Tunnel Extender – 50mm

Description

The SureFlap Tunnel Extenders are fully compatible with OnlyCat and are used to extend the entrance of the cat flap – typically when fitting through a wall or a thick surface. Each tunnel extender adds 50 mm to the 70 mm tunnel of the cat flap, and several can be stacked to make a tunnel of any length. See our wall installation guide for details on how these are used.
