Set Contains: SureFlap Cat Flap Tunnel Extender 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: Works great with the Sureflap Door! - I recently installed the Sureflap Cat door going from my house out to my garage, These tunnel extenders were perfect! They hold up well and connect easily. ## Features - COMPATIBILITY: Works with SureFlap Microchip Cat Flap, SureFlap DualScan Microchip Cat Flap and SureFlap Microchip Cat Flap Connect. - EXTRA EXTENSION: Adds and extra 50mm to the 70mm tunnel of the cat flap. - EASY TO USE: Fits snugly onto the cat flap tunnel. - EASY TO INSTALL: Made of plastic and doesn't require any additional tools to install. - CUSTOMISATION: Simply stack multiple extenders together to create the required tunnel length. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B003HK9IIK | | Brand | SureFlap | | Brand Name | SureFlap | | Closure Type | Magnetic | | Color | White | | Colour | White | | Customer Reviews | 4.5 out of 5 stars 1,285 Reviews | | Frame Material | Plastic | | Global Trade Identification Number | 05060180390174 | | Item Type Name | Cat Flap Accessory | | Item Weight | 0.15 Pounds | | Manufacturer | Sure petcare | | Manufacturer Part Number | Tunnel Extender - White | | Material | Plastic | | Material Type | Plastic | | Mattress thickness | 0.5 Feet | | Maximum Compatible Thickness | 0.5 Feet | | Minimum Compatible Thickness | 0.5 Feet | | Minimum compatible thickness | 0.5 Feet | | Model Number | Tunnel Extender - White | | Number of Items | 1 | | Pet Type | Cat | | Size | 50mm | | Target Audience | Cats | | UPC | 812472020048 | | Unit Count | 120 Grams | ## Product Details - **Size:** 50mm - **Brand:** SureFlap - **Colour:** White - **Material:** Plastic - **Mattress thickness:** 0.5 Feet ## Images ![Sure Petcare Microchip Cat Flap Tunnel Extender, Compatible with SureFlap Cat Flap, DualScan Microchip Cat Flap & Cat Flap Connect, White - Image 1](https://m.media-amazon.com/images/I/61DBdrtDX8L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Cutting second tunnel may be required. *by P***. on 2 May 2021* Worked as expected.
