Deltana DSB35B 3-1/2" x 3-1/2" Square Hinge, Ball Bearings (Pair)

If the existing mortise is 3-1/2 x 3-1/2 with square corners, yes. The DSB35B is a full mortise hinge measuring 3-1/2 by 3-1/2 inches with square corners, so it drops into a square-cut pocket of that size without rework. If your door and jamb are routed with rounded corners (the 5/8 inch or 1/4 inch radius you get from a template router), the square-corner leaf will not seat cleanly and you would need to square the corners with a chisel or pick a radius-corner hinge instead.

The DSB35B is sold as a pair, so one order covers two hinges. A typical interior door hangs on three hinges, which means you order two pairs and have a spare leaf left over, or you stay with two hinges on a light, short door. Screws are included in the sense that the hinge is drilled for #10 x 1 inch wood screws; there is no machine screw pack, so this is a wood jamb hinge, not a hollow metal frame hinge.

These are residential-rated hinges. Solid brass with ball bearings handles the weight and cycle count of a house or apartment door well, but for a commercial opening that sees constant traffic, go to a steel commercial hinge. The Orca Hardware 3535 Series is a 4-1/2 x 4-1/2 square corner ball bearing commercial hinge, and Ives 3CB1HW is a heavy weight concealed bearing full mortise hinge. Both are built for that duty; the DSB35B is not.

Usually not. Hinge height is picked off door thickness and width, and 3-1/2 inch hinges are the size for 1-3/8 inch interior doors. A 1-3/4 inch solid core or exterior door normally takes a 4 inch or 4-1/2 inch hinge so the leaf clears the door edge and the screws have enough purchase. For that opening look at a 4 x 4 or 4-1/2 x 4-1/2 hinge such as the Delaney CH401X 4 x 4 commercial ball bearing square corner hinge or the Orca 3535 Series 4-1/2 x 4-1/2 square corner ball bearing hinge. Keep the DSB35B for 1-3/8 inch interior doors.

The DSB35B is a residential duty hinge and it is not a non-removable pin hinge, so on an outswing opening where security of the exposed pin matters, specify a hinge built for it instead. The Hager BB1168 NRP is a non-removable pin full mortise ball bearing hinge at a heavy duty level. For an exterior residential opening without the NRP requirement, the Delaney Exterior Residential Hinges line runs 4 inch by 4 inch with a 5/8 inch radius corner, which is a different corner profile than the square corners on the DSB35B and needs matching mortise prep.

For light interior doors, the Emtek 91013 is a residential plain bearing hinge pair in 3-1/2 inch by 3-1/2 inch with square corners in plated steel, and the Schlage Residential S3P1010 is a 3.5 inch by 3.5 inch square corner plain bearing mortise hinge sold in packs of three at a medium duty level. Both drop into the same mortise footprint as the Deltana DSB35B, which is a 3-1/2 inch by 3-1/2 inch square corner hinge. The trade is bearing type: the DSB35B carries ball bearings, and those two carry plain bearings, which is the usual choice on doors that see occasional swings rather than constant traffic.

Step up to a 4-1/2 inch leaf. The Don-Jo HWBB74545 is a heavy weight full mortise ball bearing hinge at 4-1/2 inch by 4-1/2 inch in satin chrome, the Don-Jo HWBB84545 is the same size and finish in the 800 heavy weight line, and the Orca Hardware 3535 Series is a 4-1/2 inch by 4-1/2 inch square corner ball bearing commercial hinge at a medium duty level. For a taller leaf, the Don-Jo HWBB75045 is a heavy weight ball bearing hinge at 5 inch by 4-1/2 inch. All of these need a wider and deeper mortise than the Deltana DSB35B, which is a 3-1/2 inch by 3-1/2 inch full mortise hinge, so the jamb and door edge have to be prepped for the larger leaf.

Several ball bearing hinges in the set are built for a different job entirely. The Command Access ETH-BB68 and ETH-CB70 are energy transfer hinges that carry power through the hinge, and the ETM-BB68 and ETM-CB70 add door position sensing, so they belong on an electrified opening with wire prep in the frame. The BEST CECB179-12C is an electrified full mortise concealed bearing hinge with a 12-wire quick connect. The BEST BB855 and the Stanley double weight prison hinge are detention hinges. The Stanley 2060R is a spring hinge, which self-closes rather than swinging free. The Deltana DSB35B is a plain full mortise ball bearing hinge with no electrical or closing function, so none of those substitute for it on a standard door.

The Orca Hardware 3514 Series is a 3.5 inch by 3.5 inch commercial hinge at a medium duty level, matching the 3-1/2 inch by 3-1/2 inch leaf of the DSB35B. The catch is the corner: the Orca uses a 1/4 inch radius corner while the DSB35B is square corner, so the existing mortise decides which one seats correctly. The Orca also runs a plain bearing against the ball bearing in the Deltana.

Ball bearings sit between the knuckles and carry the door's weight on a rolling surface instead of metal rubbing on metal. On a heavy solid core or a slab hung with a closer, that is the difference between a door that keeps swinging quietly and one that starts to squeak and sag. The DSB35B is a 2BB (two ball bearing) hinge. On a light hollow core door a plain bearing hinge is enough, and the Emtek 91013 is a residential plain bearing hinge in the same 3-1/2 x 3-1/2 square corner size if you want to spend less on a closet or pantry door.

Twelve finishes: polished brass, PVD polished brass, unlacquered brass, brushed brass, antique brass, polished nickel, brushed nickel, antique nickel, polished chrome, brushed chrome, oil rubbed bronze, and paint black. For a property manager standardizing a floor or a building, that range covers most existing trim, and the PVD polished brass is the one to specify if you want the brass tone to hold up without polishing. Unlacquered brass is the opposite choice on purpose, it will patina over time.

The leaf is .119 inch thick. That thickness sets the mortise depth you rout and, with the leaves closed, the hinge-side gap between door and jamb. If you are swapping into a pocket cut for a thinner residential steel hinge, the door will sit slightly proud on the hinge side and may need the mortise deepened a touch. Cut the mortise so the leaf finishes flush with the door edge and the gap takes care of itself.

Material and construction. The DSB35B is solid brass through the whole leaf with ball bearings, which is why it takes a fine finish and why it can be left unlacquered to patina. The Delaney RH35 is a 3-1/2 x 3-1/2 bulk steel residential hinge with a 5/8 inch radius corner, which is what you buy by the case when you are hanging a subdivision's worth of doors and the hinge will never be looked at. Note the corner difference, the Deltana is square and the Delaney is radiused, so they are not interchangeable in an already-cut mortise.

No. The DSB35B is a plain mechanical hinge with no wire path through the barrel. To transfer power or monitor door position you need an electrified hinge: the Command Access ETH-CB70 is a 3 knuckle standard weight energy transfer hinge, the ETH-BB68 is the heavy duty 5 knuckle version, and the ETM series adds an integrated door position switch. Those are steel base commercial hinges, so plan on a commercial opening rather than a residential brass one.

All three are 3-1/2 inch by 3-1/2 inch square corner hinge pairs. The Emtek 92013 is a heavy duty plain bearing hinge in plated steel and the Emtek 96213 is a heavy duty hinge in the same size and corner. The DSB35B is a residential duty solid brass hinge running ball bearings. So the choice comes down to base material and bearing: brass body with ball bearings on the Deltana, plated steel with plain bearings on the 92013.

No. The DSB35B is a full mortise hinge, meaning both leaves mortise into the door edge and the jamb. For a half mortise opening the Hager 1129 is a half mortise plain bearing commercial hinge at 4-1/2 inch standard weight, and for a surface applied opening the Hager 990 STEEL is a full surface prison hinge at 3 inch by 4 inch with a welded tip. Mounting method has to match the prep already in the frame, since the leaf geometry differs.

The McKinney MP79 MacPro is a 5-knuckle full mortise hinge at standard weight, the MPB79 MacPro is a 5-knuckle standard weight hinge in the same family, the McKinney T2314 is a non-ferrous 5-knuckle standard weight hinge at a medium duty level, and the Stanley FBB191 is a 5-knuckle full mortise standard weight hinge at 4-1/2 inch by 4-1/2 inch. The T2314 is the one to look at when a non-ferrous body is wanted, since the Deltana DSB35B is solid brass rather than steel. Note the Stanley runs a 4-1/2 inch leaf against the 3-1/2 inch leaf of the DSB35B, so it is not a same-mortise swap.

The Ives 1010RP is a steel plain bearing residential hinge with square corners sold as a set of three at a medium duty level, so one carton covers a single door with three hinges. The Deltana DSB35B is sold as a pair in solid brass with ball bearings, also square corner, so a three-hinge door takes two orders and leaves a spare leaf pair. Corner style matches between them; the differences are bearing type, base material, and how many hinges come in a package.

Yes, the Deltana solid brass hinge line accepts decorative finials in place of the standard tips, so you can carry a ball, urn, or steeple tip through a set of doors where the hinge is visible. That is a real reason to choose solid brass over a plated steel commercial hinge on a front hall or a period restoration, where the hinge is part of the trim rather than just hardware.
