Deltana SS44R5B-RN 4" x 4" x 5/8" Radius Corner Hinge, Residential, NRP, Stainless Steel (Pair)

Yes, if the existing mortise is 4 x 4 with 5/8 inch radius corners. The SS44R5-RN is a full mortise hinge measuring 4 inches by 4 inches with 5/8 inch radius corners, which is the standard router-cut corner on most residential prehung doors and jambs. If your existing mortise has square corners, you need a square corner hinge instead, or you will have gaps at the four corners of the leaf.

NRP is a non-removable pin. On an outswing exterior door the hinge barrel sits on the outside, so without NRP somebody could drive the pin out and lift the door off. The SS44R5-RN ships with the pin non-removable, which closes that off. On an inswing door with the barrel inside, NRP does not hurt, it just means you cannot pull the pin to take the door off, you unscrew the leaf instead.

The SS44R5-RN is a plain bearing hinge, which is the normal choice for residential interior and exterior doors that are not under a closer and not seeing constant traffic. Put a ball bearing hinge on the opening instead if the door carries a closer, is unusually heavy, or gets commercial-level cycles. For that, the Orca Hardware 3535 Series 4-1/2 x 4-1/2 square corner ball bearing hinge or the Delaney CH401X 4 x 4 commercial ball bearing hinge are the ball bearing route.

The Deltana SS44R5-RN is a residential-duty plain bearing hinge. For commercial traffic at the same 4 inch by 4 inch size, the Orca Hardware 4014 Series is a 4 inch by 4 inch commercial plain bearing hinge with 1/4 inch radius corners, and the Orca 4040 Series is the square corner version, both rated medium duty. Note the corner change: the Deltana uses 5/8 inch radius corners, so an Orca 1/4 inch radius or square corner hinge will not match an existing 5/8 inch radius mortise without rework. Delaney also offers a 4 inch by 4 inch commercial ball bearing hinge with square corners.

The Delaney RH45xx is the nearest match in shape and size: it is a 4 inch by 4 inch residential hinge with 5/8 inch radius corners sold as a pair, the same 4 inch by 4 inch size and 5/8 inch radius corner profile the Deltana SS44R5-RN uses, so it drops into an existing 5/8 inch radius mortise without rerouting. The difference is material and pin: the Deltana SS44R5-RN is stainless steel with a non-removable pin, which is what you want on an out-swinging exterior door or a coastal opening.

The Deltana SS44R5-RN carries a non-removable pin and is a residential-duty plain bearing hinge in stainless steel. If the opening is commercial and heavy, the Hager BB1168-NRP is a full mortise ball bearing hinge with a non-removable pin rated heavy duty. Both block pin removal from the hinge side; the Hager adds ball bearings and heavy duty construction, while the Deltana gives you a stainless base for corrosion resistance on waterside and outdoor openings.

That is the reason this one exists. The SS44 hinge is stainless steel through the leaf and substrate, not plated steel, so it holds up in salt air and wet exposure far better than a plated steel hinge, which rusts from the edges and screw holes once the plating is scratched. For waterside properties and any outdoor opening, that is the trade-off you are paying for.

Sold as a pair. A standard residential door normally takes three hinges, so for one full door you would order two pairs and have a spare leaf set, or plan the quantity around three per opening.

Wood screws are included, #10 x 1 inch. No machine screws are supplied, so this is set up for wood door and wood jamb work rather than hollow metal frames. If you are hanging a heavy slab or a door that has been rehung before, longer screws into the jamb stud are a common upgrade, but they are not part of the pack.

The SS44 hinge is a 4 x 4 only. For 3-1/2 inch residential openings, ZenSupply carries the Delaney RH35xx 3-1/2 x 3-1/2 steel residential hinge with 5/8 inch radius corners, which matches the same corner radius, plus the Emtek 91013 residential plain bearing pair and the Schlage Residential S3P1010, both 3-1/2 inch square corner. Note those are plated or steel base rather than stainless, so they are not a like-for-like swap on a salt-air exterior door.

For exterior wood doors on residential units it lines up well: 4 x 4 full mortise with 5/8 inch radius corners is the size and corner most prehung residential doors are already routed for, stainless handles weather without rusting at the screw holes, and the non-removable pin removes the lift-off attack on outswing doors. Where it stops being the right call is any door hung with a closer or seeing corridor-level traffic, since this is a residential-duty plain bearing hinge. Those openings want a commercial ball bearing hinge such as the Delaney CH401X 4 x 4.

For an interior door, the Delaney RH35xx is a bulk steel residential interior hinge with 5/8 inch radius corners sold in pairs, in a 3-1/2 inch by 3-1/2 inch size. Confirm your mortise: the Deltana SS44R5-RN is 4 inch by 4 inch, so the 3-1/2 inch Delaney is not a drop-in for a 4 inch cutout. Delaney also lists a 4 inch by 4 inch residential hinge for Castlegate doors with a 5/8 inch radius by square profile if you need to stay at 4 inches.

For a self-closing opening, the Stanley Security 2060R is a full mortise spring hinge in 4-1/2 inch by 4-1/2 inch with square corners on a ferrous steel base, rated heavy duty; the Deltana SS44R5-RN has no spring and is a 4 inch by 4 inch plain bearing hinge. If you only need the larger 4-1/2 inch leaf without a spring, the Stanley FBB191 is a 5-knuckle full mortise standard weight hinge in 4-1/2 inch by 4-1/2 inch. Both are square corner, so verify the frame prep before ordering.

The Deltana SS44R5-RN is sold as a pair, so a three-hinge door takes two packs plus a spare. If you prefer a three-per-door pack, the Ives 1010RP is a steel plain bearing residential hinge sold as a set of three with square corners, and the Schlage Residential S3P1010 is a 3-1/2 inch by 3-1/2 inch square corner plain bearing mortise hinge in a pack of three. Both are square corner and smaller than the Deltana's 4 inch by 4 inch with 5/8 inch radius corners, so match them to the existing door mortise before you standardize.

Leaf thickness is .085 inch, and the screw holes are laid out in an arc pattern, which is the usual staggered layout on residential hinges so the screws do not all land in the same grain line. Because the leaf gauge and the 4 x 4 size are standard, the mortise depth cut for a typical residential 4 inch hinge takes it without re-routing.

Brushed Stainless is the finish offered on the SS44R5-RN, which is the satin stainless look that reads close to satin nickel or brushed chrome trim on the same door without being plated.
