Trango BIG BRO's DetailsTrango

These puppies are big!

For fist crack and offwidth aficionados, Bigbros™ rule. The expanding tube chock design is stable, lightweight, easy to use and strong. Because of their stable nature when they're placed correctly they're almost impossible to dislodge when you're grunting by them, and they make a nice smooth rope guide at the lip of a roof. Their expansion range is phenomenal—a #4 BigBro™ has greater range than an entire set of traditional cams!
