De-sta-co 309-UR Toggle Clamp 750 Lb Horizontal

Product Description

The DE-STA-CO 309-UR is a manual hold-down toggle clamp designed for horizontal clamping applications requiring a rated holding capacity of 750 pounds (3335 N). Built from carbon steel with a zinc finish coating, this clamp features a U-bar with a fixed spindle end and a flanged base for secure four-hole mounting. The T-handle moves through 168 degrees of travel, and the bar opens to 90 degrees, giving technicians and machinists quick, positive workpiece control. It ships with one spindle, two nuts, and two washers. This clamp is installed by machinists, fixture builders, welding professionals, and production line technicians wherever repeatable hold-down force is required.

The 309-UR is suited for use in manufacturing fixtures, welding jigs, woodworking stations, and assembly tables. Its horizontal handle orientation and flanged base make it compatible with flat mounting surfaces where vertical clearance is limited. The 3/8-16 spindle thread and 1.06-inch spindle travel allow for fine adjustment to accommodate workpiece thickness variation. Applications span light industrial and production environments where a compact, reliable manual clamp is needed to secure parts during machining, welding, or inspection operations.

Compatibility

Designed as an OEM-style hold-down toggle clamp for use in manufacturing fixtures, welding jigs, and assembly tooling requiring a horizontal, flanged-base U-bar clamp with a 750 lb hold-down rating.

Installation Notes

Installation is performed by machinists or fixture builders using standard hand tools. Power down or de-energize any associated automated equipment before mounting or repositioning the clamp. Secure all four mounting holes through the flanged base to a rigid surface to achieve the rated holding capacity. Verify spindle adjustment and clamp engagement before applying load to the workpiece.
