Deltana S44R4-BT Steel Hinge with Ball Tips, 4" x 4" x 1/4" Radius Corners (Pair)

Radius, 1/4 inch on all four corners. That matters because the corner cut has to match the mortise already routed in your door and jamb. If the existing hinges pull out with square corners, or a 5/8 inch radius (common on residential prehung doors), the S44R4-BT will not sit in the pocket without recutting. Measure the old hinge leaf corner before you order.

The pin is removable, not NRP. On an out-swinging exterior door the barrel sits outside, so a removable pin means the door can be lifted off once the pin is driven out. Deltana specs this steel hinge for indoor use. For an opening that needs a fixed pin, the Hager BB1168 is a heavy duty full mortise ball bearing hinge supplied with a non-removable pin.

Leaf thickness is .085 inches. Compare that to the hinges coming off the door: if the old leaf is thinner, the door will sit proud of the jamb and may bind at the strike side, and if it is thicker you will have a gap behind the leaf. It is a full mortise hinge, so both leaves recess, one into the door edge and one into the jamb.

The S44R4-BT is cut with 1/4" radius corners, so it will not sit correctly in a square-corner mortise without rework. For a square-corner 4" x 4" prep, the Orca Hardware 4040 Series is a 4" x 4" square corner plain bearing commercial hinge in medium duty, and the Delaney CH401X is a 4" x 4" commercial ball bearing hinge with square corners. Both keep the 4 inch leaf size; the Orca stays plain bearing like the Deltana, while the Delaney moves to ball bearing.

The Orca Hardware 4014 Series is a 4" x 4" x 1/4" radius corner plain bearing commercial hinge, which matches the Deltana S44R4-BT on size, corner style, and plain bearing type. The difference is duty level and dress: the Orca 4014 is rated medium duty and built as a commercial hinge, while the S44R4-BT is a residential steel hinge with matching ball tips installed. On an existing 4" x 4" mortise with 1/4" radius corners, either drops into the same prep, so the choice comes down to whether the opening wants a decorative tip or a commercial-duty body.

The S44R4-BT is a residential plain bearing hinge, so a busy commercial opening is better served by a bearing hinge built for the cycle count. The Ives 3CB1HW is a steel heavy weight concealed bearing full mortise hinge with 3 knuckles rated heavy duty, and the Don-Jo HWBB84545 is a heavy weight full mortise ball bearing hinge in 4-1/2" x 4-1/2" steel. Note the size change: the Don-Jo is 4-1/2" x 4-1/2", not the 4" x 4" of the Deltana, so the frame and door prep have to accept the larger leaf.

They are close in class but not interchangeable. The Emtek 91013 is a residential plain bearing hinge sold as a pair in plated steel, matching the Deltana S44R4-BT on plain bearing type, steel material, and pair packaging. The differences are size and corner: the Emtek 91013 is 3-1/2" x 3-1/2" with square corners, while the S44R4-BT is 4" x 4" with 1/4" radius corners. A door mortised for one will not take the other without recutting.

No. The S44R4-BT is a residential full mortise steel hinge supplied with a removable pin, since it is not a non-removable pin hinge. Openings written for security hardware call for something like the Hager BB1168 non-removable pin full mortise ball bearing heavy duty hinge, or, for detention work, the BEST BB855 heavy-duty steel double weight concealed ball bearing prison hinge or the Hager 990 STEEL full surface prison hinge 3" x 4" with welded tip. Those are different hinge classes, and the Hager 990 is full surface rather than full mortise.

It does not. The S44R4-BT is a plain steel hinge with ball tips and no conductor path. For power transfer through the hinge, the Command Access ETH-CB70 is an energy transfer hinge with a 3 knuckle standard weight steel base in medium duty, and the ETH-BB68 is the 5 knuckle heavy duty steel base version. If the door also needs position monitoring, the Command Access ETM-CB70 adds door position sensing on a 3 knuckle steel base, and the BEST CECB179-12C is a steel full mortise concealed bearing electrified hinge with a 12-wire quick connect. All are full-size commercial hinges, so the frame prep differs from a residential 4" x 4".

For a 3-1/2 inch prep, the Orca Hardware 3514 Series is a 3.5" x 3.5" x 1/4" radius corner plain bearing commercial hinge, which keeps both the 1/4" radius corner and the plain bearing of the S44R4-BT at the smaller leaf. On residential doors, the Schlage Residential S3P1010 is a 3.5" x 3.5" square corner plain bearing mortise hinge sold in a pack of 3, and the Delaney RH35xx is a 3-1/2" x 3-1/2" bulk steel residential interior hinge pair with 5/8" radius corners. The corner cut differs across the three, so match it to the existing mortise.

Yes, wood screws are furnished, #10 x 1 inch. That length is sized for wood jambs and door stiles. On a hollow metal frame or where the jamb is shimmed off the stud, you will want longer screws into framing instead, since a 1 inch wood screw only bites the jamb board.

Oil rubbed bronze is one of seven finishes offered: oil rubbed bronze, brushed nickel, antique nickel, polished chrome, brushed chrome, polished brass, and antique brass. The ball tips come installed in the matching finish, so the decorative tip is not a separate order line.

Plain bearing, like the S44R4-BT, has the knuckles riding directly on each other. It is quiet and fine for a residential interior door that gets opened a handful of times a day. Ball bearing hinges put bearings between the knuckles to carry weight and cycles, which is what you want on a heavy door, a door with a closer on it, or a high-traffic opening. If that is your situation, look at the Emtek 94013 heavy duty ball bearing hinge or the Don-Jo HWBB74545 heavy weight full mortise ball bearing hinge in 4-1/2 x 4-1/2.

The ball tips on the S44R4-BT are a decorative option, and if the opening does not call for them the Delaney RH40xx is a 4" x 4" residential hinge pair for Castlegate in 5/8" radius by square, and the Delaney RH45xx is a 4" x 4" bulk residential exterior hinge pair with 5/8" radius corners. Both hold the 4" x 4" leaf size but use a 5/8" radius corner rather than the 1/4" radius of the Deltana, so confirm which radius the existing mortise was cut to before ordering.

Both are chosen partly for how they look. The S44R4-BT is a 4" x 4" steel hinge whose decoration is the matching ball tips, offered in Oil Rubbed Bronze, Brushed Nickel, Antique Nickel, Polished Chrome, Brushed Chrome, Polished Brass, and Antique Brass. The McKinney SQ3331 is a square barrel 2-knuckle decorative hinge at 4-1/2" by 4-1/2" in standard duty, so its look comes from the square barrel profile and it uses a larger leaf and a 2-knuckle barrel rather than a tipped knuckle stack.

They are both full mortise hinges, so they mount the same way, but they are not the same product. The Ives 3CB1 is a steel 3-knuckle concealed bearing full mortise hinge rated medium duty, where the bearings sit hidden inside the knuckles; the S44R4-BT is a plain bearing residential hinge finished with ball tips. The Hager 920 is another concealed option, a full mortise concealed plain bearing hinge with 2-knuckle steel construction in medium duty. Confirm leaf size and corner cut against the existing prep before swapping, since the S44R4-BT is 4" x 4" with 1/4" radius corners.

No, they mount differently. The S44R4-BT is a full mortise hinge, meaning both leaves recess into the door and frame. The Hager 1129 is a half mortise plain bearing commercial hinge at 4-1/2" standard weight steel, which mortises into the door but fastens to the face of the frame, and the Hager 990 STEEL is a full surface prison hinge that fastens to the faces of both. Those are chosen for channel-iron or metal frames that cannot be routed, not as a drop-in for a routed 4" x 4" mortise.

Stepping up from the residential S44R4-BT, the Emtek 92013 is a heavy duty plain bearing hinge pair in plated steel that keeps the plain bearing arrangement, and the Emtek 94013 is the heavy duty ball bearing version, also sold as a pair. Both are 3-1/2" x 3-1/2" with square corners, so they are a smaller leaf and a different corner cut than the 4" x 4" 1/4" radius Deltana. For a 4 inch leaf on a heavier commercial door, the Ives 3CB1HW is a steel heavy weight concealed bearing full mortise hinge.

The S44R4-BT is the decorative option: steel hinge with ball tips installed in the matching finish, which is what you use when the hinge is visible and has to match the lever and the rest of the trim. If the hinges are painted over or hidden behind casing and nobody is looking at them, a plain residential hinge does the same job without the tip cost. The Ives 1010RP is a plain bearing residential hinge with square corners that ships three to a set, which matches one door exactly.

Steel, both the base material and the substrate, with the finish applied over it. If the opening is exposed to moisture, a bathroom, a pool corridor, a coastal exterior, steel is the wrong base and you want a non-ferrous hinge instead. The McKinney T2314 is a non-ferrous standard weight 5-knuckle hinge that covers that case.
