i have installed a few midrange gunsafes in houses i have lived in .i discovered trying to line up the holes in the back of the safe to wall studs is impossible so take a sheet of 3\4 in plywood cut it to the size of the back of the safe.then use long sheetrock screws and attach the plywood to the wall then use the safe lag bolts and attach safe to wood.when you remove the safe if you move a little sandpaper and small dabs of sheetrock mud and its all fixed
