Gibraltar ALH-25M-G Lobed Knob 4-point Aluminum

Product Description

The GIBRALTAR ALH-25M-G is a 4-point lobed knob machined from 6063-T5 aluminum, designed for hand-tightening and manual adjustment applications across industrial, mechanical, and equipment assembly environments. With a 63.5 mm head diameter and a 25 mm hub diameter, this knob provides a firm, ergonomic grip for frequent or tool-free fastening. The 6063-T5 alloy offers a solid balance of strength and corrosion resistance, making it suitable for use in light industrial settings. Technicians and assemblers install this type of hardware on panels, fixtures, jigs, and machinery requiring repeatable manual adjustment.

This lobed knob is suited for general industrial and mechanical assembly applications where a standard threaded hub knob is needed for hand-operated clamping or positioning. It fits residential and commercial equipment panels, test fixtures, and industrial machinery. The 4-lobe design allows secure grip without tools, making it a practical choice for service panels and adjustable mounting hardware encountered by electricians, equipment installers, and maintenance technicians.

Key Features

• 4-point lobed profile for ergonomic, tool-free hand tightening
• 63.5 mm head diameter for a wide, comfortable grip surface
• 6063-T5 aluminum construction balances strength with corrosion resistance
• 25 mm hub diameter with 14.3 mm hub height for secure fastener engagement
• 28.6 mm overall height suits standard panel and fixture mounting depths
• Lightweight at 0.14 pounds, reducing added load on assemblies

Compatibility

Designed as a standard lobed knob replacement or new-installation component for industrial panels, mechanical fixtures, and adjustable equipment assemblies requiring a 25 mm hub interface.

Installation Notes

Installation is typically performed by maintenance technicians or equipment assemblers using standard hand tools. Ensure the mating threaded stud or insert matches the hub bore specification before installation. Power down or de-energize any associated equipment before servicing panels or assemblies where this knob is being installed or replaced. Do not overtighten beyond hand-tight unless the application specifically requires a tool-assisted final snug.
