This 6" bar clamp combines high-quality standards with a low price and lightweight construction, making it ideal for patternmakers, wood- and metalworkers, and homecrafters. The multiple-disc clutch permits instant adjustment, secure hold, and easy release. The bar is constructed of spring steel and measures 1/4 by 3/4 inch, with a 3/8-inch-diameter steel screw and a 2-1/2-inch reach from the edge of the bar to the center screw. These are our most popular medium-duty steel bar clamps - used by homecrafters, cabinet-makers, woodworkers and metalworkers. 2-1/2" reach with a sliding-head design. The sliding head is threaded to accommodate the screw. All adjustments are made in the movable sliding head, making this style fast-acting, easy to open and close and suitable for "close quarters" clamping. Strong, light-weight steel bars are rust-resistant. Multiple-Disc-Clutch holds securely at any point along the bar.
