Add the finishing touch to your wood stove installation project with this Imperial Stove Pipe Trim Collar. Designed to be installed on the wall where stove pipe connects to the chimney, the trim collar covers the excess open area to provide a decorative, finished look. The pipe collar is constructed with 24-gauge cold-rolled steel for strength and durability, and it has a black matt painted surface that is resistant to chipping and scratching. Easy to install, the single-wall stove pipe trim collar is suitable for use with 7-in round stove pipe and fittings.
