About This

EASY WALL INSTALLATION: These 50mm (2”) sections can be added to specific products, allowing for seamless installation through walls or thicker door panels

COMPATIBILITY: Works with a range of cat flaps, including Closer Pets Large Cat Flap, Cat Mate Large Cat Flaps, and Cat Mate Large Glass Fitting Cat Flap
