The clamps will lock securely over the centre and are thus vibration proof. The stroke w 1 of the clamping hook can pull the parts to be clamped to- gether by up to 6 mm. The range w 2 can be adjusted on the M6 threaded spindle at the clamping hook. The types S, SV and SS prevent unwanted release of the toggle latch. In the standard version the toggle latches of type SS have the same lock and / or the same key. The load specified in the table are simply guide line values for a nominal static pulling force which the lock can withstand. Depending on the con- ditions under which these toggle latches are used such as vibration or shock loads, the holding capacity can be adversely affected. The catch bracket is included. see also... • Horizontal Latch Type Toggle Clamps GN 851 → Page 756 Information • Steel ST Zinc plated, blue passivated • Stainless steel NI Only type A, S and SV - - Parts in sheet metal AISI 304 - - Clamping hook / pin AISI 303 • Stainless Steel Characteristics → Page 2166 • RoHS Specification 3 2 Type A Without safety catch S With safety catch SV For safety catch with padlock SS With key lock
