Which option describes a carabiner with a screw gate mechanism?

• A. Screw gate carabiners
• B. Auto locking carabiners (twist collar and pull gate)
• C. Supersafe carabiners (push up, twist collar, pull gate)
• D. Industrial clips (snap hooks)

Answer: (A)

The key thing this question tests is how to recognize how the gate is secured on a carabiner. A screw gate carabiner uses a small threaded sleeve around the gate that you twist by hand to close and lock the gate. It requires you to actively screw the gate shut; there’s no automatic locking involved. This distinguishes it from auto-locking types, which lock automatically when you close the gate (often needing you to move a twist collar or perform a pull action). It also differs from more complex self-locking “supersafe” designs that combine push-up, twist, and pull actions, and from industrial clips or snap hooks that aren’t the standard locking carabiner type used for climbing safety. So a carabiner described as having a screw gate mechanism is the one where you manually screw the gate closed to lock it.
