White Glass Patio Pet Door for Sliding Doors - Medium, Locking Panel

Our review of the White Glass Patio Pet Door finds it best suited to pet owners who need a sturdy, rental-safe option for medium dogs using sliding glass doors. The biggest reason to buy is the flexible installation: a new spring jack mechanism lets this pet door be pressure mounted without drilling, while included permanent mounting parts give a secure long-term fit. The clear tempered glass and aluminium frame keep sightlines and durability high, and the locking panel adds simple, reliable control over pet access.

Key Features

• Adjustable height frame: The frame adjusts from 77.2 to 83.5 in to fit most sliding door openings and works with existing internal or external locking hardware.
• Rental-safe installation: The spring jack mechanism allows a secure pressure mount so renters can install the door without drilling into the frame.
• Permanent mounting option: Included permanent mounting parts let owners convert to a fixed installation for added security when desired.
• Locking panel: The slide-in locking panel closes the pet flap completely to prevent outdoor access when you need full security.
• Durable, clear glazing: Crystal clear tempered glass panels preserve the view while the aluminium frame resists rust and stays lightweight.
• Weather resistant flap: A magnetic centring catch and adhesive weather seals reduce drafts and keep the flap closing reliably after use.

Who It's For

This pet door is aimed at households with medium sized dogs where the flap dimensions (8.9 in wide x 12.4 in high with lowest flap edge 3.9 in from the ground) match the pet's size. It is especially useful for renters and homeowners who want the option to install without drilling and later switch to a permanent fit.

Owners of very small dogs, large breeds, or households that need a fully custom-shaped opening should look elsewhere, since the flap size and rectangular frame are designed specifically for medium dogs and standard sliding door profiles.
