Trango BigBro(TM) Expandable Tube Chocks are must-have pieces for wide cracks. Their huge range and sleek design save on weight and racking space compared to large cams.

- REI

Trango Big Bro climbing protection is built with an expandable tube chock design to protect your scared, groveling carcass when cracks grow to offwidth and squeeze-chimney sizes. Get the weight off your shaky fist stack, stick 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. Since Big Bros resist pull in any direction, they're nearly impossible to accidentally dislodge as you climb past. These unique protection pieces are lighter and easier to rack than similar sized cams, and they're the only hope for pro once you start climbing into chicken-wing sizes.

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.
