Deltana SS35B-R 3-1/2" x 3-1/2" Square Hinge, Residential, Ball Bearing, Stainless Steel (Pair)

That's the reason to pick them. The SS35B-R is stainless steel through the leaf and pin, so it resists corrosion far better than a plated steel hinge on salt-air and waterside openings. Deltana positions the stainless line for exactly that: waterside properties and outdoor use. If you're a property manager replacing rusted hinges on beachfront units, this is the swap that stops the callback. Note it's rated residential duty, so it belongs on entry and interior doors of houses and apartments rather than a high-traffic commercial opening.

Not if you need pin protection. The SS35B-R does not have a non-removable pin, so on an out-swing door the barrel is on the outside and the pin can be driven out. For an out-swing entry where that matters, look at a hinge built with NRP, such as the Hager BB1168 non-removable pin full mortise ball bearing hinge. On an in-swing door the knuckle is protected on the inside and the standard pin is a non-issue.

No, not for a commercial opening. The SS35B-R is a residential-duty hinge and a 3-1/2 inch leaf is sized for lighter residential slabs. For corridor, stairwell, or tenant-facing commercial doors, step up to a commercial ball bearing hinge in a larger size, such as the Orca Hardware 3535 Series 4-1/2 x 4-1/2 inch square corner ball bearing commercial hinge, the Delaney CH401X 4 x 4 inch commercial ball bearing square corner hinge, or the Don-Jo HWBB84545 heavy weight full mortise ball bearing hinge at 4-1/2 x 4-1/2 inches. Use the Deltana inside the units, not on the building's traffic doors.

The Emtek 94013 is the nearest match on the same core geometry: it is a heavy duty ball bearing hinge pair at 3-1/2 inch by 3-1/2 inch with square corners in plated steel. The SS35B-R matches it on size at 3-1/2 inch by 3-1/2 inch, square corners, and ball bearing, but is built in stainless steel, which is why Deltana positions it for waterside properties and outdoor use where corrosion resistance matters. On an interior door away from salt air or weather exposure, the Emtek 94013 covers the same opening; on an exterior or coastal opening, the stainless base of the SS35B-R is the reason to stay with it.

The Emtek 91013 is a residential plain bearing hinge pair at 3-1/2 inch by 3-1/2 inch with square corners in plated steel, 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 keep the same 3-1/2 inch square corner mortise cutout the SS35B-R uses, so no door or jamb rework is involved. The difference is the bearing: the SS35B-R runs ball bearings, while the 91013 and S3P1010 are plain bearing. Ball bearings are what you want on a door that cycles often or carries weight; a low-traffic interior passage door is where the plain bearing versions apply.

For a 4 inch square corner mortise cutout, the Orca Hardware COM4040 is a 4 inch by 4 inch square corner plain bearing commercial hinge, and the Delaney RH40xx is a 4 inch by 4 inch residential pair offered in 5/8 inch radius and square corner. If the opening needs ball bearings at that size, the Delaney CH401X is a 4 inch by 4 inch commercial ball bearing hinge with square corners. The SS35B-R is built at 3-1/2 inch by 3-1/2 inch only, so a 4 inch leaf cutout requires one of these rather than a finish or pin change.

Not a drop-in one. The Orca COM3514 is a 3.5 inch by 3.5 inch commercial hinge, so the leaf size matches the SS35B-R, but it is a 1/4 inch radius corner plain bearing hinge. The SS35B-R has square corners and ball bearings. A radius corner leaf will not sit correctly in a square corner mortise cut by a router template or a chisel, and the reverse leaves gaps at the corners, so corner style has to be confirmed against what is already routed into the door and jamb before ordering either one. If the existing pockets are square, the COM3514 is the wrong corner profile regardless of the matching dimension.

The SS35B-R is designated residential. For a commercial opening, the Ives 3CB1HW is a steel heavy weight concealed bearing full mortise hinge with 3 knuckles, and 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. Both are heavy duty rated. Note the size step: those run larger leaves than the 3-1/2 inch by 3-1/2 inch SS35B-R, so the door and jamb have to be prepped for the wider cutout. Where the opening genuinely stays at 3-1/2 inch and only needs more capacity, the Emtek 96213 is a heavy duty hinge pair at 3-1/2 inch by 3-1/2 inch with square corners, keeping the existing mortise.

The SS35B-R is not a non-removable pin hinge. For an out-swinging exterior or secured door where the pin must not be drivable from the hinge side, the Hager BB1168-NRP is a non-removable pin full mortise ball bearing heavy duty hinge. It keeps the full mortise mounting method and ball bearing action of the SS35B-R while adding the NRP set screw feature. Locksmiths and security integrators specifying for an out-swing leaf should go to the BB1168-NRP; the SS35B-R suits in-swinging openings where the barrel is on the protected side.

Ball bearings sit between the knuckles and carry the door's weight on a rolling surface instead of metal rubbing metal. On a heavier slab, a solid-core or exterior door, or one with a closer on it, that means a quieter swing and much less wear at the knuckle over years of cycles. The SS35B-R is a ball bearing hinge. Plain bearing is the cheaper choice for a light hollow-core interior door that gets opened a few times a day; ZenSupply carries the Emtek 91013 and the Schlage Residential S3P1010 in the same 3-1/2 inch square corner size as plain bearing options.

No. Full mortise butt hinges like the SS35B-R are non-handed, so the same pair works on a left-hand or right-hand door. You flip the hinge to suit the swing. Handing only becomes an ordering decision on spring hinges or electrified hinges with a fixed wire side, like the Stanley CECB1900R54L, which is specified left-handed.

The leaf gauge is .085 inch. That's the number to check against your existing hinge if you're swapping into an already-routed mortise, because a thicker leaf will make the door sit proud of the jamb and a thinner one leaves the door hanging back. Set the pocket depth to the leaf thickness and the door closes flush.

Visually and functionally, they'll match anything else that is 3-1/2 x 3-1/2 inch with square corners, so on a fleet of units where the doors were prepped the same you can replace door by door as they fail rather than doing a whole building at once. What won't match is the metal: brushed stainless reads cooler and grayer than a plated satin nickel or satin chrome hinge sitting next to it on the same jamb. Keep the swap consistent per opening, all three hinges on one door at a time.

It comes down to exposure. A plated steel hinge is fine on a protected door under a deep porch or in a dry climate, and options like the Emtek 94013 heavy duty ball bearing hinge in 3-1/2 inch square corner plated steel or the Delaney RH45xx exterior residential hinge cover that. Once you're near salt water, a pool deck, or an opening that takes weather directly, the plating is the failure point: it gets nicked, the steel underneath rusts, and the hinge stains the jamb. The Deltana SS35B-R is stainless all the way through, which is why it goes on waterside and outdoor openings.

Both are 3-1/2 inch by 3-1/2 inch residential hinges sold as a pair, so quantity and leaf size line up. The differences that decide it are corner and material. The Delaney RH35xx is a bulk steel residential hinge for interior use with a 5/8 inch radius corner; the SS35B-R has square corners and a stainless steel base that Deltana points at waterside properties and outdoor use. For a run of interior bedroom and closet doors already routed with radius pockets, the RH35xx matches the prep. For an exterior or coastal-exposure door with square pockets, the SS35B-R is the one that fits both the cutout and the environment.

No. The SS35B-R is a mechanical stainless steel ball bearing hinge with no conductor path. To carry power or signal through the hinge, the Command Access ETH-CB70 is an energy transfer hinge on a 3 knuckle standard weight steel base, and the ETM-CB70 adds door position sensing to the same 3 knuckle steel base build. If the opening also needs door position monitoring, the ETM-CB70 handles both in one leaf. Plan for these to be specified alongside standard hinges on the same door rather than replacing every hinge in the set.

The SS35B-R is a standard full mortise hinge with no closing mechanism. Where the leaf has to return on its own without a surface closer, 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. The square corner profile is shared with the SS35B-R, but the 4.5 inch leaf is larger than the 3-1/2 inch by 3-1/2 inch SS35B-R, so the door and jamb need the deeper and taller mortise before it will fit.

Watch the count and the bearing before treating them as equivalent. The Ives 1010RP is a steel plain bearing residential hinge with square corners sold as a set of three, while the SS35B-R is supplied as a pair. On a door taking three hinges, one 1010RP set covers the leaf and one SS35B-R pair does not. The 1010RP is also plain bearing against the ball bearing build of the SS35B-R. Corner style matches on both, so the mortise prep carries over; the quantity math and the bearing choice are what need confirming on a multi-door order.

Both are 3-1/2 inch by 3-1/2 inch square corner hinge pairs, so they interchange in the same mortise. The Emtek 92013 is a heavy duty plain bearing hinge in plated steel; the SS35B-R is a residential ball bearing hinge in stainless steel. Two separate decisions sit inside that: bearing type, where ball bearings suit doors that cycle frequently or hang heavy, and base material, where the stainless build of the SS35B-R is aimed at outdoor and waterside exposure. A heavy interior slab in a dry location points to the 92013; a weather-exposed opening points to the SS35B-R.

The Orca Hardware COM3535 is a 4-1/2 inch by 4-1/2 inch square corner ball bearing commercial hinge at a medium duty level. It shares the square corner profile and ball bearing action with the SS35B-R but moves to a commercial build and a 4-1/2 inch leaf, against the 3-1/2 inch by 3-1/2 inch of the SS35B-R. That size change means new door and frame prep, so it fits new construction or an opening being reworked rather than a straight pull-and-replace on doors already cut for 3-1/2 inch hinges.

Brushed stainless is the finish, which is a satin gray tone that pairs with satin nickel and brushed chrome trim without trying to match it exactly. Since the base metal is stainless rather than plated steel, the surface won't rust through the way a plated finish does when it gets scratched on an exterior opening. That matters more than color on a coastal or poolside door.

Holes are arranged in an arc rather than in a straight line down the leaf. The staggered arc spreads the screws across more of the wood grain, which reduces the chance of splitting a stile and gives better pull-out in a door edge. If your old hinge had inline holes, expect to drill fresh pilots rather than reuse the existing ones. Pilot for the supplied #10 x 1 inch wood screws.

They solve a different problem. The BEST BB855 is a heavy-duty steel double weight concealed ball bearing prison hinge in the detention hardware line, and the Hager 990 STEEL is a full surface prison hinge at 3 inch by 4 inch with a welded tip. Those are built for attack resistance on detention openings, with full surface mounting in the Hager case rather than the full mortise prep the SS35B-R uses. A residential or light commercial door that just needs a secure pin does not need detention hardware; a non-removable pin hinge covers that requirement without the frame and door prep these demand.
