Deltana CSB45N 4-1/2" x 4-1/2" Square Hinges (Pair), Non-Removeable Pin (NRP)

The CSB45N is built with a non-removable pin, so once the door is closed a set screw in the barrel keeps the pin from being driven out. That matters on any out-swing opening where the barrel sits on the outside of the door, which is the usual reason a spec calls for NRP. It will not stop the door being pried, but it removes the easiest attack: pull the pin, lift the door off.

It fits a 4-1/2 inch by 4-1/2 inch square corner mortise. Square corner means the leaf corners are cut sharp, not rounded, so it drops straight into a chiselled or router-with-square-corner-chisel prep. If your existing hinges are the same size but have a 1/4 inch or 5/8 inch radius corner, the CSB45N leaf will not seat in the rounded pocket without corner work on the jamb and door.

Plain bearing is what the CSB45N uses, and that is the lighter-cycle choice. For a door under a closer, or any high traffic opening, a ball bearing or concealed bearing hinge holds up better. Deltana's plain bearing brass suits moderate-use commercial and residential doors. If the opening is busy, the Orca Hardware 3535 Series is a 4-1/2 by 4-1/2 square corner ball bearing commercial hinge in the same size, and the Hager BB1168 is a heavy duty ball bearing full mortise hinge that is also available non-removable pin.

No. The CSB45N is a plain mechanical brass hinge with no wire path. Power transfer needs a dedicated electrified hinge, such as the Command Access ETH-CB70 energy transfer hinge on a standard weight steel base, the heavier ETH-BB68, or the BEST CECB179-12C full mortise concealed bearing electrified hinge with a 12-wire quick connect. If you also need door position monitoring, the Command Access ETM-CB70 adds a position sensor.

The Deltana CSB45N is a 4-1/2 inch by 4-1/2 inch square corner full mortise hinge in solid brass with a non-removable pin. If you want the same NRP security feature on a steel hinge, the Hager BB1168 is a full mortise ball bearing heavy duty hinge furnished with a non-removable pin. The CSB45N uses a plain bearing, so the Hager moves you to ball bearing knuckles as well as to a steel base.

The Orca Hardware 3535 Series is a 4-1/2 inch by 4-1/2 inch square corner ball bearing commercial hinge rated medium duty, and the Stanley Security FBB191 is a 5-knuckle full mortise standard weight hinge in the same 4.5 by 4.5 size. Both match the CSB45N footprint and square corner prep, so they drop into the same mortise; neither is described with the non-removable pin the CSB45N carries, so use them on interior or non-outswing openings where pin security is not a concern.

The CSB45N is a 4-1/2 inch by 4-1/2 inch hinge and will not fit a 3-1/2 inch mortise without recutting the jamb and door. For a 3-1/2 inch square corner plain bearing hinge, the Emtek 91013 comes as a pair in plated steel, the Emtek 92013 is the heavy duty plain bearing version in the same size and corner style, and the Schlage Residential S3P1010 is a 3.5 by 3.5 square corner plain bearing mortise hinge sold in packs of three for a three-hinge opening.

The CSB45N is a mechanical brass hinge with no wiring provision. For power transfer through the hinge, the Command Access ETH-CB70 is a 3-knuckle standard weight steel energy transfer hinge rated medium duty, and the ETH-BB68 is the 5-knuckle heavy duty version. If you also need door position monitoring, the Command Access ETM-CB70 senses door position on a 3-knuckle steel base. The Stanley CECB1900R54L is a 4-1/2 by 4-1/2 square corner concealed conductor hinge with 4 wires, matching the CSB45N size and corner prep.

Brass is the base material and substrate on the CSB45N, and it is the usual pick for exterior and coastal openings because it does not rust the way a plated steel hinge does when the plating wears at the knuckle. The trade-off is that brass is softer than steel, so for heavy doors and high cycle counts a steel base hinge such as the Stanley FBB191 in the same 4.5 by 4.5 size is the sturdier route.

PVD Polished Brass is the finish. PVD is a deposited coating rather than a lacquer, so it holds its colour in sun and weather far longer than standard lacquered polished brass. It pairs with other PVD polished brass trim; next to a lacquered US3 lever it will look slightly different once the lacquered piece starts to age.

It is classed commercial, full mortise, in the 4-1/2 inch size that commercial 1-3/4 inch doors are prepped for. Residential interior doors are usually 3-1/2 inch, which is why hinges like the Emtek 91013 and the Schlage S3P1010 come in that size. If you are matching an existing commercial opening, the 4-1/2 square corner prep is the one to confirm.

No. A full mortise butt hinge like the CSB45N is symmetrical and works on either hand; you just flip it. Handing only becomes an order decision on hinges with built-in electrical or monitoring, such as the Stanley CECB1900R54L, which is specified left-handed.

The Deltana CSB45N is a standard plain bearing hinge with no spring. The Stanley Security 2060R is a full mortise square corner spring hinge in 4.5 inch by 4.5 inch on a ferrous steel base, rated heavy duty, so it matches the CSB45N size and corner prep while providing the closing force.

Both are 4-1/2 inch by 4-1/2 inch full mortise hinges, but they are built differently. The McKinney SQ3331 is a square barrel 2-knuckle decorative hinge rated standard duty, while the CSB45N is a square corner solid brass hinge with a plain bearing and a non-removable pin. If the pin security is what you are buying, the SQ3331 is not the match; if you want the square barrel look on an interior opening, it is a different visual treatment in the same size.

No. The Hager 1129 is a half mortise plain bearing commercial hinge, meaning one leaf mortises into the door and the other surface-applies to the frame. The CSB45N is a full mortise hinge that mortises into both the door and the jamb. They share the 4-1/2 inch size and plain bearing construction but require different door and frame prep, so they are not interchangeable on an existing opening.

The CSB45N has square corners and will leave gaps in a mortise cut with a radius router. For 5/8 inch radius corners, the Delaney RH45 series is a 4 inch by 4 inch exterior residential hinge sold in pairs, and the RH35 series is the 3-1/2 inch interior version. If your prep is 1/4 inch radius instead, the Orca 4014 Series is a 4 inch by 4 inch quarter-radius plain bearing commercial hinge.

Plain bearing hinges like the CSB45N suit openings without a closer or heavy leaf. For doors with closers or continuous cycling, the Ives 3CB1HW is a steel heavy weight concealed bearing full mortise hinge with 3 knuckles, and the Ives 3CB1 is the medium duty concealed bearing version of the same full mortise format. The Orca 3535 Series gives you ball bearings at medium duty in the same 4-1/2 inch square corner size as the CSB45N.

The CSB45N is a commercial-rated solid brass plain bearing hinge with a non-removable pin, which addresses pin removal from the secure side of an outswing door. For detention-level openings, the BEST BB855 is a heavy-duty steel double weight concealed ball bearing prison hinge from the detention hardware line, and the Hager 990 STEEL is a 3 inch by 4 inch full surface prison hinge with a welded tip rated heavy duty. Those use different mounting and prep than the CSB45N full mortise format.

The Orca Hardware 4040 Series is a 4 inch by 4 inch square corner plain bearing commercial hinge at medium duty, which keeps the same plain bearing and square corner character as the CSB45N in a smaller leaf. The Delaney CH401X is a 4 inch by 4 inch commercial ball bearing hinge with square corners if you want bearings at that size.

The CSB45N is solid brass, which is non-ferrous and suits coastal or damp openings where steel corrodes. The McKinney T2314 is a non-ferrous 5-knuckle standard weight hinge rated medium duty if you want that corrosion behavior from a different maker, though it is not described with the non-removable pin the CSB45N carries.
