Abstract
A loss-prevention device which operates by filling the hole of a lunette eye with a steel two-piece cylinder spool containing a barrel lock. Horizontal separation of the two pieces allows for the vertical removal from the lunette eye. When connected within the lunette eye, the device prevents attachment of the lunette eye's corresponding pentel hook and subsequent towing, hence, the name NO-TOW. This device can be manufactured in three sizes to accomodate the three sizes of lunette eye connectors currently in use.
