Best Handling Among Ultralight Carabiners - Experience fumble-free clipping pitch after pitch with the widest gate opening (19mm) in the ultralight category, making it easy to clip even with gloves or cold hands on alpine routes Double Bent Wiregate Design - Effortless clipping action from every angle with our innovative double bent wiregate that guides rope naturally into the basket, reducing clipping failures during lead climbs or quickdraw placement Snag-Free Bull Nose Technology - Partially hooded Bull Nose design prevents rope hang-ups during unclipping, keeping you moving efficiently on multi-pitch climbs, sport routes, or when building gear anchors Ultralight Without Compromise - At just 24g (0.85oz), this 20kN-rated carabiner delivers full-strength protection for trad climbing, sport routes, and alpine ascents where every gram matters on your rack Athlete-Driven Engineering - Designed by Trango in Boulder, Colorado with input from professional climbers to create gear that performs flawlessly from gym to crag, trusted by the IFSC for international competitions The Trango Quantum represents the next evolution in ultralight carabiner design, combining best-in-class handling with the weight savings serious climbers demand. Engineered in Boulder, Colorado by our athlete-driven team, this carabiner solves the fundamental challenge every climber faces: how to reduce pack weight without sacrificing performance or safety. At the heart of the Quantum's design is the widest gate opening among ultralight carabiners. That extra millimeter of clearance makes a measurable difference when you're pumped on a sport route, wearing gloves on an alpine climb, or quickly building anchors on a multi-pitch adventure. The double bent wiregate isn't just about weight reduction—it creates an intuitive clipping motion that works from any angle, dramatically reducing clipping failures when you're fatigued or racing the clock.
