The CM340 kit uses j-bolts to attach a mounting pole (CM300 series or user supplied) to a concrete base for permanent installations where there is a need to periodically plumb the pole. Nuts on the j-bolts are used to adjust the pedestal and pole, and are then locked in place with additional nuts.
The CM340 can be used with the CM300 23-inch Mounting Pole, the CM315 47-inch Mounting Pole, or the CM310 56-inch Mounting Pole.

Several pedestal options are available to fit individual applications. They can be ordered as options to the CM300-series mounting poles or as separate items.
