What are the differences between Petzl Freino carabiner models?

What is the difference between the Petzl Freino Twist Lock, Petzl Freino Z, and Petzl Freino Z TL?

The main difference between these Petzl Freino carabiners lies in their compatibility with descenders and the type of locking mechanism.

Main Differences (2026)

Model System Main FeatureCompatibility
Freino Twist-LockTwist-Lock (2-step)The "classic" model with the locking pin at the top. Suitable for older and standard descenders
Freino ZTwist-Lock (2-step)The "Z" version is reversed; the locking pin is at the bottom near the opening.Specifically for the STOP and SIMPLE (models from 2019 onwards)
Freino Z TLTriact-Lock (3-step)Same design as the Freino Z, but with a more secure triple locking mechanism.Professional devices such as the I'D (S, L, EVAC) and RIG.

Detailed explanation:

  • Freino Twist-Lock (Classic): This model is designed to add extra friction during descents. The brake pin is located on the side of the carabiner's locking mechanism.
  • Freino Z: The "Z" refers to the new geometry that allows the carabiner to be rotated through the descender's eyelet. This prevents you from losing the device while transferring your gear loop to your harness. This version has a Twist-Lock (twist and open).
  • Freino Z TL (Triact-Lock): This version is technically identical to the Freino Z, but uses the Triact-Lock system (push up, twist, and open). This is often required in professional work environments (e.g., Rope Access) for added security against accidental opening.

Note: The Freino Z models are specifically designed to fit through the connection hole of modern Petzl descenders, which is not possible with the original Freino.
