Security Boss Standard Dual Flap Door Mount Pet Door - Large (13" x 20")

The SB Standard Pet Door for Walls is Security Boss’s highest-rated utility pet door, designed for walls 2" to 10" thick. Hand-built to order, this economy-friendly model combines durability, security, and ease of installation—making it the best choice in its class.

Crafted with a powder-coated aluminum frame (available in White or Bronze), the SB Standard includes a ¼" slide-in Locking Security Panel that inserts from the top. This panel offers more security than any other utility pet door, giving you the flexibility to allow pet access or completely block off the door when needed.

Each pet door comes with a 10" aluminum tunnel, designed to fit most wall depths and easily trimmed to size with tin snips. For added comfort, you can choose an optional carpeted interior (grey or brown). The weatherized flap is mounted on the exterior frame, maximizing insulation and protection against outdoor elements.
