Lock Jack Sport
This revolutionary ascending and descending system is simple to use. Incoming rope falls easily through the device using the weight of the rope itself to take up slack. Climber can use the Lock Jack as a mechanical prusik and easily advance on the rope. Simply pull down on the wooden knob to release the prusik and decend. Device can be installed mid-line and features a swivel carabiner attachment.
