SureFlap Microchip Large Pet Door
The SureFlap Microchip Large Pet Door Tunnel Extensions
can be incrementally added to fit any wall depth. Each SureFlap pet door extension measures 2" in thickness. The Sureflap Microchip Pet Door can fit thickness's up to 2 3/4" without any extensions. Measure your complete wall depth and subtract 2 3/4" from this measurement to determine the number of extensions you will need to add to the SureFlap in order to fit your wall depth. (if you have a 8" thick wall, you will need 3 additional tunnel extensions). The SureFlap tunnel extensions are available in white only.
Note: These tunnel extensions will only work with the SureFlap MicroChip Large Pet Door
Optional SureFlap 2" thick tunnel extensions for use when installing the SureFlap Microchip Large Pet Door through a wall.
