Baldwin 1140031I – Frequently Asked Questions
1) Will the Baldwin Reserve 1140 hinge drop into an existing 5/8 inch radius corner mortise?
Yes, if the existing pocket is a 4 x 4 inch mortise with 5/8 inch radius corners. The 1140 is a 4 x 4 full mortise hinge cut with 5/8 inch radius corners, so it lands in a router-cut pocket made with the common 5/8 inch radius template. If your jambs and doors were cut square-corner, the 1140 will leave gaps at the corners and you want a square corner hinge instead.
2) I need a 3-1/2 inch radius corner hinge, not 4 inch. What are my options?
The Reserve 1140 is built in 4 x 4 inch only, so it will not fill a 3-1/2 inch mortise. For a smaller radius corner pocket, the Delaney RH35xx is a 3-1/2 x 3-1/2 inch residential hinge with 5/8 inch radius corners, sold in pairs. The Orca Hardware 3514 Series is a 3-1/2 x 3-1/2 inch commercial hinge but cut with a 1/4 inch radius, which is a different corner and will not match a 5/8 inch pocket.
3) I need a non-removable pin on an out-swinging door. What do I use if the 1140 cannot be ordered that way?
Non-removable pins are not offered on the Baldwin Reserve 1140 because that option is not made on radius corner hinges. For an out-swinging door where the barrel is exposed on the secure side, Hager's BB1168 is a non-removable pin full mortise ball bearing heavy duty hinge, and Deltana's CSB45N is a 4-1/2 inch by 4-1/2 inch square hinge pair furnished with a non-removable pin. Deltana's DE44R5TA is a 4 inch by 4 inch by 5/8 inch radius steel security hinge and holds the same radius corner as the 1140, so it fits an existing 1140 mortise.
4) I need the hinge to carry power to an electrified lock. Will the Baldwin Reserve 1140 do that?
No. The Baldwin Reserve 1140 is a plain full mortise hinge with a stainless steel pin and no wiring path through the barrel. To transfer power through the hinge, use an energy transfer hinge: the Command Access ETH-BB68 is a 5 knuckle heavy duty steel base energy transfer hinge, and the ETH-CB70 is a 3 knuckle standard weight version. If the opening also needs door position monitoring, the Command Access ETM-BB68 integrates a door position switch and the ETM-CB70 adds door position sensing on a 3 knuckle steel base. BEST's CECB179-12C is a steel full mortise concealed bearing electrified hinge with a 12-wire quick connect.
5) What is the closest match to a Baldwin Reserve 1140 hinge if I need a 4 inch by 4 inch with 5/8 inch radius corners from another brand?
The Baldwin Reserve 1140 is a 4 inch by 4 inch hinge with 5/8 inch radius corners. Delaney offers two 4 inch by 4 inch residential hinges with the same 5/8 inch radius corner profile: the RH45xx bulk exterior residential hinge and the RH40xx for Castlegate, which comes 5/8 inch radius by square. Deltana's DE44R5TA is also a 4 inch by 4 inch by 5/8 inch radius hinge, built as a steel security hinge. All three drop into a mortise cut for a 5/8 inch radius corner, so no router work is needed at the jamb or door edge. Delaney and Deltana ship as pairs; the 1140 is packed one per box.
6) My existing hinges have 1/4 inch radius corners, not 5/8 inch. What should I order instead?
Radius corners are not interchangeable between the two common radii, and cutting a 5/8 inch radius hinge into a 1/4 inch mortise leaves a gap at each corner. The Baldwin Reserve 1140 is a 5/8 inch radius corner hinge. For a 1/4 inch radius mortise in the same 4 inch by 4 inch size, Orca Hardware's COM4014 is a 4 inch by 4 inch by 1/4 inch radius corner plain bearing commercial hinge. If the opening is 3-1/2 inch by 3-1/2 inch, Orca's COM3514 is the same 1/4 inch radius profile in that size. Measure the existing corner before ordering.
7) The door I am rehanging has square corner hinge mortises. What is the equivalent to the 1140 in square corner?
The Baldwin Reserve 1140 is cut with 5/8 inch radius corners and will not fill a square corner mortise. In the same 4 inch by 4 inch footprint, Orca Hardware's COM4040 is a square corner plain bearing commercial hinge and Delaney's CH401X is a 4 inch by 4 inch square corner commercial ball bearing hinge. Deltana's CSB45N is a square hinge in 4-1/2 inch by 4-1/2 inch with a non-removable pin, which suits an out-swinging exterior door; note the 1140 is not offered with non-removable pins because that option is not made on radius corner hinges.
8) What hinge should I use on a heavy solid core or exterior door instead of a 4 inch by 4 inch residential hinge?
The Baldwin Reserve 1140 is a residential 4 inch by 4 inch hinge with a .090 inch leaf thickness. A heavier door is typically hung on a larger, thicker heavy weight ball bearing leaf. Don-Jo's HWBB84545 is a heavy weight full mortise ball bearing hinge at 4-1/2 inch by 4-1/2 inch in satin chrome, and the HWBB75045 is a heavy weight full mortise ball bearing hinge at 5 inch by 4-1/2 inch in steel. Stanley Security's FBB191 is a 5-knuckle full mortise standard weight hinge at 4.5 inch by 4.5 inch. Going up in leaf size means enlarging the mortise on both the door and the jamb.
9) How thick is the Baldwin Reserve 1140 hinge leaf, and does that matter for the mortise depth?
Leaf thickness is .090 inches. That is the depth your mortise needs to be routed to so the leaf sits flush with the door edge and jamb face. Cut deeper and the door binds against the stop; cut shallower and the door stands proud and the gap opens up.
10) Do Baldwin 1140 hinges come with screws, or do I need to buy fasteners separately?
Screws are in the box. Each hinge is poly-bagged with #10 x 1 inch flat head Phillips wood screws, packed one hinge per box. That screw length is sized for wood jambs and solid wood doors. On a hollow metal frame or a mineral core door you will need machine screws instead.
11) Are Baldwin 1140 hinges sold individually or as a pair?
Individually. Packing is one per box, so a standard three-hinge door means ordering three, and a tall door on four hinges means four. Several comparable residential hinges are sold as pairs (the Delaney RH45xx 4 x 4 inch 5/8 inch radius exterior hinges, for example), so watch the count when you are cross-shopping.
12) What finishes does the Baldwin Reserve 1140 radius corner hinge come in?
Fifteen finishes, so you can match the hinges to Baldwin Reserve trim already on the openings: 003 Polished Brass PVD, 031 Non-Lacquered Brass, 033 Vintage Brass, 044 Satin Brass PVD, 050 Satin Brass Black, 055 Polished Nickel PVD, 056 Lifetime PVD Satin Nickel, 060 Satin Brass and Brown, 076 Lifetime PVD Graphite Nickel, 102 Oil Rubbed Bronze, 112 Venetian Bronze, 151 Antique Nickel, 190 Satin Black, 260 Polished Chrome, and 402 Distressed Oil Rubbed Bronze. The 031 non-lacquered brass is a living finish and will darken with handling; the PVD finishes hold their color.
13) Does the Baldwin Reserve 1140 need to be handed when I order it?
No handing to specify. The 1140 is a standard full mortise butt hinge in 4 x 4 inch, symmetrical about the barrel, so one part number works on left hand and right hand doors. All you pick is the finish. Handing only comes up on hinge types like the Stanley CECB1900R54L, a left-handed concealed conductor hinge, where the wire exit fixes the side.
14) Is the Baldwin 1140 a ball bearing hinge?
The 1140 is a machined solid brass butt hinge on stainless steel pins, not a bearing hinge. For a heavier door or a high-cycle opening where you want bearings, look at the Emtek 94013 heavy duty ball bearing hinges or the Don-Jo HWBB74545, a 4-1/2 x 4-1/2 inch heavy weight full mortise ball bearing hinge. Note that both are different sizes or corner styles, so check them against your existing mortise before you swap.
15) What is the difference between the Baldwin Reserve 1140 and a concealed bearing hinge like the Hager 920 or Ives 3CB1?
The Baldwin Reserve 1140 is a solid brass residential hinge with a visible knuckle barrel and a stainless steel pin, chosen partly for how it looks in finishes like 190 satin black and 260 polished chrome. A concealed bearing hinge hides the bearing inside the knuckle for a plain barrel line: the Hager 920 is a full mortise concealed plain bearing 2 knuckle steel hinge rated medium duty, and the Ives 3CB1-B is a 3-knuckle concealed bearing full mortise hinge, also medium duty. Those are steel commercial hinges specified for cycle life; the 1140 is specified for the residential opening and the finish match.
16) What is a simpler steel alternative to the Baldwin Reserve 1140 for interior doors I do not need to match a decorative finish on?
The Baldwin Reserve 1140 is a solid brass Reserve Series hinge offered in fifteen finishes including 031 non-lacquered brass, 151 antique nickel and 402 distressed oil rubbed bronze, which is what a buyer pays for when the hinge is seen. Where the hinge is behind a door that is never scrutinized, Delaney's RH35xx is a bulk steel residential interior hinge at 3-1/2 inch by 3-1/2 inch with the same 5/8 inch radius corner. Emtek's 91013 is a residential plain bearing hinge pair in plated steel at 3-1/2 inch by 3-1/2 inch, though with square corners. Both are smaller leaves, so confirm the door weight and existing mortise size before switching.
17) I want the hinge to close the door on its own. Is there a self-closing version of the 1140?
The Baldwin Reserve 1140 is a standard full mortise hinge with no closing mechanism in the barrel. For a hinge that returns the door itself, the Stanley Security 2060R is a full mortise spring hinge in 4-1/2 inch by 4-1/2 inch with square corners on a ferrous steel base. It is a square corner leaf, so the mortise corners have to be squared off if the door is currently cut for the 1140's 5/8 inch radius.
18) For a door that has to swing both directions, is a hinge like the 1140 the right choice?
No. The Baldwin Reserve 1140 is a full mortise butt hinge and swings one way only. A door that must swing in both directions runs on a double acting pivot, such as the BEST DAP-3 heavy duty double acting pivot for commercial interior doors. The pivot mounts at the top and bottom of the door rather than in leaf mortises on the edge, so it is a different door prep entirely, not a swap into the same cutouts.
19) Is the Deltana DE44R5TA a straight substitute for the Baldwin Reserve 1140?
They share the same 4 inch by 4 inch leaf with a 5/8 inch radius corner, so they seat in the same mortise. The differences are material and intent: the 1140 is a solid brass Reserve Series hinge supplied one per box with #10 by 1 inch flat head Phillips wood screws and stainless steel rust-proof pins, offered in finishes such as 003 polished brass PVD and 056 lifetime PVD satin nickel. The Deltana DE44R5TA is a steel security hinge with tamper-resistant treatment, sold as a pair. Choose on whether the opening calls for a visible decorative brass hinge or a steel security hinge on an out-swinging door.
20) Do I need a ball bearing hinge, or is the Baldwin Reserve 1140 enough for an interior residential door?
The Baldwin Reserve 1140 is a residential hinge, machined for smooth movement and fitted with stainless steel rust-proof pins. Ball bearing and concealed bearing hinges carry higher cycle traffic: Emtek's 94013 is a heavy duty ball bearing hinge pair at 3-1/2 inch by 3-1/2 inch in plated steel with square corners, Orca's COM3535 is a 4-1/2 inch by 4-1/2 inch square corner ball bearing commercial hinge, and Ives 3CB1 is a medium duty concealed bearing full mortise hinge. For a bedroom or closet door in a house, the 1140 covers it; for a corridor door cycled all day in a multi-family or hospitality building, a bearing hinge is the usual specification.
21) Is a half mortise or full surface hinge an alternative to the Baldwin Reserve 1140?
No, those are different door preps. The Baldwin Reserve 1140 is a full mortise hinge, meaning both leaves are recessed into the door edge and the jamb. Hager's 1129 is a half mortise plain bearing commercial hinge at 4-1/2 inch, which mortises into the door but applies to the face of the frame. Hager's 990 STEEL is a full surface prison hinge at 3 inch by 4 inch with a welded tip, applied to the face of both the door and the frame. Neither will seat in a mortise cut for the 1140.
22) For a detention or high security opening, can I specify the Baldwin Reserve 1140?
No. The Baldwin Reserve 1140 is a residential solid brass hinge. Detention openings use purpose-built hinges: the BEST BB855 is a heavy duty steel double weight concealed ball bearing prison hinge in the detention hardware line, and the Stanley Security BB855 is a double weight prison hinge at 5 inch by 6 inch furnished with no holes and not swaged, so it is drilled and swaged to the specific frame. Hager's 990 STEEL is a full surface prison hinge at 3 inch by 4 inch with a welded tip.
23) I am standardizing hinges across a building and want one decorative hinge line plus a commercial line. How do the Baldwin Reserve 1140 and the McKinney MacPro compare?
The Baldwin Reserve 1140 covers the decorative side: 4 inch by 4 inch, 5/8 inch radius corners, solid brass, and fifteen finishes running from 044 satin brass PVD to 112 venetian bronze, so unit entry doors can match the rest of the trim package. For back of house and corridor openings, the McKinney MP79 MacPro is a 5-knuckle full mortise standard weight hinge and the MPB79 MacPro is a 5-knuckle standard weight hinge, both standard duty. The McKinney T2314 is a non-ferrous 5 knuckle standard weight hinge rated medium duty, which is the one to use where corrosion is a concern.
24) Are the Ives 1010RP and the Baldwin Reserve 1140 the same kind of residential hinge?
Both are residential mortise hinges, but they are not interchangeable in an existing mortise. The Ives 1010RP is a steel plain bearing residential hinge with square corners, medium duty, sold as a set of three. The Baldwin Reserve 1140 is a 4 inch by 4 inch solid brass hinge with 5/8 inch radius corners, packed one per box with #10 by 1 inch flat head Phillips wood screws. The corner profile is the deciding factor: a square corner leaf leaves radiused voids in a 1140 mortise, and a radius leaf leaves square gaps in a 1010RP mortise.
25) For an exterior residential door, is the Baldwin Reserve 1140 or the Delaney RH45xx the right pick?
Both are 4 inch by 4 inch with a 5/8 inch radius corner, so either seats in the same mortise. The Delaney RH45xx is a bulk residential exterior hinge sold in pairs, which suits hanging a run of exterior doors on one job. The Baldwin Reserve 1140 is solid brass with stainless steel rust-proof pins and comes one per box in fifteen finishes including 102 oil rubbed bronze and 055 polished nickel PVD, which matters when the hinge has to match the entry set. Pick on whether the door is a quantity hang or a finish-matched entry.
26) Why does the Baldwin 1140 have a bevel on the inside leaf?
The inside leaf is beveled so the two leaves close up tight against each other when the door is shut. Standing in front of a closed door you see a clean joint at the barrel rather than a gap, which is the point of using a solid brass hinge on a finished opening in the first place.
27) Will the pins on the Baldwin 1140 rust on an exterior door?
The pins are stainless steel and rust-proof, so they hold up on an entry door where a plated steel pin would eventually stain the jamb. Note that no non-removable pin option exists on the radius corner hinges, which is a separate consideration on an outswing exterior door.
28) If I want a decorative barrel look other than the standard Baldwin Reserve 1140 knuckle, what else is there?
The Baldwin Reserve 1140 uses a conventional knuckled barrel in a 4 inch by 4 inch leaf with 5/8 inch radius corners, finished in options such as 033 vintage brass and 076 lifetime PVD graphite nickel. For a different barrel profile, the McKinney SQ3331 is a square barrel 2-knuckle decorative hinge at 4-1/2 inch by 4-1/2 inch, standard duty. It is a larger leaf, so the mortise has to be enlarged rather than reused.
