Gibraltar ALHA-6-G Lobed Knob 4-point Aluminum

Product Description

The GIBRALTAR ALHA-6-G is a 4-point lobed knob machined from 6063-T5 aluminum, designed for manual adjustment and control applications in industrial, HVAC, and mechanical assembly environments. The knob features a 2.5-inch head diameter that provides comfortable grip and sufficient torque transfer without tools. A 3/8-16 threaded stem with 3 inches of thread length allows secure engagement across a range of panel thicknesses and shaft depths. Licensed tradespeople, equipment assemblers, and facilities maintenance technicians commonly install this type of hardware during equipment panel fabrication, control box assembly, and field servicing of adjustable components.

This lobed knob is suited for use on control panels, enclosures, machinery guards, and adjustment points where hand-tightening is required. The aluminum construction keeps weight low while providing corrosion resistance appropriate for indoor mechanical and light industrial environments. The 4-lobe profile distributes finger load evenly, reducing hand fatigue during frequent adjustments. It is appropriate for both original equipment manufacturing and replacement applications where a 3/8-16 threaded interface is present.

Key Features

• 2.5-inch head diameter for a firm, comfortable hand grip
• 4-point lobed profile distributes grip load and reduces hand fatigue
• 6063-T5 aluminum construction for lightweight, corrosion-resistant performance
• 3/8-16 threaded stem with 3 inches of thread engagement length
• Tool-free hand adjustment suitable for frequently serviced control points

Compatibility

Designed as an OEM-style replacement or direct-install lobed knob for any application using a 3/8-16 threaded interface requiring hand-adjustable control hardware.

Installation Notes

Installation is performed by hand without specialty tools in most applications. Confirm thread engagement depth against panel or shaft specifications before final assembly. Ensure the mating threads are clean and free of debris before threading the knob onto the stem. Power down or de-energize any associated equipment before servicing panels or enclosures where this knob is installed.
