When closing the spanner, a safety hook positively locks onto the body. This prevents the inadvertent or vibration-induced release from the clam- ping position. To open the safety hook it is unlocked per one-hand ope- ration. 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. see also... • General Information for Toggle Clamps → Page 698 • Square U-Bolts GN 951.1 → Page 774 Information 1 Size 2 Type 3 Material How to order (Stainless steel) 1 2 3 GN851.3-160-T6-A4 1 Size 2 Type How to order (Steel) 1 2 GN851.3-160-T6 2 Type T6 With square U-bolt, with catch T Without square U-bolt, with catch • Steel - - Case-hardened steel C10 Zinc plated, blue passivated - - Square U-bolt Steel St 37 Zinc plated, blue passivated • Stainless steel AISI 316L A4 Parts in sheet metal / Square U-bolt / Pin • All moving parts Lubricated with special grease • Handle with plastic cap Red, oil resistant • Stainless Steel Characteristics → Page 2166 • RoHS Specification 3 GN 851.3 Latch Type Toggle Clamps Steel / Stainless Steel with Safety Hook, with Pulling Action
