Petzl NAJA adjustable anchoring system for trees

Detailed product description

Anchoring strap, cambium protector for arboriculture, with integrated pulley and strap with different diameter adjustment positions, which can be easily pulled off the ground. NAJA allows installation of the working rope without damaging the tree. The strap has four different adjustment positions to accommodate branches of different diameters. Rope ascent and movement in the tree canopy are optimised thanks to a highly efficient pulley that facilitates the passage of the rope through the anchor point. The included retractable ball allows for easy removal of the system from the ground.

The adjustable cambium protector allows installation of the working rope without damaging the tree:

• The strap has four different adjustment positions to accommodate branches of different diameters
• Special design helps protect the tree
• Supplied with an interchangeable, highly visible 1.5 m strap that can be extended by connecting it to another 1.5 or 2.5 m strap for larger diameters
• Easy installation of the rope with the MINO carabiner supplied separately as an accessory
• Recommended for double rope techniques (DRT/MRS); the system can also be used on single rope techniques (SRT/SRS) (see instructions for more information)

Optimal efficiency:

• Integrated high-efficiency pulley optimises the rope passage through the anchor point
• In rescue, use by two persons is possible

The system can be easily pulled off the ground:

• Black 21 mm diameter ball, specially designed for this NAJA cambium protector
• Once the rope passes through the pulley, the ball stops on the MINO auxiliary carabiner and the system can be pulled down to the ground
• The strap and slots are flat to reduce the risk of the cambium protector getting stuck in the tree crown
• The NAJA cambium protector allows operation in accordance with ANSI Z133
