Since the reader has several holes on the top and bottom for mounting, knowing the exact dimensions is not required. You tell your equipment dealer what projector you have and they should know how to mount it. Or you could tell us here, and we can help you. If you think you need to make your own custom adapter plate for a special reason, you should contact Dolby directly to get exact dimensions. They are very good about that kind of thing and I sure it would be no problem. Some people like to keep the magazines on the projector, but with a Dolby and DTS reader stacked up, it gets to be a tricky mounting. Mostly, it seems that the firetrap rollers get in the way somehow. You might want to consiter a mounting bracket that Kelmar makes, where one 'standard' bracket is mounted on the projector, and you insert the one reader you need.
Look at: http://www.kelmarsystems.com/page19.html Most Dolby readers are mounted such that the reader is 'closest' to the projector, since a Dolby reader is much larger. (You apparently are not using SDDS an all.) For example, (if you also had DTS) the film would pass through the DTS reader, then the Dolby. I have heard of problems when the film is threaded through both (DTS and Dolby) readers, and you are running DTS. It does not happen all the time, and depends of what kind of projector, etc. The film 'bounces' while going through the Dolby reader and the slight speed variations screw up the DTS. So you might want to try it and see. If so, perhaps you can figure out a way to thread only the DTS reader when needed. There are many different projectors, mounting methods, and so forth that unless you tell us details, it's tough to suggest a good solution. Is the booth ceiling low? At a place I know, after they mounted a DTS, Dolby and an SDDS, the reel arm would hit the ceiling. They had to cut it shorter. Is the projector on an steep angle? Same thing as above, only the magazine hit the wall. They couldn't pull the projector away from the wall, because the port window was too small and high. So they got that Kelmar bracket.

I, personally, don't like running through multiple readers. It just irks me. Takes longer to thread too (I'm kinda lazy). Sort of a play off "Don't put all your eggs in one basket" I wouldn't want to see a brain wrap yankin' any more rollers than necissary.We use The Docker that John Walsh mentioned. However we also mount our digital processors on moveable soundracks and connect them with Digital Interface Kits. It's a bit more expensive than permanently mounting processors and readers, but offers the ultimate in felxibility, which I think is the point of multiple reader formats. ------------------
