PULL-TO-OPEN BRACKET MOUNTING INSTRUCTIONS

NOTE: The mounting illustrations represent a typical installation using the provided gate hardware. The gate opener may also be
installed by welding it to the gate structure. For push-to-open installation order accessory kit 50-19503.
1. Place pull-to-open bracket on top of the post bracket. Insert
3/8" hex bolt through middle hole and secure with lock
washer, flat washer and nut. Insert 5/16" hex bolt through
hole in pull-to-open bracket and post bracket. Secure with
washer, lock washer and nut (Figure 1).
NOTE: Do not pivot bracket, bracket must be straight or you may
damage your gate, operator or gate post bracket.
2. Determine the vertical position of the gate post bracket
assembly on the gate post by aligning the gate post bracket
with one of the cross members of the gate. For optimal
performance, align the gate post bracket to a cross member
that is as close to the vertical center of the gate post as
possible. Level gate post bracket assembly and temporarily
secure to gate post using C clamp (Figure 2).
3. Move the gate post bracket assembly to obtain desired
dimensions. Ideally, the distance between and opener hinge
points should be approximately 7" (18 cm) x 7" (18 cm).
Place opener against gate post and adjust the opener until
the required dimension is achieved (Figure 3).
