Mammut Nordwand Alpine Belay Device

For reliable and versatile belay and rappel performance without adding extra weight, we look to the Mammut Nordwand Alpine Belay Device. The grooved steel inserts create more friction for reduced strain when braking and lowering while also increasing durability and minimizing overheating. When belaying from above, the guide mode lets us rig an auto-blocking system for increased safety and comfort.
