Petzl NAJA Friction Saver

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 due to the high-efficiency pulley which facilitates rope glide at the anchor. The included retrieval ball makes the system easily retrievable from the ground.

Features:

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