The Dual Action Clamp, 300mm is a quick-action bar clamp designed to hold workpieces securely during assembly, glue-up, routing and general workshop tasks. Its primary use is one-handed clamping where a rapid initial closure is needed followed by a fine, controlled tightening for accurate clamping pressure.

Construction comprises a hardened steel bar with a durable powder-coated finish and die-cast aluminium main body for reduced weight. The clamping spindle is made from heat-treated steel with a zinc-passivated finish to resist corrosion. The spindle uses an M10 coarse metric thread manufactured to ISO 965-1 tolerances, giving reliable, serviceable adjustment. The clamp offers a pistol-grip quick-release trigger for rapid approach and a separate threaded spindle for final pressure control—no separate drive tool is required. Jaw faces are reinforced with non-marring pads to protect timber and finished surfaces.

Typical applications include woodworking and joinery glue-ups, cabinetry, light metalwork, automotive trim and maintenance tasks where temporary but reliable clamping is required. The dual-action functionality is particularly useful for repetitive assembly jobs on production benches and for single-operator tasks where speed and control are both important.

Key benefits include time-saving operation from the quick-release trigger combined with the precision of the threaded spindle, good corrosion resistance from the powder coat and zinc passivation, and strong, repeatable holding power thanks to the hardened steel bar and M10 spindle. Compatibility with common workshop materials is high due to the non-marring jaw pads and the ability to fine-tune pressure without over-tightening. The clamp’s 300mm clamping capacity makes it suitable for most domestic and light industrial tasks.
