Adjustable Wall Bracket for 6" Double Wall Chimney PipeThis adjustable wall bracket ensures the chimney pipe stack is firmly mounted to a wall or structure, with adjustable spacing from 2" to 7" to account for any architectural features that need to pass through the wall. The bracket keeps the chimney 2" away from combustible materials, and is recommended every 8' for optimal stability, though the bracket does not support the overall system weight.
