The ON Chest Ascender is designed for Single Rope Technique (SRT) operations, used for ascending ropes during climbing, caving, rescue, and high-altitude work.
- Manufactured using CNC machining, its profile is designed for smoother rope travel.
- The multi-radius cam design reduces resistance when pushing the ascender upward and provides a stronger bite when stopping, ensuring stable performance even on wet, icy, or mud-covered ropes.
- The cam features self-cleaning grooves to automatically expel mud and debris.
- An easy-to-operate, double-sided opening trigger facilitates handling.
- The enlarged lower hole allows a carabiner to rotate freely.
