Jergens 39901 Speed Handle 2 Offset Arms Aluminum

Product Description

The JERGENS 39901 is a two-arm offset speed handle with a blank hub, designed for manual positioning and clamping applications in industrial and trade environments. Machined from aluminum with a mill finish, it provides a lightweight yet durable grip for operators who need quick, tool-free adjustment of threaded fasteners, fixtures, or workholding assemblies. The handle stands 1.5 inches overall in height with a hub diameter of 1.125 inches and a hub height of 1 inch. The blank hole type means the hub bore is unfinished, allowing machinists or toolroom technicians to tap or bore it to a custom specification on-site.

This speed handle is suited for use in machine shops, assembly lines, and fixture tooling setups where rapid manual adjustment is required. The offset arm configuration improves clearance in confined spaces and provides a natural ergonomic sweep during operation. It is a standard toolroom and MRO component installed by machinists, tool and die makers, and maintenance technicians across light and medium industrial applications.

Key Features

• Two offset arms for improved clearance and ergonomic hand sweep
• Blank hub bore - field-tappable or borable to custom thread or diameter specification
• Aluminum construction with mill finish for lightweight durability
• 1.5-inch overall height suits low-profile fixture and clamping setups
• 1.125-inch hub diameter with 1-inch hub height for solid grip engagement

Compatibility

Designed as a standard-style replacement or original-fit speed handle for industrial fixtures, workholding assemblies, and manual clamping setups requiring a two-arm offset configuration with a custom-bored hub.

Installation Notes

Installation is performed by machinists or toolroom technicians. Because the hub is supplied blank, the bore must be drilled and tapped to the required thread size and depth before assembly. Ensure the mating shaft or fastener is de-energized and all motion is arrested before installing or removing the handle. Follow applicable shop safety procedures and fixture manufacturer guidelines when integrating into a workholding system.
