BESSEY 2400S-12 High-Performance 12″ Clamp with 5-1/2″ Throat Depth

Heavy-Duty Sliding Arm Clamp with Grip Handle and MorPad for Welding & Metal Fabrication

The BESSEY 2400S-12 is a heavy-duty F-style welding clamp designed to handle high-pressure clamping needs in fabrication shops, maintenance departments, and metalworking facilities. With a 12″ clamping capacity and a deep 5-1/2″ throat, this clamp delivers up to 2,800 lbs of force, providing reliable holding power for steel assembly, jig setups, and welding preparation.

Built on a legacy of engineering that dates back to BESSEY’s original all-steel sliding-arm clamp from 1952, the 2400S-12 incorporates modern, patented features that deliver improved performance and durability. The drop-forged, tempered steel sliding arm offers direct and stable force transmission, while the patented rail profile enhances strength under pressure. The addition of the MorPad tilting pad—which adjusts up to 35°—helps maintain full-face contact with irregular surfaces and reduces internal stress on materials, boosting both service life and performance.

The clamp includes a high-strength, electro-galvanized sliding pin handle, now fitted with a comfortable BESSEY Grip Handle for better control and reduced fatigue during torque-intensive tasks. Backed by heat-treated, corrosion-resistant components and ACME-threaded spindle construction, this 12″ clamp is ideal for medium- to heavy-duty applications in tight setups where a deep reach and strong hold are required.
