Regular chimney sweeping keeps a fireplace burning efficiently, and this kit's nylon rod extends to 23 feet (7 meters), enough to clear a typical square or rectangular flue from the firebox in one session. The rod flexes past 90 degrees to follow bends without jamming, and the rectangular aluminum alloy brush head with strong nylon bristles lifts soot and creosote from the flue walls without scraping the liner. A plastic swivel connector keeps your hands off the spinning rod while you sweep from the bottom up, and the spring-button locking system joins rod sections securely in either turning direction, so more sections can be added if the chimney runs longer than expected. At 4.19 pounds (1.9 kg) it's light enough for one person to carry and use, and the kit includes spare bristle heads and goggles so you're fully equipped.
