AWENTA Ø 4" To 6" Round Ventilation Grille, White Plastic, Fiberglass Net, Exhaust Air Grille, Supply Or Exhaust Air Grille - Adjustable Air Duct Size - External Dimensions Ø 7" - White

I needed an internal grille for a 6inch air con hose and this proved to be good value. The internal mounts are easy to adjust and grip the inside of the ducting fairly well.The inner most part only attaches to the outer grille with friction push fits so I ended up glueing these parts together as they came apart too easily hence the 4 stars. I also wasn't really sure how to make the grille sit flush to the wall so I used a few dabs of hot glue to secure it to the wall. It's a good directional grille allowing me to direct the warm air out of the open doors on the roof.

Great little vent - needed to cover a pre-existing hole in a garage wall after it had some general improvements. The adjustability is the feature I was after, as the hole in the wall (made by the previous home owners for a tumble drier vent) did not seem to be any kind of standard fit.The inner fitting bracket is simple to fix to the wall (trust me, I’m no more than an occasional DIYer), and then the fascia section just clicks onto that. Between the two layers is a simple but effective sheet of mesh for use to prevent insects etc.It has done exactly what was required - it could possibly benefit from a more positive ‘connection’ when you push the fascia onto the backing plate, but I’m splitting hairs, as they are connected. Once in place it would be very easy to apply a silicone seal around the edge to make it look super tidy, but for me, i would prefer the ease of being able to remove it every now and then to keep the fascia and the hole it covers free from any dirt, dust, spiders webs/eggs etc.I can happily recommend this grille

This item was bought to fill an modestly sized and irregular hole in a plasterboard ceiling following and emergency plumbing repair in the void.The vent has four sliding plastic arcs with ratchet fastening.Pop off the louvered cover to leave the frame.Put the sliding arcs into the middleOffer the frame up to the holeSlide out the arcs until they are tight.Pop the cover on.Brilliant!Lightweight. Pure white and incredibly fast.Highly recommended

This vent is good for attaching to air conditioner exhausts which have a specific size not commonly found on one size vents. It can adjust from 100mm to 150mm big (on the inside), to attach to any hose approximately in the size range. However, it does feel quite flimsy when connecting the hose, and feels like it could snap. I would recommend getting a stronger one to anyone who knows the exact size of the hoze that they have. Again, it does the job for me, hence the four stars.

Brilliant. Have bought the chrome version also, used to provide easy ventilation in my hallway, and cover an access hole I had to make for a junction box in our downstairs loo. Fully adjustable across the range of hole sizes stated and fitted in seconds. Excellent value.
