MaxSeal® PRO Pet Door
Best Insulating Dog Door for Doors

Most Secure Pet Door | Durable Hinged Flaps

MaxSeal Pro dog door for door installation

The newly designed MaxSeal® PRO pet door for doors 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. All Security Boss products are hand built to order.

MaxSeal Pro dog door for door installation Single Flap versus Dual Flap Information The MaxSeal® pet door for doors 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 for doors is design to fit on any type of door surface from smooth to panel designs. It will self adjust to fit door thicknesses of 1 1/4" to 2". The two frames are attached to each other, so from either side one cannot see any attachment screws. Currently the exterior security panel is not available on the Door Model.

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.

Child Safety:
Security Boss Manufacturing, LLC., recommends that households with small children need to exercise proper judgment with leaving their children unattended in any area with a pet door. Pet Doors come with locking panels and locking devices, using these devices minimizes any risk, but does not replace proper parental supervision.


We recommend that any consumer that installs their own pet door wear eye protection and be familiar with the construction procedures and tools of installing a pet door.

Virtually all doors use magnets for the activation of the pet door as well as in the sealing of the flaps. Customers with certain medical devices, for example; Pace Maker patients, should consult their physician.

    Superb Quality and Peace of Mind

    Posted by Jesse Granat on Feb 5th 2023

    Searching for a pet door for our dogs and this pet door is superior in all ways compared to any others I searched out. The frame is sturdy and solid, the magnets are superb and close both flaps with ease and a 'snap!', the locking panel which thankfully is customizable for top, left or right side works wonderfully and gives me peace of mind at night in the city. Great value for the price even with our Canadian Dollar being so horrible right now. I would highly recommend this door to anybody looking for one. Five Stars. And Install was extremely easy. Thank you Security Boss Pet Doors!
