De-sta-co 225-U Toggle Clamp 500 Lb U-bar Flanged Base

Product Description

The DE-STA-CO 225-U is a manual hold-down toggle clamp designed for horizontal clamping applications in production, fabrication, and assembly operations. Built from carbon steel with a zinc finish, it delivers a 500 lb (2220 N) holding capacity through a straight, red-handled lever that travels 70 degrees to lock a U-bar with a 92-degree opening arc. The fixed spindle design provides a secure, repeatable clamp point with an M8x1.25 spindle thread and 1.38 inches of spindle travel. Machinists, welding fixture builders, jig makers, and production line technicians commonly install this clamp where consistent workpiece hold-down force is required in tight footprints.

The 225-U is suited for light-to-medium duty workholding on welding tables, drill press fixtures, assembly jigs, and woodworking stations. The flanged base with four mounting holes accepts standard fasteners through 0.26-inch diameter holes spaced 1 inch center-to-center lengthwise and 0.87 inches center-to-center widthwise. The overall footprint measures 6.91 inches long and 1.84 inches tall, making it a compact option for fixtures with limited vertical clearance. Hardware included with each unit: one spindle, two nuts, and two washers.

Key Features

• 500 lb holding capacity with maximum mechanical advantage of 5:1 and 12:1
• Horizontal U-bar configuration with 92-degree bar opening for easy workpiece loading
• Fixed spindle with M8x1.25 thread and 1.38 inches of travel for clamping depth adjustment
• Flanged base with four mounting holes for rigid, multi-point fixture attachment
• Carbon steel construction with zinc finish coating for corrosion resistance in shop environments
• Includes spindle, two nuts, and two washers - ready to mount out of the box

Compatibility

Designed as an OEM-style replacement or direct-fit addition for horizontal hold-down toggle clamp applications requiring a flanged base and U-bar style clamping arm.

Installation Notes

Installation is typically performed by machinists or fixture builders using standard hand tools. Mount the flanged base to a flat, rigid surface using four fasteners through the 0.26-inch mounting holes before applying any clamping load. Verify the spindle height adjustment locks the workpiece securely in the over-center position before operating the fixture under production conditions. Do not exceed the rated 500 lb holding capacity.
