Deltana DSB4 4" x 4" Square Hinges (Pair)

No. The DSB4 is a residential duty hinge with a plain bearing barrel, which suits house interiors and residential entries rather than an opening that gets cycled all day. Plain bearing means the leaf rides on the knuckles themselves with no bearing race between them, so wear shows up faster under constant traffic or a heavy slab. For a commercial opening at the same 4 x 4 square corner size, Orca Hardware's 4040 Series is a medium duty plain bearing commercial hinge, and Delaney's CH401X is a 4 x 4 commercial ball bearing hinge with square corners. Ball bearing is the move when the door is heavy or the traffic is constant.

The DSB4 is 4 x 4 inches, the size normally hung on 1-3/4 inch exterior doors and heavier interior slabs. A standard 1-3/8 inch interior door usually runs 3-1/2 inch hinges, and putting a 4 inch leaf on that prep means widening and lengthening the mortise on both the door and the jamb. If you are matching an existing 3-1/2 inch prep instead, the Schlage Residential S3P1010 is a 3-1/2 x 3-1/2 square corner plain bearing hinge, and Emtek's 91013 is the same size and bearing type sold as a pair.

The Deltana DSB4 is a square corner hinge, so it will not seat in a radius pocket without recutting the mortise. At the same 4 inch size, the Orca Hardware 4014 Series is a 4" x 4" x 1/4" radius corner plain bearing commercial hinge, medium duty, which matches a 1/4 inch radius prep. For the 5/8 inch radius common on residential prehung doors, the Delaney RH45xx is a 4" x 4" exterior residential hinge with a 5/8" radius sold in pairs, and the Delaney RH40xx is a 4" x 4" residential pair listed as 5/8" radius by square for Castlegate doors. Measure the pocket corner before choosing between the 1/4 inch and 5/8 inch radius.

The Deltana DSB4 is not a non-removable pin hinge. On an outswing door the barrel sits on the exterior, so specifications for exterior and code-controlled openings usually call for NRP. The Hager BB1168 NRP is a full mortise ball bearing hinge with a non-removable pin, rated heavy duty, and it mortises into the door and frame the same way the full mortise DSB4 does. Use the BB1168 NRP where the pin side is exposed, and keep the DSB4 for inswing and interior openings where the barrel is on the protected side.

A pair is two hinges. Most residential doors hang on three hinges, so a single door takes two orders and you end up with one spare leaf in the same finish, which is worth holding onto. A tall or heavy slab specified for four hinges takes exactly two pairs with nothing left over. If you are ordering for a whole floor, count hinges per opening first and then convert to pairs rather than counting doors.

#12 x 1-1/4 inch wood screws are the specified fastener for the DSB4. That length lands in the jamb and door edge on a normal residential frame. On an exterior door it is standard practice to replace at least one screw per jamb leaf with a longer screw that reaches past the jamb into the rough framing, which is what actually stops a heavy door from sagging over time. Stay at #12 gauge for the rest; a smaller head does not fill the countersink in a solid brass leaf.

Solid brass, not a plated steel base. On a coastal or humid exterior opening that is the difference that matters, since a plated steel hinge eventually rusts through the plating at the knuckle where the finish is thinnest. Solid brass also means the unlacquered version can be polished back to bright if it darkens further than you want, which is not possible on a plated finish. For contrast, Emtek's 91013 residential plain bearing hinges are a plated steel product at 3-1/2 x 3-1/2.

Seventeen finishes: PVD Polished Brass, Polished Brass, Unlacquered Brass, Brushed Brass, Antique Brass, Polished Nickel, Brushed Nickel, Antique Nickel, Polished Chrome, Brushed Chrome, Oil Rubbed Bronze, Bronze Dark, Bronze Medium, Bronze is also where the shade matters most, White Dark, White Light, White Medium and Paint Black. Bronze and white each come in dark, medium and light, so if you are matching Deltana trim already on the job, match the shade word and not just the family name. Nickel and chrome each split into polished and brushed, and brass runs from PVD polished through to raw unlacquered.

Yes, and that is what it is for. Unlacquered brass carries no clear coat, so it darkens and patinas with handling and time, unevenly around the barrel and wherever hands land. The DSB4 offers it as a distinct finish choice alongside PVD Polished Brass, which is the opposite approach and holds its color. Order the unlacquered if you want the hinge to age into a period door; order PVD Polished Brass if you want brass that stays bright with no upkeep.

The Deltana DSB4 is a 4" x 4" hinge and will not drop into a 3-1/2 inch mortise. In 3-1/2 inch square corner with the same plain bearing action, the Emtek 91013 is a residential duty plain bearing pair in plated steel, the Schlage Residential S3P1010 is a 3.5" x 3.5" square corner plain bearing mortise hinge supplied as a pack of three, and the Ives 1010RP is a steel plain bearing residential hinge with square corners in a set of three, rated medium duty. All three match a 3-1/2 inch square pocket; the choice comes down to how many leaves you need per door and whether you want the plated steel or the brass look the DSB4 gives you.

Yes. The Delaney CH401X is a 4" x 4" commercial ball bearing hinge with square corners, so it uses the identical mortise footprint and corner prep as the Deltana DSB4. The single difference that matters for selection is the bearing: the DSB4 is a plain bearing hinge and the CH401X runs on ball bearings. Ball bearing hinges are the usual pick for doors that are heavy or that cycle constantly, such as a corridor or entry door in a rental building, while plain bearing suits interior residential swings.

The DSB4 is a plain bearing hinge with no closing action, so a door hung on it stays where you leave it. When the opening has to self close without a surface closer, the Stanley Security 2060R is a full mortise spring hinge with square corners in a 4.5" x 4.5" size on a ferrous steel base, rated heavy duty. It mortises into the door and frame the way the DSB4 does, but the leaf is 4-1/2 inch rather than 4 inch, so the existing 4 inch pocket has to be enlarged or the whole opening reprepped.

No - the DSB4 is a mechanical plain bearing hinge and hangs the door only. When the door leaf holds an electric strike, electrified lock or exit device that needs power through the hinge, the Command Access ETH-CB70 is a 3 knuckle standard weight steel base energy transfer hinge rated medium duty, and the BEST CECB179-12C is a steel full mortise concealed bearing electrified hinge with a 12 wire quick connect, also medium duty. If the access control system also has to know whether the door is open, the Command Access ETM-CB70 adds door position sensing on the same 3 knuckle steel base. Those replace one hinge in the set; the rest of the openings can stay on the DSB4.

The DSB4 is a full mortise hinge, which means both leaves are let into the door and the frame. Where the frame cannot be routed, the Hager 1129 is a half mortise plain bearing commercial hinge in 4-1/2 inch standard weight steel: the leaf mortises into the door edge and the other leaf applies to the face of the frame. Bearing action is the same plain bearing the DSB4 uses; the mounting method is what changes, so confirm the frame face has clearance for a surface applied leaf before ordering.

The DSB4 is a 4" x 4" plain bearing hinge that Deltana classes as residential. For a heavier or wider leaf, the Don-Jo HWBB84545 is a heavy weight full mortise ball bearing hinge in 4-1/2" x 4-1/2", and the Don-Jo HWBB75045 is a heavy weight full mortise ball bearing hinge in 5" x 4-1/2" steel for doors thick enough or wide enough to need the taller leaf. Both are heavy duty and both mortise in like the DSB4, but the 4-1/2 and 5 inch leaves need a larger pocket than a 4 inch prep.

The Deltana DSB4 is sold by the pair, so a door taking three hinges needs two pairs and leaves one spare, or three pairs across two doors. The Emtek 91013 and the Delaney RH45xx are also sold as pairs. The Schlage Residential S3P1010 comes as a pack of three and the Ives 1010RP as a set of three, which matches a single three hinge door exactly. Count the openings first: on a 40 door turn, buying in pairs versus sets of three changes how much you carry as leftover.

The Deltana DSB4 ships two to a pair, so a three-hinge door means buying two. If ordering in threes matters more than solid brass does, the Ives 1010RP is a steel plain bearing residential hinge with square corners sold as a set of three, and the Schlage Residential S3P1010 is a 3-1/2 x 3-1/2 square corner plain bearing mortise hinge in a pack of three. Both are steel rather than brass, so they are the choice for painted or utility openings, not for exposed decorative hardware.

The Deltana DSB4 is a solid brass 4" x 4" square corner hinge that may be fitted with decorative finials, which is why it shows up on entry and millwork doors where the barrel is seen. If the opening is prepped at 4-1/2 inch and you still want a decorative barrel, the McKinney SQ3331 is a square barrel 2 knuckle decorative hinge in 4-1/2" by 4-1/2", standard duty. The visual difference is the knuckle count and the square barrel profile against the DSB4 barrel with a finial fitted on top.

The DSB4 is a plain bearing full mortise hinge that Deltana classes as residential. On a commercial corridor door, the Ives 3CB1 is a 3 knuckle concealed bearing full mortise hinge rated medium duty, and the Ives 3CB1HW is the heavy weight version of the same 3 knuckle concealed bearing full mortise hinge, rated heavy duty. The Hager 920 is another route, a full mortise concealed plain bearing hinge with 2 knuckle steel construction at medium duty. All three mortise into the door and frame like the DSB4; what changes is the bearing arrangement and the duty rating you are specifying to.

No, and the mounting is usually the reason. The Hager 990 STEEL is a full surface prison hinge in 3" x 4" with a welded tip, heavy duty, and it fastens to the face of the door and frame rather than into a mortise the way the full mortise DSB4 does, so it needs no pocket but sits proud of the surface. The Stanley Security BB855 is a double weight prison hinge at 5" by 6" furnished with no holes and not swaged, meaning it is drilled and prepped on site, and the BEST BB855 is a heavy duty steel double weight concealed ball bearing prison hinge in the detention hardware line. None of them is a drop-in for a 4" x 4" square corner mortise.

The Deltana DSB4 is solid brass at 4" x 4". Staying non-ferrous in a larger commercial leaf, the McKinney T2314 is a non ferrous standard weight 5 knuckle hinge rated medium duty, and the Don-Jo HWBB85045 is a heavy weight full mortise ball bearing hinge with a brass base in 5" x 4-1/2", finished satin chrome and rated heavy duty. Both step outside the 4 inch square pocket the DSB4 uses, so plan the prep for the larger leaf. If the requirement is only about the look, the DSB4 brass hinge covers a wide finish range including polished nickel, oil rubbed bronze and polished chrome.
