Emtek 92025 Heavy Duty Plain Bearing Hinges (Pair), 4-1/2" x 4-1/2" with 1/4" Radius Corners, Plated Steel

The Emtek 92025 is a 4-1/2 x 4-1/2 inch full mortise hinge with 1/4 inch radius corners, so it drops into an existing 4-1/2 inch mortise only if that mortise was routed with 1/4 inch radius corners. Most factory-prepped doors and jambs use either 1/4 inch or 5/8 inch radius, and a 5/8 inch pocket will leave a visible gap at the corners while a square-corner pocket needs the corners chiseled. Check the corner radius on the hinge you are pulling off before you order.

No. The 92025 is a plain bearing residential hinge with no security feature called out, so on an out-swinging exterior door the pin is reachable. Go to a non-removable pin or security hinge instead: the Deltana CSB45N is a 4-1/2 x 4-1/2 pair with a non-removable pin, the Deltana DE44R5TA is a 4 x 4 security hinge with a 5/8 inch radius, and the Hager BB1168 NRP is a heavy duty full mortise ball bearing hinge with a non-removable pin.

The 92025 is a residential plain bearing hinge. For a commercial opening carrying the same plain bearing function, the Orca Hardware 4040 Series is a 4 inch by 4 inch square corner plain bearing commercial hinge and the Orca Hardware 4014 Series is the 1/4 inch radius version at the same size, both rated medium duty. Where the opening needs heavy duty, the Don-Jo HWBB84545 is a heavy weight full mortise ball bearing hinge at 4-1/2 inch by 4-1/2 inch, and the Hager BB1168 is a heavy duty full mortise ball bearing hinge with a non-removable pin for outswing exterior doors.

No. The 92025 is a mechanical plain bearing hinge with no electrical provision. To transfer power through the hinge, the Command Access ETH-BB68 is a 5-knuckle heavy duty steel base energy transfer hinge and the ETH-CB70 is the 3-knuckle standard weight version. If you also need door position monitoring, the Command Access ETM-BB68 is an energy transfer hinge with an integrated door position switch. The BEST CECB179-12C is a steel full mortise concealed bearing electrified hinge with a 12-wire quick connect.

Sold as a pair with screws included. Two hinges is enough for a light interior door, but a typical 1-3/4 inch exterior or solid core door wants three per leaf, so order two pairs and you have a spare hinge, or plan the count against the door before you check out.

Leaf gauge runs 0.118 to 0.126 inches on the 92025. That matters when you are swapping into an existing mortise: a thinner leaf than what came out leaves the door sitting slightly proud of the stop, and a thicker one can bind the door against the jamb until the pocket is deepened.

Eleven finishes on the 92025: 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). Those are Emtek's own finish codes, so they line up with Emtek knobsets, leversets and trim carrying the same code, which is the usual reason people buy the hinge in a decorative finish rather than plated steel primed to disappear.

Steel, plated. The 92025 is a plated steel hinge, not solid brass, even though the finish codes match Emtek's brass collection. If you need a non-ferrous hinge for a coastal or wet location, the McKinney T2314 is a non-ferrous 5-knuckle standard weight hinge.

No handing to specify. The 92025 is a standard full mortise butt hinge with a removable pin, so a single pair works on a left hand or right hand door. You only start dealing with handing on hinges when you move to a spring hinge, an electrified hinge, or a security hinge, where the Stanley Security concealed conductor architectural hinge, for example, is ordered left-handed as a distinct part.

A plain bearing hinge like the Emtek 92025 has no bearing race between the knuckles, which keeps the barrel slimmer and cheaper and is what most residential interior and light entry doors run. A ball bearing or concealed bearing hinge carries a heavier leaf and a lot more cycles without wearing the knuckles oval, which is why they go on commercial and high-traffic openings. Rule of thumb: hollow core and standard solid core interior doors on a house, plain bearing is enough. Heavy solid core, tall doors, doors with a closer on them, or anything in a lobby or corridor, spend the money on bearings.

No. The Emtek 92025 uses a plain bearing. A concealed bearing hinge hides the bearing inside the knuckle instead: the Ives 3CB1 is a 3-knuckle concealed bearing full mortise hinge in medium duty, the Ives 3CB1HW is the heavy weight steel version, and the Hager 920 is a 2-knuckle full mortise concealed bearing hinge. They are all full mortise like the 92025, so the mortise prep is the same family of cut, but the bearing type and knuckle count are different and the barrel appearance will not match a plain bearing hinge on adjacent doors.

The Emtek 92025 is a residential plain bearing hinge offered in eleven finishes including Flat Black US19, Polished Nickel US14, and Polished Brass Lifetime US3. If the finish selection is not what is driving the order, the Ives 1010RP is a steel plain bearing residential hinge with square corners sold in sets of three, and the Schlage Residential S3P1010 is a 3-1/2 inch by 3-1/2 inch square corner plain bearing mortise hinge in packs of three. Both are square corner rather than the 92025's 1/4 inch radius, and both are packed in threes rather than pairs, which matters when you are counting hinges per door leaf.

No. Both are plain bearing, but the Hager 1129 is a half mortise commercial hinge in 4-1/2 inch standard weight steel, meaning one leaf mortises into the door and the other surface-applies to the frame. The Emtek 92025 is full mortise, cut into both the door and the jamb. The prep is different, so they are not interchangeable on an existing opening even at matching leaf size.

The Emtek 92025 is sold in pairs with screws and is cut for 1/4 inch radius corners. Where the existing prep is a 5/8 inch radius, the Delaney RH45xx is a 4 inch by 4 inch bulk residential exterior hinge pair with a 5/8 inch radius, the Delaney RH35xx is the 3-1/2 inch by 3-1/2 inch interior pair, and the Delaney RH40xx is a 4 inch by 4 inch residential pair in 5/8 inch radius by square. All three are sold in pairs, so hinge counts per door carry over directly.

No. The 92025 is a residential plain bearing hinge. Detention and high-security openings use a different class of hinge: the BEST BB855 is a heavy-duty steel double weight concealed ball bearing prison hinge, the Stanley Security BB855 is a double weight prison hinge at 5 inch by 6 inch furnished with no holes and not swaged, and the Hager 990 STEEL is a full surface prison hinge at 3 inch by 4 inch with a welded tip. Those mount and prep differently from a full mortise residential pair.

The 92025 is a full mortise hinge and swings one direction only. A door that needs to swing both ways takes a pivot rather than a hinge: the BEST DAP-3 is a heavy duty double acting pivot for commercial interior doors. The BEST CB1969R is a concealed bearing heavy weight pivot-reinforced hinge for heavy leaves that still swing one way.
