FD-4020EILK Heavy-Duty 40" B-Rated Depository Drop Safe with Inner Locking Key Compartment & UL Listed Type 1 S&G Electronic Lock
The FD-4020EILK Depository Safe is a premium commercial drop safe designed for businesses requiring multi-tier internal cash security alongside rapid digital access. Engineered for high-volume retail locations, cash-handling businesses, and commercial offices, funds dropped through the front-loading drawer pass through an internal Anti-Fish Baffle directly into an integrated Inner Locking Compartment. This inner cash box is protected by key access, creating dual-level custody control so that managers opening the outer door cannot access dropped funds without the key.
The main outer vault door is secured by an advanced UL Listed Type 1 Sargent & Greenleaf (S&G) Electronic Lock, providing fast, user-friendly digital keypad access. Constructed with a heavy-duty 1/2" thick solid steel door, (7) 1-1/4" active solid steel locking bolts, an internal spring-loaded relocker, and a drill/ballistic-resistant hardplate, the 250 lb FD-4020EILK delivers maximum protection against burglary, drill attacks, and internal theft.

- Heavy-Duty Hinge-Side Dead Bar: Full-length solid steel dead bar locks firmly into the frame to prevent door removal during prying or hinge-grinding attacks.

Frequently Asked Questions
How does the FD-4020EILK differ from the FD-4020CILK model?
Both models feature identical 40" x 20" x 20" dimensions, 250 lb weights, 1/2" steel doors, and an inner key-locking compartment. The difference lies in the main door lock: the FD-4020EILK utilizes an S&G UL Listed Type 1 Electronic Keypad Lock for rapid PIN entry, while the FD-4020CILK features an S&G Group 2 mechanical combination dial lock.
How does the inner key-locking compartment work?
The interior lock box measures 9-3/4" H x 19-1/2" W x 15-1/4" D and receives all drops made through the upper drawer. It requires a key to access, allowing managers to open the outer digital door to access shelves or perform routine maintenance without gaining access to dropped cash.
What prevents cash from being fished back out through the drop chute?
The FD-4020EILK is built with an integrated Anti-Fish Baffle inside the drop drawer. Its internal sawtooth design physically prevents tools, wires, or tape from pulling cash envelopes or bags back up through the drop slot.
What are the interior dimensions and weight of the FD-4020EILK?
The FD-4020EILK weighs 250 lbs. The main interior space measures 19-5/8" High x 19-3/4" Wide x 16" Deep, and the internal key-locked box measures 9-3/4" High x 19-1/2" Wide x 15-1/4" Deep.
