8" Selkirk 24" Support Box - 208424

The Support Box is intended for use when installing chimney in an A-frame, in a mobile home or in a ceiling under a narrow section of roof. It provides a finished installation at the ceiling level and will support up to 20' of 8" diameter chimney.

Engineered for safety, Selkirk, also known as MetalBest or MetalBestos, chimneys are packed with one inch of premium fiber insulation, ensuring a 100% fill. This superior insulation maintains higher internal flue temperatures, enhancing draft and efficiency. Low temperatures are maintained on the outer casing, allowing installation as close as 2" from combustible materials. Assembled with the Positive Joint Coupler, the safest and most secure locking system in the industry, Ultra-Temp and Galva-Temp chimney sections twist together with a 1/8 turn. A locking band ensures system integrity and strength for the life of the chimney. Selkirk again sets the industry standard.

Note: This Selkirk pipe can be used in Canada but ONLY FOR GAS AND OIL.
