Duck, the innovative emergency rope clamp. Conceived for single ropes with a diameter between 8 and 13 mm, Duck is the first and only belay device that works also on plane and tubular slings from 10 to 15 mm width (even if these are not certified for progression). Due to the small dimensions, it can be easily inserted even with one only hand. The big hole allows the rotation of sleeve connectors. Duck is born like an emergency rope clamp for retrieve, self-belay, progression manouvres and for regulations of daisy chains.
High quality product, completely conceived and produced in Italy!

awesome ascender

13 November 2014
This piece never leaves my rack. Had the duck for about 3 years now and its got so much use. Top roping. Rap down, weight the rope, and climb using the duck. Rescue. I use it in place of my waist prussick, and it runs alot smoother. A self locking belay when using a pulley. Weighs nothing, simple to use with one hand, and not one issue in three years! Cant beat that.
