Gibraltar G2631-45-G Gear Lever Arm Ball Knob 1/4-20

Product Description

The GIBRALTAR G2631-45-G is a gear lever arm with ball knob designed for use in mechanical positioning, adjustment, and clamping applications across industrial and trade environments. The lever arm features a 1/4-20 threaded stem, a steel shaft measuring 0.31 inches in diameter and 4.5 inches in length, and a phenolic ball knob with a 0.75-inch diameter. With a total handle length of 5.2 inches and a 3/8-inch thread engagement length, this lever arm delivers a secure, ergonomic grip for hand-operated equipment controls, jigs, fixtures, and machine tool setups. Installation requires no special tools and is performed by maintenance technicians and machine operators.

This gear lever arm is suited for light industrial machinery, fabrication equipment, woodworking machinery, and other applications requiring a hand-actuated lever with a threaded stem connection. The phenolic ball knob resists oils and common shop fluids, making it appropriate for environments where chemical exposure is a routine consideration. The steel shaft provides structural rigidity for repeated adjustment cycles in production or shop settings.

Installation Notes

Installation is performed by hand or with standard hand tools. Ensure the mating threaded hole is clean and free of debris before threading in the 1/4-20 stem. Do not over-torque the stem into softer materials such as aluminum or plastic threaded inserts. Verify thread engagement depth is appropriate for the application before putting the lever into regular service.
