The Locker Draw combines the hyperlight Photon Lock carabiner with the Nimbus Lock HMS carabiner on the rope end for a sophisticated set up that can be used for quick, secure anchors, offset rigging points, and rappel extensions. The Photon Lock is our lightest locking carabiner and the Nimbus Lock has all of the benefits of a full-utility HMS locking carabiner in a compact size. The unique shape ideally positions ropes for smooth action and the SphereLock nose makes clipping ropes and webbing easy. The 12 cm polyamide dogbone features the Karstop Evo carabiner retainer on the rope end to prevent rotation of the carabiner.
