Deltana S35-R 3.5" x 3.5" Square Hinge, Residential, Steel (Pair)

The S35-R is sold by the pair, so a standard interior door hung on three hinges takes two orders per door (one pair plus one more). Interior residential doors are commonly hung on three hinges; a lightweight closet or bifold slab is often fine on two. If you would rather buy in threes, the Schlage Residential S3P1010 is a 3-1/2" x 3-1/2" square corner plain bearing mortise hinge sold in packs of 3.

The S35-R is not a non-removable pin (NRP) hinge, so the pin can be driven out with the door closed. On an interior door that is a convenience, it is how you pull a door to move furniture. On any door where the hinge barrel ends up on the outside of a secured room, that is a security problem, and you want an NRP hinge instead, such as the Hager BB1168 non-removable pin full mortise ball bearing hinge.

A plain bearing hinge has the knuckles riding directly on each other with no bearing race. It is quiet and cheap and holds up fine on an interior door that gets opened a few times a day. A ball bearing hinge puts bearings between the knuckles so the hinge takes weight and high cycle counts without wearing the knuckles oval, which is what you want on a heavy slab or a door in a corridor. The S35-R is the plain bearing residential type. On the ball bearing side, the Emtek 94013 is a heavy duty ball bearing hinge in the same 3-1/2" x 3-1/2" square corner size, so it is a direct swap without touching the mortise.

For unit interior doors, bedroom, bath, closet, the S35-R does the job: residential plain bearing steel, 3-1/2" x 3-1/2" square corner, which is the size and corner profile most interior doors are already mortised for, so it goes in without recutting. Where it is the wrong pick is unit entry doors and any corridor or common-area door, since those want a ball bearing commercial hinge. If you want one hinge across a whole floor of interiors, standardize on a single finish and pull a pair off the shelf per door.

Not without filling and recutting. The S35-R leaf is 3-1/2" x 3-1/2", so it leaves a half inch of open mortise at each end of a 4 inch pocket and the screw holes land in the wrong place. Order a 4 inch hinge for that opening instead, such as the Orca Hardware 4" x 4" Square Corner Plain Bearing Commercial Hinge for square pockets, or the Delaney 4" x 4" residential hinge for a 5/8" radius pocket.

The Emtek 91013 is the same hinge in every dimension that matters at the door: a 3-1/2 inch by 3-1/2 inch square corner plated steel residential hinge with plain bearings, sold as a pair, matching the S35-R's 3.5 inch by 3.5 inch size, square corners, steel material and plain bearing construction. If you need the same size and corner in a three-piece pack instead of a pair, the Schlage Residential S3P1010 is a 3.5 inch by 3.5 inch square corner plain bearing mortise hinge sold in packs of 3.

Corner style has to match the existing mortise or you are recutting the jamb. The Deltana S35-R is square corner. For a 5/8 inch radius corner at the same 3-1/2 inch by 3-1/2 inch size, the Delaney RH35xx is a bulk steel residential interior hinge in 3-1/2 inch by 3-1/2 inch with a 5/8 inch radius, sold as a pair. For a 1/4 inch radius at the same size, the Orca Hardware COM3514 is a 3.5 inch by 3.5 inch plain bearing hinge with a 1/4 inch radius corner. Check which radius the frame was cut to before ordering, since 5/8 and 1/4 are not interchangeable.

Yes, and you can keep the same mortise. The Deltana S35-R is a residential duty plain bearing hinge. At the identical 3-1/2 inch by 3-1/2 inch square corner footprint, the Emtek 92013 is a heavy duty plain bearing hinge in plated steel, and the Emtek 94013 is a heavy duty ball bearing hinge, both sold as pairs with square corners. Ball bearing construction is the usual choice where the door cycles frequently or carries extra weight, since the bearing takes the load instead of the knuckle faces.

Yes, wood screws are specified with the hinge at #9 x 3/4", which is a wood screw sized for a door slab and a wood jamb. That length is short by design for the leaf, so if you are hanging a heavy slab you will usually want at least one longer screw per jamb leaf driven into the framing behind. The hole pattern is an arc pattern.

Leaf thickness is .085 inch. That is the gauge the mortise depth has to match, and it is worth checking against what is already in the door: swap in a thicker commercial leaf and the door sits proud and hits the stop, go thinner and you get a gap at the hinge edge. At .085 with square corners and 3-1/2" x 3-1/2" leaves, it is the standard residential builder hinge dimension.

No handing to specify. The S35-R is a full mortise butt hinge with a removable pin, so the same hinge hangs a left hand or right hand door. Order by size and finish only.

Ten finishes: Oil Rubbed Bronze, Polished Nickel, Brushed Nickel, Antique Nickel, Paint Black, Polished Chrome, Brushed Chrome, Polished Brass, Brushed Brass, and Antique Brass. That range is the practical reason to use the S35-R on a rehab, since you can match hinges to knobs and levers already going on the doors instead of settling for the two plated finishes a builder hinge usually comes in. All ten are the same steel hinge underneath.

The Deltana S35-R is 3-1/2 inch by 3-1/2 inch, so a 4 inch mortise needs a different part. In residential 4 inch by 4 inch, the Delaney RH45xx is a bulk exterior residential hinge with a 5/8 inch radius sold as a pair, and the Delaney RH40xx is a 4 inch by 4 inch residential hinge for Castlegate offered 5/8 inch radius by square, also a pair. For commercial 4 inch by 4 inch square corner, the Orca Hardware COM4040 is a plain bearing commercial hinge rated medium duty.

No, the S35-R is a plain bearing mechanical hinge with no wire path. Power transfer at the hinge takes a purpose-built part: the Command Access ETH-CB70 is a 3-knuckle standard weight steel base energy transfer hinge rated medium duty, and the ETH-BB68 is a 5-knuckle heavy duty steel base energy transfer hinge. If the opening also needs door position monitoring, the Command Access ETM-CB70 adds door position sensing on a 3-knuckle steel base at medium duty, and the ETM-BB68 is the heavy duty version with an integrated door position switch. The BEST CECB179-12C is a steel full mortise concealed bearing electrified hinge with a 12-wire quick connect, rated medium duty, for higher wire counts.

The S35-R is a steel residential hinge described for indoor applications, so exterior openings are worth matching to a hinge built for that duty. The Delaney RH45xx is a 4 inch by 4 inch bulk residential exterior hinge with a 5/8 inch radius corner, sold as a pair. Note the size and corner change with it: 4 inch by 4 inch radius rather than 3-1/2 inch by 3-1/2 inch square, so it is not a drop-in for an existing S35-R mortise.

No. The S35-R is a plain bearing full mortise hinge with no closing spring, so it holds the door where you leave it. If the opening needs the door to self-close, the Stanley Security 2060R is a full mortise spring hinge with square corners at 4.5 inch by 4.5 inch on a ferrous steel base, rated heavy duty. That is a larger leaf than the 3-1/2 inch S35-R, so the mortise has to be cut for it.

The S35-R is a full mortise hinge, meaning both leaves seat into cut mortises, one in the door and one in the jamb. Where only the door can be mortised, the Hager 1129 is a half mortise plain bearing commercial hinge, 4-1/2 inch standard weight steel, rated heavy duty. Where neither leaf can be mortised, the Hager 990 STEEL is a full surface prison hinge at 3 inch by 4 inch with a welded tip, rated heavy duty.

Full mortise. Both leaves recess, one into the door edge and one into the jamb, so the hinge is invisible with the door closed and the whole thing depends on having a pocket routed in each. If your door and frame are not mortised, a full mortise hinge means routing them. Half mortise and full surface hinges exist for that situation, like the Hager 1129 half mortise plain bearing hinge, which mortises to the frame and screws to the door face.

The S35-R has square corners on the leaf, but a conventional rounded barrel. If the visible barrel is the design decision, the McKinney SQ3331 is a square barrel 2-knuckle decorative hinge at 4-1/2 inch by 4-1/2 inch, rated standard duty. It is a larger leaf than the 3-1/2 inch by 3-1/2 inch S35-R, so it suits new mortises rather than a swap into existing ones. The S35-R covers the finish side of that decision instead, offered in Oil Rubbed Bronze, Polished Nickel, Brushed Nickel, Antique Nickel, Paint Black, Polished Chrome, Brushed Chrome, Polished Brass, Brushed Brass and Antique Brass.

The S35-R covers the 3-1/2 inch by 3-1/2 inch square corner residential interior side in steel, plain bearing, and carries ten finishes including Oil Rubbed Bronze, Brushed Nickel, Polished Chrome and Paint Black, so one finish can run across a floor. For the heavier corridor and entry openings, the McKinney MPB79 MacPro is a 5-knuckle standard weight hinge and the Stanley FBB191 is a 5-knuckle full mortise standard weight hinge at 4.5 inch by 4.5 inch rated heavy duty. Specifying one residential hinge and one heavier hinge, rather than a different part per door, keeps the stockroom to two line items.
