Don,
The pole will be used at the NAs 11-14 September and is available after that.
The inside diameter of the carbon pole is 2.5 inches and can accommodate alternate end fittings. You should insulate any metal fitting used with a collar to prevent electrolysis at the carbon interface. The Forespar end fittings are UXP-200EF composite and isolated with a collar part number Forespar BU-200-250. The screws used to hold the assembly together are stainless pan head with nylon washers under the heads to prevent the SS from contacting the carbon. The screw holes in the pole are slightly larger than the screws. The end fittings are tapped for the screws.
