Review: Perfect fit, Just the Job - Fast delivery (arrived before the cat flap from another source). Fitted easily and perfectly. Just big enough along with the cat flap to fit in a single brick wall. Very pleased with the result. I do wish however, I could have got this in brown to match the cat flap.
Review: £7.95 and £4 minimum to send back-!!-as wasn't required after all. - Great item-but we found it was not required after all-so selling on a well-known auction site as this would cost over half what I paid to send it back with desertcart-which is rubbish-!! **Be warned** tho'-no way could you cut this (or the matching cat flap) with a Stanley knife as shown on instructions-!!-it is way too thick-and you could severely injure yourself-!!-we ended up using a hacksaw/saw blade-and it was tough enough-!!

## Questions & Answers

**Q: Can this be cut down to fit a door 58mm thick?**
A: Yes you can cut the loner as shallow as you need...I used a Dremel or you could use a fine saw. Would have thought if just a door to go through no liner would be necessary.

**Q: Is this compatible with the 221w?**
A: Pretty sure it should say on the cat flap which can fit the tunnel/wall linner. From memory there were 2 cat mate flaps it fitted but think they were higher numbers than 221w.

**Q: product dimension 22.9 is larger than size of recommended cat flap 235W to go with it.  What are internal and external dimensions of this cat flap?**
A: I found no problems using this liner with the 235W.  They are compatible.  The 22.9 figure is a diagonal measurement, the real internal size is approximately 16cm wide by 16.5cm high.

**Q: What is this for please?**
A: This item is designed to bridge the gap between the flap section and the other part when fitting the flap through (say) a 4 inch thick stud wall. Or, also a single brick wall or similar thickness exterior door.  It can be trimmed thinner if the door is not too thick, or if the two parts do not quite reach through the item you wish to install the flap and outer flange into.

### ⭐⭐⭐⭐⭐ Perfect fit, Just the Job
*by P***E on 16 November 2013*

Fast delivery (arrived before the cat flap from another source). Fitted easily and perfectly. Just big enough along with the cat flap to fit in a single brick wall. Very pleased with the result. I do wish however, I could have got this in brown to match the cat flap.

### ⭐⭐⭐⭐ £7.95 and £4 minimum to send back-!!-as wasn't required after all.
*by A***D on 2 January 2021*

Great item-but we found it was not required after all-so selling on a well-known auction site as this would cost over half what I paid to send it back with Amazon-which is rubbish-!! **Be warned** tho'-no way could you cut this (or the matching cat flap) with a Stanley knife as shown on instructions-!!-it is way too thick-and you could severely injure yourself-!!-we ended up using a hacksaw/saw blade-and it was tough enough-!!

### ⭐⭐⭐⭐⭐ Expensive but do the job - I had to buy 4!
*by S***Y on 14 May 2020*

I bought this together with the catflap. It was difficult to calculate how many tunnel pieces I need as this was going in a 9” solid wall. I bough 4 tunnels which clip together, these ended up costing more than the catflap itself. The tunnels are expensive for what they are but do the job nicely and being plastic can easily be cleaned.
