EDELRID Ohm II Assisted-Braking Resistor – Oasis/Night, One Size | Belay Device for Sport & Trad Climbing

Overview

When partners vary in weight, belaying with confidence comes from controlled friction and smooth rope work. The Edelrid Ohm II combines a compact, assisted-braking mechanism with a swivel that accepts any clipping direction, making setup intuitive from first clip to last catch.

Designed for sport and trad climbs, the Ohm II balances friction to help you maintain a natural belay flow while keeping rope handling straightforward. The secure locking system adds peace of mind by preventing accidental opening, and the steel/aluminum construction promises durability through seasons of use. Loading and cleaning are easier, so you can focus on the climb itself.

Key benefits

• Swivel joint enables clipping from any angle, reducing awkward rope routing.
• Secure locking system helps prevent accidental opening during intense moments on route.
• Easy loading and cleaning supported by thoughtful design and durable materials.
• Rope compatibility covers common sport and trad diameters (8.9–11 mm).

Real-world use and suitability

On multi-pitch days or dynamic cruxes, the Ohm II can contribute to a smoother belay flow without adding complexity to rope work. It’s especially helpful when belaying partners who weigh more, or when pro moves require quick, confident handling from the belay station.

Climbers appreciate its load-friendly design that remains intuitive when clipping, loading, or re-racking between pitches. The device loads easily onto the rope, cleans with minimal effort, and resists catching grit that can hinder rope movement on dirty rocks.
