Deltana S44R4BB 4" x 4" x 1/4" Radius Hinge, Ball Bearings, Residential, Steel (Pair)

The S44R4BB is a 4 x 4 inch full mortise hinge with 1/4 inch radius corners, so it drops into an existing 4 x 4 mortise cut with 1/4 inch rounded corners. That's the corner radius most steel-frame and factory-routed residential doors use. If your existing mortise has square corners or a 5/8 inch radius, the leaf won't seat flush without recutting, and you'd want a hinge cut to that corner instead.

Think twice on an out-swinging exterior door. The S44R4BB has a standard removable pin, not a non-removable pin, so on a door that swings out the pin sits on the exterior and can be driven out. For that opening you want an NRP hinge, and the Hager BB1168 NRP is a non-removable pin full mortise ball bearing hinge. Deltana also specifies the S44 steel hinge for indoor applications, so an in-swinging interior or entry door where the barrel is on the protected side is where it belongs.

The Deltana S44R4BB is cut with 1/4 inch radius corners, so it wants a routed radius mortise. For a square corner prep at the same 4 inch by 4 inch size, the Delaney CH401X is a 4 inch x 4 inch commercial ball bearing hinge with square corners, which keeps the ball bearing. The Orca Hardware 4040 Series is also a 4 inch x 4 inch square corner hinge, built as a plain bearing commercial hinge. Corner style has to match the existing mortise or the pocket has to be re-cut, so confirm the prep before ordering either way.

The Deltana S44R4BB is a 4 inch by 4 inch steel hinge with 1/4 inch radius corners and ball bearings. The closest match on corner style and size is the Orca Hardware 4014 Series, a 4 inch x 4 inch x 1/4 inch radius corner commercial hinge. The difference is the bearing: the Orca 4014 is a plain bearing hinge, while the S44R4BB runs ball bearings. If the ball bearing is what matters more than the exact corner radius, the Orca 3535 Series is a ball bearing commercial hinge at 4-1/2 inch x 4-1/2 inch with square corners, which needs a different mortise size and corner prep.

The Deltana S44R4BB is a residential-duty steel hinge. Where the opening calls for a heavy weight hinge, the Don-Jo HWBB74545 is a heavy weight full mortise ball bearing hinge at 4-1/2 inch x 4-1/2 inch in satin chrome, and the Don-Jo HWBB75045 is a heavy weight full mortise ball bearing hinge at 5 inch x 4-1/2 inch in steel with a satin chrome finish. The Ives 3CB1HW is a steel heavy weight concealed bearing full mortise hinge with 3 knuckles. All three are larger or built to a heavier duty level than the S44R4BB, so the jamb and door prep need to suit.

The Deltana S44R4BB is a residential steel hinge described as a value choice for indoor applications. For an exterior residential opening at the same 4 inch size, the Delaney RH45xx is a bulk residential exterior hinge at 4 inch x 4 inch with 5/8 inch radius corners, sold as a pair. Note the corner difference: the Delaney runs a 5/8 inch radius against the S44R4BB's 1/4 inch radius, so the two do not share a mortise prep.

The Deltana S44R4BB is not supplied with a non-removable pin. Where an out-swinging door needs the pin secured, the Hager BB1168 NRP is a non-removable pin full mortise ball bearing hinge rated heavy duty. It keeps the full mortise mounting and the ball bearing of the S44R4BB while adding the NRP feature that the Deltana does not carry.

The S44R4BB is sold as a pair, two hinges. A standard interior door hangs on three hinges, so order two pairs per door and you'll have a spare leaf; a 4 x 4 hinge on a light interior slab is commonly hung on two or three depending on the door weight. Count your openings before you order, because mixing a second finish batch later rarely matches exactly.

Screws are included with the S44R4BB. Deltana furnishes #9 x 1 inch wood screws with the hinge, which is the right length for a wood jamb and a wood door edge. If you're hanging into a steel frame or into an engineered slab with a thin edge, you'll need machine screws or a different fastener instead, since the supplied wood screw won't hold in either.

Not handed. The S44R4BB is a symmetrical full mortise butt hinge with a removable pin, so the same hinge hangs a left hand or right hand door. Just orient the barrel to the swing side and set the leaves. That also means you can stock one part number across a whole building instead of splitting your order by handing, which is the usual reason property managers standardize on a 4 x 4 butt.

Ball bearings sit between the knuckles and carry the load on a rolling surface, so the door swings with less friction and the hinge holds up better under frequent use or on a heavier slab. Plain bearing hinges are metal riding on metal, cheaper and fine on a light, low-traffic interior door, but they wear and start to squeak sooner. The S44R4BB is ball bearing. If a plain bearing is enough for the opening, the Orca 4040 Series is a 4 x 4 square corner plain bearing hinge and the Emtek 91013 is a residential plain bearing pair at 3-1/2 x 3-1/2.

The leaf gauge is .085 inch on the S44 steel hinge. That's the number that decides whether the leaf sits flush in a mortise routed for a different hinge: if your existing mortise was cut for a thicker commercial leaf, the S44 will sit proud of the recess and you'll need a shim behind it to keep the door from binding on the strike side.

The S44R4BB uses ball bearings, which is the feature you are paying for on a door that gets cycled often. On a low-traffic interior opening, a plain bearing hinge does the same job with a simpler barrel: the Emtek 91013 is a residential plain bearing hinge pair at 3-1/2 inch x 3-1/2 inch in plated steel with square corners, and the Schlage Residential S3P1010 is a 3.5 inch x 3.5 inch square corner plain bearing mortise hinge sold in a pack of 3. Both are smaller than the S44R4BB's 4 inch by 4 inch footprint, so they suit a 3-1/2 inch prep rather than a 4 inch one.

They are not the same construction. The Deltana S44R4BB is a full mortise hinge with visible ball bearings between the knuckles. The Ives 3CB1 is a 3-knuckle concealed bearing full mortise hinge rated medium duty, and the Hager 920 is a full mortise concealed bearing hinge with 2 knuckle steel construction, also medium duty. Concealed bearing hinges hide the bearing inside the knuckle and give a smooth barrel profile, so the barrel appearance and knuckle count differ from the S44R4BB even where the mortise mounting method is the same.

No. The S44R4BB is a standard full mortise ball bearing hinge with no spring and no electrical path. For a self-closing opening, the Stanley Security 2060R is a full mortise spring hinge with square corners at 4.5 inch x 4.5 inch on a ferrous steel base. To carry power to an electrified lock through the hinge, the Command Access ETH-CB70 is an energy transfer hinge with a 3 knuckle standard weight steel base, and the Command Access ETM-CB70 adds door position sensing on the same 3 knuckle steel base. Those are function-specific hinges, not finish or size alternatives to the Deltana.

The Deltana S44R4BB is a full mortise hinge, which needs a mortised pocket in both the door edge and the jamb and swings one way. For a double acting commercial interior door, the BEST DAP-3 is a heavy duty double acting pivot. Where only the frame side can be mortised, the Hager 1129 is a half mortise plain bearing commercial hinge at 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. Each of those changes the door and frame prep entirely from a full mortise hinge.

Eight finishes on the S44R4BB: oil rubbed bronze, brushed nickel, antique nickel, polished chrome, brushed chrome, polished brass, brushed brass, and antique brass. That spread covers most of what's already hanging in a residential building, so matching hinges to existing levers and pulls across a set of units is usually possible without changing hinge models. The base metal underneath is steel in every case, so the finish is plated over steel rather than solid brass.

The S44R4BB uses an arc hole pattern, the staggered arrangement standard on residential butt hinges, rather than a straight line of holes. If the hinge coming off the door is also a 4 x 4 residential butt with an arc pattern, the holes usually land close enough to reuse the mortise. Commercial hinges often run a different pattern, so on a swap from a commercial hinge plan on drilling fresh pilot holes.

The Deltana S44R4BB is sold by the pair, so a standard three-hinge door takes two orders' worth or a second pair. The Ives 1010RP steel plain bearing residential hinge with square corners is sold as a set of 3, and the Schlage Residential S3P1010 3.5 inch x 3.5 inch square corner plain bearing mortise hinge comes in a pack of 3. The Emtek 94013 heavy duty ball bearing hinge and the Delaney RH45xx exterior residential hinge are both sold as pairs like the Deltana. Count the leaves per door before you set quantity.
