Locking Bars for Trailer and Container Doors
CSA offers 2 types of patented, high security Navalock steel locking bars to secure swing door trailers and sea containers, the MKIIB-L and MKIIIA. These bars secure the keeper rods on both doors, preventing removal of the handle hub to surreptitiously gain access to the contents. By sealing doors with locking bars after a tamper-evident seal is applied, truckers, railroads and freight forwarders can reaffirm the integrity of the doors after initial packing and sealing has been completed by the shipper. Locking bars are either designed for one-time use, requiring them to be cut off with appropriate tools and disposed of, or equipped with re-usable, keyed cylinder locks. Optionally, a numbered steel cable seal is applied to uniquely identify each load or use to establish and prove chain of custody.
