Petzl NAJA

Designed for tree care, the NAJA friction saver allows the work rope to be set up without damaging the tree. The strap has four different adjustment positions to adapt to different branch diameters. Rope ascents and movement in the tree are optimized, thanks to the high-efficiency pulley which facilitates rope glide at the anchor. The included retrieval ball makes the system easily retrievable from the ground.

The strap of the NAJA friction saver offers four different adjustment positions to better adapt to different branch diameters. Easy to install the rope with it clipped into the MINO accessory carabiner. The slimness of the strap and slots helps reduce the risk of the friction saver getting stuck in the tree during retrieval. Use with a doubled rope system is preferred, but the system can also be used with a single rope system.

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 strap that can be connected to another 1.5- or 2.5m strap to lengthen the friction saver and enable work on larger trees
• Easy to install the rope with it clipped into the MINO accessory carabiner
• Recommended for use on doubled rope (DRT/MRS); the system may also be used on a single rope (SRT/SRS)

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:
• 21mm 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

The NAJA friction saver allows the user to work in compliance with the ANSI Z133 standard
