The top of a pole should always be protected either by a sheet-metal flashing or by a cap. A flagpole cap, with regulation ball, is shown in Fig. 56, which is a detail of the cap shown in Fig. 51. A brass casting a fits snugly over the top of the pole and is secured to it with brass screws. An eyebolt at the left holds the flag pulley. A piece of brass tube b joins the cap to a brass spud c which is soldered to a seamless copper ball. This style of cap not only protects the pole from the weather, but provides a suitable pulley connection, and gives an artistic treatment to the apex of the flagpole.
