Industrial Clamping Tool
The BESSEY SQ-4 bar clamp is built for industrial assembly, woodworking, gluing and metalworking tasks. A rigid steel bar and a Bar Slide mechanism let you set the adjustable sliding head against a fixed head for uniform pressure across the workpiece. It suits tradespeople who need a single 6 in capacity clamp with a 2,660 lb force rating.
Quick Bar Slide Setup
The sliding head moves along the 55/64 in bar and locks by turning the 4 5/8 in steel handle until the 13/32 in thick rail grips the work. Common issues appear when the pad is missing or the threads are fouled with glue, so clean the mechanism before each job. The standard rail profile and pad ship in the box for immediate use.
Sustained Pressure Performance
At 2.35 lb the steel frame resists flex while the rated 2,660 lb axial force holds joints through long glue cure cycles. The fixed head and sliding jaw maintain alignment without creep when the handle stays tightened. It is not for jobs that demand a wider opening or a lighter one-hand squeeze clamp.
