Delaney 4" x 4" Commercial Ball Bearing Hinge Square Corner

The Delaney commercial ball bearing hinge measures 4 x 4 inches with square corners, so it replaces an existing 4 x 4 square corner mortise without recutting the pocket. If your current hinges have radius corners, or measure 3-1/2 x 3-1/2 or 4-1/2 x 4-1/2, the mortise will not match and you would need a hinge cut to that size and corner style.

Pricing is per pair, so one order gets you two hinges. The factory box holds 1.5 pair (3 pieces), which is the usual count for a standard commercial door needing three hinges, and a carton holds 15 pair at 20 lbs.

Order the non-removable pin option any time the hinge barrel is on the outside of an out-swinging door, which covers most exterior and stairwell openings. The NRP set screw sits behind the door when it is closed and stops the pin being driven out. For interior in-swing doors, the standard non-NRP version is fine. Both choices are offered in 613 Satin Bronze Oil-Rubbed and US26D Dull Chrome.

No. The Delaney 4 inch x 4 inch commercial ball bearing hinge is a standard 5 knuckle full mortise hinge with no wiring. For electrified openings, the Command Access ETH-BB68 is a 5 knuckle heavy duty steel energy transfer hinge, 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.

The Delaney 4 inch x 4 inch commercial ball bearing hinge is a 5 knuckle full mortise hinge with square corners in 0.13 inch steel. The nearest same-size square corner commercial alternative is the Orca Hardware 4 inch x 4 inch square corner commercial hinge, which is a plain bearing medium duty hinge rather than ball bearing. If the ball bearing action matters for a door with a closer or heavy traffic, stay with the Delaney; if the opening is a low-cycle interior door, the plain bearing Orca matches the mortise footprint.

The Delaney commercial ball bearing hinge is a 4 inch x 4 inch hinge, so it will not fill a 4-1/2 inch mortise. For that prep, the Orca Hardware 4-1/2 inch x 4-1/2 inch square corner ball bearing commercial hinge keeps the same ball bearing, square corner configuration at the larger size. The Stanley Security FBB191 4.5 x 4.5 is another 4-1/2 inch square option, a 5 knuckle full mortise standard weight hinge.

The Delaney 4 inch x 4 inch commercial ball bearing hinge is a full mortise hinge, so both leaves mortise into the door and the frame. Where the frame cannot be mortised, the Hager 1129 is a half mortise commercial hinge, 4-1/2 inch standard weight steel, and the Hager 990 STEEL is a full surface hinge at 3 inch x 4 inch with a welded tip.

Both wood and metal screws are packed with the hinges, so you are covered for a wood door or a hollow metal frame without buying fasteners separately.

Ball bearings carry the load on doors that get cycled hard or that have a closer pulling on them, which is why this 5 knuckle 0.13 inch gauge hinge is spec'd commercial. A plain bearing hinge is the cheaper choice for low-traffic interior openings, and if that fits your job, the Orca Hardware 4040 Series is a 4 x 4 square corner plain bearing commercial hinge in the same size.

The Delaney commercial ball bearing hinge is 4 x 4 only. For a 4-1/2 inch square corner ball bearing hinge, the Orca Hardware 3535 Series is that size and corner style. Deltana's CSB45N is a 4-1/2 x 4-1/2 square hinge supplied as a pair with a non-removable pin if NRP is what you need at that size.

No handing to pick. A full mortise 5 knuckle butt hinge with a removable or NRP pin works on either hand, so you only choose finish and whether you want the non-removable pin. Handing only becomes an ordering question on hinges like the Stanley CECB1900R54L, which is listed left-handed because of the wire routing.

No, they are larger. At 4 x 4 inches these are sized for commercial-weight doors. Standard residential interior doors typically use 3-1/2 x 3-1/2, and for that size the Schlage Residential S3P1010 square corner plain bearing hinge comes in packs of three, or the Deltana DSB35 as a pair.

Both are square corner ball bearing hinges sold by the pair, but the sizes differ. The Emtek 94013 is 3-1/2 inch x 3-1/2 inch in plated steel, while the Delaney is 4 inch x 4 inch in 0.13 inch steel. Use the Emtek where the door is prepped for 3-1/2 inch hinges and the Delaney where the prep is 4 inch.

The Delaney 4 inch x 4 inch ball bearing hinge is a 5 knuckle full mortise commercial hinge in 0.13 inch steel. For heavier or higher-frequency openings, the Ives 3CB1HW is a heavy weight concealed bearing full mortise steel hinge with 3 knuckles, and the BEST CB1969R is a concealed bearing heavy weight pivot-reinforced hinge. Both move the bearing inside the barrel rather than exposing it between knuckles.

Steel construction at 0.13 inch gauge, offered in two finishes: 613 Satin Bronze Oil-Rubbed and US26D Dull Chrome. Those two cover the common commercial pairings, US26D with brushed chrome levers and 613 with oil-rubbed bronze trim, so you can match the rest of the openings without mixing brands.

The Delaney 4 inch x 4 inch hinge is a 5 knuckle ball bearing design with the bearings visible between the knuckles. For a concealed bearing look, the Ives 3CB1 is a 3 knuckle concealed bearing full mortise steel hinge rated medium duty, and the Hager 920 is a 2 knuckle full mortise concealed plain bearing hinge in steel.

Both are 5 knuckle commercial hinges. The McKinney MPB79 MacPro is a 5 knuckle standard weight hinge, as is the MP79 MacPro full mortise version. The Delaney is a 5 knuckle full mortise ball bearing hinge in a 4 inch x 4 inch size with square corners and 0.13 inch steel, sold by the pair with wood and metal screws included.

For a light interior door with smaller prep, the Deltana DSB3 is a 3 inch x 3 inch square hinge pair and the DSB35 is a 3-1/2 inch x 3-1/2 inch residential square hinge pair. Both are smaller than the Delaney 4 inch x 4 inch commercial ball bearing hinge, which is the commercial-duty choice at the larger prep.
