It can fold nearly flat for travel, and allows room for changing the lower projector slide tray after it is all set up. Adjustments for alignment are made by physically moving the stand, and by changing the elevation controls on the projectors. Made from black-finished aluminum by Da-Lite.

Simple to use, you just plug the remote control cords into two, three or four projectors. Then a single Carousel^® remote control may be plugged into the socket on the box, and the forward and reverse functions of the projectors will all occur simultaneously! There are separate control circuits for each projector, to prevent any interaction that might cause damage to the projectors. Other control devices, such as a projector control cable from an Audio Visual synchronized tape recorder, may be plugged into the box for multi projector synch control. The handy illuminated forward and reverse control buttons on the box itself may be used for manual control, if the remote control has been forgotten. So easy to set up, and totally self contained, the box receives its power from its connection to the Carousel^® or Ektagraphic^® projectors. 

The system may be used with other projectors that use the same EBY 5-pin plugs as the Kodak remote controls, but a separate power supply (not included) may be needed.
