On their round grommets Marine East's description is by "inside" diameter not outside.Norseman wrote: ↑Fri Dec 01, 2017 5:06 pmDid not see the excact same grommets that was on my boat: 4”, 2 Piece, 4 holes on the Marine East page: Similar looking, but it did not say 4” outside diameter, unless I missed it, or previous owner changed the grommets along the way.. Marine East were the original OEM rod holder grommets used by Albin:
For future reference, the part# is 6660W.
Another reference for LED bulb replacement is Marine Beam. A good company with lots of selection. I replaced all cabin halogen bulbs on my 28 and 31 with varios LED's from them. Some in white/red, some in white/blue all within the single toggle switched lamps. They also had options for the 31 cabin reading spots.
Great job on updating and caring for Odin!
