Deltana S44-RS 4" x 4" Square Hinge, Residential Thickness, Security, Steel (Pair)

The S44-RS carries a security or locking tab option, which is an interlocking stud on one leaf that seats into a hole on the other when the door is closed. If someone pulls the pin on an outswing door, the leaves stay mechanically engaged and the door cannot be lifted off. Note this is the tab approach, not a non-removable pin setscrew, since the S44-RS is not an NRP hinge.

Yes, if the existing cutout is a 4 by 4 square corner full mortise pocket. The S44-RS measures 4 inches by 4 inches with square corners and mounts full mortise, so it sits in the same prep. It will not work in a radius corner prep without rerouting the corners, and the screw holes are an arc pattern so old screw locations may not line up exactly.

No. The S44-RS is a residential thickness steel hinge at .085 leaf gauge with a plain bearing, meant for indoor residential doors. High-cycle commercial or multi-family corridor openings want a bearing hinge instead, such as the Orca Hardware 4040 Series 4 x 4 square corner plain bearing commercial hinge or the Delaney CH401X 4 x 4 commercial ball bearing square corner hinge.

Not without recutting. The S44-RS is a 4 by 4 hinge and a 3-1/2 inch mortise is both shorter and shallower in backset. If you want to keep the existing prep, stay at 3-1/2 inches with something like the Emtek 91013 or the Schlage Residential S3P1010 3.5 by 3.5 square corner plain bearing mortise hinges.

The Deltana S44-RS is a 4 inch by 4 inch square corner, plain bearing, full mortise steel hinge sold as a pair for residential use. The closest same-size equivalent is the Orca Hardware 4040 Series 4 inch by 4 inch square corner plain bearing hinge, which matches the size, square corner and plain bearing action but is rated medium duty for commercial openings. Delaney also offers a 4 inch by 4 inch residential hinge pair in the Castlegate series with one 5/8 inch radius leaf and one square leaf, so check the corner prep in your existing jamb mortise before ordering that one.

The S44-RS has square corners, so it will not drop into a mortise routed for a radius corner without rework. For a 4 inch by 4 inch opening with radius prep, the Orca Hardware 4014 Series is a 4 inch by 4 inch plain bearing hinge with 1/4 inch radius corners. If the opening is 3-1/2 inch, the Orca 3514 Series is the same plain bearing style in 3.5 inch by 3.5 inch with a 1/4 inch radius corner.

The S44-RS is only a 4 inch by 4 inch hinge, so a 3-1/2 inch mortise needs a different part. Emtek 91013 is a residential duty plain bearing hinge pair, 3-1/2 inch by 3-1/2 inch with square corners in plated steel, which is the nearest match in style and duty. Schlage Residential S3P1010 is a 3-1/2 inch by 3-1/2 inch square corner plain bearing mortise hinge sold three to a pack, and Delaney's RH35xx is a 3-1/2 inch bulk interior residential pair with a 5/8 inch radius corner if your prep is radius.

The S44-RS is a residential thickness plain bearing hinge at .085 material thickness, intended for indoor residential use. For a busier opening, a bearing hinge carries the cycle load better: the Ives 3CB1 is a medium duty three knuckle concealed bearing full mortise steel hinge, the Ives 3CB1HW is the heavy weight version of that concealed bearing hinge, and Delaney's CH401X is a 4 inch by 4 inch commercial ball bearing hinge with square corners that keeps the same size and corner style as the S44-RS.

No. The S44-RS carries a security or interlocking tab option and is listed as not having a non-removable pin, so the pin can still be driven out; the tab is what keeps the leaves engaged if that happens. If your spec calls for a set screw in the barrel that locks the pin in place, the Hager BB1168-NRP is a full mortise ball bearing heavy duty hinge supplied with a non-removable pin.

The S44-RS is sold as a pair, two hinges. A standard interior door typically hangs on three hinges, so plan on two pairs per opening and a spare leaf, or order in pairs and combine.

Full mortise butt hinges like the S44-RS are non-handed. The same hinge works on a left or right hand door, you just flip it. Mounting screws ship with Deltana hinges in the box; no separate template is required since the arc hole pattern matches standard steel butt hinge prep.

Mechanically they are the same residential steel butt hinge, 4 by 4, square corner, plain bearing, .085 thick. The S44-RS adds the security tab so the door cannot be lifted off if the pin is removed. That matters on any outswing door where the barrel is on the exterior side. On an inswing interior door the tab buys you nothing, and a plain residential hinge like the Emtek 91013 plain bearing pair covers it.

No. The S44-RS is a plain mechanical full mortise hinge with no wiring path. For power transfer through the hinge, the Command Access ETH-CB70 is a three knuckle standard weight steel base energy transfer hinge in medium duty, and the ETH-BB68 is the five knuckle heavy duty version. If you also need door position monitoring, the Command Access ETM-CB70 adds door position sensing on a three knuckle steel base, and the BEST CECB179-12C is a steel full mortise concealed bearing electrified hinge with a 12-wire quick connect.

Not dimensionally. Both are plain bearing steel hinge pairs with square corners, but the Emtek 92013 is 3-1/2 inch by 3-1/2 inch in plated steel from the heavy duty plain bearing line, while the S44-RS is 4 inch by 4 inch at residential thickness with a security tab. The 92013 will not fill a 4 inch mortise, and it does not carry the S44-RS security tab feature.

The S44-RS is a 4 inch by 4 inch hinge and will leave a gap in a 4-1/2 inch mortise. For that prep with square corners, the Orca Hardware 3535 Series is a 4-1/2 inch by 4-1/2 inch square corner ball bearing commercial hinge in medium duty, and the Stanley FBB191 is a 5-knuckle full mortise standard weight hinge in 4.5 inch by 4.5 inch.

Both are steel plain bearing residential hinges with square corners. The Ives 1010RP is from the 1000 series and is packed as a set of three, rated medium duty, which suits a door that needs three hinges from one order line. The S44-RS is sold by the pair, is 4 inch by 4 inch, and adds a security tab with a .085 residential thickness leaf.

Prime Coat White is a paintable primed steel finish, meant to be topcoated to match trim or a painted door. It is the finish to order when the hinge should disappear into painted millwork rather than show as a metal accent.

For interior residential doors, yes. It is a single size, 4 by 4 square corner, non-handed, in one primed finish, so unit-to-unit consistency is easy. Where an opening is an entry or exit door taking heavy traffic, step up to a commercial bearing hinge and keep the S44-RS for interiors. Mixing is normal; just keep the corner style and size consistent per door prep.

They address different threat levels. The S44-RS is a residential thickness steel hinge with a security tab and a removable pin. The BEST BB855 is a heavy duty steel double weight concealed ball bearing prison hinge from the detention hardware line, and the Hager 990 STEEL is a full surface prison hinge in 3 inch by 4 inch with a welded tip. Those are detention-grade parts for steel frame institutional openings rather than a drop-in replacement for a 4 inch by 4 inch residential mortise.
