This kit, set on the runner of rails E53 and ST53, repels out of the raceways large impurities which could block the movement.

It is composed of two plastic wipers. They are held at each end of the runner by an anodized aluminum plate. The plate increases the runner thickness of 5mm. The wipers increase the length of 20mm.

It comes pre-assembled on the runner. The delivered screws have to be replaced during the final fixing of your installation.
