Properties and application:
- Hook clamps GN 821 are used among others for the secure holding of flaps and container lids
- The clamps will lock securely over the centre and are thus vibration proof
- The stroke w1 of the clamping hook can pull the parts to be clamped together by up to 6 mm
- The range w2 can be adjusted on the M6 threaded spindle at the clamping hook
- The types S, SV and SS prevent unwanted release of the hook clamp
- In the standard version the hook clamps 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 conditions under which these hook lock clamps are used such as vibration or shock loads, the holding capacity can be adversely affected
- The catch bracket is included
- Type A: without safety catch
- Type S: with safety catch
- Type SV: for safety catch with padlock
- Type SS: with lock
- No. 1: long type
- No. 2: short type
