Petzl KNEE GRAB Knee Ascender – SRS Ascent, SEQUOIA PLUS Compatible (B022BA00)

The Petzl B022BA00 KNEE GRAB is a knee ascender designed for ascending using SRS (Stationary Rope System) techniques. Composed of a PANTIN rope clamp (right) and a webbing strap with adjustable foot loop, it is purpose-designed for use with the SEQUOIA PLUS integrated SRS mounting system — and compatible with other tree care sit harnesses that have a compatible mounting system. Quick setup via MINO accessory carabiners, adjustable to your height, and the PANTIN catch makes rope installation easy. The textile foot loop is available as a spare part (B022CA00). Note: The KNEE GRAB (B022BA00) is the knee ascender only — it does not include the waistbelt tube or elastic band. For a complete SRS ascent kit including the PANTIN clamp, tube, elastic band, foot loop, and MINO carabiners, see the Petzl KNEE ASCENT KIT (B022AA00). For the mounting system only, see the KNEE ASCENT Mounting Kit (B022EA00).

KNEE GRAB (B022BA00) — this product: PANTIN clamp + foot loop only. Use when your harness already has an integrated or separately installed mounting system (tube + elastic band). Designed for the SEQUOIA PLUS integrated SRS system. KNEE ASCENT KIT (B022AA00): Complete kit including PANTIN clamp, elastic band, tube, foot loop, and MINO carabiners. Use when your harness does not have an integrated SRS mounting system (e.g. standard SEQUOIA C069ABxx). KNEE ASCENT Mounting Kit (B022EA00): Tube + elastic band + clip screws only. Use to add or replace the mounting system on a harness without integrated textile loops. Quick Decision Guide Using a SEQUOIA PLUS? — The SEQUOIA PLUS has an integrated SRS mounting system; the KNEE GRAB (B022BA00) connects directly to it Using a standard SEQUOIA (C069ABxx)? — You need the full KNEE ASCENT KIT (B022AA00) which includes the tube and elastic band Already have the tube and elastic band installed? — The KNEE GRAB is the clamp + foot loop component you need Need to replace just the foot loop? — Order the B022CA00 textile foot loop spare part Using 7–13 mm low stretch kernmantle rope? — Yes, the KNEE GRAB is compatible with this rope range Frequently Asked Questions What is the difference between the KNEE GRAB and the KNEE ASCENT KIT? The KNEE GRAB (B022BA00) is the knee ascender component only — PANTIN clamp and foot loop. It is designed for harnesses that already have an integrated or installed mounting system (tube and elastic band), such as the SEQUOIA PLUS. The KNEE ASCENT KIT (B022AA00) is a complete kit that includes the tube, elastic band, and MINO carabiners in addition to the clamp and foot loop — for harnesses without an integrated SRS system. Is the KNEE GRAB compatible with the standard SEQUOIA (C069ABxx)? Yes, but you will also need the mounting system (tube and elastic band). The KNEE ASCENT KIT (B022AA00) includes everything needed for the standard SEQUOIA. Alternatively, pair the KNEE GRAB with the KNEE ASCENT Mounting Kit (B022EA00). What rope does the KNEE GRAB work with? The KNEE GRAB is compatible with low stretch kernmantle rope in diameters from 7 mm to 13 mm. Can I connect the foot loop to my shoe? Yes — in addition to the standard foot loop configuration, the strap can be connected to the top of the shoe via an accessory carabiner such as the MINO (not included). Is the foot loop replaceable? Yes — the textile foot loop is available as a spare part under reference B022CA00.
