Frequently Asked Questions

The W-CDTW fits panels between 11mm and 52mm thick, covering a wide range of timber, composite, metal and uPVC door types. For thinner panels up to 30mm, the slim line W-CDW is also available.
No: the W-CDTW features a unique self-adjusting tunnel design that requires no cutting of the tunnel liner. It automatically accommodates panels from 11mm to 52mm thick, making installation straightforward for any panel in that range.
The W-CDTW has a usable opening of 155mm wide × 157mm high, suited to average-sized cats up to about 7kg. Measure your cat standing at its widest point and its body depth (top of the back to the bottom of the chest) and add 25mm to each; if either figure exceeds the opening, or your cat is 7–10kg (Maine Coons, for example), choose the wood fitting maxi pet door with its 180 × 227mm opening. Use our Pet Door Selector for a personalised recommendation.
Yes: the W-CDTW is designed for DIY installation and includes a cutting template. No glazier is required. The self-adjusting tunnel fits any panel within the 11–52mm range without modification. Full instructions are included and available to download above.

The inner frame projects 11.5mm and the outer frame 9.5mm from the panel face. The flap-to-body gap is machined to a near-zero tolerance and finished with a full brush seal, so there is no daylight around the flap for a draught to use.
