Ear covers and hubcaps
The enclosure is equipped with a plastic ear cover on each of the ears located on the front panel. A hubcap, in turn, fits
over each of the ear covers. Slots at the base of each cover's inside face receive the mounting nibs on each end of the
enclosure bezel. These mounting nibs insert through the respective slots of each overlaid ear cover and hubcap
assembly. The enclosure can operate with or without the bezel attached, but the ears should be fitted with both sets of
covers at minimum. Figure 42 callouts apply to the table portion of Figure 41. The front view of the enclosure bezel
shows the assembled components.
