2.1 Filter Holder Mounting Instructions
If the collimator housing has an accessory tray, the two 9" x 3" x 1/16" acrylic mounting plates (held
together by four screws) should be cut to fit the rails of the tray (Figure 2-1). If the tray channel is less
than 1/8" wide, only one of the mounting plates is required. The other should be removed and retained as
a spare.
If the collimator does not have an accessory tray, the filter holder can be mounted with self-stick Velcro®
tape. The Velcro attachment kit (57-426-1100) is available.
To separate the filter holder from the mounting plate(s), remove the four small screws holding them
together (Figure 2-2). Carefully measure the collimator’s accessory tray and mark one or both of the
mounting plates for cutting. A cardboard template is recommended as a cutting guide. Make a trial fitting
with the template before cutting the plastic to ensure that the filter holder will be in the proper position on
the mounting plate. If the final shape of the mounting plate is not square, be sure to check for proper
longitudinal orientation of the filter holder (Figure 2-1).
