|---|---|---|
| 21.0 | 21.0 | 124 |

**Exact dimensions.** True size, with no printing tolerance added.

## Notes

- Fuji's DPS is the standard pipe-style graphite spinning/casting reel seat; the size number (18) is the nominal seat size, not the bore.
- The bore of a size 18 seat is 18.0 mm, so the blank plus arbor/shim must build up to 18.0 mm at the seat position.
- The model is the published body tube only. Hood geometry, nut OD and thread pitch are not published in the size chart.
- Numbers are from Fuji's US distributor Mud Hole, because Fuji's own site could not be reached; marked secondary.
- True size, no printing tolerance added. Only published numbers are used; anything not published is said so.
- Secondary source: the numbers come from a retailer or magazine copy of the maker's specification.
