Product information & specifications
Rock Exotica rockO Auto-Lock Carabiner (C3A)
The Rock Exotica rockO Auto-Lock (C3A) is a refined, high-performance carabiner that blends the familiar oval shape with Rock Exotica’s rockD profile to deliver increased strength, better gear alignment and more usable space at the basket. Its “enhanced oval” design keeps connectors, pulleys and lines centred in the middle of the bend radius, helping reduce unwanted cross-loading and improving system efficiency.
Featuring a 3-stage auto-locking gate with a pull-down and twist action, the rockO is designed around a motion that feels intuitive and natural in the hand—especially when operating with gloves. The gate sleeve has bevelled internal edges to reduce snag points and minimise the risk of ropes and lanyards hanging up on the gate or sleeve, further reducing the chance of dangerous cross-loading.
A flattened frame and slim profile keep the carabiner compact while preserving a generous, ergonomic gate opening for easy clipping and unclipping. Combined with a snag-resistant keylock nose and CNC-machined frame for tight tolerances and smooth operation, the rockO Auto-Lock is an ideal choice for professional rope access, arboriculture and technical rigging systems.

FAQs
What makes the rockO different from a standard oval carabiner?
The rockO blends an oval and Rock Exotica’s rockD profile to increase strength and provide more room at the bottom of the carabiner, while still centring gear and lines effectively.
How does the 3-stage Auto-Lock work?
The gate uses a pull-down and twist motion before opening, providing secure 3-stage locking that feels natural in the hand and is easier to operate than lift-and-twist designs.
Why are bevelled gate sleeve edges important?
Bevelled edges reduce snag points where ropes or lanyards could catch on the sleeve, helping to minimise cross-loading and providing a smoother interior surface for connected gear.
Is the rockO suitable for arborist and rope access systems?
Yes. Its enhanced oval shape, smooth interior and auto-locking gate make it ideal for applications where gear needs to stay centred and securely aligned, such as pulley setups and lanyard connections.
Does the rockO have a keylock nose?
Yes. The snag-resistant keylock nose helps prevent the carabiner from catching on ropes, slings or hardware when clipping or unclipping.
