Emtek Crystal Knobsets - Lowell Knob, Dummy (Pair)

It's dummy trim only. The Lowell knob set is a non-keyed dummy function, so there is no latch, no spindle rotation to retract anything, and nothing to lock. You use it as a fixed pull on a door that doesn't need to latch, like a closet door held by a ball catch or roller catch, or on the inactive leaf of a French door pair. If you need the knob to turn and retract a latch, order a passage function instead.

No door prep is needed. The Lowell dummy is surface mount, 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 easy choice on a slab that's already finished or on a glass-panel French door stile you don't want to drill through for a lock.

Two. The Lowell dummy is sold as a pair, one knob and rosette for each face of the door, supplied as a complete set. That's what you want on a French door or a double-sided closet door where both faces are visible. If only one side needs a pull, a single dummy such as the Schlage A170 or the Omnia 434/0 covers it.

The Lowell crystal knob in dummy function has no latch and is surface mounted with no door prep, so it only serves as a pull. For a door that must latch closed, passage knobsets include the Omnia 434/PA latchset in solid brass with a 3 inch projection, the Baldwin Estate 5011 Colonial passage knob with 5058 rose, and the Pamex FTF Baron in passage function, Grade 3. Those require a bored door prep the dummy does not.

They are different functions. The Lowell crystal knob is non-keyed dummy trim with no latch, so it will not hold a door closed. A closet door that needs a latch takes a passage set such as the Dexter C2000 Grade 2 passage ball knob for 1-3/8 to 1-3/4 inch doors or the Corbin Russwin CK4410 Grade 2 passage/closet lock in the same thickness range. A privacy set like the Pamex FTF Grade 3 privacy knob adds a bed and bath lock function no dummy provides.

Yes, the rosette is its own ordering choice. Six Sandcast Bronze rosette styles are offered, numbered #1 through #6, and any of them can be paired with the Lowell crystal knob. Choose the rosette to match the other Emtek trim in the room, then the finish.

Three Sandcast Bronze finishes: Flat Black Bronze (FB), Medium Bronze (MB), and Tumbled White Bronze (TWB). Each is available with any of the six rosette styles. If you want the knob and the rosette in different finishes, there's a split finish note field on the order to specify that.

The Lowell is a glass knob from Emtek's Glass and Porcelain collection on brass base metal, and it's classified residential. It's decorative trim for homes and hospitality-style interiors, not a graded commercial lockset. For a corridor or a high-traffic institutional opening, go to a graded cylindrical unit such as the Grade 1 Schlage D10S passage or the Grade 2 BEST 6K single dummy trim.

The Lowell dummy has no latch, so pair it with Emtek's passage and privacy versions of the same Lowell crystal knob to keep the look consistent across the room. Those are separate bored functions requiring a normal 2-1/8 inch cross bore, while the dummy needs no prep at all. Keep the same rosette number and finish code across all of them.

Not on its own. There is no privacy bolt and no keyed cylinder in a dummy, so it won't secure a bath or bedroom. For that opening use a privacy function knob, for example the Pamex FTF Baron privacy, the Cal-Royal BER20, or the Deltana 6112 St. Thomas privacy knob.

The Lowell crystal knob is a residential glass and porcelain collection design in the American Classic theme. For a plainer dummy on commercial doors, the Schlage A170 A Series single dummy trim is Grade 2 heavy duty and fits doors 1-3/8 to 1-7/8 inch, the BEST 6K-1DT is Grade 2 medium duty, and the Cal-Royal BA40 Barrington dummy knob fits 1-3/8 to 1-3/4 inch doors. The Emtek set covers 1-3/8 to 1-3/4 inch doors.

The Lowell crystal dummy pair is rated for doors 1-3/8 to 1-3/4 inch. For thicker doors, the Corbin Russwin CK4310 Grade 1 passage/closet lock and the Deltana 6171 Round Knob entry both cover 1-3/8 to 2 inch, and the Falcon X101 Grade 1 heavy duty passage knobset covers 1-3/8 to 2-1/4 inch. Those are latching functions rather than dummy trim.

No. It's fully mechanical trim, non-electronic and non-keyed, with nothing to wire or power. Nothing about it interfaces with an access control system.
