Fast & Simple retrofit installation with extendable reach and a telescopic shaft to get the magnet to the most effective area. Features a chrome end cap with an integral bleed nipple for easy system checking. This filter is easy to fit with minimal tools and can be removed and cleaned within seconds. It fits most standard towel warmer radiators and is designed to last as long as the radiator is in use. Enjoy zero plastic packaging, as all components are 100% recyclable at the end of their life.
