Locking carabiners are indispensable tools in the climbing world, serving essential safety functions for both novice climbers and seasoned veterans. These devices prevent the accidental opening of the gate, enhancing the climber's safety significantly, and they are an integral part of all belay setups.
Since its founding in 2010, GearLab has consistently tested and evaluated locking carabiners. Throughout this period, nearly 40 different models have been assessed, leading to the comprehensive review of 15 of today's top choices. These carabiners have been put through their paces in various climbing scenarios—including as part of multi-pitch anchors, personal anchor systems, and while tackling the challenges of big wall climbs like El Cap.
Leading the pack in our rankings is the Petzl Attache, a carabiner celebrated for its strength, lightweight framework, and versatility. “This is the carabiner that I most frequently grab, thanks to its simple and clean design and solid performance,” said our lead tester, indicating its reputed usability and reliability.
For those seeking a budget-friendly option, the CAMP USA Photon Lock stands out. It is a user-friendly, full-sized locking carabiner that does not skimp on quality while remaining accessible to more cost-conscious climbers. “It offers great value without compromising on essential features,” added a product tester during our evaluation.
Our investigations have also highlighted specific applications of other popular models. The Petzl Sm'D Twist-Lock, for instance, is recognized as the best offset-D shaped locker, while the DMM Phantom ranks high as a compact option. According to our findings, the Edelrid HMS Bulletproof Triple FG offers unparalleled durability, making it ideal for climbers who push the limits of their gear.
In belay scenarios, especially for those utilizing a GriGri device, the DMM Rhino is recommended for its reliability and ease of use. Each model has been categorized not only by performance but also by specialized functions suited to various climbing circumstances.

Highlights of the Petzl Attache:
With an overall score of 81, the Petzl Attache is our best overall locking carabiner. Its specifications include: - Weight: 57g - Lock Closure Type: Screw-lock
Pros include its affordability, exceptional functionality, and the largest gate clearance among its peers. The bright red safety stripe offers a visual confirmation that the gate is secured. However, it is worth noting that the screw gate may become stuck, and it is not an auto-locking model. Nevertheless, the Petzl Attache's pear shape allows for versatility in clipping multiple ropes or carabiners without causing overlaps, making it a favorite among climbers.
