This is the bushing for the Forte Carbon Tube 225 (FTC 225). Forte applies 4-axis continuous fiber braiding over an aluminum mandrel to produce extremely durable and tough carbon fiber tubes. The interlocking fiber braid is wet-out with epoxy resin. The end result is a seamless braided tube with very precise compression or bending characteristics.
This bushing allows the use of 2 inch forte spinnaker pole ends in 2.25 inch I.D. tube.
