One type of safe that you can bolt to a wall is one that fits inside a wall. This type of safe is known as a wall safe. A wall safe can be concealed behind a picture or piece of art that is hanging on the wall. This means that you can install a safe into virtually any interior wall in your house. However, you will first need to obtain the correct size and type of safe to bolt to the wall.
Use a tape measure to find the width and height for the body of the safe that you want to install. The safe should be at least 14 inches wide, to fit between the wall studs.
Find the studs in the wall with the stud finder. Mark the location of the studs with a pencil.
Place a level on the wall and draw the outline of a square that matches the dimensions of the safe. Cut the outline with a drywall saw. Set the cut piece of drywall aside.
Place a ¼-inch strip of plywood against each stud. This will extend the stud so that it is flush with the cut edge of the drywall. Secure the plywood strip with nails, using the nail gun.
Open the door to the safe and Insert the it into the opening in the wall. Set the bottom edge of the safe first and then tilt the top into place.
Insert a screw into a mounting hole on the side of the safe. Secure the screw to the stud with the power drill. Repeat this step to secure the safe to the studs.
Install the shelves in the safe to complete the installation.
A 3-inch deep safe will fit into an interior wall. The width between wall studs is 16 inches.
Do not measure the lip of the save when obtaining the width and height.
