My theater is relatively new (4 years) and when the projectors were installed, some moron installed interlock capability on our two smallest houses in each booth. Last year i decided to go ahead remove them and reinstall them to connect the two largest houses in each booth.

The downside about our mounts is that they go into the wall. So film has to run along its closest wall. (or dart across the booth to a wall)

I've been trying to find where i can get rollers that 'hang' from the ceiling, so that the film can run through the center of each booth. I've seen 'em, but haven't had much luck finding 'em. Anyone know where I can get a hold of some?

Have you tried your service outfit? Kelmar, Speco and even Strong all make film guidance roller assemblies that can be adapted to mount from the ceiling. Just be carefull when doing it to a drop ceiling. You will need to reinforce it from the top somehow. I believe Kelmar also makes a Floor standing setup on a telescoping tripod. You could also simply use your make-up table (depending on design).
Something to keep in mind, is that depending on your automation setup, there may be more involved than simply putting up some rollers to get it to work.
As an aside, interlocking the two smallest houses isn't that bad an idea in my opinion. Lets face it, how often are you going to have a film so big that it will fill both of your biggest houses? If you did have a film that big, chances are you'd get more than one print for more start times and so as to not have a traffic jam in the lobby at intermission. Whereas if you had a film that did unexpectedly well, you could move it to the interlocked houses and sacrifice one film that is doing badly, and not worry about tying up that many seats.

SPECO and Neumade are the two companies we've ordered through in the past. We have several suspended rollers installed on the ceiling throughout the booth, as well as pivoting rollers mounted to the tops of a couple platter trees.

I have had good luck just using any rollers I can find and suspending some of those green bars, like what they make shelves out of at some stores. Point is, suspend something else, then attach rollers to that.

I do hate those rollers along the walls, I feel much more confident when they are hung on the ceiling.

Goldberg makes the best rollers for interlock purposes. They don't have the large gap between the keeper and roller flange like the Kelmar and Neumade's do (even though they look virtually identical). As such, even if you are turning the roller sideways, the film will NOT fall out.

Plywood "ceiling tiles" work great for this. Just remember to make sure they are slightly less than 2x4 feet and you jigsaw off the corners by about 1/2 inch. From that point you can secure the roller brackets via drywall screws.

Brad makes a good point, one of my suspended SPECO rollers, the one after the tensioning arm does tend to use the increased tension to ride against the keeper roller instead of the big roller. Glad to know that there's an alternative.

We simply use free-standing roller systems (similar to a variac) that can be transported very easily.
