• SCREW-LOCK System: An easy-to-open locking mechanism ideal for environments where dirt, mud, or ice might interfere with automatic locking systems. A visible red band indicates when the carabiner gate is unlocked, providing a clear safety warning.
• Keylock System: Designed to prevent the carabiner from snagging on ropes, slings, or other gear during operation.
• Keeper Hole: A small hole designed to attach a cord, allowing for secure connection of devices like a TIBLOC or MICRO TRAXION to the carabiner, minimizing the chance of dropping equipment.

Setup and Inspection

Before each use, a thorough inspection of the carabiner is crucial to ensure safety and proper function. Always refer to the detailed instructions provided by Petzl for complete setup and inspection guidelines.

Pre-Use Inspection:

• Visual Check: Inspect the carabiner body for cracks, deformation, sharp edges, or excessive wear.
• Gate Function: Ensure the gate opens smoothly and closes completely and automatically when released.
• Locking Mechanism: For SCREW-LOCK, verify that the screw sleeve rotates freely and fully engages the gate. Confirm the red warning band is visible when unlocked and hidden when locked.
• Rivet and Pin: Check that the gate rivet and any other pins are secure and not damaged.
• Corrosion: Look for any signs of corrosion, especially in the gate mechanism.

Initial Setup:

The Sm'D carabiner is designed for immediate use after inspection. No complex assembly is required. Simply ensure it is clean and free of debris before integrating it into your climbing system.
