Key specifications

Selecting the right option

Select jaw width based on the workpiece depth to be spanned. Aluminium parallel clamps provide consistent clamping pressure over longer spans; ratchet clamps suit rapid one-handed operation. One-hand dual clamps are ideal where the other hand is holding the workpiece. Match jaw width (63mm, 100mm, 150mm, 300mm, 600mm, 900mm) to the material thickness and assembly size.
