NAJA

Friction saver for tree care that is easily retrievable from the ground, with an integrated pulley and a strap with different adjustment positions 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.

NAJA Adjustable Friction Saver for Tree Care

Designed to protect trees during rope work, the NAJA adjustable friction saver offers flexibility and efficiency, making it ideal for arborists who need to adapt to various tree sizes without causing damage.

Adjustability and Tree Protection

• Adjustable Strap: Features four different adjustment positions to accommodate various branch diameters, enhancing versatility.
• Tree-Friendly Design: Constructed to minimize impact on the tree, preserving bark and limb integrity.
• Extendable Length: Includes a 1.5 m high-visibility yellow strap that can be connected to additional straps (1.5 or 2.5 m) to extend the friction saver for larger tree work.
• Easy Installation: Simplifies the process of installing the rope and clipping it into the MINO accessory carabiner for efficient retrieval.
• Rope Compatibility: Suitable for use on doubled rope (DdRT/MRS) and can also be used on a single rope (SRT/SRS), with detailed usage instructions provided in the user manual.

Efficiency and Rescue Capability

• High-Efficiency Pulley: Integrates a high-efficiency pulley that optimizes rope glide at the anchor, improving operational smoothness.
• Rescue Support: The system supports two-person usage, making it possible to carry out rescue operations efficiently.

Easy Retrieval and Compliance

• Ground Retrieval: Features a 21 mm black retrieval ball specifically designed for the NAJA friction saver, facilitating easy retrieval from the ground.
• System Retrieval Mechanism: Once the rope passes through the pulley, the system can be retrieved by blocking the retrieval ball in the MINO accessory carabiner.
• Slim Design: The strap and slots are slim to reduce the risk of the friction saver getting stuck in the tree.
• Compliance with Standards: Allows the user to work in compliance with the ANSI Z133 safety standards for arboricultural operations.
