The 6″ Medium-Duty Steel Bar Clamp from Jorgensen is designed with home crafters, woodworkers, cabinet-makers, and metalworkers in mind. The Steel Bar Clamp features a 2.5″ reach and has a threaded sliding-head design to accommodate the screw and allow for easy opening and closing. The steel bars are plated, round-edged, and rust-resistant. The screw is made from cold cut steel and features ACME style threads and a varnished hardwood handle. The clamp’s casting is made from iron and is finished in an orange power coat. The multiple clutch disc is comprised of two clutch discs and a clutch spring to securely hold at any point along the bar.
