Emtek 8357-FB – Frequently Asked Questions
1) Will the Emtek 8357 double cylinder deadbolt fit a 1-3/8 inch door?
Yes. The 8357 sandcast bronze deadbolt covers 1-3/8 inch through 2 inch doors, so an older 1-3/8 inch entry door and a standard 1-3/4 inch one both work. Standard build ships set up for 1-3/4 inches, and a thin door gets an extension collar to take up the difference. If your door is thicker than 1-3/4 inches, call it out on the order (there's a Door Thickness field for exactly that) so the correct spindle and collar go in the box.
2) Does the Emtek 8357 deadbolt drop into an existing bored door prep?
It uses standard door prep: 2-1/8 inch cross bore, 1 inch edge bore, and either a 2-3/8 or 2-3/4 inch backset. That is the same prep almost every residential tubular deadbolt uses, so on a door already bored for a deadbolt it goes straight in. Measure from the door edge to the center of the existing hole first, 2-3/8 or 2-3/4 inches, and pick that backset on the order. Get the backset wrong and the bolt won't line up with the hole.
3) What's the difference between a double cylinder deadbolt and a single cylinder, and which do I want on a door with glass?
The 8357 is double cylinder, meaning it takes a key on both sides instead of a thumbturn inside. That's what you use on a door with glass beside it or a glass panel in it, where someone could break the glass, reach through, and turn an inside thumbturn. The tradeoff: nobody exits without a key, so many jurisdictions restrict double cylinder on a required egress door in occupied space. Check your local code before you spec it on a rental or commercial opening.
4) Can the Emtek 8357 be keyed to match my existing Schlage keys?
Standard cylinder is a Schlage C keyway, so it keys into an existing Schlage C system. If your building runs Weiser, order the WR5 keyway version instead and it keys into that system at no cylinder upcharge. Keying is set at order time, either keyed different or keyed alike across a group, and there's a field to give an existing key code so the new bolt matches what your tenants already carry.
5) Is the Emtek 8357 deadbolt rated for a commercial or multifamily entry door?
It's a residential deadbolt. Emtek classes the 8357 as residential tubular hardware, and the sandcast bronze line is decorative trim for homes and rustic-styled openings. For a commercial opening or a high-traffic multifamily entry, look at a graded commercial deadbolt instead: the Design Hardware D1 Series is a Grade 1 double cylinder for 1-3/4 inch doors, and the Hager 3214 is a Grade 2 double cylinder covering 1-3/8 to 1-3/4 inch doors with a Schlage C keyway, so it keeps the same key system you already run.
6) My door is thicker than 2 inches. Will the Emtek 8357 work?
Not past 2 inches. The 8357 covers 1-3/8 to 2 inch doors. For a thicker slab, the Corbin Russwin DL3011 is a Grade 1 cylindrical deadlock rated to 2-1/4 inch doors, and the Deltana 7312KA2 is a double cylinder covering 1-3/8 to 2 inches if you want to stay at the top of that same range in a keyed-both-sides bolt.
7) What is a double cylinder deadbolt equivalent to the Emtek 8357 sandcast bronze with a Grade 1 rating?
The Emtek 8357 with flap is a double cylinder tubular deadbolt in sandcast bronze, built for residential openings with a solid brass cylinder, housing, collar and rosette and a hardened steel bolt. If the opening needs an ANSI/BHMA Grade 1 double cylinder instead, the Design Hardware D1 Series is a Grade 1 double cylinder deadbolt rated extra heavy duty for 1-3/4 inch doors, and the Dexter DB1000 Series double cylinder is Grade 1 for 1-3/8 to 1-7/8 inch doors. Both trade the sandcast bronze decorative treatment for a graded commercial body.
8) I need a double cylinder deadbolt on a door thicker than 2 inches - what works?
The Emtek 8357 sandcast bronze deadbolt covers a door thickness of 1-3/8 to 2 inches, with 1-3/4 inch as standard. For a thicker leaf, the Corbin Russwin DL3011 cylindrical deadlock covers 1-3/4 to 2-1/4 inch doors. It is a Grade 1 deadbolt in a cylinder by blank configuration rather than keyed on both faces, so confirm the outside trim you need before substituting.
9) What is the difference between the Emtek 8357 double cylinder and a single cylinder deadbolt like the Dexter DB2000?
The Emtek 8357 is keyed on both sides - there is no thumbturn, so the door cannot be opened from inside without a key. The Dexter DB2000 Series single cylinder is a cylinder by thumbturn deadbolt, Grade 2, for 1-3/8 to 1-3/4 inch doors, and the Accentra D111 is a Grade 1 cylinder by thumbturn for 1-3/8 to 1-3/4 inch doors. Double cylinder is chosen for openings with glass beside the lock; egress codes in many jurisdictions restrict key-both-sides on required exits, so verify the opening before ordering either way.
10) Which double cylinder deadbolts use the same Schlage C keyway as the Emtek 8357 so they can be keyed alike?
The Emtek 8357 ships standard with a Schlage C keyway, with Weiser WR5 available at no cylinder upcharge. Among other deadbolts on Schlage C, the Hager 3214 is a Grade 2 double cylinder deadbolt with a Schlage C keyway for 1-3/8 to 1-3/4 inch doors. On the single cylinder side, the Hager 3115 is Schlage C cylinder by thumbturn and the Hager 3118 is a Grade 1 classroom deadbolt on Schlage C with a 6-pin cylinder, so a building can be keyed on one system across decorative and utility openings.
11) Does the Emtek 8357 work on a fire rated opening?
The Emtek 8357 is a residential sandcast bronze deadbolt. For an opening carrying a fire label, the Hager 3215 single cylinder with 1 inch throw, the Hager 3214 double cylinder and the Hager 3115 cylinder by thumbturn all carry a fire rating and cover 1-3/8 to 1-3/4 inch doors, and the Cal-Royal CRB800 is a Grade 1 heavy duty single cylinder deadbolt with a UL 3-hour fire rated latch.
12) Which of these deadbolt-named parts are not substitutes for the Emtek 8357?
The Emtek 8357 is a complete tubular deadbolt with cylinder, bolt, understrike and brass trim strike. Several items carry deadbolt in the name but are not a lock you can hang on the door in its place: the Arrow 460 is a mortise lock strike for latchbolt and deadbolt functions, the Baldwin Reserve 8BR0618001 is a deadbolt spacer, and the BEST 8T is a T Series tubular deadbolt tube component. The Arrow E60 is a Grade 2 exit deadlock that is non-keyed, blank plate by thumbturn, so it gives no key access from outside at all.
13) Is the Emtek 8357 deadbolt handed? Do I need to know which way my door swings?
No handing. The 8357 installs the same on a left hand or right hand door, so you don't need to determine swing before ordering. That also means one part number covers every door in a building regardless of how each one hangs.
14) What finishes does the Emtek 8357 sandcast bronze deadbolt come in?
Three sandcast bronze finishes: Flat Black Bronze (FB), Medium Bronze (MB), and Tumbled White Bronze (TWB). These are living finishes on cast bronze, not plated brass, so they read as rustic hardware and will patina with handling. Each is available with either the Schlage C or the Weiser WR5 cylinder, so pick the finish to match your other Emtek sandcast trim and the keyway to match your building's system.
15) Do I need to buy a strike plate separately with the Emtek 8357?
No, the strike comes in the box. Every 8357 ships with a brass trim strike plus a heavy gauge steel understrike that goes behind it into the jamb, which is what actually carries the load in a kick-in. Bolt is hardened steel; cylinder, housing, collar and rosette are solid brass. What you may still need is a longer set of jamb screws into the framing, since that is what makes the understrike worth having.
16) What else could I use if I want a double cylinder deadbolt but not a bronze rustic look?
Same function, different styling: the Baldwin Reserve Double Cylinder Contemporary Square and Contemporary Round deadbolts give you a clean modern rose, and the Baldwin Estates 8011 is a 1-5/8 inch contemporary double cylinder. On the value side, the Callan 210S is a Grade 3 double cylinder and the Delaney LU Series is a Grade 2 double cylinder in stainless steel (US32D). All are key-both-sides like the 8357, so the door-with-glass reasoning carries over.
17) What do I have to specify when ordering an Emtek 8357 deadbolt?
Four decisions. Keyway: Schlage C standard, or Weiser WR5 if you're matching an existing Weiser system. Finish: Flat Black Bronze, Medium Bronze, or Tumbled White Bronze. Backset: 2-3/8 or 2-3/4 inches, measured from door edge to the center of the bore. Keying: keyed different, or keyed alike across a group, with an optional field for an existing key code. Door thickness only needs calling out if the door is over 1-3/4 inches.
18) Can I key the Emtek 8357 alike with my other deadbolts across a property?
Yes, keyed alike is a keying option at order, and with a key code supplied the bolts can be cut to a system you already run. The practical limit is keyway: every lock in the group has to share one, either Schlage C or Weiser WR5. If you're standardizing a mixed property, note that the Hager 3115, 3118, 3214 and 3215 deadbolts also run Schlage C, so a commercial door can carry the same key as an Emtek bronze bolt on the front entry.
19) I want the same bronze look but with a thumbturn inside instead of a second key. What's the difference?
The 8357 is the double cylinder version, keyed on both sides. If you want a thumbturn on the interior, that's the single cylinder build of the same deadbolt, and it's the one that ships with the extension collar for thin doors. Function is the only difference in operation: same tubular chassis, same standard prep, same 2-3/8 or 2-3/4 inch backset, same sandcast bronze finishes. Go double cylinder only where glass is within reach of the lock.
20) Is there a simpler double cylinder deadbolt than the Emtek 8357 for a rental unit?
The Emtek 8357 is a sandcast bronze deadbolt with a flap, solid brass trim and a choice of Schlage C or Weiser WR5 keyway. Where the decorative bronze body is not needed, the Callan Model 210S is a Grade 3 double cylinder deadbolt, the Delaney LU Series is a Grade 2 double cylinder in stainless steel US32D finish, and the Deltana 7312KA2 is a Grade 3 double cylinder covering 1-3/8 to 2 inch doors - the same thickness range the 8357 covers.
21) What decorative double cylinder deadbolts are comparable to the Emtek 8357 sandcast bronze?
The Emtek 8357 is a rustic sandcast bronze deadbolt with a flap over the exterior cylinder, offered in Flat Black Bronze, Medium Bronze and Tumbled White Bronze. In the same decorative-brand tier, the Baldwin Estate 8011 is a contemporary 1-5/8 inch double cylinder deadbolt, and the Baldwin Reserve line offers double cylinder deadbolts in contemporary round and contemporary square trim. Those Baldwin trims are clean-lined contemporary shapes rather than the cast, textured bronze look of the 8357.
22) Can I use an electronic deadbolt in place of the Emtek 8357?
The Emtek 8357 is a mechanical, non-electronic deadbolt keyed on both faces. If keypad or credential access is the goal, the Delaney KP400 is a Grade 2 electronic deadbolt with a programmable remote, the Codelocks CL2210 is an electronic mortise deadbolt, and the Dormakaba Saffire LX-D is an RFID electronic deadbolt with BLE and electronic lock override. All three change the door prep and the credential model, so they are a redesign of the opening rather than a drop-in for a keyed bronze deadbolt.
23) I need a deadbolt that takes an interchangeable core instead of the Emtek 8357 Schlage C cylinder.
The Emtek 8357 comes with a fixed Schlage C cylinder, or Weiser WR5 by substitution. For a small format interchangeable core program, the Arrow E61 26D IC is a Grade 2 single cylinder deadlock with SFIC prep less core for 1-3/8 to 1-3/4 inch doors, the Deltana CL200LAIC is a Grade 2 single cylinder interchangeable core deadbolt with a 2-3/4 inch backset, and the Delaney LM Series is a Grade 1 single cylinder less core deadbolt in US26D. All three are single cylinder, so a keyed-both-sides opening needs a different selection.
24) What deadbolt should I use if the backset on my door will not match the Emtek 8357?
The Emtek 8357 ships with a 2-3/8 inch backset latch as standard and a 2-3/4 inch backset by specification, so both common preps are covered. Where a bore falls outside that or is unknown in the field, the Brinks Raleigh Series and Brinks Mendocino Series single cylinder deadbolts both use a 4 way adjustable backset, and the Cal-Royal ED500 is a Grade 3 single cylinder with adjustable backset for 1-3/8 to 1-3/4 inch doors. The Falcon D111 is a Grade 1 classroom deadbolt with adjustable backset for heavier duty openings.
25) Is a mortise deadbolt an alternative to the Emtek 8357 tubular deadbolt?
The Emtek 8357 is a tubular deadbolt using standard door prep - a 2-1/8 inch cross bore and 1 inch edge bore. A mortise deadlock needs a pocket cut into the door edge instead. The Dormakaba D900 small case mortise deadbolt is a cylinder by thumbturn keyed different on SC keyways, and the International Door Closers DH-1821 is a hook bolt deadlock with a flat faceplate, a configuration used on sliding and narrow stile openings. Neither drops into a bored door without new prep.
26) What is an ADA-friendly alternative to the Emtek 8357 for an inside thumbturn?
The Emtek 8357 is keyed on both sides and has no thumbturn, so there is no inside turn piece to grip. Where an easy-operation inside turn is required, 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. The Callan Model 205S is a one-sided half-bore deadbolt, Grade 3, for openings where no outside key access is wanted at all.
