Deltana SS45B 4-1/2" x 4-1/2" Square Hinge, Ball Bearing, Stainless Steel (Pair)

Yes. The SS45B measures 4-1/2 by 4-1/2 inches with square corners and is a full mortise hinge, so it drops into an existing square-corner mortise of that size on both the door edge and the frame. If your current mortise has rounded corners (typically a 1/4 or 5/8 inch radius), this one will leave gaps at the corners unless you square them out with a chisel.

That is the reason this one exists. The SS45B is stainless steel through the leaf, not plated steel, so it resists corrosion far better than a standard steel hinge on waterside properties and exterior openings. Plated steel hinges like the Emtek 94013 heavy duty ball bearing hinge are fine indoors but will rust at the knuckle in salt air.

The SS45B is not supplied with a non-removable pin, so for an out-swinging exterior opening where the pin is accessible from outside, look at the Hager BB1168-NRP, a non-removable pin full mortise ball bearing hinge rated heavy duty. It keeps the full mortise mounting and ball bearing action of the SS45B while adding the NRP set screw feature.

The SS45B is classified residential duty. For a commercial 4-1/2 inch by 4-1/2 inch opening, the Stanley Security FBB191 is a 5-knuckle full mortise standard weight hinge at 4.5 by 4.5 rated heavy duty, and the Ives 3CB1HW is a steel heavy weight concealed bearing full mortise hinge. Both keep the full mortise prep; the Ives uses a 3-knuckle concealed bearing instead of the exposed ball bearing knuckles of the SS45B.

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, which matches the SS45B on size, square corners, and ball bearing action. The difference is material: the SS45B is stainless steel, which Deltana positions for waterside properties and outdoor use because of its corrosion resistance compared to regular steel hinges, while the Orca 3535 is a commercial steel hinge.

No. The SS45B is a plain mechanical stainless steel hinge with no wiring provision. For power transfer through the hinge, use an energy transfer hinge such as the Command Access ETH-BB68, a 5-knuckle heavy duty steel base hinge, or the Stanley CECB1900R54L, a 4-1/2 by 4-1/2 square corner concealed conductor hinge with 4 wires. If you also need door position monitoring, the Command Access ETM-BB68 adds an integrated door position switch.

The SS45B is a standard pin hinge and will not close the door on its own. The Stanley Security 2060R in 4.5 by 4.5 is a full mortise square corner spring hinge on a ferrous steel base rated heavy duty, which provides self-closing action in the same size and corner style, so the existing square corner mortise carries over.

The SS45B is sold by the pair, so a typical exterior door hung on three hinges needs two pairs (you will have one spare leaf pair left over), and a door hung on two hinges takes a single pair. Three hinges is standard on a 6-foot-8 door at 4-1/2 inch size.

Yes, wood screws are specified with the hinge at #12 x 1-1/4 inch. For an exterior door hung on wood jambs, at least one screw per frame leaf should be swapped for a longer screw that reaches the stud behind the jamb.

No handing to call out. It is a full mortise butt hinge with square corners in a symmetrical 4-1/2 by 4-1/2 size, so the same pair works on a left or right hand door. Handing only comes into play on hinges like the Stanley CECB1900R54L electrified hinge, which is ordered left-handed.

Ball bearing, which is what the SS45B uses. The bearings carry the door weight and cut friction, so a heavy or frequently used door swings without binding and the knuckles do not wear out. Plain bearing hinges such as the Orca 4040 Series 4 by 4 square corner or the Schlage Residential S3P1010 are for lighter interior doors with less traffic.

The leaf gauge is .134 inch. That matters when you are replacing one hinge in an existing mortise, since a thicker or thinner leaf changes how the door sits against the stop and can throw off the reveal on the strike side.

No. The SS45B is a 4-1/2 inch hinge and needs a mortise of that width and height on every leaf position. If the rest of the door is hung on 4 inch hinges, either go all 4-1/2 inch and recut the mortises, or stay at 4 inch with something like the Delaney CH401X 4 by 4 ball bearing square corner hinge.

Yes. For low-traffic interior doors that do not need bearings, the Orca Hardware 4040 Series is a 4 inch by 4 inch square corner plain bearing commercial hinge in medium duty, and the Schlage Residential S3P1010 is a 3.5 by 3.5 square corner plain bearing mortise hinge sold in packs of three. Both keep the square corner prep of the SS45B but step down in size, so confirm the existing mortise before substituting.

Both are 4-1/2 inch by 4-1/2 inch. The McKinney SQ3331 is a square barrel 2-knuckle decorative hinge rated standard duty, so the barrel profile is squared off rather than the conventional round knuckle stack. The Deltana SS45B is a ball bearing hinge in stainless steel with square corners and full mortise mounting. Choose by barrel appearance and material rather than assuming they are interchangeable in look.

The SS45B is 4-1/2 inch by 4-1/2 inch and will not drop into a 4 inch mortise. The Delaney CH401X is a 4 inch by 4 inch commercial ball bearing hinge with square corners, which keeps the ball bearing action and square corner prep at the smaller size. For an exterior residential opening at 4 inch, the Delaney RH45xx is a bulk exterior residential hinge with a 5/8 inch radius corner, so verify your corner style before ordering it.

Not a direct one. The Emtek 94013 is a heavy duty ball bearing hinge pair with square corners in plated steel at 3-1/2 inch by 3-1/2 inch, while the SS45B is 4-1/2 inch by 4-1/2 inch stainless steel. Both ship as a pair with square corners and ball bearings, but the size difference means a different mortise, and the stainless body of the SS45B is what Deltana points to for waterside and outdoor exposure.

Two: polished stainless and brushed stainless. Brushed is the usual pick when it has to sit next to satin nickel or brushed chrome trim on the same door; polished matches bright chrome hardware.
