Notch Flow Adjustable Rope Wrench — Custom Friction Bollard for 11–13mm Rope (MBS 5,400 lbs)

Overview

Notch Flow redefines your SRS toolkit with an adjustable concave stainless bollard that lets you tailor friction settings for each ascent. This isn’t a one-size-fits-all wrench; it’s a precision tool that adapts to rope characteristics and climbing conditions, offering a controllable, smoother progression up the line.

Key features

• Adjustable concave stainless bollard provides custom friction settings to match rope feel and climbing needs.
• Robust hot-forged T6 7075 aluminum body with rope-friendly chamfered edges for comfortable handling and long-term durability.
• Designed for quick, efficient integration with Fusion Tether or alternative tethers, and includes a stainless steel slic pin for mid-line rope attachment.

• Ultra-low drag ascent when paired with Fusion Tether, potentially saving time and energy on repeated climbs.
• Rope diameter range of 11 mm to 13 mm (7/16–1/2 inch) with a rated MBS of 5,400 lbs (23 kN), giving you solid performance margins.
• Rugged construction and precise tolerances help maintain consistent friction settings across climbs and setups.

Usage scenarios

Whether you’re practicing technical rope skills, performing multi-pitch transitions, or refining your SRS configuration, Notch Flow aims to provide greater control without sacrificing ease of use. The combination of adjustable friction, a sturdy aluminum frame, and compatible integration options makes it a versatile choice for various ropework tasks. While outcomes will vary with technique and conditions, users may notice a more predictable ascent rhythm and a faster setup when used as part of a cohesive system.

Think of Flow as a tool that supports your existing gear in a modular way. It’s designed to complement Fusion Tether and similar tethers, offering a tangible sense of control during mid-line adjustments and rope management—without locking you into a single workflow. This can help you experiment with friction settings to find what feels most natural for your climbs.
