The KI-525 is a non-standard cutout size. How does the SN3308 install in this hole?
Sandel can supply a KI-525 Bezel Adapter which is used when the SN3308 is replacing an existing KI-525. The KI-525 is slightly larger than the standard ARINC cutout and has mounting screws which do not line up with the standard hole pattern. The Bezel Adapter covers the excess area and provides a neat, finished appearance.
