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 .
