Anchor loop for arborists with self-release Petzl Naja

Petzl Naja - anchor loop for securing a rope when working in trees with a self-locking rope system after descent.
Designed for professional use, ideal for intensive tree work.
Designed for tree care, the Petzl Naja friction device allows you to install a working rope without damaging the tree.
The strap has four different adjustment positions to adapt to different branch diameters and protects the tree bark from damage.
Rope ascension and movement in the tree are optimised thanks to a high-efficiency pulley that facilitates rope sliding on the anchor.
It comes with a 1.5-metre replaceable bright yellow strap that can be connected to another 1.5 or 2.5-metre strap to extend the friction protection and allow you to work on larger trees.
The system is easy to pull out of the ground, and the soft ball included in the kit makes it easy to remove the entire system from the ground. 
Recommended for use (see the user manual for more details):
- with a double rope (DdRT/MRS);
- with a single rope (SRT/SRS).

Features of Petzl Naja:
- the rope is easy to install and secure in the MINO carabiner for retrieval;
- a built-in high-efficiency block optimises rope sliding on the anchor;
- can be used in two ways for rescue operations;
- 21 mm diameter ball for easy extraction from the ground, designed by Petzl Naja;
- the system can be quickly extracted when the ball is locked in the Petzl Mino carabiner;
- the strap and slots have a thin profile to reduce the risk of snagging in trees;
- Petzl Naja allows the user to work in accordance with ANSI Z133 (USA) standard.
