What size screws will I need for the plain white 100mm version? Screws on previous one are thicker. Also, does the outside clip off for cleaning?

I was lucky as it was a replacement and I could use the old screws. They were about number 4 by 1/2 inch plated, or brass as there is moisture. The cover does clip off but it is a "good fit" and you would risk damageing it. It also becomes more brittle with age. Mine was in situ about 20 years and only realy needed replacing as the bathroom was refitted and it was a white suite so it showed up as needing renewing due to it becoming an off whiteshade.

Silly question, is the mesh screen optional or must they be fitted

Hi, No question is a silly question! The mesh comes pre-installed on all our Fixed Blade models. If you wish to remove it, you can. Kind regards, The Ventilation Shop

Cheap & Cheerful

Good price and decent build quality. Works as intended. However, it's not a great fit for the inside diameter of a solid vent pipe - too loose and no spring clips. Also, there's no fixings supplied, and the screw fixing positions aren't standard - only a problem if you're looking to replace an existing grill, as you'll need to drill new. Flaps open and close, so it does the job.

Good quality

This looked perfect for what I ordered it for but unfortunately I ordered the wrong size so had to return it. No issues with seller and got my full refund quickly.

Vent outer wall cover

Flap doesn’t quite close properly when screwed to wall, due to screw head rising slightly higher then plastic body. But still good value reduced wind back flow by about 80%.
