Emtek 91013 Residential Plain Bearing Hinges (Pair), 3-1/2" x 3-1/2" with Square Corners, Plated Steel

Yes. The 91013 hinge pair is rated for doors up to 1-3/4 inches thick, which covers both the 1-3/8 inch slabs common on older interior openings and the 1-3/4 inch doors used at entries. The leaf size is 3.5" x 3.5", so the door edge and jamb have to be prepped for that size, not a 4 inch. Door thickness is only half the question though: this is a residential duty hinge, so the slab it hangs should be a residential-weight door, not a commercial solid core with a closer pulling on it.

It depends on the corner of your existing cutout. The 91013 is a 3.5" x 3.5" full mortise hinge with square corners, so it seats cleanly in a square-cut pocket. If your jamb and door were factory machined with rounded corners, which is the other common residential prep, the square leaf will not sit in the pocket without chiseling the corners out. Pull one existing hinge and measure the leaf and look at the corner before ordering. If the prep turns out to be 3-1/2 inch with a 5/8 inch radius, Delaney's 3-1/2" x 3-1/2" residential hinge pair is cut to that radius instead.

Two. The 91013 is sold as a pair and the mounting screws are in the box. Most residential doors hang on three hinges, so for a single door order two packs and keep the fourth hinge as a spare, or plan pairs against your total leaf count on a bigger job. Nothing else ships with it, so if the opening also needs the door and jamb routed, that is site work, not something included in the pack.

No, look elsewhere for that. The 91013 is a residential duty plain bearing hinge, built for house and light interior work, not for the cycle counts a multifamily corridor or an office suite door sees. For the same 3-1/2 inch size class in a commercial build, Orca Hardware's 3.5" x 3.5" plain bearing commercial hinge is medium duty (note it has 1/4 inch radius corners, not square). If the opening has a closer on it or gets constant traffic, go to a bearing hinge: the Ives 3CB1 concealed bearing full mortise is medium duty commercial.

The Emtek 91013 is a 3-1/2" x 3-1/2" plain bearing hinge with square corners in plated steel, sold in pairs with screws. Two peers match that same combination. The Schlage Residential S3P1010 is a 3.5" x 3.5" square corner plain bearing mortise hinge rated medium duty, packed three to a box. The Ives 1010RP is a steel plain bearing residential hinge with square corners, also medium duty, sold as a set of three. Both seat in the same square corner mortise the 91013 uses; the working difference is the pack, three hinges to a box against the 91013's pair.

Yes. The Deltana DSB35 is a 3-1/2" x 3-1/2" square residential hinge sold as a pair, matching the Emtek 91013 on leaf size, square corner and pack count. If the door or stile calls for a smaller leaf, Deltana also builds the DSB3 as a 3" x 3" square hinge sold as a pair, which needs a shorter mortise than the 91013's 3-1/2" cut.

Only if the mortise is recut. The Emtek 91013 has square corners. The Delaney 3-1/2" x 3-1/2" bulk steel residential interior hinge is the same 3-1/2" leaf but cut with a 5/8" radius, and the Orca Hardware 3.5" x 3.5" plain bearing commercial hinge is cut with a 1/4" radius corner. A radius leaf dropped into a square pocket leaves open corners, and a square leaf will not seat in a radius pocket without chiseling it out. Confirm the corner geometry already routed into the door and jamb before ordering either one.

The Emtek 91013 is a residential duty plain bearing hinge. On an opening that cycles like a commercial door, the Ives 3CB1 is a 3-knuckle concealed bearing full mortise hinge rated medium duty, and the Ives 3CB1HW is the heavy weight concealed bearing full mortise hinge rated heavy duty. Concealed bearing hinges ride on a bearing race between the knuckles rather than on the plain knuckle faces the 91013 uses.

Specify a non-removable pin hinge for that opening. The Deltana CSB45N is a 4-1/2" x 4-1/2" square hinge sold as a pair with a non-removable pin, so it keeps the square corner geometry of the Emtek 91013 on a larger leaf. The Hager BB1168 NRP is a non-removable pin full mortise ball bearing hinge rated heavy duty. Deltana also builds the DE44R5TA, a 4" x 4" steel security hinge with a 5/8" radius corner, sold as a pair, which needs a radius mortise rather than the square pocket the 91013 sits in.

Plain bearing means the knuckles ride directly against each other with no bearing race stacked between them. Fewer parts, thinner barrel, quieter looking hinge, and it holds up fine under residential loads, which is what the 91013 is built for at 0.084 to 0.090 inch leaf thickness and residential duty. A bearing hinge puts a race between the knuckles so the weight rides on the bearing instead of the metal faces, which is what keeps a heavy or high-cycle door from sagging and squealing. Rule of thumb: light interior and residential entry doors, plain bearing is enough. Heavy slab, closer, or constant traffic, go bearing, such as Orca's 4-1/2 inch square corner ball bearing commercial hinge or the Ives 3CB1HW heavy weight concealed bearing.

Route to the leaf thickness, which on the 91013 runs 0.084 to 0.090 inch. Cut the pocket to that depth in both the door edge and the jamb so the leaf sits flush with the surface; too shallow and the door will not close against the stop, too deep and it binds hinge-bound at the barrel. This is a full mortise hinge, so both leaves get recessed, one into the door and one into the frame.

The 91013 hinge pair measures 3.5" x 3.5" with square corners. That is the smaller of the two sizes you see on residential openings; heavier or wider slabs are usually hung on 4 inch. If your prep is 4 inch square corner, Orca Hardware's 4" x 4" square corner plain bearing commercial hinge is the same bearing type in that size, and Delaney's 4" x 4" residential pair comes 5/8 inch radius on one leaf by square on the other.

Three close substitutes, and the pack count is the thing that trips people up. Schlage Residential S3P1010 is a 3.5" x 3.5" square corner plain bearing mortise hinge sold as a pack of three, so one pack hangs one door. Ives 1010RP is a steel plain bearing residential hinge with square corners, also a set of three. Deltana DSB35 is a 3-1/2" x 3-1/2" square residential hinge sold as a pair, same as the 91013, so you order two packs per three-hinge door. Match the finish on whichever you pick to the rest of the door trim, since these all publish different finish ranges.

The Emtek 91013 is built in eleven finishes: Medium Bronze, Tumbled White Bronze, 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, so the hinge can be run to the same finish code as the knobs and levers on the same door. Among the commercial ball bearing peers, the Don-Jo HWBB74545 at 4-1/2" x 4-1/2" and the HWBB84545 at the same size are cataloged in satin chrome.

The Emtek 91013 is a non-electronic hinge, so power transfer has to come from an energy transfer hinge. The Command Access ETH-CB70 is a 3-knuckle standard weight steel base energy transfer hinge rated medium duty, and the ETH-BB68 is the 5-knuckle heavy duty steel base version. If the opening also has to report door position, the Command Access ETM-CB70 adds door position sensing on a 3-knuckle steel base and the ETM-BB68 adds an integrated door position switch on a heavy duty leaf. The BEST CECB179-12C is a steel full mortise concealed bearing electrified hinge with a 12-wire quick connect, rated medium duty.

The Orca Hardware 4" x 4" square corner plain bearing commercial hinge keeps the same plain bearing action and square corner as the Emtek 91013 on a 4" leaf, and is rated medium duty. Delaney's 4" x 4" commercial hinge is also square corner but runs ball bearings instead of plain. Stepping up again, the Orca Hardware 4-1/2" x 4-1/2" square corner ball bearing commercial hinge is likewise medium duty. All three need a longer and wider mortise than the 91013's 3-1/2" x 3-1/2" cut.

Move to a heavy weight ball bearing hinge on a larger leaf. The Don-Jo HWBB74545 is a heavy weight full mortise ball bearing hinge at 4-1/2" x 4-1/2" in satin chrome, rated heavy duty. The Don-Jo HWBB75045 is the same heavy weight full mortise ball bearing hinge in a 5" x 4-1/2" steel leaf, and the HWBB85045 is a 5" x 4-1/2" brass version, both heavy duty in satin chrome. Each of these takes a taller mortise than the Emtek 91013's 3-1/2" x 3-1/2" leaf, so the door edge and jamb have to be routed for the larger size.

A spring hinge does that job. 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 keeps the square corner prep the Emtek 91013 uses but on a larger leaf, and the spring inside the barrel returns the door rather than leaving it wherever it was pushed. The 91013 is a plain bearing butt hinge with no closing action of its own.

No, the door prep is different. The Emtek 91013 is a full mortise hinge, so both leaves recess into the door edge and the jamb. The Hager 1129 is a half mortise plain bearing commercial hinge, 4-1/2" standard weight steel, which mortises into the door and applies to the face of the frame instead. They share the plain bearing action but not the mounting. The Hager 990 STEEL is further off again, a full surface prison hinge at 3" x 4" with a welded tip, applied to the faces of both door and frame.

The Emtek 91013 is built on a steel substrate with a plated steel finish. Where a non-ferrous base is wanted instead, the McKinney T2314 is a non-ferrous standard weight hinge with 5 knuckles, rated medium duty. It is the base material that differs, not the mounting style; both are full mortise butt hinges that recess into the door edge and jamb.

They are a different class of hardware, not a heavier version of the same part. The BEST BB855 is a heavy-duty steel double weight concealed ball bearing prison hinge in the detention hardware family, and the Stanley Security double weight prison hinge is a 5" by 6" leaf furnished with no holes and not swaged, so it is drilled and set up at fabrication rather than screwed to an existing door. The Hager 990 STEEL is a full surface prison hinge at 3" x 4" with a welded tip. The Emtek 91013 is a residential duty full mortise hinge sold in pairs with screws, prepped for a standard 3-1/2" square mortise.

That calls for a pivot rather than a butt hinge. The BEST DAP-3 is a heavy duty double acting pivot for commercial interior doors, which lets the leaf swing in both directions and carries the door on top and bottom pivot points instead of on hinges at the jamb. The Emtek 91013 is a full mortise butt hinge that recesses into the door edge and jamb and swings one way only.

Two peers change the barrel rather than the prep. The McKinney SQ3331 is a square barrel 2-knuckle decorative hinge at 4-1/2" by 4-1/2", rated standard duty, so the barrel reads as a square column at the door edge. The Hager 920 is a full mortise concealed plain bearing hinge with 2-knuckle steel construction, rated medium duty, which shortens the visible knuckle stack. The Emtek 91013 keeps a plain bearing barrel in a square cornered 3-1/2" leaf and is offered in eleven finishes to sit with the rest of the trim.

Some lines split them. Delaney catalogs a 3-1/2" x 3-1/2" bulk steel residential hinge for interior doors and a 4" x 4" bulk residential hinge for exterior doors, both with a 5/8" radius corner, plus a 4" x 4" Castlegate residential hinge sold as a pair. The Emtek 91013 is a residential duty hinge at 3-1/2" x 3-1/2", and its square corner means it will not swap directly with any of the 5/8" radius Delaney leaves without changing the mortise.
