Electro Hardware A3534 Round Aluminum Handle Knob

Product Description

The ELECTRO HARDWARE A3534 is a round plain-finish aluminum handle knob designed for use on panels, enclosures, instruments, and light machinery. It features a 2-inch center-to-center measurement, a 1.5-inch projection, and an 8-32 thread size. The aluminum construction keeps weight low while providing reliable grip and corrosion resistance in typical indoor applications. This style of knob is commonly installed by electricians, panel builders, and instrumentation technicians during equipment assembly or field service work.

The A3534 fits standard Series A knob applications where a compact round profile and plain finish are specified. It is suited for residential and light commercial control panels, electrical enclosures, and instrument housings that require a threaded-post knob with an 8-32 thread pattern. The plain aluminum finish is appropriate for environments where an uncoated metal appearance is acceptable or where a secondary finish will be applied after installation.

Key Features

• Round knob profile with plain aluminum finish for clean, functional appearance
• 2-inch center-to-center measurement for precise panel spacing
• 1.5-inch projection for comfortable grip and positive actuation
• 8-32 thread size compatible with standard threaded post hardware
• Aluminum construction for lightweight, corrosion-resistant performance

Compatibility

Designed as an OEM-style replacement or new-installation knob for control panels, electrical enclosures, and instrumentation equipment using 8-32 threaded posts with a 2-inch center-to-center requirement.

Installation Notes

Installation is typically performed by electricians or panel assembly technicians. De-energize all circuits in the enclosure before removing or installing knobs on live panel assemblies. Verify that the existing threaded post matches the 8-32 thread specification before installation. Hand-tighten onto the threaded post and confirm secure seating before returning the panel to service.
