The XMU attachment kit is designed to position the Phoenix lens in front of the primary
lens of most projectors which have already been ceiling mounted with the Chief RPA
with either the universal or SLB projector adapter (Chief parts not included) per the
manufacturer’s instructions and where the projector lens center is no greater than
4” (100m) to the left or right of the center of the ceiling mount pole. If you have not
yet purchased a ceiling mount for your projector, the Chief RPA with SLB is generally
the easiest to work with since it requires the least adjustments while installing the XMU
Attachment Kit.
Please note that if you are using the universal Chief projector adapter you should take
care to set up the arms per the manufacturer’s instructions so that the mounting pole is
at or just a little in front of (ie toward the screen) the center of gravity of the projector for
best balance.
