The CMS491CP2 conceals AV equipment above ceiling tile and supports a column drop for mounting projectors within the same tile grid providing a clean professional look for classrooms and conference rooms. It provides a high-performance, dual gang housing, isolated ground, dual receptacle outlet featuring the SurgeX non-sacrificial multi-stage filtration and surge protection system. This protects equipment from disruptive high frequency noise and damage caused by power disturbances.
