De-sta-co 609-B Straight Line Action Clamp 299 Lb

Product Description

The DE-STA-CO 609-B is a standard straight line action clamp designed to deliver controlled, linear clamping force in fixture, jig, and workholding applications. It produces a rated load capacity of 299 lb (1330 N) with a mechanical advantage of 36:1 in the pushing direction, making it well suited for repetitive production clamping where consistent hold-down force matters. The plunger travels 1.25 inches and measures 0.44 inches in diameter with an internal thread size of 5/16-18 for adjustable tip accessories. The clamp body is carbon steel with a straight base and straight handle and weighs 0.88 pounds.

This clamp is used in industrial manufacturing, assembly, and fabrication setups where a compact, straight-line clamping action is required. The straight base configuration suits flat mounting surfaces on fixtures, welding tables, and machining jigs. It is installed by machinists, tool-and-die technicians, and assembly fixture builders who need a dependable toggle-action hold-down in tight linear arrangements. The straight handle and red grip provide quick manual actuation without tooling.

Installation Notes

Installation is performed by fixture builders or tooling technicians using standard hand tools.

Ensure the mounting surface and fasteners are rated for the full 299 lb clamping force. Inspect the plunger thread and tip adjustment for proper engagement before placing the clamp into production service.
