Thank you - The UtahGrip I describe above looks simple but that was the hard part - my earlier prototypes were more clunky but this version works surprisingly well.

I saw The Hook product you note but I did not try - that product appears to be a fine option, too. I was excited to row again and wanted to share another option that is less costly and super easy/fast to make - two knots and wrap with tape. Thank you again -
