Outdoor distribution point units feature either aluminum or plastic bases, brass terminals, and drawn aluminum or plastic covers. The mounting brackets are made of formed aluminum.
Aluminum covers have a stainless bead chain affixed to the mounting brackets to prevent cover loss during servicing.
1-pair outdoor distribution point units are used for open wire circuits and long drop wire runs. The 5500 series are for use on 1-pair open wire, RDW (Rural Drop Wire), or figure 8 service drop applications.
