Baldwin 1045112I – Frequently Asked Questions

1) Is the Baldwin Estate 1045 hinge sold individually or as a pair?
Each Baldwin Estate 1045 square corner hinge is sold as a single hinge, not a pair. A standard interior door usually takes three, so plan quantity accordingly. Wood screws come with each hinge. Several competing residential hinges are packaged differently, for example the Deltana CSB45N 4-1/2 x 4-1/2 square hinge ships as a pair and the Schlage Residential S3P1010 comes in a pack of three, so compare the order quantity, not just the unit.
2) Should I order the removable pin or the non-removable pin version?
Pin style is the choice to get right on an exterior door. Every finish of the Estate 1045 comes both ways. Non-removable pin (NRP) is what you want on an out-swinging exterior door, where the barrel is exposed on the outside and the pin could otherwise be driven out. Removable pin is fine for interior doors and makes it easy to lift the door off for painting or flooring work.
3) I need a 4-1/2 inch square corner hinge for a commercial opening instead of the Baldwin Estate 1045 - what should I use?
The Baldwin Estate 1045 is a residential-strength plain bearing hinge in a 4-1/2 by 4-1/2 square corner size. For a commercial opening at the same size and corner, the Orca Hardware 3535 Series is a 4-1/2 by 4-1/2 square corner ball bearing commercial hinge rated medium duty, and the Don-Jo HWBB84545 is a 4-1/2 by 4-1/2 heavy weight full mortise ball bearing hinge in satin chrome. Both use a bearing knuckle rather than the plain bearing found on the Baldwin.
4) What should I use instead of the Baldwin Estate 1045 if the door needs to self-close?
The Baldwin Estate 1045 is a standard full mortise hinge with no closing mechanism. For a self-closing opening at the same 4-1/2 by 4-1/2 square corner size, the Stanley Security 2060R is a full mortise spring hinge with square corners at 4-1/2 by 4-1/2 on a ferrous steel base, rated heavy duty.
5) What is the closest 4-1/2 inch square corner equivalent to the Baldwin Estate 1045 hinge in a pair?
The Deltana CSB45N is a 4-1/2 inch by 4-1/2 inch square corner hinge sold as a pair with a non-removable pin, which matches the Baldwin Estate 1045's 4-1/2 by 4-1/2 size and square corner style. The Baldwin 1045 is sold as a single hinge and is offered in both removable pin and non-removable pin, so if you need NRP on an outswing exterior door either will give you that; the difference is buying by the hinge versus buying by the pair.
6) Is the Baldwin Estate 1045 a substitute for a ball bearing hinge on a heavy solid core door?
No. The Baldwin Estate 1045 is a plain bearing hinge at residential strength, machined from solid brass. For heavy door leaves, the ball bearing options at 4-1/2 by 4-1/2 include the Don-Jo HWBB74545 and HWBB84545, both heavy duty full mortise ball bearing hinges, and the Hager BB1168, a heavy duty full mortise ball bearing hinge with a non-removable pin. If the leaf is taller or heavier, the Don-Jo HWBB75045 is a 5 inch by 4-1/2 inch heavy weight ball bearing hinge.
7) Can the Baldwin Estate 1045 carry power to an electrified lock?
No. The Baldwin Estate 1045 is a plain bearing brass hinge with no wiring path. For power transfer through the hinge at a comparable size, the Stanley CECB1900R54L is a three knuckle concealed bearing concealed conductor hinge, steel full mortise, 4-1/2 by 4-1/2, square corner, left handed, with 4 wires. The Command Access ETH-CB70 is a 3 knuckle standard weight energy transfer hinge on a steel base, and the BEST CECB179-12C is a steel full mortise concealed bearing electrified hinge with a 12-wire quick connect.
8) Will these hinges match my other Baldwin door hardware finishes?
That is the point of the Estate line. The 1045 is finished to the same Baldwin finish codes as their decorative knobs, levers, and trim, so a 055 Polished Nickel PVD hinge matches 055 hardware elsewhere in the house. Sixteen finishes are offered, including 003 Polished Brass PVD, 031 Non-Lacquered Brass, 033 Vintage Brass, 044 Satin Brass PVD, 050 Satin Brass Black, 056 Lifetime PVD Satin Nickel, 060 Satin Brass and Brown, 076 Lifetime PVD Graphite Nickel, 102 Oil Rubbed Bronze, 112 Venetian Bronze, 140 Bright Nickel, 151 Antique Nickel, 190 Satin Black, 260 Polished Chrome, and 402 Distressed Oil Rubbed Bronze.
9) What is the Baldwin Estate hinge made of, and does it hold up better than a plated steel hinge?
Solid brass. The leaves are machined from solid brass bar stock cut from brass extrusions, which is why the tolerances are tight and the wear performance is better than a stamped, plated-steel residential hinge. Solid brass also means the finish is on brass rather than plating over steel. For contrast, the Emtek 91013 residential plain bearing hinge is plated steel.
10) Is the Baldwin Estate 1045 a full mortise hinge, and does it need to be mortised into the door and frame?
Yes, it is a full mortise hinge, meaning both leaves recess into pockets, one in the door edge and one in the jamb. It is not a surface-applied or half mortise hinge. If your frame is set up for a half mortise (leaf surface-applied to the frame), the 1045 is the wrong style and you would want something like the Hager 1129 half mortise hinge.
11) My existing hinges are 3-1/2 inch. Can I swap in the 4-1/2 inch Baldwin Estate hinge?
Not without recutting. The Estate 1045 is 4.5 x 4.5 inches, an inch taller and wider than a 3-1/2 inch hinge, so the existing pockets and screw holes will not line up. If you are matching 3-1/2 inch square corner pockets, the Deltana DSB35 3-1/2 x 3-1/2 square hinge or the Emtek 91013 in the same size are the closer swap.
12) My doors take a 3-1/2 inch hinge, not 4-1/2 - what plain bearing square corner options are there?
The Baldwin Estate 1045 is built only at 4-1/2 by 4-1/2. For a 3-1/2 by 3-1/2 square corner plain bearing hinge, the Emtek 91013 is a residential plain bearing pair in plated steel with square corners, and the Schlage Residential S3P1010 is a 3-1/2 by 3-1/2 square corner plain bearing mortise hinge sold in packs of three. The Deltana DSB35 is a 3-1/2 by 3-1/2 square residential hinge sold as a pair.
13) Is the McKinney SQ3331 the same thing as the Baldwin Estate 1045 square corner hinge?
They are both 4-1/2 by 4-1/2 decorative hinges, but they are not the same build. The McKinney SQ3331 is a square barrel 2-knuckle decorative hinge rated standard duty. The Baldwin Estate 1045 is a square corner hinge machined from a solid brass bar, beveled on the inside leaf for a tight fit when closed, at residential strength with a plain bearing, and it is offered in removable and non-removable pin.
14) What is a simpler steel alternative to the Baldwin Estate 1045 for interior residential doors?
The Baldwin Estate 1045 is a solid brass hinge in the Estate Series offered in finishes such as polished brass PVD, oil rubbed bronze and satin black. If you do not need brass or a decorative finish range, the Delaney RH35xx is a bulk steel residential interior hinge at 3-1/2 by 3-1/2 with a 5/8 inch radius corner, sold in pairs, and the Ives 1010RP is a steel plain bearing residential hinge with square corners sold in sets of three. Note the Delaney is a radius corner, so it will not drop into a square corner mortise.
15) My existing mortises are radius corner - what hinge should I order instead of the Baldwin Estate 1045?
The Baldwin Estate 1045 has square corners, so it will leave a gap in a radius corner mortise unless the corners are squared out. For radius prep, the Delaney RH45xx is a 4 inch by 4 inch bulk residential exterior hinge with a 5/8 inch radius, and the Orca Hardware 4014 Series is a 4 by 4 with a 1/4 inch radius corner plain bearing commercial hinge. Confirm which radius your door and frame were routed for before ordering.
16) For a high security or detention opening, is the non-removable pin Baldwin Estate 1045 enough?
The Baldwin Estate 1045 offers a non-removable pin, which addresses pin pulling on an outswing door, but it is a residential strength hinge. For security or detention grade openings, the Deltana DE44R5TA is a 4 by 4 by 5/8 radius security hinge in steel with a tamper resistant build sold as a pair, the Hager 990 STEEL is a full surface prison hinge 3 by 4 with a welded tip, and the BEST BB855 is a heavy duty steel double weight concealed ball bearing prison hinge.
17) Why is one leaf of the Baldwin Estate hinge beveled?
The inside leaf is beveled so the two leaves close tight against each other with no visible gap at the barrel when the door is shut. On a decorative brass hinge that sits in plain view on a front door or a formal interior opening, that closed-position appearance is the reason to pay for a machined hinge over a stamped one.
18) Can I run power through the Baldwin Estate hinge for an electric strike or electrified lock?
No. The 1045 is a plain mechanical brass hinge with no wiring path. Power transfer needs a purpose-built electrified hinge such as the Command Access ETH-BB68 energy transfer hinge, the BEST CECB179-12C electrified hinge with 12-wire quick connect, or, if you also need door position monitoring, the Command Access ETM-BB68 with an integrated door position switch.
19) Do I need to order screws separately for the Baldwin Estate hinges?
No, wood screws are packed with each hinge. They are wood screws, so they suit a wood door and wood jamb. On a hollow metal frame you would need machine screws into tapped holes, which are not supplied here.
20) Which hinges hide the bearing if I do not want a visible bearing knuckle like on standard commercial hinges?
The Baldwin Estate 1045 uses a plain bearing, so there is no bearing knuckle showing at all, and it comes in decorative finishes such as polished nickel PVD and venetian bronze. If you need bearing performance without the exposed bearing, the Ives 3CB1 is a 3-knuckle concealed bearing full mortise hinge rated medium duty, the 3CB1HW is the heavy weight version of the same concealed bearing style, and the Hager 920 is a 2-knuckle full mortise concealed plain bearing hinge in steel.
21) Is there a non-ferrous alternative to the Baldwin Estate 1045 for exterior or coastal doors?
The Baldwin Estate 1045 is manufactured from solid brass extrusions and is machined from a solid brass bar, so the base material is already non-ferrous. Among comparable hinges, the McKinney T2314 is a non-ferrous hinge in standard weight with 5 knuckles, rated medium duty. Steel-base options such as the Delaney RH45xx exterior residential hinge are ferrous by construction.
