Manrose White Rectangular Adjustable vent & Fly screen, (H)76mm (W)229mm

It is aplastic vent, what do you expect, easy to work, you cannot put in place upside down!!!!

I bought these to replace old plaster type ones and they worked a treat a lot slimmer to the wall and looks good

They're pretty good, but if you want to cover a wider vent by placing some end to end, you need to cut one end off the sliding cover, because it has a lip all the way around that overlaps the back plate. It's not an easy thing to cut neatly.

You'll then also need to stop it sliding all the way off - I used a short screw, from the back.

For weeks I felt a draft, the air vent did not have a fly screen so was open all the time, this one with the fly screen has solved the problem and is great
