Information
GN 852.3 latch type toggle clamps are compact in design and can be used to ensure high holding capacities.
The circular movement of the handle is transformed into linear action of the latch.
In the clamped position the U-bolt latch with clamping arm is parallel to the plane of the operating handle.
When the toggle clamp is clamped, a safety hook positively locks onto the body. This prevents inadvertent or vibration-induced release from the clamping position. Unlocking of the safety hook is achieved by one-hand operation.
The stroke of the U-bolt latch of these toggle clamps can be adjusted within its range.

In addition to the standard lengths of the U-bolt latch shown in the table, a variety of other lengths are also available under the GN 951.1 Square U-Bolts series.
Also available in stainless steel series GN 852.3.
