GSQ Joint clamps, aluminum

Product description

Joint clamps GSQ of die-cast aluminum have slitted clamping points machined by cutting methods. They are comprised of swivel clamps LST and LSQ.

The clamping point bores are situated in a plane and are connected by the clamping joint to swivel by ± 90°, from perpendicular to parallel. 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.

A hex socket cap screw or an adjustable hand lever at the clamping joint serves for locking the joint axis. The clamping joint can be adjusted either steplessly or based on the serration pattern.

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.
