This item is used on multiple models.
DO NOT confuse this with the key#233 handle cap (also called closed bearing cover) that goes on the opposite side of the handle.
THIS is the key #226 cap that goes on the back end of the reel.
This part is originally for the FRC5000 and FRC6000 (226-5000FRC has a Shiny Finish)
Can also be used as a substitute for the BTL5000, BTL6000, SG5000 and SG6000 (226-5000SG had a Matte Black finish)
They are otherwise identical except for the cosmetic difference.
