The Vibration Reducing Adapter (PP-VIB) absorbs vibrations from outside disruptions to keep the display image steady. Large rubber dampers inside the PP-VIB absorb shock caused from outside activities such as slamming doors or equipment motors. This adapter includes an integrated coupler that fits any 1.5” NPT pipe (not included). Attach the adapter to any ceiling stud, solid ceiling surface, or Premier Mounts’ PP-FCMA ceiling adapter, secure the 1.5” NPT pipe (not included), then install the mount to the pipe.
