Courant Atoll Large Ring - 70mm

Courant Atoll Large Ring – 70 mm

The Courant Atoll Large Ring – 70 mm is a robust aluminium attachment ring designed to be mounted directly onto the bridge of the Koala harness. Developed to support professional arborist climbing systems, it provides a reliable and streamlined connection point that helps improve organisation, efficiency, and freedom of movement while working in the tree.

Aerospace-grade aluminium for strength and reliability

The Atoll ring is manufactured from aerospace-grade aluminium, offering an excellent balance between strength and weight for daily professional use. With a static resistance of 25 kN, the ring delivers dependable performance when used as part of a climbing system. Each ring is individually marked, supporting traceability and ongoing equipment management in professional work environments.

Optimised dimensions for climbing system attachment

Featuring a 70 mm external diameter and a 45 mm internal diameter, the Atoll Large Ring provides ample space for the smooth attachment of climbing systems and connectors. This sizing supports clean alignment of equipment on the harness bridge, helping reduce crowding and allowing systems to sit naturally under load. The generous internal opening supports easy connection and movement during ascent, positioning, and work tasks.

Designed for integration with the Koala harness

The Atoll Large Ring is specifically intended for mounting on the bridge of the Koala harness, where it facilitates straightforward attachment of climbing systems. Its smooth profile supports consistent movement and helps minimise interference with other components on the harness. Weighing 53 g, the ring adds minimal bulk while delivering a solid, stable attachment point suited to professional arborist workflows.
