Deltana DSB4R5-RZ 4" x 4" x 5/8" Radius Hinges, Zig-Zag (Pair)

The DSB4R5-RZ measures 4 inches by 4 inches with 5/8 inch radius corners, which is the standard residential rounded-corner mortise routed by most door prep templates. If the pockets on your door and jamb are 4 x 4 with rounded corners, pull an old hinge and check the corner radius: a 1/4 inch radius pocket is tighter than this hinge and a square-corner pocket will leave gaps at the corners. Full mortise mounting, so both leaves recess into the door edge and the frame.

No. These are plain bearing solid brass hinges rated residential, so an office entry, a stairwell door, or anything on a closer and heavy daily traffic will wear the knuckles out. For that traffic go to a ball bearing commercial hinge such as the Orca Hardware 4040 Series 4 x 4 square corner or the Don-Jo HWBB84545 heavy weight 4-1/2 x 4-1/2. The Deltana is the right choice for interior and residential doors where the brass finish is part of the look.

No NRP on the DSB4R5-RZ, so the pin can be driven out from the hinge side. On an outswing door where the barrels are exposed outside, that is a security concern. For that opening use a hinge with a non-removable pin such as the Hager BB1168 NRP full mortise ball bearing hinge.

The Deltana DSB4R5-RZ is a 4 inch by 4 inch pair with 5/8 inch radius corners, rated residential, in solid brass. The Delaney DLY-RH45xx is also a 4 inch by 4 inch residential pair with 5/8 inch radius corners, sold in the Exterior Residential Hinges series, so the corner radius drops into the same factory-prepped jamb without re-routing. The Delaney DLY-RH40xx is a 4 inch by 4 inch residential pair furnished 5/8 inch radius by square, which pairs one radius leaf with one square leaf for a door and jamb prepped differently. The Deltana is brass; the Delaney hinges are steel, so match the finish family before mixing them on the same opening.

The Deltana DSB4R5-RZ is furnished with 5/8 inch radius corners, which will leave a gap at the corners of a square mortise. The Orca Hardware ORC-COM4040 is a 4 inch by 4 inch square corner plain bearing hinge in the 4040 series, the same leaf size and the same plain bearing action, so it fills a square prep without patching. If the frame is prepped for a tighter radius rather than a true square, the Orca ORC-COM4014 is a 4 inch by 4 inch hinge with 1/4 inch radius corners. Confirm the corner radius on the existing mortise before ordering, since 1/4 inch and 5/8 inch are not interchangeable.

The Deltana DSB4R5-RZ is a plain bearing hinge rated residential, which suits apartment interiors and light-use openings. For a commercial opening cycling all day, a ball bearing hinge carries the load differently: the Orca Hardware ORC-COM3535 is a 4-1/2 inch by 4-1/2 inch square corner ball bearing commercial hinge rated medium duty, and the Delaney DLY-CH401X is a 4 inch by 4 inch commercial ball bearing hinge with square corners, which keeps the same 4 inch by 4 inch leaf size as the Deltana. For heavier doors, the Don-Jo DON-HWBB74545-652 is a heavy weight full mortise ball bearing hinge at 4-1/2 inch by 4-1/2 inch in satin chrome. Note the 4-1/2 inch options need a wider mortise than a 4 inch by 4 inch prep.

The Deltana DSB4R5-RZ is furnished without a non-removable pin, so on an out-swinging exterior door the pin stays accessible from the outside. The Hager HAG-BB1168 -NRP is a non-removable pin full mortise ball bearing hinge rated heavy duty in the BB1168 series, which addresses that opening directly. It is a heavy duty ball bearing hinge where the Deltana is a residential plain bearing hinge, so verify the frame prep and leaf size against the existing mortise before swapping.

Zig-zag means the screw holes are staggered rather than run in a straight line down the leaf. Staggering keeps the #10 x 1 inch wood screws from splitting the grain along one line in a wood door edge or jamb, which is why it is the residential pattern. It also means the DSB4R5-RZ will not line up with existing screw holes drilled to an inline pattern, so plan on new pilot holes.

Sold by the pair, and a standard interior door hangs on three hinges, so order two pairs per door and you will have a spare leaf set, or count pairs across the job and round up. Tall or heavier doors take four. Each pair ships with #10 x 1 inch wood screws.

Yes, the DSB4 solid brass hinges accept Deltana decorative finials, which is the usual reason to spec these over a plain steel residential hinge. The finials are ordered separately and matched to the hinge finish.

Leaf thickness is .085 inches on the solid brass DSB4R5-RZ. That figure is what decides whether the hinge sits flush in an existing mortise: a deeper pocket cut for a thicker commercial leaf will leave the hinge proud of nothing, but a shallower residential pocket may need a light pass to seat it, and going too deep pulls the door tight against the stop.

The Delaney 4 x 4 bulk residential exterior hinge carries the same 5/8 inch radius corner in a steel pair, and the Delaney 4 x 4 Castlegate pair comes 5/8 inch radius by square if you are matching one radius pocket to one square pocket. Both drop into the same 4 x 4 radius-corner prep the Deltana uses, so it is a straight swap on the mortise if you do not need solid brass.

Neither. The DSB4R5-RZ is a plain bearing residential hinge with no wire path through the barrel. If you need power to the lock or a monitored opening, use an electrified hinge such as the Command Access ETH-CB70 energy transfer hinge or the ETM-CB70, which adds door position sensing.

Not on the same opening. The Deltana DSB4R5-RZ is a residential plain bearing hinge in solid brass, 4 inch by 4 inch with 5/8 inch radius corners. The Ives 3CB1 is a 3-knuckle concealed bearing full mortise hinge rated medium duty, and the McKinney MCK-MP79 MacPro is a 5-knuckle full mortise hinge rated standard weight. Those are steel commercial hinges with different bearing construction and knuckle counts, and they carry the door differently than a plain bearing brass hinge. If the drawing calls out a concealed bearing commercial hinge, order the Ives 3CB1 or Ives 3CB1HW, which is the heavy weight concealed bearing version, rather than substituting the Deltana.

No. The Deltana DSB4R5-RZ is a mechanical solid brass hinge with a plain bearing and no wiring path. If the opening needs power transferred to an electrified lock, the Command Access CAT-ETH-CB70 is a 3-knuckle standard weight energy transfer hinge on a steel base, and the BEST BEST-CECB179-12C is a steel full mortise concealed bearing electrified hinge with a 12-wire quick connect rated medium duty. If the opening also needs door position reporting, the Command Access CAT-ETM-CB70 is an energy transfer monitor hinge with door position sensing on a 3-knuckle steel base. Those replace one hinge in the set; the remaining hinges on the door can stay mechanical.

No. The Deltana DSB4R5-RZ is a plain bearing full mortise hinge with no spring in the barrel, so the door stays where it is left. For a self-closing opening, the Stanley Security STN-2060R 4.5 X 4.5 is a full mortise spring hinge with square corners at 4.5 inch by 4.5 inch on a ferrous steel base, rated heavy duty. It is a 4-1/2 inch square corner hinge, so the 4 inch by 4 inch radius mortise the Deltana fits will need to be re-cut to take it.

No. The Deltana DSB4R5-RZ is a residential solid brass hinge with a plain bearing and a removable pin. Detention openings call for hinges built for that use: the BEST BEST-BB855 is a heavy-duty steel double weight concealed ball bearing prison hinge in the Detention Hardware series, the Stanley STN-BB855 is a double weight prison hinge at 5 inch by 6 inch furnished no holes and not swaged, and the Hager HAG-990 STEEL is a full surface prison hinge 3 inch by 4 inch with a welded tip, rated heavy duty. Those mount and prep differently from a 4 inch by 4 inch full mortise residential hinge.

Eleven finishes: PVD Polished Brass, Polished Brass, Unlacquered Brass, Antique Brass, Polished Nickel, Brushed Nickel, Antique Nickel, Polished Chrome, Brushed Chrome, Oil Rubbed Bronze, and Paint Black. If you are matching a whole floor of doors, the PVD Polished Brass holds its color where standard lacquered polished brass will wear, and Unlacquered Brass is the one that will patina on purpose over time.

Not handed. A full mortise butt hinge with a removable pin works either swing, so one part number covers both left and right hand doors. Order by size and finish only.

Both are chosen partly for looks, but they differ in construction. The Deltana DSB4R5-RZ is solid brass with 5/8 inch radius corners, a zig-zag hole pattern, and comes in finishes including polished brass, oil rubbed bronze, polished nickel, and unlacquered brass. The McKinney MCK-SQ3331 is a square barrel 2-knuckle decorative hinge at 4-1/2 inch by 4-1/2 inch rated standard duty, so its barrel profile is square rather than round and its leaf is a half inch larger in both directions. Match the barrel style to the other doors before mixing the two in one house.
