De-sta-co 245-U Toggle Clamp 1000 Lb U-bar Flanged Base

Product Description

The DE-STA-CO 245-U is a manual hold-down toggle clamp designed for horizontal clamping applications where secure, repeatable workpiece fixturing is required. Built from carbon steel with a zinc finish coating, it delivers a holding capacity of 1,000 pounds (4,450 N) through a straight handle with 74 degrees of handle movement and a U-bar that opens to 105 degrees. The flanged base provides four-point mounting for stable, low-profile installation on fixtures, jigs, and workholding tables. Machinists, toolmakers, and fabricators use this clamp in production and assembly environments where fast-acting, positive-lock clamping is critical.

The 245-U suits horizontal hold-down clamping in manufacturing fixtures, welding positioners, woodworking jigs, and assembly stations where consistent clamping force and quick release are needed. The fixed spindle with a 1/2-13 thread allows for fine height adjustment, accommodating varying workpiece thicknesses. The U-bar style allows clamping over protruding features or around irregular workpiece geometry. The red straight handle offers clear visual confirmation of open and closed states in production environments.

Key Features

• 1,000 lb (4,450 N) holding capacity for heavy-duty workpiece fixturing
• U-bar with 105-degree opening accommodates varied workpiece profiles and protruding features
• Fixed spindle, 1/2-13 thread, 3.20 inches of spindle travel for height adjustment
• Flanged base with four mounting holes, 0.34-inch diameter, for rigid fixture mounting
• Carbon steel construction with zinc finish coating for durability and corrosion resistance
• Includes one spindle, two nuts, and two washers

Compatibility

Designed as an OEM-style replacement or direct-fit component for horizontal hold-down toggle clamp applications requiring a flanged base, U-bar, and 1,000 lb holding capacity.

Installation Notes

Installation is performed by toolmakers or fixturing technicians using standard hand tools. Secure the flanged base through all four mounting holes to ensure even load distribution and prevent clamp rotation under load. Adjust the fixed spindle to the appropriate height before locking down the jam nuts. Verify the clamp achieves full over-center lock in the closed position before placing the fixture into service.
