Gibraltar 5B60A210A8Z001G Lobed Knob 5 Point Black

Product Description

The GIBRALTAR 5B60A210A8Z001G is a 5-point lobed knob constructed from thermoplastic elastomer (TPE), designed for hand-tightening applications across industrial, mechanical, and equipment-service environments. With a head diameter of 2.26 inches and an overall height of 1.09 inches, this knob provides a comfortable, ergonomic grip without requiring tools. The 1/2-13 threaded bore with a 0.89-inch thread depth allows secure engagement on standard fastener stems. Electricians, HVAC technicians, plumbers, and equipment maintenance crews commonly use lobed knobs on panel covers, access doors, control enclosures, and adjustable fixtures where frequent removal and reinstallation are required.

This knob is suited for light to moderate-duty hand-adjustment applications in both residential and commercial settings. Typical uses include securing removable access panels, equipment guards, calibration fixtures, and instrumentation enclosures. The thermoplastic elastomer construction provides resistance to common shop fluids and oils while maintaining a secure grip in both dry and slightly damp conditions. Its compact hub profile makes it a practical choice in space-constrained installations where a full hex nut or wrench-driven fastener is not practical.

Key Features

• 5-point lobed profile allows firm hand-tightening without tools

Compatibility

Designed as a general-purpose replacement or service knob for equipment and enclosures using a 1/2-13 UNC threaded stem. Verify thread engagement depth against your specific application before installation.

Installation Notes

De-energize and lock out any equipment before replacing or installing control panel hardware. Thread the knob onto a clean, undamaged 1/2-13 stem by hand until snug. Do not use power tools or wrenches to drive this knob, as over-torquing can crack the hub or strip the threaded insert. Follow applicable equipment manufacturer guidelines and relevant safety codes for the trade discipline involved.
