Built with an expandable tube chock design, it saves on both weight and racking space compared to cams in a similar size. Simply place a Big Bro in the crack, push the button to extend it to the right size, and twist the sleeve to lock it in place. They also resist pull in any direction, adding to their security and your confidence as they are nearly impossible to accidentally dislodge as you climb past them. If you are looking for something new and versatile to add to your rack, look no further than the Big Bro Rock Climbing Tube Chock by Trango.

Free Shipping. Trango Big Bros The Big Bros by Trango are the biggest, lightest wide crack protection on the planet. Named after George Orwell's book, 1984, in reference to Big Brother watching, Big Bros were designed by Craig Luebben as his Senior Design Project while an engineering student at CSU. Watch him stringing a line of these and you'll never even know he's not plugging cams. Big Bros are happiest when placed in parallel sided cracks (think Utah sandstone) but, with practice, you can find secure, one-handed placements in a variety of crack geometries. The #5 Big Bro will protect up to an 18in. splitter and the smaller sizes are great lightweight replacements for your fist-sized cams.
