Orca Hardware 4" x 4" x 5/8" Radius Corner Ball Bearing Residential Hinge

The Orca 4058BB is a 4 x 4 inch full mortise hinge with 5/8 inch radius corners, which is the corner cut most residential prehung doors and steel frames are routed for. If the existing mortise in your door and jamb is 4 x 4 with rounded corners, this drops straight in with no chiseling. If your pockets are square cornered, you need a square corner hinge instead, not this one.

No. The 4058BB is built for residential application in zinc alloy. Use it on house doors, apartment interiors, and light unit turnover work. For a lobby, corridor, or any door on a closer or heavy public traffic, go to a commercial steel hinge such as the Don-Jo HWBB84545 heavy weight full mortise ball bearing hinge or the Ives 3CB1HW concealed bearing hinge.

The Orca 4058BB is 4 x 4 only. For a 3-1/2 inch mortise with the same 5/8 inch radius corner, the Delaney RH35 bulk steel residential interior hinges are 3-1/2 x 3-1/2 with 5/8 inch radius. Do not try to fill a 3-1/2 inch pocket with a 4 inch hinge; the leaf will overhang the routed mortise on both the door and the jamb.

No. The Orca 4058BB is a mechanical residential ball bearing hinge with no wire path through it. For power transfer, Command Access ETH-BB68 is an energy transfer hinge with a 5 knuckle heavy duty steel base, and ETH-CB70 is the 3 knuckle standard weight steel base version at a medium duty rating. If the opening also needs door position status, Command Access ETM-BB68 is an energy transfer monitor hinge with an integrated door position switch at heavy duty, and ETM-CB70 is the 3 knuckle steel base monitor version at medium duty. BEST CECB179-12C is a steel full mortise concealed bearing electrified hinge with a 12 wire quick connect, medium duty, when the lock needs more conductors than a standard transfer carries.

The Orca 4058BB is a standard residential ball bearing hinge with 5/8 inch radius corners, not a security hinge. For an out-swing opening where the pin is exposed, the Deltana DE44R5TA is a 4 inch by 4 inch hinge with 5/8 inch radius corners built as a security hinge in steel with a TT pin option, sold as a pair, and it shares the same 4 inch radius mortise the Orca takes. If the frame is prepped for square corners at 4-1/2 inch, the Deltana CSB45N is a 4-1/2 inch by 4-1/2 inch square hinge with a non-removable pin, sold as a pair. On a commercial opening, Hager BB1168 is a non-removable pin full mortise ball bearing hinge at a heavy duty rating.

The Delaney RH45xx exterior residential hinge is the nearest match on size and corner prep: it is a 4 inch by 4 inch residential hinge with 5/8 inch radius corners, sold as a pair, so it drops into the same routed mortise as the Orca 4058BB without recutting the door or frame. The Orca 4058BB is a ball bearing hinge in a 4 inch by 4 inch size with 5/8 inch radius corners for residential use. Delaney also builds the RH40xx in 4 inch by 4 inch with a 5/8 inch radius by square combination for Castlegate doors, which suits an opening where one leaf meets a square-cornered frame prep.

The Orca 4058BB is a 4 inch by 4 inch hinge and will not fit a 3-1/2 inch mortise. For a 3-1/2 inch interior residential opening with the same 5/8 inch radius corner prep, Delaney RH35xx is a 3-1/2 inch by 3-1/2 inch bulk steel residential interior hinge with 5/8 inch radius corners, sold as a pair. If those doors are cut square instead, Deltana DSB35 is a 3-1/2 inch by 3-1/2 inch square residential hinge sold as a pair, and DSB3 is the 3 inch by 3 inch square version for smaller closet and utility doors.

The Orca 4058BB is built for residential applications. For a heavy commercial leaf, the Don-Jo HWBB74545 is a heavy weight full mortise ball bearing hinge in 4-1/2 inch by 4-1/2 inch, satin chrome, heavy duty; the HWBB84545 is the same 4-1/2 inch by 4-1/2 inch size in the 8 prefix, also heavy duty. Where the door is wider and needs a taller leaf, Don-Jo HWBB75045 is a 5 inch by 4-1/2 inch heavy weight steel ball bearing hinge and HWBB85045 is the 5 inch by 4-1/2 inch brass version, both heavy duty in satin chrome. All four are a larger mortise than the 4 inch by 4 inch cut the Orca takes, so the frame and door have to be prepped for them.

Ball bearings sit between the knuckles and carry the door's weight on a rolling surface, so the door swings quieter and the hinge wears slower under repeated use. The 4058BB is ball bearing. A plain bearing hinge is metal riding on metal and is fine on a light interior door that does not get much traffic. If you are hanging a heavier solid core or exterior slab, or the door is used constantly, ball bearing is the one to pick. Plain bearing residential options include the Ives 1010RP and the Schlage Residential S3P1010.

Five finishes: oil-rubbed bronze, satin nickel, painted black, polished chrome, and bright brass. That covers the common residential trim looks, so a property manager standardizing a building can pick one and repeat it across units without mixing hinge appearance from door to door.

No. The 4058BB is listed as not ADA compliant. If the opening has to satisfy an accessibility scope of work, this hinge is not the part to specify for it.

The 4058BB is a single hinge, ordered by the piece, unlike several residential hinges that ship two to a pack (the Delaney RH40 and Deltana DSB35 are sold as pairs). Most residential doors take three hinges per leaf, so count three per opening when you build the order.

No handing to specify. A full mortise butt hinge like the 4058BB is symmetrical, so the same part works on a left hand or right hand door. You only pick the finish. Handing becomes a question on electrified and concealed-conductor hinges, where the wire exit is handed, as on the Stanley CECB1900R54L which is a left-handed hinge.

The 4058BB is zinc alloy and rated residential. It will serve on a typical house entry, but for a heavier exterior slab or a coastal or high-cycle exterior opening a steel-based hinge holds up better. The Delaney RH45 bulk residential exterior hinges are 4 x 4 with the same 5/8 inch radius corner, and the Don-Jo HWBB75045 is a 5 x 4-1/2 heavy weight steel ball bearing hinge for the heaviest slabs.

It will not. The Orca 4058BB is a ball bearing hinge with no spring in the barrel, so the door stays where you leave it. For self-closing, the Stanley Security 2060R is a full mortise spring hinge with square corners, 4.5 inch by 4.5 inch, on a ferrous steel base at a heavy duty rating. On a commercial interior door that has to swing both directions and return to center, the BEST DAP-3 is a heavy duty double acting pivot rather than a hinge, which changes the door and frame prep entirely.

The Orca 4058BB is a full mortise hinge, meaning both leaves mortise into the door edge and the frame. Several hinges that share the ball bearing or full mortise wording take a completely different prep. Hager 1129 is a half mortise plain bearing commercial hinge in 4-1/2 inch standard weight steel, heavy duty, which mortises to the door and surface-applies to the frame. Hager 990 STEEL is a full surface prison hinge, 3 inch by 4 inch with a welded tip, heavy duty, and mounts on the face of both door and frame. BEST BB855 is a heavy duty steel double weight concealed ball bearing prison hinge in the detention line, and Stanley Security BB855 is a double weight prison hinge, 5 inch by 6 inch, furnished with no holes and not swaged. None of those go into a 4 inch by 4 inch residential mortise.

Where corrosion is the concern, McKinney T2314 is a non ferrous hinge in standard weight with 5 knuckles at a medium duty rating, which avoids a ferrous base entirely. Don-Jo HWBB85045 is a brass heavy weight full mortise ball bearing hinge in 5 inch by 4-1/2 inch with a satin chrome finish for a heavier exterior leaf. The Orca 4058BB is zinc alloy and is offered in oil-rubbed bronze, satin nickel, painted black, polished chrome, and bright brass, so on a sheltered exterior residential opening it may still be the right call.

The Orca 4058BB is specified for residential use, so on a light commercial door the standard weight commercial lines are the closer fit. McKinney MP79 MacPro is a 5 knuckle full mortise hinge in standard weight at a standard duty rating, and the MPB79 MacPro is the 5 knuckle standard weight version in the same MacPro family. Stanley Security FBB191 is a 5 knuckle full mortise standard weight hinge in 4.5 inch by 4.5 inch at a heavy duty rating. All three sit in a larger or different frame prep than the 4 inch by 4 inch radius mortise the Orca takes, so confirm the cut before ordering.

RES4058BB, from Orca Hardware's 4058BB Series. The number covers the 4 x 4 inch full mortise ball bearing hinge with 5/8 inch radius corners; the finish is the only thing that changes across the series.

The Orca 4058BB comes in oil-rubbed bronze, satin nickel, painted black, polished chrome, and bright brass, which covers most residential trim packages off one part number. If the barrel itself is meant to be a design element, the McKinney SQ3331 is a square barrel 2 knuckle decorative hinge in 4-1/2 inch by 4-1/2 inch at a standard duty rating, though that is a larger mortise and a square barrel profile rather than the round barrel the Orca uses. Emtek 96213 is a heavy duty hinge in 3-1/2 inch by 3-1/2 inch with square corners for a smaller decorative opening.

Most full mortise butt hinges of this type are non-handed and work on either swing, which keeps stocking simple across a building. Handing shows up once electrical conductors are involved: the Stanley Security CECB1900R54L is a three knuckle concealed bearing concealed conductor architectural hinge, steel full mortise, standard weight, 4-1/2 inch by 4-1/2 inch, square corner, left-handed, 4-wire, so it has to be ordered to the door's hand. The Orca 4058BB is a mechanical 4 inch by 4 inch ball bearing hinge with 5/8 inch radius corners and carries no conductors.
