Hertel CH-301-B Straight Line Action Clamp 100 Lb

Product Description

The HERTEL CH-301-B is a standard straight line action clamp designed for workholding applications in machining, fabrication, and fixture setups. It delivers a 100 lb holding capacity with 0.6575 inches of plunger travel, making it suited for light-duty clamping tasks where consistent, repeatable force is required. The clamp features a flanged base for secure surface mounting, a straight red handle with 180 degrees of handle movement, and a zinc-coated steel body for corrosion resistance. A 1/4-20 external-threaded round plunger provides straightforward adjustability. The package includes one spindle and two nuts. Machinists, toolmakers, and fixture builders are the primary installers of this component.

This clamp is used in jig and fixture applications across light manufacturing, job shops, and toolroom environments. The flanged base with three mounting holes allows direct bolting to fixture plates, tombstones, or work surfaces. With an overall length of 2.815 inches and an overall height of 1.59 inches, the CH-301-B is well suited to compact fixture designs where space is limited. It is a standard off-the-shelf clamp appropriate for production and prototype fixture builds alike.

Compatibility

Designed as an OEM-style replacement or standard addition to straight line action clamp fixture assemblies requiring a flanged base, 3-hole mounting pattern, and 1/4-20 plunger thread.

Installation Notes

Installation is typically performed by machinists or toolmakers during fixture assembly or maintenance. Secure the flanged base using fasteners through all three mounting holes to prevent rocking under load. Verify that the plunger thread engagement and clamping force are appropriate for the workpiece material before production use. Always release clamp pressure and confirm the fixture is free of stored mechanical energy before adjusting or removing the clamp.
