Deltana S35R5HD 3-1/2" x 3-1/2" x 5/8" Radius Hinge, Heavy-Duty, Steel (Pair)

If the existing mortise has 5/8 inch radius corners and is cut for a 3-1/2 by 3-1/2 inch leaf, the S35R5HD drops straight in. That corner radius is the thing to check first: most machine-prepped residential doors and jambs from the last few decades use 5/8 inch radius, but square-corner prep will leave gaps at the corners and radius prep cut at 1/4 inch will not accept a 5/8 inch leaf without rework. Measure the corner of the hinge already in the door before ordering.

No. The S35R5HD is a residential-duty steel hinge with a plain bearing, meant for indoor doors. Plain bearing hinges have no bearing race between the knuckles, so they wear faster under constant cycling than a ball or concealed bearing hinge. On an apartment interior door or a closet it is fine. On a leasing office entry, a corridor door, or anything on a closer, go to a bearing hinge such as the Ives 3CB1HW heavy weight concealed bearing full mortise hinge or the Don-Jo HWBB74545 heavy weight ball bearing hinge.

Not the right pick. These steel hinges are specified for indoor applications, and the pin is removable, which means anyone on the outside of an outswing door can drive the pin and lift the leaf off. For an out-swinging exterior or a unit entry door you want a non-removable pin hinge such as the Hager BB1168 NRP full mortise ball bearing hinge, or a hinge in a non-ferrous material that will not rust in a wet opening.

Gauge. The heavy-duty version runs .119 inch leaf thickness rather than the thinner standard residential stamping, so it holds a solid-core or heavier slab without the leaves flexing or the door sagging over time. Same 3-1/2 by 3-1/2 inch footprint and same 5/8 inch radius corners as a standard residential hinge, so it is a straight swap into the same prep. It is still a plain bearing hinge, so the upgrade is load capacity, not cycle life.

Wrong hinge for that. A plain bearing residential hinge is not built for the constant cycling a closer puts on it, and it carries no wire path, so it cannot feed power to an electrified lock or exit device. For a closer-equipped door use a bearing hinge like the Ives 3CB1HW. For power transfer through the hinge to an electric lock, use an energy transfer hinge such as the Command Access ETH-BB68, or the ETM-BB68 if you also need a built-in door position switch.

The Deltana S35R5HD is cut with 5/8 inch radius corners, which needs a pocket routed to that radius. For a pocket with square corners at the same 3-1/2 inch by 3-1/2 inch size, the Emtek 91013 residential plain bearing hinge and the Emtek 92013 heavy duty plain bearing hinge are both 3-1/2 inch by 3-1/2 inch plated steel pairs with square corners and plain bearings. The Schlage Residential S3P1010 is another square corner plain bearing mortise hinge at 3.5 inch by 3.5 inch, supplied as a pack of 3. Corner style is the item to confirm before ordering, since a square hinge will not seat in a radius pocket without chisel work.

The Deltana S35R5HD is a 3-1/2 inch x 3-1/2 inch steel full mortise hinge with 5/8 inch radius corners and plain bearings, sold as a pair. The closest match in another brand is the Delaney 3-1/2 inch x 3-1/2 inch bulk steel residential hinge, which is also a 3-1/2 inch by 3-1/2 inch steel residential hinge with 5/8 inch radius corners sold as a pair. Both share the same mortise pocket size and the same corner radius, so a Delaney RH35 series hinge drops into a pocket already routed for the S35R5HD without rework.

The Deltana S35R5HD is built at 3-1/2 inch by 3-1/2 inch. At 4 inch by 4 inch with the same 5/8 inch radius corner, the Delaney RH45 series is a bulk residential exterior hinge pair with 5/8 inch radius corners, and the Delaney RH40 series for Castlegate is a 4 inch by 4 inch pair offered in 5/8 inch radius and square. Moving up a leaf size means a wider mortise on both the door and the frame, so the 4 inch options are for a new cut rather than a swap into an existing 3-1/2 inch pocket.

The Deltana S35R5HD is a plain bearing steel hinge with no electrical provision. To carry power through the hinge, the Command Access ETH-BB68 is a 5-knuckle heavy duty steel base energy transfer hinge and the ETH-CB70 is a 3-knuckle standard weight steel base version. Where door position also needs to be monitored, the Command Access ETM-BB68 is an energy transfer monitor hinge with an integrated door position switch, and the ETM-CB70 adds door position sensing on a 3-knuckle steel base. BEST CECB179-12C is a steel full mortise concealed bearing electrified hinge with a 12-wire quick connect. Electrified hinges normally take the top or center position, with standard hinges carrying the rest of the opening.

No handing to specify. The S35R5HD is a symmetrical full mortise butt hinge, so the same pair works on a left hand or right hand door. The only thing you pick is finish. Handing only becomes an ordering question on hinges with electrical transfer or built-in switching, like the Stanley CECB1900R54L, which is sold left-handed.

Deltana's S35R5HD is the heavy-duty steel version at 3-1/2 by 3-1/2 with 5/8 inch radius corners, sold by the pair. For the same size and same 5/8 inch radius in a bulk interior residential pack, Delaney's 3-1/2 by 3-1/2 bulk steel residential hinge is the direct alternative. If the doors are 4 inch prep instead, Delaney's 4 by 4 bulk residential hinges come in 5/8 inch radius for both interior and exterior openings.

They are set up for wood. The S35R5HD ships with #10 x 1 inch wood screws and is a full mortise residential hinge, so it suits a wood door in a wood jamb. Hollow metal openings take machine screws into tapped frame prep, and typically a commercial-weight hinge. For steel frames look at a commercial full mortise hinge such as the Ives 3CB1 or the Orca Hardware 4-1/2 by 4-1/2 square corner ball bearing commercial hinge, matched to the frame's existing prep size and corner.

Heavier leaf, same footprint. The S35R5HD is the heavy-duty R5 build in Deltana's S35 Series at .119 inch thickness, in steel, while carrying the standard 3-1/2 by 3-1/2 inch size and 5/8 inch radius corners that builder-grade residential hinges use. That means you can upgrade a sagging solid-core door without recutting the mortise, which is the usual reason a property manager buys these instead of the base hinge.

The Deltana S35R5HD uses plain bearings, where the knuckles ride directly on each other. The Emtek 94013 is a 3-1/2 inch by 3-1/2 inch plated steel heavy duty hinge pair that uses ball bearings instead, and the Emtek 92013 is the heavy duty plain bearing version at the same 3-1/2 inch by 3-1/2 inch size. All three are square or radius variations on the same nominal leaf size, so the choice between them comes down to bearing type and corner style rather than pocket dimensions. Ball bearing construction is the usual specification where the door is heavy or the traffic is constant.

No. The Deltana S35R5HD is a 3-1/2 inch by 3-1/2 inch full mortise hinge, while the Don-Jo HWBB74545 is a heavy weight full mortise ball bearing hinge at 4-1/2 inch by 4-1/2 inch and the Don-Jo HWBB75045 is 5 inch by 4-1/2 inch. Those are larger leaf sizes and will not fit a pocket routed for a 3-1/2 inch hinge. The Hager BB1168 is a non-removable pin full mortise ball bearing heavy duty hinge, a different specification again since the S35R5HD does not have a non-removable pin. If the opening genuinely calls for a larger ball bearing hinge, the door and frame need to be prepped for it.

The Deltana S35R5HD is a plain bearing hinge with no spring, so a door hung on it stays where it is put. For a door that must return to the closed position on its own, 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. That is both a larger leaf size and a square corner, so the frame and door prep differ from a 3-1/2 inch radius pocket.

The Deltana S35R5HD mounts full mortise, meaning both leaves are let into the door and the frame. Where the frame cannot take a mortise, the Hager 1129 is a half mortise plain bearing commercial hinge, 4-1/2 inch standard weight steel, and the Hager 990 STEEL is a full surface prison hinge at 3 inch by 4 inch with a welded tip. For a door that must swing both ways, the BEST DAP-3 is a heavy duty double acting pivot for commercial interior doors, which replaces hinges altogether.

The Deltana S35R5HD is sold as a pair in a 3-1/2 inch by 3-1/2 inch steel residential hinge with 5/8 inch radius corners, offered in Oil Rubbed Bronze, Brushed Nickel, Antique Nickel, Paint Black, Polished Chrome, Brushed Chrome, Polished Brass, and Antique Brass. The Delaney RH35 series is a bulk 3-1/2 inch by 3-1/2 inch steel residential interior hinge pair with the same 5/8 inch radius, and the Ives 1010RP is a steel plain bearing residential hinge with square corners sold in sets of 3. The Deltana finish range is the reason to specify it where the hinges have to match existing decorative hardware across a building rather than disappear behind a paint grade door.

The Deltana S35R5HD covers 3-1/2 inch by 3-1/2 inch residential openings. Where the same building has 4 inch commercial doors, the Orca Hardware 4040 series is a 4 inch by 4 inch square corner plain bearing commercial hinge and the 4014 series is 4 inch by 4 inch with 1/4 inch radius corners, both medium duty plain bearing. The Delaney CH401X is a 4 inch by 4 inch commercial ball bearing hinge with square corners. Standardizing across a facility usually means matching bearing type and corner cut door by door, since the 5/8 inch radius on the S35R5HD is a residential cut rather than the 1/4 inch radius common on commercial frames.
