Bessey Tools Rapid-Action Lever L Clamp 12 in LC12 hand tool

Rapid-action lever clamp for welding and fabrication

The Bessey LC12 lever clamp is built for welders and fabricators who need fast, secure work-holding. Its rapid-action lever reduces set-up time compared with traditional screw clamps. A 12 in jaw opening handles large assemblies, while the 5 1/2 in throat depth reaches past flanges and edges. The pivoting pad adjusts automatically to uneven or angled surfaces.

Steel construction with ergonomic handle

Forged from HAWA steel, the clamp resists distortion under heavy clamping force. The nominal rail section measures 1 7/64 x 7/16 in, providing rigidity across the full 12 in span. A steel handle transmits leverage efficiently and withstands repeated impact. The clamp face of 1 1/4 x 2 1/2 in distributes pressure evenly, and the pivoting pad maintains full contact on tapered or stepped parts.

Consistent pressure with minimal operator effort

The lever mechanism multiplies hand force, so high clamping pressure is reached without prolonged tightening. Once locked, the clamp holds position without creep, even under welding heat and vibration. At 5 lb, the tool is light enough for overhead or repetitive use yet heavy enough to stay stable on the workpiece. No external power or hydraulics are required.
