The Petzl Micro Swivel is a compact openable swivel designed for attachment to a locking carabiner and to avoid twisting of lanyards and to allow correct positioning of devices. The bearing-free design allows it to turn freely when not loaded and to stop moving when loaded in order to maintain the devices in position. The compact, openable assembly reduces bulk and weight and has a wide opening for easy, semi-permanent installation on a lanyard or device.
