From the Manufacturer

The unique shape of the Core Lock HMS carabiner creates a very wide gate opening and positions ropes for the smoothest belays and rappels. The inner gate creates a captive eye to prevent rotations that can lead to cross-loading and the SphereLock nose makes clipping ropes and webbing easy.
