Emtek 8459-US26 – Frequently Asked Questions

1) What backset do I need for the Emtek 8459 deadbolt, and can I get 2-3/4 inch?
Both. The standard latch is 2-3/8 inch backset, and 2-3/4 inch is a selectable option at no change to the model number. Measure from the door edge to the center of the 2-1/8 inch cross bore: on residential doors that is usually 2-3/8 inch, and on wider-stile or older doors 2-3/4 inch. Pick the backset on the order form, since the wrong latch will not reach the bore.
2) I have Weiser locks on the rest of the house. Does Emtek make the 8459 in a Weiser keyway?
Yes. The Knoxville 8459 is offered with a Weiser WR5 cylinder, ordered by putting a W in front of the product code (W8459). There is no upcharge for the cylinder substitution, and it can be keyed into an existing Weiser system. That is the version to pick if the other doors are already Weiser keyed.
3) What door prep does the Emtek 8459 need, and will it drop into my existing deadbolt hole?
Standard tubular deadbolt prep: a 2-1/8 inch cross bore through the face and a 1 inch edge bore. That is the same prep the vast majority of residential deadbolts use, so on a door already bored for a standard deadbolt it goes straight in as long as the existing backset matches the 2-3/8 inch or 2-3/4 inch latch you order. No new boring on a typical replacement.
4) Is the Emtek 8459 deadbolt suitable for a commercial entrance or an apartment building?
The Knoxville 8459 is a residential-duty solid brass deadbolt, best suited to single-family and high-end residential entries where the look matters. For commercial openings or heavy multi-family traffic, look at a Grade 1 or Grade 2 commercial deadbolt instead: the Hager 3115 is a Grade 2 cylinder x thumbturn deadbolt that also uses the Schlage C keyway, so it keys into the same system, and the Accentra D111 is a Grade 1 single cylinder deadbolt with a 2-3/8 inch backset.
5) My door is 2-1/4 inches thick. Will the Emtek 8459 work?
No. The mechanical 8459 Knoxville tops out at a 2 inch door. Emtek's EMPowered version of the Knoxville deadbolt is the one rated to 2-1/4 inches. For a thick commercial door, the Corbin Russwin DL3011 Grade 1 cylindrical deadlock covers 1-3/4 inch to 2-1/4 inch.
6) What is the closest deadbolt to the Emtek 8459 that keys into an existing Schlage C system?
The 8459 Knoxville ships standard with a Schlage C keyway, and a Weiser WR5 cylinder is available by adding a W to the front of the product code. If a Schlage C deadbolt is needed in a plainer commercial trim, the Hager 3115 is a Grade 2 cylinder x thumbturn deadbolt with a Schlage C keyway for 1-3/8 to 1-3/4 inch doors, and the Hager 3118 is a Grade 1 classroom deadbolt with a Schlage C keyway and a 6-pin cylinder. The Dormakaba D900 small case mortise deadbolt is also supplied with SC keyways, but it is a mortise case rather than the tubular bore the Emtek uses.
7) I need a double cylinder deadbolt for a glass panel door, not a thumbturn. What takes the place of the Knoxville 8459?
The 8459 Knoxville is single cylinder, keyed outside with a thumbturn inside, so it will not satisfy an opening that requires a key on both faces. For double cylinder operation, the Baldwin Reserve Double Cylinder Contemporary Round and Contemporary Square deadbolts are keyed on both sides, as is the Baldwin Estates 8011 Contemporary 1-5/8 inch double cylinder deadbolt. On the commercial side, the Dexter DB1000 double cylinder is Grade 1 for 1-3/8 to 1-7/8 inch doors, the Dexter DB2000 double cylinder is Grade 2 for 1-3/8 to 1-3/4 inch doors, and the Hager 3214 is a Grade 2 double cylinder with a Schlage C keyway. Local code often restricts double cylinder deadbolts on required egress doors, so confirm before specifying.
8) What is a Grade 1 alternative to the Emtek 8459 Knoxville deadbolt for a heavier-traffic opening?
The Emtek 8459 Knoxville is a single cylinder deadbolt, cylinder x thumbturn, with a solid brass housing, collar, thumbturn and rosette and a hardened steel bolt. If the opening calls for an ANSI/BHMA Grade 1 deadbolt in the same cylinder x thumbturn function, the Accentra D111 is a Grade 1 single cylinder deadbolt in the D Series with a 2-3/8 inch backset and a door thickness range of 1-3/8 to 1-3/4 inch. The Dexter DB1000 single cylinder is also Grade 1 cylinder x thumbturn and covers 1-3/8 to 1-7/8 inch doors. The Emtek is a decorative brass residential deadbolt; the Accentra and Dexter are plain-trim commercial units.
9) Which deadbolt should I use if the door is fire rated?
The Emtek 8459 Knoxville is a residential brass deadbolt. For an opening where a fire rating is required, the Hager 3115 is a Grade 2 cylinder x thumbturn deadbolt with a Schlage C keyway, a fire rating, and a 1-3/8 to 1-3/4 inch door thickness range, and the Hager 3215 is a fire rated Grade 2 single cylinder deadbolt with a 1 inch throw. The Cal-Royal CRB800 is a Grade 1 heavy duty single cylinder deadbolt with a UL 3-hour fire rated latch. All three keep the same cylinder x thumbturn operation as the 8459, and the two Hager units share its Schlage C keyway, so an existing Schlage keying system carries over.
10) The backset on the existing door is unknown. Which deadbolt handles either one without ordering a specific version?
The Emtek 8459 Knoxville is ordered to a backset: 2-3/8 inch standard, or 2-3/4 inch if specified. If the backset has to be settled at the door instead of at the order, the Brinks Raleigh round and Brinks Mendocino square single cylinder deadbolts both have a 4 way adjustable backset in the same cylinder x thumbturn function, the Cal-Royal ED500 is a Grade 3 single cylinder deadbolt with adjustable backset for 1-3/8 to 1-3/4 inch doors, and the Falcon D111 is a Grade 1 heavy duty classroom deadbolt with adjustable backset.
11) What deadbolt works instead of the Emtek 8459 on a door thicker than 2 inches?
The 8459 Knoxville is specified for 1-3/8 to 2 inch doors, standard at 1-3/4 inch, with an extension collar included for thin doors. For a thicker door, the Corbin Russwin DL3011 Grade 1 cylindrical deadlock covers 1-3/4 to 2-1/4 inch. Note that the DL3011 is a cylinder x blank deadlock, keyed outside with no thumbturn inside, so it changes how the door is operated from the secure side rather than being a straight swap.
12) Which deadbolts accept an interchangeable core instead of a fixed cylinder like the Emtek 8459?
The 8459 Knoxville ships with a fixed Schlage C cylinder, or a Weiser WR5 cylinder ordered with a W prefix, and is keyed at the factory keyed alike or keyed different. Where a facility runs interchangeable cores instead, the Deltana CL200LAIC is a Grade 2 single cylinder deadbolt prepped for an interchangeable core and supplied without the cylinder, the Arrow E61 is a Grade 2 single cylinder deadlock with SFIC prep less core for 1-3/8 to 1-3/4 inch doors, and the Delaney LM Series is a Grade 1 single cylinder less core deadbolt in Dull Chrome US26D. Those let a locksmith core them into an existing masterkey system on site.
13) What deadbolt should I use on a door that needs a thumbturn inside but no key outside?
The 8459 Knoxville is keyed outside with a thumbturn inside. If the outside face should not be keyed, the Arrow E60 is a Grade 2 non-keyed exit deadlock with a blank plate outside and thumbturn inside for 1-3/8 to 1-3/4 inch doors. If the reverse is needed, keyed outside with a blank inside, the Corbin Russwin DL3211 is a Grade 1 cylindrical deadlock with cylinder x blank for 1-3/4 inch doors, and the Callan Model 205S is a Grade 3 one sided half-bore deadbolt for doors bored on one face only.
14) Do I need to know the handing to order an Emtek Knoxville deadbolt?
No handing needed. The 8459 is a deadbolt with a key cylinder outside and a thumbturn inside, so it works on a left or right hand door either way. Order the finish, keyway and backset and you are done.
15) What comes in the box with the Emtek 8459 deadbolt?
Every 8459 ships with the cylinder, housing, collar, thumbturn and rosette in solid brass, a hardened steel bolt, a heavy gauge steel understrike, and a brass trim strike. The thin-door extension collar is included as well. You supply nothing beyond screws-in-the-box hardware and the strike prep in the jamb.
16) Is the Emtek Knoxville deadbolt solid brass or plated?
Solid brass through the cylinder, housing, collar, thumbturn and rosette, not a plated zinc casting. The bolt itself is hardened steel and the understrike behind the jamb plate is heavy gauge steel. That is why the unlacquered brass finish can be left to patina rather than wearing through to a base metal.
17) Can I key several Emtek Knoxville deadbolts alike across a set of doors?
Yes. Keyed alike is a free option, so a front, back and side door can all run on one key. If you are adding to a system that already exists, put the key code in the keying-to-code field and the cylinders get cut to match. Both the Schlage C and Weiser WR5 cylinders can be keyed into an existing system of that keyway.
18) Is a Bravura 310B Elite the same thing as an Emtek 8459 Knoxville?
Both are single cylinder residential-style deadbolts in the same cylinder x thumbturn function, but they are not the same part. The Bravura 310B Elite is a Grade 2 traditional round deadbolt in the 310B Elite series; Bravura also lists the 310RC round and 310SC square contemporary versions at Grade 2. The Emtek 8459 Knoxville is built in solid brass through the cylinder, housing, collar, thumbturn and rosette, ships with a brass trim strike and a heavy gauge steel understrike, and offers seven finishes from Oil Rubbed Bronze (US10B) to Unlacquered Brass (US3NL). Order by the exact model when a facility is standardizing trim.
19) I want keypad or fob entry instead of a keyed deadbolt like the 8459. What are the options?
The 8459 Knoxville is a keyed mechanical deadbolt, not electronic. For credential-based entry in the same deadbolt footprint, the Delaney KP400 is a Grade 2 electronic deadbolt with a programmable remote, the Codelocks CL2200 is an electronic surface deadbolt in brushed steel and the CL2210 is an electronic mortise deadbolt, and Dormakaba offers the Saffire LX-D RFID electronic deadbolt with BLE and electronic lock override and the Nova-D RFID multihousing smart deadbolt. These use different door preps than the standard tubular bore the Emtek uses, so verify the prep against the existing door.
20) Is the BEST 8T tubular deadbolt an alternative to the Emtek 8459?
No. The BEST 8T is the T Series tubular deadbolt tube component, the bolt mechanism itself rather than a complete keyed deadbolt with outside trim and inside thumbturn. The Emtek 8459 Knoxville is a complete single cylinder deadbolt supplied with the brass cylinder, housing, collar, thumbturn and rosette, a hardened steel bolt, a heavy gauge steel understrike and a brass trim strike. The same caution applies to the Baldwin Reserve 8BR0618001, which is a deadbolt spacer, and the Arrow 460, a mortise lock strike for latchbolt and deadbolt functions - both are accessories, not deadbolts.
21) Is there a deadbolt with an easier-to-grip thumbturn for an accessible unit?
The Emtek 8459 Knoxville uses a solid brass thumbturn matched to the Knoxville trim. Where an easier grip is wanted on the inside face, the Cal-Royal LSD is a Grade 3 single cylinder deadbolt with an ADA ergonomic thumbturn for 1-3/8 to 1-3/4 inch doors, in the same cylinder x thumbturn function as the 8459. The Cal-Royal CB160 is another Grade 2 single cylinder option and adds a tamper-resistant cylinder guard on the outside face.
22) The door already has a keyed entry lockset. Do I still need a separate deadbolt like the 8459?
The Emtek 8459 Knoxville is a standalone tubular deadbolt bored separately above the lockset, with a 2-1/8 inch cross bore and a 1 inch edge bore. If one unit covering both latch and deadbolt is preferred, the Falcon H2101 is a Grade 2 entrance interconnected lock with a single cylinder deadbolt, which combines the latch and the deadbolt in one assembly and retracts them together. That is a different door prep than the separate deadbolt bore the 8459 uses.
23) What finishes does the Emtek Knoxville 8459 deadbolt come in?
Seven: Oil Rubbed Bronze (US10B), Satin Nickel (US15), Pewter (US15A), Polished Chrome (US26), Polished Brass Lifetime (US3), Unlacquered Brass (US3NL) and French Antique (US7). All seven are offered in either the Schlage C or the Weiser WR5 cylinder, so the keyway choice does not limit the finish. Unlacquered brass is the one that will patina over time rather than hold its shine; the rest are coated finishes.
24) What is the difference between the Emtek 8459 Knoxville deadbolt and a builder-grade deadbolt from the box store?
Three things separate them. The 8459 is solid brass rather than plated zinc, it comes in seven architectural finishes including unlacquered brass and French antique, and the cylinder can be ordered in Schlage C or Weiser WR5 so it drops into an existing key system. A budget deadbolt with an adjustable backset, like the Brinks Raleigh Series round single cylinder, covers both backsets in one box but is not a solid brass decorative trim.
