DMM Revolver Locking Carabiner

The integrated pulley wheel significantly reduces friction by allowing the rope to roll over the carabiner rather than sliding against it. This is particularly useful for reducing rope drag on wandering routes or when setting up hauling and mechanical advantage systems.

Yes, it is designed for on-the-wall protection, but it is best used strategically. Because it is slightly heavier than a standard carabiner, most climbers use it specifically on the crux or the most difficult clip of a route to minimize drag, rather than using it for every draw on their rack.

Not at all. Despite the moving part, the Revolver maintains a robust 24 kN major axis strength. The I-beam construction ensures it remains strong and durable enough for demanding climbing and rescue scenarios.

No, the Revolver features a keylock nose profile. This snag-free design ensures smooth clipping and unclipping, preventing the carabiner from catching on your harness gear loops, slings, or the rope itself.

While it is certified for use in belaying, the Revolver is primarily designed for reducing friction in specific rope-drag scenarios. For standard belaying, a dedicated belay carabiner with a larger gate opening is often more ergonomic and easier to manage.
