Gibraltar G3339-22-G Gear Lever Arm Oval Knob 5/16-18

Product Description

The GIBRALTAR G3339-22-G is a gear lever arm with an oval knob, designed for use in mechanical control and adjustment applications across industrial and trade settings. The assembly features a steel shaft measuring 0.39 inches in diameter and 2.2 inches in length, paired with a phenolic oval knob at 1 inch in diameter. The 5/16-18 threaded stem provides a secure, standardized connection point. The handle extends 3.8 inches for reliable grip and leverage during manual adjustments. This lever arm is installed by maintenance technicians and mechanical tradespeople working on equipment that requires hand-operated gear or valve control.

The G3339-22-G is suited for use in equipment panels, gear mechanisms, and control assemblies where a durable, hand-operable lever is required. The phenolic knob resists heat and common shop fluids, making it appropriate for light industrial environments. The steel shaft provides the rigidity needed for repetitive manual actuation. Typical applications include HVAC damper controls, machinery adjustment handles, and similar mechanical assemblies requiring a compact lever arm with a threaded stem connection.

Installation Notes

Installation is typically performed by maintenance technicians or mechanical tradespeople. De-energize and lock out any powered equipment before installing or replacing this lever arm. Thread the stem into the mating receiver to the appropriate engagement depth using hand tools; avoid over-tightening the phenolic knob against hard surfaces. Verify the handle moves freely through its full range of travel before returning equipment to service.
