Emtek EMP28459-US15 – Frequently Asked Questions
1) Will the Emtek Knoxville EMPowered deadbolt fit my door thickness?
The Knoxville deadbolt is built for a standard 1-3/4 inch door, and the spec range runs 1-3/8 inch to 2 inch. Thinner doors are covered by the extension collar that ships with the single cylinder version. With the EMPowered upgrade the assembly handles doors up to 2-1/4 inch. If your door is anything other than 1-3/4 inch, state the thickness on the order using the Door Thickness field so the right collar and tailpiece length come with it.
2) What door prep does the Emtek Knoxville deadbolt need, and will it drop into my existing bore?
Standard residential prep: 2-1/8 inch cross bore, 1 inch edge bore, with a 2-3/8 inch or 2-3/4 inch backset. That is the same prep most existing tubular deadbolts use, so on a door already bored for one it goes back in without new holes. Backset is a required choice at order time, so measure from the door edge to the center of the bore before you pick.
3) Can the Emtek Knoxville deadbolt be keyed into my existing Schlage or Weiser system?
Both keyways are offered. Standard is the Schlage C keyway; the Weiser WR5 cylinder is the alternate and there is no upcharge for the substitution, so it can be keyed into an existing Weiser system. Keyed alike or keyed different is a required selection, and there is a keying-to-code field if you need it cut to a specific code for a building that is already on a master.
4) I have a 2-3/4 inch backset door; can I still use the Knoxville deadbolt?
Yes. The standard latch ships for a 2-3/8 inch backset, and a 2-3/4 inch latch is available and selected at order time. Pick it on the required Backset option rather than assuming the standard one will reach; on a thicker stile door the 2-3/4 inch is usually what the existing prep calls for.
5) What is a non-electronic equivalent to the Emtek EMP8459 Knoxville single cylinder deadbolt for a residential opening?
The Emtek EMP8459 Knoxville is an electronic single cylinder deadbolt in a cylinder x thumbturn configuration with a Schlage C keyway. If the opening does not need the electronic function, the Hager 3115 is a mechanical cylinder x thumbturn deadbolt also built around a Schlage C keyway, fitting doors 1-3/8 inch to 1-3/4 inch. The Dexter DB1000-SCT is another mechanical cylinder x thumbturn option, Grade 1, for doors 1-3/8 inch to 1-7/8 inch. Both are keyed mechanical bolts with no keypad or electronic credential.
6) Which deadbolts are alternatives to the Emtek EMP8459 if I need an electronic lock for multifamily or hospitality?
The Emtek EMP8459 Knoxville is an electronic deadbolt in the EMPowered series, built for residential use. For property-wide credential management, the Dormakaba Saffire LX-D is an RFID electronic deadbolt with BLE and electronic lock override, and the Dormakaba Nova-D is an RFID multihousing smart electronic deadbolt. The Codelocks CL2200 is an electronic surface deadbolt in a brushed steel finish rated medium duty, mounting to the door face rather than into a standard bored prep.
7) I need a Grade 1 deadbolt for a commercial opening - what should I use instead of the Emtek EMP8459?
The Emtek EMP8459 Knoxville is a residential electronic deadbolt. For a commercial spec calling out Grade 1, the Accentra D111 is a Grade 1 single cylinder cylinder x thumbturn deadbolt with a 2-3/8 inch backset for doors 1-3/8 inch to 1-3/4 inch, the Falcon D111 is a Grade 1 heavy duty deadbolt with adjustable backset, and the Hager 3118 is a Grade 1 classroom deadbolt with a Schlage C keyway and 6-pin cylinder. The Deltana CL200LM is another Grade 1 single cylinder cylinder x thumbturn option.
8) The Emtek EMP8459 is single cylinder - what do I use on a door with glass beside it that needs key operation both sides?
The Emtek EMP8459 Knoxville is a single cylinder deadbolt, keyed outside with a thumbturn inside. Where a key is required on both faces, the Dexter DB1000-DCT is a Grade 1 double cylinder deadbolt for doors 1-3/8 inch to 1-7/8 inch, the Hager 3214 is a Grade 2 double cylinder deadbolt with a Schlage C keyway, and the Baldwin Reserve Contemporary Round and Contemporary Square deadbolts are both double cylinder. Confirm double cylinder is permitted by the egress code for the occupancy before specifying.
9) I key my buildings on small format interchangeable core - what deadbolt should I specify instead of the Emtek EMP8459?
The Emtek EMP8459 Knoxville uses a Schlage C keyway cylinder, with a Weiser WR5 keyway available by adding W to the product code. It is not an interchangeable core product. For SFIC systems, the Arrow E61 26D IC is a Grade 2 single cylinder deadlock with SFIC prep supplied less core for doors 1-3/8 inch to 1-3/4 inch, the Deltana CL200LAIC is a Grade 2 single cylinder deadbolt prepped for interchangeable core with a 2-3/4 inch backset, and the Delaney LM Series 301702 is a Grade 1 single cylinder less core deadbolt in dull chrome.
10) Does the Cal-Royal CRB800 do the same job as the Emtek EMP8459 on a fire rated opening?
The Emtek EMP8459 Knoxville is a residential electronic deadbolt with a hardened steel bolt and heavy gauge steel understrike. Where a fire rated opening is involved, the Cal-Royal CRB800 is a heavy duty single cylinder cylinder x thumbturn deadbolt with a UL 3-hour fire rated latch, and the Hager 3115, 3215, 3214 and 3118 are all carried with a fire rating for doors 1-3/8 inch to 1-3/4 inch. These are mechanical bolts without the electronic function of the Knoxville.
11) Does this Emtek deadbolt key on the outside and thumbturn inside, or is it a double cylinder?
Single cylinder: key outside, thumbturn inside. If you have glass beside or within the door and your local code or insurer pushes you toward a key on both sides, that is a different function; Baldwin's Reserve Contemporary Round and Contemporary Square deadbolts are double cylinder, as is the Callan Model 210S.
12) Do I need to specify handing for the Emtek Knoxville deadbolt?
No handing required. A deadbolt has no latch bevel, so the same unit works on a left or right hand door. What you do have to specify is backset, keyway, finish, keying, and door thickness if it is not 1-3/4 inch.
13) What comes in the box with the Emtek Knoxville deadbolt?
The deadbolt ships with a hardened steel bolt, a heavy gauge steel understrike, and a brass trim strike, so the strike side of the job is covered. Cylinder, housing, collar, thumbturn, and rosette are solid brass. On the single cylinder version an extension collar for thin doors is included as well.
14) Is the Emtek EMPowered Knoxville deadbolt suitable for a commercial opening?
It is a residential product in the EMPowered electronic line, brass trim over a tubular deadbolt. For a commercial entry where a Grade 1 deadbolt is spec'd, look at the Accentra D111, the Delaney LM Series Grade 1, or the Deltana CL200LM instead. For a keypad deadbolt with a commercial pedigree, the Dormakaba Saffire LX-D and Nova-D are RFID electronic deadbolts built for multihousing.
15) What is the difference between the Emtek EMPowered Knoxville and a plain mechanical brass deadbolt?
Same Knoxville brass trim and same standard tubular prep, but the EMPowered upgrade makes it an electronic lock rather than key-only, which is why it accommodates doors up to 2-1/4 inch where the mechanical spec stops at 2 inch. If you only want key and thumbturn on a residential door, a straight mechanical deadbolt such as the Bravura 310B Elite or a Dexter DB1000 single cylinder covers that at 1-3/8 to 1-7/8 inch thickness.
16) What deadbolt handles a door thicker than the Emtek EMP8459 EMPowered range?
The Emtek EMP8459 Knoxville EMPowered fits doors up to 2-1/4 inch, with the standard mechanical prep covering 1-3/8 inch to 2 inch. For thicker commercial doors in that same upper range, the Corbin Russwin DL3011 Grade 1 cylindrical deadlock covers 1-3/4 inch to 2-1/4 inch, though it is a cylinder x blank configuration rather than cylinder x thumbturn. The Deltana 7312KA2 covers 1-3/8 inch to 2 inch as a double cylinder Grade 3 bolt.
17) Is the Arrow E60 a substitute for the Emtek EMP8459 Knoxville deadbolt?
No. The Emtek EMP8459 Knoxville is a keyed single cylinder deadbolt, key outside and thumbturn inside. The Arrow E60 is a Grade 2 exit deadlock that is non-keyed, with a blank plate on the outside and a thumbturn inside, for doors 1-3/8 inch to 1-3/4 inch. It gives no key access from outside. If a keyed Arrow is wanted instead, the DBX61 is a Grade 2 single cylinder cylinder x thumbturn deadbolt.
18) What deadbolt should I pick instead of the Emtek EMP8459 if I need an easier-to-grip thumbturn for accessibility?
The Emtek EMP8459 Knoxville has a solid brass thumbturn matched to its American Designer trim. Where grip is the concern, the Cal-Royal LSD is a Grade 3 single cylinder cylinder x thumbturn deadbolt with an ADA ergonomic thumbturn for doors 1-3/8 inch to 1-3/4 inch. The Cal-Royal ED500 is a Grade 3 single cylinder deadbolt with adjustable backset over the same door thickness range if backset flexibility matters more.
19) The Emtek EMP8459 needs a standard bored door prep - what deadbolt works if I cannot bore the door?
The Emtek EMP8459 Knoxville is a tubular deadbolt using standard door prep with a 2-1/8 inch cross bore and 1 inch edge bore. Where that prep is not possible, the Codelocks CL200 is a surface deadbolt with key override and the Codelocks CL2200 is an electronic surface deadbolt in brushed steel, both mounting to the door face. For a mortise case instead, the Dormakaba D900 is a small case mortise deadbolt with Schlage keyways and the Codelocks CL2210 is an electronic mortise deadbolt.
20) What is a simpler mechanical deadbolt with a contemporary or square trim instead of the Emtek Knoxville?
The Emtek EMP8459 Knoxville is an American Designer style brass deadbolt. For plainer trim shapes in a mechanical bolt, the Bravura 310RC Elite is a Grade 2 contemporary round deadbolt and the 310SC Elite is a Grade 2 contemporary square deadbolt, both cylinder x thumbturn. The Brinks Mendocino E2402 is a contemporary square single cylinder deadbolt with a 4-way adjustable backset, and the Brinks Raleigh E2401 is the transitional round version.
21) Is the Baldwin Reserve 8BR0618001 deadbolt spacer an alternative to the Emtek EMP8459 extension collar?
No, they are not interchangeable. The Emtek EMP8459 Knoxville ships with an extension collar for thin doors as part of the single cylinder deadbolt, and the Knoxville is a complete lock. The Baldwin Reserve 8BR0618001 is a deadbolt spacer component for Baldwin double cylinder deadbolts, not a lock and not fitted to Emtek trim.
