De-sta-co 528 Toggle Clamp 1000 Lb Vertical

Product Description

The DE-STA-CO 528 is a manual hold-down toggle clamp designed for vertical clamping applications requiring a rated holding capacity of 1,000 pounds (4,450 N). The clamp features a solid bar with a closed end, a flanged base, and a straight red handle that travels through 177 degrees of movement. The bar opens to 180 degrees, giving installers clear access to the workpiece during loading and unloading. Built from carbon steel with a zinc finish, the 528 is suited for production fixtures, welding tables, jigs, and other industrial workholding setups where repeatable, secure clamping is required. Mechanical technicians and tooling specialists are the primary installers.

The DE-STA-CO 528 is used in light to medium industrial production environments where parts must be held firmly in place during machining, welding, assembly, or inspection. The flanged base allows direct bolt-down mounting to fixture plates or machine tables using two mounting holes spaced 1.25 inches apart. The overall footprint and 2.06-inch height under the bar make it compatible with low-profile workholding scenarios. This clamp is a common choice for fixturing applications that demand a compact vertical hold-down with high mechanical advantage.

Key Features

• 1,000 lb (4,450 N) rated holding capacity for secure workholding
• 177-degree handle movement and 180-degree bar opening for full workpiece access
• Flanged base with two mounting holes for rigid bolt-down installation
• Carbon steel construction with zinc finish coating for corrosion resistance
• Solid bar with closed end, 0.87-inch width and 0.748-inch thickness
• Maximum mechanical advantage up to 23:1 for high clamping force with low handle effort

Compatibility

Designed as an OEM-style vertical hold-down toggle clamp for use in industrial fixturing, welding jigs, assembly fixtures, and workholding applications requiring a flanged base mount.

Installation Notes

Installation is performed by tooling technicians or maintenance mechanics. Power down or de-energize any associated machinery before mounting or adjusting the clamp. Secure the flanged base to a flat, rigid surface using two fasteners through the 0.41-inch diameter mounting holes. Verify that the clamping bar clears the workpiece at full open position before cycling the handle through its range of motion.
