I've searched the Archives and was unable to find a discussion on the spreader dimensions and parts. I believe they are 1" O.D. and therefore should be 7/8" I.D. but am not sure. Can anyone verify. I need a spreader tip. Is this a standard or do I have to go to Edenton? Rig-Rite has a selection of tips but don't know they will fit the Rhodes spreader.
