Installing a pet gate is one of the simplest ways to create safe boundaries inside your home whether you’re keeping a dog, cat, puppy, or small pet away from certain areas. A correctly installed gate prevents accidents, protects restricted spaces, and offers peace of mind. Based on the video instructions, here is a detailed 10-step guide rewritten for easy understanding and smooth setup.
Tools Required for Installing a Pet Gate
Before you begin the installation, gather a few basic tools that will help you set up the pet gate correctly. Having everything ready ensures a smoother, faster process and prevents unnecessary interruptions during installation.
Essential Tools

- Tape Measure: To measure the width of your doorway or opening
- Flathead Screwdriver: Needed for attaching extension connectors
- Philips Screwdriver: Used for securing mounting cups to the wall
- Utility Scissors or Cutter: To remove the zip tie once the gate is nearly installed
- Adjustment Wrench (Included with Gate): For tightening tension knobs precisely
- Pencil: for marking the placement of mounting cups
Optional Tools (Helpful for Accuracy)
- Level Tool: Ensures your gate is perfectly straight
- Penny or Thin Coin: For checking the 1/16-inch locking gap
- Extra Screws or Wall Anchors: Only if you prefer a more permanent hold
Step 1: Measure Your Opening Before You Begin

Before installing your pet gate, always start by measuring the width of the doorway or opening. This tells you whether the main gate will fit as-is or if you’ll need to add extensions. Accurate measurements help prevent readjustments and ensure your gate fits securely.
What to do:
- Measure the full width using a tape measure.
- Compare your measurement to your gate’s recommended width range.
- Decide whether you need extensions for wider openings.
Step 2: Understand the Gap You See After Unboxing

When you unpack a pressure-mounted pet gate, you’ll see a noticeable gap between the frame and the gate door. This gap often confuses people, but it’s completely intentional. It is what allows a pressure-mounted gate to tighten and lock securely once installed.
Why the gap exists:
- It provides space for the tension knobs to pull the frame inward.
- It ensures the door locks properly once the gate is tightened.
- The zip tie keeps the frame aligned during shipping.
Important notes:
- Do not cut the zip tie early; the gate may feel loose or uneven.
- The gap will gradually disappear as you tighten the tension knobs.
Step 3: Decide Whether to Use Mounting Cups

Mounting cups add extra stability by preventing the tension knobs from slipping or shifting. They’re especially helpful if you have energetic dogs, if the opening has slick surfaces (like painted walls), or if the gate is placed in a high-traffic area.
Why you might want them:
- Provides a more secure hold
- Protects wall surfaces from pressure marks
- Helps prevent the gate from leaning over time
Using mounting cups:

- Hold the gate in position and mark cup placement with a pencil.
- Peel off the adhesive backing and apply the pads into the cups.
- Secure each cup to your wall or doorway using a screwdriver.
- Make sure the cups sit straight and evenly.
Step 4: Prepare Gate Extensions if Needed

If your opening is wider than the main gate frame, attach the included extensions before installation. Preparing them early helps everything align properly later.
How to prepare them:
- Attach the connector pieces to both ends of each extension.
- Use a flathead screwdriver if needed to tighten them.
- Remove the gate frame inserts and keep them nearby.
Step 5: Attach Extensions to the Gate Frame

Once the extensions are ready, connect them to the main gate frame. This step determines the full width of your pet gate assembly.
Why alignment is important:
- Uneven extensions can make the gate tilt
- Proper alignment ensures the door swings smoothly
- Helps maintain even distribution of pressure
Steps:
- Slide the connecting pieces into the gate frame ends.
- Reinsert the frame inserts to close the ends neatly.
- Repeat for a second extension if your doorway requires it.
- Make sure both sides extend evenly.
Step 6: Insert the Tension Knobs

Tension knobs are essential for pressure-mounted gates because they secure the frame tightly without drilling large holes.
Install the knobs like this:
- Insert one tension knob into each corner of the gate.
- Make sure they’re aligned so they apply even pressure to the walls.
- Confirm the top knobs sit exactly above the bottom ones.
- Repeat the process if both sides have extensions.
Step 7: Position the Gate in the Doorway

Setting the gate in the correct position ensures that tightening the knobs will create even, reliable pressure. This also prevents the frame from warping or leaning.
What to check before tightening:
- The gate should feel balanced and centered.
- All four knobs must touch the wall surface.
- The gate should be perpendicular (not leaning forward or backward).
- Ensure the door has room to swing without obstruction.
Pro tip:If you have a level tool, place it on top of the gate to ensure a perfectly straight alignment.
Step 8: Tighten the Tension Knobs (Bottom First)

This step locks the gate into place. Tightening the knobs gradually builds pressure against the walls, reducing the frame gap and improving stability.
Tightening sequence:
- Tighten the bottom knobs first for a steady base.
- Then tighten the top knobs to keep the gate upright.
- Ensure both sides have equal exposed thread for balanced pressure.
- Once the gate stands securely on its own, you can cut the zip tie.
Step 9: Make Final Adjustments and Check the Latching Gap

Use the included wrench (or your gate’s adjustment tool) for precise tightening and alignment. This ensures the door closes smoothly and locks correctly.
Final checks:
- Continue tightening until the gap between the lock and frame is about 1/16 inch.
- Use a penny to measure the gap; it’s the perfect size.
- Check that the door swings easily in both directions.
- Ensure it auto-closes and locks properly.
- If it doesn’t, adjust the tension knobs slightly.
The 1/16-inch gap ensures that the gate door locks properly without resistance, making sure it swings and locks easily.
Step 10: Test the Gate Before Regular Use

Before using the gate daily, test it to make sure everything works safely and smoothly. This step ensures the gate is ready to keep your dog, cat, or other pet safely contained.
How to operate your pet gate:
- Pull back the release button.
- Lift the door gently to unlock.
- Swing it open in either direction.
- Release and confirm whether it auto-closes and locks.
- If anything feels unstable, recheck alignment.

FAQs
1. Why is my pet gate still loose after tightening?
Make sure all four tension knobs touch the wall evenly before tightening so start tightening from the bottom knobs, then the top ones. If it still feels loose, add mounting cups for extra grip.
2. How do I fix a pet gate that won’t close properly?
Check whether the 1/16-inch latching gap is correct using a coin then adjust the tension knobs slightly on both sides to level the frame. Ensure the gate isn’t tilted forward or backward.
3. What should I do if the extensions don’t align evenly?
Remove the extensions and reattach the connector pieces firmly. Make sure both sides extend the same length before tightening. Use a level tool to keep the gate straight during setup.
