The Singing Rock Osma L descender is made from duralumin, a high-performance aluminum alloy that combines lightness and robustness. The design ensures minimal wear and good heat dissipation during prolonged descents.
This device accepts ropes from 8.5 to 13 mm, making it suitable for thicker climbing and canyoning ropes. The wide range of diameters ensures versatile use across different equipment and scenarios.
With a nominal strength of 30 kN, the Singing Rock Osma L offers a significant safety margin for rappel and belaying operations. Its geometry facilitates progressive braking and precise control of descent speed.
The figure eight design optimizes friction and thermal dissipation for a comfortable descent. Its matte black finish and lightweight (125 g) make it easy to carry and integrate into the harness without adding bulk.
