Parameters of carabiners

Twist Lock (2T):

The twist lock system has an automatic lock and quick unlock. To open the carabiner, do two independent movements as shown in the picture.

Tri-Lock (3T):

The Tri-Lock system has an automatic lock and quick unlock. To open the carabiner, three independent movements are needed as shown in the picture.

Keylock: 

Keylock is a design point on the  carabiner where the body meets the gate and locks. The keylock design locks securely and does not catch slings, ropes or harnesses. Opening and closing the carabiners is very simple. Carabiners with the keylock system are marked in the catalog with the symbol below.

Unique Identification Number:

Each carabiner has its own unique identification number within each manufacturing order. This number will improve registration and review of metal products during regular inspection checks.
