The CM350 is a pedestal base to support a 1.5-in. IPS mounting pole. it can be used as part of temporary installations or for applications where a concrete foundation is not an option. The CM350, with shorter, 23-inch pedestal legs, is adequate for most applications. The CM355 has longer, 39-inch pedestal legs that provide additional stability for applications where the feet cannot be secured (e.g., to the surface of a roof), for extended poles, or for locations with high winds.
The CM350 can be used with the CM300 23-inch mounting pole, the CM315 47-inch mounting pole, or the CM310 56-inch mounting pole. When purchased at the same time as one of these poles, it is not ordered as a CM350, but as option -PS of the mounting pole part.
