Enclosure Options

Field enclosure that houses a CS476 or CS477 head. Typically the

#27162 Enclosure Mounting Kit is also ordered (see Accessories).

Accessories

#25619 - Bubble level that helps align the radar sensor in a vertical

position, which prevents measurement errors.

#25616 - Adjustment/Display Module used for changing settings,

testing, and diagnostics. A cap is available for this

display (see below).

#25654 - Cap with window for use with the #25616 display.

#27162 - CS476 and CS477 Enclosure Mounting Kit.
