Product Overview
The Chief PG3A is an X-large projector security cage that fully encloses a projector and its mount in a locked steel enclosure. It protects valuable projectors from theft and recreational damage in open and high-traffic spaces. A hinged door and adjustable front opening keep the projector accessible and serviceable. It installs over pre-existing mounts without disturbing projector settings.
Product Description

The PG3A is a top security solution that fully encloses the projector mount in a locked steel cage to prevent theft as well as recreational damage. It is a practical safeguard for an auditorium, house of worship, training room, or other commercial space where projectors are exposed and costly to replace. The PG1 through PG3 guards are compatible with Chief RPA and RPM Series projector mounts, while the larger PG4 supports the VCM and VCT series. The cage can be installed over pre-existing installations without disturbing projector settings, so you protect equipment without recommissioning. An adjustable front opening accommodates different lens positions, and a hinged door provides easy access for maintenance. The enclosure accommodates roll, pitch, and yaw adjustments so the projector can still be aimed correctly. It locks with security screws, and optional padlocks add another layer of protection.
