SB72 | Insulating Dog Door for Doors

Dog Doors

The SB72 is a more durable, rugged version of the popular MaxSeal pet doors by Security Boss. They are the best sealing and insulating doors on the market, as well as the most secure when locked. These are the best pet doors by design. Only the finest materials are use in the manufacture of these doors by Security Boss Manufacturing LLC. The SB72 is designed to be maintained forever. This is the last pet door you will need to purchase for your dog. All components are manufactured so that the customer can easily replace, upgrade, or maintain all the main components. The structural integrity of the door and security panel are protected under warranty so that you will always have a superior performing product for the life of your dog.

This model features an insulated rigid flap that is clad on both sides with aluminum and reinforced with rugged aluminum framing channel. The quiet swing action makes this ideal for use in your home. The exterior flap has been designed to perform in harsh or extreme environments. The door components are all high grade aluminum that is naturally rust resistant. The heavy duty internal hinge is stainless steel, housed in custom brass bushings. Our insulated flap is comprised of an inner polycarbonate, air cell center that is clad in aluminum, and reinforced with customized framing on all sides. Embedded rare earth magnets along the bottom of the flap and bottom framing align to provide for positive closing every time. Replaceable weather stripping lines all sides of the swing door frame. The swing motion of the door is easy to use by dogs of all sizes and settles into place... silently.

Who Uses the SB72 Models?

The SB72 was designed specifically for two groups of customers:

1. Customers who lock their dogs OUTSIDE and have experienced chewing problems

2. Customers living in the extreme northern climates where temperatures fall below -40 degrees Fahrenheit.

Security Boss is setting the standard for pet doors in terms of pet door quality. Customers can customize their door with several options that make each pet door unique for their home. Whether it be the direction the security panel loads, the color options, high wind accessory magnets for very challenging environments or the option to get a door that will accommodate an aging pet with arthritis, Security Boss offers our customers the most flexibility and the best performing product in the shortest amount of time.
