Emtek 8100.LW.US15 – Frequently Asked Questions

1) Do I need to specify a backset when ordering the Emtek Lowell passage knob?
Yes, backset is a required selection: 2-3/8 inch or 2-3/4 inch. The 2-3/8 inch is what ships as standard, and 2-3/4 inch is the other common commercial bore. Measure from the door edge to the center of the bore hole before you order. Those are the two usual backsets found in residential and light commercial doors.
2) Is the Emtek Lowell crystal knob suitable for a commercial building or apartment corridor?
It is built as residential hardware, solid brass with a glass knob, and carries no ANSI grade. For an apartment corridor, office, or any door taking commercial traffic, look at a graded cylindrical passage lock instead: the Schlage D10S is Grade 1 heavy duty, the Corbin Russwin CK4310 is Grade 1 and covers doors 1-3/8 to 2 inches thick, and the Arrow MK01 is a Grade 2 passage knob for 1-3/8 to 1-3/4 inch doors.
3) I have a thick 2 inch door. Will the Emtek Lowell passage set still work?
Yes, up to 2-1/4 inches. That is a wider range than most residential knobsets cover, so it suits older or built-up doors. If you are cross-shopping, the Kwikset 400P-CP and the Dexter C2000 passage knob both stop at 1-3/4 inches, while the Falcon X101 covers 1-3/8 to 2-1/4 inches. Enter your actual door thickness in the Door Thickness field when you order.
4) My door is thicker than 1-3/4 inch. Which passage knob covers it if the Emtek Lowell does not?
The Emtek Lowell passage set lists a door thickness of 1-3/8 inch to 1-3/4 inch. For thicker doors, the Corbin Russwin CK4310 Grade 1 passage and closet cylindrical lock covers 1-3/8 inch to 2 inch, the Falcon X101 Grade 1 passage knobset covers 1-3/8 inch to 2-1/4 inch, and the Lockey 3830 mechanical keyless combination knob lock with auto-locking passage function covers 1-3/16 inch to 2 inch.
5) What looks like a substitute for the Emtek Lowell passage knob but will not latch the door?
Dummy trim looks the same on the door face but does not turn or retract a latch. The Omnia 434/0 egg-shaped knob and the Omnia 458/0 knob latchset with a 2-3/8 inch backset are both single dummy, the Schlage A170 is Grade 2 single dummy trim for doors 1-3/8 inch to 1-7/8 inch, and the BEST 6K single dummy trim and Bravura Biloxi are Grade 2 dummy. The Emtek Lowell is a complete passage set that includes the latch and strike plate.
6) What is a straight equivalent to the Emtek Lowell passage knob if I need the same hall and closet function in a plainer knob?
The Lowell knob is a passage set with a non-keyed passage function, so any non-keyed passage cylindrical knob covers the same opening. The Bravura Albany with round trim is a Grade 2 passage knobset, and the Bravura Lynchburg with round trim is the same Grade 2 passage function in a different knob shape. The Emtek Lowell is a brass set in the Glass and Porcelain collection, so the visual result differs even though the door function matches.
7) The Emtek Lowell knob is residential. What passage knob should I use on a commercial corridor door instead?
The Lowell knob is classified for residential use. For a commercial passage opening, the Schlage D10S is a Grade 1 heavy duty cylindrical passage knob lock with an Orbit knob, and the Falcon X101 is a Grade 1 heavy duty cylindrical passage knobset that is fire rated and takes an interchangeable core. The Corbin Russwin CK4310 is a Grade 1 passage and closet cylindrical lock with a Global knob covering doors 1-3/8 inch to 2 inch thick.
8) The door is a bedroom or bathroom. What do I order instead of the Emtek Lowell passage knob?
The Lowell passage set is non-keyed with a passage function, so it has no privacy lock. For a bed or bath door, the Baldwin Estate 5000 Baltimore knob with 5148 rose is a privacy lock with a 2-3/8 inch backset and full lip strike, the Baldwin Estate 5077 Bethpage is a privacy knob with an R027 rose, and the Deltana 6112 St. Thomas knob is a privacy knob covering doors 1-3/8 inch to 2 inch thick.
9) The opening needs a key. What takes the place of the Emtek Lowell passage knob on an entry door?
The Lowell knob is a non-keyed passage set. For a keyed entry, the Deltana 6901 Portland knob is an entry knob for doors 1-3/8 inch to 1-3/4 inch thick, the Deltana 3381 Egg knob is an entry knob covering 1-3/8 inch to 2 inch, and the Kwikset 400P-CP Polo is a Grade 3 keyed entry knob with a round corner adjustable latch and round corner strike for doors 1-3/8 inch to 1-3/4 inch.
10) What comes in the box with the Emtek Lowell crystal knob passage set?
It is a complete set: both knobs, the rosettes you select, the latch, and the strike plate. Nothing else has to be ordered to hang it on a properly bored door. The latch faceplate is available round corner or square corner, so match it to the mortise already cut in the door edge.
11) What is the difference between the 28 degree latch and the CF mechanism on Emtek knobsets?
Three latch choices. The standard latch is the conventional tubular latch. The 28 Degree Rotation Latch reduces how far the knob has to turn to retract the bolt. The CF Mechanism gives you rosettes with no exposed screws for a clean face, and the 28 degree latch is included with it. If the look of the rosette matters on a visible interior door, the CF option is the one to pick.
12) Can I match the Emtek Lowell knob to other hardware finishes already in the house?
Ten finishes are offered: Flat Black (US19), French Antique (US7), Oil Rubbed Bronze (US10B), Pewter (US15A), Polished Brass Lifetime (US3), Polished Chrome (US26), Polished Nickel Lifetime (US14), Satin Brass (US4), Satin Nickel (US15), and Unlacquered Brass (US3NL). Split finish is also available as an order option if you want a different finish on each side of the door.
13) Can I use the Emtek Lowell knob as a dummy on a closet or French door that does not latch?
The Lowell passage set is a working latchset, not a dummy. For a non-latching door you want a single dummy trim: the Omnia 434/0 and 442/00 are solid brass traditional dummy knobs, the BEST 6K single dummy trim is a Grade 2 option, and the Schlage A170 dummy trim covers 1-3/8 to 1-7/8 inch doors.
14) I want a solid brass passage knob but a simpler traditional shape than the Emtek Lowell. What else is brass?
The Emtek Lowell passage set is brass. The Omnia 434/PA is a traditional egg-shaped knob latchset with solid brass construction and a 3 inch projection in a passage and closet function, and the Baldwin Estate 5011 Colonial passage knob with 5058 rose is another traditional passage knob. The Lowell knob itself is a glass style knob in the Glass and Porcelain collection rather than an all-metal knob.
15) Does an office door need something different from the Emtek Lowell passage knob?
An office door that has to be locked off needs an entrance or office function rather than passage. The Corbin Russwin CK4851 is an entrance and office cylindrical lock with a Global knob and conventional cylinder for doors 1-3/8 inch to 2 inch, the Dexter C2000 entry and office ball knob lock is Grade 2 and keyed for doors 1-3/8 inch to 1-3/4 inch, and the Pamex FTF Baron is a Grade 3 entrance and office knob lockset over the same range.
16) The Emtek Lowell needs a backset specified. Which passage knobs come with an adjustable or fixed backset already set?
The Emtek Lowell passage set uses a 2-3/8 inch or 2-3/4 inch backset, chosen at order. The Falcon W101 Grade 2 passage and closet knob lock is built with a 2-3/4 inch backset, the Baldwin Estate 5000 Baltimore passage knob with 5048 rose comes preconfigured with a 2-3/8 inch backset and full lip strike, and the Schlage Residential F500 Plymouth with Georgian knob ships as a combo pack with adjustable backsets and dual strikes for doors 1-3/8 inch to 1-3/4 inch.
17) I need the door to stay latched and locked from outside. What replaces an Emtek Lowell passage knob on a storeroom or closet door?
A passage set has no lock, so a storeroom function is a different part. The Sargent 6G04 is a Grade 2 standard duty storeroom and closet knob lock with a single cylinder, and the Sargent 8XG04 is a Grade 1 heavy duty storeroom and closet single cylinder knob lock with a 2-3/4 inch backset. The Imperial USA ED-BKL580 is knob trim in a storeroom function from the ED-500 series.
18) Which passage knob should I standardize on across a building if the Emtek Lowell is only for the front rooms?
For back of house and corridor doors alongside a decorative front, the Corbin Russwin CK4410 Grade 2 passage and closet lock and the Dexter C2000 Grade 2 passage ball knob both cover doors 1-3/8 inch to 1-3/4 inch, the same range the Emtek Lowell lists, so the door prep carries across. The Corbin Russwin CK4310 is the Grade 1 version of the same passage function if the traffic is heavier.
19) Can I use exit device knob trim in place of the Emtek Lowell passage knob?
No. Exit device trim mounts to a panic device, not to a standard bored door prep. The Sargent 28C-KNOB is exit device trim with a knob and rose in a classroom function for 1-3/4 inch doors, and the Sargent 78-2875 is an outside knob only in the B design. The Emtek Lowell is a complete tubular passage set that fits a 2-1/8 inch bore standard door prep and includes the latch and strike plate.
20) Which rosette shapes can I get with the Emtek Lowell knob?
Seven rosettes: #8, Oval, Quincy, Rectangular, Regular, Watford, and Wilshire. Any brass rosette in the range can be ordered with the Lowell crystal knob, so you can carry one rosette shape across every door in a project and change only the knob style where you want to.
21) What is a decorative passage knob alternative to the Emtek Lowell if I want a metal knob in a named design?
The Bravura Dallas with rectangle trim is a passage knobset in US4 satin brass, Grade 2, and the Emtek Lowell also offers a Satin Brass (US4) finish, so the two can sit near each other in the same finish family. The Sure-Loc Arapaho knob and the Sure-Loc modern Bergen round knob are further knob designs if the Lowell crystal knob is not the look for the room.
