Safe accessories are easy. If your safe doesn't come with a factory dehumidifier, get one they're cheap and easy to install and they will keep your guns from rusting. If your safe doesn't come with a factory light kit, get one they're cheap and easy to install and without lighting it can be difficult to see your stuff. Door organizers, and pistol racks are two of the biggest interior space savers you can add to your safe. Bolt down kits are essential if your safe is going in a garage, or shop with a large bay door, or if you have a smaller home or office safe weighing less than say 500 lbs. If it's bolted down in all four corners with concrete bolts, it's not going anywhere very easily. All of these options again, are cheap and easy to install. It's a good idea to go ahead add them now, before your safe is filled all your stuff. If you add them later you will have to remove all your stuff before you do the job, believe me I've installed many safes and it's much easier to work on an empty safe with plenty of room.
