5. Color Choices

PlexiDor offers three elegant colors to compliment the decor of your home. Choose from White, Silver or Bronze. Silver frames feature an anodized finish. White and Bronze frames feature a baked-on powder coating for increased durability, similar to the appliances in your home. A PlexiDor Pet Door is by far the most attractive pet door you will ever install in your home.

Our finishes will integrate perfectly into your home!

  • The white finish highlights common household appliances as well as most baseboards and trims and blends with most traditional decors.
  • The silver finish coordinates with newer stainless-steel appliances and looks great in a modern setting.
  • The bronze finish works well with darker toned furniture and accessories by adding an updated feel to the room.

A baked-on powder coated finish is far more durable than conventional paint. 

Powder coated surfaces are more resistant to chipping,  scratching, fading, and wearing than other finishes.

Our Features

No Replacement Flaps
Replacement flaps are the biggest expense of low quality vinyl flap doors. PlexiDor saloon style panels will never shrink, fade or crack. Each panel is manufactured to withstand damage from extreme temperatures, UV / IR sunlight and heavy impact. The panels open and close quietly without banging. PlexiDor is the least expensive pet door to own over its lifetime.
Energy Efficiency
PlexiDor Pet Doors are designed to help save energy. Each panel is lined with industrial grade weather seal around all four edges to reduce air conditioning and heat loss. Whether you live in the hot desert climate of Arizona or in the frigid cold of Alaska, a PlexiDor will save you money.
Security Features
The door, wall, and glass series come with a cylinder lock ‐ simply turn the key to lock the rigid panels into place at night. Medium and larger doors also come with a 20 gauge steel security plate that can only be removed from inside the home. The Electronic series only opens for the RFID keys, and when inactive its composite panel door serves as a security plate.
Peace of Mind
Your family will enjoy the peace of mind that a PlexiDor Pet Door will provide, like freedom from the worry of damage to your floors and carpets. Your pet will love the freedom to relieve themselves anytime, either while you are away or at home involved with other tasks.
Color Choices
PlexiDor offers three elegant colors to compliment your home; Silver, White or Bronze. The frames are manufactured of anodized aluminum for a beautiful silver finish. The white and bronze frame finishes are baked on the surface for increased durability over plastic or paint.
K-9 Composite™
Our doors' extreme durability is thanks to a specially developed K-9 Composite™ exclusive to the PlexiDor. These precision, shatter-resistant panels make it easy for your pet to enter and exit while providing maximum energy efficiency for your home.
