De-sta-co 381 Pull-action Latch Clamp 1000 Lb J-hook

Product Description

The DE-STA-CO 381 is a horizontal pull-action latch clamp rated at 1,000 lb (4,448 N) load capacity, designed to secure workpieces or fixtures by pulling the clamping bar toward the base rather than pressing down. Built from carbon steel with a straight red handle, it delivers a 6.13-inch drawing movement over a 13.45-inch overall length. The flanged base and J-hook bar style make it well suited for applications that require positive latch retention with quick manual release. Installation and adjustment are handled by maintenance technicians, tooling engineers, or fixture builders working on production or assembly equipment.

This clamp is used in horizontal clamping orientations on jigs, fixtures, tooling plates, and production workholding setups in manufacturing and industrial environments. The flanged base mounts directly to flat surfaces using four fasteners through the 0.41-inch diameter mounting holes. The included patented thumb control lever provides controlled release, and the threaded J-hook allows bar position to be fine-tuned for varying workpiece thicknesses. It is a practical choice for moderate-duty clamping tasks where consistent pull force and quick-release access are both required.

Key Features

• 1,000 lb (4,448 N) rated load capacity for reliable moderate-duty clamping
• Horizontal pull-action design draws the J-hook bar toward the base for positive latch engagement
• Flanged base with 0.41-inch diameter mounting holes for secure four-point surface attachment
• Includes patented thumb control lever for controlled, repeatable release
• Threaded J-hook allows field adjustment to match workpiece geometry
• Carbon steel construction with straight red handle for durability and visibility on the shop floor

Compatibility

Designed as an OEM-style pull-action latch clamp for use on industrial jigs, fixtures, tooling plates, and workholding assemblies requiring horizontal clamping with a flanged base mount.

Installation Notes

Mount to a clean, flat surface using appropriately sized fasteners through the four flanged base holes; verify that all mounting hardware is fully torqued before putting the clamp into service. Adjust the threaded J-hook to achieve proper engagement with the mating bar or keeper before applying load. Power down or de-energize any associated machinery before installing or servicing the clamp on active tooling. Follow applicable facility safety and machine-guarding standards during installation.
