Deltana SS33-R 3" x 3" Square Hinge, Residential, Stainless Steel (Pair)

That's what the SS33-R is built for. It's stainless steel through the leaves and the pin, so it resists corrosion far better than a plated steel hinge on salt air or damp exterior openings. Deltana calls it out specifically for waterside properties and outdoor use. Note the duty level though: it's a residential hinge with a plain bearing, so it suits house and light-traffic doors, not a commercial entry cycling all day.

Yes, and that matters. The SS33-R is not a non-removable pin hinge, so on an outswing door the knuckles are on the exterior side and the pin can be driven out. For an outswing entry where security is a concern, use a hinge with an NRP feature, such as the Hager BB1168 NRP full mortise ball bearing hinge.

The Deltana SS33-R is a plain bearing, square corner, full mortise residential hinge sold as a pair in stainless steel. The closest plated steel counterpart is the Emtek 91013, a residential plain bearing hinge pair with square corners in plated steel. The difference that matters is the base material and the leaf size: the SS33-R measures 3 inches by 3 inches, while the Emtek 91013 is 3-1/2 inches by 3-1/2 inches, so the mortise and screw pattern in the jamb will not line up between the two.

The Deltana SS33-R is rated residential and uses a plain bearing, which suits standard interior and light exterior slabs. For a heavier door, step up to a ball bearing or heavy duty leaf: the Emtek 94013 is a heavy duty ball bearing hinge pair, 3-1/2 inches by 3-1/2 inches with square corners in plated steel, and the Emtek 92013 is a heavy duty plain bearing pair in the same 3-1/2 inch square corner format if you want to keep the plain bearing knuckle. Both are larger leaves than the SS33-R's 3 inch by 3 inch, so plan on recutting the mortise.

The SS33-R is a residential grade hinge. On the commercial side with square corners, the Orca Hardware 4040 Series is a 4 inch by 4 inch square corner plain bearing commercial hinge at medium duty, and the Orca Hardware 3535 Series is a 4-1/2 inch by 4-1/2 inch square corner ball bearing commercial hinge, also medium duty. The Delaney CH401X is a 4 inch by 4 inch commercial ball bearing hinge with a square corner. All three use larger leaves than the SS33-R's 3 inch by 3 inch size.

No. The SS33-R has square corners, which means it drops into a mortise routed with a chisel or a square-corner template. If the doors were machined with a radius router bit, you want a radius-corner leaf instead: the Delaney RH35xx is a 3-1/2 inch by 3-1/2 inch residential interior hinge pair with a 5/8 inch radius, the Delaney RH45xx is a 4 inch by 4 inch bulk residential exterior hinge pair with a 5/8 inch radius, and the Orca 3514 Series is a 3.5 inch by 3.5 inch plain bearing commercial hinge with a 1/4 inch radius corner. Match the radius to what is already cut in the door.

The SS33-R is not a non-removable pin hinge. If the opening swings out and the barrel is exposed, specify a hinge built for it: the Hager BB1168 is a non-removable pin full mortise ball bearing heavy duty hinge. That is a heavy duty commercial leaf rather than a 3 inch by 3 inch residential one, so confirm the mortise size on the door before ordering.

Yes. The SS33-R is stainless steel throughout, which Deltana positions for waterside properties and outdoor use because of its corrosion resistance compared to regular steel hinges. The common residential alternatives are steel-based: the Emtek 91013 is plated steel, the Delaney RH45xx exterior residential hinge is a bulk residential steel-format hinge, and the Ives 1010RP is steel. If salt air is the concern, the stainless base material is the distinguishing factor.

The SS33-R is sold as a pair, two hinges. Interior doors of this size usually take three hinges per leaf, so for a three-hinge door you'd order two pairs and have one spare, or buy in pairs per door as your opening requires.

Yes, the SS33-R ships with #9 x 3/4 inch wood screws. Those bite into a wood jamb and a wood door edge. If you're hanging on a hollow metal frame or need to reach the stud behind a split jamb, source longer or machine screws separately.

The SS33-R uses a plain bearing, which is the standard choice for residential doors that aren't especially heavy and don't cycle constantly. If you're hanging a heavy solid core or exterior slab, or an opening with a door closer on it, step up to a ball bearing hinge. The Emtek 94013 heavy duty ball bearing hinge in 3-1/2 by 3-1/2 with square corners is the residential-scale option, and the Orca Hardware 3535 Series 4-1/2 by 4-1/2 square corner ball bearing hinge covers commercial openings.

3 by 3 inch hinges suit lighter interior and cabinet-scale doors. For a standard 1-3/8 inch interior passage door, 3-1/2 by 3-1/2 is the usual size: the Emtek 91013 residential plain bearing pair and the Schlage Residential S3P1010 3-1/2 by 3-1/2 square corner plain bearing hinges both fit that prep. For a 1-3/4 inch exterior slab, go to 4 by 4, such as the Delaney RH45xx exterior residential hinges.

The SS33-R is sold as a pair, so a three-hinge door takes two orders or a pair plus a single. If you would rather buy a full door's worth in one line, the Ives 1010RP is a steel plain bearing residential hinge with square corners sold as a set of three, and the Schlage Residential S3P1010 is a 3.5 inch by 3.5 inch square corner plain bearing mortise hinge sold in a pack of three. Note both of those are 3-1/2 inch leaves where the SS33-R is 3 inch by 3 inch.

No - those solve a different problem. The SS33-R is a plain mechanical residential hinge with no electrical provision. The Command Access ETH-CB70 is an energy transfer hinge that carries power through the door, and the ETM-CB70 adds integrated door position sensing. The BEST CECB179-12C is a full mortise concealed bearing electrified hinge with a 12-wire quick connect. Use those only when an electrified lock or monitored opening requires power transfer; for a standard residential door they are unnecessary and use commercial-size leaves.

The SS33-R is a standard full mortise hinge with a plain bearing and does not provide any closing force. For a self-closing opening, the Stanley Security 2060R is a full mortise spring hinge with square corners, 4.5 inch by 4.5 inch, on a ferrous steel base at heavy duty. The square corner matches the SS33-R's corner style, but the 4.5 inch leaf means a larger mortise than the 3 inch by 3 inch SS33-R.

The SS33-R is a full mortise hinge, meaning both leaves mortise into the door and the frame. When the frame cannot be mortised, the Hager 1129 is a half mortise plain bearing commercial hinge, 4-1/2 inch standard weight steel, and the Hager 990 STEEL is a full surface prison hinge, 3 inch by 4 inch with a welded tip at heavy duty. Both are commercial products and will look and mount differently from a residential full mortise leaf.

The SS33-R uses a plain bearing knuckle. For higher cycle counts, concealed bearing hinges carry the load on bearings hidden inside the barrel: the Ives 3CB1 is a steel 3-knuckle concealed bearing full mortise hinge at medium duty, the 3CB1HW is the heavy weight version of the same 3-knuckle concealed bearing full mortise design, and the Hager 920 is a full mortise concealed plain bearing hinge with 2-knuckle steel construction at medium duty. All are commercial-format hinges rather than residential.

Brushed stainless is the finish offered on the SS33-R. It reads as a satin silver and pairs with brushed or satin nickel and satin chrome trim on the same opening without looking off.

The leaf is .085 inch thick. As a full mortise butt hinge with a removable pin, it's non-handed, so the same hinge works on a left hand or right hand door. The screw holes follow an arc pattern in the leaf.

Not a drop-in. The McKinney MP79 MacPro is a 5-knuckle standard weight full mortise hinge and the MPB79 MacPro is a 5-knuckle standard weight hinge, both standard duty commercial products. The SS33-R is a residential plain bearing pair at 3 inches by 3 inches in stainless steel. They share full mortise installation, but the sizing and duty classification are different families, so verify leaf size against the existing mortise before treating one as a replacement for the other.
