[SML] projector mounts

[Richard John Archer]

We’ve got two nice Christie LCD  projectors….a few years old but like the present D series at 8K lumens  . Lots of zoom and key correction built in as well as blending.    Of course, as a theatre they are used in plays for scenic projection, in film for large screen , etc etc.   Needless to say they don’t just get mounted on the balcony rail.  Any ideas for a mount that will make focus easier given that for the way we use them they could be anywhere from straight on from out  front to straight down from above.  Something “portable”  and clampable to existing pipes and battens…..not a permanent ceiling mount. 
Thanks
