Hey Brazil, we test 6 Grampo P bolts. Robelois donated them and Rodrigo Moota told us the welds are unreliable and the carabiners could unclip but they are everywhere in Brazil so lets find out how strong they are. They are installed backwards because the force should not really be applied to the unreliable weld.
