Gibraltar G10-2810-D Lobed Knob 4-point 1-1/4 in Black

Product Description

The GIBRALTAR G10-2810-D is a 4-point lobed knob designed for manual adjustment and fastening applications across industrial, mechanical, and equipment assembly settings. Molded from thermoplastic elastomer, it delivers a firm, comfortable grip without requiring tools. The knob features a 1-1/4 inch head diameter, a 7/8 inch overall height, and a 1/2 inch hub diameter. The threaded insert accepts a 5/16-18 stem with a 1/2 inch thread engagement depth. Its black finish suits general-purpose use in environments where a clean, professional appearance is expected. Licensed trades and equipment technicians install this type of hardware during panel assembly, machine setup, and field adjustments.

This lobed knob is suited for use on control panels, enclosures, jigs, fixtures, and light machinery where frequent hand-tightening is required. The 4-lobe profile provides multiple grip points for easy torque application without tools. It is a common hardware component in HVAC equipment cabinets, electrical enclosures, and mechanical assemblies where operators need quick access for service or adjustment.

Installation Notes

Installation requires no special tools — thread the knob onto a compatible 5/16-18 stud by hand until snug. Ensure the mating thread length does not exceed the 1/2 inch hole depth to avoid bottoming out before full clamping force is achieved. Always de-energize or shut down the equipment being serviced before replacing or adjusting knobs on live panels or enclosures. Follow applicable equipment manufacturer guidelines and relevant safety standards for the installation environment.
