bottom opening of the bracket.
The bracket attaches to a 1" to 2" diameter projector

mounting pole. Its low, 2-inch height allows it to be
mounted in tight spaces between the projector and the
ceiling, while its depth of 8.75" enables it to
accommodate a variety of device sizes.

Mounting to the Projector Pole

Mount products on the PMK 250 bracket as follows:

1. Remove the front panel from the PMK 250, using an
Extron Tweeker (provided) or other small Philips
screwdriver. (Retain the four screws to reattach the
plate when finished.)

2. Remove the protective backing from the self-adhesive rubber pad,
and place the pad on the PMK 250 mount plate, centering it between
the two holes (see drawing at right).

3. Remove any rubber feet from the bottom of the device(s) to be mounted.
