Both Strick and I used the Taco # V21-9613 which can be found here:

But this is a rigid vinyl rubrail that requires the stainless steal insert # S11-4511
I would have used a soft one but couldn't find much info. When I contacted rubrails.com they never got back to me (found out their computers got hacked and were down for a while but back up and running now). I would recommend calling them or hamilton marine.
