The Cypher Iris HMS Single-Stage Auto-Locking Carabiner is a compact, versatile belay carabiner designed for smooth rope handling and reliable performance. Its refined HMS pear-shaped design provides ample space for belay devices and knots while maintaining a lightweight, easy-to-handle frame ideal for rock climbing, trad climbing, and anchor systems.

A rounded rope-bearing surface allows ropes to move smoothly during belays and rappels, improving control and reducing rope wear. Despite its compact size, the Iris features a generous bell shape that works well with a Munter hitch, making it a great option for climbers traveling light or building minimalist belay systems.

The single-stage auto-locking gate automatically locks when the gate closes, providing added security and convenience during belays or anchor setups. Lightweight, durable, and easy to operate, the Cypher Iris HMS Auto-Locking Carabiner is an excellent choice for climbers looking for a dependable locking carabiner for belaying, rappelling, and fast-and-light climbing adventures.
