The 45B is for adapting a plumbizer to a mast arm pole by using a 1-1/2 in. nipple threaded into the pole. It makes for a very clean look on the mast arm pole without the use of pipes holding signals. When using the 52CA cluster adapter the 45B Extended (45BE) must be used to allow enough clearance for rotational adjustment. The 45BE uses a 3” nipple for the extra clearance.
