Strong G-type clamp made from engineering plastic: lightweight and easy to handle while providing a reliable grip for woodworking and carpentry tasks. Ideal when you need stability without heavy metal clamps. Quick-release screw positioning: the fast-moving screw positioning mechanism lets you set and lock the clamp quickly. Speeds up repeated adjustments, making clamping more efficient and reducing setup time. Expansion and contraction design for flexible clamping: accepts a range of workpiece thicknesses so you can use the same clamp on different jobs. Clamping capacity: 5.1 cm (2 in) model: 0–50 mm 7.6 cm (3 in) model: 0–80 mm Practical performance: secure hold for gluing, holding pieces during cutting, routing or sanding, and maintaining alignment in assembly work. The combination of a fast screw positioner and a flexible jaw range makes it suitable for both quick tasks and more precise operations. Compatibility and sizing: choose the 2 in (5.1 cm) model for smaller parts and tight spaces; choose the 3 in (7.6 cm) model when you need a wider opening and greater range. Both are designed for common woodworking and carpentry projects. Use scenarios: Gluing small frames or trim: hold pieces square and tight while the adhesive cures, with quick adjustments between clamping points. Routing or sanding edges: secure the workpiece to a bench or table so you can work safely and consistently without movement. Assembly and alignment: hold parts in position when marking, pre-drilling, or temporarily aligning components during build-up. What you get: A lightweight, easy-to-use G-type clamp that speeds setup, adapts to a variety of workpiece sizes, and delivers a secure hold for everyday woodworking and carpentry tasks.
