GN 801 clamp mounts have been developed for use with toggle clamps that are designed with a forked clamping arm.
The clamp mounts can be moved along the clamping arm. Once the desired position is reached, you can secure the mount in place with the clamping screw.
The thread d2 serves to hold the wide variety of toggle clamp spindle assemblies, spring elements and similar devices.
The ideal clamping height can be adjusted without loosening the clamp mount on the forked clamping arm.
