De-sta-co 331 Pull-action Latch Clamp 720 Lb Flanged Base

Product Description

The DE-STA-CO 331 is a horizontal pull-action latch clamp rated at 720 lb (3,202.72 N) of load capacity, designed to secure workpieces, fixtures, or panels with a positive latching action. The clamp features a straight red handle, a threaded U-Hook bar, and a flanged base for bolted mounting to flat surfaces. Overall length is 6.07 inches and overall height is 1.97 inches. The drawing movement measures 1.75 inches, controlling the travel distance of the U-Hook during engagement. The body is constructed from carbon steel for durability in industrial and production environments. This clamp is installed by machinists, toolmakers, fixture builders, and production technicians.

The DE-STA-CO 331 is suited for horizontal clamping applications in jigs, fixtures, tooling plates, and assembly stations where a pull-type latch is required to hold components securely in position. It is commonly used in light-to-medium industrial production settings, both in manual assembly lines and custom fixture work where repeatable hold-down force and quick release are priorities. The flanged base allows direct surface mounting without requiring additional hardware beyond standard fasteners.

Compatibility

Designed as an OEM-style replacement or direct-use horizontal pull-action latch clamp for industrial jigs, fixtures, and tooling assemblies requiring a flanged-base U-Hook clamp at 720 lb capacity.

Installation Notes

Installation is performed by fixture builders, toolmakers, or maintenance technicians. De-energize or lockout any associated powered equipment before mounting or adjusting the clamp. Secure the flanged base using appropriately sized fasteners through the 0.27-inch diameter mounting holes. Adjust the threaded U-Hook to achieve proper drawing movement and confirm the thumb control lever engages and releases cleanly before putting the clamp into service.
