine screws with washers and
lock nuts
GATE BRACKET MOUNTING HARDWARE
For 1 or 2 inch circular or square tubular constructed gates, use
the following U-bolts with associated fl at washers and hex nuts:
• 1" use 5/16-18 x 2-3/16" U-bolt (2)
• 2" use 5/16-18 x 3-3/16" U-bolt (2)
To secure the bracket to the gate, use the following hardware:
1/4-20 x 3" hex head bolt with associated fl at washers, lock
washers and hex nuts (2).
For gates with fl at mounting surfaces and a maximum thickness
2", an alternate to using U-bolts would be: 5/16-18 x 3" hex
head bolt with associated fl at washers, lock washers and
hex head nuts (4).
For chain link fences or other types with circular rails, it is best
to attach a vertical support panel connecting the top rail to the
bottom rail. The gate bracket can then be mounted to this vertical
panel using the same bolts, washers and nuts as mentioned above.
POST BRACKET MOUNTING HARDWARE
Two 3/8-16 x 6" carriage bolts with fl at washers, lock washers and
lock nuts.
