Delaney 4 1/2" x 4 1/2" Heavy Duty Ball Bearing Hinge NRP, US26D Dull Chrome Finish

Yes. NRP stands for non-removable pin, so once the door is closed the hinge pin cannot be driven out from the outside. That is exactly what you want on an outswing door where the barrels are exposed, and it is the reason this hinge gets specified on exterior and tenant entry openings rather than a plain hinge with a loose pin.

The Hager BB1168 is the nearest match in intent: it is a non-removable pin full mortise ball bearing hinge rated heavy duty, the same combination the Delaney 4 1/2 inch x 4 1/2 inch heavy duty ball bearing hinge offers with NRP. The Deltana CSB45N is another NRP option at the same 4-1/2 inch by 4-1/2 inch square size, sold as a pair. The Delaney is a 5 knuckle, heavy weight steel hinge in 0.18 inch gauge with square corners, also priced per pair.

A plain ball bearing hinge like the Delaney 4 1/2 inch x 4 1/2 inch heavy duty ball bearing hinge has no wire path. For power transfer, the Command Access ETH-BB68 is an energy transfer hinge with a 5 knuckle heavy duty steel base, the closest analogue in knuckle count and duty. The BEST CECB179-12C is a steel full mortise concealed bearing electrified hinge with a 12-wire quick connect, and the Stanley CECB1900R54L is a 4-1/2 inch by 4-1/2 inch square corner concealed conductor hinge in a 4-wire left-handed configuration. If you also need door position monitoring, the Command Access ETM-BB68 adds an integrated door position switch.

The Orca Hardware 3535 Series is a 4-1/2 inch by 4-1/2 inch square corner ball bearing commercial hinge rated medium duty, so it keeps the same size and corner style while stepping down from the heavy weight construction of the Delaney 4 1/2 inch x 4 1/2 inch hinge, which is a heavy weight 0.18 inch gauge steel hinge. The Stanley FBB191 in 4.5 inch by 4.5 inch is a 5-knuckle full mortise standard weight hinge, another same-size option with lighter leaf weight.

The Delaney ball bearing hinge is built as a heavy weight, five knuckle full mortise hinge in 0.18 inch steel, and it is designated for commercial use. That gauge plus ball bearings in the knuckles is what carries a solid core wood or hollow metal door under a closer and repeated daily traffic. For a light residential interior door you do not need this much hinge.

Use ball bearing. Plain bearing hinges wear and start to sag once a closer is pulling the door shut thousands of times, which is why the Delaney hinge uses ball bearings between the knuckles. Plain bearing options like the Emtek 92013 heavy duty plain bearing hinge or the Orca Hardware 4" x 4" square corner plain bearing hinge are fine on doors without a closer, but a closered opening should get bearings.

No. Each box is packed with both wood and metal screws, so you are covered whether you are hanging into a solid core wood door or a hollow metal door and frame. Nothing else is required to hang the door if the mortise pockets are already cut.

US26D dull chrome is the standard satin chrome commercial finish, the same family as the satin chrome lever sets and closers typically specified on institutional and multi-family openings. If your existing hinges are marked US26D or the equivalent satin chrome code, this hinge matches. It will not match satin stainless or oil rubbed bronze openings.

No handing to call out. A full mortise butt hinge like this 4 1/2" x 4 1/2" Delaney is symmetrical and works on a left or right hand door. Handing only becomes an order decision on hinges with wiring or switches, such as the Stanley Security concealed conductor hinge that is sold left-handed with a 4-wire harness.

The Delaney 4 1/2 inch x 4 1/2 inch hinge is a 5 knuckle ball bearing full mortise hinge, so the bearings sit visibly between the knuckles. The Ives 3CB1HW is a heavy weight steel concealed bearing full mortise hinge with 3 knuckles, which hides the bearing inside the barrel and gives a different barrel appearance. Ives also lists the 3CB1 as a 3-knuckle concealed bearing full mortise hinge in medium duty, and the Hager 920 is a 2 knuckle full mortise concealed plain bearing hinge in medium duty.

The Stanley 2060R in 4.5 inch by 4.5 inch is a full mortise spring hinge with square corners on a ferrous steel base, rated heavy duty, so it matches the 4 1/2 inch by 4 1/2 inch square corner footprint of the Delaney heavy duty ball bearing hinge while adding closing spring action. The Delaney hinge is a plain pivoting ball bearing hinge with no spring.

The Delaney 4 1/2 inch x 4 1/2 inch hinge is a heavy weight commercial ball bearing hinge in 0.18 inch steel with a non-removable pin. For detention work the set includes purpose-built options: the BEST BB855 is a heavy-duty steel double weight concealed ball bearing prison hinge in the Detention Hardware series, the Stanley BB855 is a double weight prison hinge furnished with no holes and not swaged in 5 inch by 6 inch, and the Hager 990 STEEL is a full surface prison hinge 3 inch by 4 inch with a welded tip in heavy duty.

No. The Hager 1129 is a half mortise plain bearing commercial hinge at 4-1/2 inch standard weight, so one leaf mortises into the door and the other surface-applies to the frame. The Delaney 4 1/2 inch x 4 1/2 inch heavy duty ball bearing hinge is a full mortise hinge, mortised into both door and frame, and uses ball bearings rather than plain bearings. For a full mortise swap at the same size, look at the Deltana CSB45N or Stanley FBB191 4.5 inch by 4.5 inch.

They do not self close. This is a standard ball bearing butt hinge, so a closer or spring hinge is needed if the door has to return on its own. A spring option in the same size is the Stanley Security 2060R full mortise spring hinge, 4.5" x 4.5" square corner in heavy duty.

The Delaney heavy duty ball bearing hinge is 4 1/2 inch by 4 1/2 inch with square corners. For smaller square corner leaves, Deltana lists the DSB3 at 3 inch by 3 inch and the DSB35 at 3-1/2 inch by 3-1/2 inch, Emtek lists the 91013 residential plain bearing and 92013 heavy duty plain bearing hinges at 3-1/2 inch by 3-1/2 inch square corners, and Schlage Residential lists the S3P1010 at 3.5 inch by 3.5 inch square corner plain bearing mortise hinges in a pack of three.

Both are 4-1/2 inch by 4-1/2 inch, but they are built for different jobs. The McKinney SQ3331 is a square barrel 2-knuckle decorative hinge rated standard duty. The Delaney 4 1/2 inch x 4 1/2 inch hinge is a 5 knuckle heavy weight ball bearing full mortise hinge in 0.18 inch steel with a non-removable pin, specified for commercial use. Choose the McKinney where barrel appearance drives the decision and the Delaney where traffic and security pin do.
