Electro Hardware A3574-4 Round Aluminum Handle

Product Description

The ELECTRO HARDWARE A3574-4 is a round, black-coated aluminum handle designed for use in light mechanical assemblies, enclosures, and control panels. It provides a secure grip point for operators and technicians working with equipment that requires frequent manual adjustment or access. The handle features a 3-inch center-to-center spacing and mounts using an 8-32 thread size, making it compatible with standard fastener patterns found in industrial and commercial applications. The aluminum construction keeps weight low while maintaining adequate durability for repeated use in dry indoor environments.

This handle is suited for use on control panel doors, instrument enclosures, junction boxes, and similar equipment in HVAC, electrical, and light industrial settings. It is typically installed during panel fabrication or as a replacement on existing equipment where the original handle has worn or failed. The black coating provides a clean, finished appearance appropriate for professional installations.

Installation Notes

Installation is performed by electricians, panel builders, or HVAC technicians during enclosure assembly or service. De-energize any panel or enclosure before beginning work. Use appropriate hand tools to seat the 8-32 fasteners without overtightening, which can crack the knob or strip the thread insert. Verify the mounting surface is flat and clean before securing the handle to ensure even load distribution.
