It works alongside a foot ascender to capture upward progress with each step, making ascent smoother and less physically demanding.

It is sold separately in Small (up to EU 43), Medium (EU 41-44) and Large (EU 45-46) to match your footwear size.\u003c\/p\u003e\n\n\u003ch3\u003eIs the ASCENTRA PPE?\u003c\/h3\u003e\n\u003cp\u003eNo. The ASCENTRA is a climbing aid for progression assistance only and must never be used for life safety, fall arrest or any purpose other than its intended function within a correctly configured SRS system.\u003c\/p\u003e\n\n\u003ch3\u003eWhat is the maximum load for the ASCENTRA?\u003c\/h3\u003e\n\u003cp\u003e120kg.

A pre-assembled configuration cannot suit every user. STEIN strongly recommends professional instruction from a fully qualified trainer before assembling and using the system.\u003c\/p\u003e\n\n\u003ch3\u003eWhat is the difference between the ASCENTRA and the original STEIN Knee Ascent System?\u003c\/h3\u003e\n\u003cp\u003eThe ASCENTRA uses an updated ascender, a new 4mm HMPE lower sling with a 24-strand cover, and colour-coded STEIN CONNEXT karabiners (Blue and Gold) replacing the original matched karabiners. It is specifically designed for SRS with an explicit 120kg maximum load rating.
