Figure-8 descender

A classic Figure 8 Descender designed specifically for rock climbing, canyoneering, high-altitude rappelling, fire escape, and rope technique training. Forged from 7075 aerospace-grade high-strength aluminum alloy, it features an ultimate breaking strength of 35kN and weighs only about 145g, offering high strength, lightweight performance, and excellent heat dissipation.

The core mechanism utilizes contact friction generated by the rope winding around the ring body to achieve a controlled and smooth descent. It is intuitive and easy to learn, allowing for sensitive control of descent speed simply by tightening or loosening the braking end of the rope. The inner diameter of the large ring is 52mm, ensuring smooth rope flow and uniform friction. It can be flexibly paired with short webbing tethers or heat-resistant prusik knots as a backup braking system to comprehensively prevent the risk of losing control. Compliant with the authoritative XF494-2023 fire equipment inspection standard, it is available in a variety of highly visible anodized color options.

Key Features

• Aerospace-grade 7075 Aluminum Alloy: A net weight of only about 145g with a powerful breaking strength of up to 35kN, combining excellent heat dissipation with wear-resistant durability.

• Intuitive and Smooth Friction Control: Classic Figure 8 geometry provides uniform and linear rope resistance, with intuitive braking feel that is extremely easy to master.

• 52mm Large Aperture with Smooth Chamfering: The upper hole diameter reaches 52mm, with finely chamfered edges for smooth rope movement without snagging, significantly reducing abrasion on the main rope sheath.

• Flexible Dual-Protection System: Can be used with short webbing extensions or connected to heat-resistant prusik knots for a secondary locking system, making high-altitude operations more reliable.

• Authoritative Safety Certification: Passed the XF494-2023 fire equipment fall protection standard inspection, ensuring guaranteed safety performance.

• Multi-color High-Visibility Anodized Coating: Available in 7 colors—red, black, orange, blue, gold, gray, and silver—for easy personal identification and team equipment management.
