DescriptionRodtech Click 18mm Aluminium Rod.
These 18mm Aluminium rods are perfect for flues and ducting with a range of sizes upwards of 600mm.
When confronted by a large flue, such as an inglenook, (600 mm and above) you may wish to use this rod with the 18mm Solid Rod. It is advisable to use a solid rod as a leader rod. Alternating the solid and aluminium rods gives the entire length a small amount of flexibility.
