Carabiners are connectors specifically designed for use in personal fall protection systems. They comply with EN 362, the European standard defining the requirements for strength, safety and reliability of connectors used in fall protection equipment. Many models are equipped with automatic or screw-locking systems to prevent accidental opening. Carabiners are available in different shapes, materials and locking mechanisms depending on the application. Lightweight aluminium carabiners are often preferred for mobility and comfort, while steel versions offer increased wear resistance in demanding industrial environments.
