The The MaxSeal single flap pet door has a flap on the very exterior frame to provide weather protection. Single flap doors are often used in situations where an insulating barrier to the outside is not the main concern. These doors will keep out bugs etc. and provide you with a better seal than any other single flap 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.

Security Boss Manufacturing LLC is dedicated to providing products that operate beyond expectations
and provide the customer with long years of satisfaction.
Our products are designed so that you can maintain your pet door indefinitely.

Great Insulating Pet Door April 2, 2010
Reviewer: A.R. from Fargo ND, United States  
I purchased a MaxSeal dog door last Fall in preparation for the cold weather here in North Dakota.  I have 3 Labs that use the pet door incessantly.  I more than pleased with the performance of this doggie door!  I have already told two of my friends and they have since ordered.  Great product, great design.  Thank you for a quality product.

MaxSeal July 1, 2009
Reviewer: Jessica M. from ,  United States  
I just received the door a week ago and already love it!  I was able to choose the colors I wanted and it looks great in my wall.  Above all, the flaps actually stay closed and keep the wind out!  Amazing product, Thanks.

Goodbye breeze June 25, 2009
Reviewer: Julius from Moorehead,  United States  
Maxseal=no breeze, anything else=high energy bill! I am so glad I got this door. I can barely even tell there is a dog door in my wall. Thank you for making such a great door!

No More Draft June 23, 2009
Reviewer: Mark from South Carolina  
I used to have a constant draft in my house from low quality dog doors I purchased at the store.  Ever since I got the Maxseal the draft has disappeared and my energy bill has decreased very noticeably.  I only wish I had found this door sooner.  Thanks!
