Gibraltar D4-15A-G Offset Clamping Handle 1 Arm

Product Description

The GIBRALTAR D4-15A-G is a single offset arm clamping handle designed for use in workholding, fixturing, and machine tooling applications. Built from steel, this handle features a tapped hole with a 5/16-18 thread, allowing it to thread directly onto a stud or bolt without the need for a separate nut. The offset arm configuration positions the ball grip away from the clamping surface, giving the operator better leverage and clearance in tight setups. The ball diameter measures 0.750 inches and the hub diameter is 0.625 inches, providing a compact, sturdy grip point for repeated actuation.

This clamping handle is suited for use in light industrial and precision machining environments where a reliable, hand-operated fastening solution is needed. Common applications include drill press fixtures, milling machine vises, jig plates, and fabrication positioners. The single offset arm design is well suited to installations where a straight pull or push action is preferred over a multi-arm handle. Machinists, tool and die makers, and maintenance technicians typically install these handles as part of custom or OEM fixturing assemblies.

Key Features

• Single offset arm design for improved clearance and leverage in confined fixturing setups
• Tapped 5/16-18 hole threads directly onto standard studs or bolts
• Steel construction for durability in industrial workholding applications
• 0.750 inch ball diameter provides a comfortable, positive hand grip
• Arm spread of 2 inches for adequate reach without excessive bulk
• Hub diameter of 0.625 inches and hub height of 0.4375 inches for compact mounting footprint

Compatibility

Designed as an OEM-style or replacement clamping handle for fixturing, jig, and tooling assemblies requiring a 5/16-18 tapped connection point.

Installation Notes

Installation requires threading the handle onto a compatible 5/16-18 stud or threaded fastener. Ensure the mating stud thread engagement is sufficient for the load applied before final tightening. No special tools are required for hand installation; use a wrench only on the mating fastener, not on the handle body. Confirm all clamping components are secure before operating any machine or fixture.
