Overview
The CMB200 Crossarm Brace Kit is designed to provide additional stability to the CM203, CM204, or CM206 crossarms mounted on Campbell Scientific tripods and towers. This kit provides support for crossarms with heavier or sensitive sensor loads, as well as added stability in higher winds.
The CMB200 can ordered with an optional black powder-coated finish. This finish helps with reflections when using the CMB200 to mount solar radiation sensors or other light-sensitive sensors.

Detailed Description
Each kit includes one brace arm and three sets of mounting brackets:
- The small bracket (pn 31593) attaches the brace arm to a UT10/UT20/UT30 tower leg.
- The medium bracket (pn 31592) attaches the brace arm to the CM203/CM204/CM206 crossarm.*
- The large bracket (pn 31594) attaches the brace arm to the CM110/CM106B tripod mast or UT10 tower mast.
