diameter of 1 to 1.75 inches. The SnowVUE 10 mounting kit attaches directly to the crossarm or
pipe.

Figure 7-3

(p. 12) shows the SnowVUE 10 mounted to a crossarm using the mounting kit. A

U-bolt mounts the bracket to the crossarm, and two screws fasten the SnowVUE 10 securely to
the bracket.

The SnowVUE 10 mounting stem (

Figure 7-4

[p. 13]) attaches to the crossarm using the 1-inch × 1-

inch Nu-Rail fitting (

Figure 7-5

[p. 13]), CM221 right-angle mount, CM230 adjustable-angle

mount, or CM230XL extended adjustable-angle mount. Use the CM230 or CM230XL if the
ground surface is at an angle.
