Gibraltar KN5C-B4-22-G Ball Knob 1-1/2 in Female Insert

Product Description

The GIBRALTAR KN5C-B4-22-G is a thermoplastic ball knob with a female insert mount designed for use on machinery, fixtures, and industrial equipment where a secure, hand-operated grip point is needed. The knob measures 1-1/2 inches in diameter and 1-13/32 inches in height, with a 5/8-inch hole depth sized for a 5/16-18 threaded insert. The smooth grip surface and black thermoplastic construction make it a practical choice for control knobs, panel adjustments, and positioning applications across a wide range of trade and industrial settings.

This ball knob is suited for use in light manufacturing, HVAC equipment panels, electrical enclosures, and general industrial assembly where a low-profile, hand-adjustable fastener is required. The female insert design allows the knob to thread directly onto a male stud or bolt already installed in the assembly, making it a straightforward replacement or original-installation component for maintenance technicians and equipment assemblers.

Key Features

• Female insert mount accepts 5/16-18 threaded studs
• 1-1/2 inch diameter provides a comfortable hand grip for frequent adjustments
• Thermoplastic construction resists corrosion and is lightweight
• Smooth grip surface suits clean-room and general industrial environments
• Compact 1-13/32 inch height keeps the profile low on panels and fixtures

Compatibility

Designed as an OEM-style replacement or direct-install ball knob for machinery, equipment panels, and fixtures requiring a 5/16-18 female insert mount.

Installation Notes

Installation requires a properly sized 5/16-18 male stud or bolt threaded into the receiving assembly. Hand-tighten the knob onto the stud until snug — do not use power tools, as overtightening can damage the thermoplastic insert. Ensure the mating stud does not exceed the 5/8-inch hole depth to avoid bottoming out and preventing full seating.
