Petzl Knee Ascent Kit

Petzl Knee Ascent Kit

The Petzl Knee Ascent Kit is a complete rope ascent system built to make SRS (Stationary Rope System) climbing more efficient and comfortable. Designed for integration with the Petzl SEQUOIA harness and other tree care sit harnesses, this lightweight kit helps arborists achieve smoother upward movement while reducing effort during rope ascent.

Efficient support for SRS climbing techniques

Developed specifically for stationary rope system climbing, the Knee Ascent Kit improves ascending efficiency by creating a streamlined connection between the climber and the rope system. The high-strength elastic band works in conjunction with the knee ascender to assist upward movement, helping reduce fatigue during repeated ascents. This makes it a practical addition for professional arborists carrying out regular canopy access and positioning work.

Integrated climbing components for reliable performance

The kit includes a PANTIN right-foot rope clamp, adjustable foot loop, elastic band, plastic guide tube, and MINO accessory carabiners. The PANTIN rope clamp is compatible with low-stretch kernmantle ropes between 7 mm and 13 mm in diameter, offering flexibility across a range of climbing systems. A dedicated catch makes rope installation straightforward, while the durable components are built to withstand regular professional use in demanding tree care environments.

Simple adjustment for personalised climbing comfort

Quick installation and straightforward adjustment allow the system to be adapted to individual climber height and preferences. The elastic band can be routed through the harness waistbelt or attached using the supplied accessory loops and screws. The MINO carabiners make setup simple while also allowing the elastic ends to be connected together, helping centre the rope clamp and increase tension for improved climbing efficiency. Individual replacement parts are available, supporting long-term serviceability.
