Delaney 4 1/2" x 4 1/2" Commercial Ball Bearing Hinge Square Corner

NRP is a non-removable pin, and the Delaney 4 1/2" x 4 1/2" ball bearing hinge is ordered either way, NRP or standard pin. On an outswing door the hinge barrel sits on the exposed side, so anyone with a punch can drive the pin and lift the door off. The NRP version has a set screw in the barrel that engages the pin once the door is closed and stops that. Inswing doors put the barrel on the secure side, so the standard pin is fine there. Both pin choices are offered in all four finishes.

Ball bearing is what you want on any door that cycles hard or carries a closer. The Delaney 4 1/2" hinge is a 5 knuckle ball bearing full mortise unit, with bearings between the knuckles that carry the door weight and cut the friction a closer has to fight. Plain bearing hinges have no bearings and are meant for lighter interior and residential use, like the Orca Hardware 4" x 4" square corner plain bearing hinge or the Emtek 92013 heavy duty plain bearing hinge. On an entrance, a stairwell, or a corridor door with a closer, go ball bearing.

If what is coming off is a 4-1/2 by 4-1/2 square corner full mortise hinge, the Delaney is a like-for-like swap into the existing mortise and screw pattern. Check the corners first: a 4-1/2 hinge with rounded corners means a radiused mortise and this square corner leaf will leave gaps at the corners. Also confirm the leaf size, not the door size, since 5" x 4-1/2" hinges show up on heavier openings and take a taller mortise.

It cannot. The Delaney 4-1/2" x 4-1/2" ball bearing hinge is a mechanical 5 knuckle full mortise hinge with no wire path through the barrel. For power transfer to an electric strike, electrified lock, or exit device, use an energy transfer hinge: the Command Access ETH-BB68 is a 5 knuckle heavy duty steel base energy transfer hinge in the ETH 5 Series, and the Command Access ETH-CB70 is a 3 knuckle standard weight steel base version at medium duty. If you also need door position monitoring, the Command Access ETM-BB68 adds an integrated door position switch. A common build is to hang the door on standard ball bearing hinges like the Delaney and use one transfer hinge in the middle position for the wire run.

The Orca Hardware 3535 Series is the nearest match: a 4-1/2" x 4-1/2" square corner ball bearing commercial hinge, same size, same corner style, same bearing type as the Delaney 4-1/2" x 4-1/2" commercial ball bearing hinge with square corners. Both drop into a standard 4-1/2 inch square corner mortise already cut into the frame and door, so neither requires reworking the prep. The Delaney is stainless steel at 0.134" gauge with 5 knuckles and ships packed with both wood and metal screws, priced per pair. If you are matching an existing opening prep and just need another ball bearing hinge in the same footprint, the Orca 3535 is the substitution that does not change the mortise.

Step up to the Don-Jo HWBB84545, a heavy weight full mortise ball bearing hinge in 4-1/2" x 4-1/2" with a satin chrome finish. It keeps the same 4-1/2 inch square footprint as the Delaney 4-1/2" x 4-1/2" commercial ball bearing hinge, so the frame and door prep carries over, but it is built at a heavy duty level rather than the Delaney's 0.134" gauge steel/stainless standard commercial build. The Don-Jo HWBB74545 is the other heavy weight 4-1/2" x 4-1/2" ball bearing option in satin chrome. Both are the move for high-cycle openings - main entries, stairwell doors, tenant corridors - where you want more material in the leaf without changing the mortise size.

They are not the same part. The Delaney 4-1/2" x 4-1/2" square corner hinge is a 5 knuckle ball bearing full mortise hinge - the bearings sit between the knuckles and carry the door weight through the swing. A plain bearing hinge such as the Orca Hardware 4040 Series, a 4" x 4" square corner plain bearing commercial hinge, has no bearings in the knuckles and runs metal on metal. The Orca 4040 is also 4" x 4" rather than 4-1/2" x 4-1/2", so the mortise depth and height differ from the Delaney and the prep will not line up. If the door already carries 4-1/2 inch square corner ball bearing hinges, a 4" plain bearing hinge is not the replacement.

Both address the same security concern on an out-swinging exterior door, where a removable pin can be driven out from the unsecured side. The Delaney 4-1/2" x 4-1/2" square corner ball bearing hinge is ordered with the non-removable pin option set to Yes, in 630 satin stainless steel, 613 satin bronze oil-rubbed, US26D dull chrome, or 622 matte black, and it is a 5 knuckle hinge at 0.134" gauge. The Hager BB1168 is a non-removable pin full mortise ball bearing hinge built at a heavy duty level. For a locksmith or integrator specifying an out-swing exterior leaf, the Delaney NRP covers it in four commercial finishes; the Hager BB1168 NRP is the heavy duty route when the opening calls for more leaf material.

No. The Delaney 4-1/2" x 4-1/2" commercial hinge has square corners, and a square corner leaf will not seat in a mortise routed with a rounded corner radius. For a radius prep, the Orca Hardware 4014 Series is a 4" x 4" x 1/4" radius corner plain bearing commercial hinge, and the Orca 3514 Series is a 3.5" x 3.5" x 1/4" radius corner plain bearing commercial hinge. Check the existing hinge leaf against the frame cutout before ordering: square corner and radius corner are not interchangeable in either direction without rerouting the mortise.

The Delaney 4-1/2" x 4-1/2" commercial ball bearing hinge is a standard swinging hinge with no spring in the barrel - it holds the door wherever you leave it. For a leaf that must return itself, the Stanley Security 2060R is a spring hinge, full mortise, square corner, 4.5" x 4.5" on a ferrous steel base at a heavy duty level. It matches the Delaney's 4-1/2 inch square corner footprint, so the same mortise applies, but the spring does the closing. Common call on utility rooms and back-of-house doors where a surface closer is not wanted.

No. The Delaney 4-1/2" x 4-1/2" ball bearing hinge is a full mortise hinge, meaning both leaves mortise in - one into the door edge, one into the frame rabbet. If the frame cannot be mortised, the Hager 1129 is a half mortise plain bearing commercial hinge in 4-1/2" standard weight steel at a heavy duty level, which mortises into the door and surface-applies to the frame. For a frame that takes nothing at all, the Hager 990 STEEL is a full surface prison hinge, 3" x 4", with a welded tip. Confirm which mounting the existing opening actually has before ordering, since full mortise, half mortise, and full surface are not interchangeable.

No extra fasteners needed. The Delaney 4 1/2" ball bearing hinge ships packed with both wood and metal screws, so the same box covers a wood door in a wood frame or a hollow metal door in a steel frame without a separate hardware order.

Leaf thickness is 0.134" in steel or stainless steel, and the substrate on record is stainless steel. That 0.134 gauge is the standard heavy weight leaf thickness for a 4-1/2 inch commercial hinge. Stainless holds up better than plated steel where there is moisture or salt air, which is what makes it a reasonable call for exterior entrances, pool and locker areas, and kitchens.

Four finishes: 630 satin stainless steel, 613 satin bronze oil-rubbed, US26D dull chrome, and 622 matte black. If your building is standardized on 630 stainless levers and exit devices, the 630 hinge is the match. US26D dull chrome is the satin chrome tone commonly specified alongside 626 lever hardware, so it is the one to pick when your existing trim is 626 rather than 630. All four finishes are available with or without the non-removable pin.

Closest peers in the same size and bearing type: the Don-Jo HWBB74545 heavy weight full mortise ball bearing hinge at 4-1/2" x 4-1/2" in satin chrome, the Don-Jo HWBB84545 in the same size and finish, and the Orca Hardware 3535 Series 4-1/2" x 4-1/2" square corner ball bearing hinge, which is rated medium duty. If the opening needs a non-removable pin from a different brand, the Hager BB1168 NRP is a heavy duty full mortise ball bearing hinge, and the Deltana CSB45N is a 4-1/2" x 4-1/2" square hinge sold as an NRP pair.

Physically yes, but it is oversized for most of them. The Delaney is a commercial hinge at 4 1/2" x 4 1/2", while interior residential doors are usually prepped for 3-1/2 inch hinges. Swapping means re-routing the door and jamb. For unit interior doors, a 3-1/2 inch square corner hinge such as the Emtek 94013 heavy duty ball bearing pair or the Schlage Residential S3P1010 plain bearing set drops into the existing prep. Save the 4-1/2 commercial hinge for unit entry doors, corridor doors, and stairwells.

They are different constructions. The Delaney 4-1/2" x 4-1/2" hinge is a 5 knuckle ball bearing full mortise hinge, so the bearing races are visible between the knuckles on the barrel. The Ives 3CB1 is a 3 knuckle concealed bearing full mortise hinge at a medium duty level, where the bearings are hidden inside the knuckle for a smooth barrel line, and the Ives 3CB1HW is the heavy weight 3 knuckle concealed bearing version. The Hager 920 is a 2 knuckle full mortise concealed bearing hinge at medium duty. All are full mortise hinges, but if a facility standard calls for a 5 knuckle barrel to match the rest of the doors, a 3 knuckle concealed bearing hinge will read differently in the opening.

The Delaney commercial ball bearing hinge is built at 4 1/2" x 4 1/2". For a 5 inch leaf height, the Don-Jo HWBB75045 is a heavy weight full mortise ball bearing hinge at 5" x 4-1/2" in steel with a satin chrome finish, and the Don-Jo HWBB85045 is a 5" x 4-1/2" heavy weight full mortise ball bearing hinge in brass with a satin chrome finish. Both are heavy duty. Wider and taller leaves are the usual call on thick or oversized doors where a 4-1/2 inch hinge does not put enough leaf into the door edge - measure the existing mortise height before ordering, since a 5 inch hinge needs the frame prep extended.

They share a size but not a build. The McKinney SQ3331 is a square barrel 2 knuckle decorative hinge at 4-1/2" by 4-1/2", rated standard duty. The Delaney 4-1/2" x 4-1/2" commercial hinge is a 5 knuckle ball bearing full mortise hinge at 0.134" gauge stainless steel, built for commercial use. The SQ3331's square barrel and 2 knuckle profile is a design choice for openings where the hinge is meant to be seen; the Delaney's 5 knuckle barrel with ball bearings is the standard commercial profile. If you are matching the barrel appearance of existing 5 knuckle hinges down a corridor, the SQ3331 will not blend.

The Stanley Security FBB191 in 4.5" x 4.5" is a 5 knuckle full mortise standard weight hinge at a heavy duty level, matching the Delaney 4-1/2" x 4-1/2" hinge on knuckle count, size, and full mortise mounting. The McKinney MP79 MacPro is another 5 knuckle full mortise standard weight hinge, rated standard duty, and the McKinney MPB79 MacPro is a 5 knuckle standard weight hinge as well. Any of these keeps the 5 knuckle barrel look consistent with the Delaney if you are hanging some doors on one part and some on another across the same building.

That is a different class of hinge. The Delaney 4-1/2" x 4-1/2" square corner ball bearing hinge is a commercial full mortise hinge, and the non-removable pin option covers the ordinary out-swing security concern. For detention work, the BEST BB855 is a heavy-duty steel double weight concealed ball bearing prison hinge in the Detention Hardware series, and the Stanley Security BB855 is a double weight prison hinge at 5" by 6", furnished with no holes and not swaged, at a heavy duty level. Those are specified where the leaf itself is an attack surface; the Delaney NRP is the answer for a standard commercial exterior door, not a secure housing unit.

The Delaney 4-1/2" x 4-1/2" commercial ball bearing hinge is offered in stainless steel, which is the usual choice for damp interior and protected exterior openings, in 630 satin stainless steel among its finishes. The McKinney T2314 is a non ferrous hinge, standard weight, 5 knuckle, at a medium duty level - same 5 knuckle barrel profile as the Delaney, with a non ferrous base material rather than a steel one. Non ferrous is the specification you see written on pool decks, kitchens, and salt-air exterior openings where a plated steel base will not hold up.
