18mm Solid Rod – Rodtech Click

Rodtech Click 18mm Solid Rod. Stiffer than the 15mm Rod. Therefore, ideal for use within flues 450mm and up. The rod is best suited to use in Large Open Fires and Inglenook Chimneys. When confronted by a large flue, such as an inglenook, you may wish to use this rod together with the Rodtech Click 18mm Aluminium Rod.

Naval Grade Brass for Complete Corrosion Resistance

Rodtech uses the highest quality materials in manufacturing their Rods. Including, UK sourced Naval grade Brass. For years, chimney sweeping equipment used brass due to its nonferrous properties. Rodtech proudly continues this tradition. Brass click ferrules are not susceptible to corrosion compared to Aluminium or stainless steel. Therefore, giving unrivalled longevity.

Rodtech Brass Click Lock (single button advanced locking system)

This patented design allows the use of a single button D-shaped Ferrule which does not rely on the button to keep the Rods connected. Instead, they lock together, remaining secure.
To disconnect the rods flick your wrist in the opposite direction that the rods were spinning. You will hear a “Click”, place the connected ferrules in the palm of a hand to take the weight off. Finally, use the free hand to press the button. 

Anti-Snag Ferrule

This unique design on all male ferrules prevents catching on any shelves or lips within the flue. Centrifugal force spins the Rod against the surface. The contours of this ferrule lift off the obstruction and continue down with no damage. A traditional rod is able to snag on the way down, and increase the risk of getting cut or damaged, especially when at maximum flexibility.

Temperature resistant Rods

Made from unique copolymer Rodtech Rods allow for extreme weather conditions without worry of failure. Designed to be fully functional at -35° maintaining their flexibility. Sterilization of the rods is possible if used on a bee’s nest and need cleaning.

Metre Length Rods

This is important for straightforward valuation as to the height of any obstruction within the flue.

Branded ferrules

Rodtech Ferrules are now Branded to show the customer that they have purchased the Ultimate Quality of Brass Click Rods.

Securely Crimped

Rodtech rods are machine crimped to secure the ferrule to the Rod without affecting the integrity of either material. Crimping is the most efficient way of manufacturing a rod as it leaves no protruding parts that could damage or catch in a liner.

Buttonless Drill Driver

Rodtech click technology can have no button on the drill driver to connect the rods while working from the fireplace/appliance. With the use of centrifugal force as the Rod spins, it will lock to the drill driver. To remove, stop the drill and slide the rod off, Saving time.
