GSF Joint clamps, aluminum

Product description

Joint clamps GSF of die-cast aluminum have a slitted clamping point machined with cutting methods. They are comprised of swivel clamps LSF and LST.

The clamping point bore is centered in the plane and can be rotated by ± 90° perpendicular to the flange face. It receives typically available construction tubes with full surface contact over the entire cross-section of the bore.

At the screw point, a hex socket cap screw or an adjustable hand lever reduces 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.

The flange with four bores serves as an interface or for fastening the clamp to the place of use.

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.
