BESSEY 2400S-20 High-Performance 20″ Clamp with 5-1/2″ Throat Depth

Heavy-Duty F-Style Clamp with Grip Handle and Tilting MorPad – Built for Welding & Fabrication

The BESSEY 2400S-20 is a durable and efficient 20-inch F-style welding clamp designed for demanding fabrication and metalworking applications. With a deep 5-1/2″ throat and a massive 2,800 lbs of clamping force, it offers extended reach and serious holding power for clamping steel components, large assemblies, and structural materials. This clamp belongs to BESSEY’s trusted 2400S series and features updated innovations built on a legacy dating back to BESSEY’s first all-steel sliding-arm clamp introduced in 1952.

With a drop-forged sliding arm, heat-treated rail, and patented MorPad contact surface, this clamp applies pressure smoothly and securely—even on uneven or angled work surfaces. The MorPad tilts up to 35°, ensuring full pad contact while reducing wear and internal friction during heavy clamping. Its ACME-threaded spindle is optimized for fast adjustment with minimal torque effort, while the high-strength handle with included grip sleeve gives operators more control and comfort under load.

The 20-inch capacity provides ample reach for clamping larger fabrications, frames, and sub-assemblies. Whether you’re working at a welding table, aligning steel rails, or securing material for layout and tack welds, this clamp delivers dependable results without slowing down your process.
