Carabiner PETZL Vulcan Triact screw-lock 30 kN strength, 12 mm gate width

Petzl Vulcan Triact screw-lock carabiner is a high-strength connector intended for climbing, rope access and rigging tasks. Engineered with a three-action Triact locking mechanism and a 30 kN major axis strength rating, this carabiner offers a secure attachment point for harnesses, anchors and equipment. The 12 mm gate width accommodates webbing, ropes and multiple connection types while maintaining a compact, robust alloy body suited to repeated field use.

Advantages

The Triact screw-lock mechanism provides an intuitive three-action locking sequence that reduces the risk of accidental opening while allowing controlled manual operation. With a 30 kN major axis strength rating and a durable alloy construction, the carabiner delivers reliable load-bearing performance for overhead loads and protection systems. The 12 mm gate width supports easy clipping of slings and compatible hardware without excessive bulk, and the overall geometry balances strength, usability and weight for professional and recreational applications.

Suitable for

• Connecting harnesses to belay devices and anchors in climbing and mountaineering
• Industrial rope access, work positioning and rescue systems
• Rigging and temporary anchor configurations
• Securing equipment, tool lanyards and accessories in vertical work

When it may not be suitable

This carabiner is designed for load-bearing climbing and work-at-height applications; it is not intended for use where certification for specialized non-climbing uses is required (for example specific marine or aerospace approvals). It should not be used if reduced clearance or an atypically narrow gate width is required for particular hardware or tight-chain link connections.

Key specifications

• Major axis strength: 30 kN
• Gate type: Screw-lock (Triact) three-action locking
• Gate opening width: 12 mm
• Material: High-strength alloy body and gate
• Typical use: Climbing, rope access, rigging

How to use

Before each use, inspect the carabiner for visible damage, deformation, excessive wear or corrosion, and ensure the screw-lock operates smoothly. To attach, open the gate, clip the rope, sling or anchor point into the carabiner body, release the gate and fully screw down the Triact sleeve until the three-action lock engages. Confirm the gate is correctly closed and locked before loading. When unfastening, reverse the sequence: unscrew the sleeve, open the gate and remove the connector. Follow relevant safety standards and procedures for clipping, belaying and securing loads.

What to consider before purchase

• Verify compatibility with your harness, anchors, slings and other hardware in terms of gate width and geometry
• Check that a screw-lock Triact mechanism meets your operational needs versus other locking types (auto-locking, twist-lock)
• Ensure the carabiner’s strength rating and material suits your intended climbing or work-at-height applications

Usage recommendations

Use the Petzl Vulcan Triact carabiner only with certified personal protective equipment and within manufacturer recommendations. Regularly inspect and retire the carabiner if deformation, cracks, excessive wear or compromised locking function are found. Store in a dry, cool environment away from chemicals and avoid heavy drops or impacts that could reduce strength.
