Emtek 8100.AS.US15 – Frequently Asked Questions

1) Will the Emtek Astoria crystal passage knob fit a standard 2-1/8 inch bored door?
Yes, standard prep works. The Astoria passage set drops into any door from 1-3/8 to 2-1/4 inches thick with a 2-1/8 inch cross bore, which is the normal prep on an interior door. The only exception is the STRETTO rosette, which needs a 1-1/4 inch diameter bore and a 2-hole prep. If your existing door was drilled for a tubular knob set, no new boring is needed.
2) What backset do I need to order for an Emtek Astoria passage knob?
Backset is a required choice at 2-3/8 or 2-3/4 inches. The 2-3/8 inch latch is the standard shipment, so if your door was bored with the hole centered 2-3/4 inches from the door edge you have to specify that instead. Measure from the edge of the door to the center of the 2-1/8 inch bore before ordering.
3) Does a passage knob lock, or do I need a privacy set for a bedroom or bath?
Passage function means it never locks. The Astoria knob latches the door and turns freely from both sides, which is what you want on a hall, closet, or a door between rooms. For a bedroom or bathroom you need a privacy set with a thumbturn instead. It is also non-keyed, so it is not an option for an exterior or a door you need to secure.
4) What comes in the box with the Emtek Astoria knob set, and do I need to buy a latch separately?
It ships as a complete set: both knobs, the rosettes, the latch, and the strike plate. Nothing else is required to hang it on a properly bored door. The latch faceplate is available in round corner or square corner, so match it to the mortise already cut in your door edge rather than re-chiseling.
5) Is a crystal knob like the Emtek Astoria suitable for a commercial or high traffic building?
No, it is built for residential use, and the glass and porcelain construction is a decorative choice rather than a duty-rated one. For an office, school, or apartment common area you want a graded cylindrical lock instead: the Schlage D10S is a Grade 1 heavy duty passage knob, the Corbin Russwin CK4310 is Grade 1 passage/closet, and the Falcon W101 is a Grade 2 passage knob with a fire rating. Keep the Astoria for private residences and unit interiors.
6) My door is 2 inches thick. What passage knob will fit?
The Astoria set covers 1-3/8 up to 2-1/4 inches, so a 2 inch door is inside its range. If you want a graded alternative at that thickness, the Corbin Russwin CK4310 Grade 1 passage lock is rated 1-3/8 to 2 inches and the Falcon X101 Grade 1 passage knobset goes to 2-1/4 inches. Most graded Grade 2 and Grade 3 knobs stop at 1-3/4 inches, so a thick door narrows the field quickly.
7) What is the closest commercial-grade equivalent to an Emtek Astoria passage knob set?
The Astoria is a residential passage knob set with a tubular lock mechanism, so the nearest commercial-graded counterpart is a cylindrical passage knob lock. The Schlage D10S is a Grade 1 heavy duty passage knob lock with an Orbit knob, and the Corbin Russwin CK4310 is a Grade 1 passage/closet cylindrical lock with a Global knob that fits doors 1-3/8 inch to 2 inch thick. Both do the same job at the door - latch only, no locking - but they carry cast metal knob designs rather than the cut crystal knob and interchangeable brass rosette that define the Astoria.
8) The Astoria passage set will not work on my bedroom door - what do I use for a room that needs to lock?
A passage set latches only and has no locking mechanism, so a bedroom or bathroom needs a privacy function knob. The Baldwin Estate 5000 Baltimore privacy knob uses a 5148 rose with a 2-3/8 inch backset and full lip strike, the Deltana 6112 St. Thomas privacy knob fits doors 1-3/8 inch to 2 inch thick, and the Dexter C2000 privacy knob is Grade 2 for doors 1-3/8 inch to 1-3/4 inch. The Baldwin 5077 Bethpage privacy knob with R027 rose is another decorative-tier option.
9) What do I order for an exterior door if I like the Astoria look?
The Astoria is non-keyed, so an entry opening needs a keyed knob instead. In the decorative solid brass tier the Deltana 3381 Egg Knob entry and Deltana 6171 Round Knob entry both cover doors 1-3/8 inch to 2 inch thick, and the Deltana 6901 Portland Knob entry covers 1-3/8 inch to 1-3/4 inch. On the builder side the Kwikset 400P-CP Polo keyed entry knob is Grade 3 for 1-3/8 inch to 1-3/4 inch doors with a round corner adjustable latch and strike.
10) Is a dummy knob the same thing as an Emtek Astoria passage knob?
No. The Astoria passage set includes a latch and strike plate and the knob retracts that latch. A dummy knob is surface mounted trim with no latch and no moving mechanism - it is for a door held by a ball catch or roller, or for the inactive leaf of a pair. The Schlage A170 is a Grade 2 single dummy trim for doors 1-3/8 inch to 1-7/8 inch, the BEST 6K single dummy trim is a Grade 2 medium duty knob, and the Omnia 434/0 egg-shaped single dummy is solid brass. Ordering one of those where a passage set belongs leaves the door with nothing to hold it closed.
11) Which passage knob should I spec for a high-traffic commercial corridor instead of a decorative brass one?
The Astoria is a residential knob set. For corridor and stairwell traffic, the Falcon X101 is a Grade 1 heavy duty cylindrical passage knobset that is fire rated and fits doors 1-3/8 inch to 2-1/4 inch, and the Falcon W101 is a Grade 2 medium duty fire rated passage/closet knob lock with a 2-3/4 inch backset. The Schlage D10S passage knob is Grade 1 heavy duty in the D Series. Those carry ANSI grading and fire ratings that a residential decorative set does not.
12) I am standardizing knobs across a building and need one family covering passage, privacy and entry - what covers all three?
The Emtek Astoria set is a passage function only. For a single family spanning all three, the Dexter C2000 Series runs Grade 2 cylindrical ball knobs in passage, privacy, entry/office and classroom functions, all over 1-3/8 inch to 1-3/4 inch doors. The Pamex FTF Baron covers passage, privacy and entrance/office at Grade 3 across the same door range. The Corbin Russwin 4000 family runs the CK4310 Grade 1 passage and the CK4851 entrance/office with a conventional cylinder for doors 1-3/8 inch to 2 inch.
13) What is the difference between the standard latch, the 28 degree latch, and the CF mechanism on Emtek knobs?
Three choices, and they change how the knob feels and looks. The standard latch is the conventional throw. The 28 degree rotation latch retracts with less knob turn, which suits a crystal knob you grip lightly. The CF mechanism gives you rosettes with no exposed screws for a clean face, and it includes the 28 degree latch. Pick CF if the screw heads on the rose would bother you.
14) Can I match the Emtek Astoria crystal knob to the other door hardware in my 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). The metal parts are brass. Seven rosette shapes are available too, from the round Regular to the Rectangular, Oval, Quincy, Watford, Wilshire and #8, so the rose can be matched to the trim style on the rest of the openings.
15) I want a decorative brass passage knob but not glass. What else is there?
Several solid brass traditional knobs cover the same look without the crystal. The Omnia 434/PA is a passage latchset with an egg-shaped knob in solid brass, and the Baldwin Estate 5011 Colonial passage knob with the 5058 rose is another traditional option. The Baldwin Estate 5000 Baltimore passage set comes preconfigured with a 2-3/8 inch backset and a full lip strike if you want the ordering decisions already made for you.
16) I need a plain passage knob for a hall closet, not a crystal one - what else works?
For a hall or closet door where the decorative knob is not the point, the Dexter C2000 Series passage knob is a Grade 2 cylindrical ball knob for doors 1-3/8 inch to 1-3/4 inch thick, and the Pamex FTF Baron is a Grade 3 passage knob lockset over the same door thickness range. The Kwikset 200P Polo passage knob covers interior hall and closet openings and ships with a 6AL latch and round corner strike. All three latch without locking, the same function the Emtek Astoria performs, in a turned metal knob instead of cut crystal.
17) Is there a solid brass passage knob alternative to the Emtek Astoria without the crystal knob?
Yes. The Omnia 434/PA is a traditional egg-shaped knob latchset in solid brass with a 3 inch projection, performing the same passage function. The Emtek Astoria is a brass knob set as well, but its knob is from the Glass and Porcelain collection with a cut crystal knob on brass rosettes, where the Omnia is brass throughout.
18) Can I use a keyless combination lock in place of a passage knob on an interior door?
They are not the same device. The Lockey 3830 is a mechanical keyless combination knob lock with an auto-locking passage function for doors 1 3/16 inch to 2 inch thick, meaning it relocks itself and requires a code from the outside. The Emtek Astoria passage set is non-keyed and simply latches, with the knob turning freely from either side. If the requirement is controlled access on an interior door, the Lockey answers it; if the requirement is a knob that always opens, it does not substitute.
19) What is a lower-cost passage knob that still takes a 2-3/8 inch or 2-3/4 inch backset like the Astoria?
The Astoria backset is adjustable between 2-3/8 inch and 2-3/4 inch. The Kwikset 200P-CP Polo passage knob ships with a round corner adjustable latch and round corner strike, and the Schlage Residential F500 Plymouth with Georgian knob comes as a combo pack with adjustable backsets and dual strikes for doors 1-3/8 inch to 1-3/4 inch. Both handle either standard backset on a builder-grade knob rather than a crystal one.
20) Does a storeroom knob lock do what an Astoria passage set does?
No. A storeroom function knob keeps the outside knob locked at all times and requires a key to enter, while the inside knob always exits. The Sargent 6G04 is a Grade 2 storeroom/closet knob lock with a single cylinder and the Sargent 8XG04 is a Grade 1 heavy duty storeroom/closet single cylinder knob with a 2-3/4 inch backset. The Emtek Astoria passage set is non-keyed and turns freely from both sides, so a storeroom lock is the choice only when the closet must stay secured.
21) Can I get the Astoria knob in a different finish inside than outside?
Split finish is available as an ordering option on the Astoria set, so one side can be specified differently from the other. That is the usual move when a hallway is one metal and the room behind the door is another. Give the two finishes when you order, and note the actual door thickness if it is anything other than standard.
22) What decorative passage knob comes in a satin brass finish besides the Emtek Astoria?
The Astoria passage set is offered in Satin Brass (US4) among ten finishes including Flat Black (US19), Oil Rubbed Bronze (US10B), Polished Nickel Lifetime (US14) and Unlacquered Brass (US3NL). The Bravura Dallas with Rectangle Trim passage knobset is a Grade 2 knob supplied in US4 Satin Brass, giving a matching finish designation on a solid metal knob.
23) Are there round-rose passage knob alternatives to the Emtek Astoria for a matching set of interior doors?
Yes. The Bravura Albany and the Bravura Lynchburg are both Grade 2 passage knobsets with round trim, and the Arrow MK01 is a Grade 2 passage/hall/closet cylindrical knob lock for doors 1-3/8 inch to 1-3/4 inch, with the Arrow RK01 the ball knob version at the same grade and door range. The Astoria reaches a round profile through its Regular or Oval rosette while keeping the crystal knob.
