The lock body has a semispherical shape and is made of thin iron with welded joints. Instead of a shackle, it has two projections on the bottom a few centimeters apart. The lock body is reinforced with steel ribs welded along the sides. The separate short end with the shackle is inserted to lock it. To unlock, the key is inserted in the opposite direction in the other short end. The detached end has one to four springs, and may have ward pins and guide pins making up the lock mechanism between the projections. The key has double shafts and a transverse bit with notches for the ward and guide pins and the ward springs. The space between the double shaft is also a part of the lock’s ward system.
