CMC DNA Steel Carabiners

Optimized for Rescue Applications — Built for High-Load Performance

The CMC DNA Steel Carabiner is engineered for professionals operating in high-risk, high-demand environments. With its unique helical body shape, auto-locking gate, and steel construction, it’s designed to deliver reliable performance in rope rescue, technical operations, and first responder applications.

High-Strength Construction & Smart Geometry

• Carbon-steel body rated for 40 kN on the major axis, 16 kN on the minor axis, and 11 kN with the gate open
• Helical shape rotates 90° to keep connected devices properly aligned, reducing cross-loading and improving system efficiency
• Auto-locking gate (lift, turn, push) ensures security while allowing fast operation — even with gloves
• Key-lock nose prevents snagging on rope, webbing, or hardware
• Corrosion-resistant finish provides long-term durability in demanding rescue or fire-service environments

Why It Belongs in Your Rescue Kit

• Rescue-Ready Geometry: The 90° design helps maintain proper alignment under load — critical in complex rigging and rescue systems.
• Steel Durability: Carbon-steel construction delivers exceptional tensile strength and longevity, outperforming aluminum in heavy-duty or repetitive-use scenarios.
• Secure Locking Under Pressure: The three-step auto-lock gate requires intentional movement to open, preventing accidental release during operations.
• Smooth, Snag-Free Design: The key-lock nose and wide gate opening allow quick, reliable clipping and unclipping — even in gear-dense or low-visibility environments.
• Certified Performance: Meets ANSI Z359.12 and NFPA General Use standards for professional rescue equipment.

Ideal for Fire and Rescue Applications

• Anchor systems for rope or high-angle rescue
• Haul and belay setups for confined-space operations
• Litter or stokes basket rigging
• Integration with descent control or progress-capture devices
• Technical rescue and training environments
