G Clamp 12in 300mm Cast Iron Heavy Duty Woodworking

A heavy duty 12in (300mm) G clamp built for holding larger workpieces securely while you cut, glue, weld or assemble. The cast iron frame gives it the strength needed for regular workshop, garage and DIY use where a firm, steady hold matters.

Used for woodworking, metalworking and general repair jobs, this clamp is handy when boards, sections or parts need to stay in place during glue-ups, fitting and alignment. It suits bench work, home maintenance, welding preparation and assembly tasks where an extra pair of hands makes the job easier. For DIY repairs or trade use alike, it helps keep materials stable while you work more accurately.

The 300mm capacity makes it suitable for larger sections than a smaller bench clamp, giving you more reach across timber, metal or assembled components. A threaded screw allows gradual adjustment so pressure can be applied with more control, while the swivel pad helps spread contact at the clamping point. The cast iron body is made for repeated use, and the straightforward handle arrangement keeps tightening and loosening simple when moving between jobs. For regular clamping, holding and positioning work, it is a practical tool to keep close by on the bench.
