***UPDATE. They rusted and broke again. SEE MY PHOTOS! ***Had to buy all new equipment because what they were using was complete rubbish. The nuts weren't tight (the clasp fell out in my pocket) so I replaced all the nuts with nylock nuts. go to the hardware store and ask about the cost. A little disappointed. Update: One of the through bolts has already sheared off and needs to be replaced as well. just trash.
