Gibraltar G3947-37-G Gear Lever Arm Oval Knob 3/8-16

Product Description

The GIBRALTAR G3947-37-G is a gear lever arm with an oval knob designed for manual control applications in industrial and mechanical equipment. The arm features a steel shaft measuring 0.47 inches in diameter and 3.7 inches in shaft length, paired with a phenolic oval knob that measures 1.625 inches in diameter. The 3/8-16 threaded stem provides a secure, standardized connection to equipment housings and control assemblies. With a total handle length of 6.2 inches and a 0.5 inch thread engagement length, this lever arm delivers reliable hand-operated actuation for gear selectors, valve controls, and positioning mechanisms. Installation is straightforward for maintenance technicians and mechanical assemblers working with standard threaded hardware.

This gear lever arm is suited for use in industrial machinery, HVAC equipment controls, and mechanical systems requiring a hand-operated lever with a firm, comfortable grip. The phenolic knob material resists heat and common shop chemicals, making it appropriate for service environments with elevated temperatures or fluid exposure. The 3/8-16 stem is a widely used thread specification that fits a broad range of equipment control panels and actuator assemblies. It is typically installed by maintenance technicians, mechanical assemblers, or equipment repair professionals.

Installation Notes

Installation should be performed by a qualified maintenance technician or mechanical assembler familiar with threaded hardware. Ensure the receiving equipment is de-energized and depressurized before removing or installing any control lever components. Use appropriate hand tools to thread the 3/8-16 stem to the specified engagement depth without overtightening, which can crack the phenolic knob base. Follow the equipment manufacturer's service documentation for torque and assembly requirements.
