The Kong Duck is a compact, one-way rope clamp for ropes from 8 to 13 mm. Specifically designed for professional applications such as rope access, industrial positioning and technical rescue. Under load, the device locks in one direction, while it can move freely in the other direction for optimal freedom of movement and ease of use. The Kong Duck complies with EN 567:2013 and UIAA 126:2018 standards and is part of a system that protects against fall impact when working at height. Suitable for vertical positioning, lifting loads (WLL 400 kg) and as a length adjuster for lanyards on safety harnesses. Not suitable for use as a fall arrest device according to EN 363.
