Bessey STB-18 Sliding Arm Bar Clamp 18 in 4880 Lb

Product Description

The BESSEY STB-18 is an F-style sliding arm bar clamp built for heavy-duty fastening and assembly work. It delivers 4,880 pounds of clamping pressure across an 18-inch maximum capacity with a 7-inch throat depth, making it well-suited for large panel glue-ups, cabinet assembly, and structural woodworking tasks. The bar rides on a steel rail measuring 1-37/64 inches by 25/32 inches, providing a rigid, torque-resistant platform. A forged steel T-handle gives the user precise pressure control without slipping. The electrogalvanized finish resists corrosion in shop environments. A swivel pad is included with the standard rail profile to maintain even contact on angled or irregular workpiece surfaces.

The STB-18 is designed for professional woodworking shops, millwork operations, cabinet makers, and general contractors who need a reliable, high-pressure clamp for repetitive or demanding assembly work. The F-style sliding arm design allows fast one-hand positioning before the spindle is tightened, reducing setup time on multi-clamp glue-ups. The 18-inch rail length and 7-inch throat depth accommodate medium to large workpieces, including face frames, door assemblies, and solid-wood panels.

Key Features

• 4,880 pounds of clamping pressure for heavy-duty assembly applications
• 18-inch maximum capacity with a 7-inch throat depth

Compatibility

Designed as a replacement or addition for professional clamping setups requiring an F-style bar clamp in the STB series with an 18-inch capacity and 7-inch throat depth.

Installation Notes

Position the sliding arm against the workpiece before engaging the spindle to avoid unnecessary wear on the rail. Always ensure the swivel pad is seated flat against the workpiece surface before applying full clamping pressure to prevent slipping or marring. Clamps should be checked periodically for rail deformation or spindle thread damage, especially after heavy-load cycles. No power tools are required for operation or standard maintenance.
