Has anyone used the Chief RPA-225 for mounting the PT-L300U to the ceiling? I need to mount it as I need off the coffee table. I tried positioning it to the side and using the keystone correction. It didn't work. I understand that keystone correction degrades the picture quality. So, don't want to use it.


My ceiling is 9' tall. I looked at the Chief RPA-225 and it doesn't seem to hang much farther from the ceiling. I don't know if I need to use a steel pipe or something to hang the projector down lower. At 9' feet height, is there a specific distance from the ceiling the porjector needs to sit? Do I need to have it 1' down from the ceiling or anything like that? I am trying to get an idea, so after mounting it on the ceiling, part of the picture won't up on the celing itself.


I see that on the bottom of the pj, there are some grooves, that look ready to accept bolts. Does the Chief RPA-225 use those? I don't want to drill anything into the projector.


Thanks for the help.

I purchased a PT-L300u about a month ago and love it.


To mount it in my media room (I have nine foot ceilings as well), I purchased the Chief RPA-225. It matches up perfectly to the projector. No worries at all there.


I also purchased the CMA-100 which consists of a ceiling plate and an adjustable column from 24" - 46" in 3/4" increments.

Information about the CMA-100 from the Chief web site


I like it. It is extremely professional looking and very well built.


It works really well for me as it gives me the right height.


Best regards,


Burbub

What is the height of the Projector from the ceiling? If I were to use the CMA-100, the minimum distance between the projector and the celing is 24+ inches, right? Did you fnd that not using a column to hang the projector down from the ceiling caused problems when projecting? I am trying to understand the distance between the ceiling and the lens. I would prefer to flush mount it if the projector can project down. I don't want to use any keystone correction due to my fears that it will make the picture worse. Thanks.
