The cast aluminum Ball/Truck Combination gives a very pleasing and durable top appearance to any internal rope flagpole. Constructed of cast alumiunm, these units utilize duals stainless steel, sealed lubricant bearing assemblies for longer life and greater ease of rotation, internally mounted stainless steel pulley blocks and bronze cable bushings. The standard sized unit, similar in appearance to the External Halyard Cast Ball/Truck assembly, is 7 3/4,” Please call to order a 10″ diameter or the large unit has a 12″ diameter. The spindle is of machined cast aluminum with 1 1/4' NPT threads.
*** NOTE – 1 1/4 inch National Pipe Thread will actually measure 1 5/8 inch on a tape measure.
