The MaxSeal dual flap pet door has a flap on the interior and the exterior frame creating an insulating air chamber. This works so effectively due to the flaps sealing perfectly every time; no bugs, drafts or leaking. The MaxSeal Dual flap pet door is the most energy efficient pet door made.

Easiest to Install: 
Your pet door tunnel is easy to trim with a pair of tin snips so that you get a perfectly sized tunnel for your wall, no seams, or weakness as found in tunnel kits. The door comes nearly fully assembled when you receive it. The tunnel is already riveted to the interior frame. After cutting your hole through the wall, sleeve the tunnel through, mark it, then trim to fit your wall fitness for a custom fit. The exterior frame then sleeves into the tunnel from the outside and secured with screws. Trim the tunnel carpeting to fit. The MaxSeal is not your average lightweight aluminum door, but a quality made accessory for your home. Function, security and customer satisfaction is what drives the people at Security Boss.

-Best sealing flaps compared to any other brand
-Flaps are compliant with the California State Fire Marshall
-Nylon reinforced flaps for optimal strength and durability
-Flaps are "Weatherized" to eliminate any shrinking in hot and cold environments
-Easy thumb-screw flap attachment for quick flap replacement (no dis-assembly of pet door required)
-UV resistant - prevents yellowing and cracking
-Will stay flexible in temps in excess of -40 degrees
-Impact tested in -40 degree conditions
(If it's that cold out, do your pet a favor and lock off the door with our insulated security panel).

Insulated Security Panel:
More secure, durable and impact resistant than all other models. The only insulated security panel on the market!  1/2" thick hollow air channel center with reinforced side panels. This security panel is the most rugged, locking panel in the industry, when this pet door is locked, no one can get in. The MaxSeal is the only pet door that we recommend as truly being secure.

Solid Tunnel: Comes with standard 10" tunnel, optional 16" available for thicker walls. Trim-to-Fit for any wall thickness, 2x4 or 2x6 stud framed. Use the 16" for thicker walls such as 2x6 with brick exterior, cinder block, even log homes.

Tunnel Carpet: No slip, indoor/outdoor carpeting included to line your tunnel. Nylon fiber, stain resistant, easy to secure with silicone.

Magnetic flap Closure:
Flap has positive closure with alnico magnets (More expensive but seals the flap perfectly).  These flaps seal perfectly every time your pet uses the door. Magnets on sides of flap as well as bottom. You will not have any creepy crawlies entering your home when you use MaxSeal.

Insulating Brush Seal:
High density brush pile material lines the flaps so that there are no gaps. This pile brush is easily replaceable and inexpensive so that you can always maintain the optimal performance of your door.

Custom Hardware:
Fold down handle and retractable dead-bolt pin for maximum security. Security Boss does not use cheap window hardware, but quality, aesthetic components.

Customize Security Panel Entry:
The security panel comes standard loading from the top. If you have an obstacle above the pet door such as a window sill, you can order your door with the security panel loading from either side. There is no extra cost and no extra time to fulfill your order.

Color Options:
Broad range of color choices to fit your home. 10 various frame colors that feature our powder coated finish. You also can choose between white or black for your security panel to compliment your door.

Durable Door May 22, 2013
Reviewer: Gregg from NE  
I looked all over for a door that would withstand my Irish Wolfhounds abuse and bought one locally. That "perfect pet" door didn't last a week against my dogs, but I think it was just too small. This size is perfect and very durable. I highly recommend this Maxseal pet door.

I Highly Recommend MaxSeal Wall Mount Dog Door March 26, 2011
Reviewer: Augusta C. from Galway, NY United States  
I read all reviews before I purchased dog door and found them all helpful. I wanted to wait to write my review, I wanted to see how the winter weather would treat the door. I purchased and installed (very easy to install!) dog door back in Oct.2010. It has been worth every penny! My 2 St.Bernards now have the freedom to come in and go out when they want. The inside flap did have frost on the bottom at times, but it was below zero out! The carpet that came with wall mount did not cover all inside of tunnel like video showed so I went to local store and purchased a piece of outdoor carpet, easy fix. I am VERY PLEASED with this wall mount dog door and would definitely recommend for larger dogs.

Fantastic! July 27, 2009
Reviewer: Katie from Wyoming  
Despite this door's massive size it still seals great.  I never would of thought a pet door that worked this well would be available in such a large size.  Thank you Moorepet!

GREAT DOOR July 16, 2009
Reviewer: Martin G. from el monte CA,  United States  
Thanks for the great door Moorepet!  I wasnt sure if I would ever find a door large enough for my Mastiff.  This door is amazing! Big enough for charlie yet still energy efficient.  I recommend to anyone looking for a quality pet door! Thanks again!
