STEIN Knee Ascent System

The STEIN Knee Ascent System is a simple but highly effective tree climbing ascent aid designed to help arborists ascend their climbing system more easily and more efficiently. Built to work alongside a foot ascender, this system captures the upward progress created with each step, helping improve climbing rhythm and reduce effort during ascent.

Suitable for use on both Double Rope Technique (DRT) and Single Rope Technique (SRT) climbing systems, the STEIN Knee Ascent System is a practical addition for climbers looking to streamline rope access and make upward movement smoother and faster.

Important Notice: This product is not for use as PPE.

Designed to Improve Climbing Efficiency

The STEIN Knee Ascent System is intended to work in conjunction with a foot ascender such as the STEIN DJANGO. As your foot ascender creates upward movement, the knee ascender helps capture and retain that progression, allowing for a more efficient climbing motion.

This makes it particularly useful for arborists climbing longer ascents or looking to reduce fatigue while working on rope systems.

Compatible with DRT & SRT Climbing Systems

The system can be used with:

• DRT (Double Rope Technique) systems
• SRT (Single Rope Technique) systems

This gives climbers flexibility to integrate it into their preferred climbing method while improving upward progression and rope efficiency.

Important Setup Information

Because every climber’s technique, body size and preferred system setup is different, the STEIN Knee Ascent System is intentionally supplied as a self-assembly kit. This allows users to tailor the setup to suit their own climbing style and system configuration.

In addition to this kit, you will also require a STEIN CAMBO Foot Loop to complete the setup.

Users should seek professional training from a fully qualified and competent instructor before use. If you are not able, or not in a position to assume this responsibility, you should not use this product.

The system should be checked regularly and before every use.
