Deltana SS44 4" x 4" Square Corner Hinge, Stainless Steel (Pair)

Yes. The SS44 is a 4 inch by 4 inch full mortise hinge with square corners, so it drops into an existing square corner 4 x 4 mortise without re-routing. If the existing mortise has rounded (radius) corners, you either need to square the corners with a chisel or pick a radius corner hinge instead.

That is exactly what they are for. The SS44 is solid stainless steel, which holds up far better than plated steel against salt air and weather, so it is a common pick for waterside properties and exterior doors. Stainless also avoids the rust streaking you get when a plated steel hinge wears through in a wet location.

No. The SS44 is supplied without the NRP feature, so the pin can be driven out from the hinge side. On an out-swinging exterior door where the barrel is exposed, use a non-removable pin hinge such as the Hager BB1168 NRP, or add security studs.

The Deltana SS44 is classified for residential use. For a commercial opening at the same 4 inch by 4 inch square corner size, the Orca Hardware 4040 Series is a medium duty commercial plain bearing hinge. If the opening carries a heavier door and you want bearings, the Ives 3CB1HW is a heavy duty steel three knuckle concealed bearing full mortise hinge, and the Hager BB1168 is a heavy duty full mortise ball bearing hinge supplied with a non-removable pin.

The Deltana SS44 is a 4 inch by 4 inch square corner full mortise plain bearing hinge sold as a pair. The nearest match in size, corner style and bearing type is the Orca Hardware 4040 Series, a 4 inch by 4 inch square corner plain bearing commercial hinge rated medium duty. The Delaney CH401X is also 4 inch by 4 inch square corner but is a ball bearing hinge rather than plain bearing. The SS44 differs from both in being stainless steel throughout.

The Deltana SS44 has square corners, so it will not drop into a radiused mortise without chisel work. For a 4 inch by 4 inch opening with 1/4 inch radius corners, the Orca Hardware 4014 Series is a plain bearing commercial hinge in that exact corner profile. Delaney's 4 inch by 4 inch exterior residential hinge pair, the RH45xx, uses a 5/8 inch radius, and the RH35xx is the same 5/8 inch radius profile at 3-1/2 inch for interior doors.

The SS44 4 x 4 is sold by the pair, two hinges per unit. Most interior and standard exterior doors take three hinges, so a single door usually needs two pairs with one hinge left over, or order accordingly if you are hanging several doors.

Screws are specified with the hinge: #12 x 1-1/4 inch wood screws for wood jambs and doors, and #10 x 1/2 inch machine screws for metal frames. The machine screws only work if your frame is already tapped for them.

No. The SS44 is a plain mechanical hinge with no wire path through the barrel. To transfer power through the hinge you need an electrified hinge such as the Command Access ETH-CB70 standard weight or ETH-BB68 heavy duty, or the BEST CECB179-12C with a 12-wire quick connect. If you also need door position monitoring, the Command Access ETM-CB70 or ETM-BB68 add an integrated position switch.

The SS44 is stainless steel, which Deltana positions for waterside properties and outdoor use because of its corrosion resistance compared with regular steel hinges. On a dry interior opening that resistance is not needed. The Emtek 91013 is a residential duty plated steel plain bearing pair with square corners, and the Ives 1010RP is a steel plain bearing residential square corner hinge sold in sets of three. Both are steel rather than stainless and both are 3-1/2 inch rather than 4 inch, so confirm your mortise size.

Not automatically. The Deltana SS44 uses a plain bearing. A ball bearing hinge of the same 4 inch by 4 inch square corner size, such as the Delaney CH401X commercial ball bearing hinge, will mortise the same way but carries a bearing race between the knuckles, which changes the knuckle appearance. At a larger leaf size the Orca 3535 Series is a 4-1/2 inch by 4-1/2 inch square corner ball bearing commercial hinge and would require a wider mortise.

Several hinges in the same family serve very different openings. The Hager 1129 is a half mortise hinge, so only one leaf mortises into the door. The Hager 990 STEEL is a full surface prison hinge with a welded tip. The BEST DAP-3 is a double acting pivot, not a butt hinge at all. The Stanley 2060R is a spring hinge for self-closing service, and the Command Access ETH-CB70 and ETM-CB70 are energy transfer hinges that pass wiring through the door. The Deltana SS44 is a plain full mortise butt hinge with a removable pin.

The Deltana SS44 is stainless steel and Deltana calls it out for waterside properties and outdoor use. The McKinney T2314 is a non ferrous standard weight five knuckle hinge, which is the other route to corrosion resistance in the same full mortise butt hinge format. The T2314 is rated medium duty. Match leaf size to your existing mortise before switching, since the SS44 is 4 inch by 4 inch.

The Deltana SS44 is 4 inch by 4 inch. Stepping up to 4-1/2 inch by 4-1/2 inch, the Orca 3535 Series is a square corner ball bearing commercial hinge, the Stanley FBB191 is a five knuckle full mortise standard weight hinge at that size, and the McKinney SQ3331 is a 4-1/2 inch by 4-1/2 inch square barrel two knuckle decorative hinge. A 4-1/2 inch leaf needs a deeper and longer mortise than the SS44.
