The Gibbs Klimair swiveling ascender is primarily used for 2-in-1 work positioning lanyards. It may also be useful in specific ascending and rigging applications. A simple but secure pin assembly system means you can quickly attach the system to a 1/2″ rope. The bi-directional mechanical prusik has a swiveling stainless steel eye and an aluminum shell, and turns your double-snap flipline into a two-in-one. The Gibbs ascenders are known for being able to grip on any rope whether its muddy, wet, or frozen, while not destroying your expensive ropes
