Seachoice External Eye End Top Cap Nylon.OD 7/8" OD Color White. Two per package.
I have to replace these every 2-3 years because they are plastic. They work well. Getting the old ones off were a bear because they are in the end of the bimini top tubing very very tight. I should upgrade to stainless, but for the cost I can't complain. Only giving these a 4-star because they are plastic.
