Petsafe Staywell 900 Series Extension Tunnel

If your door or wall thickness exceeds the standard size for your pet door installation, worry not! Our convenient tunnel extension is here to facilitate easy access for your pet. Specifically designed to complement the Staywell® Classic Manual 4-Way Locking Cat Flap (919 Series), each extension adds 18 mm (3/4") of depth, ensuring a perfect fit for any setup. You can add a single extension or stack multiple to meet the needs of your specific door or wall thickness.

Please note, this extension is exclusively compatible with the Staywell® Classic Manual 4-Way Locking Cat Flap models 919SGIFD and 919EF, and it is not suitable for use with the 900 Series Staywell® Classic Magnetic 4-Way Locking Cat Flap.

**WARNING:**
Be advised that small children may be able to pass through the door. It is important to read the safety information thoroughly.
