DMM PerfectO

The PerfectO's symmetric oval shape is designed to center loads perfectly, which prevents the carabiner from shifting or rotating during use. This makes it an ideal choice for use with pulleys, ascenders, or when you need a predictable, stable connection point.

Despite its compact 95mm length, the PerfectO is engineered for easy handling. The gate geometry and snag-free keylock nose are specifically designed to ensure you can clip and unclip smoothly with one hand, even while wearing gloves.

The captive bar creates a semi-permanent connection that keeps the carabiner oriented correctly on your harness or device. It is a critical safety feature that prevents the carabiner from rotating and cross-loading, which would significantly reduce its strength.

Yes, the fully rounded surfaces are much gentler on your ropes and webbing compared to carabiners with sharper edges. By distributing the load more evenly across the rope, you reduce friction and extend the lifespan of your gear.

The PerfectO is certified to both EN12275 (mountaineering) and EN362 (industrial) standards. This dual certification means it is robust enough for professional rope access and rescue applications, as well as recreational climbing.
