Gibraltar G10-2837-V Lobed Knob 4-point 2-1/4 in Black

Product Description

The GIBRALTAR G10-2837-V is a 4-point lobed knob designed for hand-tightening and manual adjustment applications in industrial, mechanical, and trade settings. Molded from thermoplastic elastomer (TPE), the knob delivers a firm, tactile grip surface that resists slipping during operation. The 2.25-inch head diameter and four evenly spaced lobes allow reliable torque application without tools. A 5/16-18 threaded stem with 1 inch of thread length provides secure engagement with standard fastener interfaces. Licensed HVAC technicians, electricians, plumbers, and equipment installers use this type of hardware on panels, access doors, guards, and adjustable fixtures throughout commercial and residential work environments.

This lobed knob is suited for use wherever a hand-adjustable fastening point is required on equipment panels, enclosures, jigs, or assemblies. Its thermoplastic elastomer construction performs reliably across typical indoor and light-duty industrial environments. The 5/16-18 thread size is a common standard found on a wide range of equipment frames and fabricated assemblies, making this knob a practical replacement or upgrade for worn or missing hardware on existing installations.

Installation Notes

Installation requires no special tools — hand-thread the knob onto a 5/16-18 threaded stud or insert until seated. Ensure the mating thread is clean and undamaged before installation to prevent cross-threading. De-energize or shut down any equipment before adjusting or replacing panel hardware. Follow applicable NEC or equipment manufacturer guidelines when working on electrical enclosures or control panels.
