De-sta-co 207-UR Toggle Clamp 375 Lb U-bar Flanged Base

Product Description

The DE-STA-CO 207-UR is a manual hold-down toggle clamp with a vertical handle orientation and a U-bar style pressure bar, designed for workholding and fixturing applications on machine tables, jigs, and assembly fixtures. Rated at 375 pounds (1670 N) of holding capacity, it delivers reliable clamping force through a straight carbon steel handle with 57 degrees of handle movement and 99 degrees of bar opening for fast part loading and unloading. The flanged base mounts to flat surfaces using four mounting holes. A zinc finish coating provides corrosion resistance in light-duty shop environments. Machinists, tool and die makers, and production line technicians are the primary installers of this clamp.

The 207-UR is suited for vertical hold-down clamping in repetitive production setups where consistent, repeatable clamp force is required. It is commonly used on drill press tables, welding fixtures, woodworking jigs, and fabrication benches where a fixed-spindle U-bar provides even pressure distribution across a workpiece. The included hardware - two nuts, flanged washers, a hex head spindle, and Toggle Lock Plus - makes the unit ready for installation without additional fastener sourcing.

Key Features

• 375 lb (1670 N) holding capacity with maximum mechanical advantage of 6:1 and 12:1
• Vertical handle orientation with 57-degree handle movement for low-profile clearance
• 99-degree bar opening allows quick workpiece loading and unloading
• Fixed spindle U-bar with 5/16-18 thread and 1.3-inch spindle travel for adjustable clamping height
• Four-hole flanged base (mounting hole diameter 0.28 inches) for stable, rigid surface mounting
• Zinc-coated carbon steel construction with red straight handle for visual identification
• Includes Toggle Lock Plus mechanism for added security against accidental release

Compatibility

Designed as an OEM-style replacement or direct-fit hold-down toggle clamp for vertical fixturing applications requiring a flanged base and U-bar pressure bar configuration. Industry Number 207-UR confirms direct cross-reference to DE-STA-CO standard catalog.

Installation Notes

Installation is performed by machinists or fixture builders using standard hand tools. Power down or de-energize any associated machine before mounting or adjusting the clamp assembly. Secure the flanged base using all four mounting holes to prevent rocking under load. Adjust the hex head spindle to set clamping height before final tightening of the included locknuts, and verify the clamp passes fully over-center to the locked position before applying workpiece load.
