Deltana CSB4540SN 4-1/2" x 4" Square Corner Hinges, 3-Knuckle, NRP(Pair)

The CSB4540SN measures 4-1/2 by 4 inches, and Deltana lists it as a wide throw square corner hinge. The leaf height is 4-1/2 inches and the open width is 4 inches, so it is not the usual 4-1/2 x 4-1/2 square hinge. Wide throw leaves are what you use when trim or a thick jamb means the door has to clear the casing when it swings back.

Yes, NRP is built in. The pin cannot be driven out from the knuckle, so someone outside an outswing door cannot pull the pin and lift the door out of the frame. That is the reason to specify this version over a standard pin hinge on any door that swings out.

The Deltana CSB4540SN is a solid brass plain bearing hinge rated residential, so for heavier cycle counts look at a bearing hinge built for commercial service. The Orca Hardware 3535 Series is a 4-1/2 inch by 4-1/2 inch square corner ball bearing commercial hinge at a medium duty level, and the Hager BB1168 is a full mortise ball bearing heavy duty hinge. Both trade the brass decorative look for a bearing-equipped steel commercial build.

The CSB4540SN measures 4-1/2 inches by 4 inches, so it will not drop into a 3-1/2 inch mortise. For that prep, the Schlage Residential S3P1010 is a 3.5 by 3.5 inch square corner plain bearing mortise hinge in a pack of three, and the Emtek 92013 is a 3-1/2 by 3-1/2 inch square corner plain bearing pair in plated steel.

The Deltana CSB4540SN provides the NRP feature on a solid brass hinge. The Hager BB1168 is a non-removable pin full mortise ball bearing heavy duty hinge with a steel build, which is the usual choice when the outswing door is exterior and the finish is less of a concern than the duty rating.

No. The CSB4540SN has square corners, which need a square-cut mortise. For a 1/4 inch radius pocket, the Orca Hardware 4014 Series is a 4 by 4 inch quarter radius corner plain bearing commercial hinge, and the Delaney RH45xx exterior residential hinge pair is a 4 by 4 inch with a 5/8 inch radius for that corner profile.

The CSB4540SN is a mechanical full mortise brass hinge with no wiring provision. For power transfer, use an electrified hinge: the Command Access ETH-CB70 is a 3-knuckle standard weight energy transfer hinge on a steel base, the BEST CECB179-12C is a full mortise concealed bearing electrified hinge with a 12-wire quick connect, and the Command Access ETM-CB70 adds door position sensing.

It is sold as a pair. A standard 1-3/4 inch exterior door normally takes three hinges, so figure two pairs per opening if you want three on the door plus a spare leaf, or order accordingly for a two-hinge interior door.

Deltana specifies #12 x 1/2 inch machine screws with this hinge. Machine screws thread into a prepped metal frame or tapped leaf; if you are hanging into a wood jamb, plan on longer wood screws into solid framing so the door's weight is not carried by a 1/2 inch fastener in casing.

Solid brass, with a leaf thickness of .134 inch. Brass is the reason it gets used on exterior and higher-end residential openings where a plated steel hinge would eventually show corrosion at the knuckle.

On interior doors where an NRP is unnecessary, the Emtek 91013 is a residential plain bearing hinge pair with square corners in plated steel, and the Ives 1010RP is a steel plain bearing residential hinge with square corners sold as a set of three. Both share the plain bearing action of the CSB4540SN without the security pin or the solid brass body.

No. The CSB4540SN is a 3-knuckle plain bearing brass hinge. A concealed bearing hinge hides the bearing inside the knuckle for a smooth barrel: the Ives 3CB1 is a 3-knuckle concealed bearing full mortise hinge at medium duty, and the Ives 3CB1HW is the heavy weight concealed bearing version. Those are steel commercial hinges rather than decorative brass.

The CSB4540SN is a standard plain bearing hinge and will not return the door. The Stanley Security 2060R is a full mortise spring hinge with square corners at 4.5 by 4.5 inches on a ferrous steel base, which matches the square corner prep while providing self-closing action.

The CSB4540SN is a 4-1/2 inch solid brass hinge that can be dressed with decorative finials. If the look wanted is a square barrel instead, the McKinney SQ3331 is a 2-knuckle decorative hinge at 4-1/2 by 4-1/2 inches, standard duty. Note it is 4-1/2 square, so confirm the frame leaf width before swapping.

The CSB4540SN offers a non-removable pin on a residential brass hinge, which deters pin pulling on an outswing door but is not a detention product. Purpose-built options include the BEST BB855 heavy-duty steel double weight concealed ball bearing prison hinge and the Hager 990 STEEL full surface prison hinge, 3 by 4 inch with a welded tip, heavy duty.

No. The CSB4540SN is a full mortise hinge, meaning both leaves mortise into the door and frame. For a channel iron or non-mortised frame, the Hager 1129 is a half mortise plain bearing commercial hinge, 4-1/2 inch standard weight steel, and the Hager 990 STEEL is a full surface application.

PVD Polished Brass is the finish offered on this model. Deltana solid brass hinges also accept decorative finials in place of the plain tips, which is how you match a hinge to more ornate trim on the rest of the openings.

The CSB4540SN is a 3-knuckle brass hinge at .134 inch leaf thickness with a non-removable pin. A 5-knuckle standard weight hinge such as the Stanley FBB191 at 4.5 by 4.5 inches or the McKinney MPB79 MacPro distributes load across more knuckles and is specified on commercial steel frames; neither carries the solid brass body of the Deltana.

The CSB4540SN ships as a pair in solid brass. For volume interior work, the Delaney RH35xx is a 3-1/2 by 3-1/2 inch bulk steel residential interior hinge pair with a 5/8 inch radius, and the Delaney RH45xx is the 4 by 4 inch bulk exterior version. Match the corner profile to the existing frame prep before standardizing.
