De-sta-co 91090 Toggle Clamp Vertical 385 Lb U-bar

Product Description

The DE-STA-CO 91090 is a manual hold-down toggle clamp designed for vertical clamping applications in industrial fixturing, welding, and assembly operations. It delivers a holding capacity of 385 pounds (1,710 newtons) through a straight, red-handled lever that travels 60 degrees to lock the U-bar in place. The U-bar opens 100 degrees for wide workpiece clearance and provides 2.4 inches of spindle travel for precise hold-down force adjustment. Constructed from carbon steel with a zinc finish coating, the 91090 is built for repeated use in production environments. Machinists, fixture builders, and fabricators install this clamp as part of jig and workholding setups.

This clamp suits horizontal surface mounting in welding fixtures, machining jigs, assembly stations, and quality-control holding fixtures. The front flanged base configuration positions the toggle mechanism at the leading edge of the mount footprint, making it practical where side access is limited. The open bar end style accommodates various workpiece geometries without requiring a closed-end contact pad.

Key Features

• 385 lb (1,710 N) holding capacity for reliable workpiece retention
• U-bar with open bar end accommodates varied workpiece profiles
• 100-degree bar opening provides generous clearance for part loading and unloading
• 60-degree handle movement locks and releases quickly in production cycles
• 2.4-inch spindle travel allows fine adjustment of clamping height
• Carbon steel construction with zinc finish coating for corrosion resistance
• Front flanged base with 4 mounting holes for stable, secure fixture attachment

Compatibility

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

Installation Notes

Installation is performed by machinists or fixture builders using standard hand tools. Power down or de-energize any associated machinery before mounting or adjusting the clamp. Secure all four mounting holes using appropriately sized fasteners to match the 0.28-inch mounting hole diameter before applying clamping load. Verify spindle height adjustment is set and locked before cycling the handle under full workpiece load.
