Review: Having had a traditional louvre duct cover which the flaps were in the habit of getting stuck open I purchased this item having read the reviews. The cover looks very neat however I wanted to echo some of the comments made in other reviews. The cover doesn’t come with any screws – not a problem I thought as I have a number – however the pre-drilled holes are very small so even for the screws I had it was a challenge finding ones suitable The internal plate to prevent back draft has lugs on either side at the top to slot into some pre-drilled holes – in truth it took me a while to get it in position as in my opinion the lugs are a little on the short side – but I managed in the end. I noticed others said about affixing a nut to the plate to add extra weight and prevent it rattling – I didn’t but with the intermittent rattling I will do so. The tip by another reviewer about sealant around the outside was a good suggestion and gives a nice finish Overall it looks good and does the job – and is (will be) better than the previous louvre fitting I had Review: Produit conforme à la description. Livraison plus R rapide apidé que prévue. La qualité est correcte à voir la tenus dans le temps.
