To be honest, the Jake is one of the coolest carabiners on the market and, for years, has set the standard for belay/harness carabiners. Ever since we came out with this design in 1997, it's set the bar pretty high for this type of product. To start with, its shape orients the load predictably where we want it every time. Other belay carabiners can be loaded on the spine, like they were intended, or sometimes, closer to the nose of the 'biner … where they're decidedly weaker.
The Jake eliminated this problem through a superior design, so that it's always loaded along its strongest axis. It also centers your belay/rappel device so that in double rope rappels, neither strand of rope is pinched on the spine, ensuring a smooth and predictable rap'. This won't leave you with uneven lengths of rope at the bottom, due to friction on only one strand. The Jake is also equipped with a truly unique side-swing gate which provides you with greater gate clearance and ease of use. Available with Screwgate, Quik-Lok or the 3-Stage Quik-Lok locking mechanisms.
