Depository safes, often referred to as drop safes or cash drop safes, are specialized safes designed to allow multiple individuals to deposit cash, checks, documents, or other small valuables into a secure compartment without having access to the main contents of the safe.1 This is a critical security feature for businesses and organizations that handle cash regularly.2
How Depository Safes Work
How Depository Safes Work
The core mechanism of a depository safe involves a drop slot, drawer, or rotary hopper through which items are inserted.3 Once deposited, these items fall into the main, locked compartment of the safe. A crucial component of these safes is an anti-fishing baffle or mechanism, which prevents anyone from reaching into the slot or drawer to retrieve items that have already been dropped.4
Only authorized personnel, typically managers or owners, possess the key or combination/code to open the main door of the safe and retrieve the accumulated deposits.
Key Features of Depository Safes
Key Features of Depository Safes
Deposit Mechanism:
Front-Loading Drop Slot: A simple slot on the front of the safe, ideal for envelopes or folded cash.5
Drawer Deposit: A pull-out drawer where items are placed.6 When the drawer is pushed in, the items drop into the safe. These are often used for bulkier items or larger quantities of cash.
Rotary Hopper/Drum: A rotating cylinder at the top of the safe that allows for larger, bulkier deposits, such as coin bags or cash trays.7
Through-the-Wall/Rear-Loading: The safe itself is secured in one room, and the deposit chute extends through a wall to another area, allowing deposits from a less secure zone into a highly secure one.8
Anti-Fishing Devices: Crucial baffles or jagged edges within the deposit mechanism prevent unauthorized retrieval of deposited items.9
Security Ratings:
B-Rated: A common standard for depository safes, meaning they have at least 1/8-inch steel body and 1/2-inch steel door (though some may use 1/4-inch body steel for higher security).
C-Rated: Offers higher protection with thicker steel (at least 1/2-inch body and 1-inch door).
Some safes may also have UL (Underwriters Laboratories) ratings for burglary resistance (e.g., TL-15, TL-30) for even higher security.10
Locking Mechanisms:
Mechanical Locks (Combination/Key): Reliable, no batteries required.11 (e.g., WELKO "KC" and "DK" series).
Electronic Locks (Keypad): Offer convenience with programmable codes, often with an emergency key backup.12 (e.g., WELKO "E" series).
Time Delay Locks: A feature that enforces a delay before the safe can be opened after the code is entered, deterring "smash and grab" robberies.13
Dual Control: Requires two separate keys or codes to open, increasing accountability.14
Fire Protection: Many depository safes also include fire-resistant materials, protecting contents from extreme temperatures during a fire (e.g., rated to withstand 1000°C - 1200°C for a certain duration).
Bolt-Down Capability: Most depository safes have pre-drilled anchor holes to allow them to be securely bolted to the floor, preventing thieves from carrying the entire safe away.
Construction: Heavy-gauge steel construction, often with reinforced doors, multi-directional locking bolts, and anti-pry features.15
Who Uses Depository Safes?

Retail Stores: To securely deposit cash throughout the day, minimizing cash register till levels and deterring internal and external theft.18
Restaurants & Bars: Similar to retail, for managing cash from transactions.
Hotels & Motels: For securing guest payments and valuables.19

Brands and Models of Depository Safes
Brands and Models of Depository Safes
WELKO Depository Safes (Vietnam):
As seen in your previous inquiries, WELKO offers a range of depository safes, typically indicated by "DK" in their model names. They combine traditional security with the convenience of a drop slot:
WELKO CSS820 DK Merah: A model you mentioned, featuring a red color and a mechanical lock with a depository function. Its specifications (820mm H x 530mm W x 400mm D, ~100kg weight, steel construction, fireproof rating 1000°C-1200°C) are typical for a medium-to-large depository safe.
WELKO's depository safes often feature:
Mailbox-style drop slot with anti-fishing baffles.22
Robust steel construction and fireproof capabilities.
Mechanical (KC/DK) or Electronic (E) lock options for the main door.
Anchor points for floor mounting.
LIBERTY Safe (USA):
Liberty Safe is primarily known for its high-quality gun safes and home safes, which prioritize fire protection and general burglary resistance.23 While they manufacture highly secure safes, their primary product lines don't prominently feature dedicated "depository" or "drop" safe models with built-in deposit slots in the same way that brands specializing in cash management safes do.
Liberty's focus is on:
Uni-Body Construction: For enhanced strength and pry resistance.
Thick Steel: Often 14-gauge or thicker.
Solid State™ Locking Bars: Unique, single-piece locking bars for superior pry resistance.
Advanced Fire Ratings: Ranging from 30 minutes to 2.5 hours at 1200°F (approx. 650°C), with heat-activated door seals.
UL Listed Locks: SecuRam electronic locks are common, with mechanical options also available.
Relockers: To secure the safe in case of forced entry attempts.
They offer various series (Centurion, Freedom, Colonial, Fatboy, etc.) with different levels of security and fire protection for general storage, including firearms, documents, and valuables.
If a "Liberty Safe" branded depository safe is encountered, it might be a specific commercial line not as widely advertised as their gun safes, or a model intended for general secure storage that happens to have a top opening or pull-out drawer that could be used for drops, but without the specific "anti-fishing" features of a dedicated depository safe. It's crucial to verify the exact model's features for any depository functionality.
"Church Safe" (General Term):
"Church Safe" is a descriptive term for safes suitable for church use. Depository safes are a very common type of "Church Safe" due to the need for secure cash collection. Other types of "Church Safes" might simply be general-purpose fire and burglary safes without a deposit slot, used for storing important records, valuable artifacts, or other assets that don't require frequent, unsecured deposits.
When choosing a depository safe, it's vital to consider:
The type and volume of items to be deposited.
The required level of security (burglary rating, lock type).
Whether fire protection is necessary.
The physical space available for the safe.
The frequency of main door access for cash collection.
