Map Aluminium Adjustable Air Vent for Openings 9" x 6" (229mm x 152mm), Double Brick Hit & Miss Ventilation Metal Cover, Silver

Simple design, works well, easy to fit . The front grill easily slides shut or we can keep open depending on the weatherWe added a thin backing to fully seal it against the exterior wall airbricks. The airbrick is in a stone wall so our seal was used to make sure there were no gaps at the edges.We have only just put it on so will let you know how it goes over the next few months

Good quality, competitive price, better than just the white plastic versions

Fitted easily is made from thin aluminium so will bend or dent during fitting, needs care. Works well and look good.

Accurate size guide which enabled me to purchase the correct one.Good quality and value for money, easy to use and install.

Good quality for the price

There not bad and do the job, not the greatest of quality feeling to them, but they do the job and stand up to weathering well

These are so flimsy and thin. After installing them I noticed gaps all around the edges because the screws just hold in the area around them and not the actual unit itself, akin to paper on a notice board.

Liked this very much but found it dripped condensation when the weather went down to 0 degrees.So had to replace it with plastic one.
