AtlasIED SM42/SM52 Replacement Knobs for SM42T and SM52T | Black

Ceiling speaker installers and AV integrators working with AtlasIED SM42T or SM52T surface-mount speakers often need replacement mounting hardware to keep installations secure and code-compliant. These OEM replacement knobs provide a direct, manufacturer-matched solution rather than relying on generic hardware that may not fit or hold correctly over time.

The knobs are designed specifically for the SM42T and SM52T bracket system, threading onto standard 1/4"-20 fasteners to lock mounting brackets firmly in place. Sold as a pair, they cover a full speaker installation in a single purchase, reducing service call time and keeping spare parts inventory simple for integrators managing large-scale installed audio projects.

Injection-molded construction ensures consistent thread engagement and long-term durability in ceiling environments where access is limited and reliable fastening is critical. For facilities managers, low-voltage contractors, and system integrators maintaining or expanding AtlasIED speaker installations, these knobs eliminate the guesswork of sourcing compatible aftermarket hardware.
