Bessey TW28-30-12K Manual Hold Down Clamp 1100 Lb

Product Description

The BESSEY TW28-30-12K is a manual hold down clamp built for stationary clamping applications in fabrication, woodworking, and metalworking environments. Constructed from steel, it delivers 1100 pounds of clamping pressure and a matching 1100-pound holding capacity. The clamp mounts via a 28mm stud and opens to a maximum of 12 inches, making it suitable for securing workpieces of varying thickness to fixtures, jigs, or machine tables. Licensed tradespeople and shop technicians who need reliable, repeatable hold down force will find this clamp well suited to production and bench work environments.

This clamp is designed for use in manual clamping setups where a stud-mounted, vertical hold down configuration is required. With a throat depth of 4-3/4 inches and a clamp height of 15-3/4 inches, it accommodates workpiece positioning across a range of fixture layouts. The 6-7/8-inch arm length provides the leverage geometry needed for consistent clamping pressure without power assist. Typical applications include welding fixtures, woodworking jigs, and general fabrication hold down setups.

Installation Notes

Installation is typically performed by fabricators or machine operators familiar with fixture design. Ensure the mounting surface is flat and the stud threads are clean before installation. Verify that the selected mounting point can sustain the full rated clamping load before putting the clamp into service. Confirm workpiece positioning and clamp arm travel before applying final clamping pressure.
