PETZL OK Carabiners

• Lightweight Aluminum Construction: Made from durable aluminum, the Petzl OK provides an excellent combination of strength, reliability, low weight, and easy handling for professional rope-work applications.
• Symmetrical Oval Shape: The symmetrical oval profile provides balanced loading and stable positioning of connected equipment, making it especially suitable for devices with a wide cross-section.
• Ideal for Technical Equipment: Designed for connecting and positioning pulleys, rope clamps, ascenders, mobile fall arresters, and progress-capture pulleys.
• Optimized Interior Design: The smooth, fluid interior profile helps reduce potential snagging points and allows the carabiner to rotate smoothly and position itself efficiently.
• Keylock System: The Keylock gate interface minimizes the possibility of the carabiner catching on ropes, webbing, harnesses, equipment loops, or other gear.
• H-Shape Cross-Section: The H-shaped construction provides a comfortable and secure grip, while reducing unnecessary material and helping keep the overall weight low.
• Improved Marking Protection: The H-frame design helps protect the carabiner's markings against abrasion and regular wear during professional use.
• Three Locking Options: Available in SCREW-LOCK, TRIACT-LOCK, and BALL-LOCK versions to meet different operational requirements.
• SCREW-LOCK: Manual locking system offering simple and controlled operation. The red indicator provides a clear visual warning when the carabiner is unlocked.
• Harsh-Environment Performance: The Screw-Lock version is particularly suitable for environments where mud, ice, dust, or contaminants may interfere with automatic locking systems.
• TRIACT-LOCK: Automatic locking system designed for applications requiring frequent manipulation and rapid operation.
• TRIACT-LOCK Opening: Uses a three-step opening sequence: raise the sleeve, turn the sleeve, and press the gate.
• BALL-LOCK: Automatic locking system designed for frequent manipulation and equipped with a visual locking indicator.
• BALL-LOCK Opening: Uses a three-step opening sequence: press the green indicator, turn the sleeve, and press the gate.
• Visual Lock Indicator: Locking indicators provide quick visual confirmation of the carabiner's locking status, helping improve operational safety.
• CAPTIVA Bar Compatibility: Can be connected to the CAPTIVA bar to help keep the carabiner correctly positioned along its major axis.
• Reduced Flipping Risk: The CAPTIVA bar helps limit unwanted carabiner rotation or flipping and maintains better positioning during equipment use.
• Professional Applications: Suitable for rope access, rescue operations, climbing, mountaineering, fall protection, work at height, and technical rope systems.
