Screw Carabiners

A screw lock carabiner is a type of carabiner that features a threaded sleeve mechanism for securing the gate. This mechanism prioritizes security and control over speed of use.

Here’s a breakdown of its key features:

• Threaded Sleeve: The screw lock carabiner has a screw mechanism on its spine. By rotating this sleeve, you can tighten it to lock the gate firmly shut, preventing accidental opening.
• Manual Locking: Unlike some locking carabiners, screw lock varieties require manual operation of the screw for both locking and unlocking. This offers a higher degree of user control over the gate’s state.
• Durability and Reliability: With fewer moving parts compared to spring-loaded mechanisms, screw lock carabiners are generally less prone to malfunction due to dirt, wear, or freezing.

Screw lock carabiners are a popular choice for various activities where a secure connection is crucial, such as:

• Climbing and Rappelling: They provide a reliable locking mechanism for ropes and slings.
• Rigging and Rescue: The secure closure makes them suitable for critical load-bearing situations.
• Work Positioning: They offer a dependable connection point for lanyards and harnesses.

While offering excellent security, screw lock carabiners may be slower to operate compared to twist-lock mechanisms. However, the trade-off in speed is often outweighed by the benefit of increased control and reliability.
