Small yet mighty, the Duck is a game-changing emergency rope-clamp and super-compact belay device from Kong. The Kong Duck is the first and only belay device that works with single ropes, as well as plane and tubular slings. All this, plus it is so small that it can be easily inserted with one hand for efficient use. Weighing only 70g, you would be "quackers" not to own one of these versatile, and extremely handy devices.
