Updated 06/30/2026 | Published 06/29/2026

Question:

what is the shaft size? Im reading conflicting info on your website. one section states 1/2inch shaft while another states 5/8. Several of the reviews conflict as well. Please confirm. Thanks in advance.

Hey Peter, sorry for any confusion but the Yates Spool Roller for Boat Trailers # YR410Y-4 that you referenced has a 5/8 inch diameter hole in the center of it. What diameter shaft do you have?

@Peter for a similar spool roller that fits the 1/2 inch shaft you would want the part # YR4163-4P instead.
