• Lock and key — restrict access through the pet door when needed.
• Premium weather seal — helps minimize heat and cooling loss.
• Dual shatter-resistant Plexiglass panels — provide a solid-panel alternative to a flap-style door.
• Anodized aluminum frame — forms the door’s frame.
• Made in the USA with a 10-year warranty — provides domestic manufacture and the manufacturer’s stated warranty period.
• Fits fiberglass, wood, steel, or glass doors — offers several door-material options for installation.

A pet door makes it easier for cats and dogs to move between indoors and outdoors without relying on someone to open the door each time. The PlexiDor Performance model combines pet access with a locking mechanism and a weather seal, making it suited to homes where access control and reducing heat or cooling loss matter.

How does the PlexiDor Performance pet door differ from a flap-style door?

It uses dual Plexiglass panels instead of a flexible flap, and its lock-and-key mechanism can prevent unauthorized access through the opening. The panels are shatter-resistant, while the anodized aluminum frame provides the surrounding structure. The white finish gives the door a neutral appearance for a range of home interiors.

• Panel construction: two Plexiglass panels.
• Frame material: anodized aluminum.
• Finish: white.

Which door materials can it be installed in?

The PlexiDor Performance pet door is designed for installation in fiberglass, wood, steel, or glass doors. Choose the installation approach that suits your project: the door is designed for DIY installation, and PlexiDor also has a nationwide network of professional installers available to service homes.

• Compatible door materials include fiberglass, wood, steel, and glass.
• Installation options include DIY or help from a PlexiDor professional installer.

How does it help with indoor comfort and security?

The weather seal is designed to minimize heat and cooling loss while allowing pets to pass through. When you want to restrict passage, the lock-and-key mechanism secures the pet-door opening against unauthorized access. This combination supports everyday pet access while giving households a way to control the opening.

• Weather-seal design addresses heat and cooling loss.
• A key-operated lock provides a way to prevent access through the pet door.

The PlexiDor Performance is suited to cat and dog owners looking for a door-mounted pet access point with panel construction, a locking option, and compatibility with several common door materials. It is manufactured in the USA and comes with a 10-year warranty. Its dual Plexiglass panels, anodized aluminum frame, weather seal, and lock-and-key mechanism bring pet access and access control together in one door-mounted design.
