Hertel CH-451 Pull-action Latch Clamp 375 Lb U-hook

Product Description

The HERTEL CH-451 is a horizontal pull-action latch clamp designed to secure workpieces, fixtures, and panels in industrial and fabrication applications. It delivers a 375 lb (1668 N) load capacity through a U-hook bar with a straight, red-painted handle that travels 180 degrees to engage or release. The flanged base mounts with four fasteners and provides a stable, low-profile footprint measuring 1.5 inches in base length and 1.94 inches in base width. Overall length is 5.63 inches and overall height is 1.44 inches. The body is steel with a zinc finish coating for corrosion resistance. Drawing movement is 4 inches, giving the operator a consistent, repeatable clamping stroke on each cycle.

The CH-451 is suited for horizontal clamping tasks in manufacturing jigs, welding fixtures, assembly tables, and machine guarding setups. Its flanged base allows direct surface mounting to steel or fabricated frames. The 4-inch drawing movement accommodates moderate part variation in workholding setups. This clamp is typically installed and serviced by tool and die technicians, machine builders, fixture designers, and maintenance mechanics in light-to-medium industrial environments.

Key Features

• 375 lb (1668 N) load and holding capacity for reliable workpiece retention
• 4-inch drawing movement provides a consistent clamping stroke
• U-hook bar style accommodates standard clamping rods and pins
• Flanged base with four mounting holes for rigid, low-profile surface attachment
• Straight red handle with 180-degree travel for clear open-closed indication
• Steel body with zinc finish coating for durability in shop environments

Compatibility

Designed as an OEM-style replacement or direct fitment horizontal pull-action latch clamp for industrial workholding fixtures, jigs, and assembly tooling requiring a flanged-base U-hook clamp with 375 lb capacity.

Installation Notes

Installation is performed by fixture builders or maintenance mechanics using standard hand tools. Mount the flanged base to a rigid surface using four fasteners through the 0.22-inch diameter mounting holes before applying any clamping load. Verify that the U-hook and clamping rod are correctly aligned prior to closing the handle to avoid side-loading the latch mechanism. Inspect the zinc-coated steel body periodically for corrosion or mechanical wear in high-cycle applications.
