Swivel clamps LMQ of die-cast aluminum have a split clamping point with round or square cross-section that has been partially machined by cutting methods. The fastening lug has a smooth surface.
The fastening lug is centered and perpendicular to the axis of the bore, which receives typically available construction tubes via multiple ribs in the cross-section.
The screw point of the fastening lug receives a hex head or hex socket cap screw or a lock nut for fastening any additional parts. At the clamping point, hex socket cap screws or adjustable hand levers reduce the bore cross-section for clamping.
By combining swivel clamps that have identical fastening lugs, it is possible to assemble any type of joint clamp.
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.
