It is 8.5 mm and fits snugly but still slides nicely in my old beat up rail!Here is the link, they sell it by the yard:perfectfit.com/15319/154247/Misc-Boat-Hardware/Keder-Awning-Rail-Insert.htmlIt's really cheap if you order a lot! Somebody might want to get get together and split it!Here is another site that I think some here have used. It is sold by the foot here:www.sailrite.com/Keder-Awning-Rope-Tape#.Uqnclic9k3N 5/16" (says it's 8.0 - 8.6 mm)Both sites sell the rail, too. The first site sells it in 8ft sections and the second in 4ft sections. Hope this helps somebody!!!
