These intermodal container twist locks are the safety locking mechanisms which attach ISO containers to the container chassis (preferably) or flatbed at the corners.  Models available as non-retractable only.  Meet applicable requirements of Association of American Railroads (AAR) M-943 Section 5.3 for container restraints and American National Standard (ANS) Securements. 

These twist locks are easy to install: drop the body in the correct size hole and weld. The handle operates from lock to unlock either in a 70 or 90 degree arc in either direction.  Straight and Bent handle models.
