Gibraltar GLH-549-G Gear Lever Knob M8x1.25 Type C

Product Description

The GIBRALTAR GLH-549-G is a Type C gear lever knob designed for industrial and mechanical control applications requiring a reliable, ergonomic hand-operated lever. The knob features an M8x1.25 threaded stem that threads onto a stainless steel shaft measuring 0.39 inches in diameter and 1.97 inches in shaft length. The phenolic knob measures 0.98 inches in diameter and 1.5 inches in knob length, with a taper end configuration that provides positive grip and secure positioning. The 0.51-inch thread engagement length and 3.46-inch overall handle length suit a range of light-duty mechanical assemblies. Installation is straightforward for maintenance techs and machine builders working on control panels, jigs, or adjustment mechanisms.

This gear lever knob is suited for use in industrial equipment, machine tool controls, and mechanical assemblies where hand-operated adjustment or locking is required. The stainless steel shaft resists corrosion in light-wash or humid environments, while the phenolic knob body offers chemical resistance and dimensional stability under repeated handling. Typical applications include manual positioning controls, fixture clamping knobs, and equipment access panels in light manufacturing or maintenance settings.

Compatibility

Designed as a standard metric gear lever knob for industrial machinery, control panels, and mechanical assemblies using M8x1.25 threaded mounting points.

Installation Notes

Installation is performed by maintenance technicians or machine builders using standard hand tools. De-energize or lock out any equipment before servicing control knobs or levers per applicable OSHA lockout/tagout procedures. Thread the M8x1.25 stem onto the mating shaft by hand until snug, then verify that the taper end seats correctly before returning the assembly to service. Do not over-torque the threaded stem, as phenolic knob bodies can crack under excessive force.
