Deltana SS35R4 3-1/2" x 3-1/2" x 1/4" Radius Hinge, Stainless Steel (Pair)

Yes, if that prep is cut for a 1/4 inch radius corner. The SS35R4 measures 3-1/2 by 3-1/2 inches with 1/4 inch radius corners, which is the common factory prep on residential and light commercial wood doors and frames. If your existing mortise has square corners or 5/8 inch radius corners, this one will not seat cleanly without rework.

That is the reason to pick this one. Deltana's stainless steel hinges are built for waterside properties and outdoor openings, and they hold up against corrosion far better than plated steel hinges. On a beachfront building or a pool house door, plated steel pins and leaves rust at the knuckle first; stainless avoids that.

It ships as a pair, and the wood screws are included: #9 x 1 inch. Most 3-1/2 inch interior or light exterior doors take three hinges, so one pair plus a single leaf, or two pairs, covers a typical door. The leaf thickness is .085.

Not on its own. The SS35R4 does not have a non-removable pin, so on an outswing door the pin sits on the exposed side and can be driven out. For that opening, look at a hinge supplied NRP, such as the Hager BB1168 non-removable pin full mortise ball bearing hinge, or add set screw security studs.

No. A 3-1/2 by 3-1/2 hinge leaves a gap in a 4 inch mortise and the screw holes will not line up. Stay with a 4 inch hinge, the Orca Hardware 4014 Series is a 4 by 4 inch plain bearing commercial hinge with the same 1/4 inch radius corners.

The Orca Hardware 3514 Series is the closest match in size and corner profile: it is a 3.5 inch by 3.5 inch plain bearing commercial hinge with 1/4 inch radius corners, the same dimension, bearing type and corner style as the SS35R4. The difference is material - the SS35R4 is stainless steel, which is why it is specified for waterside properties and outdoor openings, while the Orca 3514 is rated medium duty and carried as a standard commercial hinge.

Step up to the Orca Hardware 4014 Series, a 4 inch by 4 inch plain bearing commercial hinge with 1/4 inch radius corners. It keeps the plain bearing and the 1/4 inch radius corner prep of the Deltana SS35R4 and only changes the leaf size, so it drops into a door and frame already routed for a 4 inch radius hinge. If the frame is square cut rather than radiused, the Orca 4040 Series is the 4 inch by 4 inch square corner plain bearing version.

Not without changing the mortise. The SS35R4 has 1/4 inch radius corners, while the Emtek 91013 is a 3-1/2 inch by 3-1/2 inch plain bearing hinge with square corners, as is the Schlage Residential S3P1010 at the same size. A radius mortise will leave gaps at the corners of a square leaf, and a square mortise will show rounded voids behind a radius leaf. Match the corner profile to what is already routed in the door, or plan to re-cut it.

The SS35R4 is not a non-removable pin hinge, so on an outswing door where the barrel is on the exterior it leaves the pin accessible. The Hager BB1168-NRP is a non-removable pin full mortise ball bearing hinge rated heavy duty and is the direct answer for that condition. Note it is a different size class and a ball bearing rather than the plain bearing used on the SS35R4, so confirm the mortise before you order.

Deltana classifies the SS35 Series as commercial. It is a full mortise hinge, meaning both leaves mortise into the door edge and the frame rabbet, which is the standard architectural mounting. For straight residential interior work in the same size, the Delaney RH35 bulk steel interior pair or the Emtek 91013 residential pair are the lighter options.

No handing to specify. The SS35R4 is a full mortise butt hinge with a removable pin, so the same pair works on a left or right hand door, you just orient it so the pin drops in from the top.

The Deltana SS35R4 uses a plain bearing. For openings that cycle harder, the Emtek 94013 is a heavy duty ball bearing hinge in the same 3-1/2 inch by 3-1/2 inch size, though with square corners rather than radius. In 4-1/2 inch, the Orca Hardware 3535 Series is a square corner ball bearing commercial hinge. Ball bearing hinges add bearings between the knuckles to carry the load; plain bearing hinges like the SS35R4 run metal to metal.

No. The SS35R4 is a plain bearing full mortise hinge with no electrical provision. For a powered opening, the Command Access ETH-CB70 is a 3 knuckle standard weight steel base energy transfer hinge, and the ETH-BB68 is the 5 knuckle heavy duty version. If you also need door position monitoring, the Command Access ETM-CB70 senses door position on a 3 knuckle steel base and the ETM-BB68 adds an integrated door position switch on a heavy duty body.

The SS35R4 mounts full mortise, meaning both leaves are let into the door and the frame. If only the door is mortised and the frame leaf has to surface apply, the Hager 1129 is a half mortise plain bearing commercial hinge in 4-1/2 inch standard weight steel. If neither leaf can be mortised, the Hager 990 STEEL is a full surface hinge at 3 inch by 4 inch with a welded tip. Both are steel rather than the stainless base of the SS35R4.

The SS35R4 is sold by the pair. If you would rather buy by the door leaf, the Ives 1010RP is a steel plain bearing 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 in a pack of three. Both are square corner, so they will not drop into a mortise cut for the 1/4 inch radius corners of the SS35R4.

The SS35R4 is a plain bearing hinge with no closing mechanism, so the door needs a separate closer. If you want the closing force built into the hinge, the Stanley Security 2060R is a full mortise spring hinge with square corners at 4-1/2 inch by 4-1/2 inch on a ferrous steel base, rated heavy duty. It is a larger leaf and a square corner, so the door and frame prep will differ from the 3-1/2 inch radius corner cut the SS35R4 uses.

No. The SS35R4 is a standard full mortise commercial hinge with a removable pin and no security features. For detention work, the BEST BB855 is a heavy duty steel double weight concealed ball bearing prison hinge in the Detention Hardware series, and the Stanley Security BB855 is a 5 inch by 6 inch double weight prison hinge furnished with no holes and not swaged. For anti-ligature egress applications the BEST DAP-3 is a heavy duty double acting pivot from the Emergency Rescue Hardware series.

Both address corrosion, by different means. The SS35R4 uses a stainless steel base, which the maker cites as having excellent corrosion resistance compared to regular steel hinges and suited to waterside properties and outdoor use. The McKinney T2314 is a non ferrous hinge, standard weight, 5 knuckle, medium duty. Choose based on the finish and size you need to match on the rest of the openings.

It is offered in Paint Black over the stainless steel base. If you are matching other openings in a building that already run a bright or satin stainless look, this one will read as black instead.

Yes. Concealed bearing hinges hide the bearings inside the knuckle for a smooth barrel line. The Ives 3CB1 is a 3 knuckle concealed bearing full mortise hinge rated medium duty, and the 3CB1HW is the heavy weight steel version with the same 3 knuckle concealed bearing arrangement. The Hager 920 is a 2 knuckle full mortise concealed bearing hinge in steel, medium duty. All three differ from the SS35R4, which uses a plain bearing in a stainless steel body.
