Deltana S35HD 3-1/2" x 3-1/2" Square Hinge, Heavy-Duty, Steel (Pair)

It fits if the mortise already there is 3-1/2 by 3-1/2 inches with square corners. The S35HD measures 3-1/2" x 3-1/2" and is cut square, not radiused, so it will not fill a pocket routed with the common 5/8 inch or 1/4 inch radius corners without rework. Older residential doors are frequently square-cut, newer factory-machined doors usually radiused. Check the corner of the leaf you are pulling off before you order.

Gauge. The S35HD leaf is .119 thick, where a standard residential hinge is thinner stock, and that extra material is what carries a solid core slab or a heavier door without the leaves splaying over time. Bearing style is unchanged: it is a plain bearing hinge, same as a basic residential unit, so it is the metal thickness you are paying for, not a bearing upgrade. If you want bearings under load, the Emtek 94013 is a heavy duty ball bearing hinge in the same 3-1/2 by 3-1/2 square corner size.

No. The S35HD is 3-1/2 by 3-1/2 inches and will leave the existing 4 inch mortise short at the top and bottom, plus the screw holes will not line up. Match the size you are pulling off. For 4 inch square corner openings, the Orca Hardware 4 x 4 square corner plain bearing hinge is the equivalent, or the Delaney CH401X 4 x 4 commercial ball bearing square corner if the door sees heavier traffic.

The S35HD is supplied without a non-removable pin. Where the barrel is exposed on the outside of the opening and the pin needs to be secured, the Hager BB1168 is a non-removable pin full mortise ball bearing hinge at heavy duty in the BB1168 series. Note it is a ball bearing hinge rather than plain bearing, so it is a different build than the S35HD, not a drop-in of the same hinge with a set screw added.

The Emtek 94013 is the ball bearing option in the same footprint: a heavy duty ball bearing pair, 3-1/2 inch by 3-1/2 inch with square corners in plated steel. The Deltana S35HD is a plain bearing hinge in that same 3-1/2 inch by 3-1/2 inch square corner size. If the opening is a heavier slab or a high-cycle door where a bearing race is called for on the drawing, the 94013 is the one to spec; the mortise cutout is identical.

The S35HD is a residential hinge - steel, plain bearing, 3-1/2 inch by 3-1/2 inch square corner, and Deltana describes the steel hinges as a value choice for indoor applications. For a commercial opening in the same 3.5 inch size, Orca Hardware's 3514 Series is a 3.5 inch by 3.5 inch plain bearing commercial hinge at medium duty, though it carries a 1/4 inch radius corner rather than a square corner, so the mortise prep is not interchangeable. Where the frame is already prepped square, the Orca 4040 Series square corner plain bearing commercial hinge is 4 inch by 4 inch and would need a larger cutout.

No. The S35HD has square corners, which needs a square corner mortise. For a 3-1/2 inch by 3-1/2 inch pair with a radius corner, the Delaney interior residential hinge in the Interior Residential Hinges series is 3-1/2 inch by 3-1/2 inch bulk steel with a 5/8 inch radius, sold as a pair. Corner style is the thing to confirm before ordering - the leaf size can match exactly and still sit wrong in an existing prep.

S35HD is sold by the pair, so a standard interior door hung on three hinges takes two pairs and leaves you a spare leaf, or order in twos across a job. Screws come with it: #10 x 1 inch wood screws, sized for a wood jamb and wood door. No separate fastener pack to add.

Plain bearing means the knuckles ride metal on metal with no bearing race between them. That is fine for a bedroom, bath, or closet door in a house or apartment. On a door cycling all day, a corridor, a restroom, a leasing office, the wear shows and the door starts to drop. Those openings want a bearing hinge instead, such as the Ives 3CB1 concealed bearing full mortise or a Don-Jo HWBB heavy weight ball bearing hinge.

Nine finishes, so the hinge can be matched to the lever and the rest of the trim on the opening: Polished Brass, Antique Brass, Oil Rubbed Bronze, Brushed Nickel, Antique Nickel, Polished Chrome, Brushed Chrome, Paint Black, and Prime Coat White. Prime Coat White is the one to order when the hinge is being painted out to match the door or casing, which is what most property managers standardizing a building end up doing.

Emtek 92013 is the closest match: heavy duty plain bearing hinges, sold in a pair, 3-1/2 by 3-1/2 inches with square corners, plated steel. Same size, same corner, same bearing type. If you want the lighter residential version of that, the Emtek 91013 is a residential plain bearing pair at the same size and corner. Schlage Residential S3P1010 is another 3-1/2 by 3-1/2 square corner plain bearing mortise hinge, but it comes as a pack of three rather than a pair, which is the more convenient count for a single door.

Yes, if you are re-prepping the opening. Staying square corner, the Orca Hardware 4040 Series is a 4 inch by 4 inch square corner plain bearing commercial hinge at medium duty, which keeps the plain bearing construction the S35HD uses at a larger leaf. The Delaney CH401X is a 4 inch by 4 inch commercial ball bearing hinge with square corner if you want a bearing race at that size. For a residential exterior door at 4 inch, the Delaney exterior residential hinge in the Exterior Residential Hinges series is 4 inch by 4 inch with a 5/8 inch radius, sold as a pair - that one is radius corner, not square.

No - the S35HD is a plain bearing steel hinge with no wiring provision. For power transfer through the hinge, the Command Access ETH-CB70 is an energy transfer hinge with a 3 knuckle standard weight steel base at medium duty, and the ETH-BB68 is the 5 knuckle heavy duty steel base version. If you also need door position sensing, the ETM-CB70 adds door position sensing on the 3 knuckle steel base and the ETM-BB68 is the energy transfer monitor hinge with an integrated door position switch at heavy duty. These are electrified hinges and carry their own wiring rough-in; the S35HD is a mechanical hinge only.

They cover the same size and corner: the Emtek 96213 is a heavy duty hinge sold as a pair, 3-1/2 inch by 3-1/2 inch with square corners, in the Heavy Duty Hinges series, and the Deltana S35HD is a 3-1/2 inch by 3-1/2 inch square corner heavy-duty pair. The S35HD is specified as steel with plain bearings and a .119 leaf thickness, and takes a #10 x 1 inch wood screw. Where the two part company is finish selection - the S35HD comes in nine finishes running from polished brass and antique brass through oil rubbed bronze, polished and brushed chrome, to paint black and prime coat white for painting to match.

For fleet standardizing on plain bearing square corner hinges, the Ives 1010RP is a steel plain bearing residential hinge with square corners sold as a set of 3, medium duty in the 1000 series. The Schlage Residential S3P1010 is likewise a 3.5 inch by 3.5 inch square corner plain bearing mortise hinge in a pack of 3. The Deltana S35HD covers the same square corner plain bearing steel construction in the heavy-duty build and ships by the pair, in nine finishes including oil rubbed bronze, brushed nickel, polished brass and prime coat white, which is the wider finish range if matching existing door trim is the driver.

Not in the same prep. 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, and the Don-Jo HWBB75045 is 5 inch by 4-1/2 inch steel in satin chrome. The Deltana S35HD is 3-1/2 inch by 3-1/2 inch. Both are full mortise, so the mounting method is the same idea, but the leaf sizes differ and the door and jamb would have to be re-mortised. If the 3-1/2 inch prep is already cut, stay in the 3-1/2 inch size.

No. The S35HD is a plain bearing full mortise hinge with no spring mechanism. For self-closing action, the Stanley Security 2060R spring hinge is a full mortise square corner spring hinge at 4.5 inch by 4.5 inch on a ferrous steel base, heavy duty. It shares the square corner and full mortise approach with the S35HD but sits at a larger 4.5 inch leaf, so it is a different mortise size as well as a different function.

No. The S35HD is a full mortise hinge, meaning both leaves mortise into the door and the jamb. For a half mortise condition, the Hager 1129 is a half mortise plain bearing commercial hinge, 4-1/2 inch standard weight steel, heavy duty. For a full surface application the Hager 990 STEEL is a full surface hinge, 3 inch by 4 inch with a welded tip, heavy duty plain bearing. Both keep the plain bearing construction the S35HD uses but mount to the face rather than into a mortise on both leaves.

Full mortise. Both leaves get let into the wood, one into the door edge and one into the jamb, so the hinge sits flush and only the barrel shows when the door is shut. That means routing or chiseling two pockets on a new install. On a half mortise or full surface hinge, one leaf screws flat to the frame instead, which is what you would want if the jamb cannot be cut.

No. The S35HD is a plain bearing hinge with no spring in the knuckle, so the door stays where you leave it. A self-closing opening, a garage-to-house door or a stairwell, needs a spring hinge such as the Stanley Security 4.5 x 4.5 full mortise square corner spring hinge, or a separate closer.

They are not the same class of hinge. The Ives 3CB1 is a 3-knuckle concealed bearing full mortise hinge at medium duty, and the Ives 3CB1HW is the heavy weight concealed bearing version; the McKinney MP79 MacPro is a 5-knuckle full mortise hinge at standard duty. All are full mortise like the S35HD, but they use concealed or architectural bearing constructions where the S35HD is a plain bearing steel hinge for residential use. Knuckle count and barrel height differ between these, so confirm the barrel matches the existing prep before treating any of them as a swap.
