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 over stressed.

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

Sizes available: 100mm (4in), 150mm (6in), 200mm (8in) and 250 (10″)
