Stone Age Chimney Offset Blocks create clearance when required by shifting the chimney away from obstructions such as beams or floor joists that may be directly over the fireplace, or other applications where the chimney may need to routed at an angle. Offsets create 6 inches of offset per 12 inches of rise, and may be installed in a spiral or twisted configuration if needed.
