Anyone know where to get them

If you can not find it. A while back i went to a plastic place and bought a piece, not sure how think it was? 3/8 ? stopped by a cabinet maker and he cut grooves in it and routed the sides. it was easy. Good luck, Greg

A strip of SeaDek works awesome as well. Maybe SNSTER can post a pic of his.

As Jawbreakerkid said I used a strip of sea deck that matched the floor and had the boat name put in it. I really like it. I did have it redone so the name faces out now though.
