The SB Standard Patio Pet Door by Security Boss Manufacturing LLC combines both the function and aesthetics that are lacking in current utility patio inserts. There are 4 height ranges that will fit all sliding door heights. The top of the SB Standard has an adjustable spring loaded top that can be locked-down for security. Locking the top will prevent someone from compressing the top from the outside and gaining access to your home.

The top of the Security Boss Patio Inserts are specially designed for the addition of snap on extensions that lock tight when in place. Each extension adds 2 inches to the overall patio insert height. Adding two will result in an overall height adjustment range of 7.25 inches. These extensions are rock solid when snapped together and require NO TOOLS or DRILLING.

The SB Standard Utility Pet Door comes in 4 sizes with each offering various step over rise heights you can choose from. This will elevate the chosen pet door size to the proper height so your pet(s) can easily step through the opening while still not hitting the top of the pet opening.

These inserts are made for every height option from 70″ to 99″.
