Deltana S35R5N15 – Frequently Asked Questions
1) Are the Deltana S35R5N hinges heavy enough for an apartment entry door or exterior door?
No. The S35R5N is a residential-thickness steel hinge with a plain bearing knuckle, .085 gauge, and Deltana calls the steel line an indoor product. Use it on interior passage and bedroom doors. For an entry door, a unit door in a rental, or anything on a closer, step up to a ball bearing hinge: the Emtek 94013 is a 3-1/2 x 3-1/2 heavy duty ball bearing pair with square corners, or the Ives 3CB1 concealed bearing full mortise hinge if the opening is commercial.
2) Will a 3-1/2 inch 5/8 radius corner hinge drop into my existing door mortise?
It fits if what you pull off the door is also 3-1/2 x 3-1/2 with rounded corners. The S35R5N measures 3-1/2" x 3-1/2" with 5/8" radius corners, which is the standard corner radius routed by residential hinge templates and pre-hung door machines. If the old mortise has sharp square corners, or a tighter 1/4" radius like the Orca 3514 commercial hinge uses, the leaf will not seat without recutting the pocket. Match the corner style before you match anything else.
3) What does NRP mean on a hinge and do I actually need it?
NRP is a non-removable pin: 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. It matters only on out-swinging doors, where the hinge barrel sits on the outside and an intruder could otherwise tap the pins and lift the door off. On an in-swinging door the barrels are already on the secure side and NRP buys you nothing. The S35R5N ships NRP as standard.
4) How is a plain bearing hinge different from a ball bearing hinge, and which should I order?
A plain bearing knuckle has no bearing races, so metal rides on metal. That is fine on a light interior door opened a few times a day, which is what the S35R5N steel hinge is built for. Ball bearing and concealed bearing hinges carry weight and cycle count without wear, and they are what you want under a door closer or on a heavy or high traffic opening. Comparable bearing options include the Emtek 94013 in the same 3-1/2 x 3-1/2 size, or in commercial sizes the Orca 3535 ball bearing hinge and the Don-Jo HWBB74545 heavy weight ball bearing hinge at 4-1/2 x 4-1/2.
5) Can I use the Deltana S35R5N on a fire rated door or a commercial corridor door?
No. This is a residential-duty steel hinge with a plain bearing, sized 3-1/2 x 3-1/2, and the steel line is for indoor residential use. Commercial openings, and anything on a labeled door, need a commercial hinge in a larger size. From what we stock, the Ives 3CB1 or 3CB1HW concealed bearing full mortise hinges and the Hager BB1168 NRP full mortise ball bearing hinge are the commercial direction to go, and the Hager BB1168 also carries the non-removable pin if security on an out-swing is why you were looking at this one.
6) I need a 3-1/2 inch hinge with square corners instead of radius corners. What are my options?
Corner profile has to match the mortise already cut in the door and jamb; a 5/8 inch radius hinge will not sit correctly in a square-cut mortise. The Deltana S35R5N is a 5/8 inch radius corner hinge. For the same 3-1/2 inch by 3-1/2 inch size with square corners, the Emtek 91013 is a residential plain bearing hinge in plated steel sold as a pair, and the Schlage Residential S3P1010 is a 3.5 inch by 3.5 inch square corner plain bearing mortise hinge supplied in packs of three. Both share the S35R5N's plain bearing action; only the corner cut differs.
7) What is the closest equivalent to the Deltana S35R5N 3-1/2 inch residential hinge from another brand?
The Delaney RH35xx is the nearest match: a 3-1/2 inch by 3-1/2 inch steel residential interior hinge with 5/8 inch radius corners, sold as a pair, the same size, corner style and pair packaging as the S35R5N. The difference is the pin. The Deltana S35R5N is built with a non-removable pin, so the pin cannot be driven out from the hinge side once the door is hung. If you are matching size and corner profile on interior openings, the Delaney is a direct fit; if the reason you specified this hinge was the NRP, stay on the S35R5N.
8) If I want the non-removable pin security but on a commercial exterior door, what replaces the Deltana S35R5N?
The Hager BB1168 NRP is the commercial answer to the same problem. It is a non-removable pin full mortise ball bearing hinge rated heavy duty, where the Deltana S35R5N delivers its non-removable pin on a residential-duty plain bearing steel hinge. Both keep the pin from being driven out on the hinge side of an outswing door; the Hager adds ball bearing action and heavy duty construction for the higher cycle count an exterior commercial opening sees.
9) Can I use the Deltana S35R5N where an electrified or door position monitoring hinge is called for?
No, and this is a common mis-substitution because the sizes look comparable. The Deltana S35R5N is a plain mechanical full mortise steel hinge with no wiring path through it. If the drawing calls for power transfer to an electrified lock, the Command Access ETH-CB70 is an energy transfer hinge on a 3 knuckle standard weight steel base, 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 sensing, the Command Access ETM-CB70 is an energy transfer monitor hinge with door position sensing on a 3 knuckle steel base.
10) How many Deltana S35R5N hinges do I need per door, and do they come as a pair?
The S35R5N is sold by the pair. A standard interior door hangs on three hinges, so budget two pairs per door and you will have a spare leaf set, or order per opening accordingly. Screws are included as #9 x 3/4" wood screws, which is a residential-length screw sized for a wood jamb, not for reaching framing behind the jamb.
11) Do these hinges come with screws, or do I need to buy fasteners separately?
Fasteners are in the box. Each pair comes with #9 x 3/4" wood screws, drilled to an arc hole pattern in the leaf. Nothing else is required to hang the door once the mortise is cut. If you are hanging a heavier slab and want to catch the stud behind the jamb, you will need a longer screw than the 3/4" supplied.
12) What finishes do the Deltana S35 steel hinges come in for matching existing door hardware?
Eight finishes on the S35R5N: brushed nickel, antique nickel, polished chrome, paint black, brushed chrome, polished brass, antique brass, and oil rubbed bronze. That spread covers the common residential lever and knob finishes, so a property manager standardizing a building can match hinges to trim across nickel, chrome, brass and bronze families without changing hinge model.
13) Are the Deltana S35R5N hinges handed, or will one pair work on a left or right hand door?
Not handed. Full mortise butt hinges with a straight barrel and a pin are symmetrical, so the same pair hangs a left hand or right hand door. Flip it and the pin runs the other way. What you do have to get right is swing direction rather than hand, because the non-removable pin is only doing work when the barrel ends up on the outside of an out-swinging door.
14) My door is 3/4 inch thick veneer over a hollow core. Will a full mortise hinge work?
Full mortise means both leaves get let into a pocket, one in the door edge and one in the jamb rabbet. That needs enough solid material in the door edge to hold a 3/4" screw in the stile. A standard 1-3/8" hollow core interior door has a solid stile at the edge and takes this fine. A thinner slab or one with no solid edge banding will not hold the #9 x 3/4" screws, and you want a surface-applied or wrap-around hinge instead.
15) Is a 4 inch by 4 inch residential hinge interchangeable with the Deltana S35R5N?
No. The Deltana S35R5N is 3-1/2 inch by 3-1/2 inch, and hinge size is set by the mortise already routed into the door edge and jamb. A 4 inch by 4 inch leaf will not drop into a 3-1/2 inch pocket without recutting both. The Delaney RH45xx is a 4 inch by 4 inch bulk residential exterior hinge with 5/8 inch radius corners sold as a pair, and the Orca Hardware COM4040 is a 4 inch by 4 inch square corner plain bearing commercial hinge - both correct choices when the opening is already prepped for 4 inch, and neither a swap for a 3-1/2 inch prep.
16) What is the difference between the Deltana S35R5N and a ball bearing hinge in the same size?
Bearing type is the difference. The Deltana S35R5N uses a plain bearing, where the knuckles ride directly on each other - standard practice on residential-weight doors that see moderate use. A ball bearing hinge places bearings between the knuckles to carry heavier leaves and higher cycle counts. In the same 3-1/2 inch by 3-1/2 inch size, the Emtek 94013 is a heavy duty ball bearing hinge in plated steel with square corners, sold as a pair. Note the square corners on the Emtek against the 5/8 inch radius on the Deltana - the mortise profile differs even though the size matches.
17) We are standardizing hinges across a multi-family property. How do the Deltana S35R5N and the Emtek 91013 differ for a fleet buy?
Both are residential-duty plain bearing steel hinges at 3-1/2 inch by 3-1/2 inch, sold by the pair, so the leaf size matches across a building. Two things separate them. Corners: the Deltana S35R5N is cut with 5/8 inch radius corners, the Emtek 91013 with square corners, so whichever profile is already routed into your door stock decides it. Pin: the S35R5N is supplied with a non-removable pin. If your unit entry doors swing out into a corridor, that NRP matters on the entries even if interior passage doors do not need it.
18) What is a step up from the Deltana S35R5N if I want a heavier hinge but the same 3-1/2 inch mortise?
The Emtek 92013 keeps the plain bearing action and the 3-1/2 inch by 3-1/2 inch size of the Deltana S35R5N in plated steel, but is built to a heavy duty plain bearing spec rather than residential. The Emtek 96213 is another heavy duty hinge at the same 3-1/2 inch size. Both are cut with square corners, where the Deltana uses 5/8 inch radius corners, so confirm the mortise profile in the door before ordering either.
19) Will a half mortise or full surface hinge work in place of the Deltana S35R5N?
No. The Deltana S35R5N is a full mortise hinge, meaning both leaves recess into routed pockets, one in the door edge and one in the jamb. A half mortise hinge such as the Hager 1129 mortises into the door but attaches to the face of the frame, and a full surface hinge such as the Hager 990 STEEL prison hinge mounts to the faces of both door and frame. Those mount into different preps entirely and cannot be dropped into a full mortise pocket.
20) Is the Deltana S35R5N solid brass or plated steel?
Steel, both the base material and the substrate, with the finish applied over it. That is why Deltana positions the S35 as the value line rather than the solid brass line. For an interior door in a dry, conditioned space it holds up; in a bathroom, a coastal exterior, or anywhere with standing moisture, plated steel will eventually show through at the knuckle.
