A twistlock or twist lock, together with matching corner castings, as defined in norms including ISO 1161:1984, form a standardized (rotating) connector system, for connecting and securing intermodal, and predominantly ISO-standard international shipping containers. The primary uses are to securely stack containers, for locking them into place on a container ship, semi-trailer or rail carriage, and for lifting and handling by specific container-handling equipment, like straddle carriers, reach stackers, container-handling forklifts, sidelifters, and various types of container cranes.
