Delaney 4" x 4" Residential Ball Bearing Hinge, 5/8" Radius (Pair)

No. The Delaney 4 inch hinge has 5/8 inch radius (rounded) corners, so it will sit in a square corner mortise with visible gaps at the four corners and the screw pattern may not line up. For square corner preps, Orca Hardware's 4 x 4 square corner commercial hinge is the matching shape, and Deltana's DSB35 covers 3-1/2 inch square. Radius to radius, square to square, is the rule.

Delaney sells these by the pair, so one purchase is two hinges. Most residential doors take three hinges per leaf, so plan on ordering enough pairs to cover that (two pairs per door leaves you a spare, or buy in the 50 pair carton for a whole building). #9 x 1 inch wood screws come supplied with the hinges.

Ball bearing is what you want under weight. The bearings between the knuckles carry the door's load and reduce friction, so a heavier exterior slab swings smoothly and quietly instead of squeaking and sagging over time. Plain bearing hinges (metal on metal) are fine on light interior doors, and if that is the application, Emtek's 91013 residential plain bearing hinge or the Ives 1010RP are the simpler option. For an exterior entry, a storm door, or anything hung with a closer, stay with ball bearing.

It is built and rated for residential use, 0.087 inch gauge steel in a 4 x 4 size. That covers houses, apartments, and light multi-family entry doors. For a commercial opening with a closer and constant traffic, step up to a heavy weight hinge: Don-Jo's HWBB74545 in 4-1/2 x 4-1/2, the Ives 3CB1HW concealed bearing heavy weight, or Hager's BB1168. Those are the ones to spec on a school, hospital, or office door.

If what is on the door now is a 4 x 4 hinge with 5/8 inch radius corners, this is a direct swap into the same mortise, no rerouting. Take one of the old hinges off and measure leaf height and width plus the corner radius before you order. Where the existing hinge is 4-1/2 x 4-1/2 or 3-1/2 x 3-1/2, the mortise is a different size and this one won't fill it.

This Delaney hinge is a standard residential ball bearing butt, not a security hinge. On an outswing exterior door the pins are accessible from outside, which is when you want an NRP or a security stud. Deltana's DE44R5TA is the 4 x 4 with 5/8 inch radius security hinge, so it matches this prep exactly, and Deltana's CSB45N covers 4-1/2 inch square corner with a non-removable pin.

The Delaney 4" x 4" ball bearing hinge is a residential-duty steel hinge with 5/8" radius corners. The nearest 4 x 4 commercial alternatives are the Orca Hardware 4" x 4" x 1/4" Radius Corner Plain Bearing Commercial Hinge, rated medium duty, and the Orca Hardware 4" x 4" Square Corner Plain Bearing Commercial Hinge, also medium duty. Both match the 4 x 4 leaf size, so the mortise depth and height in the frame stay the same. The differences are corner shape and bearing type: the Delaney carries 5/8" radius corners and ball bearings, the Orca 4014 carries 1/4" radius corners and plain bearings, and the Orca 4040 carries square corners and plain bearings. If the existing mortise in the jamb is cut with a 5/8" radius router bit, the 5/8" radius Delaney drops in without recutting; a 1/4" radius or square corner hinge in that pocket leaves a gap at each corner.

No. The Delaney 4" x 4" ball bearing hinge is a plain mechanical hinge with no wire path, so it cannot transfer power from the frame to the door. That opening needs an electric transfer hinge: the Command Access ETH-BB68 is a 5-knuckle heavy duty steel base energy transfer hinge, the Command Access ETH-CB70 is a 3-knuckle standard weight steel base energy transfer hinge rated medium duty, and the BEST CECB179-12C is a steel full mortise concealed bearing electrified hinge with a 12-wire quick connect. If the opening also needs door position monitoring, the Command Access ETM-BB68 adds an integrated door position switch and the ETM-CB70 adds door position sensing on a 3-knuckle steel base. Mechanical hinges like the Delaney fill the remaining hinge locations on the same door.

The Delaney ball bearing hinge is made in 4" x 4" only, so a 4-1/2" opening needs a different part. Among 4-1/2 x 4-1/2 options, the Don-Jo HWBB74545 and Don-Jo HWBB84545 are heavy weight full mortise ball bearing hinges in satin chrome, the Orca Hardware 3535 Series is a 4-1/2" x 4-1/2" square corner ball bearing commercial hinge in medium duty, and the Deltana CSB45N is a 4-1/2" x 4-1/2" square hinge pair with a non-removable pin. Note the corner geometry: the Orca 3535 and the Deltana CSB45N are square corner, so they suit a chisel-cut or square-routed mortise rather than a radius-routed one.

On an out-swing door the hinge pin is on the outside, so the standard Delaney 4" x 4" ball bearing hinge, which is a residential steel hinge with 5/8" radius corners, is usually paired with a pin-security option on the exterior leaves. The Deltana DE44R5TA is a 4" x 4" x 5/8" radius security hinge pair in steel with tamper-resistant construction. It matches the Delaney on leaf size and on the 5/8" radius corner, so it drops into the same routed mortise, and it adds the security feature the exposed-pin condition calls for. The Deltana CSB45N carries a non-removable pin as well, but it is a 4-1/2" x 4-1/2" square hinge, so it needs a different pocket.

The Delaney 4" x 4" ball bearing hinge is rated residential. For commercial openings the comparable set is built around heavier full mortise hinges: the Ives 3CB1HW is a steel heavy weight concealed bearing full mortise hinge with 3 knuckles rated heavy duty, the Hager BB1168 is a full mortise ball bearing heavy duty hinge with a non-removable pin, and the Stanley Security FBB191 is a 5-knuckle full mortise standard weight hinge at 4-1/2" x 4-1/2". Those are the parts specified where the drawing calls for a commercial-grade hinge on a heavy or high-cycle leaf. The Delaney is the right part for a residential-weight door with a 4 x 4 mortise cut to a 5/8" radius.

No, and this is a common mis-order. The Delaney 4" x 4" is a full mortise hinge, meaning both leaves are recessed, one into the door edge and one into the jamb. A half mortise hinge such as the Hager 1129, a half mortise plain bearing commercial hinge in 4-1/2" standard weight steel rated heavy duty, mortises into the frame but surface-mounts to the door. A full surface hinge such as the Hager 990 STEEL, a 3" x 4" full surface prison hinge with a welded tip, screws flat to both the frame and the door face with no mortise at all. Confirm which of the three the existing prep is cut for before ordering, because none of them fit the other's prep.

No handing to specify. This is a full mortise butt hinge with a removable pin, so the same hinge works on a left or right hand door. The only choice at order time is finish: 605 bright brass, 613 satin bronze oil-rubbed, or 619 satin nickel.

Yes, these ship 50 pair per carton, which is the format for a fleet rehang. Everything in the carton is the same 4 x 4 hinge with 5/8 inch radius corners, so once you have confirmed the prep on one door you can standardize the whole building on it. Screws are included with each pair, so there is nothing separate to source. Pick one of the three finishes and stay with it across the property for a consistent look.

#9 x 1 inch wood screws come in the box with each pair. That length is sized for wood jambs and wood door edges. If you are hanging into a hollow metal frame, the supplied wood screws won't hold and you will need machine screws to suit the frame's tapped holes.

The Delaney 4" x 4" ball bearing hinge is a steel hinge in 0.087" gauge, offered in 605 Bright Brass, 613 Satin Bronze Oil-Rubbed, and 619 Satin Nickel plated finishes. Where the base metal itself needs to be non-ferrous, the McKinney T2314 is a non-ferrous hinge in standard weight with 5 knuckles, rated medium duty, and the Don-Jo HWBB85045 is a brass heavy weight full mortise ball bearing hinge at 5" x 4-1/2". Plated steel and solid non-ferrous behave differently once the plating is scratched in a damp opening, so on a pool room, a coastal exterior, or a wash-down area the base metal is the spec to confirm, not the finish name.

In a ball bearing hinge such as the Delaney 4" x 4", ball bearings sit between the knuckles to reduce friction so the door swings more smoothly and quietly. A plain bearing hinge runs knuckle on knuckle with no bearing race. Direct plain bearing counterparts include the Orca Hardware 4" x 4" Square Corner Plain Bearing Commercial Hinge and the Orca Hardware 4" x 4" x 1/4" Radius Corner Plain Bearing Commercial Hinge, both medium duty, and in smaller leaf sizes the Emtek 91013 residential plain bearing hinge pair at 3-1/2" x 3-1/2" and the Schlage Residential S3P1010 3.5" x 3.5" square corner plain bearing mortise hinges. Plain bearing is generally specified for lighter, lower-cycle doors; ball bearing is what carries a heavier slab or a door that swings all day.

The Delaney ball bearing hinge is 4" x 4". For a 3-1/2" leaf, the Emtek 94013 is a heavy duty ball bearing hinge pair at 3-1/2" x 3-1/2" in plated steel. It carries square corners, so it suits a square-cut mortise rather than the 5/8" radius pocket the Delaney is cut for. If the smaller opening does not need a bearing race, the Emtek 92013 heavy duty plain bearing pair and the Deltana DSB35 3-1/2" x 3-1/2" residential square hinge pair cover the same leaf size, and the Deltana DSB3 steps down again to 3" x 3".

No. On the Delaney 4" x 4", the ball bearings sit in visible races between the knuckles, which is why the barrel shows the bearing bands. On a concealed bearing hinge the bearing is hidden inside the knuckle for a smooth barrel look. Examples in that style are the Ives 3CB1, a steel 3-knuckle concealed bearing full mortise hinge rated medium duty, the Hager 920 full mortise concealed plain bearing hinge with 2-knuckle steel construction, and the BEST CB1969R concealed bearing heavy weight pivot-reinforced hinge. If someone is trying to match the look of an existing barrel, this is the distinction to check before ordering, because a concealed bearing hinge and a ball bearing hinge of the same leaf size do not look alike on the door.

A ball bearing hinge like the Delaney 4" x 4" swings freely and holds the door wherever it is left; it has no closing spring. For a self-closing leaf, the Stanley Security 2060R is a full mortise spring hinge with square corners at 4.5" x 4.5" on a ferrous steel base, rated heavy duty. Because it is 4-1/2" square corner, it needs a different mortise from the 4" x 4" 5/8" radius pocket the Delaney fits, so this is a decision to make before the jamb is routed rather than after.

The Delaney 4" x 4" ball bearing hinge is priced and sold by the pair, two hinges per pair, in bulk cartons of 50 pair. A typical interior door takes three hinges, so a three-hinge door consumes one and a half pairs and an even door count works out cleanly across two doors. Some comparable parts are packaged for the three-hinge door directly: the Ives 1010RP steel plain bearing residential hinge comes as a set of 3, and the Schlage Residential S3P1010 3.5" x 3.5" plain bearing mortise hinge comes in a pack of 3. Others match the pair packaging, including the Deltana DSB35 and the Emtek 94013, both sold as pairs. On a multi-door job, count openings times hinges per opening first, then convert to the package the part is sold in.

The Delaney 4" x 4" ball bearing hinge comes in 605 Bright Brass, 613 Satin Bronze Oil-Rubbed, and 619 Satin Nickel, so a set of doors can be standardized on one BHMA finish number across every opening that takes a 4 x 4 hinge. Where the comparable parts publish a finish, they run to the commercial chrome numbers instead: the Don-Jo HWBB74545 and HWBB84545 are satin chrome at 4-1/2" x 4-1/2", as are the Don-Jo HWBB75045 and HWBB85045 at 5" x 4-1/2". If the goal is a decorative finish that reads with the lever and the entry set, the Delaney finish numbers are the ones to match to; if the goal is a back-of-house door where the hinge is not part of the look, satin chrome is the usual commercial answer.

No. The Delaney 4" x 4" full mortise ball bearing hinge is a butt hinge and swings one direction only. A door that must swing both ways needs a double acting pivot such as the BEST DAP-3, a heavy duty double acting pivot for commercial interior doors. That is a pivot set rather than a mortised butt hinge, so the door and frame prep is entirely different, and the decision has to be made before the jamb is cut.

Weight refers to the thickness of the hinge leaf and the size of the bearing, which sets how much door the hinge carries and how many cycles it takes. The Delaney 4" x 4" is a residential hinge in 0.087" gauge steel. In the commercial families the same style is offered at two weights: the McKinney MP79 MacPro full mortise hinge is a 5-knuckle standard weight rated standard duty, and the McKinney MPB79 MacPro is likewise a 5-knuckle standard weight, while the Don-Jo HWBB75045 is a heavy weight full mortise ball bearing hinge at 5" x 4-1/2" and the Ives 3CB1HW is a steel heavy weight concealed bearing full mortise hinge, both rated heavy duty. A heavier slab, a wide leaf, or a door that cycles all day drives the choice up in weight; a normal residential interior or entry door is what the 0.087" gauge Delaney is built for.

They are a different class of part, not an upgrade path. The Delaney 4" x 4" is a residential full mortise ball bearing hinge for a standard wood door and jamb. Detention hinges such as the BEST BB855 heavy-duty steel double weight concealed ball bearing prison hinge and the Stanley Security BB855 double weight prison hinge at 5" by 6", furnished with no holes and not swaged, are built for secure detention openings and are supplied undrilled for welded or field-prepped installation. The Stanley part at 5" by 6" also carries a leaf size no residential jamb is mortised for. If the requirement is simply a stronger hinge on a normal commercial door, the heavy weight full mortise ball bearing hinges are the relevant family, not the detention line.

The Delaney 4" x 4" ball bearing hinge has a conventional barrel with 5/8" radius corner leaves and is finished in 605 Bright Brass, 613 Satin Bronze Oil-Rubbed, or 619 Satin Nickel, so the decorative element is the plating rather than the barrel shape. Where the barrel itself is meant to be a design feature, the McKinney SQ3331 is a square barrel 2-knuckle decorative hinge at 4-1/2" by 4-1/2" in standard duty, and the Emtek 96213 is a heavy duty hinge pair at 3-1/2" x 3-1/2" with square corners. Both differ from the Delaney in leaf size, so the mortise has to suit before the look is chosen.
