Emtek 94013 Heavy Duty Ball Bearing Hinges (Pair), 3-1/2" x 3-1/2" with Square Corners, Plated Steel

No. The Emtek 94013 is a square corner hinge, so it wants a chiseled pocket with sharp corners. Drop it into a router-cut mortise with a radiused corner and the leaf sits proud at the corners unless you square the pocket off with a chisel. If you would rather match what is already cut, buy a radius hinge in the same 3-1/2 by 3-1/2 size: Delaney lists a 3-1/2 by 3-1/2 residential hinge with a 5/8 inch radius, and Orca a 3.5 by 3.5 commercial hinge with a 1/4 inch radius corner. Look at one of your existing hinges first, 5/8 inch radius is the usual builder-door corner and 1/4 inch turns up on commercial prep.

Doors up to 1-3/4 inches thick. That covers the 1-3/8 inch interior doors in most older homes as well as standard 1-3/4 inch doors, so the same 94013 works on bedroom and closet doors and on a 1-3/4 inch entry or solid core slab. Anything thicker than 1-3/4 inches is outside what the hinge is rated for.

Not without recutting the door. The 94013 measures 3-1/2 by 3-1/2 inches, so it leaves a half inch of open mortise at each hinge if you put it into a 4 inch pocket. For a 4 inch square corner replacement, Delaney sells a 4 by 4 commercial ball bearing hinge with square corners and Orca a 4 by 4 square corner plain bearing hinge. Measure an existing leaf top to bottom before ordering, 3-1/2 and 4 inch are the two sizes that get mixed up most often.

Emtek classes the 94013 as residential hardware, and at 3-1/2 by 3-1/2 inches it is sized for residential slabs rather than the 4-1/2 inch prep most commercial frames are cut for. For a commercial opening, look at hinges built and sized for it: Orca lists a 4-1/2 by 4-1/2 square corner ball bearing commercial hinge, Ives the 3CB1HW steel heavy weight concealed bearing full mortise hinge, and Don-Jo the HWBB84545 heavy weight full mortise ball bearing hinge at 4-1/2 by 4-1/2 in satin chrome. Apartment interiors inside the unit are a different matter, that is where the 94013 belongs.

The Emtek 94013 is a 3-1/2" x 3-1/2" hinge with square corners, sold in pairs with screws. Two peers share that mortise footprint. The Deltana DSB35 is a 3-1/2" x 3-1/2" square hinge for residential openings, also sold as a pair, so it seats in the same square-cornered pocket without recutting the door edge or jamb. The Schlage Residential S3P1010 is a 3.5" x 3.5" square corner mortise hinge in a pack of three, which covers a standard interior door in one order rather than a pair plus a single. The S3P1010 is a plain bearing hinge, while the Emtek 94013 runs on ball bearings, so the two differ in how the leaf carries the load even though the cutout is the same.

The Emtek 94013 has square corners, which means the corners of the mortise have to be chiseled square. For a pocket that is already routed with a rounded corner, match the radius: the Delaney 3-1/2" x 3-1/2" bulk steel residential interior hinge is a 5/8" radius hinge sold in pairs, and the Orca Hardware 3.5" x 3.5" commercial hinge is a 1/4" radius corner plain bearing hinge rated medium duty. The two radii are not interchangeable with each other, so measure the corner of an existing mortise before ordering. Radius corner leaves drop straight into a router-cut pocket with no chisel work.

Going up in leaf size means a deeper mortise in both the door edge and the jamb, so it is not a swap on an existing prep. The Delaney CH401X is a 4" x 4" commercial ball bearing hinge with a square corner, which keeps both the ball bearing action and the square corner of the Emtek 94013 while adding half an inch of leaf in each direction. The Orca Hardware COM4040 is a 4" x 4" square corner commercial hinge with a plain bearing, rated medium duty. If the opening steps up again, the Orca COM3535 is a 4-1/2" x 4-1/2" square corner ball bearing commercial hinge, medium duty.

Handing does not come into it. A full mortise butt hinge like the 94013 is symmetrical, the same hinge hangs a left hand or right hand door, and which way the pin points is set by how you mount it, not by what you order. The only thing you specify is finish, and there are eleven of those.

Ball bearings sit between the knuckles and carry the door's weight on a rolling surface, which is what you want on a heavier slab or a door that gets opened all day, a primary bedroom, a bathroom, a unit entry. The Emtek 94013 is a ball bearing hinge in the 3-1/2 by 3-1/2 size. On a hollow core closet or pantry door that swings a few times a week, a plain bearing hinge is the normal choice and costs less to standardize on: Schlage Residential lists a 3.5 by 3.5 square corner plain bearing hinge in packs of three, and Ives the 1010RP steel plain bearing residential hinge with square corners in sets of three.

No, the 94013 is a plain mechanical hinge with no wire transfer through the barrel. Running power to an electrified lock or an exit device means an energy transfer hinge: Command Access lists the ETH-CB70, a 3 knuckle standard weight steel base energy transfer hinge, and the ETH-BB68, a 5 knuckle heavy duty version, while BEST offers the CECB179-12C steel full mortise concealed bearing electrified hinge with a 12-wire quick connect. If you also need to know whether the door is open, Command Access builds the ETM-CB70 and ETM-BB68 with a door position switch in the same hinge.

Eleven finishes: 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). The finish code rides on the model number, so Medium Bronze is 94013MB and Tumbled White Bronze is 94013TWB. Order the hinges by the same finish name you used on the knobs or levers, since these are Emtek's own finish designations rather than generic color names.

Leaf thickness runs 0.118 to 0.126 inches. That is the number to check against the pocket depth on the door and jamb you are replacing hinges in: if the old hinge was thinner, the new leaf stands proud and the door binds against the stop, and the fix is to pare the mortise a hair deeper rather than shim it. Same size and corner style as what came out, a square corner 3-1/2 by 3-1/2, and the swap is a screw-for-screw job with the screws in the pack.

The Emtek 94013 is a ball bearing hinge in a 3-1/2" x 3-1/2" square corner size. If a plain bearing knuckle is what the job calls for, the Schlage Residential S3P1010 is a 3.5" x 3.5" square corner plain bearing mortise hinge rated medium duty and packed three to a box, and the Ives 1010RP is a steel plain bearing residential hinge with square corners, also medium duty, sold as a set of three. In a ball bearing hinge the leaves ride on bearing races between the knuckles; in a plain bearing hinge the knuckles bear directly on each other. Both of these keep the square corner, so the mortise prep does not change.

The Emtek 94013 is catalogued for residential use in a 3-1/2" x 3-1/2" size. For a commercial door cycling all day, the Don-Jo HWBB84545 is a heavy weight full mortise ball bearing hinge, 4-1/2" x 4-1/2", in satin chrome and rated heavy duty; the Don-Jo HWBB75045 is the same heavy weight ball bearing pattern in a 5" x 4-1/2" steel leaf for a wider door. The Ives 3CB1HW is a heavy weight steel hinge with three knuckles and a concealed bearing, also heavy duty, where a flush knuckle profile is wanted. All three call for a larger mortise than a 3-1/2 inch hinge.

A spring hinge does that job. The Stanley Security 2060R is a full mortise spring hinge with a square corner in 4-1/2" x 4-1/2", built on a ferrous steel base and rated heavy duty, so it mortises like an ordinary hinge but carries a spring that returns the door. The Emtek 94013 is a free-swinging ball bearing hinge in 3-1/2" x 3-1/2" with square corners and holds the door wherever it is left. On a self-closing opening the spring hinges usually replace the top and bottom hinge while a standard hinge stays in the middle, so both types can appear on one door.

Both leaves of the Emtek 94013 mortise in, one into the door edge and one into the jamb. Where the frame cannot be cut, the Hager 1129 is a half mortise plain bearing commercial hinge in 4-1/2", standard weight steel, which mortises into the door and applies to the face of the frame. The Hager 990 STEEL is a full surface prison hinge, 3" x 4", heavy duty with a welded tip, and mounts on the faces of both the door and the frame with no mortise at all. Surface and half mortise leaves sit proud of the door face, which changes the reveal and the clearance at the stop.

It will not. The 94013 is a standard ball bearing butt hinge with no spring in it, so the door stays where you leave it. For a door that has to self close, a garage-to-house door or a laundry, you need a spring hinge: Stanley Security builds a full mortise spring hinge with square corners at 4-1/2 by 4-1/2 in a ferrous steel base. Spring hinges are usually mixed with regular hinges on the same door rather than used at every position.

It is what the bearing looks like from the hallway. The Emtek 94013 carries ball bearings in a five knuckle style barrel with square corners. A concealed bearing hinge hides the bearing inside the knuckle for an unbroken barrel: the Ives 3CB1 is a steel three knuckle concealed bearing full mortise hinge rated medium duty, the Ives 3CB1-B is the same three knuckle concealed bearing full mortise pattern in a medium duty commercial grade, and the Hager 920 is a full mortise concealed plain bearing hinge with two knuckle steel construction, medium duty. Both types mortise the same way; the knuckle count and barrel appearance are what change on the finished door.

Only when the door has to swing both directions. The BEST DAP-3 is a heavy duty double acting pivot for commercial interior doors, and it mounts at the top and bottom of the door rather than along the edge, so the floor and header take the prep and the door edge stays uncut. That is a different opening from the one a butt hinge serves. The Emtek 94013 is a 3-1/2" x 3-1/2" full mortise butt hinge with square corners, hung on the door edge and jamb for a single direction of swing. Switching between the two is a change to the door and frame prep, not a hardware swap.

The McKinney SQ3331 is a decorative hinge with a square barrel and two knuckles in 4-1/2" x 4-1/2", rated standard duty, and it reads as a squared column at the jamb instead of a stack of round knuckles. The Emtek 94013 pairs square corners with a plated steel finish in a 3-1/2" x 3-1/2" size and offers the barrel in finishes from Flat Black and Medium Bronze through Polished Nickel and Polished Brass, so the barrel can be matched to the levers without changing the hinge style. The SQ3331 is the larger leaf of the two and needs a 4-1/2 inch mortise.
