FAQ

Q: What is the maximum load capacity of this figure 8 descender?

A: While specific load ratings can vary by manufacturer and testing, aluminum alloy figure 8 descenders are typically designed for loads up to 25 kN (approximately 5600 lbs), suitable for single-person rappels and belaying.

Q: Can this descender be used with dynamic or static ropes?

A: This figure 8 descender is designed to work effectively with both static and dynamic climbing ropes. It provides consistent friction for controlled descents regardless of rope type.

Q: How do I properly install a rope on a figure 8 descender?

A: To install, pass the rope through both large slots, then around the eyelet, and finally back through the large slots. Ensure the rope exits the descender in a way that creates the correct friction angle for your intended use (e.g., rappelling or belaying).
