The pin stays captive inside the shackle body which means it can't be lost. It is also auto-locking, just push it closed until your hear it click. A non-rotating pin gives you freedom to use the shackle in any orientation without worrying about it coming undone. The super narrow head profile ensures a snag-free experience.
It's easy to fit a PureLock in your style of rigging. Whether it be slings, spansets, rope anchors, pulleys or a soft-release. The shackle is built for slacklining with a larger bow than a traditional steel 3¼ ton shackle.
The design is a result of over 2 years of testing and design iterations. We've worked with a local testing facility in Sydney to load test each batch of prototypes, gaining a ton of knowledge along the way, and resulting in many refinements to the design.
The power of CNC machining allows both the shackle bow and the lock insert to be milled from a single block of 7075 grade aluminium. Compared to 304 grade stainless steel, the strength-to-weight ratio is over 3 times higher.
