Steel bar clamp with 8 in capacity

This Bessey Tools GS20K bar clamp is built from a steel profiled rail with a fixed head and an adjustable sliding head. Tempered drop-forged steel forms the sliding T-handle for strong torque application. Swivel jaw pads adapt to irregular workpiece surfaces. The clamp suits woodworking, metalworking, gluing, welding and general assembly tasks.

For heavy clamping up to 880 lb

Woodworkers, metalworkers and fabricators who need up to 8 in of reach and high axial force will find this clamp appropriate. It is not suited for jobs requiring longer reach beyond 8 in or for users who prefer a lightweight clamp for repetitive light-duty work. The 1.85 kg steel construction adds mass that some operators may find tiring over extended sessions.

880 lb maximum axial clamping force

The single figure that decides fit is the 880 lb maximum axial clamping force combined with the 8 in clamping capacity. If your joint demands more force or a wider opening, this clamp will not meet the requirement. For applications within those limits the steel rail and swivel jaws deliver a secure, adaptable hold.

Questions about this item

What rail thickness does the GS20K bar clamp need to fit into a jig or fixture?

The profiled rail is 13/16 in thick, so any mounting slot or fixture must clear at least that dimension.

How do you install the sliding head on the GS20K, and what step is often missed?

Slide the adjustable head onto the profiled rail from the open end, then tighten the tempered drop-forged steel handle; the step often missed is confirming the swivel jaw pad rotates freely before applying the full 880 lb clamping force.

Which part of the GS20K will need replacement after heavy daily use?

The swivel jaw pads wear first; keep spares on hand so the clamp maintains even contact across the full 8 in capacity.
