Cross clamps KE of matt blasted precision-cast stainless steel have a slitted clamping point 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 construction tubes with full surface contact over the entire cross-section of the bore.
At the screw points, carriage bolts together with cap nuts or adjustable hand levers reduce the bore cross-section for clamping. Type B is equipped with seals at the screw points.
Adjustable hand levers are intended for repeated, tool-free clamping. Under the designation HEK, 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.
