Used as a one piece system to secure the liner at the top of the stack. This product is mainly used where a clay pot is in situe (as there is no need to remove the pot to install). Simply slide the spigot of the cowl into the end of the liner and secure by tightening the smaller jubilee clip. Then, sit the cowl on the end of the pot and secure using the larger jubilee clip in the same way to the chimney pot itself.
Fits pots up to 305mm external diameter.
