Emtek EMP28478-US15 – Frequently Asked Questions

1) Will the Emtek EMP8478 Quincy deadbolt fit my existing door prep, or does it need special boring?
Standard prep. The Quincy EMPowered deadbolt uses a 2-1/8 inch cross bore and a 1 inch edge bore, and it drives either a 2-3/8 inch or 2-3/4 inch backset, so it drops into a door already bored for a normal tubular deadbolt. Handing is not required, so the same unit works on a left or right hand door.
2) What door thickness does the Emtek Quincy EMPowered deadbolt handle?
The deadbolt covers 1-3/8 inch through 2 inch doors, and an extension collar for thin doors ships with the single cylinder version. With the EMPowered electronic upgrade the assembly is rated for door thickness up to 2-1/4 inches, which covers most thick entry doors and custom slabs.
3) Can the Emtek EMP8478 deadbolt be keyed into my existing Schlage or Weiser keys?
Both keyways are offered. The standard cylinder is Schlage C, and a Weiser WR5 cylinder is available with no upcharge for the substitution, so it can be keyed into an existing Weiser system. On Emtek's product coding the Weiser version is specified by adding a W to the front of the product code.
4) What is a comparable electronic deadbolt if the Emtek EMP8478 Quincy is not the right fit?
The Emtek EMP8478 Quincy is an electronic deadbolt in the EMPowered series with a cylinder x thumbturn function and a Schlage C keyway cylinder. If you want another electronic deadbolt, the Delaney KP400 is a Grade 2 electronic deadbolt with a programmable remote, and the Codelocks CL2200 is an electronic surface deadbolt in a brushed steel finish rated medium duty. The Codelocks CL2210 is an electronic mortise deadbolt, so it needs mortise door prep rather than the standard cross bore and edge bore prep the Quincy uses.
5) I want the same single cylinder deadbolt function without the electronics - what should I order?
The Emtek EMP8478 Quincy is a keyed single cylinder deadbolt, cylinder outside and thumbturn inside. For that same function as a straight mechanical lock, the Dexter DB2000 single cylinder deadbolt is Grade 2 and fits 1-3/8 inch to 1-3/4 inch doors, and the Dexter DB1000 single cylinder is Grade 1 and covers 1-3/8 inch to 1-7/8 inch. Bravura's 310B Elite is a Grade 2 traditional round single cylinder deadbolt if you want a round rosette look.
6) The Emtek Quincy is residential rated - what do I use on a commercial opening instead?
The Emtek EMP8478 Quincy is classified residential. For a commercial opening, the Cal-Royal CRB800 is a heavy duty single cylinder deadbolt with a UL 3-hour fire rated latch, the Hager 3215 is a Grade 2 single cylinder deadbolt with a 1 inch throw and a fire rating, and the Accentra D111 is a Grade 1 single cylinder deadbolt with a 2-3/8 inch backset for 1-3/8 inch to 1-3/4 inch doors. All three are cylinder x thumbturn like the Quincy.
7) I need a double cylinder deadbolt for a door with glass - is the Emtek EMP8478 available that way?
The Emtek EMP8478 Quincy is a single cylinder deadbolt, keyed outside with a thumbturn inside. For keyed operation on both sides, the Baldwin Reserve double cylinder contemporary round and contemporary square deadbolts are double cylinder, the Dexter DB2000 double cylinder is Grade 2 for 1-3/8 inch to 1-3/4 inch doors, and the Delaney LU Series double cylinder is Grade 2 in stainless steel US32D. Confirm your local code permits double cylinder on an egress door.
8) My building keys to an interchangeable core system - what deadbolt works instead of the Emtek Quincy?
The Emtek EMP8478 Quincy ships with a Schlage C keyway cylinder, or a Weiser WR5 keyway by adding a W to the product code, so it keys into a conventional Schlage or Weiser system rather than an IC system. For interchangeable core, the Arrow E61 is a Grade 2 single cylinder deadlock with SFIC prep less core for 1-3/8 inch to 1-3/4 inch doors, the Deltana CL200LAIC is a Grade 2 single deadbolt with interchangeable core prep and a 2-3/4 inch backset, and the Delaney LM Series is a Grade 1 single cylinder less core deadbolt in dull chrome US26D.
9) Which alternatives to the Emtek EMP8478 also use a Schlage C keyway so I can key them into my existing system?
The Emtek EMP8478 Quincy comes standard with a Schlage C keyway and can be ordered keyed alike or keyed to an existing code. Among other deadbolts on a Schlage C keyway, the Hager 3115 is a Grade 2 cylinder x thumbturn for 1-3/8 inch to 1-3/4 inch doors, the Hager 3214 is the double cylinder version, and the Hager 3118 is a Grade 1 classroom deadbolt with a 6-pin cylinder.
10) I'm doing several doors in one house. Can the Quincy deadbolts be keyed alike?
Yes. Keying is selected at order time: keyed different or keyed alike, at no charge, and there is a field to key to a specific code if you are matching an existing system. For a property manager standardizing a building, order the whole group keyed alike on the same keyway, Schlage C or Weiser WR5.
11) Is the Emtek EMP8478 a single cylinder deadbolt, and what's on the inside?
Single cylinder: key outside, thumbturn inside. The cylinder, housing, collar, thumbturn and rosette are solid brass, the bolt is hardened steel, and it ships with a heavy gauge steel understrike plus a brass trim strike. If your entry has glass within reach of the turn, a double cylinder deadbolt such as the Baldwin Reserve Contemporary Round is the alternative arrangement.
12) Is this deadbolt suitable for a commercial opening or is it residential?
The Quincy EMPowered deadbolt is a residential tubular deadbolt in solid brass, built for homes and multi-family entry doors. For commercial or institutional openings where a graded product is specified, look at Grade 1 or Grade 2 tubular deadbolts such as the Accentra D111 (Grade 1, 2-3/8 inch backset, 1-3/8 to 1-3/4 inch doors) or the Hager 3215 Grade 2 with Schlage C keyway.
13) What is the EMPowered upgrade on this Quincy deadbolt actually adding?
It makes the deadbolt an electronic lock rather than a key-only mechanical one, while keeping the Quincy brass trim and the keyed cylinder as override. Emtek publishes the EMPowered 2 technical specifications, keypad dimension and door thickness sheet, entry set installation guide, and the EMTouch programming guide for setup and code management.
14) My doors are thicker than 2 inches - what deadbolt covers that?
The Emtek EMP8478 Quincy is listed for 1-3/8 inch to 2 inch doors in its mechanical prep, with the EMPowered trim fitting up to 2-1/4 inch. If you need a lock built for thick doors from the start, the Corbin Russwin DL3011 Grade 1 cylindrical deadlock covers 1-3/4 inch to 2-1/4 inch, though it is a cylinder by blank plate configuration rather than cylinder x thumbturn.
15) Is the Arrow E60 exit deadlock a substitute for the Emtek EMP8478 Quincy deadbolt?
No. The Emtek EMP8478 Quincy is keyed, with a cylinder outside and a thumbturn inside. The Arrow E60 is a Grade 2 non-keyed exit deadlock with a blank plate outside and a thumbturn inside for 1-3/8 inch to 1-3/4 inch doors, so it gives no outside key access. If you want key control on the outside face, stay with a cylinder x thumbturn lock such as the Arrow DBX61 Grade 2 single cylinder deadbolt.
16) I want a square rosette instead of the Quincy trim - what are my options?
The Emtek EMP8478 Quincy uses a brass rosette in the American Classic style. For square trim in the same cylinder x thumbturn function, the Bravura 310SC Elite is a Grade 2 contemporary square deadbolt, the Callan Model 200S is a Grade 3 single cylinder square trim deadbolt, and the Brinks Mendocino is a contemporary square single cylinder deadbolt with a 4 way adjustable backset.
17) Will the Emtek EMP8478 work on a multifamily door that needs RFID credentials?
The Emtek EMP8478 Quincy is an electronic EMPowered deadbolt with a keyed Schlage C cylinder as the mechanical override. If your program is built around RFID cards, the Dormakaba Nova-D is an RFID multihousing smart electronic deadbolt and the Dormakaba Saffire LX-D is an RFID electronic deadbolt with BLE and electronic lock override.
18) Is a mortise deadbolt like the Dormakaba D900 interchangeable with the Emtek EMP8478?
No. The Emtek EMP8478 Quincy is a tubular deadbolt that installs into a 2-1/8 inch cross bore and a 1 inch edge bore at a 2-3/8 inch or 2-3/4 inch backset. The Dormakaba D900 is a small case mortise deadbolt with a D cylinder, keyed different with SC keyways, and requires a mortise pocket in the door edge. Swapping between the two means changing the door prep.
19) What finishes does the Emtek Quincy EMPowered deadbolt come in?
Five: Oil Rubbed Bronze (US10B), Polished Nickel Lifetime (US14), Satin Nickel (US15), Flat Black (US19), and Polished Chrome (US26). Each is available with either the Schlage C or the Weiser WR5 cylinder, so the keyway choice does not limit the finish.
20) I want to match an electronic deadbolt to the rest of my brass door hardware. Is this the right pick?
That is exactly what the Quincy EMPowered deadbolt is for. Brass cylinder, housing, collar, thumbturn and rosette in an American Classic trim style, so it reads as traditional hardware rather than a plastic keypad lock, and it comes in the same five finishes as the rest of the Emtek line. Electronic deadbolts built around a plain metal housing, like the Delaney KP400 or the Codelocks CL2200 surface deadbolt, do not offer that trim match.
