Gibraltar GLH-577-G Gear Lever Arm M6x1 Stainless

Product Description

The GIBRALTAR GLH-577-G is a Type E gear lever arm with a cylindrical knob, designed for use in mechanical positioning, clamping, and adjustment applications on industrial machinery and equipment. The arm features a stainless steel shaft measuring 0.32 inches in diameter and 2.56 inches in length, paired with a phenolic knob measuring 0.71 inches in diameter and 1.77 inches in length. The M6x1 threaded stem provides a secure, standardized mount with a thread engagement length of 0.35 inches. The overall handle length is 4.33 inches, giving operators sufficient leverage for manual adjustments. Mechanical technicians and maintenance professionals install this lever arm where precise, repeatable hand-actuated control is required.

This gear lever arm is suited for use on machine tools, jigs, fixtures, and industrial equipment requiring a compact, hand-operated control lever. It is well-suited for applications where corrosion resistance is a priority, given its stainless steel shaft construction. The phenolic knob material offers durability and resistance to oils and common shop chemicals. This part is typically installed in light to medium-duty manual control positions on fabrication, assembly, or processing equipment.

Installation Notes

Installation is typically performed by mechanical or maintenance technicians. Ensure the mating threaded bore is clean and free of debris before threading in the M6x1 stem. Power down or de-energize any equipment before servicing lever arm components mounted on moving or actuated assemblies. Do not exceed the torque capacity of the phenolic knob or the threaded stem during installation.
