Information
GN 853 Latch Clamps feature a locking mechanism which prevents the inadvertent or vibration-induced opening of the clamp.
Another benefit of this clamp is the ability to operate it with one hand.
The tie-rod can be adjusted within the range of dimension w2.
The design of Type 1 (thread bore d1 = M8) allows the easy and individual configuration of the locking mechanism.
