Angle clamps ES of die-cast aluminum have cylindrical clamping points machined by cutting methods. Two clamping points have a slitted cross-section and one has no clamping slit.
All bores of the clamping points are arranged at an angle of 90° to each other. The slitted bores lie in a plane, while the bore cross-section without clamping slit is perpendicular to this plane. All bores receive typically available construction tubes with full surface contact over the entire cross-section.
At the screw points, hex socket cap screws or adjustable clamping levers reduce the slitted bore cross-section. Grub screws with cup points act radially on the cross-section of the bore for clamping without a clamping slit. Centering bores on the clamped tube prevent pressure points and enable precise positioning.
Clamping 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 a clamping lever is lower due to the shorterclamping lever length.
