Trango B-52 Belay Device

We took Saint-Exupery's philosophy to heart as we designed the B-52™. Free of rings, eyelets and other quackery common to other belay devices, the simple elegance of the B-52™ will appeal to the climber looking for a single device which can handle all her trad climbing needs.

The rockered bottom of the B-52™ allows you to stop falls with solid authority, regardless of what rope diameter you’re using, while still allowing an almost frictionless and jam-free feed. Additionally, it’s next to impossible to get a rope jam when you’re feeding rope, so short-roping your leader is a thing of the past.

Rappelling with the B-52™ is a thing of beauty. We’ve all gotten used to the jerky-at-the-top/terrifying-at-the-bottom rappel sequence offered up by most belay/rappel devices. The B-52™ changes all that with extremely smooth starts and controlled descents all the way down.

For advanced climbers and guides doing multi-pitch routes, the B-52™ can be used as an "autoblock" device that will assist in locking up the rope when the leader is bringing up a second. And in a pinch, the B-52™ can be used as an emergency ascender. The carrying cable is sheathed in a tough nylon-6 housing that won’t abrade through after a couple of climbs and is stiff enough that it won’t get sucked in to your rope.
