This is a custom line roller for the 04 Certate. Compatible models: 2000 2004 2500 2506 2508R I haven't confirmed compatibility with models 3000 and up, but it probably won't fit. This item has more signs of use than the other one I'm selling, so I'm offering it at a lower price. Some discoloration of the anodized finish can be seen, but there are no snags on the line, so I don't think there will be any problems with actual use. The line roller on the 04 Certate is a weak point, and the C-clip spring rate is high, making bearing replacement extremely difficult. Therefore, I used a bearing clip from a Daiwa bait finesse reel to make replacement easier. The bearings used are new stainless steel cast top rust-resistant bearings (in my opinion, they make less noise than CRBB bearings). Replacement is easier than with a C-clip, but be careful when removing it, as it can fly off if not held down properly. It's pre-assembled so you can just swap it in. Please use it for maintenance.
