Deltana S45BB 4-1/2" x 4-1/2" Square Hinge, Heavy-Duty, Ball Bearings, Steel (Pair)

The S45BB is a 4-1/2 x 4-1/2 inch full mortise hinge with square corners, so it drops into a standard square-cut 4-1/2 inch mortise with no corner radius. If the pockets in your door and jamb are cut with rounded corners (the common 1/4 or 5/8 inch radius), this leaf will not seat without recutting the corners. Leaf thickness is .134, and it ships as a pair.

Square corner leaves won't seat in a radiused pocket. For a 1/4 inch radius, Orca Hardware's 4014 Series is a 4 x 4 inch plain bearing commercial hinge with 1/4 inch radius corners, and the 3514 Series is the same in 3-1/2 x 3-1/2. For a 5/8 inch radius, Delaney's 4 x 4 inch exterior residential hinges (RH45) and 3-1/2 inch interior hinges (RH35) both use a 5/8 inch radius and ship as pairs. Measure the corner of your existing leaf before ordering.

No. The S45BB is classified residential, and it's a steel hinge Deltana positions for indoor applications. It's the right call for apartment interiors, closets, and unit doors in a rental portfolio. For a commercial opening or a heavily used entrance, move to a commercial hinge such as the Orca 3535 Series, a 4-1/2 x 4-1/2 square corner ball bearing commercial hinge, or the Don-Jo HWBB84545 heavy weight full mortise ball bearing hinge in the same 4-1/2 x 4-1/2 size.

No, a 4-1/2 inch leaf won't drop into a 4 inch pocket, and going up a size means recutting both the door and the jamb mortise. Match what's there. For a 4 x 4 square corner replacement, the Orca 4040 Series is a 4 x 4 square corner commercial hinge, and Delaney's CH401X is a 4 x 4 commercial ball bearing hinge with square corners if you want to keep the ball bearing.

The Hager BB1168 NRP is the hinge for that opening: a non-removable pin full mortise ball bearing hinge, heavy duty. The Deltana S45BB is a full mortise ball bearing hinge that is not supplied with a non-removable pin, which is fine on an inswing or interior leaf where the barrel is on the secure side. Where the barrel sits outside, the BB1168 NRP keeps the pin from being driven out and the door lifted off.

The Orca Hardware 3535 Series is the nearest match in the same footprint: a 4-1/2 inch by 4-1/2 inch square corner ball bearing hinge, rated medium duty and built for commercial use. The Deltana S45BB shares the 4-1/2 inch by 4-1/2 inch size, square corners and ball bearing construction in steel, but is a residential-rated hinge sold as a pair. On a commercial door with public traffic, the Orca 3535 is the one specified for that service; on an interior residential or light multi-family door, the S45BB carries the same size and prep.

Two Don-Jo heavy weight full mortise ball bearing hinges drop into the same 4-1/2 inch by 4-1/2 inch mortise: the HWBB74545 and the HWBB84545, both heavy duty and both furnished in satin chrome. The Deltana S45BB is a heavy-duty steel ball bearing hinge in the same 4-1/2 inch by 4-1/2 inch size with square corners, full mortise, and is rated residential. Where the specification calls for a heavy weight commercial hinge, the Don-Jo HWBB74545 or HWBB84545 is the one to order against, and the router prep and screw pattern stay in the same size family.

The Stanley Security 2060R is a full mortise spring hinge, square corner, 4-1/2 inch by 4-1/2 inch on a ferrous steel base, rated heavy duty. It occupies the same square corner 4-1/2 inch by 4-1/2 inch full mortise prep the Deltana S45BB uses, and the spring in the barrel returns the leaf. The S45BB is a ball bearing hinge with no closing spring, so a door hung on it stays wherever it is left; pick the 2060R when the leaf has to shut on its own.

No, it is a mechanical steel ball bearing hinge with no conductor in it. For a powered leaf, the Command Access ETH-BB68 is a heavy duty 5 knuckle energy transfer hinge on a steel base, and the Stanley CECB1900R54L is a 3 knuckle concealed bearing concealed conductor hinge, steel full mortise, standard weight, 4-1/2 inch by 4-1/2 inch square corner, left-handed, 4-wire. The Stanley matches the 4-1/2 inch square corner prep the S45BB uses, so on that opening the hinge cutout carries over and the wiring is what gets added.

For a 4 inch square corner prep, the Delaney CH401X is a 4 inch by 4 inch commercial ball bearing hinge with square corners, which keeps the ball bearing construction of the Deltana S45BB at the smaller leaf. The Orca 4040 Series is 4 inch by 4 inch square corner as well, though it is a plain bearing commercial hinge rather than ball bearing. The S45BB is a 4-1/2 inch by 4-1/2 inch hinge and would require the mortise to be lengthened and the frame reinforcement checked before it would sit flush.

No, the mounting is different. The Hager 1129 is a half mortise plain bearing commercial hinge, 4-1/2 inch, standard weight steel, and half mortise means one leaf mortises into the door while the other surface applies to the frame, so it is meant for a channel iron or angle frame. The Deltana S45BB is full mortise, with both leaves let into the door and the frame. Ordering the 1129 for an opening prepped for the S45BB leaves you with a leaf that has nowhere to sit.

Ball bearings are what you want on any door that's heavy, gets constant use, or carries a closer, since the bearings take the load off the knuckles and keep the door from sagging or squeaking. The S45BB is ball bearing. On a light interior door that opens a few times a day, a plain bearing hinge is fine and costs less to standardize on, such as the Emtek 92013 heavy duty plain bearing pair in 3-1/2 x 3-1/2 with square corners, or the Ives 1010RP residential plain bearing set of three.

Both screw types are supplied: #12 x 1-1/4 inch wood screws for a wood jamb and door, and #12 x 1/2 inch machine screws for a hollow metal frame with tapped hinge reinforcements. Nothing else is needed for a standard mortise install. Note the S45BB is sold as a pair, so a typical door on three hinges takes two units, and a heavier or taller door on four takes two pairs.

Nine finishes: Polished Brass, Antique Brass, Oil Rubbed Bronze, Brushed Nickel, Antique Nickel, Polished Chrome, Brushed Chrome, Paint Black, and Prime Coat White. The Prime Coat White is the one to order when the hinge gets painted with the door or trim, and Paint Black covers a black-hardware package. If you're standardizing a building, the brass, nickel, bronze, and chrome options cover the common lever and knob finishes.

Full mortise butt hinges like the S45BB are non-handed. The same hinge works on a left hand or right hand door, and the pair carries no swing designation. What you do have to get right is the corner cut, square rather than radius, and the 4-1/2 x 4-1/2 leaf size against your existing pockets.

Size is the same, the build class is not. The S45BB is a steel ball bearing hinge with a .134 leaf, marked heavy-duty within Deltana's residential line. The Don-Jo HWBB84545 and HWBB74545 are heavy weight full mortise ball bearing hinges in 4-1/2 x 4-1/2 rated heavy duty for commercial service. If the opening is a unit door or interior in a residential building, the S45BB is the fit. If it's carrying a closer or seeing traffic all day, go heavy weight.

No. The S45BB is a plain mechanical butt hinge with no wire path through it. To get power or a monitoring signal from frame to door you need an electrified transfer hinge: the Command Access ETH-BB68 is a 5-knuckle heavy duty energy transfer hinge, the ETH-CB70 is the standard weight 3-knuckle version, and the ETM-BB68 adds an integrated door position switch if you also need to monitor the door. BEST's CECB179-12C is a steel full mortise concealed bearing electrified hinge with a 12-wire quick connect.

They are the same construction in a different size. The Emtek 94013 is a heavy duty ball bearing hinge sold as a pair, 3-1/2 inch by 3-1/2 inch with square corners in plated steel. The Deltana S45BB is also a ball bearing steel hinge with square corners sold as a pair, but at 4-1/2 inch by 4-1/2 inch. The mortise depth and screw locations differ with the leaf size, so the 94013 suits a 3-1/2 inch prep and the S45BB a 4-1/2 inch one; they are not interchangeable in the same door without re-routing.

On a door that cycles rarely, a plain bearing hinge covers the job. The Emtek 91013 is a residential plain bearing hinge sold as a pair, 3-1/2 inch by 3-1/2 inch, square corners, plated steel, and the Schlage Residential S3P1010 is a 3-1/2 inch by 3-1/2 inch square corner plain bearing mortise hinge sold three to a pack. The Deltana S45BB carries ball bearings, which are there to keep a heavier or more frequently used leaf swinging smoothly. Match the prep first: those two are 3-1/2 inch, the S45BB is 4-1/2 inch by 4-1/2 inch.

They share the size but not the build. The McKinney SQ3331 is a square barrel 2 knuckle decorative hinge, 4-1/2 inch by 4-1/2 inch, standard duty. The Deltana S45BB is a 4-1/2 inch by 4-1/2 inch square corner ball bearing steel hinge in a heavy-duty build. The SQ3331 is chosen for the look of the square barrel on an exposed opening; the S45BB is chosen for the bearing action on a door that gets used. If the decision is about how the barrel reads on a feature door, the SQ3331 is the one to look at, not a straight swap for the S45BB.

Yes. The Don-Jo HWBB75045 is a heavy weight full mortise ball bearing hinge at 5 inch by 4-1/2 inch in steel with a satin chrome finish, and the HWBB85045 is a 5 inch by 4-1/2 inch heavy weight full mortise ball bearing hinge in brass, also satin chrome. Both are heavy duty. The 5 inch leaf height gives more screw purchase on a tall or wide leaf than the 4-1/2 inch by 4-1/2 inch Deltana S45BB, and the frame mortise has to be cut to the 5 inch height to take them.

The bearing is the visible difference. The Ives 3CB1 is a steel 3 knuckle concealed bearing full mortise hinge rated medium duty, with the bearing hidden inside the knuckle so the barrel reads as a clean cylinder; the 3CB1HW is the heavy weight version of the same 3 knuckle concealed bearing full mortise hinge. The Deltana S45BB is a full mortise steel hinge with an exposed ball bearing between the knuckles and square corners. Both mortise into the door and frame the same way; the choice is the barrel appearance and the duty rating the opening calls for.

They do not. Detention openings take a dedicated hinge: the BEST BB855 is a heavy-duty steel double weight concealed ball bearing prison hinge, the Stanley BB855 is a double weight prison hinge furnished with no holes and not swaged at 5 inch by 6 inch, and the Hager 990 STEEL is a 3 inch by 4 inch full surface prison hinge with a welded tip, heavy duty. The Deltana S45BB is a residential-rated steel ball bearing hinge for indoor doors. Standardize the S45BB across the ordinary interior openings and specify the detention hinge separately where the door has to resist attack.

The Stanley Security FBB191 is a 5 knuckle full mortise standard weight hinge at 4-1/2 inch by 4-1/2 inch, so it lands in the same mortise as the Deltana S45BB, which is 4-1/2 inch by 4-1/2 inch full mortise with square corners in steel. The McKinney MPB79 MacPro is another 5 knuckle standard weight hinge in the same family of full mortise architectural hinges. Confirm the corner shape of the frame prep before ordering, since the S45BB is square corner and the mortise has to agree.

No, the S45BB is a standard ball bearing butt hinge with no spring in it, so the door stays where you leave it. If you need the door to close on its own without hanging a closer, a spring hinge does that job: Stanley Security's 2060R is a full mortise spring hinge in the same 4-1/2 x 4-1/2 size with square corners, which means it goes into the same pocket geometry.
