Emtek 5100.E.US15 – Frequently Asked Questions

1) Will the Emtek Egg knob entry set fit a 1-3/8 inch door, and what do I do if my door is thicker than 1-3/4?
The Emtek Egg key-in knobset covers 1-3/8 inch through 1-3/4 inch doors, which takes in both standard commercial-weight residential doors and the thinner older interior doors. It ships set up for 1-3/4 inch as standard, so if your door is thicker than that you have to call it out when you order and the set is built for it. Nothing about the knob or rosette changes, only the spindle and screw pack length.
2) Does the Emtek Egg knob use a 2-3/8 or 2-3/4 inch backset, and will it drop into my existing door prep?
Both backsets are offered on the Egg knobset and you pick one when you order, so it goes into either of the two standard bored preps. The cross bore is 2-1/8 inch, which is the standard cylindrical bore, so a door already prepped for a common tubular knob or lever takes this without redrilling the face. The 2-3/8 inch latch is what ships unless you select 2-3/4 inch. Measure from the door edge to the center of the bore before you order.
3) Can I key the Emtek Egg knobset to my existing house keys?
That depends which keyway your other locks use. The Egg knobset comes with a Schlage C keyway as standard, and Emtek also builds it with a Weiser WR5 cylinder at no upcharge, which can be keyed into an existing Weiser system. So if the rest of the doors are Schlage or Weiser, one key runs the whole set. Keyed alike and keyed different are both free options, and you can supply a key code to have it cut to an existing system.
4) Can I order several Emtek Egg entry knobs all on one key for a rental or a house with two exterior doors?
Yes. Keyed alike is a no-cost option on the Egg knobset, so every set on the order operates from the same key, which is what you want on a front and back door or across a small rental portfolio. Keyed different is the alternative if each door needs its own key. You can also give a key code and have the cylinders cut into an existing system, and the Weiser WR5 cylinder is available at no upcharge to key into an existing Weiser system.
5) The Emtek Egg knobset is residential. What do I use on a commercial entrance door that needs an ANSI grade?
The Emtek Egg knobset is a residential tubular knobset with no ANSI grade behind it, so for a graded commercial entrance use a graded cylindrical knob lock instead. The Corbin Russwin CK4851 is a Grade 1 entrance/office cylindrical knob lock with a conventional cylinder, covering doors 1-3/8 inch to 2 inch. The BEST 8K Series is a Grade 1 heavy duty entrance-function single-cylinder knob lock. If Grade 2 satisfies the spec, the Dexter C2000 entry/office ball knob lock is Grade 2 for 1-3/8 inch to 1-3/4 inch doors. All three are keyed entrance functions like the Emtek Egg, but they are commercial cylindrical chassis rather than a decorative brass residential knob.
6) What is the closest match to the Emtek Egg key-in knobset if I need the same egg-shaped knob in a keyed entry from another brand?
The Deltana 3381 Egg Knob is the nearest equivalent. It is an Egg Knob series knob in an entry function, so it keeps the same egg profile and the same keyed-entry operation as the Emtek Egg knobset, which is an entrance-function single-cylinder knobset. The Deltana 3381 covers doors from 1-3/8 inch to 2 inch thick, while the Emtek Egg is built for 1-3/8 inch to 1-3/4 inch doors, so on a 2 inch door the Deltana is the one that fits without a thick-door cylinder. If the door is in the standard 1-3/8 to 1-3/4 range, either shape works and the decision comes down to keyway: the Emtek Egg is supplied in Schlage C or Weiser WR5 keyway.
7) I have an egg knob on one door and need a matching non-locking knob on the closet next to it. What works?
Look at the Omnia 434 pair. The Omnia 434/PA is a traditional egg-shaped knob latchset in a passage function for a closet or hall door that only needs to latch, and the Omnia 434/0 is the same egg-shaped knob as a single dummy for a door that does not latch at all. Both are solid brass, matching the brass construction of the Emtek Egg knobset. The Emtek Egg itself is keyed single-cylinder entrance only, so for the passage and dummy openings in the same run of doors the Omnia 434 family carries the egg shape through.
8) Which knobsets look like an alternative to the Emtek Egg entrance knobset but will not lock the door?
Several knobs in the same traditional brass look are non-keyed and cannot be substituted for a keyed entrance opening. The Omnia 442/00 and Omnia 458/0 are single dummy latchsets, the Bravura Biloxi is a Grade 2 dummy, the Cal-Royal BA40 is a dummy knob cylindrical lock, and the Schlage A170 is a Grade 2 single dummy trim. A dummy has no latch at all. Passage knobs such as the Baldwin 5011 Colonial with 5058 rose and the Bravura Albany latch but do not lock. Privacy knobs like the Baldwin 5077 Bethpage and the Pamex FTF Baron have a bed and bath push button, not a key. The Emtek Egg is a keyed single-cylinder entrance knobset, so only a keyed entrance product replaces it.
9) I need the outside knob to stay locked at all times with key access. Does the Emtek Egg do that, and if not what does?
The Emtek Egg is an entrance function, which unlocks from the inside and lets the outside knob be left unlocked. For a knob whose outside stays locked continuously and only a key retracts it, use a storeroom function: the Sargent 8XG04 is a Grade 1 heavy duty storeroom/closet single cylinder knob lock with a 2-3/4 inch backset, and the Sargent 6G04 is the Grade 2 standard duty storeroom/closet knob lock with a single cylinder. Both are single cylinder like the Emtek Egg, but the storeroom function is what keeps a mechanical room or supply closet secured behind the key.
10) The door is 2 inches thick. Which keyed knob entry sets cover that?
The Emtek Egg knobset is built for 1-3/8 inch to 1-3/4 inch doors. For a full 2 inch door, the Corbin Russwin CK4851 Grade 1 entrance/office cylindrical knob lock with conventional cylinder covers 1-3/8 inch to 2 inch, and the Deltana 3381 Egg Knob entry covers 1-3/8 inch to 2 inch while keeping the egg-shaped knob. If the thick door is a passage rather than a keyed opening, the Falcon X101 Grade 1 heavy duty cylindrical passage knobset with interchangeable core goes to 2-1/4 inch.
11) The building keys to Kwikset. Can I still use the Emtek Egg knobset, or do I need a different brand?
The Emtek Egg knobset is supplied in the Schlage C keyway as standard or the Weiser WR5 keyway, which is specified by adding a W to the front of the product code and can be keyed into an existing Weiser system at no cylinder upcharge. Neither is a Kwikset keyway. If the building is genuinely on Kwikset, the Cal-Royal BER00 is a Grade 3 entrance/office knob lock supplied with a Kwikset keyway for 1-3/8 inch to 1-3/4 inch doors. Confirm the existing system before ordering, since keyway is not something that can be changed in the field on either product.
12) What does single cylinder mean on the Emtek Egg entry knob, and is it right for a door with glass next to it?
Single cylinder means the key works the outside only; inside there is a turn on the knob, no key. That is the normal entry setup for a front or side door and it lets anyone leave without hunting for a key. Where there is glass within reach of the inside turn, a lot of buyers deliberately avoid a thumbturn-inside lock, and a double cylinder deadbolt above the knob is the usual answer instead. The Egg set itself is only built as a single cylinder entry function.
13) Do I have to specify handing when ordering the Emtek Egg knobset?
For the Egg knob, no. Handing is called out on Emtek leversets, because a lever has to point the right way. A knob is symmetrical, so left hand and right hand doors take the same set, and the latch is reversible in the field the way any cylindrical latch is. If you are ordering Emtek leversets on the same job, those do need the hand called out.
14) Which rosette shapes does the Emtek Egg knob come in, and are there finish restrictions?
Four rosettes back the Egg knob: Classic Brass #8, Rectangular, Regular, and Rope. The Rope rosette is the one with limits, it is not made in Satin Brass (US4), Polished Nickel (US14), or Flat Black (US19). If you are matching Rope trim across a house in one of those three finishes, pick a different rosette. The other three rosettes run the full finish range.
15) What finishes does the Emtek Egg brass knob come in, and which ones will not tarnish?
Ten finishes: 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 two Lifetime finishes, Polished Brass and Polished Nickel, are the ones meant to hold their appearance. Unlacquered Brass is the opposite by design, it is bare brass that will patina with handling. A split finish is also available if you want a different look inside than out.
16) What else can I get in an egg-shaped brass knob if the Emtek Egg entry set is not the right function?
Two other egg knobs are worth knowing. Deltana's 3381 Egg Knob is an entry function set that covers a wider 1-3/8 to 2 inch door thickness range, useful on a thick or built-up door. Omnia's 434 is the same traditional egg shape in solid brass but in non-keyed forms, the 434/PA passage latchset and the 434/0 single dummy, for a closet or a fixed-panel door where no key is wanted. Match the shape across a house by using the keyed Emtek Egg on entry doors and the non-keyed egg knobs elsewhere.
17) I need passage and privacy knobs to match this Emtek entry knob on the other doors, can I get them?
The Egg knob set here is the keyed entry function only, single cylinder. Emtek builds the same Egg knob in passage and privacy for bedrooms, baths, and closets, so a whole house can run one knob and one rosette shape throughout. Order those separately by function and hold the finish and rosette the same across all of them. Note handing is called out on Emtek leversets, so if you mix in levers anywhere, hand those.
18) What is a tubular cylindrical knob lock, and is it enough security on its own for a front door?
The Emtek Egg is a tubular cylindrical lockset, meaning the whole mechanism goes through a 2-1/8 inch bore in the door face with the latch through the edge. That is the fast, standard prep and it is what almost every residential door is already drilled for. It is a latch, not a deadbolt, so on an exterior door it is normally paired with a separate deadbolt above it and keyed alike to the knob. If you want the lock body in a mortise pocket instead of a bore, that is a different lock type entirely and a different door prep.
19) What is a simpler keyed entry knob than the Emtek Egg for a rental unit where the decorative rosette does not matter?
The Kwikset 400P-CP Polo keyed entry knob is a Grade 3 entrance knob for 1-3/8 inch to 1-3/4 inch doors, supplied with a round corner adjustable latch and round corner strike, so the backset is set in the field rather than specified up front. The Master Lock BC Series is another Grade 3 keyed entry knob, with a biscuit knob. Both are plain keyed entry knobs against the Emtek Egg, which is a brass entrance knobset ordered with a specific rosette and a specific 2-3/8 inch or 2-3/4 inch backset. If the units are already on a Weiser system, note that the Emtek Egg can be supplied in the Weiser WR5 keyway to key into it.
20) Is the Deltana 6171 or the Deltana 6901 a substitute for an Emtek Egg knob?
They are the same keyed entry function but a different knob shape. The Deltana 6171 is a Round Knob entry and the Deltana 6901 is a Portland Knob entry, so neither carries the egg profile of the Emtek Egg knobset. Use them when the function is what matters and the knob shape is open. On door thickness the 6171 covers 1-3/8 inch to 2 inch and the 6901 covers 1-3/8 inch to 1-3/4 inch, the same range as the Emtek Egg. For a shape match rather than a function match, the Deltana 3381 Egg Knob entry is the one to pull.
21) Which of the entry knobsets can be ordered in a Satin Brass US4 finish to match existing hardware?
The Emtek Egg knobset is offered in Satin Brass US4 along with Polished Brass Lifetime US3, Unlacquered Brass US3NL, French Antique US7, Oil Rubbed Bronze US10B, Polished Nickel Lifetime US14, Satin Nickel US15, Pewter US15A, Flat Black US19 and Polished Chrome US26. Note that the Rope rosette is not made in US4, US14 or US19, so a Satin Brass order needs the #8, Rectangular or Regular rosette. Among the peers, the Bravura Dallas with rectangle trim is a Grade 2 knobset supplied in US4 Satin Brass, though it is a passage function rather than keyed entry.
22) What is a mid-priced graded entrance knob to standardize on across a building instead of a decorative brass knobset?
For standardizing a building on a graded entrance knob, the Callan Edgewood and Callan Roland are Grade 2 entrance knobsets, and the Callan Canova and Callan Santo are Grade 3 entrance knobsets. The Pamex FTF Baron is a Grade 3 entrance/office knob lockset for 1-3/8 inch to 1-3/4 inch doors, and it has matching Baron privacy and passage versions so one knob design covers every door in the unit. The Emtek Egg is a residential brass entrance knobset supplied only in the keyed single-cylinder function, so a fleet rollout that also needs passage and privacy doors is easier to hold to one look with the Pamex Baron family.
23) Is there a keyless option instead of a keyed egg knob for a back door where keys keep getting lost?
The Lockey 3830 is a mechanical keyless combination knob lock with an auto-locking passage function, fitting doors from 1 3/16 inch to 2 inch. It is opened by combination rather than a cylinder, so there is no key to issue or lose, and it is entirely mechanical with no batteries. The Emtek Egg is a keyed single-cylinder brass entrance knobset in a Schlage C or Weiser WR5 keyway and is non-electronic. Choose the Lockey where credential control matters more than the traditional brass appearance.
24) Which knob lock should go on a classroom door instead of an entrance knobset?
An entrance function like the Emtek Egg knobset lets the inside button hold the outside knob unlocked, which is the wrong behavior for a classroom. The Dexter C2000 Grade 2 classroom cylindrical ball knob lock is keyed for classroom function on 1-3/8 inch to 1-3/4 inch doors, where the outside knob is locked and unlocked by key only and there is no inside button to leave it open. Keep the Emtek Egg for residential entrance doors where that inside control is wanted.
25) I need a fire-rated knob lock. Which of these carry a fire rating?
Among the knob locks, the Falcon W101 is a Grade 2 medium duty cylindrical knob lock with a fire rating, in a passage/closet latch function with a 2-3/4 inch backset, and the Falcon X101 is a Grade 1 heavy duty cylindrical passage knobset with an interchangeable core and a fire rating, covering 1-3/8 inch to 2-1/4 inch doors. Both are passage functions, so if the fire-rated opening also needs to lock, take the fire rating question to a graded keyed chassis rather than a residential brass knobset like the Emtek Egg.
26) What is the difference between the Emtek Egg brass knobset and a builder-grade keyed entry knob like the Kwikset Polo?
Different jobs. The Emtek Egg is solid brass with a choice of four rosette shapes and ten finishes, including Unlacquered Brass that patinas, and it comes with free keying to your existing Schlage C or Weiser system. The Kwikset 400P-CP Polo is a Grade 3 keyed entry knob covering 1-3/8 to 1-3/4 inch doors that ships packaged with its adjustable latch and round corner strike. Buy the Kwikset when it is a functional replacement on an unseen door; buy the Emtek when the hardware is part of the finish schedule.
