Plain Bearing Hinge: Plain bearing hinges feature knuckles that are machined to a smooth surface, allowing them to move against one another without bearings. Plain bearing hinges are not recommended for heavy use on high traffic entrance ways, but meet the need of a standard residential door.

Material - Steel: Steel is cheap strong and durable making it a favorite for hinges of all types. Though it is more prone to rusting than solid brass or stainless steel.

Mounting: The standard corners for mortised door hinges are 1/4" radius, 5/8" radius and square corner. It is recommended that three hinges be used on doors up to and including 7.5 feet with one additional hinge for each additional 2.5 feet.

Schlage Residential S3P1020FRP619 – Frequently Asked Questions

1) My existing hinges are 3-1/2 inch. Can I use the 4 inch Schlage S3P1020 instead?
Not without re-mortising. A 4 x 4 leaf will not sit in a 3-1/2 x 3-1/2 pocket, and the screw hole pattern lands in different wood. If the door is already cut for 3-1/2 inch square corners, order a 3-1/2 hinge instead, such as the Emtek 91013 residential plain bearing pair in 3-1/2" x 3-1/2" square corner plated steel, or the Deltana DSB35 residential square hinge in the same size. Going the other way, cutting the mortise deeper and longer for a 4 inch hinge is doable on a solid door but is not a swap you make on a hollow core.
2) Are plain bearing hinges like the Schlage S3P1020 OK for a front entry door or an apartment corridor door?
Plain bearing is the wrong choice for high traffic. The S3P1020's knuckles are machined smooth and ride against each other with no bearing, which the manufacturer explicitly does not recommend for heavy use on high traffic entrances. It is a medium duty, residential strength hinge, fine for bedroom, bath, closet and interior doors in a house or apartment unit. For a leasing office door, a corridor door, or any opening cycling all day, step up to a bearing hinge such as the Ives 3CB1 concealed bearing full mortise hinge, or the Delaney CH401X 4" x 4" commercial ball bearing hinge in square corner if you need to keep the same 4 x 4 square corner prep.
3) The doors take a lot of traffic - what should I use instead of the Schlage S3P1020 plain bearing hinge?
Plain bearing knuckles ride against one another without bearings, which suits a standard residential door rather than a high-traffic entrance. For heavier cycling at the same square corner profile, the Delaney CH401X is a 4" x 4" commercial ball bearing hinge with square corners - the same size and corner prep as the S3P1020 with a ball bearing knuckle. At 4-1/2" x 4-1/2", the Orca 3535 Series is a square corner ball bearing commercial hinge, and the Don-Jo HWBB84545 is a heavy weight full mortise ball bearing hinge in satin chrome at that size. The larger leaf needs a wider mortise, so confirm the door prep before switching sizes.
4) What is the closest match to the Schlage S3P1020 4 inch square corner hinge from another brand?
The Ives 1010RP is the nearest counterpart. Like the Schlage S3P1020, it is a steel plain bearing residential hinge with square corners, carries a medium duty rating, and is sold as a set of three - the same three-hinge pack the S3P1020 ships in. Both sit in the 1000 series. If you are matching an opening already hung on 4 inch square corner plain bearing hinges and want a like-for-like swap, the 1010RP is the one to look at.
5) My door frame is cut for 5/8 inch radius corners, not square - what 4 inch residential hinge fits?
The Schlage S3P1020 is a square corner hinge, so it will not drop into a mortise routed for a radius corner. For a 4" x 4" opening prepped with a 5/8" radius, the Delaney RH45xx exterior residential hinge and the Delaney RH40xx Castlegate hinge are both 4" x 4" with a 5/8" radius and ship as a pair. Check the existing hinge corner before you order - a square corner leaf in a radiused pocket leaves gaps at the corners.
6) Does the Schlage S3P1020 give me a secure hinge for an out-swinging exterior door?
The S3P1020 has a removable pin, which lets you lift the door off for maintenance but also means the pin is accessible from the hinge side. On an out-swing where the barrel faces outward, buyers typically specify a non-removable pin or security hinge instead. The Deltana CSB45N is a 4-1/2" x 4-1/2" square hinge pair with a non-removable pin, the Deltana DE44R5TA is a 4" x 4" steel security hinge with a 5/8" radius corner sold as a pair, and the Hager BB1168 is a non-removable pin full mortise ball bearing heavy duty hinge.
7) I need to run power through the door for an electrified lock - will the Schlage S3P1020 work?
No. The S3P1020 is a plain bearing mortise hinge with no wiring path through the barrel; power transfer needs a purpose-built hinge. The Command Access ETH-CB70 is an energy transfer hinge with a 3 knuckle standard weight steel base at a medium duty rating, and the ETH-BB68 is the 5 knuckle heavy duty version. If you also need door position status back to the panel, the Command Access ETM-CB70 adds door position sensing on a 3 knuckle steel base and the ETM-BB68 integrates a door position switch on the heavy duty base. The BEST CECB179-12C is a steel full mortise concealed bearing electrified hinge with a 12-wire quick connect if you need more conductors.
8) I need the door to close itself - can the Schlage S3P1020 do that?
No. The S3P1020 is a plain bearing hinge with a removable pin and no closing mechanism, so a door hung on it stays where you leave it. For self-closing without a surface closer, the Stanley 2060R is a full mortise spring hinge with square corners at 4-1/2" x 4-1/2" on a ferrous steel base, rated heavy duty. The square corner matches the S3P1020 prep style, but the larger leaf means a wider mortise on both door and frame.
9) Do the Schlage S3P1020 hinges come with screws, or do I need to buy fasteners separately?
Screws are in the box. The S3P1020 pack ships with wood and machine screws, so a three hinge door is a complete job out of one pack with no separate fastener order. Wood screws go into a wood door and wood jamb; the machine screws are there for a metal frame that is tapped for them.
10) Can I take the door off without unscrewing the hinges?
Yes. The S3P1020 has a removable pin, so you tap the pin up and out and lift the door off the frame with the leaves still screwed to the door and jamb. That is what you want for painting, moving furniture, or swapping a door in a rental turn. Worth knowing on an exterior application: a removable pin on an outswing door means the pin is accessible from outside, so use a non-removable pin hinge there instead, like the Deltana CSB45N square hinge in NRP.
11) What finishes do the Schlage S3P1020 hinges come in to match my lockset?
Six finishes, all Schlage's standard residential codes: 530 Black Stainless, 608 Satin Brass, 619 Satin Nickel, 622 Matte Black, 625 Bright Chrome, and 643E Aged Bronze. Those are the same finish codes Schlage puts on its residential knobs, levers and deadbolts, so if you are standardizing a building on 619 or 622, the hinges call out the same way as the locks. Note the base metal is steel, which is more prone to rust than solid brass or stainless, so keep these to interior openings and covered entries.
12) What is the difference between the Schlage S3P1020 and the Ives 1010RP hinge?
Very little on paper, and that is the point. Both are steel plain bearing residential hinges with square corners, both medium duty, both sold as a set of three, and both are 1000 Series. Ives and Schlage are sister brands under the same parent, so the 1010RP is the closest direct equivalent if the Schlage finish you need is not the one you want. Pick between them on finish and on what the rest of the door hardware in the building already is.
13) Can I use a 3-1/2 inch hinge in place of the Schlage S3P1020?
Only if the door and frame are prepped for the smaller leaf - a 3-1/2" hinge will not fill a mortise cut for the 4" x 4" S3P1020. Where the opening is genuinely 3-1/2", the Emtek 91013 is a residential plain bearing hinge in plated steel with square corners, sold as a pair, which matches the S3P1020 on bearing type and corner style at the smaller size. The Deltana DSB35 is a 3-1/2" x 3-1/2" square residential hinge, also a pair, and the Delaney RH35xx covers 3-1/2" interior residential openings with a 5/8" radius corner.
14) Is a concealed bearing hinge the same thing as the Schlage S3P1020 plain bearing hinge?
No - they are different knuckle constructions. The S3P1020 uses plain bearing knuckles machined smooth so they move against one another without bearings. A concealed bearing hinge such as the Ives 3CB1 carries bearings hidden inside the barrel; it is a 3-knuckle steel full mortise hinge at a medium duty rating, and the 3CB1HW is the heavy weight version. The Hager 920 is a 2-knuckle steel full mortise concealed bearing hinge, also medium duty. The S3P1020 has 5 knuckles, so the barrel appearance differs as well - worth checking if you are matching hinges already hanging on adjacent doors.
15) What is the difference between the Schlage S3P1020 and a Hager 1129 plain bearing hinge?
Both are plain bearing steel hinges, but they mount differently and at different weights. The S3P1020 is a full mortise hinge, meaning both leaves mortise into the door and the frame. The Hager 1129 is a half mortise plain bearing commercial hinge, 4-1/2" standard weight steel, rated heavy duty - half mortise means one leaf mortises into the door while the other surface-applies to the frame, which is how it gets used on channel iron frames. If your prep is a standard mortised wood door and frame, the half mortise leaf will not seat.
16) What 5-knuckle standard weight hinge is comparable to the Schlage S3P1020 for a commercial spec?
The McKinney MP79 MacPro is a 5-knuckle standard weight full mortise hinge, and the MPB79 MacPro is the same 5-knuckle standard weight configuration in the bearing version - both match the S3P1020 on knuckle count and full mortise mounting. The Stanley FBB191 is a 5-knuckle full mortise standard weight hinge at 4-1/2" x 4-1/2", which needs a wider mortise than the 4" x 4" S3P1020. For a non-ferrous leaf, the McKinney T2314 is a standard weight 5-knuckle hinge at a medium duty rating, the same duty level the S3P1020 carries.
17) Which hinges do I use for a detention or correctional opening rather than the Schlage S3P1020?
The S3P1020 is a residential hinge and is not built for detention service. For those openings the BEST BB855 is a heavy-duty steel double weight concealed ball bearing prison hinge from the detention hardware line, and the Stanley double weight prison hinge is a 5" by 6" leaf furnished with no holes and not swaged, so it is drilled and prepped to the frame on site. The Hager 990 STEEL is a 3" x 4" full surface prison hinge with a welded tip, heavy duty - full surface means both leaves apply to the face rather than into a mortise.
18) Is there a heavier plain bearing hinge than the Schlage S3P1020 that keeps the square corner?
The Emtek 92013 is a heavy duty plain bearing hinge in plated steel with square corners, sold as a pair at 3-1/2" x 3-1/2". It keeps the plain bearing knuckle and square corner profile of the S3P1020 at a heavier duty rating, but the smaller leaf means it suits a 3-1/2" prep rather than the 4" x 4" mortise the S3P1020 fills. If you want the heavier build with a bearing knuckle at that size, the Emtek 94013 is the heavy duty ball bearing version, also 3-1/2" square corner in plated steel.
19) Does the Schlage S3P1020 need to be ordered left hand or right hand?
No handing to specify. The S3P1020 is a full mortise butt hinge with a removable pin, symmetrical about the barrel, so the same hinge works on a left hand or right hand door. Mount it with the barrel on the side the door swings toward and the pin head up. Handing only becomes an order line on specialty hinges, for example the Stanley CECB1900R54L electrified hinge, which is called out left-handed.
20) Will these hinges squeak or bind over time?
The knuckles come lubricated from the factory, which is what keeps a plain bearing hinge turning quietly instead of grinding, since there is no bearing race carrying the load. On a residential door at normal cycle counts that holds up. If a plain bearing hinge in your building is already squealing, it is usually a sign the opening is cycling more than a plain bearing is meant to, and the fix is a bearing hinge rather than another plain bearing.
21) Is a pivot an alternative to the Schlage S3P1020 mortise hinge?
They solve different problems. The S3P1020 hangs a door on three mortised hinges along the edge, swinging one way. A pivot such as the BEST DAP-3 is a heavy duty double acting pivot for commercial interior doors - double acting means the door swings both directions, which a mortise hinge cannot do. Pivot prep is at the top and bottom of the door rather than the hinge stile, so it is not a drop-in change to an opening already mortised for hinges.
22) What decorative hinge alternative is there to the plain square barrel of the Schlage S3P1020?
The McKinney SQ3331 is a square barrel 2-knuckle decorative hinge at 4-1/2" by 4-1/2", standard duty. Against the S3P1020's 5-knuckle barrel and square corner leaf, the SQ3331 reads as a squared architectural barrel with only two knuckles. The 4-1/2" leaf is wider than the S3P1020's 4" x 4", so the mortise has to be cut for it - check the existing prep before specifying it as a swap.
