Deltana SS44N 4" x 4" Square Corner Hinge, NRP, Stainless Steel (Pair)

NRP stands for non-removable pin, and the SS44N is built with one. On an out-swing door the hinge barrel sits on the outside, so a plain hinge can be defeated by driving the pin out and lifting the door off. The non-removable pin blocks that. It's the reason to pick this over a standard-pin hinge on any exterior or otherwise exposed opening.

The SS44N measures 4 x 4 inches with square corners and mortises into both the door edge and the frame. If your current hinges are 4 x 4 square corner, it drops straight into the existing pockets. If your pockets have rounded corners (a 5/8 inch or 1/4 inch radius, cut by a router template), the square leaf will not seat, and you'd either square the corners with a chisel or buy a radius corner hinge instead.

That is the case for this one. The SS44N is stainless steel through the body, not plated steel, so it resists the corrosion that eats plated hinges in salt air. On waterfront and other exposed openings, plated residential hinges rust at the knuckle and stain the door face within a season or two. If the opening is interior and dry, a plated steel hinge such as the Emtek 91013 covers it for less material.

Each pair ships with both fastener types: #12 x 1-1/4 inch wood screws for a wood jamb and door, and #10 x 1/2 inch machine screws for a metal frame with tapped hinge preps. Nothing else is required for the mount itself. Note the unit of measure is a pair, so a standard three-hinge door needs two pairs ordered, leaving one spare hinge.

Plain bearing is what the SS44N uses, and it's rated residential. That suits a house entry, patio door, or low-traffic opening where the door swings a handful of times a day. Once a door sees constant cycling, carries a closer, or hangs heavy (solid core, glass, storefront), the bearing surface wears and the door starts to sag, which is why commercial openings use bearing hinges. For that duty look at a ball bearing unit like the Orca 3535 Series 4-1/2 x 4-1/2 square corner or the Delaney CH401X 4 x 4 commercial ball bearing hinge.

No, look elsewhere for that opening. The SS44N is a residential-duty plain bearing hinge; a commercial door with a closer needs a heavy duty bearing hinge. The Hager BB1168 is a heavy duty full mortise ball bearing hinge supplied with a non-removable pin, which is the direct commercial counterpart for the security-pin requirement.

The Orca Hardware 4040 Series is a 4 inch by 4 inch square corner plain bearing commercial hinge, matching the SS44N on size, square corner style and plain bearing action. The SS44N is stainless steel with a non-removable pin; the Orca 4040 is a medium duty commercial hinge. If the opening is a coastal or exterior door, the stainless base of the SS44N is the reason to stay with it.

The Orca Hardware 4014 Series is a 4 inch by 4 inch plain bearing commercial hinge with 1/4 inch radius corners, medium duty. The Deltana SS44N is cut with square corners, so it needs a square mortise or a squared-off prep. Confirm the existing mortise corner before ordering either one, since a square hinge in a radius mortise leaves a gap at each corner.

The Hager BB1168 is a non-removable pin full mortise ball bearing hinge rated heavy duty. The Deltana SS44N is also non-removable pin and full mortise, but it is a residential-duty plain bearing hinge in stainless steel. For a high-traffic or heavy commercial leaf, the BB1168 ball bearing heavy duty construction is the one to spec; the SS44N suits residential and waterside openings where corrosion resistance is the driver.

The Emtek 91013 is a residential plain bearing hinge pair, 3-1/2 inch by 3-1/2 inch with square corners in plated steel, and the Schlage Residential S3P1010 is a 3-1/2 inch by 3-1/2 inch square corner plain bearing mortise hinge supplied in packs of three. The Deltana SS44N is a 4 inch by 4 inch hinge and will not drop into a 3-1/2 inch mortise without recutting the jamb and door edge.

The Don-Jo HWBB84545 is a heavy weight full mortise ball bearing hinge, 4-1/2 inch by 4-1/2 inch in satin chrome, rated heavy duty, and the Orca 3535 Series is a 4-1/2 inch by 4-1/2 inch square corner ball bearing commercial hinge at medium duty. Both step up from the 4 inch by 4 inch residential-duty SS44N in both leaf size and bearing type. Moving from 4 inch to 4-1/2 inch means a wider mortise on both the door edge and the jamb.

No handing to specify. The SS44N is a symmetrical full mortise butt hinge with square corners on both leaves, so the same hinge works on a left or right hand door; you just orient it when you hang it. Handing only becomes an ordering question on hinges with an asymmetric feature, the way the Stanley CECB1900R54L electrified hinge is sold left-handed because of where its wire exits.

The SS44 hinges are packaged and sold by the pair, so the smallest quantity is two hinges. For a single-hinge swap that leaves you a spare, which is generally worth having on a coastal door. Be aware of mixing: a new brushed stainless leaf next to two weathered plated hinges will not match visually, and if the old ones are corroding the other two are usually next. Most people change all three at once.

Not without cutting. Going from 3-1/2 to 4 inches means deepening and lengthening every mortise in the door edge and jamb, and the existing screw holes won't line up. The 4 x 4 size on the SS44N suits a heavier or thicker exterior door; if you're matching what's already hung, stay at 3-1/2 x 3-1/2 with something like the Emtek 91013 square corner residential pair or the Schlage S3P1010 3.5 inch square corner set.

Yes for the exterior openings, and it's a reasonable single spec if you want one hinge on the truck. The 4 x 4 square corner size and residential plain bearing build cover typical entry and patio doors, the stainless handles weather, and the non-removable pin means the out-swing units get the same security as the in-swing ones without a second part number. The catch is mortise size: interior doors in most units are hung on 3-1/2 inch hinges, so those openings would need chisel work to take a 4 inch leaf.

A door under a closer cycles constantly, and ball bearing hinges are built for that duty. In a 4 inch square corner size, the Delaney CH401X is a 4 inch by 4 inch commercial ball bearing hinge with square corners. The Deltana SS44N is a plain bearing hinge, which relies on knuckle-to-knuckle contact rather than bearings between the knuckles. Both take the same 4 inch square mortise.

Both are sold as pairs and both are residential exterior hinges in a 4 inch by 4 inch size. The Delaney RH45xx exterior residential hinge has 5/8 inch radius corners; the Deltana SS44N has square corners, a stainless steel base and a non-removable pin. Match the corner style to the existing mortises across the units, and use the stainless SS44N where salt air or standing moisture is the concern.

No. The Command Access ETH-CB70 is an energy transfer hinge with a 3 knuckle standard weight steel base, built to carry power through the hinge to an electrified lock or strike. The Deltana SS44N is a plain mechanical hinge with no wire path. An electrified opening still needs standard hinges on the remaining knuckle positions, so the SS44N or a like hinge can hang alongside a transfer hinge rather than in place of it.

No. The Stanley Security 2060R is a full mortise spring hinge in a 4.5 inch by 4.5 inch square corner size with a ferrous steel base, rated heavy duty, and it carries the spring that pulls the door shut. The Deltana SS44N is a plain bearing hinge with no closing mechanism, so a door hung on it stays where it is left. Note the 2060R is a 4-1/2 inch hinge against the 4 inch SS44N, so the mortise depth and jamb prep differ.

The Ives 1010RP is a steel plain bearing residential hinge with square corners, medium duty, sold as a set of three. It shares the plain bearing action and square corner style with the Deltana SS44N, which comes as a pair in stainless steel with a non-removable pin. Count the quantity carefully when ordering, since one is a set of three and the other is a pair, and use the stainless SS44N on exterior and waterside openings.

No. Detention openings call for purpose-built hardware: the BEST BB855 is a heavy-duty steel double weight concealed ball bearing prison hinge, and the Hager 990 STEEL is a full surface prison hinge, 3 inch by 4 inch, with a welded tip and heavy duty rating. The Deltana SS44N non-removable pin feature keeps the pin from being driven out on an out-swing door, which is a residential and light commercial security measure, not a detention-grade one.

No. The Deltana SS44N is a full mortise hinge, meaning both leaves mortise into the door edge and the jamb. For a half mortise condition, the Hager 1129 is a half mortise plain bearing commercial hinge in a 4-1/2 inch standard weight steel build, rated heavy duty, where one leaf surface-mounts instead. Verify which leaf the frame is prepped for before ordering.

Brushed stainless, and that's the only finish the SS44N is offered in. It's the natural finish of the stainless itself rather than a plating, which is part of why it holds up outdoors: there's no coating to chip or wear through at the knuckle and expose bare steel underneath.

Both are full mortise hinges, but they are built differently. The Hager 920 is a full mortise concealed plain bearing hinge with 2 knuckle steel construction, rated medium duty, so the bearing is hidden inside the barrel. The Deltana SS44N is a stainless steel plain bearing hinge with a non-removable pin and square corners. Choose the SS44N when the pin must not be pulled from the hinge side and when corrosion resistance matters.
