The 1m Sit 1872 chimney wire extension is ideal for cleaning round fireplace chimneys. Made of metal material, it offers durability and effectiveness in removing combustion residues. It is designed to facilitate access and cleaning even in the most difficult corners. Its use is simple: connect it with a rope and move it up and down to clean the walls of the chimney. It is suitable for built-in chimneys, which accumulate more residues than metal ones, ensuring that your chimney remains functional and safe.
