GN821 Hook Clamp, Steel or Stainless Steel, Lockable
Hook clamps GN 821 are used among others for secure holding of flaps and container lids. The clamps will lock securely over the centre and are thus vibration proof. Robust, low profile design.
The stroke w1 of the clamping hook can pull the parts to be clamped together by up to 6mm. The range w2 can be adjusted on the M6 threaded spindle at the clamping hook.
The types S, SV and SS include a safety catch to 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 guideline 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.
