The Panasonic ET-PFD550 Projector Stacking Fly Frame is a professional-grade mounting accessory designed for large venue installations and rental/staging applications. This frame provides a robust and secure method for either flying (suspending) projectors from overhead rigging or for stacking multiple projectors together to achieve enhanced brightness or redundant operation. It is explicitly designed for use with specific high-lumen Panasonic 3-Chip DLP projectors, such as the PT-DZ21KU, PT-DS20KU, and PT-DW17KU series, ensuring a precise fit and optimal alignment.

A key feature of the ET-PFD550 is its integrated adjustment system, which allows installers to fine-tune the projected image without needing to reposition the entire frame. It offers front left and right height adjustments, providing approximately 5 degrees of vertical tilt, and the ability to swivel the back of the projector from left to right by approximately 5 degrees. This 3-axis adjustment capability is crucial for achieving perfect image convergence when stacking multiple units or aligning a single projector on complex screens.

The frame is engineered for ease of use, with no additional hardware needed to attach a second frame for dual stacking configurations. For hanging applications, an optional truss mount hardware accessory (ET-PFD550TMS2) is available. Built from durable materials, the frame is designed for static, non-moving installations in professional environments and has a net weight of approximately 41.89 lbs (19 kg).
