Gibraltar 5A03A205A8Z002G Lobed Knob 4-point Tpe Black

Product Description

The GIBRALTAR 5A03A205A8Z002G is a 4-point lobed knob molded from thermoplastic elastomer (TPE) and finished in black. It is designed for manual adjustment and control applications where a secure, tool-free grip is needed. The knob accepts a 1/4-20 threaded stem with a thread engagement depth of 0.68 inches. With a head diameter of 1.99 inches and an overall height of 0.86 inches, this knob suits panel-mount and equipment-adjustment installations. Electricians, equipment assemblers, and mechanical technicians typically install this type of knob on control panels, machinery guards, and enclosures.

This lobed knob is suited for light industrial, commercial, and OEM equipment applications where operators need to make quick, hand-tightened adjustments without tools. The TPE construction provides a firm, slip-resistant grip surface that remains comfortable in typical shop and panel environments. It is commonly used on control panels, jigs, fixtures, and enclosures that require frequent access or periodic adjustment.
