Deltana DSB4-RZ 4" x 4" Square Hinges, Residential / Zig-Zag (Pair)

These are residential-duty, plain bearing hinges. Plain bearing means metal-on-metal at the knuckle rather than a bearing race, which is fine for interior passage and bedroom doors but not for a heavy or high-traffic leaf. For a commercial opening or a heavy exterior door, move to a ball bearing hinge such as the Orca Hardware 3535 Series 4-1/2 x 4-1/2 square corner ball bearing commercial hinge or the Don-Jo HWBB84545 heavy weight 4-1/2 x 4-1/2.

DSB4-RZ is sold as a pair, so one order covers two of the three hinges a standard 6 foot 8 inch door carries. For a full door, order two pairs and you will have a spare leaf set. If you would rather buy in threes, the Ives 1010RP residential plain bearing hinge ships as a set of 3 and the Schlage Residential S3P1010 comes in a pack of 3.

No. The DSB4-RZ does not carry the NRP option, so the pin can be driven out from the hinge side. On an out-swing exterior or a tenant-facing door where the knuckles are exposed outside, that is a security gap, and you want a non-removable pin hinge instead, such as the Hager BB1168 NRP full mortise ball bearing hinge.

Not on the same door prep. Both are residential plain bearing hinges sold as a pair with square corners, but the Emtek 91013 is 3-1/2 inch by 3-1/2 inch and the Deltana DSB4-RZ is 4 inch by 4 inch, so the mortise size differs by half an inch in each direction. The Emtek 91013 is plated steel and the Deltana is solid brass. Use the Emtek where the door is already prepped for a 3-1/2 inch hinge, not as a drop-in for a 4 inch pocket.

The Deltana DSB4-RZ is designated residential with a plain bearing. For commercial traffic at the same 4 inch by 4 inch size, the Delaney 4 inch by 4 inch Commercial Ball Bearing Hinge has square corners and a ball bearing knuckle, and the Orca Hardware 4040 Series is a 4 inch by 4 inch square corner commercial hinge rated medium duty. Ball bearing knuckles are the usual choice where the door cycles all day; plain bearing is the usual choice on a bedroom or interior residential door.

The Deltana DSB4-RZ has square corners, so it needs a square routed mortise or a chiseled pocket. For a 1/4 inch radius corner pocket, the Orca Hardware 4014 Series is a 4 inch by 4 inch 1/4 inch radius corner plain bearing hinge, medium duty. For a 5/8 inch radius pocket in a residential exterior door, the Delaney 4 inch by 4 inch Bulk Residential Hinges Exterior are a 5/8 inch radius pair. Match the corner radius to what is already routed in the door and jamb and you avoid re-prepping either one.

The Deltana DSB4-RZ is not a non-removable pin hinge. On an out-swinging door where the barrel is on the outside, specify a hinge built for it: the Hager BB1168 is a non-removable pin full mortise ball bearing heavy duty hinge. Keep the Deltana for in-swinging and interior openings where the pin is on the protected side.

No. The Deltana DSB4-RZ is a plain mechanical hinge with no wiring path. To carry power through the hinge to an electric lock, use an energy transfer hinge such as the Command Access ETH-CB70, a 3 knuckle standard weight steel base transfer hinge rated medium duty, or the BEST CECB179-12C steel full mortise concealed bearing electrified hinge with a 12-wire quick connect. If the door also needs position monitoring, the Command Access ETM-CB70 adds door position sensing on a 3 knuckle steel base.

Zig-zag means the screw holes are staggered across the leaf rather than lined up in a single row. Staggered holes put each #10 x 1 inch wood screw into a different grain line of the stile, which reduces splitting on a wood jamb. It also means the hole layout will not necessarily line up with an existing in-line-drilled hinge, so plan on fresh pilot holes.

Solid brass through the whole leaf, not plated steel, so there is no ferrous core to bleed rust if the finish gets scratched or the door sees weather. That is the practical reason to spend up on brass over a plated steel residential hinge like the Emtek 91013. Bear in mind the bearing is plain, not ball, so a heavy solid-core exterior slab is still better served by a bearing hinge.

Seven finishes on the DSB4-RZ: oil rubbed bronze, polished brass, unlacquered brass, polished nickel, brushed nickel, polished chrome, and paint black. Unlacquered brass is the one to note if you are matching a fleet, since it will patina over time rather than holding its as-shipped color, while the lacquered and plated finishes stay put. For a building standard, pick one finish and stay on the DSB4 series across the openings.

Leaf thickness is .085 inch, which is a residential gauge, and the hinge is rated residential with a plain bearing. It will hang a normal hollow core or light solid core interior door on 4 inch leaves. For a heavy solid core or a door with a closer on it, step to a bearing hinge in a larger leaf, like the Don-Jo HWBB75045 at 5 x 4-1/2.

Both are residential plain bearing hinges with square corners. The Ives 1010RP is steel, medium duty, in the 1000 series, and is sold as a set of three; the Deltana DSB4-RZ is solid brass and is sold as a pair. On a standard interior door hung on three hinges, the Ives set covers one door in a single order while the Deltana is ordered by the pair. The Deltana also uses a zig-zag hole pattern, which stagggers the screws in the leaf.

The Deltana DSB4-RZ is a standard full mortise hinge and does not close the door on its own. Where the opening needs the door to return closed, the Stanley Security Spring Hinge is a full mortise square corner spring hinge at 4-1/2 inch by 4-1/2 inch on a ferrous steel base, heavy duty. The size step from 4 inch to 4-1/2 inch means the mortise has to be enlarged in both the door and the jamb.

The Deltana DSB4-RZ is a residential plain bearing hinge. For a heavier leaf, the Don-Jo HWBB74545 is a heavy weight full mortise ball bearing hinge at 4-1/2 inch by 4-1/2 inch in satin chrome, and the Ives 3CB1HW is a steel heavy weight concealed bearing full mortise hinge with 3 knuckles, rated heavy duty. Both step up to a larger leaf than 4 inch by 4 inch, so plan on a larger mortise in the door and jamb.

They mount differently. The Deltana DSB4-RZ is a full mortise hinge, with both leaves let into the door and the jamb. The Hager 1129 is a half mortise plain bearing commercial hinge, 4-1/2 inch standard weight steel, rated heavy duty, which mortises into the door and surface applies to the frame. Half mortise is used where the frame cannot be routed, typically a channel iron or hollow metal frame, so it is not an exchange for a wood door prepped full mortise.

No. The Deltana DSB4-RZ is a residential plain bearing hinge in solid brass without a non-removable pin. Detention openings use purpose built hardware: the BEST BB855 is a heavy duty steel double weight concealed ball bearing prison hinge in the Detention Hardware series, and the Hager 990 STEEL is a full surface prison hinge 3 inch by 4 inch with a welded tip, heavy duty. Those are a different mount and a different weight class from a 4 inch residential brass hinge.

Yes, the solid brass DSB4 hinges accept decorative finials at the pin ends, which is why they get specified on visible openings in restoration and high-end residential work where a plain steel hinge would look wrong. Finials are ordered separately from the hinge pair.

Full mortise butt hinges like the DSB4-RZ are symmetrical and non-handed, so the same pair hangs a left-hand or right-hand door. You flip the hinge, not the part number. Ordering by hand only comes up on electrified and specialty hinges, the way the Stanley CECB1900R54L is called out as left-handed.

The DSB4-RZ pair is furnished with #10 x 1 inch wood screws. That length is sized for wood jambs and door stiles. If you are hanging into a hollow metal frame, machine screws and tapped frame holes are a different fastener entirely and the wood screws supplied will not hold.

The Delaney 4 inch by 4 inch Residential Hinges for Castlegate are in the Castlegate Hinges series and come as a 5/8 inch radius by square pair, matched to that door line. The Deltana DSB4-RZ is a 4 inch by 4 inch solid brass square corner pair with a zig-zag hole pattern. Same leaf size either way; the corner profile is what decides which one drops into the pocket you already have.
