De-sta-co 527 Toggle Clamp 1000 Lb Vertical

Product Description

The DE-STA-CO 527 is a manual hold-down toggle clamp rated at 1,000 lb (4,450 N) holding capacity, designed to secure workpieces firmly against a fixture surface during machining, welding, assembly, or other production operations. The clamp features a vertical handle orientation with a straight red handle, a solid closed-end bar, and a flanged two-hole base for rigid mounting. The handle travels 65 degrees to engage, and the bar opens 195 degrees for loading and unloading. Carbon steel construction with a zinc finish coating provides durability in demanding shop environments. Mechanical advantage reaches up to 23:1, maximizing clamping force from minimal operator effort.

The DE-STA-CO 527 is suited for use in manufacturing, fabrication, and assembly jig and fixture applications where repeatable hold-down force is required. The flanged base mounts directly to flat fixture plates or tooling surfaces using two fasteners through 0.41-inch diameter mounting holes spaced 1.25 inches apart. This clamp is appropriate for light-to-medium production fixtures in both job shop and high-volume manufacturing settings. Installation requires no special tooling beyond standard fasteners and a wrench.

Key Features

• 1,000 lb (4,450 N) holding capacity for firm workpiece retention
• Vertical handle orientation with 65-degree handle movement for ergonomic operation
• 195-degree bar opening allows easy part loading and clearance
• Solid closed-end bar, 0.75 inches wide and 0.748 inches thick
• Flanged two-hole base with 0.41-inch mounting holes spaced 1.25 inches apart
• Carbon steel body and handle with zinc finish coating for corrosion resistance
• Maximum mechanical advantage of 23:1 reduces required clamping force

Compatibility

Designed as an OEM-style hold-down toggle clamp for use in standard jig and fixture applications requiring a vertical, flanged-base, solid-bar configuration.

Installation Notes

Mounting is performed by machinists, toolmakers, or fixture builders using standard socket-head or hex fasteners through the two flanged-base holes. Ensure the fixture plate material and fastener grade are rated to handle the full 1,000 lb clamping load before tightening. Verify the clamp is fully locked over-center before applying any load to the workpiece. Inspect pivot pins and bar action periodically for wear in high-cycle applications.
