Rock Exotica RockD Autolock Carabiner – 29 kN, D-Shape

Rock Exotica RockD Autolock – Ergonomic 3-Stage Autolocking D Carabiner

The Rock Exotica RockD Autolock (SKU: KC2A) combines a narrow asymmetric D-shape with an innovative 3-stage autolocking gate mechanism that's more intuitive to operate than traditional lift-and-twist designs. The pull-down and twist action works with your hand's natural motion, while beveled gate edges minimize cross-loading risk — a thoughtful engineering detail that matters when you're 60 feet up.

Key Features

• 3-stage autolock gate — ergonomic pull-down and twist action, more natural than lifting up
• Beveled gate sleeve edges reduce cross-loading risk from ropes and lanyards
• Key-lock nose for snag-free clipping and unclipping
• Narrow asymmetric D-shape optimizes strength while reducing weight
• Large angled gate opening (0.95"/24mm) for easy clipping with gloves
• 80g weight — lightweight for all-day use

Frequently Asked Questions

What makes the 3-stage autolock different from a standard twist-lock?
The pull-down and twist action works with your hand's natural grip motion rather than requiring you to lift the sleeve up and away from your palm. Rock Exotica also engineered beveled edges on the gate sleeve to reduce the risk of ropes or lanyards catching on the gate edges and causing cross-loading.

What is the difference between the RockD Autolock and the RockD Orca?
Both share the same body, dimensions, and MBS ratings. The Autolock uses a 3-stage pull-down and twist mechanism. The Orca uses a push-up and twist mechanism and can be set to remain in the unlocked position — useful when frequent clipping and unclipping is needed. 

Is this carabiner suitable for arborist climbing?
The RockD Autolock is CE certified. Always verify that the certifications meet your employer's requirements and applicable local regulations before use in a professional climbing system.
