Nite Ize KnotBone Adjustable Elastic Cord — Grey

The Nite Ize KnotBone is a bungee cord with an adjustable length of 15 to 66 cm and a diameter of 5 mm, designed for anyone who needs to secure loads quickly and reliably without constantly unhooking and rehooking. What sets it apart from standard bungee cords is its carabiner-style terminals with locking grooves, which let you adjust tension simply by pulling the cord and engaging it at the desired position.

The weak point of a classic bungee cord is the open hook: it can release accidentally under vibration or in awkward positions, and the free end becomes a hazard during use. The KnotBone addresses both issues with carabiners that close and retain the wrapped cord, eliminating loose ends. Each terminal also includes a small clip that anchors the excess cord once the length is set, keeping the system from working loose in transit.

Length adjustment is stepless and requires no knots or tools: pull, lock, go. That said, the trade-off is worth noting — the speed of adjustment is the main advantage, but holding strength depends on correctly completing the locking wrap around the carabiner. Anyone who skips the procedure shown in the instructions will get less retention than a pre-tensioned bungee with a fixed hook. The unit weighs 41 grams.
