Lewmar ocean sizes are 19mm, 23mm, 30mm and 35mm so maybe not Lewmar although their T track are different widths.
Different brands of track and even different ranges within one brand are all different cross sections. Any replacement really needs to match the existing track. A photo might clarify.
Yes I have a good spare pair, above and beyond the spare ones on board , I use 16mm sheets on 1 and 1/4 inch track , they are big ‘uns though !
Perhaps someone can advise on their fair pricing used , pair?
Will photo and pm you
