De-sta-co 247-U Toggle Clamp Vertical 1000 Lb U-bar

Product Description

The DE-STA-CO 247-U is a manual hold-down toggle clamp with a vertical handle orientation and a flanged base, designed for workholding applications in manufacturing, assembly, and fabrication environments. It delivers a holding capacity of 1,000 pounds (4,450 N) and features a U-bar with a fixed spindle end, giving operators a secure, repeatable clamping point. The handle travels 67 degrees to lock and the bar opens 120 degrees for clear workpiece access. Built from carbon steel with a zinc finish, this clamp is suited for high-cycle industrial use. A licensed machine operator or tooling technician is the typical installer.

The 247-U is used in jigs, fixtures, and workholding stations where consistent vertical clamping force is required. It is common in metal fabrication shops, automotive assembly lines, and woodworking fixtures. The flanged base mounts via four holes and includes two flanged washers, two nuts, and an M12x1.75 spindle, making it ready to install without additional hardware. The spindle provides 3.15 inches of travel to accommodate workpieces of varying thickness.

Compatibility

Designed as an OEM-style hold-down toggle clamp for use in custom jigs, fixtures, and workholding assemblies requiring a vertical-handle, flanged-base configuration with a U-bar and 1,000 lb holding capacity.

Installation Notes

Installation is typically performed by a tooling technician or machinist. Secure the flanged base to a flat, rigid fixture plate using all four mounting holes to ensure full clamping force is transferred without base flex. Verify that the spindle thread engagement and bar clearance are appropriate for the workpiece height before cycling under load. Follow applicable workplace safety and machine guarding standards when integrating toggle clamps into automated or semi-automated fixtures.
