Gibraltar GLH-539-G Gear Lever 3/8-16 Stem Stainless Steel

Product Description

The GIBRALTAR GLH-539-G is a Type C gear lever with a taper end, designed for use in mechanical assemblies where precise manual adjustment or locking of rotating components is required. The lever features a 3/8-16 threaded stem, a stainless steel shaft measuring 2.56 inches in length and 0.375 inches in diameter, and a phenolic knob with a 1.18-inch diameter. The taper end configuration allows secure engagement with mating shafts or hubs. Total handle length is 4.37 inches, making it suitable for applications where operator reach and torque are both considerations. This part is typically installed by machine builders, maintenance mechanics, and millwrights.

The GLH-539-G suits a range of industrial and light commercial applications including machine tool adjustments, jig and fixture locking, HVAC damper manual overrides, and general-purpose equipment controls. Its stainless steel shaft offers corrosion resistance in moderate-moisture environments. The phenolic knob provides a firm grip and withstands common shop-floor chemicals and temperatures. Thread length is 0.59 inches, which is sufficient for engagement with standard threaded bosses and inserts in equipment panels and frames.

Key Features

Compatibility

Designed as a replacement or upgrade gear lever for equipment using a 3/8-16 threaded stem interface. Verify thread engagement depth and shaft diameter clearance against the existing assembly before installation.

Installation Notes

Installation is typically performed by maintenance mechanics or machine builders familiar with threaded fastener assemblies. De-energize and lock out any associated equipment before servicing adjacent components. Standard hand tools are sufficient for installation; ensure the mating threaded boss is clean and free of debris before engaging the stem. Do not over-torque the stem into blind threaded inserts, as phenolic knob components can transmit unexpected force.
