Stainless steel latch type toggle clamps GN 851.3 are compact in design and can be used to ensure high holding capacities.

When closing the spanner, a safety hook positively locks onto the body. This prevents the inadvertent or vibration-induced release from the clamping position. To open the safety hook it is unlocked per one-hand operation.

The square U-bolt can be adjusted within its range.

In addition to the standard lengths of square U-bolts shown in the table, a variety of other lengths are also available under the GN 951.1 series.
