BY2000 Byers' Super Snap 4 Pack Reusable Tarp Grommets

Eliminates need for gromets but can be hooked into gromet holes, too. I have hooked them to other tie-down hooks, too. They are a challenge to stick together until you get the feel for it. There is an easy way to do it. Check the manufacturers website for that. If left exposed to triple digit heat for a long time, it is best they not be stressed as the plastic can soften and also lose its memory for retention. I like them a lot. Frank
