Peerless-AV's Heavy Duty Projector Mount is designed to simplify the installation and alignment of heavy, large venue projectors. The Hook-and-HangTM feature provides a large landing area when securing a projector to the mount. The tilt, roll and swivel features are all lockable to prevent even the smallest shift to the image. Dedicated adaptor plates are made for each OEM projector manufacturer and are designed to place the center of gravity in the center of the mount, making adjustments effortless. Universal mounts are not recommended for these heavy projectors as they can be difficult to balance which can lead to projector sag over time.
