Thank you for choosing the COMOMY 55.1" Extra Tall Pet Gate. This gate is designed to safely contain pets, particularly cats and dogs, within designated areas of your home. Its extra tall design and narrow bar gaps help prevent pets from jumping over or squeezing through. The adjustable cat door provides convenient access for smaller pets, while the double-locking mechanism ensures security. This manual provides essential information for proper installation, operation, and maintenance to ensure the safety and longevity of your pet gate.
2. Important Safety Information
- Read all instructions carefully before installation and use. Failure to follow these instructions could result in injury or damage.
- This pet gate is intended for use with pets. It is not a substitute for adult supervision. Never leave children unattended near the gate.
- Regularly check the gate for proper installation and security. Ensure all tension bolts are tightened and locking mechanisms are functioning correctly.

6. Installation
The COMOMY Pet Gate can be installed using two methods: Pressure Mounted (no drilling) or Hardware Mounted (for maximum security). Choose the method best suited for your needs.
Pre-Installation Checks:
- Ensure the zip tie on the gate is intact. DO NOT CUT IT BEFORE INSTALLATION IS COMPLETE.
- Verify that the installation surface (wall/door frame) is clean, dry, and structurally sound.
- Confirm the gate frame is close to the floor and level.

This image displays a warning not to cut the zip tie before installation, with tips for what to do if it's cut accidentally. It also shows the gate's initial state with the zip tie and its final state after installation.

This diagram emphasizes that the bottom of the gate frame must be close to the floor with no overhang. It also shows correct and incorrect placement against a wall.

This image provides top and side views of the gate, indicating the correct alignment for installation to ensure stability and proper function.
Method 1: Pressure Mounted Installation (No Drilling)
- Insert Bolts: Insert the four tension bolts into the holes at each corner of the gate frame.
- Install Pedal (Optional): If desired, place the anti-stumble pedal at the bottom of the gate opening.
- Tighten Bolts: Position the gate in your desired opening. Turn the adjustment knobs on the tension bolts clockwise to extend them until they make firm contact with the wall/door frame. Continue tightening until the gate is securely held in place.
- Check Door Locks: Ensure the main gate's locking mechanism aligns and engages properly. If not, adjust the tension bolts further.
- Cut Belt & Test: Once secure, carefully cut the zip tie. Open and close the gate to test its stability and locking function.

This image provides a visual step-by-step guide for pressure-mounted installation, showing how to insert bolts, install the pedal, tighten bolts, check locks, and cut the zip tie.
Method 2: Hardware Mounted Installation (Recommended for Security)
- Locate Drilling Points: Place the gate in the desired opening. Mark the four drilling points where the wall cups will be installed.
- Drill Holes & Secure Wall Cups: Drill pilot holes at the marked points. Insert wall anchors (if needed) and secure the wall cups using the provided screws.
- Install Tension Bolts: Insert the tension bolts into the gate and align them with the secured wall cups. Tighten the bolts until the gate is firmly in place.
- Check Door Locks: Ensure the main gate's locking mechanism aligns and engages properly. Adjust tension bolts if necessary.
- Cut Belt & Test: Once secure, carefully cut the zip tie. Open and close the gate to test its stability and locking function.

This image provides a visual step-by-step guide for hardware-mounted installation, showing how to locate drilling points, drill holes, install tension bolts, check locks, and cut the zip tie.
Spacer Bar Installation (If Needed)
If the gap between the tension bolt and the gate frame is greater than 1.37 inches, use the provided spacer bars to reduce the gap and enhance security.
- Insert Screw: Insert the tension screw through an M10 nut, then through the hole in the spacer bar, and finally through another M10 nut.
- Screw into Side Hole: Screw the assembled tension bolt and spacer bar into the side hole of the gate.
- Adjust Spacing: Adjust the M10 nuts to ensure the gap is less than 1.37 inches.

This image provides a visual step-by-step guide for installing spacer bars if the gap between the tension bolt and the gate frame is too wide.

8. Maintenance
- Clean the gate regularly with a soft, damp cloth and mild soap. Avoid abrasive cleaners or harsh chemicals.
- Periodically check all screws, bolts, and locking mechanisms to ensure they are tight and secure.
- If the gate is exposed to moisture, wipe it dry immediately to prevent rust.
9. Troubleshooting
- Gate not closing or latching properly:
- Ensure the gate is installed level and plumb.
- Tighten the tension bolts evenly on all four corners to ensure adequate pressure.
- Check for any obstructions preventing the gate from closing fully.
- Gate feels wobbly or insecure:
- Re-tighten all four tension bolts.
- If using pressure mounting, consider switching to hardware mounting for increased stability.
- Small pets squeezing through gaps:
- Ensure the main bar gaps are no wider than 1.37 inches.
- If gaps exist at the sides due to uneven walls, install the provided spacer bars as per the installation instructions.
- Cats jumping over the gate:
- While this gate is 55.1" tall, some exceptionally agile cats may still attempt to jump. Ensure the gate is installed at its maximum height and consider additional deterrents if necessary.
