Petzl Naja Friction Saver

The NAJA friction saver, designed for tree care, allows the work rope to be put up without hurting the tree. The strap includes four adjustment points to accommodate varying branch sizes. The high-efficiency pulley, which facilitates rope glide at the anchor, optimises rope ascents and mobility in the tree. The system is easily retrievable from the ground thanks to the provided retrieval ball.

• Adjustable friction saver allows the work rope to be set up without harming the tree:
  - Strap has four different adjustment positions to adapt to different branch diameters
  - Special design helps protect the tree
  - Comes with 1.5 m replaceable, high-visibility yellow strap that can be connected to another 1.5 or 2.5 m strap to lengthen the friction saver and enable work on larger trees
  - Easy to install the rope and clip it into the MINO accessory carabiner for retrieval
  - Recommended for use on doubled rope (DdRT/MRS); the system may also be used on a single rope (SRT/SRS) (more information in the Instructions for Use) (1)
• Optimal efficiency:
  - The integrated high-efficiency pulley optimizes rope glide at the anchor
  - Two-person use is possible for carrying out a rescue
• System is easily retrievable from the ground:
  - 21 mm black retrieval ball, specially designed for the NAJA friction saver, for easy retrieval from the ground
  - Once the rope has passed through the pulley, the system can be retrieved when the retrieval ball becomes blocked in the MINO accessory carabiner
  - Strap and slots are slim to reduce the risk of getting the friction saver stuck in the tree
