Sleeve clamps MS of die-cast aluminum have slitted clamping points machined by cutting methods.
The clamping point bores are situated concentrically on an axis. They receive typically available construction 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.
