Emtek 94025 Heavy Duty Ball Bearing Hinges (Pair), 4-1/2" x 4-1/2" with 1/4" Radius Corners, Plated Steel

Emtek lists the 94025 as a residential hinge. It is plated steel with a decorative finish, built to match Emtek trim on a house or a high-end multi-family unit. For a commercial opening where a spec calls for a rated architectural hinge, look at something like the Hager BB1168 full mortise heavy duty ball bearing hinge or the Ives 3CB1HW heavy weight concealed bearing hinge instead.

Corner profile is the only thing that decides it. The 94025 has 1/4 inch radius corners, which is what a router with a hinge template cuts. A square corner hinge, such as the Orca Hardware 4-1/2 by 4-1/2 square corner ball bearing hinge or the Deltana CSB45N 4-1/2 inch square hinge, suits mortises that were chiseled square. Match whichever your existing pockets already are.

If the door swings out, the hinge pins are accessible from the exterior, and a standard pin can be driven out. The Emtek 94025 is a standard ball bearing hinge without an NRP feature. For that opening look at a non-removable pin option such as the Hager BB1168 NRP full mortise ball bearing hinge or the Deltana CSB45N 4-1/2 inch square hinge with non-removable pin.

The Emtek 94025 is a 4-1/2 inch by 4-1/2 inch ball bearing hinge with 1/4 inch radius corners. If the existing mortises in your jambs are cut square, the Orca Hardware 3535 Series is a 4-1/2 inch by 4-1/2 inch square corner ball bearing commercial hinge, so it keeps the same leaf size and bearing type while matching a square mortise. Deltana also offers the CSB45N, a 4-1/2 inch by 4-1/2 inch square hinge supplied in pairs with a non-removable pin, which suits an out-swinging exterior door where the pin needs to stay captive.

The Emtek 94025 is built only at 4-1/2 inch by 4-1/2 inch, so a narrower interior door leaf needs a different part. The Orca Hardware 3514 Series is a 3-1/2 inch by 3-1/2 inch hinge with the same 1/4 inch radius corner, which drops into a standard residential radius mortise; it is a plain bearing hinge rather than ball bearing. Deltana DSB35 is a 3-1/2 inch by 3-1/2 inch square corner residential hinge sold in pairs, and Delaney offers 3-1/2 inch by 3-1/2 inch steel residential interior hinges in pairs with a 5/8 inch radius for jambs cut to the larger radius.

The Emtek 94025 is a standard ball bearing pair. Where the hinges are on the outside of an out-swinging door, specify a security or non-removable pin hinge instead: Deltana CSB45N is a 4-1/2 inch by 4-1/2 inch pair with a non-removable pin, matching the 94025 leaf size. Deltana DE44R5TA is a 4 inch by 4 inch steel security hinge pair with 5/8 inch radius corners, and Hager BB1168 NRP is a full mortise heavy duty ball bearing hinge with a non-removable pin. Delaney also lists 4 inch by 4 inch bulk residential exterior hinges in pairs with a 5/8 inch radius.

They ship as a pair and the mounting screws come in the box. Most doors take three hinges, so a standard 6-foot-8 door needs two packs, with the third hinge left over or a second pair ordered for the next opening. Taller or heavier doors commonly take four.

Ball bearings sit between the knuckles so the leaves ride on the bearing rather than steel on steel. That means quieter swing, less wear, and better behavior under the weight of a solid core or heavy decorative door. Plain bearing hinges, like the Orca Hardware 4 by 4 square corner commercial hinge or the Ives 1010RP residential hinge, have no bearing at all and are the lighter-duty choice.

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. Those are Emtek's standard finish codes, so a property manager standardizing a building can order hinges in the same code as the levers already on the doors.

Steel, with a plated decorative finish. The substrate is steel throughout, and the finish is applied over it, which is why the range covers codes like Polished Brass US3 and Satin Nickel 619. If you need a non-ferrous hinge body, the McKinney T2314 is a non-ferrous 5-knuckle hinge.

The leaves run 0.118 to 0.126 inch thick. That gauge matters when you are mortising: the pocket depth has to match the leaf so the door sits flush in the frame and the gap stays even. If you are swapping in over a shallower existing mortise, plan on taking the pocket a touch deeper rather than forcing the leaf.

Several 4-1/2 inch full mortise hinges are built for a job the Emtek 94025 does not do. Stanley Security's 2060R in 4-1/2 inch by 4-1/2 inch is a spring hinge, so it self-closes rather than swinging free. McKinney SQ3331 is a 4-1/2 inch by 4-1/2 inch two-knuckle decorative hinge with a square barrel, a different look and knuckle count. Stanley CECB1900R54L is a concealed conductor hinge with 4-wire transfer and is handed left, and Command Access ETH-CB70 is an energy transfer hinge for powered locks. BEST CECB179-12C carries 12-wire quick connect. Those electrified and spring types are specified for door power or closing, not as a plain swing hinge.

The Emtek 94025 uses a ball bearing knuckle where the bearing sits between knuckles. If you prefer a smoother barrel line, concealed bearing hinges hide it: Ives 3CB1 is a steel three-knuckle concealed bearing full mortise hinge, and 3CB1HW is the heavy weight version of the same three-knuckle concealed bearing design. Hager 920 is a full mortise concealed bearing hinge built with two knuckles in steel. BEST CB1969R is a concealed bearing heavy weight pivot-reinforced hinge for doors that need reinforcement at the top.

No. The Emtek 94025 is a residential ball bearing hinge pair. Detention openings call for purpose-built hardware such as the BEST BB855 heavy-duty steel double weight concealed ball bearing prison hinge, the Stanley Security double weight prison hinge at 5 inch by 6 inch furnished with no holes and not swaged, or the Hager 990 Steel full surface prison hinge at 3 inch by 4 inch with a welded tip. Those are specified for the abuse levels a correctional or high-security door sees.

The Emtek 94025 is a plated steel ball bearing pair at 4-1/2 inch by 4-1/2 inch with 1/4 inch radius corners, offered in finishes from Flat Black and Polished Nickel to Satin Brass and Bright Chrome for a decorative match to the rest of the trim. McKinney MP79 and MPB79 MacPro hinges are five-knuckle full mortise hinges rated standard duty. If your selection is being driven by finish coordination with knobs and levers, the 94025 finish range is the reason to stay with it; if the spec calls out a five-knuckle standard weight architectural hinge, the MacPro parts answer that call.
