De-sta-co 371 Pull-action Latch Clamp 750 Lb Flanged Base

Product Description

The DE-STA-CO 371 is a horizontal pull-action latch clamp rated at 750 pounds (3336 N) of load capacity, built from carbon steel for durability in demanding fixture and workholding applications. It features a J-Hook bar style with a straight red handle and a patented thumb control lever that allows the operator to release the clamp with one hand. At 11.89 inches overall length and 2.58 inches overall height, this clamp is sized for medium-duty clamping stations where a low-profile horizontal hold-down is required. Machinists, fixture builders, and fabrication technicians are the primary installers of this hardware.

The 371 is designed for horizontal clamping in production fixtures, welding jigs, assembly stations, and material-handling setups where a secure pull-action latch is needed. The flanged base mounts directly to flat surfaces using four fasteners through 0.34-inch diameter mounting holes. The 5.38-inch drawing movement accommodates workpiece variation, making this clamp suitable for both manual and semi-automated line applications in light manufacturing and fabrication environments.

Key Features

• 750 lb (3336 N) load capacity for medium-duty clamping applications
• Horizontal pull-action design with 5.38-inch drawing movement
• Patented thumb control lever included for single-hand release
• Threaded J-Hook bar included - adjustable to suit workpiece height
• Flanged base with four mounting holes for rigid, flat-surface installation
• Carbon steel construction with red straight handle for quick visual identification

Compatibility

Designed as an OEM-style pull-action latch clamp for use in production fixtures, welding jigs, and assembly tooling requiring a horizontal flanged-base clamp at 750 lb load capacity.

Installation Notes

Install using standard machine screws through the four flanged-base mounting holes; verify the mounting surface is flat and rigid before torquing fasteners. Power down or de-energize any automated equipment before installing or adjusting clamps in a live fixture. The threaded J-Hook should be adjusted and locked to the correct height before placing the clamp in service to ensure full rated load engagement. Fixture builders should confirm that the 5.38-inch drawing movement and 11.89-inch overall length fit within the available envelope before finalizing mounting position.
