Duck Tactical, the innovative emergency rope clamp by Kong. This mechanical ascender can provide you with incredible ease of operation when adjusting your lineman’s line or tether. This is a device that attaches to a climbing rope and slides smoothly in one direction but grips the rope tightly in the other direction. Think 21st-century prussic knot without all the hassle.
Wondering what to pair with your bad-to-the-bone 8 mm Sterling Oplux rope? The Kong Duck is the only mechanical ascender rated for use on 8 mm rope.
Conceived for single ropes with a diameter between 8 and 13 mm, Duck is also the ﬁrst and only clamp that also works on flat and tubular slings from 10 to 15 mm width.
The Duck only weighs 2.5 ounces. The big hole allows locking connectors to rotate 360 degrees and pairs perfectly with the Kong Oval Twist Lock from Wild Edge. Due to its small dimensions, it can be easily attached with one hand.
Duck was born as an emergency rope clamp for retrieval, progression maneuvers and for the regulation of daisy chains. The Duck is not certified as a fall-restraint device, so never allow slack in your rope while using it.
