Emtek 92033 Heavy Duty Plain Bearing Hinges (Pair), 3-1/2" x 3-1/2" with 5/8" Radius Corners, Plated Steel

Up to 1-3/4 inches. That covers both the 1-3/8 inch interior doors common in homes and the 1-3/4 inch thickness used on entry and heavier doors, so a single hinge size works across a house.

These are residential-duty hinges, plated steel with a plain bearing, and they are meant for homes and light-use openings. For a commercial door, especially one with a closer or in a corridor, step up to a bearing hinge built for it: the Ives 3CB1HW steel heavy weight concealed bearing full mortise hinge, or the Hager BB1168 non-removable pin full mortise ball bearing heavy duty hinge if the opening is an out-swinging exterior door where pin security matters.

The Emtek 92033 is a 3-1/2 inch by 3-1/2 inch plain bearing full mortise hinge with 5/8 inch radius corners, sold in pairs. The Delaney 3-1/2 inch by 3-1/2 inch bulk steel residential interior hinge in the Interior Residential Hinges series matches both the 3-1/2 inch size and the 5/8 inch radius corner, and is also sold as a pair, so it drops into the same mortise without recutting. The Schlage Residential S3P1010 is also a 3.5 inch by 3.5 inch plain bearing mortise hinge, but it has square corners and comes in a pack of three rather than a pair, so it suits a door prepped for square corners and a three-hinge opening.

The Emtek 92033 is prepped as a 3-1/2 inch by 3-1/2 inch hinge with 5/8 inch radius corners, so it will not fill a 4 inch mortise. For a 4 inch opening that keeps the plain bearing action, the Orca Hardware 4 inch by 4 inch square corner plain bearing commercial hinge in the 4040 series and the Orca 4 inch by 4 inch by 1/4 inch radius corner plain bearing hinge in the 4014 series both carry a medium duty rating; pick by whether the jamb is cut square or to a 1/4 inch radius. If the frame is cut to a 5/8 inch radius at 4 inch, the Delaney 4 inch by 4 inch bulk residential exterior hinge is a 5/8 inch radius pair.

The Emtek 92033 is a plain bearing residential hinge sized 3-1/2 inch by 3-1/2 inch and rated for doors up to 1-3/4 inch thick. For heavier leaves, the heavy duty options run larger: the Don-Jo HWBB74545 heavy weight full mortise ball bearing hinge at 4-1/2 inch by 4-1/2 inch, the Don-Jo HWBB75045 at 5 inch by 4-1/2 inch, and the Ives 3CB1HW heavy weight concealed bearing full mortise hinge. Each of those is heavy duty and requires a larger mortise than the 3-1/2 inch prep the Emtek 92033 uses.

The Emtek 92033 is a residential plain bearing hinge in plated steel, sold in pairs with screws. Where an out-swinging or security opening calls for a pin that cannot be pulled, the Deltana CSB45N 4-1/2 inch by 4-1/2 inch square hinge is supplied with a non-removable pin, the Deltana DE44R5TA is a 4 inch by 4 inch 5/8 inch radius steel security hinge sold in pairs, and the Hager BB1168 is a non-removable pin full mortise ball bearing heavy duty hinge. The DE44R5TA shares the 5/8 inch radius corner with the Emtek 92033 but is a 4 inch leaf, so the jamb prep changes.

Eleven finishes, which is what lets them match the knobs and levers already on the doors: Medium Bronze (MB), Tumbled White Bronze (TWB), 613 Satin Bronze Oil-Rubbed, Polished Nickel (US14), 619 Satin Nickel, Pewter (US15A), Flat Black (US19), 625 Bright Chrome, Polished Brass Lifetime (US3), 606 Satin Brass, and French Antique (US7). If you are standardizing a building or a floor of units, order the hinges in the same finish code as the trim and you will not get a near-miss.

Plated steel. The substrate and material are steel, with the finish plated over it, which is why the finish range matches Emtek's brass collection trim even though the hinge itself is not solid brass. For a buyer matching appearance, the plating gets you there; for anyone specifying a non-ferrous hinge for corrosion reasons, this is not it.

The leaf runs 0.118 to 0.126 inches thick. That gauge matters when you are replacing only some hinges on a door: mixing a thicker or thinner leaf into an existing mortise changes how the door sits against the stop and can throw the reveal off. If the door is currently hanging right, match the gauge or swap all the hinges on that opening at once.

Both are 3-1/2 by 3-1/2 inch pairs with 5/8 inch radius corners for residential interior doors, so they drop into the same mortise. The Delaney 3-1/2 by 3-1/2 inch bulk steel residential hinge is the volume option when the hinge just needs to work and nobody is looking at it. The Emtek 92033 exists to be seen, offered in eleven finishes that line up with decorative knob and lever trim. On a rental turn, buy bulk; on a finished space where the hardware is specified, buy the finish match.

The 92033 is the 3-1/2 by 3-1/2 inch size only. For a 4 by 4 inch pocket with the same 5/8 inch radius, ZenSupply carries the Delaney 4 by 4 inch bulk residential exterior hinge in 5/8 inch radius, and the Delaney 4 by 4 inch Castlegate hinge in 5/8 inch radius by square. Heavier exterior doors are usually where the 4 inch leaf shows up, so size to the pocket you already have rather than to the door.

Not on function. The Emtek 92033 is a plain bearing hinge; ball bearing and concealed bearing hinges carry the load on a bearing race instead and are specified where door weight and cycle counts are higher. The Orca Hardware 4-1/2 inch by 4-1/2 inch square corner ball bearing commercial hinge in the 3535 series is a medium duty ball bearing unit, and the Ives 3CB1 is a 3-knuckle concealed bearing full mortise hinge, also medium duty. Both differ from the 92033 in bearing type, and the Orca 3535 and the 4-1/2 inch Deltana and Don-Jo units differ in leaf size as well, so a swap means a different mortise as well as a different bearing.

No. The Emtek 92033 is a non-electronic plain bearing hinge. Openings that need power transferred to an electrified lock or exit device use an energy transfer hinge instead: the Command Access ETH-BB68 is a 5-knuckle heavy duty steel base energy transfer hinge in the ETH 5 series, the ETH-CB70 is a 3-knuckle standard weight version in the ETH 3 series, 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 monitoring, the Command Access ETM-BB68 adds an integrated door position switch.

Both are steel plain bearing residential hinges. The Emtek 92033 is 3-1/2 inch by 3-1/2 inch with 5/8 inch radius corners and is sold in pairs with screws. The Ives 1010RP, in the 1000 series, has square corners and is packed as a set of three, and is rated medium duty. The corner profile is the deciding detail: a jamb routed for a 5/8 inch radius will show a gap around a square corner leaf unless the mortise is squared out by hand.

The Emtek 92033 is a fixed pin plain bearing butt hinge and does not close the door on its own. For a self-closing leaf, the Stanley Security spring hinge is a full mortise square corner unit at 4.5 inch by 4.5 inch on a ferrous steel base, rated heavy duty. For a door that swings in both directions, the BEST DAP-3 is a heavy duty double acting pivot for commercial interior doors, which is a pivot rather than a butt hinge and uses a floor and head prep instead of jamb mortises.

They are not interchangeable. The Emtek 92033 is a 5-knuckle style plain bearing butt hinge with an exposed barrel, offered in finishes such as Flat Black (US19), Polished Nickel (US14) and Polished Brass - Lifetime (US3). The Hager 920 is a full mortise concealed plain bearing hinge with 2-knuckle steel construction and a concealed bearing function, rated medium duty, so the barrel and knuckle appearance differ and it is specified where the bearing is hidden. The Hager 1129 is a half mortise plain bearing commercial hinge at 4-1/2 inch standard weight, which mounts to the frame face rather than into a jamb mortise, so it is not a drop-in for a full mortise prep either.

The Emtek 92033 is sized 3-1/2 inch by 3-1/2 inch and cannot be trimmed down. For a narrower leaf, the Deltana DSB3 is a 3 inch by 3 inch square hinge sold in pairs. If the mortise is 3-1/2 inch but cut square rather than to a radius, the Deltana DSB35 is a 3-1/2 inch by 3-1/2 inch square residential hinge, also sold in pairs, which matches the leaf size of the Emtek 92033 while differing in corner profile.

No handing to specify. Full mortise butt hinges like the 92033 are symmetrical, so the same pair hangs a left-hand or right-hand door; you just flip which leaf goes on the jamb. What you do need to get right is the size, the 5/8 inch radius corner, and the finish.

Screws come in the box with each pair, so a straight hinge swap needs nothing else. The one thing worth adding on an exterior or heavy door is a longer screw through one jamb-leaf hole into the stud framing, which is a job-site practice rather than something supplied with the hinge.

The Emtek 92033 is a residential plain bearing hinge offered across eleven finishes including Medium Bronze (MB), Tumbled White Bronze (TWB), Satin Bronze Oil-Rubbed (613), Satin Nickel (619), Pewter (US15A), Bright Chrome (625) and French Antique (US7), which is what makes it easy to match across interior doors in one scheme. If some openings in the same building carry heavier or commercial-rated doors, the Delaney 4 inch by 4 inch residential hinges for Castlegate come in 5/8 inch radius and square corner pairs, and the McKinney MPB79 MacPro is a 5-knuckle standard weight hinge, so a facility can hold one look on the light doors and step up on the rest.
