Product Overview
The CHIEF CMS491C is a 1x2 AV ceiling enclosure designed to simplify and enhance mounting solutions in modern AV installations. Featuring a white finish, this enclosure is specifically tailored to fit within standard 1x2 ceiling tiles, offering clean and professional integration in commercial and institutional settings.
