Information
GN 910.3 heavy duty knee lever modules have the same properties and attributes as the "longlife" GN 910 and GN 910.1 vertical toggle clamps. The clamping arms are die-forged, the remaining steel sheet parts have been reinforced, and bearing pins and rivets are hardened and ground.
Therefore these clamps are suitable for applications in which substantial forces occur and a long service life is required.
During extensive testing, with trouble free function and under load, the clamp has withstood over one million opening and closing cycles.
These knee lever modules permit the size and position of the lever and clamping arms to be adjusted to match the specific application. The actual module is welded on.
