Deltana DSB35 3-1/2" x 3-1/2" Square Hinge, Residential (Pair)

Residential. The DSB35 is a plain bearing hinge rated residential, which suits interior passage and bedroom doors in a house or apartment. For a commercial opening or a high-traffic door, go to a ball bearing or concealed bearing hinge instead, such as the Orca Hardware 3514 Series 3.5 x 3.5 inch plain bearing commercial hinge for light commercial, or the Ives 3CB1 concealed bearing full mortise hinge for medium duty commercial work.

Not without recutting. The DSB35 is a 3-1/2 inch hinge and a 4 inch mortise will leave a half inch of open pocket at the top and bottom of every leaf. For a 4 inch square corner opening, use a 4 inch hinge such as the Orca Hardware 4040 Series 4 x 4 inch square corner plain bearing hinge. 3-1/2 inch is the common size on 1-3/8 inch interior doors; 4 inch shows up on heavier and exterior slabs.

The pin is removable, so you can pull the pin and lift the door off without touching the screws. Handy for a painter or for moving furniture. The flip side: the DSB35 is not an NRP (non-removable pin) hinge, so on an out-swinging exterior door the barrel is exposed on the outside and the pin can be driven out. For that opening use a hinge with a non-removable pin, like the Hager BB1168 NRP full mortise hinge.

Both are 3-1/2 x 3-1/2 inch square corner plain bearing residential hinges sold in pairs, so they hang the same door in the same mortise. The difference is the base metal: the DSB35 is solid brass, the Emtek 91013 is plated steel. Solid brass for exterior, humid, or unlacquered patina applications and for finial compatibility; plated steel is the workhorse for interior doors. If you want the same size and square corner in a heavier plain bearing steel hinge, the Emtek 92013 is the heavy duty version.

Like-for-like. The DSB35 is a plain bearing hinge, the same class as most builder-grade residential hinges, so it will hang the door the same way in the same pocket but will not carry a heavier slab any better. If the door is sagging because the hinge is undersized for the weight, step to a ball bearing hinge in the same 3-1/2 inch square corner size, such as the Emtek 94013 heavy duty ball bearing pair. Pick the DSB35 when the reason for the swap is finish and solid brass, not load.

No. The DSB35 has square corners, and a square corner leaf will not seat in a radius-cut mortise without rework. For a 3-1/2 inch radius corner opening, the Orca Hardware COM3514 is a 3.5 by 3.5 hinge with a 1/4 inch radius corner and plain bearing, and the Delaney RH35xx is a 3-1/2 by 3-1/2 residential interior pair with a 5/8 inch radius. Match the radius to what is already cut in your jamb - 1/4 inch and 5/8 inch are not interchangeable.

The Emtek 91013 is the nearest match: a residential-duty plain bearing hinge pair, 3-1/2 inch by 3-1/2 inch with square corners, in plated steel. The Deltana DSB35 shares the 3-1/2 by 3-1/2 size, square corners, plain bearing, and residential rating, but is solid brass rather than plated steel, which is the difference to weigh if the finish has to hold up on an exterior or high-humidity opening.

The DSB35 is rated residential. For commercial openings, the Ives 3CB1 is a 3-knuckle concealed bearing full mortise hinge with a medium duty commercial rating, the 3CB1HW is the heavy weight steel concealed bearing version, and the Orca COM3535 is a 4-1/2 by 4-1/2 square corner ball bearing commercial hinge. Those step up in size and weight class, so confirm the leaf size against the existing jamb prep before ordering.

The DSB35 does not have a non-removable pin. When the opening needs the pin secured, the Hager BB1168 NRP is a non-removable pin full mortise ball bearing heavy duty hinge. Note it is a heavy duty hinge, so verify the leaf size suits the door before swapping it in for a 3-1/2 by 3-1/2 residential hinge.

No. The DSB35 is a mechanical full mortise hinge with no wire path. For power transfer through the hinge, the Command Access ETH-CB70 is a 3-knuckle standard weight energy transfer hinge on a steel base, the ETH-BB68 is the 5-knuckle heavy duty version, and the BEST CECB179-12C is a steel full mortise concealed bearing electrified hinge with a 12-wire quick connect. If you also need door position monitoring, the Command Access ETM-CB70 adds door position sensing on a 3-knuckle steel base.

Solid brass, both the base material and the substrate. That matters on an exterior or humid opening (a bathroom, a coastal house) where a plated steel hinge eventually rusts at the knuckle. Solid brass is also why the unlacquered brass finish will patina over time rather than staying bright.

Screws come with them: #10 x 1 inch wood screws. That length bites into a wood jamb and a wood door edge without blowing through. On an exterior or heavier door where you want the hinge anchored into the framing behind the jamb, swap the jamb-side center screw for a longer 3 inch screw in the same #10 size.

No handing to specify. The DSB35 is a symmetrical full mortise butt hinge with an arc hole pattern on both leaves, so the same hinge works on a left hand or right hand door. You just flip it. Order by size and finish only.

Eighteen finishes across the DSB35: oil rubbed bronze, dark bronze, medium bronze, rust bronze, dark white, light white, polished nickel, brushed nickel, antique nickel, black paint, polished chrome, brushed chrome, polished brass, unlacquered brass, PVD polished brass, brushed brass, antique brass, and rust. Property managers standardizing a building will find a match for most existing lever and knob lines here, and PVD polished brass is the one to pick if you want a bright brass that will not tarnish.

The leaf gauge is .119 inch. That is the number that decides whether it seats in an existing mortise flush with the jamb face. A thicker leaf sits proud and binds the door against the stop; a thinner one leaves the door sitting back. If you are replacing hinges in cut pockets, check what is in the door now against .119 before you order.

The DSB35 comes as a pair, one door's worth of two leaves, not a bulk carton. For fleet work where finish is not the point, a bulk residential option is easier to buy in volume: the Delaney RH35 3-1/2 x 3-1/2 inch bulk steel residential hinge with a 5/8 inch radius corner. Note the radius corner there, so it will not drop into a square corner mortise. Where your existing mortises are square, stay with a square corner hinge like the DSB35 or the Schlage Residential S3P1010 3-pack.

Yes. The Schlage Residential S3P1010 is a 3-1/2 by 3-1/2 square corner plain bearing mortise hinge sold in packs of three, and the Delaney RH35xx is a bulk steel residential interior hinge pair at 3-1/2 by 3-1/2 - though the Delaney uses a 5/8 inch radius corner, not a square corner, so it will not sit in a square-cut mortise. The Deltana DSB35 is the solid brass option in that size, offered in finishes from Polished Brass and Unlacquered Brass to Oil Rubbed Bronze and Polished Chrome.

Size and duty class. The DSB35 is a 3-1/2 by 3-1/2 residential plain bearing hinge in solid brass. The McKinney MP79 MacPro is a 5-knuckle standard weight full mortise hinge, and the Stanley FBB191 is a 5-knuckle full mortise standard weight hinge at 4.5 by 4.5. The larger 4-1/2 inch leaf needs a deeper and taller mortise, so it is a substitute only if you are cutting new prep or replacing a hinge that already measures 4-1/2 inches.

The DSB35 is a standard full mortise hinge with no closing mechanism. For self-closing, the Stanley 2060R is a full mortise spring hinge with square corners at 4.5 by 4.5 on a ferrous steel base. It shares the square corner and full mortise format but is a 4-1/2 inch leaf rather than 3-1/2, so the jamb and door prep have to be enlarged.

Not quite, and the difference is in how they are packaged. The Ives 1010RP is a steel plain bearing residential hinge with square corners sold as a set of three, while the Deltana DSB35 is sold as a pair. The bearing type, residential rating, and square corner match, but count the hinges per opening before you order - three-per-door and two-per-pair quantities do not line up.

A full mortise hinge like the Deltana DSB35 needs both the door edge and the jamb mortised. When only one side is prepped, the Hager 1129 is a half mortise plain bearing commercial hinge at 4-1/2 inch standard weight, and the Hager 990 STEEL is a full surface hinge at 3 by 4 with a welded tip. Half mortise and full surface mount differently, so match the hinge type to the prep you actually have.

It is a solid brass hinge offered in a wide finish range including Polished Nickel, Antique Nickel, Brushed Chrome, Antique Brass, and Oil Rubbed Bronze, and Deltana notes it may be fitted with decorative finials. If the opening calls for a decorative barrel profile in a larger size, the McKinney SQ3331 is a square barrel 2-knuckle decorative hinge at 4-1/2 by 4-1/2, which is a different leaf size and needs matching prep.
