PACLOCK’s “81-Series” is engineered specifically for standard swing door trailer handles that are found on truck trailers, reefer trailers, toy haulers, car trailers, horse trailers, and equipment trailers (does not fit intermodal containers with ribbed handles, see PACLOCK’s “82-Series”). The lock body is machined in the U.S. from 6061 aircraft-grade aluminum and features a patented bolt cutter-proof hidden shackle design. Includes the PAC-BAND, a field-replaceable silicone cover to protect the cylinder from the elements.
