MaxSeal® PRO Pet Door
Best Insulating Dog Door for Walls

Most Secure Pet Door | Durable Hinged Flaps

MaxSeal Pro dog door for door installation
The newly designed MaxSeal® PRO pet door for walls features the newest design and functions available in pet doors today. New features include a metal 1" insulated interior security panel that provides the most security of any pet door when locked. The flaps of the MaxSeal® PRO have a unique aluminum hinged connection that allows for the flap movement to swing more freely as well as eliminating the pinch of the flap when larger dogs use the pet door. This results in your flaps lasting much longer between replacements. The MaxSeal® PRO still offers the best warranty on the market which covers the door and the flaps for up to 6 years from defect. It also has a 1-year replacement option for dogs that chew or destroy flaps.

Single Flap versus Dual Flap Information MaxSeal Pro dog door for door installation The MaxSeal® pet door is made with high grade aluminum material that is naturally rust resistant. This door will not only last but will look great throughout the life of the door. The durable piano hinged vinyl flaps are UV treated and weatherized to prevent shrinking, cracking, discoloring and warping. Most flap brands simply do not hold up against harsh environments (direct sunlight, extreme temperatures, overuse, etc). Staggered stainless strike plates are riveted to the sides and base of the flap, connecting to powerful embedded magnets in the aluminum frame, creating an exceptional air seal.

Best Pet Doors by Design™

The MaxSeal® PRO comes standard with a 10" trim-to-fit solid aluminum tunnel. For larger walls a 16" trim-to-fit tunnel is optional. This solid tunnel design deters moisture issues that can develop in cheaper design products. Indoor / Outdoor carpeting is included with your purchase to line the sides and bottom of the tunnel. We recommend using silicone to adhere the carpet to the tunnel. This will allow you to easily remove the carpet for replacement every few years. Adhesive can make this removal process very difficult.

Note: Existing MaxSeal® Customers can Upgrade their MaxSeal models by purchasing the interior security panel and the hinged replacement flaps for their size of door. Call us if you would like any assistance.
