Bessey J18-8 Sliding Arm Bar Clamp 8 in 880 Lb

Product Description

The BESSEY J18-8 is a sliding arm bar clamp built for heavy-duty fabrication, woodworking, and metalworking applications. It delivers 880 pounds of clamping pressure through a 5/8-inch high carbon steel spindle, providing reliable holding force across a maximum jaw capacity of 8 inches. The electrogalvanized steel frame resists corrosion and holds up in shop environments. The step-over clamp design and 4-3/4-inch throat depth allow clearance over workpiece edges and raised surfaces. A forged steel T-handle gives consistent torque application without slipping. This clamp is used by fabricators, millwrights, carpenters, ironworkers, and general tradespeople who need a dependable, adjustable clamp for glue-ups, assembly, and fixturing work.

The J18-8 fits into the BESSEY Series J18 line of sliding arm bar clamps. It is suited for both residential shop work and light commercial fabrication environments. The 10-inch rail length accommodates a range of workpiece thicknesses up to the full 8-inch maximum capacity. The standard swivel pad or MorPad inclusion makes the clamp adaptable to flat, angled, or irregular clamping surfaces without marring the workpiece. Light-duty steel pads provide firm contact without excessive bite into softer materials.
