The Petzl Twist Lock D-shaped carabiner is an incredibly versatile, lightweight, and compact piece of climbing gear. This carabiner is perfect for a wide range of situations. It's easy to handle, even when you're wearing gloves, and comes in three different locking system options.
The D shape of this carabiner is highly functional no matter how it's oriented. You can use it to attach a belay system, a pulley, or at the end of a lanyard. It's both compact and very light, making it a great addition to your climbing kit.
In terms of handling and ergonomics, the D shape offers excellent control. The H-shaped cross-section gives you a better grip when wearing gloves. The Keylock system prevents any accidental snagging. There's also a hole that lets you connect a TIBLOC or a MICRO TRAXION to the carabiner with a cord, so you won't lose these important devices.
You can choose from three locking systems, each designed for different scenarios:
- SCREW-LOCK: An easy-to-open system that can be locked or unlocked according to your needs. The red band shows when the carabiner is unlocked. This system is ideal for tough environments where dirt, mud, or ice could jam an automatic locking system.
- TWIST-LOCK: Great for situations where quick opening is crucial, like at the end of a lanyard or when connecting a GRIGRI to your harness.
- TRIACT-LOCK: An automatic locking system with a triple-action gate opening.

Using the Petzl Twist Lock Carabiner is quite simple. First, make sure to select the right locking system for your needs. If you're in a tough environment, the SCREW-LOCK system is a good choice. Just turn the screw to lock or unlock it, and keep an eye on the red band to know if it's unlocked. For quick openings, go for the TWIST-LOCK system. Just give it a twist to open.
When attaching the carabiner, use it in the D shape's functional orientation. You can attach a belay system, a pulley, or put it at the end of a lanyard. If you want to connect a TIBLOC or a MICRO TRAXION, use the hole on the carabiner and a cord.
As for maintenance, after each use, check the carabiner for any signs of damage, like cracks or excessive wear. Clean it gently with a mild soap and water if it gets dirty. Store it in a dry place to prevent rusting. And always follow the safety guidelines and don't use it beyond its specified strength limits.
