Gibraltar ABK-056-G Ball Knob 1 Inch Aluminum Threaded Hole

Product Description

The GIBRALTAR ABK-056-G is a smooth-grip ball knob with a threaded hole mount, designed for manual adjustment and control applications in mechanical and industrial assemblies. Machined from aluminum with a natural finish, the knob measures 1 inch in diameter and accepts a 3/8-16 threaded fastener with a hole depth of 0.5 inches. Weighing just 0.05 pounds, it is a lightweight, corrosion-resistant option suited for repeated hand-operation where a secure, comfortable grip is needed. HVAC technicians, electricians, and equipment fabricators commonly use this type of knob on control panels, damper handles, access doors, and adjustment mechanisms.

This ball knob is appropriate for residential and light commercial mechanical assemblies where a compact, threaded-mount control point is required. Typical install scenarios include panel board adjusters, equipment enclosures, duct damper actuators, and service access hardware. The 3/8-16 thread size is a common standard fastener size, making this knob a straightforward drop-in for many existing installations without custom hardware.

Key Features

• Threaded hole mount with 3/8-16 thread size for direct bolt-on installation

Compatibility

Designed as an OEM-style replacement or direct upgrade for mechanical assemblies requiring a 3/8-16 threaded-hole ball knob with a 1 inch diameter profile.

Installation Notes

Install by threading onto a 3/8-16 stud or bolt by hand until snug — no special tools required for most applications. Ensure the mating stud does not exceed the 0.5 inch hole depth to avoid bottoming out. If used on live electrical enclosures or control panels, de-energize the equipment before making any hardware adjustments per applicable NEC guidelines. Inspect threads on both the knob and the mating fastener before installation to avoid cross-threading the aluminum body.
