SB Standard Model for Doors and Walls

The SB Standard Pet Door is our highest rated utility, economy pet door. They are made for doors 1 1/4" to 2" thick and our standard wall mount model fits walls 2" to 10" thick. This aluminum framed pet door features several attributes that sets it apart from other utility or lower priced pet doors.


  • Strongest Frame (aluminum)
  • Weatherized Flap Prevents Yellowing & Shrinking
  • Solid 1/4" HDPE Security Locking Panel - Most Secure
  • Door model fits 1 1/4" to 2" thick doors
  • Wall model fits 2" to 10" thick walls
  • Optional Grey or Brown Carpet

Each door has a slide-in Locking Security Panel that can be inserted to block off the pet door or completely removed to allow your pet access. This panel is made with 1/4" HDPE that provides more security than any other economy priced dog or pet door. Both Wall & Door models have the flap located on the exterior frame to maximize weather protection. Wall mount models include an aluminum tunnel which measures 10", making it suitable for wall depths of 10" or less, with optional grey or brown carpet. These pet doors are offered in WHITE or BRONZE (Dark Brown) powder coated frames. The Security Panel comes in white.
