> Twistlocks are mechanical fastening devices used to secure ISO containers in intermodal transport.

Twistlocks are mechanical fastening devices used to secure ISO containers in intermodal transport. They engage the standardized corner castings of a container and lock in place through a quarter-turn, creating a positive, form-fitting connection between the container and its support structure – whether a ship's cell guide, a rail wagon, or a road chassis. This prevents shifting, tipping, or lifting during vessel motion, shunting, or road travel. Twistlocks come in active (manually operated), passive (self-locking on placement), and semi-automatic variants, each suited to specific handling environments and equipment types. They are a globally standardized component of cargo securing in container logistics.
