The DMM REVOLVER RIG DUROLOCK TWIN carabiner with pulley is a professional connector with an integrated double pulley designed for work at height, rescue and arborist applications. It combines a full-strength carabiner with highly efficient sheaves mounted on roller bearings, significantly reducing friction in rope systems.

The large sheave diameter ensures a favorable rope bend radius and high efficiency under load. The Revolver Rig design minimizes friction between the rope and the attached connector at the becket, increasing overall system efficiency.

The integrated full-strength becket allows direct textile connection or attachment of most standard connectors. The removable captive bar helps maintain correct carabiner orientation within the system.

The uniquely profiled spine together with the captive bar ensures stable and predictable loading. The keylock nose prevents snagging on rope or equipment and allows smooth handling.

The carabiner is equipped with a DUROLOCK auto-locking gate that requires four distinct actions to open. If force is not maintained throughout the opening process, the gate automatically returns to the safe locked position.
