The tool he used looked to me like a Paladin 1545 All-In-One Telco
Tool.The new connectors he installed (using that same tool to remove the
old connectors and install the new connectors) have a black insert
inside the barrel of them.I guess some sort of soft insert which makes
them weather tight.
I reckon y'all know more about that stuff than I do.
