This is a standard size basket thing to go over the flue outlet for your gasboiler. This is brilliant as it doesn't rust like my previous one, which dripped rusty stains all over the gas meter box underneath. I don't need it any more as we now have an airsource heatpump, not a gas boiler.
I don't have a smart phone so may not reply straight away.
