Product Description The CMS115S focuses on speed of installation, giving integrators a ceiling plate that connects quickly while maintaining a clean overhead appearance. Its low-profile design sits close to the ceiling for an unobtrusive look in conference rooms, classrooms, and commercial meeting spaces. Integrated cable management allows cabling to exit the top of the plate through a dedicated cable exit port, concealing wiring within the mount assembly. The plate incorporates Chief's All-Points Security System, with exclusive locking hardware at the column connection point to protect equipment against theft. Aluminum construction delivers optimal strength in a lightweight package that is easy to handle during installation. The 1.5" NPT compatibility means the CMS115S threads onto standard Chief CMS columns and accessories, integrating into the broader ceiling mounting ecosystem.
