Deltana SS44B 4" x 4" Square Corner Hinge, Ball Bearing, Stainless Steel (Pair)

That is what the SS44B is built for. It is solid stainless steel through the leaf and substrate, and Deltana calls out stainless as the choice for waterside properties and outdoor use because it resists corrosion far better than a plated steel hinge. On a coastal or poolside entry door, a standard steel hinge will streak and seize at the barrel long before a stainless one does.

The SS44B measures 4 x 4 inches with square corners, so it drops in only if the existing mortise is also 4 x 4 with square (not radiused) corners. Most factory-prepped doors and steel frames are cut with a 1/4 inch or 5/8 inch radius instead, and a square corner hinge will not seat in a radiused pocket without squaring the corners with a chisel. Pull one hinge off and look at the corner of the pocket before you order.

You can hang it, but the pin is removable. The SS44B is not an NRP hinge, so on an out-swing door the hinge pins sit on the outside and can be driven out. If that opening needs to resist that, use a non-removable pin hinge such as the Hager BB1168 NRP full mortise ball bearing hinge, or add hinge pin studs. On an in-swing door the pins are protected and this is a non-issue.

Residential. The SS44B is a residential-duty full mortise hinge, which suits houses, apartments, and light entry doors in multi-family. For a commercial storefront, office, or institutional opening that sees constant traffic, step up to a commercial ball bearing hinge like the Orca 3535 Series 4-1/2 x 4-1/2 square corner ball bearing hinge, the Delaney CH401X 4 x 4 commercial ball bearing square corner hinge, or a heavy weight Don-Jo HWBB84545 at 4-1/2 x 4-1/2.

Not without recutting. The SS44B is a 4 x 4 hinge, and a 3-1/2 inch mortise is both shorter and shallower in leaf width, so the larger hinge will stand proud and the door will not close. Either deepen and lengthen the pocket in both the door and the jamb, or stay at 3-1/2 inches with something like the Emtek 94013 heavy duty ball bearing pair or the Schlage Residential S3P1010 square corner mortise hinges. Going the other way, a 4 inch pocket will happily accept a 4 inch hinge with square corners.

The Deltana SS44B has square corners, so it will not drop into a radius-prepped mortise without filing the corners of the pocket. For a 4 inch by 4 inch mortise with a 1/4 inch radius, the Orca Hardware 4014 Series is a 4 inch by 4 inch, 1/4 inch radius corner plain bearing commercial hinge in medium duty. For a 5/8 inch radius prep at the same 4 inch size, the Delaney RH45xx is a 4 inch by 4 inch residential exterior hinge with a 5/8 inch radius, sold in pairs. Confirm which radius the existing prep uses before ordering, since 1/4 inch and 5/8 inch are not interchangeable in the same pocket.

No. The SS44B is a plain mechanical hinge with no wiring path. For power transfer 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 energy transfer hinge in medium duty. If the opening also needs door position monitoring, the Command Access ETM-BB68 is an energy transfer monitor hinge with an integrated door position switch in heavy duty, and the ETM-CB70 adds door position sensing on a 3-knuckle steel base. The BEST CECB179-12C is a steel full mortise concealed bearing electrified hinge with a 12-wire quick connect in medium duty, and the Stanley CECB1900R54L is a 3-knuckle concealed bearing concealed conductor hinge, steel full mortise standard weight, 4-1/2 inch by 4-1/2 inch, square corner, left-handed, 4-wire. Wire count and handing have to match the device you are powering.

The Orca Hardware 3535 Series is a 4-1/2 inch by 4-1/2 inch square corner ball bearing commercial hinge rated medium duty, and the Delaney CH401X is a 4 inch by 4 inch commercial ball bearing hinge with square corners. The Delaney matches the SS44B on size and corner style at 4 inch by 4 inch square corners with ball bearings; the Orca carries the same ball bearing action and square corners but in the larger 4-1/2 inch leaf, which needs a wider mortise and a deeper door edge. The SS44B differs from both in base material: it is stainless steel, which Deltana positions for waterside and outdoor exposure.

Yes. The Orca Hardware 4040 Series is a 4 inch by 4 inch square corner plain bearing commercial hinge in medium duty, and it keeps the same 4 inch square leaf and mortise footprint as the Deltana SS44B while using a plain bearing instead of the SS44B ball bearing. On a low-traffic interior door carrying a hollow-core or light panel slab, the plain bearing is the usual choice; the ball bearing in the SS44B is what carries repeated cycling and heavier slabs without the knuckle wearing.

The SS44B is a 4 inch by 4 inch hinge and will not fit a 3-1/2 inch prep. At 3-1/2 inch by 3-1/2 inch with square corners, the Emtek 94013 is a heavy duty ball bearing hinge sold in pairs in plated steel, which is the nearest match to the SS44B bearing type and corner style in the smaller leaf. Also at 3-1/2 inch square corner: the Emtek 91013 residential plain bearing pair, the Emtek 92013 heavy duty plain bearing pair, and the Schlage Residential S3P1010 square corner plain bearing mortise hinges in packs of three. The Orca 3514 Series is 3-1/2 inch by 3-1/2 inch with a 1/4 inch radius corner for radius-prepped frames.

The SS44B does not have a non-removable pin. Where the hinge knuckles are exposed on the outside of an outswing door and the pin has to be secured, the Hager BB1168 is a non-removable pin full mortise ball bearing hinge in heavy duty. It keeps the full mortise mounting and ball bearing action of the SS44B and adds the NRP set screw that blocks the pin from being driven out with the door closed.

SS44B is sold by the pair, so one order covers two of the three hinges a standard 6-foot-8 door carries. Buy two pairs per door and you have a spare, or plan on ordering in pairs across the opening count. Taller or heavier doors take four hinges, which is two pairs even.

Both screw types ship with the hinge: #12 x 1-1/4 inch wood screws for a wood jamb and door, and #10 x 1/2 inch machine screws for a tapped hollow metal frame. So a wood door hung in a hollow metal frame is covered without a trip to the fastener aisle. If you are going into a wood jamb on an exterior door, most installers swap at least one screw per leaf for a 3 inch to reach the framing behind the jamb.

Ball bearing is the right call anywhere the door is heavy, has a closer on it, or swings all day. The SS44B carries ball bearings between the knuckles, which cut the friction that makes a plain bearing hinge squeal and wear oval at the barrel. On a light interior passage door a plain bearing hinge is fine, and options like the Orca 4040 Series square corner plain bearing hinge or the Emtek 91013 residential plain bearing pair cover that job at the same nominal size class.

No. The SS44B is a full mortise butt hinge with square corners and matching leaves, so the same hinge works on a left hand or right hand door. You pick size, corner style, and finish, nothing else. Handing only enters the picture on spring hinges, electrified hinges, or half mortise types.

Stepping up in leaf size and weight rating: 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 heavy weight full mortise ball bearing hinges at 5 inch by 4-1/2 inch, all rated heavy duty. The Ives 3CB1HW is a steel heavy weight concealed bearing full mortise hinge with 3 knuckles, also heavy duty. All of these share the SS44B full mortise mounting method, so they hang the same way, but the larger leaf requires a wider mortise in both door and frame. The SS44B itself is characterized as residential.

No. The SS44B uses ball bearings visible between the knuckles. Concealed bearing hinges such as the Ives 3CB1 and 3CB1-B, both 3-knuckle concealed bearing full mortise hinges in medium duty, and the Hager 920 full mortise concealed bearing hinge with 2-knuckle steel construction, hide the bearing inside the barrel for a smooth uninterrupted knuckle line. Both types are full mortise like the SS44B, so the door and frame prep is the same style of pocket, but the knuckle count and barrel appearance differ, which matters when you are matching the look of hinges already hung on adjacent doors.

The SS44B is a standard full mortise ball bearing hinge and has no closing mechanism; the door stays where you leave it. 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 in heavy duty, and it carries an internal spring that returns the door to the closed position. It shares the square corner and full mortise prep style of the SS44B but in the larger 4.5 inch leaf, and spring hinges are typically installed with at least one non-spring hinge in the same opening.

The SS44B is full mortise, meaning both the door edge and the frame rabbet get a routed pocket. Where the frame cannot be routed, the Hager 1129 is a half mortise plain bearing commercial hinge in 4-1/2 inch standard weight steel, which mortises into the door but attaches to the face of the frame, and the Hager 990 STEEL is a full surface hinge at 3 inch by 4 inch with a welded tip, mounting to the face of both door and frame with no routing at all. Both are heavy duty. The tradeoff is appearance: full mortise leaves only the barrel visible, while half mortise and full surface leave a leaf on the face.

Both cover 4 inch by 4 inch exterior residential work and both come as pairs. The Deltana SS44B is a 4 inch by 4 inch square corner ball bearing hinge with a stainless steel base, which Deltana calls out for waterside properties and outdoor use for its corrosion resistance against regular steel hinges, and it comes in polished stainless and brushed stainless. The Delaney RH45xx is a 4 inch by 4 inch bulk residential exterior hinge with a 5/8 inch radius, and the Delaney RH40xx is a 4 inch by 4 inch residential hinge for Castlegate doors available 5/8 inch radius or square. For a fleet buy, the deciding factors are the corner prep already in your frames and whether the doors sit in a coastal or high-moisture environment.

The SS44B uses a stainless steel base, which Deltana positions for waterside properties and outdoor use because of its corrosion resistance compared to regular steel hinges. The other non-ferrous route is the McKinney T2314, a non-ferrous standard weight 5-knuckle hinge in medium duty. Both avoid the plain steel base that rusts in salt air; they differ in leaf construction and knuckle count, and the SS44B is the one that comes at 4 inch by 4 inch with square corners in polished or brushed stainless.

The McKinney MP79 MacPro is a 5-knuckle standard weight full mortise hinge and the MPB79 MacPro is the 5-knuckle standard weight hinge in the same family, both rated standard duty. The Stanley FBB191 is a 5-knuckle full mortise standard weight hinge at 4.5 inch by 4.5 inch in heavy duty. All are full mortise like the Deltana SS44B, so the prep style carries over, but the SS44B is characterized as residential and comes at 4 inch by 4 inch, while the Stanley FBB191 is the larger 4.5 inch leaf.

No. The SS44B is a full mortise hinge, which swings one way. For a door that has to swing both directions, the BEST DAP-3 is a heavy duty double acting pivot for commercial interior doors. It is a pivot rather than a hinge, so it mounts at the top and bottom of the door rather than in a hinge mortise along the edge, and the door and frame prep is completely different from a hinge prep.

The Deltana SS44B is sold as a pair, so a door hung on three hinges takes two pairs with one leftover, or you plan the count across a run of doors. Peers are packaged differently: the Ives 1010RP steel plain bearing residential hinges with square corners come as a set of 3, and the Schlage Residential S3P1010 square corner plain bearing mortise hinges come in a pack of 3, both of which cover a single three-hinge door in one unit. The Emtek 91013, 92013 and 94013 and the Delaney RH45xx are all sold in pairs like the SS44B.

The Ives 3CB1 is a steel 3-knuckle concealed bearing full mortise hinge with a medium duty rating, and the Ives 3CB1-B is the same 3-knuckle concealed bearing full mortise design described as medium duty commercial grade. The Deltana SS44B is a 4 inch by 4 inch square corner ball bearing hinge in stainless steel, characterized as residential and offered in polished stainless and brushed stainless. Both mount full mortise. The 3CB1 hides its bearing inside a 3-knuckle barrel on a steel base; the SS44B runs an exposed ball bearing on a stainless base intended for outdoor and waterside exposure.

Two: polished stainless and brushed stainless. Brushed is the one that lines up with satin stainless lever sets and pulls and hides fingerprints on a high-traffic entry; polished reads bright, closer to a chrome look. Both are the same stainless hinge underneath, so you can mix by opening without changing the prep.

Yes, and it is a straightforward standardization. Every SS44B is the same 4 x 4 square corner full mortise footprint in one of two stainless finishes, so once the openings are prepped to 4 x 4 square, any door in the fleet takes the same hinge and the same screws. Pick brushed or polished once and order in pairs by door count.

They are different products. The McKinney SQ3331 is a square barrel 2-knuckle decorative hinge at 4-1/2 inch by 4-1/2 inch in standard duty, chosen for the square barrel look on the door edge. The Deltana SS44B is a 4 inch by 4 inch square corner ball bearing hinge in stainless steel. The SQ3331 is a larger leaf that needs a 4-1/2 inch mortise, so it is not a drop-in for a 4 inch prep, and the two read very differently on the door edge - a square barrel versus a bearing knuckle stack.

No, those are built for a different opening entirely. The BEST BB855 is a heavy-duty steel double weight concealed ball bearing prison hinge in the detention hardware family, and the Stanley BB855 is a double weight prison hinge at 5 inch by 6 inch furnished with no holes and not swaged. Not swaged and no holes means the leaves are meant to be welded or field-drilled into a detention frame, not screwed into a wood door. The Deltana SS44B is a 4 inch by 4 inch stainless full mortise hinge that installs with #12 x 1-1/4 inch wood screws and #10 x 1/2 inch machine screws.

The BEST CB1969R is a concealed bearing heavy weight pivot-reinforced hinge rated heavy duty, built for doors heavy enough to need the pivot reinforcement at the top of the opening. The Deltana SS44B is a 4 inch by 4 inch square corner ball bearing hinge in stainless steel, full mortise, characterized as residential. The CB1969R is a different class of opening hardware and requires the pivot reinforcement prep in the frame head, which a standard 4 inch hinge pocket does not provide.
