Glass Patio - What Locking Options Are Available?

Our Glass Patio Pet Door is designed with flexibility in mind, offering multiple locking options to suit a range of home setups and security needs. Whether you're renting or looking for a more permanent solution, there's an option that works for you. 

We currently offer two versions of the Glass Patio Pet Door:

• Version 1 (V1) — Available from 2023 to June 2025

• Version 2 (V2) — Released from June 2025 onwards

Each version includes key updates to installation and design features, so it's important to identify which one you have before purchasing accessories or replacement parts.

Glass Patio - General - How to Differentiate Between V1 & V2 Glass Patio Pet Doors

Note: The Glass Patio Pet Door is not a security door and should not be used as a primary security measure. While built from strong aluminium and tempered glass, we recommend using the semi-permanent locking system (drilled sliding door brackets, toggle lock or sliding door bar lock) for better security. It’s the customer’s responsibility to ensure the door is suitably secure.

V2 Glass Patio Pet Door ( June 2025 > )

The V2 Glass Patio Pet Door is designed to work with a variety of sliding door setups. It offers flexible locking options to suit both renters and homeowners looking for a more secure, permanent solution.

For the most secure fit, we recommend installing the insert in a way that allows your sliding door to lock directly onto the Patio Pet Door, giving you added stability and peace of mind.

Step-by-step instructions, along with imagery, is available within the installation guide for the V2 Glass Patio Pet Door online.

Lock Compatibility

Compatible Door Hardware

• Doors with standard latch-style locks

• Doors with internal frame-mounted locking mechanisms

• Doors that allow for realignment or removal of the locking hook/latch

Incompatible Door Hardware

Installation Guide: Internal Lock Side

If your sliding door has a lock built into the inside frame, follow the steps below to reinstall the internal latch onto the Glass Patio Pet Door. 

1. Unscrew the locking hook/latch from your sliding door frame.

2. Test alignment by inserting the hook into your sliding door's locking mechanism.

3. Install the Glass Patio Pet Door into your door frame with the lock bolts facing inside your home.

4. Close the sliding door against the Patio Pet Door.

5. Mark the position where the locking hook touches the Glass Patio Pet Door.

   • Note: If this position aligns with one of the door’s existing screws, remove it and reinstall it through the hook.

6. Reattach the locking hook to the Glass Patio Pet Door using self-tapping screws (not supplied).

   • You can reuse the screws from your original latch.

Installation Guide: External Lock Side (Using Lock Bracket Pack)

If your sliding door’s handle and lock are on the outside of the frame, use the Lock Bracket Pack supplied with your Patio Pet Door. Follow the steps below:

1. Unscrew the lock catch from your sliding door frame.

2. Install the lock catch onto the provided Lock Bracket using the supplied bolts.

3. Lay the Patio Pet Door flat on the ground.

4. Slide 3 bolts into the Patio Pet Door track, then position the Lock Bracket on top, aligning with your door lock.

5. Reinstall the Patio Pet Door into your sliding door frame.

6. Raise the Lock Bracket to meet the lock on the sliding door.

7. Secure the bracket using the washer and dome caps. Tighten with the tube spanner.

   • Important: Do not overtighten — this may damage the thread.

8. Optional: Trim the Rubber Air Gap Seal if needed and place it behind the Lock Bracket to prevent it from rubbing against the door.
