K25 ‘CurlyWirly’ Twisted Aluminium karabiner

K25 CurlyWirly Twisted Karabiner

The K25 CurlyWirly karabiner is engineered by At Height UK to provide optimal orientation for rope-descender devices when attaching to a fixed anchor in tensioned line systems. Each K25 karabiner is precision-twisted by 53° to ensure that your descender hangs correctly, reducing torsion and improving overall safety and efficiency during rope-access, rescue, or industrial applications.

    • Gate Opening: 22 mm

  • K25SG (Screwgate):

    • Dimensions: 65 × 107 mm

    • Weight: 83 g

    • MBS: 25 kN

    • Gate Type: Screwgate

    • Gate Opening: 22 mm

• Key Features:

  • 53° Twist: Precisely oriented to guide descender devices into the optimal position, preventing unwanted rotation or cross-loading under load.

  • High Strength & Durability: Rated to a minimum breaking strength of 25 kN, suitable for demanding rope-access and rescue scenarios.

  • Traceability: Each karabiner is individually serialized, allowing for straightforward equipment tracking, inspection, and record-keeping.

  • Lightweight Design: Weighing under 90 g, these karabiners minimize overall system weight without compromising strength.

  • Gate Options:

    • Triple-Action Gate (K25TA) offers enhanced security by requiring three separate actions to unlock, reducing the risk of accidental opening.

    • Screwgate (K25SG) provides a simple, reliable locking mechanism that is quick to operate and inspect.

• Applications:

  • Rope-access and industrial work-at-height operations

  • Rescue and emergency services

  • Tree-care and arborist rigging systems

  • Any tensioned-line setup requiring precise descender alignment

Whether you require the extra safety of a triple-action lock or the simplicity of a screwgate, the K25 CurlyWirly karabiner ensures your descender is always in the correct orientation. Its combination of strength, light weight, and serialised traceability makes it an essential component for professional rigging, rescue, and industrial safety systems.
