This is a replacement ferral for the always missing arrow to rod bushing, Solid brass total length is 2 5/8 long with 2 " gernal for the arrow to pivot on, it has a slight taper on the 2 " gernal 7/8 at top to 29/32 at the bottom. The inside measurements will fit a 3/4 rod, these are hard to find pieces for your arrow weathervanes,,, please look at the pictures I have done my best to describe it, PLEASE LOOK AT ALL THE PICTURES FOR BEST DISRUPTION. THATS A 5/8 " ROD I AM USING AND IT WORKS GREAT,,
