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: 
Fits any style of door from flat surfaced to panel designs and irregular surfaces.  Door sandwiches opening from both sides ensuring a tight fit on any surface. 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.

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.

Superb July 14, 2009
Reviewer: Jedediah from Utah,  United States  
This is an excellent door. Quality at its finest. Thick enough flaps to keep the elements out, easy enough for my dog to access easily. I will never get another dog door for as long as I live. Superb!

Worth every penny June 17, 2009
Reviewer: Candy from Missouri   
After months of constantly replacing flaps and having cold air leak in through my old Petsafe door I decided it was time to invest in a quality pet door.  I did my research and was throughly impressed with this Maxseal door.  After making sure they had a return policy I purchased the door and have never been happier.  The door seals great and the flap is super durable and does not even show use yet.  Thank you MoorePet!

I'm glad I called August 1, 2007
Reviewer: Kim from Allenspark, CO    
I was on the website and I couldn't find the same door that I'd ordered from you in the past, so I called you and boy am I glad.  Turns out, the door I bought a couple years ago is no longer available so the male I spoke with suggested this door and it's worked out great.  Thanks!
