Petzl SECUR Shoulder Straps for Positioning CROLL Ascender - Black

Overview

The Petzl SECUR shoulder straps are a lightweight accessory designed to position the CROLL chest rope clamp on compatible harnesses, including AVAO SIT, FALCON, FALCON ASCENT, and SEQUOIA SRT. By supporting upright alignment and stable tension, they help keep the system neat during ascent.

Key benefits

• Stable positioning: The X-shaped dorsal construction helps prevent the straps from slipping off the shoulders, keeping the CROLL ascender upright and tensioned.
• Dual adjustment: Front and rear DoubleBack buckles allow precise length control to fit a wide range of torso sizes and clothing layers.
• Efficient ascent: When the ventral ascender stays flat and properly tensioned, slack is minimized, supporting smoother upward strokes.
• Lightweight comfort: At only 135 g, you gain chest-harness-like stability without added bulk, which can be beneficial for longer cave explorations.
• Clear scope: This is a positioning accessory, not a life-safety harness, and does not provide fall protection.

Design details and compatibility

Construction focuses on stability and adjustability, with two DoubleBack buckles offering quick but secure changes. It attaches to PETZL harnesses that support the CROLL system to streamline setup in challenging environments.

In the field

Ideal for cavers and climbers who want reliable chest-ascender positioning without extra gear bulk. Use the straps to keep the ventral ascender steady as you advance, especially when traversing uneven terrain or tight passages.

Care and handling: store away from sharp edges and check for wear before each use. Remember, this item is designed for positioning a chest ascender and is not a PPE device.
