Deltana DSB4R4-RZ 4" x 4" x 1/4" Radius Hinges, Zig-Zag (Pair)

The DSB4R4-RZ measures 4 x 4 inches with 1/4 inch radius corners, so it drops into an existing 4 inch mortise only if that mortise was routed with 1/4 inch radius corners. Most prehung residential doors are cut with 5/8 inch radius corners instead, and a 1/4 inch radius leaf will leave a visible gap at the corners of a 5/8 inch pocket. Check the corner radius of what is coming off the door before ordering.

They ship with a standard removable pin, not an NRP (non-removable pin) hinge, so on an out-swinging exterior door the pins are accessible from outside. For an out-swing exterior or any security-sensitive opening, use a hinge with a non-removable pin such as the Hager BB1168-NRP. On an in-swinging door the pin is on the protected side and this is not an issue.

No. At 4 x 4 inches these are a full half inch larger in both directions than the 3-1/2 x 3-1/2 hinges common on interior residential doors, so they will not drop into a 3-1/2 inch mortise without re-routing. If your other openings are running 3-1/2 inch, you would match with a 3-1/2 hinge like the Orca 3514 Series (also 1/4 inch radius corner) or the Emtek 91013 residential pair in square corner.

Plain bearing is the right call for lighter interior and residential doors that are not cycled constantly, and that is what the DSB4R4-RZ is built as. Ball bearing hinges carry more weight and handle high cycle counts without wearing the knuckle, which is why they show up on commercial and heavy solid-core doors. If you are hanging a heavy solid-core or a door with a closer on it, go ball bearing, for example the Emtek 94013 heavy duty ball bearing pair or the Don-Jo HWBB74545 at 4-1/2 x 4-1/2.

The Orca Hardware 4014 Series is a 4 inch by 4 inch hinge with 1/4 inch radius corners and a plain bearing, the same size, corner style and bearing type as the Deltana DSB4R4-RZ. The differences are in material and intended use: the Deltana DSB4R4-RZ is solid brass and designated residential, while the Orca 4014 Series is a commercial hinge rated medium duty. On an opening where the 1/4 inch radius mortise is already routed, either drops into the same prep.

The Deltana DSB4R4-RZ is cut with 1/4 inch radius corners, so it will not seat cleanly in a square corner mortise. For a 4 inch by 4 inch square corner prep, the Orca Hardware 4040 Series is a 4 inch by 4 inch square corner plain bearing hinge, and the Delaney CH401X is a 4 inch by 4 inch commercial ball bearing hinge with square corners. Both match the 4 inch by 4 inch leaf size of the Deltana.

Yes. The Deltana DSB4R4-RZ is solid brass and sold as a pair for residential use. In steel, the Delaney RH45xx is a 4 inch by 4 inch bulk residential exterior hinge pair with 5/8 inch radius corners, and the Delaney RH40xx is a 4 inch by 4 inch residential hinge pair for Castlegate doors in 5/8 inch radius by square. The corner radius differs from the Deltana's 1/4 inch, so the mortise must match.

The Deltana DSB4R4-RZ is a 4 inch by 4 inch hinge and will not fit a 3-1/2 inch mortise. For 3-1/2 inch by 3-1/2 inch openings, the Orca Hardware 3514 Series carries the same 1/4 inch radius corner and plain bearing arrangement in a commercial medium duty hinge. In residential square corner, the Emtek 91013 is a 3-1/2 inch by 3-1/2 inch plated steel plain bearing pair 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 DSB4R4-RZ is designated residential with a plain bearing. For heavier commercial traffic, the Don-Jo HWBB84545 is a heavy weight full mortise ball bearing hinge at 4-1/2 inch by 4-1/2 inch, the Ives 3CB1HW is a steel heavy weight concealed bearing full mortise hinge with 3 knuckles, and the Hager BB1168 is a heavy duty full mortise ball bearing hinge supplied with a non-removable pin. All three are larger or different in prep than the 4 inch by 4 inch Deltana, so the mortise and screw pattern should be verified.

The Deltana DSB4R4-RZ is supplied without a non-removable pin. Where the pin needs to be secured on an outswing door, the Hager BB1168 is a non-removable pin full mortise ball bearing heavy duty hinge. It is a different construction from the 4 inch by 4 inch solid brass Deltana, so confirm leaf size and corner prep against the existing mortise.

Zig-zag means the screw holes are staggered rather than lined up in a single row down the leaf. The stagger puts each screw into a different grain line so the wood is less likely to split, which is why it is the residential wood-door pattern. If your existing hinge has holes in a straight line, you will be drilling fresh pilot holes rather than reusing the old ones.

Wood screws are specified as #10 x 1 inch, and no machine screws are supplied since this is a wood-door hinge rather than a metal-frame one. Sold by the pair, so a standard door taking three hinges needs two pairs (you will have one spare) or one pair plus a single.

Ten finishes: PVD Polished Brass, Polished Brass, Antique Brass, Oil Rubbed Bronze, Polished Nickel, Brushed Nickel, Antique Nickel, Polished Chrome, Brushed Chrome, and Paint Black. The PVD Polished Brass is the one to specify if you want the brass tone to hold up without tarnishing, which matters on exterior-facing or high-touch doors where a lacquered brass will wear through.

Solid brass through the body, not a plated steel base. That is the practical difference between the DSB4 Series and residential hinges like the Emtek 91013, which is a plated steel plain bearing hinge. Solid brass will not rust if the finish wears, which is why it gets specified on humid or coastal jobs, and it is the reason the leaf can be finished in ten different platings.

Yes, it is a full mortise hinge, meaning both leaves recess into routed pockets, one in the door edge and one in the jamb, so the leaves sit flush and only the barrel shows when the door is closed. If your frame cannot be mortised, a full mortise hinge is the wrong mounting type and you would be looking at a half mortise or full surface hinge instead.

Several full mortise hinges in the same size range serve a different purpose entirely. The Command Access ETH-CB70 and ETM-CB70 are energy transfer hinges that carry power through the hinge, and the ETM versions add door position sensing, so they require an electrified opening. The BEST CECB179-12C is a steel full mortise concealed bearing electrified hinge with a 12-wire quick connect. The Stanley 2060R is a spring hinge that provides self-closing action. The BEST BB855 and Stanley BB855 are double weight prison hinges. The Deltana DSB4R4-RZ is a plain bearing solid brass hinge with no electrified, spring or detention function, so none of those substitute for it.

The Deltana DSB4R4-RZ is solid brass and offered in ten finishes including PVD Polished Brass, Oil Rubbed Bronze, Polished Nickel, Brushed Nickel, Antique Nickel, Polished Chrome, Brushed Chrome, Polished Brass, Antique Brass and Paint Black, which is why it is used where the hinge shows. Another decorative option is the McKinney SQ3331, a square barrel 2-knuckle decorative hinge at 4-1/2 inch by 4-1/2 inch rated standard duty. The SQ3331 is the larger leaf size and a square barrel profile rather than the Deltana's standard barrel.

The Deltana DSB4R4-RZ is a full mortise hinge, meaning both leaves mortise into the door and frame. Where the frame cannot be mortised, the Hager 1129 is a half mortise plain bearing commercial hinge in 4-1/2 inch standard weight steel, and the Hager 990 STEEL is a full surface hinge at 3 inch by 4 inch with a welded tip. Neither shares the Deltana's prep, so the opening determines which applies.

The Deltana DSB4R4-RZ is a full mortise plain bearing hinge at 4 inch by 4 inch with 1/4 inch radius corners, sold in pairs. For a fleet of similar interior doors, the Orca Hardware 4014 Series matches the 4 inch by 4 inch 1/4 inch radius plain bearing configuration in a medium duty commercial hinge, the Orca 4040 Series covers the same size in square corner plain bearing, and the Ives 1010RP is a steel plain bearing residential hinge with square corners supplied as a set of three for doors needing a third hinge. Corner profile is the deciding detail when mixing these across existing preps.

Yes, the DSB4 Series solid brass hinges accept decorative finials, so you can swap the standard tips for ball, steeple, or urn tips to match the rest of the trim on a period or high-end residential door. The finials are a separate order item.
