The PetSafe Electronic Pet Door Wall Conversion Kit offers pet parents an easy way to expand the placement of their electronic pet doors, allowing them to install in a variety of wall types while maintaining reliable performance and durability. This conversion kit is specifically designed for use in traditional framing and drywall construction, such as 2x4 or 2x6 walls, making it simple to add safe pet access in more locations throughout your home. For brick installations, the outdoor cutout is recessed to fit the frame securely, giving you more versatility for both indoor and outdoor placement. With this kit, small electronic pet doors can be installed in walls up to 8 inches thick, while large doors can fit walls up to 7 1/4 inches. For even thicker walls, extension tunnels are available separately, each adding 2 3/4 inches to the depth. The telescoping design makes adjustments quick and straightforward, giving you the ability to create a custom fit wall passage that matches the specific dimensions of your home. The durable construction ensures lasting performance while maintaining the security of your electronic pet door, so your furry family member can move freely between spaces while you enjoy peace of mind.
