DMM PerfectO Locksafe Carabiner

Oval carabiners like the PerfectO are designed for load centering, which keeps pulleys, ascenders, and other gear perfectly aligned. Their symmetrical shape prevents equipment from shifting around, making them ideal for technical rigging and aid climbing.

The captive bar keeps the carabiner oriented correctly on your harness or device, preventing it from cross-loading, which can significantly weaken the carabiner. If you don't need that extra security for a specific setup, you can easily remove it to save weight or streamline your gear.

Yes, the PerfectO is specifically engineered for easy one-handed use. Its compact size and smooth Locksafe gate mechanism allow you to open, clip, and lock it quickly without needing to fumble with both hands.

Not at all. The rope bearing areas are fully rounded to minimize friction and wear, which actually helps extend the lifespan of both your rope and the carabiner itself.

Locksafe is DMM's triple-action locking gate. You have to lift, twist, and push to open it, which provides a high level of security against accidental opening while still being manageable to operate when you need to.

The PerfectO is certified to EN12275 and EN362 standards, meaning it meets the requirements for both climbing and industrial safety applications. However, always ensure the 24kN major axis strength is sufficient for the specific loads and safety factors required by your work environment.
