Applications

The channel washer HK is used for stable connections and to strengthen the FUS profile for fixing to the substrate.
Suitable for dry interior areas (standard HK 41).
Suitable for indoor and outdoor applications (HK 41 hdg, HK 41 A4).
HK 41 A4 is designed for environments with high stress to components due to corrosion.

Advantages

Provides a perfect connection with the FUS channel thanks to laterally curved contours.
The washer's shape facilitates quick and easy push-through installation of channel profiles.
Features fire resistance classification R120 and complies with German model pipeline system guideline MLAR R30.
