Sure Flap Pet Door Tunnel Extender White

Pet Door Tunnel Extender For wall installations, tunnel extenders can be stacked together to create a longer approach tunnel to the SureFlap Microchip Pet Door or the Microchip Pet Door Connect when it is installed in a wall. The Pet Door Tunnel Extender fits snugly onto the 70mm long tunnel of our pet door. Each tunnel extender adds 50mm to the overall length of the tunnel.
