Gibraltar 5A01B924A8Z001G Lobed Knob 4-point Black

Product Description

The GIBRALTAR 5A01B924A8Z001G is a 4-point lobed knob constructed from thermoplastic elastomer (TPE) in a black finish. Designed for tool-free manual adjustment and control, this knob provides a firm, ergonomic grip suitable for equipment panels, enclosures, jigs, and mechanical assemblies found in trade and industrial environments. The 1/4-20 threaded stem and 1.25-inch thread length make it compatible with standard fastener configurations. At 1.4 inches in head diameter, it delivers adequate grip surface for repeated manual operation. HVAC, electrical, and mechanical technicians commonly use lobed knobs for access panels, adjustment screws, and field-serviceable equipment components.

This knob is suited for light-duty manual fastening applications in residential and commercial trade environments. Typical install scenarios include equipment control panels, field-serviceable enclosures, HVAC service access covers, and instrumentation mounts where frequent hand-adjustment is required without tools. The TPE material offers resistance to oils and mild chemicals commonly encountered in mechanical service environments.

Installation Notes

Installation requires no tools — thread the knob onto a 1/4-20 stud or screw by hand until snug. Ensure the mating thread length does not exceed 1.25 inches of engagement to avoid bottoming out. Power down or de-energize any equipment before servicing panels or enclosures where this knob is used as an access fastener. Do not overtighten, as TPE hubs can deform under excessive torque.
