The IRWIN Record Heavy-Duty 120 Series G-Clamp with 300mm capacity is the largest in this professional range, designed for the most demanding fabrication and metalworking applications. This substantial size provides maximum reach and very high clamping force, making it essential for large assemblies, thick materials, and heavy-duty industrial projects where smaller clamps simply cannot reach. Built with a drop-forged steel frame, this 300mm clamp offers exceptional strength and durability for the most intensive workshop environments. The swivel shoe ensures secure clamping even on uneven surfaces, whilst the twin-start ACME cold rolled thread enables faster operation and positioning. The fused steel handle is engineered to bend before the clamp can be overstressed, providing a crucial safety mechanism during heavy-duty use.
