This kit allows a Campbell Scientific enclosure to be mounted to a CTS tower. The 21895 includes three 30"-long aluminum pipes, two 21261 Bracket Sets, and two CM220 Right Angle Mounting Kits. In a horizontal position, two pipes are attached to the tower using the 21261 brackets. The distance between those pipes must be less than 30". The third pipe is fastened to one end of the other pipes via the CM220 mounts. A Campbell Scientific enclosure with a -TM tripod mast mounting bracket can then be mounted to the vertical pipe.
