Twist Locks

Intermodal road twist locks are a component of flat bed road trailers or container trailer chassis (skeletal chassis). Twist locks lock ISO 1161 freight containers onto the vehicle. Twist locks come in many different designs and configurations. There are 2 main product design groups and 2 sub-groups: Retractable and Non-retractable. Both of these have the sub-groups of Screw-down or Non-screw down.
