Trango Big Bro #4

Trango Big Bro #4

The Big Bro #4 is a specialized wide-crack protection piece built for offwidth climbing and just large crack placements where standard cams may not cover the range. Its telescoping tube design helps save rack space compared to hauling a pile of oversized cams, while still giving experienced climbers a wide placement range.

This #4 size is the blue version and is designed for larger cracks, with a listed expansion range of 7.5 in – 12 in (191mm – 305 mm), which is about a Black Diamond #8 cam, and has a listed weight of 338 g. It is a niche but useful piece for climbers who know exactly when wide pro earns its spot on the rack.
