A:AnswerIn the product description it states that it is compatible with most projectors however it does not specify specific models. It should be universal which means it should work with the 9300i. Good luck.
A:AnswerSince it is a Universal mount, I would think it would work. I have an ACER projector and this mount works just fine. You can purchase and before you try mounting to the ceiling, just test-fit the holes on your projector to the arms on the mount.
A:AnswerHello Sammyjf. The Universal Projector Ceiling Mount Kit includes a 3" extension bracket. Unfortunately, Epson does not make anything longer for the mount kit. Regards, Kevin - The Epson Team.
