"I was pleasantly surprised at the quality of these pipe collars, especially considering how cheap they were.
My only gripe is that the size is not stipulated anywhere in the Talon catalogue.....they are fairly large at 50mm diameter and on a small radiator look massive. Its a pity Talon don't offer a smaller option as well.
I can't rate the performance and reliability as I have only just fitted them, hence 3 stars only."
"The outside diameter of these collars are about 50mm; a bit bigger than some others on the market, which in my case was what I was looking for.
A bit more product information would be nice, Screwfix... These are "Polypropylene collars with Chrome effect coating" (quote from the Talon web site). Saying that - the outside diamater isn't even on Talon's site... These things are of interest to customers you know."
