Emtek Modern Classic Brass Leverset - Poseidon Lever, Privacy Set

Depends which spec you're working to. The Poseidon privacy set is described as fitting any door from 1-3/8 inches to 2-1/4 inches thick with a standard 2-1/8 inch bore prep, while the spec table for the set gives a door thickness of 1-3/8 inches to 1-3/4 inches. Anything in the 1-3/8 to 1-3/4 inch band is covered either way, and 1-3/4 inches is the standard commercial door thickness. There is also a Door Thickness field on the order so you can state the actual thickness of your door and have the set supplied for it.

Both. Backset is a required choice at order time, 2-3/8 inches or 2-3/4 inches, and the latch is adjustable between the two. The standard latch supplied is set up for 2-3/8 inches, so if your existing bore is drilled to 2-3/4 inches you have to specify that. Cross bore is 2-1/8 inches, which is the standard residential door prep.

Handing matters here. The Poseidon lever is ordered as Left Hand (LH) or Right Hand (RH). Stand on the outside of the door, the side you'd approach from in the hallway: if the hinges are on your left it's a left hand door, hinges on the right it's a right hand door. Get it wrong and the lever points the wrong way. Note this is different from the non-handed commercial levers like the Falcon B101, which is a non-handed design you can hang either way.

Privacy, or bed and bath function. The Poseidon set locks with a thumbturn from the inside and has no key cylinder, so it's for bedrooms and bathrooms, not exterior or lockable storage doors. If you need a key on the door, this is the wrong function. Emtek's brass leversets also come in passage and dummy variations, and among other brands the Baldwin Estate 5103 is offered in privacy, passage and half dummy versions of the same lever if you're standardizing a run of doors on one look.

Six rosettes: Disk, Modern, Modern Rectangular, Neos, Square and Urban Modern, and the Poseidon lever can be ordered on any brass rosette. Prep is the standard 2-1/8 inch bore for these. The one to watch is the STRETTO rosette, which needs a 1-1/4 inch diameter bore hole and a 2-hole door preparation for the thumbturn privacy, so it is not a drop-in on a door already bored 2-1/8 inches.

No. The Poseidon set is a residential tubular lockset, brass trim on a bored prep, and it is not the part for a school, office corridor or anything spec'd to an ANSI grade. For a commercial privacy or bath door, look at a graded cylindrical lock instead: the Hager 2540 Grade 2 with the Withnell lever, or the Arrow MK02-TA Grade 2 privacy lock with a Tudor knob if a knob is acceptable. Poseidon is the right choice for apartments, condos, single family and hospitality guest rooms where the look is doing the work.

On prep, yes in most cases. The Kwikset 300BRNL Breton privacy lever covers 1-3/8 to 1-3/4 inch doors, the same band the Poseidon spec table gives, and both are standard bored privacy sets. What changes is the trim: Poseidon is solid brass in seven finishes on your choice of six rosettes, where the builder-grade set is a Grade 3 residential lock. Confirm your existing backset first, since Poseidon ships set for 2-3/8 inches unless you specify 2-3/4.

The Baldwin Estate 5103 Privacy Lever with 5048 Rose is the nearest decorative-line match. Both are privacy/bed/bath lever sets built for interior bedroom and bathroom doors, so the opening prep and the thumbturn-inside, emergency-release-outside behavior are the same. The Poseidon differs in that it is a solid brass set offered in Flat Black (US19), Oil Rubbed Bronze (US10B), Polished Chrome (US26), Polished Nickel - Lifetime (US14), Satin Brass (US4), Satin Nickel (US15), and Unlacquered Brass (US3NL), and the lever can be paired with a Disk, Modern, Modern Rectangular, Neos, Square, or Urban Modern rosette. The Baldwin 5103 comes on its 5048 rose.

Hall and closet doors take a passage set, which latches but does not lock. In a decorative brass line the Baldwin Estate 5103 Passage Lever with 5048 Rose is the matching-family passage version of the same lever. For a builder-grade run, the Kwikset 200BRNL RDT Breton passage lever is Grade 3 and covers 1-3/8 inch to 1-3/4 inch doors, and the Callan Asheville CLN-AH5011 is a Grade 3 passage leverset in satin nickel. The Poseidon itself is a privacy/bed/bath set with a thumbturn and is not the part for a closet.

The Poseidon latch is specified for doors 1-3/8 inch to 1-3/4 inch. For a 2 inch door, the Deltana 6201 Manchester, 6411 Morant and 6431 Linstead lever sets all cover 1-3/8 inch to 2 inch, and the Dexter C1000 Series asylum lock covers 1-3/8 inch to 2 inch as well. The Deltana sets are entry function and the Dexter is a Grade 1 asylum lock, so confirm the function matches the room before ordering.

No. The Poseidon is a non-keyed privacy set, so it takes a thumbturn rather than a cylinder. For a keyed entry or office opening in a decorative brass line, the Deltana 5851 Claremont and 6201 Manchester are entry-function lever sets. For graded keyed options, the Cal-Royal AG00 is a Grade 2 entrance lever with a 6-pin Schlage C keyway keyed different on a 2-3/8 inch backset, the Hager 2525 is a Grade 2 commercial entry lock, and the Dexter C1000 entry/office is Grade 1.

It ships as a complete set: both levers, the rosettes you select, the latch and the strike plate. The latch faceplate is available round corner or square corner so it drops into the mortise already cut in your door edge. If you pick the CF (concealed fastener) mechanism, a 28 degree rotation latch is included with it.

CF stands for concealed fastener: the rosettes mount with no screws showing on the face. It's a finish-quality decision, not a function one. Three choices are offered on the Poseidon privacy set: CF mechanism, the 28 degree rotation latch (Latch28) on its own, or no thanks for the standard exposed-screw mounting. Selecting CF brings the 28 degree latch with it. If the door is in a visible living space and you're spending on solid brass trim, the clean rosette is the reason people take it.

Seven finishes: Flat Black (US19), Oil Rubbed Bronze (US10B), Polished Chrome (US26), Polished Nickel Lifetime (US14), Satin Brass (US4), Satin Nickel (US15) and Unlacquered Brass (US3NL). Split finish is offered as an optional entry on the order, so you can run one finish on the corridor side and another inside the room, which is what people do when a bathroom or closet faces a hall done in a different metal. Unlacquered brass will patina with handling; the lacquered and plated finishes will not.

Yes. Poseidon is a design within Emtek's brass leverset range and the same lever is offered in other functions, so bedrooms and baths take the privacy set while halls and closets take passage. Order every door in one finish and one rosette style and the run reads as a set. If you want the same approach from another brand, the Baldwin Estate 5103 with the 5048 rose is offered in passage, privacy and both left and right hand half dummies, which covers closet and french door leaves too.

Functionally yes, aesthetically no. The Kwikset 300BRNL RDT Breton is a Grade 3 privacy lever set fitting 1-3/8 inch to 1-3/4 inch doors, which is the same door range the Poseidon covers, and both are non-keyed privacy sets. The difference is construction and trim: the Poseidon is solid brass in a contemporary style, offered with a choice of six rosette shapes and an optional concealed fastener mechanism so the rosettes carry no exposed screws. The Breton comes as a fixed round-trim set.

That is a dummy trim, a lever fixed to the door with no latch or turning mechanism. The Baldwin Estate 5103 is offered as a half dummy in left hand (BAL-5103-LDM) and right hand (BAL-5103-RDM) with the 5048 rose, which is the decorative-line answer. On the commercial side the BEST 9K Series 1DT is a Grade 1 heavy duty single dummy trim and the BEST 7KC Series 1DT is the Grade 2 medium duty equivalent. The Poseidon is a latching privacy set and will not serve as dummy trim.

The Bravura Miramar BV940-106 is a Grade 2 passage leverset with round trim supplied in US4 satin brass, and the Cal-Royal AUS00 is a Grade 3 entrance/office lever with a solid brass forged body covering 1-3/8 inch to 1-3/4 inch doors. Note the function difference: neither is a privacy set the way the Poseidon is, so for a bedroom or bath door the Poseidon or another privacy-function lever is the correct part.

They solve different problems. The Poseidon privacy set locks from inside with a thumbturn for a bedroom or bath. The Lockey 2835 is a mechanical pushbutton keyless lever with passage function and ADA compliance for 1-3/16 inch to 2 inch doors, and the Lockey 2835DC is the double combination version of the same. The Lockey 1150 and 1150S are heavy duty mechanical keypad lever sets for 1-1/8 inch to 2 inch doors, the 1150S with adjustable backset. Use a Lockey where you want code-controlled access from the outside, the Poseidon where you want simple occupant privacy.

Yes, the Poseidon privacy set is specified as left hand or right hand, so the door swing has to be determined before ordering. Baldwin handles this the same way on its half dummies, with separate left hand (BAL-5103-LDM) and right hand (BAL-5103-RDM) Estate 5103 part numbers. If handing is a problem on a job where swings vary, the Falcon B101 is a Grade 2 passage lever with a non-handed design and the Falcon K101 uses non-handed levers as well, though both are passage rather than privacy.

The Poseidon ships with an adjustable latch for 2-3/8 inch or 2-3/4 inch backset, selected at order. Among the graded peers, the Cal-Royal AG03 classroom lever is built on a 2-3/4 inch backset while the Cal-Royal AG00 entrance lever is a 2-3/8 inch backset, and the Lockey 1150S keypad lever set has an adjustable backset. Measure from the door edge to the center of the bore before choosing.

Brass throughout, both material and substrate, in Emtek's Brass collection. That matters on a lever more than on most hardware: the handle takes the load every time someone opens the door, and brass holds up to it where zinc castings work loose. The finish list runs from plated options like polished chrome and satin nickel over that brass core to unlacquered brass where the metal is left bare.

No, it's a mechanical privacy set with a thumbturn, no electronics and no code. If you need keyless entry on a lever, that's a different product: the Lockey 2835 mechanical pushbutton keyless lever handles 1-3/16 to 2 inch doors, the Lockey 1150 covers 1-1/8 to 2 inches, and the Delaney LP250 is an electronic keypad leverlock. None of those are privacy function.
