Locking Carabiners
Locking carabiners are climbing connectors with a gate designed to close and lock, helping reduce the chance of the gate opening unintentionally during use. Compare the locking mechanism and the carabiner’s intended role in your setup. This category includes auto-locking carabiners and screwgate carabiners, which differ in how their gates are secured. Check each listing’s specifications, instructions, and compatibility before choosing.
Choosing a locking mechanism
Locking carabiners share a gate that can be secured against opening, but the mechanism affects how you operate and check the connector. Auto-locking models are designed to lock through their gate mechanism, while screwgate models use a threaded sleeve that the user turns to secure or release. The specific operation varies by model, so read the product instructions rather than assuming every carabiner works the same way.
Consider which mechanism suits the task and your ability to confirm that the gate is closed and locked. Also check how the connector is intended to be used in your climbing system. Gate opening, shape, and other specifications can vary; rely on the details for the individual listing and the equipment manufacturer’s guidance.
Check fit and product details
Before selecting a carabiner, compare its stated dimensions, strength ratings, gate design, and intended use with the requirements of your setup. Confirm that it is compatible with the other equipment it will connect to, and review any instructions or limitations provided by the manufacturer. Do not assume that a locking gate alone makes a connector suitable for every climbing application.
Climbing equipment is safety-critical. Check the product’s actual markings and documentation, including any applicable certification information, and make sure you understand how to inspect, operate, and maintain it. Follow the equipment manufacturer’s instructions and replace or retire gear according to their guidance.

Pay attention to how a connector sits in the setup: its orientation and loading direction can affect how it is intended to function. Follow the manufacturer’s guidance for positioning, and avoid arrangements that press the gate or locking sleeve against other equipment or allow the connector to become improperly loaded.
