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.\u003c\/p\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003cp\u003eInjection-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.\u003c\/p\u003e","brand":"Atlas Sound, L.P. - Mitek","offers":[{"title":"Default Title","offer_id":52445833855160,"sku":"19388","price":21.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0871\/7382\/4696\/files\/19388_ATLAS-SM42-52KNOB-B_ALT01sqr_156e12ae-e86c-4d12-b962-2f4fdeb13f8d.jpg?v=1783453416","url":"https:\/\/soundpro.com\/products\/atlasied-sm42-52knob-b","provider":"SoundPro","version":"1.0","type":"link"}
