Connects directly to standard chimney pot. Fits 8-13" diameter pot. Anti bird/anti rain.
Bought to bird proof unused chimney, nice and sturdy, installer was impressed with quality. I ordered two in error and Stovefitters were happy to arrange a return and refund.
Bought an additional cowl so unused flue could be bird-proofed while my roofer was up putting in the flue liner for my stove. Looks to be a good quality item which looks like it will be up there for many years.
Just a basic cowl. Well made. Completely happy with it.
