The mine consists of a rectangular metal container loaded with picric acid. A metal cover, which fits over the loaded container , rests on two pressuretypes igniters or fuzes. An aluminium safety bar prevents functioning of the igniter until removed, presumably after setting the mine in the ground.
The base plate has drilling at each corner to recieve the holding-down ugs. The cover is corugated and is strengthened internally by the two metal supports. The mine lid is held loosely in position by the mine-cover chains which are attached at either end to the base of the mine.
