Made to order for sliding glass doors, this Liberty patio panel gives pets easy everyday access with a clean non permanent fit, energy efficient safety glass, an adjustable step over, and secure locking options.

The Liberty Custom Patio Panel is the kind of sliding door pet door people usually want when they are trying to avoid a bigger project. It is made to order for the patio opening, installs into the existing track, and gives you a cleaner finished look than a basic temporary insert while still avoiding permanent changes to the door.

What makes this model especially approachable is how much practical adjustment it gives you. The panel height is built around your track range, and the step over can be changed to better suit a taller dog, a shorter dog, or a pet that needs an easier threshold. That flexibility adds a lot of real world value when you are trying to fit both the door and the pet instead of compromising on one or the other.

The flap system is designed around everyday comfort rather than premium extreme weather performance. The clear vinyl flap stays easy for pets to use, while the magnetic closure and weatherstripping help the panel stay more controlled in changing temperatures, rain, and normal wind exposure. For many homes, that lands in a very practical middle ground between convenience and weather protection.

The panel is secured from the inside once installed, the closing cover gives you a reliable way to block access through the pet opening, and the track can be reinforced with additional locking accessories when needed. That makes it a better fit for shoppers who want convenience for the pet without leaving the opening feeling too exposed. 

Installation & Fit

  • Fits sliding glass door tracks at least 1 inch thick
  • Mounts into the existing patio door track with a spring loaded top for easy placement and removal
  • Secures from the inside with a spring loaded adjustment lock that prevent the panel from being lifted out from outside

Ideal for:

  • Homes, rentals, and vacation properties where a patio pet door needs to go in without cutting the door or wall.
  • Pet owners who want a made to order panel that looks integrated rather than temporary.
  • Dogs who benefit from an adjustable step over, including shorter pets and pets that need an easier threshold.
  • Sliding door households that want everyday pet access with a clear flap and good visibility through the opening. .

Questions

Can an intruder remove a dog door for sliding glass doors from the outside?

No, the adjustment locks are on the inside of the panel, so once installed, the Endura Flap Panel cannot be lifted out and removed without first loosening the adjustment locks from inside the home.

Can I install it myself?

It is meant to easily be put in and removed. You just have to loosen the screws at the top, fit it into the track, and then tighten them. Then to remove it you simply loosen them again and pop it out.

Can you lock the pet door?

It comes with a closing cover, and you slide that in on the inside of the house. It is a very secure ABS plastic material that is as strong as a 16 gauge steel.

Do not know which size to get? Here is a measurement guide to help you out.

Track Height Adjustment range
is based on the measurement of your sliding door track height from the
lowest point of your track to the highest point. Each Liberty Pet Door
Panel has a 3" adjustment range. Review our Track Measuring Guide video for additional, detailed information.

If your measured track height does not fall within one of the ranges above, we can make a custom height! Custom height option may take up to 4 weeks to special order the glass and build the panel.
