3. Product Features
D-Shape Design
The classic D-shape design directs the majority of the load towards the carabiner's spine, which is its strongest axis. This shape is particularly effective for connecting to equipment such as belay systems, pulleys, descenders, or lanyards, offering efficient handling and a secure grip, even when wearing gloves.

Screw Lock Mechanism
The screw lock system provides a secure closure. It is designed for easy operation: simply turn the knurled barrel to lock the gate, and turn it in the opposite direction to unlock and open the gate. The keylock nose design prevents snagging on ropes or gear.

4. Setup
- Unpacking: Carefully remove the carabiner from its packaging.
- Initial Inspection: Before first use, perform a thorough visual and tactile inspection. Check for any manufacturing defects, sharp edges, cracks, or unusual play in the gate mechanism. Ensure the screw lock turns smoothly and fully engages.
- Familiarization: Practice opening and closing the screw lock several times to become familiar with its operation. Ensure it locks securely with minimal effort.
5. Operating Instructions
5.1. Opening and Closing the Screw Lock
- To Unlock: Hold the carabiner body firmly. Rotate the knurled screw barrel counter-clockwise until it is fully retracted from the gate opening. The gate can now be opened.
- To Open Gate: Once unlocked, push the gate inwards to open the carabiner.
- To Close Gate: Release the gate, allowing it to spring back into its closed position.
- To Lock: With the gate closed, rotate the knurled screw barrel clockwise until it is fully tightened against the gate. Ensure there is no gap and the gate is securely locked. Always double-check the lock before relying on the carabiner.
5.2. Attaching to Equipment
- Select Attachment Point: Choose a secure and appropriate attachment point on your harness, rope, or other equipment.
- Open Carabiner: Unlock and open the carabiner gate.
- Connect: Pass the carabiner through the attachment point.
- Close and Lock: Ensure the gate closes completely and then securely lock the screw mechanism. Verify the lock is fully engaged.

6. Maintenance
- Cleaning: Clean the carabiner with fresh water and a mild soap solution. Rinse thoroughly and dry completely. Avoid harsh chemicals or solvents.
- Lubrication: Occasionally, a small amount of silicone-based lubricant can be applied to the gate hinge and screw mechanism to ensure smooth operation. Wipe off any excess.
- Storage: Store the carabiner in a cool, dry place, away from direct sunlight, chemicals, and extreme temperatures. Avoid storing it with sharp objects that could cause damage.
- Regular Inspection: Beyond pre-use checks, conduct a more detailed inspection periodically. Look for wear on the rope-bearing surfaces, gate function, screw lock integrity, and any signs of cracks or deformation.
7. Troubleshooting
- Stiff Screw Lock: If the screw lock becomes stiff or difficult to turn, clean it thoroughly to remove dirt or debris. Apply a small amount of lubricant as described in the Maintenance section. If stiffness persists, consider retiring the carabiner.
- Gate Not Closing Fully: If the gate does not close completely or springs back slowly, inspect the hinge for debris or damage. Clean and lubricate. If the issue persists, the carabiner should be retired.
- Visible Damage: Any visible cracks, deep gouges, deformation, or signs of excessive wear on the carabiner body or gate warrant immediate retirement.
