[HELLSTER INC.]

I used 1/2" sch40 pipe for the insert then put a piece 1" sch40 pipe over that from the top of the sail mast up 3". Use 20mil pvc tape to make it fit snug.Then a end cap with a screw threaded thru. The 1 " pipe ads stability and just looks better! Then prayed it with a rubber coating. Works like a charm.
