The anti-theft door is usually used for the entrance door (that is, the gate). Since it is a door lock installed at the gate, the size of the lock body should be 60*68mm standard anti-theft lock body. There are four lock tongues, and the four-fold anti-theft protection door. Considering that the door lock cannot be replaced frequently (time-consuming, damage to the door, waste of money, etc.), you should choose a harder one when choosing an anti-theft door lock body. For materials with high anti-theft and not easy to damage, the editor recommends to choose the anti-theft door lock body made of stainless steel 304, because stainless steel 304 meets the above requirements and is cost-effective.
