Petzl Knee Ascent Foot Loop – Smooth Single‑Rope Ascents for Arborists

The Petzl Knee Ascent Foot Loop makes climbing single ropes easier and more efficient for arborists and rope professionals. It works in tandem with a mechanical Prusik device such as the Petzl ZIGZAG or ZIGZAG PLUS, letting you ascend with better control, comfort, and foot placement.

This assembly includes an upper strap, a CROLL L rope clamp, a lower strap with a built‑in foot loop, and an XS‑size tool pouch for convenient storage. You clip the upper strap into your mechanical Prusik setup and adjust the lower loop to fit your boot. This setup keeps your foot in the optimal position and lets you push up the rope efficiently.

The CROLL L rope clamp gives secure engagement with ropes from 8 mm to 13 mm in diameter, matching most professional arborist ropes and EN 1891 type A low‑stretch lines. The clamp’s integrated thumb catch lets you install or remove it quickly, so you can set up and pack away faster.

Its fully adjustable straps adapt to a wide range of body sizes and climbing styles. You can fine‑tune fit and tension so your ascent feels balanced and efficient from the first step to the top. The included tool pouch keeps the assembly compact and ready to grab when you need it.

Engineered with aluminium, steel, nylon, and polyester components, this foot loop resists daily wear and provides dependable performance season after season. It weighs about 280 g, so it adds minimal bulk to your climbing system while delivering real functional benefit.

Use the Petzl Knee Ascent Foot Loop when you want stronger, smoother progress up a single rope. It enhances foot‑based ascending techniques and integrates easily with mechanical Prusik devices for reliable, ergonomic climbs in tree‑care, rescue, and rope‑access work.
