Engineered for taller masonry chimneys and multi-story prefab stacks, this 39 ft. / 12 m sweep kit lets homeowners tackle annual maintenance without renting equipment or scheduling a chimney sweep visit. Modular fiber-reinforced nylon rods snap together with positive spring-button couplers that lock firmly whether you spin them by hand or run them from a cordless drill, while an insulated plastic swivel keeps your grip safely separated from the rotating shaft. The upgraded aluminum alloy brush head wears hardened nylon bristles in a sharp profile that scrubs creosote, soot, and small debris out of square, rectangular, and round flue runs without scratching glazed clay tile or stainless steel liners. The rods bend past 90° to follow chimney elbows, dampers, and offset stacks, then return straight for the next pass, and the assembly breaks down to a tidy bundle for closet storage between burning seasons. Replacement bristles ship in the kit so the brush stays effective over multiple sweep cycles, and impact-rated safety goggles round out the package. Exterior. Material: Nylon. Length: 39 ft. / 12 m. Item Model: AS12.
