Thanks for all the input.
We are talking 20-30' from an I-Beam and going to throw it about 20' to a screen. With this distance, and for keystoning purposes, would it be better to do a motorized projector lift or stationary mounting?
Apparently there is already
electric outlets available up there.
Chief Manufacturing has I-Beam brackets.
And as for signal, we have yet to even pick out a projector.
