## Overview

The SureFlap Cat Flap Tunnel Extender is a 2-inch long, stackable plastic tunnel designed exclusively for wall installations with the SureFlap Microchip Cat Flap. Lightweight and easy to install, it allows you to customize tunnel length by bonding multiple extenders, enhancing your cat’s access and outdoor viewing experience.

## Description

The tunnel extender is compatible with the SureFlap Microchip Cat Flap and is specifically for wall installations. The tunnel extender is 2" in length and multiple extenders can be bonded together to form a tunnel to meet your requirements.

Review: Cutting second tunnel may be required. - Worked as expected. I went through outside R/R siding, and inside 5/8 sheetrock. Did not need instruction, but did read what was there. That info is sufficient. Frame-out wall cavity. The long screws provide will not reach through to secure two sides of unit together. Also, the plastic tunnel is soft. Better to have that rest on a wood base. Framing not a problem if you have normal 2 X 4 studded wall. (Use 2 X 4.) I needed two tunnels to achieve proper outside overhang. This required taking nearly an inch off the second tunnel. Not a problem using 1" X 30" belt sander. Mark your cut with masking tape. Take your time. Don't get burnt.
Review: SureFlap Tunnel Extender works! - SureFlap tunnel extender was just what we needed when adding insulation to the wall where the SureFlap pet door was already installed. Our kitty just has 2 more inches of tunnel to travel, and more time to look outside before she leaps. Easy to install, arrived on time and in perfect condition.

### ⭐⭐⭐⭐ Worth the wait!
*by J***E on August 29, 2025*

The only problem with this was it was sold out and it a little while for me to get it. Once I did, it works great, it made my life so much easier having the dog door! I used some outdoor sealant around the edges just to be overly cautious, but it fit right into the hole and the dogs loving coming and going.
