Tunnel Extender

SureFlap tunnel extenders can be used when installing SureFlap^TM in a wall.  Each tunnel extender adds 50mm (2") to the length of the tunnel and the tunnel extenders can be stacked together to create a tunnel of any length.  SureFlap's existing tunnel is 70mm (2.75") long. 

PLEASE NOTE: the Tunnel Extenders are a special order and can take longer to be delivered.  If you need them by a specific date please contact Customer Services for more information.
