Security Boss MaxSeal Replacement Flaps

Insulating Flaps to Replace Your Old MaxSeal Flaps

MaxSeal flaps are specific to size as well as their location of interior or exterior on your pet door. A interior flap will not line up correctly with the magnets of the exterior frame and vice versa. The magnet placement of both the interior and exterior of your pet door are designed to provide you with an optimum seal. Altering the placement of these magnet positions will affect the performance of your door. All Security Boss products are hand built to order.

Replacing your MaxSeal flaps is easy and can be done without removing the pet door frames. Thumbscrews located at the top of the flap can be loosened by hand or by Allen wrench (Provided in your hardware packet when you purchased the door). If you have any difficulty you can place a Flathead screwdriver behind the flap and apply some pressure to allow thumbscrews to catch.

*Note: Thumbscrews & Allen wrench are included with flap purchase

EXCHANGES: Exchanges accepted within (14) days from the day you received the product (exclusions apply).

What type of material is the handle?

Each kennel door comes with a strong, lockable stainless steel handle. Inside the handle is a stainless steel spring that helps keep the latch closed, so your dog can’t push the door open. It’s safe and secure, but still easy to open with one hand. You can also add a padlock or clasp for extra security if needed.

Are these kennels easy to assemble?

Your kennel ships with easy assembly instructions, covering all essential components:

Kennel panel setup
Panel-to-panel coupling
Handle & quick-lock latch installation
Top mesh panels (if applicable)
Isolation panels (if applicable)
Back-to-back panel configurations

They’re designed with high-quality materials and durable construction to ensure long-lasting performance, safety, and ease of maintenance—making them ideal for professional boarding facilities, breeders, shelters, and veterinary clinics.

Can I anchor them to concrete or grass?

Yes! TK Products kennels can be securely anchored to both concrete and grass. We offer anchoring kits designed for different surfaces to ensure your kennel stays stable and secure in any setup.

How long is your warranty?

Dog flaps

The fit is always very good but you’d expect that since they are OEM flaps. I wish they would include a metal or hard plastic bar across the top that would distribute the tension across the top. My dogs blast thru the door after squirrels and sooner than later one or more of the holes rip out and it’s not long after that the rest rip out and I have to spend another $100 to replace them
