In applications involving a tower and either strong winds or the need to attach a lot of gear to a crossarm, Campbell Scientific recommends using a longer crossarm with a second CM210 Crossarm-to-Pole Bracket. (One CM210 ships with each CM202, C204, or CM206 crossarm.) Secure the crossarm to two points on the tower to add stability and rigidity to the crossarm. The crossarm can be shifted in a foot (the distance between the vertical supports on the tower), or the crossarm can be centered on the tower.
