Information

Knee lever modules GN 810.12 have the same properties and attributes as the „Longlife“ GN 810.10/ GN 810.11 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.

These knee lever modules are therefore suitable for applications in which substantial forces occur and in which a long service life is required.

Extensive tests have shown that trouble-free function (under load) is ensured also after one million clamping cycles.

These knee lever modules permit the size and position of the lever and clamping arms to be adjusted to match the specific application.
