The Harken Ninja MultiAscend is designed to make climbing and rope work easier and more efficient. It is a versatile tool that works well for arborists, rope access, rescue, and other safety at height jobs. The MultiAscend has a dual cam design, meaning it can be used as a chest ascender or as an attachment point, giving you more options in different situations. The locking swingplate keeps the rope secure, so it doesn't accidentally come loose. The external release triggers make it easy to adjust safely, whether you are using it as an ascender or to hold progress on a safety line. It works with ropes from 9 to 13 mm in diameter, depending on certification standards, and can handle loads up to 140 kg. Made from strong but lightweight materials, the Ninja MultiAscend is comfortable, durable, and reliable for tough environments.
