Assembling and Installing Your Gate




- Determine Width: Measure your doorway. If the opening is between 34.5" and 37.5", skip to Step 3. If between 46.5" and 58.5", proceed to Step 2.
- Attach Extension: Use the 4 double-ended screws (F) to fasten the extension panel (B) to the main gate panel (A).
- Insert Rods: Insert the 4 threaded rods (D) into the four corners of the assembled gate. Do not fully screw them in yet.
- Mark Holes: Use the paper wall mounting template (C) to mark the exact locations for the mounting brackets on the wall.
- Attach Brackets: Use the 8 screws (E) to attach the 4 mounting brackets (G) to the wall at the marked locations.
- Mount Gate: Insert the flat ends of the threaded rods into the semi-circle slots on the mounting brackets. Install one side completely before the other.
- Final Adjustment: Adjust the threaded rods so spacing is equal on all 4 corners. Use a wrench to tighten the locking nuts. Ensure the exposed threaded rods do not exceed 2.5 inches.
Operating the Door Latch
To open the gate, press the release button down on the handle and slide the handle back towards the hinge. This operation is the same for closing the gate.

Care and Maintenance
Periodically check the gate for signs of damage, wear, or missing components. Do not use the gate if any part is missing, worn, or damaged. Ensure all hardware and mountings are tightened. Clean by sponging with warm water and a mild detergent; do not use abrasive cleaners or bleach.
