Which statement best defines a locking carabiner and its importance in rigging connections?

• A. A carabiner with a locking gate that prevents accidental opening, essential for secure rigging connections.
• B. A non-locking quick-release hook used in stage rigging.
• C. A decorative metal link used for hanging props.
• D. A standard bolt hanger with no gate.

Answer: (A)

A locking carabiner is a carabiner equipped with a gate that can be locked closed, which prevents the gate from opening unintentionally. In rigging, connections must stay secure even under load, vibration, or accidental bumps, so having a locked gate stops the connector from slipping open and releasing the load. This safety feature is why locking carabiners are preferred for critical rigging connections—they help ensure that once clipped, the connection remains secure throughout the performance.

The other descriptions don’t fit because a non-locking quick-release hook lacks a locking mechanism to keep the gate shut; a decorative metal link isn’t designed for safe rigging; and a standard bolt hanger is an anchor point, not a carabiner with a gate.
