Information
GN 855 C-clamps feature an especially robust, sturdy and compact design, allowing them to be used under severe and demanding conditions, e.g. higher temperatures, dust, mist, etc.
These C-clamps are normally installed and mounted at the clamping point. The clamping plate (supplied loose) has a ball socket and is designed so it can attach to the surface area. In connection with the ball-ended screw this configuration ensures the precise positioning of the clamp.
If the clamping plate is not required, the clamping bracket socket can also accept GN 802 Toggle Clamp Spindle Assemblies, which include a swivel thrust pad that adjusts to slightly uneven surfaces.
