Deltana S44R4HDN 4" x 4" x 1/4" Radius Hinge, NRP, Heavy-Duty, Steel (Pair)

Yes. The S44R4HDN is a 4 x 4 inch full mortise hinge with 1/4 inch radius corners, so it drops into an existing 4 x 4 mortise cut with 1/4 inch radius. If the pockets in your jamb and door are square-cornered, or cut with the 5/8 inch radius common on residential prehung doors, the leaf will not seat flush and you will be re-routing the mortise. Pull one existing hinge first and match the corner radius, not just the 4 x 4 size.

NRP is a non-removable pin, and the S44R4HDN has it. A set screw in the barrel seats into a groove in the pin so the pin cannot be driven out while the door is closed. That matters on any outswing door where the hinge barrels are on the outside, an exterior entry, a tenant unit door, a storage or utility room. Someone could otherwise tap the pins out and lift the door off its frame regardless of what lock is on it. On an inswing door with the barrels inside, NRP buys you nothing.

No. The S44R4HDN is a plain bearing hinge in Deltana's residential line, heavy duty within that line. Plain bearing means metal riding on metal at the knuckle rather than a bearing race, which is fine for a house or an apartment interior door but wears and squeaks under the cycle counts an office, school, or retail entrance sees. For those openings go to a bearing hinge: the Ives 3CB1HW is a heavy weight concealed bearing full mortise hinge, and the Hager BB1168 is a heavy duty full mortise ball bearing hinge that also comes non-removable pin if you need the security the S44 gives you.

Deltana lists the S44 steel hinges as a value choice for indoor applications. Steel base metal plated to a decorative finish will eventually corrode on a weather-exposed opening, so for a true exterior door use a hinge specified for it. Among exterior-rated residential options, the Delaney 4 x 4 bulk residential exterior hinge carries a 5/8 inch radius corner, which is a different mortise than the S44's 1/4 inch radius, so check your pocket before switching.

No. The S44R4HDN is a plain mechanical full mortise hinge in steel with no wire path through it. Transferring power to an electrified lock or exit device through the hinge takes a purpose-built hinge: the Command Access ETH-BB68 is a 5 knuckle heavy duty steel base energy transfer hinge, the ETH-CB70 is the 3 knuckle standard weight version, and the BEST CECB179-12C is a steel full mortise concealed bearing electrified hinge with a 12-wire quick connect. If the opening also needs door position monitoring, the Command Access ETM-BB68 adds an integrated door position switch. Use the S44R4HDN on the remaining non-electrified hinge locations of that same door.

The Orca Hardware 4014 Series is the closest match by size and corner profile: it is a 4" x 4" x 1/4" radius corner plain bearing hinge, the same 4" x 4" size and the same 1/4" radius corner style as the S44R4HDN, and the same plain bearing type. Two differences a locksmith or contractor should confirm before swapping: the S44R4HDN is a heavy-duty steel hinge supplied with a non-removable pin, and the Orca 4014 is rated medium duty. If the opening was speced for NRP on an out-swinging door, the pin treatment is the deciding detail, not the size.

The S44R4HDN has 1/4" radius corners, which will not seat correctly in a square corner mortise. For a square corner 4" x 4" prep, the Orca Hardware 4040 Series is a 4" x 4" square corner plain bearing commercial hinge, the same size and same bearing type with the corner profile your prep needs. The Delaney CH401X is another 4" x 4" square corner option, built as a ball bearing hinge. Corner style is the one thing you cannot field-modify on an existing mortise, so measure the prep before ordering.

The S44R4HDN is a plain bearing steel hinge, which Deltana positions for residential use. Plain bearing hinges carry the leaf load on the knuckles themselves; ball bearing and concealed bearing hinges add bearings between the knuckles, which is the construction commercial specs typically call for on doors that cycle constantly. If the opening is commercial traffic, the Ives 3CB1HW is a steel heavy weight concealed bearing full mortise hinge, and the Don-Jo HWBB84545 is a heavy weight full mortise ball bearing hinge in 4-1/2" x 4-1/2". Note the size change: those 4-1/2" hinges need a 4-1/2" prep, so they are not a drop-in for a 4" x 4" mortise.

The S44R4HDN is supplied with a non-removable pin, which is the standard answer for an out-swinging door where the hinge barrel is on the exposed side. It is a heavy-duty plain bearing steel hinge at 4" x 4". If the opening needs a bearing hinge with the same pin security, the Hager BB1168 is a non-removable pin full mortise ball bearing heavy duty hinge. A locksmith retrofitting a commercial exterior opening usually wants the ball bearing version; a property manager replacing hinges on residential exteriors is generally matching what the S44R4HDN already is.

No. The S44R4HDN is a full mortise hinge, meaning both leaves mortise into the door edge and the frame rabbet. A half mortise prep mortises the door leaf only and surface-applies the frame leaf; the Hager 1129 is a half mortise plain bearing commercial hinge at 4-1/2" standard weight steel for that condition. Where nothing is mortised at all, the Hager 990 is a full surface hinge, 3" x 4" with a welded tip. Confirm which prep the frame carries before ordering, since the three mounting methods are not interchangeable.

They look close and are not the same. Both are 4" x 4" steel residential hinges sold in pairs, but the Delaney RH45xx exterior residential hinge has a 5/8" radius corner, while the S44R4HDN has 1/4" radius corners. A 5/8" radius leaf will not fill a 1/4" radius mortise and vice versa, so the two are not cross-compatible on an existing prep. The S44R4HDN also carries a non-removable pin, which matters on an out-swinging exterior door.

Screws are included. Each hinge ships with #12 x 1 inch wood screws for a wood jamb and door, plus #12 x 1/2 inch machine screws for a hollow metal frame that is drilled and tapped. Nothing else is required to hang the door. If you are anchoring into a wood jamb carrying a heavy solid core slab, plenty of installers swap one screw per leaf for a longer one that reaches the framing stud, but that is a longer screw you supply, not a missing part.

No handing to specify. The S44R4HDN is a full mortise butt hinge with a removable-pin-style barrel locked by an NRP set screw, symmetrical leaves, and it hangs on a left or right door either way. The only thing that changes is which side the barrel and set screw face once installed. Finish is the single choice on the order.

The Orca Hardware 4 x 4 x 1/4 inch radius corner plain bearing hinge is the direct dimensional match, same size, same corner radius, same plain bearing, and it drops into the identical mortise. Two differences decide it: Orca lists that hinge as a medium duty commercial hinge, and the Deltana carries the non-removable pin. If the opening needs pin security, stay with the S44R4HDN. If you want a square-corner pocket instead, Orca also builds a 4 x 4 square corner plain bearing hinge.

Yes, if the frame is prepped for a 4 x 4 hinge with 1/4 inch radius corners. Hollow metal frames are drilled and tapped, and the pack includes #12 x 1/2 inch machine screws for exactly that. Be aware most commercial hollow metal is prepped for 4-1/2 x 4-1/2 with square corners, so verify the frame's actual prep, and note this is a residential-line plain bearing hinge, not a bearing hinge for a high-cycle commercial opening.

Interior doors that swing inward do not expose the hinge barrel, so the non-removable pin on the S44R4HDN is not doing work there. For plain interior residential openings the Delaney RH35xx is a 3-1/2" x 3-1/2" bulk steel residential interior hinge with a 5/8" radius, sold in pairs like the S44R4HDN, and the Emtek 91013 is a residential plain bearing hinge pair at 3-1/2" x 3-1/2" with square corners in plated steel. Both are a smaller leaf and a different corner profile, so they suit new prep or a matching existing 3-1/2" mortise rather than a 4" x 4" opening.

Not as a direct swap on the same prep. Both are plain bearing hinges sold in pairs, and the Emtek 92013 is a heavy duty plain bearing hinge in plated steel, so the construction logic lines up. The dimensions do not: the 92013 is 3-1/2" x 3-1/2" with square corners, while the S44R4HDN is 4" x 4" with 1/4" radius corners. A 3-1/2" square corner hinge leaves the mortise short on all four sides of a 4" radius prep. Use the 92013 where the door is already prepped for 3-1/2" square corner, and keep the S44R4HDN for the 4" radius openings.

The S44R4HDN itself is a 4" x 4" hinge with 1/4" radius corners. For a 3-1/2" prep cut with the same 1/4" radius, the Orca Hardware 3514 Series is a 3.5" x 3.5" x 1/4" radius corner plain bearing commercial hinge, matching both the corner radius and the bearing type at the smaller leaf size. Watch that the Orca 3514 is rated medium duty while the S44R4HDN is heavy-duty, and the S44R4HDN carries a non-removable pin.

The non-removable pin on the S44R4HDN stops the pin being driven out from the exposed side, which is what an exterior out-swinging residential door needs. Detention openings are built to a different standard. The BEST BB855 is a heavy-duty steel double weight concealed ball bearing prison hinge in the detention hardware line, and the Stanley BB855 is a double weight prison hinge at 5" by 6" furnished with no holes and not swaged, so it is welded in rather than screwed. Those are the products speced for correctional work; the S44R4HDN suits the administrative and residential doors elsewhere in the facility.

Both are steel plain bearing hinges for residential openings, and both are things a property manager buys by the fleet. The differences that decide the order: the S44R4HDN is 4" x 4" with 1/4" radius corners, sold in pairs, and carries a non-removable pin; the Ives 1010RP is a steel plain bearing residential hinge with square corners sold as a set of three, rated medium duty. Match the corner profile and leaf size to the existing mortise, and count what you need per door before choosing between a pair and a set of three.

No. The S44R4HDN is a full mortise butt hinge, which swings a door one direction from a fixed frame edge. A door that swings both ways needs a pivot instead: the BEST DAP-3 is a heavy duty double acting pivot for commercial interior doors. Pivots also carry the leaf weight at the floor and header rather than along the frame rabbet, so the frame prep is entirely different from a hinge mortise.

The S44R4HDN is a steel hinge with a steel substrate, offered in finishes including polished brass and antique brass. Where the environment argues against a ferrous base, the McKinney T2314 is a non ferrous hinge, standard weight, 5 knuckle, rated medium duty. Non ferrous base material is the reason to choose it over a plated steel hinge on an exposed or wet opening; note the duty rating differs from the heavy-duty S44R4HDN.

.129 inch steel. That gauge is what separates this from a thin builder hinge, and it is why the S44 holds a solid core or heavier slab without the leaves splaying at the barrel over time. Steel base metal, plated to the finish you select.

The S44R4HDN is a steel hinge offered in oil rubbed bronze, brushed nickel, antique nickel, polished chrome, brushed chrome, polished brass, and antique brass, so it already covers most residential trim palettes with a standard square barrel. If the design calls for a visible barrel detail, the McKinney SQ3331 is a square barrel 2-knuckle decorative hinge at 4-1/2" by 4-1/2", standard duty. That is a larger leaf on a different prep and a 2-knuckle rather than a full-knuckle barrel, so treat it as a design decision at new prep, not a finish-match swap into an existing 4" mortise.

The S44 Series S44R4HDN is a steel plain bearing hinge at 4" x 4" with 1/4" radius corners, supplied in pairs with a non-removable pin, and Deltana positions the line for residential interior use. The McKinney MP79 MacPro is a 5-knuckle full mortise hinge rated standard weight, and the MPB79 is the MacPro 5-knuckle standard weight hinge as well. For a distributor stocking both, the identifying differences are the bearing type, the corner radius, and the pin treatment rather than the mounting method, which is full mortise on both sides.
