Cross clamps KK of die-cast aluminum have slitted clamping points machined by cutting methods.
The bores of the clamping points are offset in the plane and arranged at an angle of 90°. They receive typically available rods and tubes with full surface contact over the entire cross-section of the bore.
At the screw points, hex socket cap screws or adjustable hand levers reduce the bore cross-section for clamping.
Adjustable hand levers are intended for repeated, tool-free clamping. Under the designation HSK, these are available separately for individual use and in other designs.
Compared with the tool-operated hex socket cap screw, the clamping force achievable with an adjustable hand lever is lower due to the shorter lever length.
