Gibraltar 5A01B913A8Z001G Lobed Knob 4-point Black

Product Description

The GIBRALTAR 5A01B913A8Z001G is a 4-point lobed knob made from thermoplastic elastomer (TPE) with a black finish. It is designed for manual adjustment and control applications where a secure, tool-free grip is needed. The knob features a 1.4-inch head diameter, a 10-32 threaded stem, and a 1-inch thread length. The TPE construction provides a firm, comfortable grip surface that resists slipping during repeated adjustments. This type of knob is commonly installed by HVAC technicians, electricians, and mechanical equipment service professionals on panels, enclosures, and equipment requiring hand-adjusted fastening.

This lobed knob suits a wide range of light-duty control and fastening applications across residential and commercial settings. Typical installations include equipment access panels, control enclosures, instrumentation housings, and serviceable mechanical assemblies. The 4-lobe profile allows finger-tightening without tools, making it well suited for components that require routine access during maintenance cycles. Its compact overall height of 0.68 inches and narrow hub diameter of 0.56 inches allow fitment in space-constrained panel layouts.

Installation Notes

Installation requires no special tools — thread the stem into a 10-32 tapped hole or onto a mating threaded stud by hand. Confirm the mating thread depth accommodates the full 1-inch thread length before installation. Power down or de-energize any enclosure or panel before servicing components in proximity to live electrical parts. Do not overtighten, as TPE knobs are not designed for torque-tool application.
