Emtek Classic Brass Knobsets with Designer Rosettes - Norwich Knob, Dummy (Pair)

No door prep at all. The Norwich dummy knobset is surface mounted, so it screws to the face of the door with no 2-1/8 inch cross bore and no latch bore. That makes it the part to use on a closet or pantry slab that was never drilled, or on a false door leaf where you only want something to pull on.

It just sits there. A dummy is a non-keyed, non-latching trim: no latchbolt, no turn, no cylinder. The knob is fixed and serves as a pull. If you need the door to stay shut you want a passage or privacy set instead, something like the Cal-Royal BA40 range's live functions or a Dexter C2000 passage knob, and those need a bored prep in the door.

Two. The Norwich dummy ships as a pair, a complete set with a knob and rosette for each face of the door. Buy it for double doors or for a single door where you want a knob on both sides. If you only need one face, a single dummy trim like the Schlage A170 or the Omnia 434/0 is the one-sided equivalent.

The Norwich dummy knobset is a residential brass set. For commercial duty, the Schlage A170 single dummy trim is a Grade 2 heavy duty cylindrical non-keyed knob lock covering 1-3/8 inch to 1-7/8 inch doors, and the BEST 6K series single dummy trim is a Grade 2 medium duty non-keyed cylindrical knob. Both are dummy function like the Norwich, so the door still has no latch, but they carry a commercial ANSI grade the residential brass set does not.

A dummy knob has no latch at all, so if the door needs to stay closed you want a passage knobset. The Omnia 434/PA traditional egg-shaped knob latchset is solid brass with a 3 inch projection and passage function; the Baldwin Estate 5011 Colonial passage knob with 5058 rose is also passage function. For a commercial opening, the Corbin Russwin CK4310 is a Grade 1 passage/closet cylindrical lock for 1-3/8 inch to 2 inch doors, and the Falcon W101 is a Grade 2 passage/closet knob lock with a 2-3/4 inch backset and a fire rating.

The Norwich dummy knobset is rated for 1-3/8 inch to 1-3/4 inch doors and mounts to the surface with no door prep. Among the knob sets that reach 2 inches, the Corbin Russwin CK4310 passage/closet lock and the Deltana 6171 Round knob entry both cover 1-3/8 inch to 2 inch doors, and the Falcon X101 Grade 1 passage knobset reaches 1-3/8 inch to 2-1/4 inch. Those are latching functions rather than dummy trim, so the door will latch where the Norwich would not.

The Norwich is a residential brass dummy set. Where the opening calls for a fire-rated cylindrical knob lock, the Falcon W101 Grade 2 passage/closet knob lock and the Falcon X101 Grade 1 heavy duty passage knobset with interchangeable core both carry a fire rating, the X101 covering 1-3/8 inch to 2-1/4 inch doors.

Rope, Lancaster, and Ribbon & Reed are the catalogued rosettes, and any other Emtek brass rosette can be ordered by naming it in the comments field on the order. Every rosette choice is offered in all seven finishes, so the backplate style and the finish are independent decisions.

Yes. There is a split finish option on the order where you specify the finish for each side. Useful when a bedroom or closet door faces a hall in one palette and a room in another. The seven finishes to choose from are Oil Rubbed Bronze US10B, Satin Nickel US15, Pewter US15A, Polished Chrome US26, Polished Brass Lifetime US3, Unlacquered Brass US3NL, and French Antique US7.

No, and the difference grows over time. Unlacquered Brass US3NL has no protective coating, so it darkens and patinas with handling. Polished Brass Lifetime US3 is coated to hold its shine. Pick one or the other across a project; mixing them on adjacent doors will look mismatched within months.

It is a residential product, solid brass, traditional styling. For a commercial opening that has to meet a duty spec, go to a graded cylindrical lock instead: the Schlage D10S passage is Grade 1 heavy duty, and the Corbin Russwin CK4310 is Grade 1 for passage and closet openings up to a 2 inch door.

That is exactly what the pair suits. Surface mounted with no prep, one knob per leaf, nothing that has to line up with a strike or a mortise. On an inactive leaf of a pair it gives you a matching pull without cutting the door.

Yes, within the Emtek brass program. The Norwich knob and its brass rosettes are the same design family used on Emtek's passage and privacy knobsets, so the closet dummies read the same as the functioning doors down the hall when you order the same knob design, rosette, and finish across all of them.

The Norwich knobset is a non-keyed dummy, so it provides no privacy latch of its own. For a bath or bedroom door, the Baldwin Estate 5077 Bethpage privacy knob with R027 rose and the Deltana 6112 St. Thomas privacy knob, which fits 1-3/8 inch to 2 inch doors, both give a traditional knob with privacy function. On a commercial job the Dexter C2000 Grade 2 privacy ball knob covers 1-3/8 inch to 1-3/4 inch doors.

The Cal-Royal BA40 dummy knob cylindrical lock in the Barrington BA series covers 1-3/8 inch to 1-3/4 inch doors, and the Bravura Biloxi round trim dummy knobset is a Grade 2 dummy. Both are plainer round-trim dummy knobs, where the Norwich is a brass knob in a traditional American Classic style with a choice of designer rosettes such as Rope, Lancaster, and Ribbon and Reed.

They share the dummy function but not the count or the build. The Schlage A170 is a single dummy trim, Grade 2 heavy duty, for one face of a door; the Norwich dummy is sold as a pair of brass knobs, which is what a double door or a set of French doors needs. If you are dressing both leaves with A170 trim you would order two.

A dummy knob does not accept a cylinder at all. For a keyed traditional knob, the Deltana 3381 Egg knob entry and the Deltana 6901 Portland knob entry are entry function, the 3381 fitting 1-3/8 inch to 2 inch doors and the 6901 fitting 1-3/8 inch to 1-3/4 inch doors. On the commercial side, the Corbin Russwin CK4851 is an entrance/office cylindrical lock with a conventional cylinder for 1-3/8 inch to 2 inch doors.

The Norwich brass knobset is offered in dummy function and is non-keyed, so a mixed-function floor needs a second source for the latching and keyed openings. The Dexter C2000 series runs Grade 2 passage, privacy, entry/office and classroom ball knobs all on 1-3/8 inch to 1-3/4 inch doors, and the Pamex FTF Baron Grade 3 knob lockset comes in entrance/office, privacy and passage on the same thickness range. Either lets one knob design carry every function in the building.

Not the same part. A passage knob such as the Kwikset 200P Polo, supplied with a 6AL latch and RCS round corner strike, or the Baldwin Estate 5000 Baltimore knob with 5048 rose, which comes with a 2-3/8 inch backset and full lip strike, both bore through the door and throw a latch into a strike. The Norwich dummy pair is surface mount with no door prep and no latch, which is what an inactive French-door leaf or a false-front door wants.
