There are two reasons for bolting down a gun safe. One of them is to stabilize it, and counterbalance the door opening. The door is the heaviest part of a safe; when it opens, the vault can tip forward and cause serious injury. Besides, natural disasters like earthquake could knock over your gun safe. The second reason for anchoring a gun safe is security. Even the heaviest storage can be taken away by burglars. In order to prevent it from being stolen, you should bolt your gun safe down. It is also much harder to pry open safe’s door when it stands upright.
