Baldwin Reserve 1035 Square Corner Hinge 3.5"x 3.5"

Pin style is the second thing you pick after finish, and it decides security. A removable pin lets you drive the pin out and lift the door off without unscrewing anything, which is what you want on interior doors you will pull for painting or moving furniture. A non-removable pin (NRP) is set so it cannot be driven out from the hinge side, which matters on any outswing door where the barrel is on the exterior, since otherwise someone can pull the pin and take the door off its hinges. Both pin styles are offered in all 13 finishes on the 1035.

Screws are in the box. Each 1035 hinge is poly-bagged with 6 #10 flat head Phillips wood screws, packed one hinge per box. That last part is the detail that trips up orders: this is sold as a single hinge, not a pair and not a set of three, so a standard door needing three hinges is a quantity of three.

Not without recutting. The 1035 is 3.5 x 3.5 inches, so it leaves a half inch of empty mortise at each pocket on a door prepped for 4 inch hinges, and the screw holes will not line up. Either fill and recut, or buy the 4 inch size. Square corner 4 inch alternatives include the Orca Hardware 4040 Series 4 x 4 square corner plain bearing commercial hinge and the Delaney CH401X 4 x 4 commercial ball bearing square corner hinge.

The Baldwin Reserve 1035 is a mechanical 3.5" x 3.5" square corner hinge with stainless steel rust-proof pins and no provision for wiring. When current has to cross the opening, the hinge itself carries the conductors: the Command Access ETH-CB70 is a 3-knuckle standard weight steel base energy transfer hinge at medium duty, the ETH-BB68 is a 5-knuckle heavy duty steel base energy transfer hinge, and the BEST CECB179-12C is a steel full mortise concealed bearing electrified hinge with a 12-wire quick connect at medium duty. If the opening also needs door position monitoring, the Command Access ETM-CB70 adds door position sensing on a 3-knuckle steel base and the ETM-BB68 integrates a door position switch at heavy duty. These are electrified builds, not a finish variation on the 1035.

The Baldwin Reserve 1035 is a 3.5" x 3.5" square corner hinge rated residential. For an opening that sees heavier cycling at the same size and corner style, the Emtek 94013 is a heavy duty ball bearing hinge, 3-1/2" x 3-1/2" with square corners in plated steel, sold as a pair. The Emtek 92013 is a heavy duty plain bearing hinge in the same 3-1/2" x 3-1/2" square corner size, and the Emtek 96213 is a heavy duty hinge at 3-1/2" x 3-1/2" with square corners. All three keep the same mortise footprint as the 1035, so a swap to heavy duty does not require rework of the door or frame prep.

The Baldwin Reserve 1035 is a 3.5" x 3.5" square corner full mortise hinge, so anything cut for a different leaf size or corner shape needs a new mortise. The Deltana DSB3 is a 3" x 3" square hinge sold in pairs and the Deltana DSB35 is a 3-1/2" x 3-1/2" square residential hinge - only the DSB35 shares the 1035 footprint. The Orca Hardware 3514 Series is 3.5" x 3.5" but with a 1/4" radius corner rather than square, and the Orca 4040 Series is a 4" x 4" square corner plain bearing commercial hinge. The Emtek 91013 at 3-1/2" x 3-1/2" square corners is a true size match; the Delaney CH401X commercial ball bearing square corner hinge is 4" x 4" and is not. Confirm both leaf dimension and corner radius before ordering a substitute.

The Baldwin Reserve 1035 in 3.5" x 3.5" is ordered with either a removable pin or a non-removable pin, so the NRP option is available in each of its finishes including 190 Satin Black. In larger sizes, the Deltana CSB45N is a 4-1/2" x 4-1/2" square hinge sold in pairs with a non-removable pin, and the Hager BB1168 is a non-removable pin full mortise ball bearing hinge at heavy duty. The Deltana DE44R5TA is a 4" x 4" x 5/8" radius security hinge in steel with tamper-resistant construction. For an out-swinging exterior opening that already has a 3-1/2 inch square mortise, the 1035 NRP holds the size; the Deltana and Hager options apply where the door is prepped for a 4-inch or larger leaf.

Thirteen, and they are Baldwin's standard Reserve numbers so they match the levers and knobs in the same collection: 003 Polished Brass PVD, 044 Satin Brass PVD, 050 Satin Brass Black, 055 Polished Nickel PVD, 056 Lifetime PVD Satin Nickel, 060 Satin Brass and Brown, 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. If you are matching existing Baldwin hardware in a house, order by that finish number rather than by the finish name, since the names repeat across brands and the numbers do not.

For a decorative match to Baldwin Reserve trim, yes. For volume turnover work where nobody is looking at the hinge, there are cheaper 3-1/2 x 3-1/2 square corner options: the Schlage Residential S3P1010 square corner plain bearing mortise hinges ship in packs of three, which covers one door per pack, and the Emtek 91013 residential plain bearing square corner hinges in plated steel come as a pair. The Baldwin sells on finish depth and the solid brass look, not on cost per door.

That is what it is for. The 1035 is part of the Reserve Series and carries the same Baldwin finish codes used across that collection, so a 102 Oil Rubbed Bronze hinge is the same 102 as the lever. Order by number, not by name, and the hinge, lever, and rosette read as one set on the door.

The Baldwin Reserve 1035 is a 3.5" x 3.5" square corner full mortise hinge rated residential, supplied with six #10 flat head Phillips wood screws for a wood door and frame. Commercial openings are served by different builds in the same square corner family: the Orca Hardware 3535 Series is a 4-1/2" x 4-1/2" square corner ball bearing commercial hinge at medium duty, the Orca 4040 Series is a 4" x 4" square corner plain bearing commercial hinge at medium duty, and the Ives 3CB1 is a 3-knuckle concealed bearing full mortise hinge at medium duty. The Delaney CH401X is a 4" x 4" commercial ball bearing square corner hinge. All of those are larger leaves or bearing designs meant for hollow metal and heavier wood doors, so they call for their own mortise prep rather than the 1035's 3-1/2 inch pocket.

The Baldwin Reserve 1035 is a 3.5" x 3.5" square corner hinge offered in PVD and plated decorative finishes such as 003 Polished Brass PVD and 102 Oil Rubbed Bronze. Where the hinge will not be seen, the Delaney 3-1/2" x 3-1/2" bulk steel residential interior hinge (DLY-RH35xx) is the same 3-1/2 inch size sold in pairs from the Interior Residential Hinges series, and the Ives 1010RP is a steel plain bearing residential hinge with square corners sold in sets of three at medium duty. One difference matters for prep: the Delaney bulk hinge has a 5/8" radius corner rather than the square corner of the 1035, so it suits a router-cut radius mortise, while the Ives 1010RP keeps square corners and matches a chiseled square mortise.

The Baldwin Reserve 1035 is a standard 3.5" x 3.5" square corner full mortise hinge with removable or non-removable pin and no closing mechanism. Where the door has to self-close, the Stanley Security 2060R is a full mortise spring hinge with square corners at 4.5" x 4.5" on a ferrous steel base, rated heavy duty. It shares the square corner and full mortise style of the 1035 but is a larger 4-1/2 inch leaf, so the frame and door need prep for that size rather than the 3-1/2 inch pocket.

Both are chosen partly for how they look on the door. The Baldwin Reserve 1035 is a 3.5" x 3.5" square corner hinge from the Reserve Series, beveled on the inside leaf for a tight fit when closed, offered in finishes including 055 Polished Nickel PVD and 402 Distressed Oil Rubbed Bronze. The McKinney SQ3331 is a square barrel 2-knuckle decorative hinge at 4-1/2" by 4-1/2", rated standard duty. The visual difference is the barrel: the SQ3331 uses a square barrel and two knuckles, while the 1035 carries a conventional round barrel with a stainless steel pin. The size difference decides the substitution - the SQ3331 needs a 4-1/2 inch mortise.

It depends on whether the hinges are seen. The Baldwin Reserve 1035 is packed one per box, each hinge poly-bagged with fasteners, in 3.5" x 3.5" square corner and finishes from 044 Satin Brass PVD to 260 Polished Chrome, so a unit can be finished to match the rest of the trim hardware. For volume interior work, the Delaney bulk steel residential interior hinge is 3-1/2" x 3-1/2" sold by the pair with a 5/8" radius corner, and the Delaney exterior bulk hinge (DLY-RH45xx) is 4" x 4" with a 5/8" radius. Both Delaney bulk options are radius corner, so they suit doors already routed with a radius mortise, while the 1035 matches a square-cut pocket at 3-1/2 inches.

The Baldwin Reserve 1035 is a residential-rated 3.5" x 3.5" hinge with a .125" leaf thickness. For heavy leaves and abuse-prone openings, the Don-Jo HWBB74545 is a heavy weight full mortise ball bearing hinge at 4-1/2" x 4-1/2" in satin chrome and the Don-Jo HWBB75045 is a heavy weight full mortise ball bearing hinge at 5" x 4-1/2" in steel with satin chrome finish, both heavy duty. The Ives 3CB1HW is a steel heavy weight concealed bearing full mortise hinge with 3 knuckles, and for detention or maximum-security work the BEST BB855 is a heavy-duty steel double weight concealed ball bearing prison hinge. These carry far larger leaves than the 1035, so the door and frame must be prepped to their size.

The Baldwin Reserve 1035 is a 3.5" x 3.5" square corner hinge machined for precise installation with stainless steel, rust-proof pins. For a bearing hinge in the same 3-1/2 inch square corner size, the Emtek 94013 is a heavy duty ball bearing hinge, 3-1/2" x 3-1/2" with square corners in plated steel, sold as a pair. Stepping up in size, the Orca Hardware 3535 Series is a 4-1/2" x 4-1/2" square corner ball bearing commercial hinge at medium duty and the Delaney CH401X is a 4" x 4" commercial ball bearing hinge with square corners. Only the Emtek 94013 keeps the 1035's 3-1/2 inch mortise.

The pins are stainless steel and rust-proof, which is the part of a hinge that usually stains a jamb first. The plated and PVD finishes on the leaves, like 056 Lifetime PVD Satin Nickel and 003 Polished Brass PVD, are the more durable coatings in the range. For an outswing exterior door, order the non-removable pin version so the pin cannot be driven out from outside.
