Emtek 8457-FB – Frequently Asked Questions
1) What backset and bore does the Emtek 8457 deadbolt need in the door?
Standard prep. Cross bore is 2-1/8 inches, edge bore is 1 inch, and the latch comes for a 2-3/8 inch backset unless you specify 2-3/4. Both backsets are orderable, so measure from the door edge to the center of the existing 2-1/8 inch hole and pick to match. If your door is already bored for a residential deadbolt, the 8457 drops into that prep with no new holes.
2) Can I key the Emtek 8457 deadbolt to my existing Schlage or Kwikset/Weiser keys?
Both keyways are offered. Standard is Schlage C, which keys into an existing Schlage C system. If your building runs Weiser WR5, order the Weiser keyway version (the part number picks up a W prefix, for example W8457MB) at no cylinder upcharge, and it can be keyed into an existing Weiser system. Keyed alike and keyed different are both selectable, and you can supply a key code on the order.
3) Is the Emtek 8457 sandcast bronze deadbolt rated for a commercial entry or apartment corridor?
It is a residential product. Solid brass cylinder, housing, collar, thumbturn and rosette with a hardened steel bolt and heavy gauge steel understrike make it strong for a house or a high-end unit entry, but it carries no commercial grade. For a leased corridor, school, or anywhere the spec calls a grade, go to a graded deadbolt instead: the Accentra D111 is Grade 1 with a 2-3/8 inch backset, the Design Hardware D1 Series is Grade 1 extra heavy duty, and the Hager 3215 is a Grade 2 single cylinder with a 1 inch throw on 1-3/8 to 1-3/4 inch doors.
4) I have doors thicker than 2 inches, will the Emtek 8457 work?
No. The 8457 tops out at 2 inch doors. Thick entry slabs past that need a lock built for the range: the Corbin Russwin DL3011 covers 1-3/4 inch to 2-1/4 inch, and Emtek's EMPowered electronic line reaches 2-1/4 inch, but the mechanical 8457 does not.
5) What is the double cylinder version to order when a glass panel next to the door rules out the Emtek 8457 thumbturn?
The Emtek 8457 is a single cylinder deadbolt, keyed outside and thumbturn inside. Where glass beside or in the door makes an inside thumbturn unacceptable, the substitution is a keyed-both-sides deadbolt. The Hager 3214 is a Grade 2 double cylinder deadbolt with a Schlage C keyway over a 1-3/8 to 1-3/4 inch door thickness range, which keeps the same keyway the 8457 uses. In decorative trim, the Baldwin Estates 8011 is a contemporary 1-5/8 inch double cylinder deadbolt and the Baldwin Reserve double cylinder comes in contemporary round and contemporary square trim. The Deltana 7312KA2 is a Grade 3 double cylinder deadbolt covering 1-3/8 to 2 inch doors.
6) What is the closest single cylinder deadbolt to the Emtek 8457 sandcast bronze if a commercial ANSI grade is required?
The Emtek 8457 is a residential tubular deadbolt in a cylinder x thumbturn function, so when a project spec calls for a stated ANSI/BHMA grade, the substitution moves to a graded peer with the same cylinder x thumbturn operation. The Accentra D111 is a Grade 1 single cylinder deadbolt with a 2-3/8 inch backset and a 1-3/8 to 1-3/4 inch door thickness range. The Dexter DB1000 single cylinder is Grade 1 over a 1-3/8 to 1-7/8 inch door range, and the Delaney LM Series is a Grade 1 single cylinder supplied less core for facilities keying to their own cylinders. All three keep the thumbturn inside, which is what the 8457 does; what changes is the decorative sandcast bronze trim.
7) Which deadbolt should be used instead of the Emtek 8457 on a door that needs a fire rating?
The Emtek 8457 is a residential sandcast bronze deadbolt. For an opening where the deadbolt has to carry a fire rating, the Hager 3215 is a single cylinder deadbolt with a 1 inch throw, a Schlage C keyway, a fire rating, and a 1-3/8 to 1-3/4 inch door thickness range; the Hager 3115 is a cylinder x thumbturn deadbolt with the same Schlage C keyway, fire rating, and door range. The Cal-Royal CRB800 is a heavy duty single cylinder deadbolt with a UL 3-hour fire rated latch. The Hager pair shares the 8457's Schlage C keyway, so an existing Schlage keying system carries over.
8) What deadbolt replaces the Emtek 8457 on a door thicker than 2 inches?
The Emtek 8457 covers 1-3/8 to 2 inch doors, with a standard build for 1-3/4 inch and an EMPowered version reaching 2-1/4 inches. For a thick door outside that range in a standard mechanical deadbolt, the Corbin Russwin DL3011 Grade 1 cylindrical deadlock is built for 1-3/4 to 2-1/4 inch doors. Note that the DL3011 is a cylinder x blank deadlock, so there is no inside thumbturn as there is on the 8457. Where the door is 1-3/4 inch flat, the Corbin Russwin DL3211 Grade 1 deadlock and the Design Hardware D1 Series Grade 1 double cylinder are both built to that single thickness.
9) Which deadbolt should a facility take instead of the Emtek 8457 when the keying has to run on interchangeable cores?
The Emtek 8457 comes with a Schlage C keyway as standard and a Weiser WR5 cylinder at no upcharge, both conventional cylinders that can be keyed alike or keyed to code. A facility standardized on interchangeable cores needs a body prepped for its own cores instead: the Arrow E61 is a Grade 2 single cylinder deadlock with SFIC prep less core over 1-3/8 to 1-3/4 inch doors, the Deltana CL200LAIC is a Grade 2 single deadbolt with interchangeable core and a 2-3/4 inch backset, and the Delaney LM Series is a Grade 1 single cylinder supplied less core.
10) Which single cylinder deadbolt matches the Emtek 8457 if a 2-3/4 inch backset is already drilled?
The Emtek 8457 can be ordered with a 2-3/4 inch backset latch when specified rather than the standard 2-3/8 inch, so an existing 2-3/4 inch prep is covered directly. Among comparable single cylinder units built to that backset, the Deltana CL200LA is a Grade 2 single deadbolt with a 2-3/4 inch backset, and the Deltana CL200LAIC is the same Grade 2 single deadbolt with an interchangeable core. Where the prep is 2-3/8 inch instead, the Accentra D111 is a Grade 1 single cylinder deadbolt built to a 2-3/8 inch backset.
11) What finishes does the Emtek 8457 sandcast bronze deadbolt come in?
Three: Flat Black Bronze (FB), Medium Bronze (MB), and Tumbled White Bronze (TWB). All three are offered in both the Schlage and the Weiser keyway, so you are not forced off a finish by your keying. These are cast bronze finishes from Emtek's Sandcast Bronze collection, so they will match other 8400 series sandcast trim on the same opening rather than the smooth plated finishes on Emtek's brass lines.
12) Does a strike plate come with the Emtek 8457 deadbolt or do I order it separately?
It is included. Every 8457 ships with a brass trim strike plus a heavy gauge steel understrike that sits behind it and takes the load into the jamb. Nothing else to buy for the strike side. You do still choose backset, keying, and door thickness on the order.
13) I am standardizing several entry doors, can I get all the Emtek 8457 deadbolts on one key?
Yes, keyed alike is a no-cost option on the order, and you can also give a key code to cut them into an existing system. On Schlage C that means matching an existing Schlage-keyed building; ordering the W version instead cuts them to Weiser WR5. Mixing keyways across the same key group will not work, so pick one keyway for the whole set of doors.
14) Can I use the Emtek 8457 as an auxiliary deadbolt above an existing knob or lever?
That is the normal use. It is a standalone tubular deadbolt, not interconnected with a handle, so it goes in its own 2-1/8 inch cross bore above the entry set. Match the backset of the deadbolt bore, not the knob bore, when you order 2-3/8 versus 2-3/4. If you want the deadbolt and lever tied together on one prep so the inside lever retracts both, that is an interconnected lock instead, like the Falcon H2101 entrance set with a single cylinder deadbolt.
15) Is the Baldwin Reserve deadbolt spacer or the BEST 8T tube a substitute for the Emtek 8457 deadbolt?
No. The Emtek 8457 is a complete single cylinder deadbolt with cylinder, housing, collar, thumbturn, rosette, hardened steel bolt, understrike, and brass trim strike. The Baldwin Reserve 8BR0618001 is a deadbolt spacer for a double cylinder application, and the BEST 8T is the T Series tubular deadbolt tube component. Those are pieces that go inside or behind a lock, not a lock a door can be finished with. If a full decorative bronze deadbolt is what the opening needs, the 8457 stands on its own; if the goal is a graded complete unit, the Accentra D111 Grade 1 single cylinder is the comparable to order.
16) Which deadbolt has an adjustable backset if the door prep does not match the Emtek 8457 backset choice?
The Emtek 8457 ships with a 2-3/8 inch backset latch as standard and a 2-3/4 inch backset when specified, so the backset is fixed at the time of order. Where the crew will not know the prep until they are on site, an adjustable-backset deadbolt covers both holes from one box. The Cal-Royal ED500 is a Grade 3 single cylinder deadbolt with an adjustable backset over 1-3/8 to 1-3/4 inch doors, the Falcon D111 is a Grade 1 deadbolt with adjustable backset, and the Brinks Raleigh and Mendocino single cylinder deadbolts both carry a 4-way adjustable backset.
17) What is a simpler single cylinder deadbolt than the Emtek 8457 for a rental unit that does not need decorative bronze trim?
The Emtek 8457 is a sandcast bronze deadbolt with a flap, built with a solid brass cylinder, housing, collar, thumbturn, and rosette for a rustic decorative opening. Where the door only needs a working keyed deadbolt, several plainer cylinder x thumbturn units cover it: the Dexter DB2000 is a Grade 2 single cylinder over 1-3/8 to 1-3/4 inch doors, the Arrow DBX61 is a Grade 2 single cylinder deadbolt, the Bravura 310B Elite is a Grade 2 traditional round deadbolt, and the Cal-Royal CB160 is a Grade 2 single cylinder with a tamper-resistant cylinder guard. All four keep the same keyed-outside, thumbturn-inside operation the 8457 uses.
18) Can the Emtek 8457 be swapped for an electronic or keypad deadbolt on the same door?
The Emtek 8457 is a mechanical, non-electronic deadbolt keyed on the outside with a thumbturn inside. Where an opening is moving to code or credential entry instead of keys, the Delaney KP400 is a Grade 2 electronic deadbolt with a programmable remote, the Dormakaba Saffire LX-D is an RFID electronic deadbolt with BLE and electronic lock override, and the Codelocks CL2210 is an electronic mortise deadbolt. These change how the door is opened rather than just the trim, so the credential plan and the decorative bronze look of the 8457 are the two things being traded against each other.
19) Does the Arrow 460 mortise strike or the Arrow E60 exit deadlock work as a replacement for the Emtek 8457?
Neither one does the same job. The Emtek 8457 is a keyed single cylinder tubular deadbolt with a thumbturn, and it ships with its own heavy gauge steel understrike and brass trim strike. The Arrow 460 is a mortise lock strike for latchbolt and deadbolt functions with a straight lip on 1-3/4 inch doors, which is strike hardware, not a lock. The Arrow E60 is a Grade 2 exit deadlock that is non-keyed, with a blank plate outside and a thumbturn inside over 1-3/8 to 1-3/4 inch doors, so there is no key entry from the outside. For a keyed exterior door the 8457 or another cylinder x thumbturn unit such as the Deltana CL200LM Grade 1 single cylinder is the right shape of product.
20) What deadbolt is used instead of the Emtek 8457 when a classroom security function is required?
The Emtek 8457 is a single cylinder deadbolt with a fixed thumbturn inside, which throws and retracts the bolt from the room side at all times. A classroom function keyed deadbolt is a different animal: the Falcon D111 is a Grade 1 heavy duty classroom deadbolt with adjustable backset, the Falcon D211 is a Grade 2 medium duty classroom function deadbolt with single cylinder operation, and the Hager 3118 is a Grade 1 classroom deadbolt with a Schlage C keyway and a 6-pin cylinder over 1-3/8 to 1-3/4 inch doors. The Hager 3118 shares the 8457's Schlage C keyway.
21) Which deadbolt gives an easier-to-grip thumbturn than the Emtek 8457 for an accessible unit?
The Emtek 8457 has a solid brass thumbturn matched to its sandcast bronze trim. Where the turn has to be easy to operate with limited hand strength, the Cal-Royal LSD is a Grade 3 single cylinder deadbolt with an ADA ergonomic thumbturn over 1-3/8 to 1-3/4 inch doors. It keeps the same cylinder x thumbturn arrangement as the 8457, with the difference being the shape of the inside turn piece rather than the way the lock works.
22) What is the alternative to the Emtek 8457 for a door that has only one side available or an existing half bore?
The Emtek 8457 uses a standard door prep with a 2-1/8 inch cross bore and a 1 inch edge bore, drilled through for a cylinder outside and a thumbturn inside. Where only one face of the door can take hardware, the Callan Model 205S is a Grade 3 one-sided half-bore deadbolt. For a door that is being secured from inside only, the Arrow E60 is a Grade 2 exit deadlock with a blank plate outside and a thumbturn inside over 1-3/8 to 1-3/4 inch doors. Both give a different bore condition than the 8457's full through-bore.
23) How does the Emtek 8457 compare to a mortise deadbolt for an existing mortise-prepped door?
The Emtek 8457 is a tubular deadbolt installed in a bored door prep with a 2-1/8 inch cross bore and 1 inch edge bore. A door already prepped for a mortise case will not take that prep. The Dormakaba D900 is a small case mortise dead bolt with a D cylinder, keyed different, in Schlage keyways, and the Dormakaba M1960 is an M1000 Series single cylinder deadbolt with cylinder and turn supplied with no trim. The Codelocks CL200 is a surface deadbolt with key override for a door where no bore or mortise pocket is being cut at all.
24) What is the difference between the Emtek 8457 and a plain builder-grade deadbolt like the Bravura 310B or Callan 200S?
Material and prep are the split. The 8457 is sandcast bronze with solid brass cylinder, housing, collar, thumbturn and rosette and a hinged flap over the keyway, keyed Schlage C or Weiser, on a fixed 2-3/8 or 2-3/4 backset you specify. The Bravura 310B Elite and the Callan 200S-G2 are Grade 2 cylinder x thumbturn deadbolts, plain round or square trim. If the opening needs a stated grade, those carry one; if it needs to look like the rest of a rustic bronze entry package, the 8457 does not have a substitute in that group.
