The asymmetric D-shaped aluminum carabiner is particularly suitable for connection
various devices, such as abseil brakes, or to the ends of connecting devices.
Thanks to the new 3D shape (H-shaped cross-section), its weight has been reduced while maintaining the same strength.
Its smooth internal shape and KeyLock lock system facilitate handling.
The carabiner is manufactured with four lock safety systems:

• SCREW-LOCK - screw-type for contaminated environments
• BALL-LOCK - automatic for frequent use with practical automatic locking;
  safe use with triple unlocking system
• TRIACT-LOCK - automatic for connecting working equipment with safe locking
  against opening during work
• TWIST-LOCK - automatic for specific use with the need for quick opening;
  sports connection GRIGRI; work end fasteners
