6-Inch Wall Thimble Kit with Finishing Collar (Through-Wall)

Passing a hot chimney pipe through a combustible wall requires a certified safety system. This 6-Inch Wall Thimble Kit telescopes to fit standard wall thicknesses, maintaining the required 2-inch air clearance to wood framing. Unlike basic kits, ours includes a matching finishing collar to cover the gap on the interior, providing a clean, professional look for your stove installation.
