Product overview

SentrySafe SFW123DSB: What to Know

Per SentrySafe's own product page, the SFW123DSB combines a combination dial with a dual-key backup system, giving two independent ways to open the safe if you forget the combination or need a faster override. The company states it's UL Classified to withstand fire exposure up to 1700°F for a full hour and separately ETL-verified to keep contents dry after 24 hours submerged in up to 8 inches of water — two different independent certifications rather than a single combined rating.

Construction details from SentrySafe's spec sheet: solid steel body, four large steel locking bolts, and a pry-resistant hinge bar designed to resist forced entry. The interior includes an adjustable shelf, a key rack and a door pocket for organizing smaller items, and the unit comes with bolt-down hardware so it can be anchored to a floor or shelf.

SentrySafe's own materials list the exterior dimensions at 17.8 x 16.3 x 19.3 inches and a shipping weight of roughly 86 pounds — worth checking against your intended placement, since a safe this heavy isn't easily moved once installed, especially if bolted down.

Quick Answers

What's the difference between this dial-lock model and SentrySafe's digital-keypad safes?

Per SentrySafe's own product lineup, the core steel construction and fire/water ratings are similar across several SFW123 models, but the SFW123DSB specifically uses a mechanical combination dial with dual-key backup, while other SFW123 variants use a digital keypad instead. Choose based on whether you prefer a dial or a keypad as the primary access method.

Can this safe be used without bolting it to the floor?

Yes, per SentrySafe's materials the bolt-down hardware is included but optional — the safe's roughly 86-pound weight provides some inherent resistance to being carried off, though bolting it down adds meaningful theft resistance if that's a specific concern for your situation.
