Product Description

The GIBRALTAR GLH-589-G is a Type E gear lever arm with a cylindrical knob, designed for industrial machine tool and equipment applications where a reliable hand-operated control lever is required. The arm features a stainless steel shaft measuring 0.55 inches in diameter and 3.15 inches in length, paired with a phenolic cylindrical knob that measures 1.02 inches in diameter and 2.76 inches in length. The M12x1.75 threaded stem provides 0.63 inches of thread engagement. Total handle length is 5.91 inches. The combination of a corrosion-resistant stainless steel shaft and durable phenolic knob makes this lever suitable for demanding shop environments.

This gear lever arm is used in machine tool positioning, clamping, and adjustment applications where operators need a firm, ergonomic grip on a lever control. The cylindrical knob profile suits applications requiring a full-hand or palm grip. It is a standard off-the-shelf industrial hardware component installed by machine builders, maintenance technicians, and millwrights on equipment requiring manual feed, lock, or directional control functions.
