INSTALLATION INSTRUCTIONS
1. Using Mounting Bracket A (#1), identify the desired placement of the SUMO. The two tabs on
Mounting Bracket A must mount on the inside edge of the gate.
a. Place Mounting Bracket A in the desired position. Temporarily secure with one ½” Self-Tapping
Screw (#16) through the center hole on Mounting Bracket A.
b. On the inside of the gate, locate the bottom tab with a notch in it on Mounting Bracket A.
Draw a straight line from the bottom notch to the edge of the gate (See Diagram 1).
c. Place Mounting Bracket B (#2) on the opposite side of the gate. Line the bottom notch on the
bottom inside tab with the line drawn in Step 1b. (See Diagram 1).
d. Mount and secure Mounting Bracket B with a ½” Self-Tapping Screw through the center hole.
2. Insert Security Guide Bolt (#4) into the bottom hole on Mounting Bracket A with the bolt pointing
towards the fence post. DO NOT tighten set screw at this time.
3. Attach Keyed Guide Bolt Receiver (#5) to the bottom channel of Mounting Bracket C (#3).

Receiver onto Mounting Bracket C. After the Keyed Guide Bolt Receiver is installed on Mounting
Bracket C, unlock the receiver.
4. Hold Mounting Bracket C with Keyed Guide Bolt Receiver to the fence post. Hold in place until the
Security Guide Bolt is centered into the v-groove of the Keyed Guide Bolt Receiver, where the hook
