De-sta-co 331-R Pull-action Latch Clamp 720 Lb

Product Description

The DE-STA-CO 331-R is a horizontal pull-action latch clamp rated at 720 lb (3,202.72 N) of load capacity. It features a U-hook bar style and a flanged base, making it suitable for securing workpieces or panels in fixture, jig, and production line applications. The clamp draws 1.75 inches of movement to engage the latch, and the overall length is 6.07 inches. The carbon steel body provides solid durability in industrial environments. This unit ships with a latch plate, patented thumb control lever, threaded U-hook, and Toggle Lock Plus mechanism included. Installation is handled by maintenance technicians and fixture builders working in manufacturing or fabrication settings.

The 331-R is designed for horizontal clamping applications where a pull-action engagement is required. It suits production fixtures, jigs, tooling plates, and enclosure latching where repeatable, secure hold-down force is needed. The flanged base allows direct surface mounting with standard fasteners through the provided mounting hole pattern. The straight red handle offers clear visual identification of clamp position on the line.

Installation Notes

Installation is typically performed by fixture builders or maintenance technicians using standard hand tools. De-energize or lock out any associated machinery before mounting or adjusting the clamp per applicable LOTO procedures. Secure the flanged base through all mounting holes to ensure even load distribution and prevent clamp movement under load. Verify that the latch plate alignment allows full draw travel before placing the assembly into service.
