Deltana DSB35R4-R 3-1/2" x 3-1/2" x 1/4" Radius Hinges, Solid Brass, Residential (Pair)

Corner style is what decides it. The DSB35R4-R has 1/4 inch radius corners on a 3-1/2 by 3-1/2 inch leaf, so it drops into a mortise routed with a standard 1/4 inch radius template. If the pockets in your door and jamb are square cornered, the radius hinge will leave a gap at each corner and you want a square corner hinge instead, like the Emtek 91013 residential plain bearing hinge in the same 3-1/2 by 3-1/2 size. Some jambs are cut with a 5/8 inch radius, which is a wider sweep than 1/4 inch and will also show a gap.

The DSB35R4-R is sold by the pair, so a standard interior door hung on three hinges takes two orders (you will have a spare leaf set) or a two hinge hang uses exactly one pair. Wood screws are included, #10 x 1 inch, which is a wood screw length meant for a wood jamb. If you are hanging into a steel frame or want a three hinge count in one purchase, the Ives 1010RP residential plain bearing hinge ships as a set of three.

Yes, and that matters for security. The DSB35R4-R is not a non-removable pin hinge, so on an outswing door the pin sits on the unsecured side and can be driven out. Keep it on interior and inswing doors. For an outswing exterior opening where pin removal is a concern, use an NRP hinge such as the Hager BB1168 NRP full mortise ball bearing hinge.

A 3-1/2 by 3-1/2 inch hinge like the DSB35R4-R is the standard for a 1-3/8 inch interior residential door. Exterior and 1-3/4 inch doors are normally hung on 4 inch or larger, because the wider leaf clears a thicker slab and carries more weight. If you are replacing a 4 inch hinge, do not drop to 3-1/2, the mortise will be short at both ends; the Orca 4014 Series in 4 by 4 with 1/4 inch radius corners keeps the same corner rout.

The Orca Hardware 3514 Series is the direct commercial counterpart in the same footprint: 3.5 inch by 3.5 inch with 1/4 inch radius corners and a plain bearing, rated medium duty. The Deltana DSB35R4-R shares the 3-1/2 inch by 3-1/2 inch size, 1/4 inch radius corners and plain bearing action, but is a solid brass residential hinge. If the door mortise is already cut for a 3-1/2 inch radius-corner hinge and the opening sees commercial traffic, the Orca 3514 drops into the same prep.

The Emtek 91013 is a residential plain bearing hinge pair in the same 3-1/2 inch by 3-1/2 inch size, built in plated steel. The Deltana DSB35R4-R is the same size and also plain bearing, but is solid brass and sold in a range of decorative finishes. The other difference that decides the mortise is corner style: the Emtek 91013 has square corners, while the DSB35R4-R has 1/4 inch radius corners, so the two are not interchangeable in an existing prep without rework.

No. The Deltana DSB35R4-R does not have a non-removable pin. For an out-swinging opening that calls for pin security, the Hager BB1168 is a non-removable pin full mortise ball bearing heavy duty hinge. That is a different class of hinge - heavy duty ball bearing steel rather than a residential plain bearing solid brass pair - so verify the leaf size and corner prep on the door before substituting.

No - it is a plain mechanical full mortise hinge with no wiring provision. To carry power to an electrified lock through the hinge, the Command Access ETH-CB70 is a 3-knuckle standard weight energy transfer hinge on a steel base, and the ETH-BB68 is the 5-knuckle heavy duty version. If the door also needs position monitoring, the Command Access ETM-CB70 adds door position sensing on the 3-knuckle body and the ETM-BB68 adds an integrated door position switch on the heavy duty body.

Plain bearing, which is what the DSB35R4-R uses, means the knuckles ride directly on each other with no bearing race. That is fine for a normal residential door of modest weight with intermittent use. Ball bearing or concealed bearing hinges exist because a heavy slab, a solid core exterior door, or a door with a closer on it will wear a plain knuckle and start to sag or squeak. If the door is heavy or gets constant traffic, the Emtek 94013 heavy duty ball bearing hinge or the Ives 3CB1 concealed bearing full mortise hinge are the step up in the same mounting style.

Full mortise only. Both leaves recess into pockets, one in the door edge and one in the jamb, so the hinge sits flush and the door closes tight to the stop. There is no surface mount option on this hinge. The screw holes run in an arc pattern rather than a straight line, which is the standard staggered layout that keeps the fasteners from splitting the same grain line in a wood jamb.

No handing to specify. A full mortise butt hinge of this type is symmetrical, so the same pair hangs a left or right hand door; you just flip it. The only orientation decision is which way the pin tip points, and since this hinge does not have a non-removable pin, keep the pin on the secure side of the opening.

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 3.5 inch by 3.5 inch square corner plain bearing mortise hinge sold in packs of three. Both are medium duty plain bearing. The Deltana DSB35R4-R is sold by the pair, so a three-hinge door takes a pair plus a single. Note the corner difference: the Ives and Schlage sets are square corner while the DSB35R4-R is 1/4 inch radius.

They serve different openings. The Ives 3CB1 is a 3-knuckle concealed bearing full mortise hinge rated medium duty, and the Ives 3CB1HW is the heavy weight concealed bearing version; the Hager 920 is a 2-knuckle concealed bearing full mortise hinge in steel, medium duty. All hide the bearing inside the knuckle for a smooth barrel on higher-cycle commercial doors. The Deltana DSB35R4-R is a residential plain bearing solid brass hinge whose appeal is the finish range and the option to fit decorative finials, which the concealed bearing steel hinges do not offer.

It depends on the leaf size the door is prepped for. The Don-Jo HWBB74545 and HWBB84545 are heavy weight full mortise ball bearing hinges at 4-1/2 inch by 4-1/2 inch in satin chrome, and the HWBB75045 and HWBB85045 are the 5 inch by 4-1/2 inch heavy weight versions. Those are heavy duty steel and brass hinges for wide or heavy commercial leaves. The Deltana DSB35R4-R is a 3-1/2 inch by 3-1/2 inch solid brass residential pair with plain bearings, sized for standard interior residential doors, so the two are not alternatives for the same opening.

Yes. The DSB35 solid brass hinges accept Deltana decorative finials, so the plain button tip can be swapped for a ball, urn, or steeple tip to match a traditional interior. Finials are ordered separately from the hinge pair and are the reason a lot of remodelers pick a solid brass hinge over a plated steel one on an exposed door.

The McKinney SQ3331 is a square barrel 2-knuckle decorative hinge at 4-1/2 inch by 4-1/2 inch, standard duty, and reads as a modern squared barrel on the door edge. The Deltana DSB35R4-R takes the other approach to appearance: solid brass in finishes from PVD Polished Brass and Antique Brass through Oil Rubbed Bronze, Polished and Brushed Chrome, Brushed and Antique Nickel, and it accepts decorative finials on the pin. Size drives the choice, since the SQ3331 is a 4-1/2 inch leaf and the DSB35R4-R is 3-1/2 inch.
