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
