Deltana DSB4R5N 4" x 4" x 5/8" Radius Hinges, NRP (Pair)

Yes, if the existing mortise is a 4 inch by 4 inch cutout with 5/8 inch radius corners. The DSB4R5N is a 4 x 4 full mortise hinge with 5/8 inch radius corners, which is the standard router-cut corner on most residential prehung doors. If your existing mortise has square corners, the radius leaf will leave a small gap at each corner and you would want a square corner hinge instead.

NRP is a non-removable pin. A set screw in the barrel seats against the pin once the door is closed, so the pin cannot be driven out from the hinge side. It matters on any out-swinging exterior door, where the hinge barrels are exposed on the outside of the opening. On an in-swinging door the barrels are inside and NRP is optional. The DSB4R5N is supplied with NRP as standard.

No. It's a residential-duty plain bearing hinge, so it suits entry doors, interior passage doors and similar household traffic. For an office, school or apartment common door you want a ball bearing or concealed bearing commercial hinge, such as the Orca Hardware 4040 Series 4 x 4 square corner plain bearing commercial hinge, the Orca 4014 Series 4 x 4 with 1/4 inch radius corners, or the Ives 3CB1HW heavy weight concealed bearing full mortise hinge.

The DSB4R5N is a 4 inch by 4 inch solid brass full mortise hinge with a non-removable pin and 5/8 inch radius corners, built on a plain bearing and rated for residential use. For a commercial steel frame, the Hager BB1168-NRP is a full mortise ball bearing hinge that also carries a non-removable pin and is listed heavy duty. The difference is the bearing and duty level: plain bearing brass in residential duty versus a heavy duty ball bearing hinge.

Yes. The Delaney RH45xx is a 4 inch by 4 inch residential exterior hinge with 5/8 inch radius corners sold in pairs, and the Delaney RH40xx is a 4 inch by 4 inch residential hinge offered in 5/8 inch radius and square corner. Both match the DSB4R5N footprint and corner radius so the existing mortise is reused; the DSB4R5N adds the non-removable pin and a solid brass body.

The DSB4R5N is sold as a pair, two hinges. A standard 6'8" door normally takes three hinges, so plan on ordering two pairs per door and keeping the spare, or order in quantity if you're doing a run of openings. Taller or heavier slabs take four.

Wood screws, #12 x 1-1/4 inch. There are no machine screws supplied, so these are set up for wood jambs and wood door edges rather than hollow metal frames. If you're hanging a heavy solid-core or exterior slab, many installers swap two of the jamb screws for a longer screw that reaches the framing stud behind the jamb.

Solid brass throughout, not plated steel, which is why they hold up on exterior openings and why they can be finished in decorative colors. Two finishes are offered: Oil Rubbed Bronze and Brushed Nickel. Brass leaves also mean you can match the hinges to solid brass levers and trim on the same door.

No handing to specify. It's a full mortise butt hinge with a removable-pin-style barrel that is symmetrical, so one pair works on a left or right hand door. Just note the NRP set screw is only accessible with the door closed, which is normal.

Not in the same mortise. The Schlage Residential S3P1010 is a 3-1/2 inch by 3-1/2 inch square corner plain bearing mortise hinge sold in packs of three, while the DSB4R5N is 4 inch by 4 inch with 5/8 inch radius corners and sold as a pair. Swapping the smaller hinge into a 4 inch pocket leaves a visible gap and shifts the screw pattern. In 3-1/2 inch openings with radius corners, the Delaney RH35xx is a 3-1/2 inch by 3-1/2 inch residential hinge with 5/8 inch radius corners.

No. Those are not plain substitutes. The Command Access ETH-CB70 is an energy transfer hinge that carries power through the door, and the ETM-CB70 adds door position sensing. The DSB4R5N is a mechanical solid brass full mortise hinge with a non-removable pin and no wiring provision, so it cannot power an electrified lock or report door status.

Only if the frame prep differs. The Hager 1129 is a half mortise plain bearing hinge in 4-1/2 inch standard weight steel, so one leaf surface-applies to the frame. The DSB4R5N is full mortise at 4 inch by 4 inch, with both leaves let into the door and jamb. They share the plain bearing type but not the prep or the leaf size.

No. The DSB4R5N is a plain bearing full mortise hinge with no spring mechanism. For self-closing action, the Stanley Security 2060R in 4-1/2 inch by 4-1/2 inch is a full mortise spring hinge with square corners on a ferrous steel base. Note it is square corner and 4-1/2 inch, so the mortise prep differs from the 4 inch by 4 inch 5/8 inch radius pocket the DSB4R5N fits.

The DSB4R5N covers the common security concern on an outswing door by using a non-removable pin, but it is a residential duty brass hinge. For detention or extreme abuse conditions, the BEST BB855 is a heavy-duty steel double weight concealed ball bearing prison hinge, and the Hager 990 STEEL is a 3 inch by 4 inch full surface prison hinge with a welded tip. Those are surface or heavy steel preps, not a 4 inch by 4 inch full mortise brass swap.

The DSB4R5N is solid brass at 4 inch by 4 inch. In steel at the same nominal size, the Delaney CH401X is a 4 inch by 4 inch commercial ball bearing hinge with square corners, and the Orca Hardware COM4014 is a 4 inch by 4 inch plain bearing commercial hinge with 1/4 inch radius corners. Check the corner style against the existing mortise, since the DSB4R5N is cut for 5/8 inch radius.

.129 inch per leaf. That matters when you're mixing hinges on one door: pairing a .129 leaf with a thinner or thicker hinge on the same jamb changes how the door sits and can bind the edge or throw off the latch alignment. Keep all hinges on an opening to the same leaf gauge.

Yes. The DSB4 Series solid brass hinges can be fitted with decorative finials in place of the plain tips, which is how you dress up an exposed hinge barrel on a visible interior opening. The finials are ordered separately from the hinges.
