IRWIN Record Heavy-Duty 120 Series G-Clamps are the strongest Record clamps, recommended particularly for metal working and fabrication work where a very high clamping force is demanded.

They have a drop-forged steel frame for strength and durability with a swivel shoe which helps clamping on uneven surfaces. The twin-start ACME cold rolled thread for faster operation and the fused steel handle will bend before the clamp can be overstressed.

A popular general purpose clamp for heavy-duty applications, for use in wood and metal working and other trades.
