Kratos 22mm Steel Triple-Lock Karabiner - 40kN Breaking Strength

Kratos 22mm Steel Triple-Lock Karabiner

Where a screw-lock karabiner relies on the operative remembering to re-lock the sleeve after every connection, the triple-action gate on this karabiner locks automatically every time it closes. Three deliberate sequential actions are required to open it, which means it cannot be opened accidentally and cannot be left unlocked through oversight. At 40kN breaking strength, it exceeds the EN362:2004 Class B minimum by a significant margin, making it the higher-specification connector in the range for demanding fall arrest applications. The 22mm gate opening and asymmetric profile allow correct positioning between connected components and accommodate a wider range of lanyard end loops and anchor hardware than the 18mm screw-lock.

Why Choose the 22mm Steel Triple-Lock Karabiner

• Triple-action automatic locking gate: The gate locks automatically every time it closes. Three separate sequential actions are required to open it. This eliminates the risk of an operative forgetting to re-lock the gate after a connection, which is the primary misuse failure mode for screw-lock connectors in high-frequency applications.

• 40kN breaking strength: 60% higher than the 25kN minimum required by EN362:2004 Class B. For buyers specifying connectors for demanding structural connections or high-load anchor applications, this provides a meaningful additional safety margin above the standard minimum.

• 22mm gate opening: Wider than the 18mm screw-lock, accommodating larger lanyard end loops, thicker webbing, and a wider range of anchor hardware without requiring force to connect. Still within the sub-30mm category for connection element use rather than large structural anchoring.

• Asymmetric profile: The D-shaped asymmetric body positions the connected components toward the spine of the karabiner, keeping them away from the gate and ensuring load is applied along the major axis where the breaking strength is rated.

• Steel with zinc electroplating: Correct material choice for construction and industrial environments where abrasion, impact, and corrosive conditions would compromise an aluminium connector over time.

• Suited to frequent-use applications: Where operatives are connecting and disconnecting multiple times per shift, the automatic locking gate removes the manual step required by a screw-lock and reduces the risk of misuse through fatigue or time pressure.

Who Is This For?

This karabiner is for operatives and procurement teams specifying connection hardware for fall arrest and height safety systems where frequent connection and disconnection is required throughout the working day. It is the correct choice over the screw-lock karabiner wherever the operative will be connecting and disconnecting multiple times per shift, including scaffolders transferring between anchor points, steel erectors moving across a structure, and maintenance operatives working across multiple positions in a single session.

Typical Applications

• Harness-to-lanyard connections on projects requiring frequent anchor transfers

• Lanyard-to-anchor connections where the operative repositions multiple times during a shift

• Replacement or spare connector for fall arrest kits on high-frequency use projects

• Connection element in guided type fall arrester systems on rope anchorage lines

• Secondary connection hardware in twin-tail forked lanyard systems

• Any application where a screw-lock karabiner presents a misuse risk through frequency of operation

How to Use

1. Inspect the karabiner before each use. Check for deformation, cracks, corrosion, and correct gate and locking mechanism function. Do not use any karabiner that fails inspection.

2. To open the gate, complete the three sequential actions required by the triple-action mechanism. Do not force the gate.

3. Connect to the intended attachment point. Confirm the connection is along the major axis of the karabiner and toward the spine, not the gate side.

4. Release the gate. Confirm it closes fully and the automatic locking mechanism engages before applying any load.

5. Never load the karabiner across the minor axis or against the gate.

6. After use, inspect before storage. Withdraw from service immediately after any fall arrest event.

Safety

• Always load along the major axis. Cross-loading or gate-loading significantly reduces breaking strength and can cause failure.

• The triple-action gate locks automatically but must be confirmed closed and locked visually before each use.

• Do not use on outside support areas, sharp edges, or surfaces that could damage the gate or body.

• Withdraw from service immediately after any fall arrest event regardless of visible condition.

• Do not use this karabiner as an anchor connector for structural sections exceeding the gate opening.

Maintenance

• Inspect before and after every use for deformation, corrosion, gate damage, and locking mechanism function.

• Clean with a damp cloth. Remove concrete, metal swarf, and chemical contamination before storage.

• Lubricate the gate hinge and locking mechanism periodically with a light oil if the action becomes stiff.

• Store away from corrosive chemicals, salt, and damp environments.

• Formally inspect by a competent person at intervals not exceeding 12 months with written records per PUWER.

• Retire from service if the gate does not close and lock automatically, if the body shows deformation, or if the connector has been involved in a fall arrest event.

Frequently Asked Questions

Q: What is the difference between this karabiner and the 18mm Steel Screw-Lock Karabiner?

 A: There are two key differences. First, the locking mechanism: this karabiner has a triple-action automatic gate that locks every time it closes and requires three sequential actions to open, eliminating the risk of an unlocked gate through oversight. The screw-lock requires manual re-locking after every connection. Second, the breaking strength: this karabiner is rated at 40kN versus 25kN on the screw-lock. For frequent-use applications, this is the correct choice. For occasional or fixed connections, the screw-lock is sufficient.

Q: What does triple-action mean and why does it matter?

 A: Triple-action means the gate requires three separate sequential movements to open: typically a push, a twist, and a pull, or similar combination depending on the specific mechanism. This makes accidental opening virtually impossible under normal working conditions. It also means the operative does not need to remember to re-lock the gate manually after each connection, which is the most common misuse failure with screw-lock connectors. For operatives connecting and disconnecting multiple times per shift, triple-action is the safer choice.

Q: What does 40kN breaking strength mean and how does it compare to the minimum standard?

 A: EN362:2004 Class B requires a minimum breaking strength of 25kN along the major axis. This karabiner is rated at 40kN, which is 60% above the minimum requirement. In practical terms, this means a larger safety margin above the forces generated in a compliant fall arrest event. For buyers specifying connectors for structural anchor connections or demanding industrial applications, the higher rating provides meaningful additional confidence beyond the standard minimum.

Q: What does EN362:2004 Class B mean for this karabiner?

 A: EN362:2004 is the European standard for connectors used in personal fall protection systems. Class B covers general connectors used as connection elements between components within a fall arrest system. CE marking to this standard is the legal confirmation that the karabiner meets the requirements for use in a fall arrest system on a UK site under the Personal Protective Equipment at Work Regulations 1992.

Q: Why is the asymmetric shape better than an oval for most fall arrest applications?

 A: An oval karabiner distributes load evenly across both sides, which suits applications with two contact points such as pulley systems. An asymmetric karabiner positions the connected components toward the spine, which is the strongest part of the body, and away from the gate, which is the weakest. For harness-to-lanyard and lanyard-to-anchor connections, the asymmetric shape ensures load is correctly applied along the major axis, which is where the 40kN breaking strength is rated.

Q: Can this karabiner be used as a scaffold tube anchor?

 A: No. The 22mm gate opening is suited to component-to-component connections within a fall arrest system. For direct anchorage to scaffold tubes, a rebar hook with a 60mm gate opening is the correct product. This karabiner is a connection element, not a structural anchor connector.

Q: What should I do if this karabiner has been involved in a fall arrest event?

 A: Withdraw it from service immediately. Dynamic loading during a fall arrest event can stress the connector beyond what is visible externally. Quarantine it, label it as withdrawn, and have it assessed by a competent person. In practice, any connector involved in a fall arrest event should be scrapped and replaced.
