Emtek 4425-US15 – Frequently Asked Questions

1) Will the Emtek 4425 Jefferson handleset fit my existing door prep?
The Jefferson 4425 handleset uses standard bored prep: a 2-1/8 inch cross bore with 5-1/2 inch center-to-center between the handle bore and the deadbolt bore. Door thickness range is 1-3/8 to 2 inches, so it covers both older 1-3/8 inch doors and standard 1-3/4 inch entry doors. If your door already has a 5-1/2 inch CTC handleset prep, this drops in.
2) What backset do I need to specify for the Emtek Jefferson 4425?
Two backsets are offered, 2-3/8 inch and 2-3/4 inch, and backset is a required selection. The standard latch ships for 2-3/8 inch, so if your existing bore is 2-3/4 inch from the door edge to the center of the hole, you have to call that out on the order. Measure the existing bore before ordering rather than assuming.
3) Does the Emtek 4425 handleset require handing?
Handing is required on the 4425 Jefferson, and you pick right hand or left hand when ordering. Emtek calls for handing whenever a lever is used on the interior or an interconnect device is specified. Get it wrong and the interior lever points the wrong way.
4) What does double cylinder mean on the Emtek 4425, and is it right for a door with glass?
Double cylinder means the deadbolt is keyed on both the outside and the inside, so there is no thumbturn to reach through glass or a sidelite and turn. That is why people choose it on doors with glazing nearby. The tradeoff is egress: anyone inside needs a key to unlock the door, so check your local code for the opening before you commit. If you want a thumbturn inside instead, a single cylinder entry handleset is the version to look at.
5) Can the Emtek Jefferson handleset be keyed into my existing Schlage or Weiser keys?
Standard cylinders are Schlage C keyway, which is what most existing residential Schlage systems use, and free keying options include keyed alike or keyed different plus keying to a code you supply. A Weiser WR5 keyway version is also available at no upcharge for the cylinder substitution, and it can be keyed into an existing Weiser system. Both keyways are offered in all ten finishes.
6) Can I pick the inside knob or lever on the Emtek Jefferson handleset?
Yes, and it is a required choice. The 4425 accepts any Emtek brass knob or lever for the interior trim, and the selection list runs from traditional shapes like Providence, Victoria and Egg knobs to levers such as Milano, Turino, Coventry and Stuttgart, plus crystal knobs like Windsor and Georgetown and knurled or marble options on the L-Square, T-Bar and R-Bar rosettes. Remember that choosing a lever inside makes handing critical.
7) What is a double cylinder alternative to the Emtek 4425 Jefferson handleset if I need a mortise lock body instead of a tubular one?
The Emtek 4425 Jefferson is a tubular handleset in a double cylinder keyed function, with a 2-1/8 inch cross bore and 5-1/2 inch center-to-center door prep. If the opening is prepped for a mortise case rather than a bored tubular lock, the Baldwin Estates 6542 Tremont Double Cylinder Entry Mortise Trim is the double cylinder equivalent in mortise form; Baldwin lists it for 1-3/4 inch doors. The 4425 covers 1-3/8 inch to 2 inch doors, so it suits a wider thickness range, while the Baldwin is the one that drops onto an existing mortise pocket.
8) I only need a key on the outside, not both sides. What is the single cylinder version to order instead of the Emtek 4425?
The Emtek 4425 Jefferson is built as a double cylinder, meaning it is keyed from both faces. If you want a thumbturn inside and a key only outside, the Baldwin Estates 6542 Tremont Single Cylinder Entry Mortise Trim is the single cylinder counterpart to the 6542 double cylinder in the Estates line and is listed for 1-3/4 inch doors, and Schlage Residential's F60 Addison Single Cylinder Keyed Entry Handleset with Accent Lever is a Grade 2 single cylinder option for 1-3/8 to 1-3/4 inch doors. Egress codes in some jurisdictions restrict double cylinder locks on a door with glazing, so confirm the local requirement before specifying.
9) My door is 2 inches thick or more. What handleset should I use instead of the Emtek 4425 Jefferson?
The Emtek 4425 Jefferson is rated for 1-3/8 inch to 2 inch doors, so a thicker slab is outside its range. The Weslock 1411 Traditionale Colonial Handleset with Eleganti Knob is listed for 1-3/4 inch to 2-1/4 inch doors in a single cylinder keyed entry function, and the Yale Real Living BYRD226NRRX Assure Lock Standalone Touchscreen Deadbolt with Ridgefield Handleset also covers 1-3/4 inch to 2-1/4 inch.
10) What comes in the box with the Emtek 4425 Jefferson handleset?
It ships as a complete set including the latch and the strike plate, plus the interior knob or lever you select. You do not buy the cylinder or latch separately. What you do have to decide at order time: interior trim style, handing, backset, and keying.
11) What finishes does the Emtek 4425 Jefferson come in, and can I mix inside and outside?
Ten finishes: Oil Rubbed Bronze (US10B), Lifetime Polished Nickel (US14), Satin Nickel (US15), Pewter (US15A), Flat Black (US19), Polished Chrome (US26), Lifetime Polished Brass (US3), Unlacquered Brass (US3NL), Satin Brass (US4) and French Antique (US7). A split finish option is available if you want the exterior to match the door's other hardware and the interior to match the room.
12) Is the Emtek Jefferson handleset solid brass, and is it meant for commercial use?
Both the material and the substrate are brass, and it is a tubular lock from Emtek's Brass collection in the American Classic style. It is classed as residential, not commercial, so for a high-traffic commercial entrance you want a graded lock instead, such as the Grade 2 Schlage Residential F60 Addison handleset or the Grade 2 Master Lock HDLB Series single cylinder deadbolt handleset.
13) How does the Emtek Jefferson tubular handleset differ from a mortise handleset?
The 4425 is a tubular bored lockset: it installs in a 2-1/8 inch cross bore with a 5-1/2 inch CTC spacing, which is the prep most residential doors already have. A mortise handleset like the Baldwin Estates 6542 Tremont needs a pocket routed into the door edge, which means either a door prepped for mortise or milling the one you have. For a straight replacement on an existing bored door, tubular is the one that goes in without machining.
14) I am furnishing several units and want matching keys. Can the Emtek 4425 be keyed alike across doors?
Yes. Keying is a required order selection with keyed alike or keyed different, and there is also a field for keying to a specific code if you are matching an existing masterkey system. Ordering keyed alike across multiple 4425 handlesets gives one key for the group. The standard Schlage C keyway is the common denominator for most residential systems.
15) Is there a keypad or smart handleset I can use instead of the keyed Emtek 4425 Jefferson?
The Emtek 4425 Jefferson is a mechanical, non-electronic handleset keyed on both sides. For a keypad opening, the Kwikset 815SCEHFL-CP913CNT San Clemente Handleset pairs a Halifax lever interior with a contemporary SmartCode keypad electronic deadbolt for 1-3/4 inch doors, and the Yale Real Living BYRD226CBARX Assure Lock adds Wi-Fi and Bluetooth with a Ridgefield handleset for 1-3/4 inch to 2-1/4 inch doors. Both are credential-based rather than key-only, and neither offers the interior cylinder the 4425 provides.
16) Is there a handleset that fits the same 1-3/8 inch to 2 inch door range as the Emtek 4425?
Yes. The Emtek 4425 Jefferson covers 1-3/8 inch to 2 inch door thickness. The Deltana 810871 Montego Handleset lists the same 1-3/8 inch to 2 inch range, and the Weslock 2810 Hillcrest Single Cylinder Handleset with Hudson Knob does as well. Note the Weslock 2810 is a single cylinder function, so it is a match on thickness but not on the two-sided keying of the 4425.
17) Which handleset looks like the Emtek 4425 but will not lock the door?
Dummy handlesets share the exterior look but have no latch and no cylinder. The Weslock 2815 Hillcrest Dummy Handleset with New Heaven Lever and the Weslock 6695 Belmont Dummy Handleset with Impresa Knob are both dummy function and cover 1-3/8 inch to 2 inch doors. Neither substitutes for the Emtek 4425 Jefferson, which is a keyed double cylinder entry set supplied with latch and strike plate. Use a dummy only on an inactive leaf of a pair.
18) I need a handleset with an adjustable backset instead of specifying 2-3/8 or 2-3/4. What are my options?
The Emtek 4425 Jefferson ships with a 2-3/8 inch backset latch as standard and requires you to specify 2-3/4 inch if the bore calls for it. If you would rather field-adjust, Sure-Loc offers handlesets with adjustable backset in several styles, including the Aspen AN507 keyed entry, the Alta AT507 tubular, the Madison MA507 keyed entry, and the Coral CR507. Those are useful when you are ordering ahead of measuring the existing prep.
19) Does the Emtek 4425 Jefferson carry an ANSI grade, and which comparable handlesets state one?
The Emtek 4425 Jefferson is a residential handleset in solid brass. If a project spec calls out a graded product, the Master Lock HDLB Series HDLBA0615/4D single cylinder deadbolt handleset is stated as Grade 2, as are the Schlage Residential F60 Addison and JE285 Barcelona handlesets, while the Kwikset 687AMD Amador and 687BW Belleview exterior-only handlesets are Grade 3.
20) I need a non-keyed handleset for an interior or screened porch door. What should I order instead of the Emtek 4425?
The Emtek 4425 Jefferson is keyed, and in double cylinder that means a cylinder on both faces. For an opening that does not need a key, the Schlage Residential JE285 Barcelona Style Handleset with Seville Lever is a Grade 2 non-keyed entry function for 1-3/8 inch to 1-3/4 inch doors, which gives you the handleset appearance without any cylinder to key or rekey.
21) Can I use a Kwikset 687 Amador in place of the Emtek 4425 Jefferson?
Not as a direct swap. The Kwikset 687AMD Amador is an exterior-only single cylinder handleset in Grade 3 for 1-3/4 inch doors, supplied without interior trim, and is offered with SmartKey in an SC1 keyway on the 687AMD SMC. The Emtek 4425 Jefferson is a complete double cylinder set that includes latch and strike plate and is ordered with your choice of brass knob or lever for the inside trim, in a Schlage C keyway as standard or Weiser WR5 on request.
22) I want a solid brass handleset but not the Jefferson style. What else is comparable?
The Emtek 4425 Jefferson is a solid brass handleset in an American Classic style. Deltana offers several solid brass entry handlesets in different profiles: the 803871B Hanover, the 815871 St. Ann, and the 825871 Kingston, all entry function. These differ from the 4425 mainly in escutcheon profile and grip shape rather than in material.
