Bar clamp for welding and assembly

This Bessey GS30K bar clamp provides a 12 in. maximum jaw opening and a 5 1/2 in. throat depth for general purpose clamping. Tempered cold drawn forged steel construction suits welding, assembly and maintenance work. A classiX pad with swivel face and standard pad type adapts to uneven surfaces. The steel handle measures 3 15/16 in. in length.

Suits general workshop and home tasks

This clamp fits users who need a single, sturdy bar clamp for occasional fabrication or repair jobs around the house or workplace. It is not for buyers who require multiple clamps for simultaneous glue-ups or high-volume production clamping. Deep-throat or extra-wide opening needs are not met by this model.

12 in. maximum jaw opening

The 12 in. maximum jaw opening is the key specification that determines whether this clamp fits the workpiece. The 5 1/2 in. throat depth defines how far the clamping force reaches from the bar edge. Both dimensions must match the project requirements for the tool to be suitable.

Questions about this item

Does the steel handle get hot or slip when I apply high clamping force all day?

The steel handle measures 3 15/16 in. and is forged from tempered cold drawn steel, so it resists heat build-up and provides a firm grip during extended clamping tasks.

What workpiece thickness can the 5 1/2 in. throat depth actually reach?

The 5 1/2 in. throat depth lets the clamp reach 5 1/2 in. from the bar edge, so it clears flanges or rails up to that depth while the 12 in. jaw opening spans the part.

Will the classiX swivel pads damage softer wood or aluminium I keep in the shop?

The classiX pads have a swivel face that self-aligns and measure 1 5/32 x 2 1/4 in., distributing pressure evenly to protect softer materials during clamping.
