Rated 4 out of 5 by Capped chimney I bought two of these to stop water entering the property. They look good and are easy to fit. I would recommend attaching the straps before climbing on to the roof. Make sure you use roof ladders over the apex for maximum safety. 5 Oct 2015
Rated 5 out of 5 by Chimeny cowl Having suffered with rain getting down the chimney and into our woodburner, we decided to fit a cowl to the chimeny pot and remove the anti-bird wire basket we had in place. Having hunted around for something suitable, we came accross this item in screwfix and one was ordered for collection the following day from our local branch. It is very easy to install, if you don't mind heights and removing your hand from the ladder to fix! A sturdy jubilee clip fits around your pot's diameter and secures the cowl in place. It seems durable, well finished and will fit a wide variety of pot diameters. On ours it sits on top of the pot, but for those with a smaller diameter pot it will sit over it without any problem. All in all a good item at a reasonable price, that will keep the birds off and keep the majority of rain out too. 21 Dec 2012
