Steel.

Case-hardened, black oxidised and ground.

The clamping height can be raised using riser bars 04378 and reduced using self-aligning pads 02000 with 04620-12 to 04620-14 and 04620-22 to 04620-24
The clamps have the following advantages:
- rapid manual clamping via threaded spindle and spiral cam.
- quick and easy workpiece change by swivelling away the clamp
- compact design, therefore little space required for clamping.
- simple adaptation to even large clamping heights using the riser bars.

The clamps can be affixed in two ways:
1) in a T-slot.
2) with the M12 grub screw directly onto a plate of an e,g, fixture.
