The Equipment Lock HDCDL steel cargo door lock is an adjustable-width, keyed lock made of steel to secure both doors of a semi-trailer or storage container. It is adjustable to fit doors with vertical locking bars from 9-3/4" to 16" apart. The lock is made of two square steel tubes, one 2" and one 2-1/2", with 3/16" thick walls, that fit together. The steel is powder-coated orange for high visibility and to help resist corrosion. The lock weighs 13 lb. and has 6" tall, 3/16" thick steel plates that are perpendicular to the tubes at their ends, and flush against the cargo doors, for added support.
