De-sta-co 331-RSS Pull-action Latch Clamp 720 Lb Stainless

Product Description

The DE-STA-CO 331-RSS is a horizontal pull-action latch clamp rated at 720 lb (3202.72 N) of load capacity. Built from stainless steel, it is designed for clamping applications that demand corrosion resistance and repeatable holding force. The clamp features a straight handle with a red handle color, a threaded U-hook bar, and a flanged base for secure surface mounting. With an overall length of 6.07 inches and a drawing movement of 1.75 inches, it fits into tight fixture layouts without sacrificing clamping travel. Installation is typically performed by tooling technicians, fixture builders, or maintenance professionals in industrial and manufacturing environments.

The 331-RSS suits horizontal clamping setups on jigs, fixtures, molds, and workholding assemblies where a pull-action mechanism is preferred over a swing-action design. The flanged base mounts flat to a work surface or fixture plate. The included patented Thumb Control Lever and Toggle Lock Plus mechanism provide a positive lock-out indication, reducing the chance of unintended release during production cycles. This clamp is well suited for medium-duty applications in fabrication, assembly, and quality inspection fixtures.

Key Features

Compatibility

Designed as a direct-fit horizontal pull-action latch clamp for industrial jigs, fixtures, and workholding assemblies requiring a flanged-base U-hook clamp at the 720 lb load rating.

Installation Notes

Mount using fasteners that match the 0.27 inch mounting hole diameter through the flanged base; confirm the mounting surface can support the rated load before tightening. Ensure the U-hook is fully threaded and locked to the latch plate before applying clamping force. Verify Toggle Lock Plus engagement before leaving the clamp unattended in a loaded condition. Disengage all clamping force and secure the workpiece independently before performing any adjustments or maintenance on the clamp assembly.
