Notes
When stacking projectors, the
stack MUST be vertical, to
ensure that the stresses are
distributed to all for frame
couplings.
Make sure that the surface,
ceiling or rigging that is to
support the projector is
capable of supporting the
combined weight of all the
projectors and lenses (see
specification for weights).
Do not place heavy objects
on top of the projector
chassis. Only the rigging
frame is capable of
withstanding the weight of
another projector.
Do not try to stack more than
four projectors.
Separate backup safety
chains or wires should
always be used for each
projector.

Stacking projectors
The rigging frame is capable of supporting the weight of up to three other projectors,
using the built-in frame couplings. The projectors can be stacked on top of each
other, or suspended below each other.
• Carefully lower each projector down onto the top of the others, making sure that
all four frame couplings engage fully.
• Fit a locking pin into each coupling. A ball in the end of the pin prevents the pin
from falling out – to insert or remove a locking pin, press the button on the t-bar
to release the ball.
• Align the images from the projectors, following the instructions in section
3. Getting started, Adjusting the projected image.
