Detachable carabiner (class B)
The primary purpose of using Class B detachable carabiners is to connect individual components of fall arrest systems. Using these components eliminates the risk of accidental detachment, while allowing efficient disconnection when necessary. In the offer prepared by PROTEKT you can find a wide range of detachable carabiners.

How to Select the Right Class B Carabiner Lock
A detachable carabiner (class B) is a fundamental connector, but not all locking mechanisms are suitable for every task. The choice between a screw-lock and an auto-lock (like a twist-lock) comes down to a trade-off between speed and security for a specific application.
Screw-Lock vs. Auto-Locking Systems
- Screw-Lock: This manual mechanism is the most basic and secure for "set-it-and-forget-it" applications. Because the user must manually tighten the gate, it's ideal for semi-permanent connections where the carabiner won't be opened and closed frequently. This includes rigging, anchoring a device, or setting up a belay.
- Twist-Lock & Double Twist-Lock: These are auto-locking mechanisms. They are essential for a detachable carabiner that is clipped and unclipped multiple times during a workday. A simple twist-lock (requiring two actions: twist and pull) is fast and efficient. A double twist-lock (requiring three actions: lift, twist, and pull) offers an extra layer of safety, preventing accidental gate opening, and is a common choice for connecting a worker's harness to their primary fall arrest system.
Material and System Compatibility
Your detachable carabiner must be compatible with the entire fall arrest system. Aluminum carabiners are lightweight, reducing the overall weight on a worker's harness and making them ideal for connecting to energy absorbers and lanyards.
In contrast, steel carabiners offer superior durability and strength, making them the perfect choice for heavy-duty rigging or connecting to abrasive components, such as the steel cables found on retractable-type fall arresters. While this page focuses on Class B, you can browse our full range of carabiners for other classes and specific applications.
