De-sta-co 207-51 Toggle Clamp Vertical 500 Lb Flanged Base

Product Description

The DE-STA-CO 207-51 is a manual hold-down toggle clamp with a vertical handle orientation and a flanged base designed for secure workpiece clamping in fixture and jig applications. It delivers a holding capacity of 500 pounds (2,220 N) through a solid closed-end bar with a 99-degree bar opening and a 57-degree handle movement arc. The carbon steel body and handle are zinc-coated for corrosion resistance. A spindle thread size of 5/16-18 and an included bolt retainer allow precise clamping height adjustment. Licensed machinists, tool and die technicians, and fabrication professionals are the primary installers of this clamp type.

The 207-51 is suited for light-to-medium production fixturing, welding positioners, woodworking jigs, and assembly line workholding where a repeatable vertical hold-down force is required. The flanged base provides a stable four-hole mounting footprint, making it appropriate for both benchtop fixtures and dedicated jig plates. The straight red handle offers clear visual status indication in busy shop environments, and the compact overall envelope fits tight fixture layouts.

Key Features

• 500 lb (2,220 N) holding capacity for reliable workpiece retention
• Vertical handle orientation with 57-degree handle movement for ergonomic actuation in confined fixture setups
• 99-degree bar opening angle provides generous clearance for part loading and unloading
• Flanged base with four mounting holes and 0.28-inch diameter hardware - mounts directly to fixture plates or benchtops
• 5/16-18 spindle thread with included bolt retainer allows fine clamping height adjustment without losing the spindle
• Zinc-finish carbon steel construction resists shop-environment corrosion

Compatibility

Designed as an OEM-style hold-down toggle clamp for use in standard fixturing, jig, and workholding applications requiring a vertical-action, flanged-base clamp with a 500 lb holding capacity.

Installation Notes

Installation is typically performed by machinists or fixture builders using standard drill-and-tap or through-bolt methods to secure the flanged base to the fixture plate. Verify that the mounting surface is flat and that all four mounting holes are used to prevent rocking under load. Disengage the clamp and relieve any workpiece pressure before adjusting spindle height. Follow applicable workplace safety standards for mechanical fixturing when operating in production environments.
