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-2015 C/E 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. Can be installed in a 2" x 4" wall or a 2" x 6" wall. 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. This safe helps in the knowledge that even in the event of a burglary or robbery, your finances will be protected from theft. Having your depository safe mounted inside the walls of your building adds an element of reassurance that no one will be able to easily steal the entire safe.

There is an option for either a UL listed Group II Dial Combination Lock or an S&G Spartan Electronic Lock. The lock and relocker are protected by a drill/ballistic resistant hard plate.
