Many apartments, utility companies and schools use a through the wall drop safe for after hour drops or deposits. They can also be used for drop off of auto rental and dealership keys. The Hollon TTW-2015C Through The Wall Deposit Safe has a drop chute and hopper door for deposited items so they can be securely dropped through a wall and into the secure compartment. Also, when you own a business, you think about the safety of yourself and your staff as well as the security of your deposits and cash-on-hand.
