Choose SentrySafe for hanging folders and a key lock; choose DocSafe for lighter storage with a grab handle and combination lock. In this SentrySafe vs DocSafe comparison, the right fit depends on how you organize documents, how you want to access them and whether you may need to carry the box.
The SentrySafe HD4100 is a 0.65 cu ft file box that fits hanging folders. It weighs 38.8 lb and uses a key lock.
The DocSafe DS0122 is a shorter organizer with 660 cubic inches of capacity, a combination lock and grab handle. It weighs 2.56 kg and has a water-resistant design.
SentrySafe vs DocSafe: which box fits your papers?
SentrySafe is the better match for hanging folders; DocSafe is the better match for flat, compartmentalized storage. Think about the papers you keep and how you want to sort them before choosing by exterior size.
The HD4100 has an interior 12 in wide, 8.1 in deep and 11.5 in high. Its design fits hanging file folders, which can keep records grouped and upright.
The DS0122 has an interior 14.8 in long, 10.6 in wide and 3.9 in high. It comes with a removable compartment and is shaped for documents, cards and other small items rather than upright hanging folders.
These are not directly comparable capacity figures: one is given in cubic feet and the other in cubic inches. For specific forms or folders, measure a packed sample and compare it with the interior dimensions before deciding.

Which has more practical fire protection?
SentrySafe gives a specific UL Classified duration claim; DocSafe describes its materials and a flame-retardant test. Read those statements as different kinds of information, not as matching ratings.
SentrySafe says the HD4100 is UL Classified to withstand high temperatures for up to 30 minutes. This gives you a stated duration to consider for paper storage.
DocSafe describes 12 layers of heat-insulating materials and says the box passed the UL94 V-0/5VA flame-retardant test. It also gives a temperature claim, but that is not the same type of claim as SentrySafe's UL Classified duration.
A flame-retardant material test does not by itself tell you how long documents inside a closed box will stay within a safe temperature range during a house fire. Compare the exact certification and test details that matter for your situation.
Our guide to fireproof safe ratings explains how to read rating language and why time claims matter. You can also read whether fireproof safes work in a house fire before choosing a box for irreplaceable records.
How do their water claims compare?
SentrySafe has an ETL Verified water-exposure claim, while DocSafe is described as water-resistant. Neither phrase should be treated as a promise that the box can withstand every flood or length of submersion.
SentrySafe says the HD4100 is ETL Verified to protect contents during water exposure. That makes it the clearer fit if you want a box with a specific verification statement about water.
DocSafe describes the box as water-resistant and says it is intended to help protect contents during flooding or humid weather. It does not have a matching ETL verification claim in the product information here.
Water can enter through seams or closures, and the conditions of an incident vary. If water protection is a key reason for buying, compare the exact test conditions and limits for both models before relying on either.
For help sorting out terms, see fire and water resistant safes. That guide can help you decide which protection claim deserves the most weight for the records you store.
Which lock and access style suits you?
Choose the HD4100 if you prefer a key; choose the DS0122 if you prefer a combination lock. The right choice is the one you can open when you need your papers.
The SentrySafe uses a key lock and includes 2 keys. Store the spare somewhere separate but accessible to the people who may need to retrieve documents.
DocSafe uses a combination lock. You won't need to keep a key nearby, but you should store the combination in a secure place you can access if you forget it.
Neither lock choice replaces a suitable storage plan. Keep emergency records findable, and make sure anyone who may need them knows how to access the box.
Which one is easier to move?
DocSafe is the easier choice for frequent carrying because it weighs 2.56 kg and has a grab handle. The HD4100 weighs 38.8 lb, so it is better suited to a place where you plan to leave it.
DocSafe has a grab handle and is lighter than the HD4100. Its slim shape suits a document organizer for home, office or travel storage.
SentrySafe is described as portable enough to relocate when needed, but its weight makes moving it a more deliberate job. Plan its location before loading it with important papers.
If you expect to move the box during an emergency, consider who will carry it and whether the route includes stairs. A loaded container can be harder to manage than its empty weight suggests.
What should you choose for a home office?
Choose SentrySafe if you maintain paper files; choose DocSafe if you keep a smaller, flatter set of essentials. The HD4100's hanging-folder fit supports a filing routine, while DocSafe's compartments suit a compact document set.
The SentrySafe box measures 13.5 in deep, 15.5 in wide and 14.3 in high. Its compact footprint is designed to fit in a closet, office or under a desk, though you should measure the space and the route into it.
DocSafe measures 15.5 in long, 11.8 in wide and 5.12 in high externally. That lower profile may fit a shelf or drawer more easily, but check the interior height against your papers and folders.
If neither format suits your storage, browse our SentrySafe fireproof box model guide. It explains how the brand's different boxes serve different paper-storage needs.
SentrySafe vs DocSafe: which should you pick?
Pick SentrySafe for hanging folders and a stated fire duration plus ETL Verified water-exposure claim; pick DocSafe for lighter storage with a combination lock. Your document format and plans for access should settle the choice.
The HD4100's strongest fit is a home filing system where weight is less important than folder organization. The DS0122 makes more sense when you want a compact organizer you can carry more easily.
If protection ratings are the deciding factor, compare the fire and water claims carefully and read how fireproof safe ratings work. For a broader brand comparison, see fireproof safe brands compared.
