I broke one of those the first and only time we put my friends up. You're talking about the plastic piece that you turn to lock it in place right? I looked all over camping worl and couldn't find one then one day while at a boat sales place looking for a boat part, guess what, there it was! I don't remember what it's called but I still have it new in the package. I need help on how to level a pop up. Any help would be appreciated! Thanks!
