The PG3AW Extra Large Projector Guard Security Cage from Chief helps secure the projector from theft and protect it, for example if installed in a school gymnasium. It is suitable for projectors up to 11.36 x 25 x 24.9" in size.
In addition to the cage, a mount that is compatible with your projector is required (available separately). The PG3AW is compatible with RPA and RPM series mounts from Chief. These projector mounts in turn feature threading for standard 1.5" NPT pipe. Ceiling plates that use 1.5" NPT pipe include the RSM and RSA series from Chief.
