Ascenders

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.

The Lockjack can totally replace the friction hitches used on climbing lines. The Lockjack works as both an ascender and as a descender for self-belay in the doubled rope technique (DRT). The advantage of the Lockjack is that friction is applied to the rope with a smooth aluminum surface which causes less friction while climbing for an effortless advance, and a smoother more easily controlled descent.

Works with 7/16” or 1/2” rope with a simple part change of the clutch (both clutch sizes are included.) Use with a small D or Oval carabiner only. A larger carabiner may allow the wooden ball to pass through and become stuck, resulting in free fall.

Limited edition of the  Notch Rope Runner Pro that is the ultimate SRT mechanical device. 

This single rope mechanical device makes SRT ascending easier, allowing ascent and descent on a single line without bending the rope. It also allows users to use a foot ascender with this 100% mechanical device.

FEATURES:

• Incredibly easy SRT or DRT climbing
• Unparalleled smooth one-hand descent
• Fully mid-line attachable (stays in one piece!)
• Rope friendly edges
• Flattened 'bird' sections for comfort when descending
• Multiple friction settings
• Integrated central tending point for attachment to a chest harness
• Improved sealed ball bearing pulley
• Internal spring keeps it safe from dirt and debris
• Slic pins keep all of the parts together when the device is opened

The ZIGZAG PLUS mechanical Prusik allows the user to move around efficiently in a tree using classic Prusik pulley system technique. The friction chain provides precision and fluidity when moving around. The pulley is mounted on sealed ball bearings to allow the slack to be taken up easily.

Can be used on either doubled ropes or a single rope, providing great versatility. The lower attachment hole with high-efficiency swivel ensures stable and correct positioning of the mechanical Prusik and optimal rope glide through the device.
