Emtek 8359-US26 – Frequently Asked Questions

1) What is the difference between a double cylinder deadbolt and a single cylinder one, and should I use the 8359?
The Knoxville 8359 is double cylinder, meaning it is keyed on both sides with no thumbturn. That is what you want when there is glass in or beside the door and a thumbturn could be reached through a broken pane. The tradeoff is that nobody can exit without a key, so many jurisdictions restrict double cylinder on a required egress door in a dwelling. If you need thumbturn egress inside, order a cylinder x thumbturn deadbolt instead, such as the Dexter DB1000 single cylinder.
2) Can I key the Emtek 8359 into my existing Schlage or Weiser keys?
Both keyways are offered. Standard is a Schlage C cylinder; adding a W to the front of the product code gets the Weiser WR5 cylinder at no upcharge, which can be keyed into an existing Weiser system. You also choose keyed alike or keyed different at ordering, and you can supply a key code if you are matching an existing system.
3) My door is 2 inches thick. Will this deadbolt still work?
Yes, up to 2 inches. The Knoxville 8359 covers 1-3/8 through 2 inch doors, but 1-3/4 inches is what ships by default, so enter your actual thickness on the order. Thicker than 2 inches is outside the range for this mechanical version.
4) What is a comparable double cylinder deadbolt to the Emtek 8359 Knoxville for a commercial opening that needs a Grade 1 rating?
The Emtek 8359 Knoxville is a double cylinder brass deadbolt built for residential use. Where a Grade 1 double cylinder deadbolt is required, the Design Hardware D1 Series double cylinder deadbolt is Grade 1, extra heavy duty, and specified for 1-3/4 inch doors, and the Dexter DB1000 double cylinder deadbolt is Grade 1 with a 1-3/8 to 1-7/8 inch door thickness range.
5) If a double cylinder deadbolt is not allowed on the egress door, what single cylinder version should be used instead?
The Emtek 8359 Knoxville is keyed on both sides. Where a thumbturn inside is required, single cylinder deadbolts with a cylinder x thumbturn function include the Dexter DB1000 (Grade 1, 1-3/8 to 1-7/8 inch doors), the Dexter DB2000 (Grade 2, 1-3/8 to 1-3/4 inch doors), and the Accentra D111 (Grade 1, 2-3/8 inch backset, 1-3/8 to 1-3/4 inch doors).
6) Is there a double cylinder deadbolt that matches the Emtek 8359 Knoxville door thickness range of 1-3/8 inch to 2 inch?
The Emtek 8359 Knoxville covers 1-3/8 inch to 2 inch doors as standard. Among other double cylinder deadbolts, the Deltana 7312KA2 lists the same 1-3/8 inch to 2 inch door thickness range and is a Grade 3 heavy duty KA2 unit, which is useful on thicker stile-and-rail or applied-panel doors.
7) Which deadbolts other than the Emtek 8359 Knoxville use a Schlage C keyway so they can go on the same key system?
The Emtek 8359 Knoxville ships with a Schlage C keyway as standard, with a Weiser WR5 cylinder available in place of it. Other deadbolts on the Schlage C keyway include the Hager 3214 double cylinder Grade 2 deadbolt and the Hager 3215 single cylinder Grade 2 deadbolt with a 1 inch throw, both rated for 1-3/8 to 1-3/4 inch doors, so a facility keyed to Schlage C can mix decorative and commercial trim on one system.
8) What deadbolt should be used instead of the Emtek 8359 Knoxville on a fire rated door?
The Emtek 8359 Knoxville is a residential brass deadbolt. Where a fire rating is called for, the Hager 3115 cylinder x thumbturn deadbolt and Hager 3118 Grade 1 classroom deadbolt are both fire rated for 1-3/8 to 1-3/4 inch doors, and the Cal-Royal CRB800 is a heavy duty single cylinder deadbolt with a UL 3-hour fire rated latch.
9) Do I need to specify handing for the Emtek Knoxville deadbolt?
No handing is required. The 8359 deadbolt is non-handed, so the same part works on a left or right hand door. What you do have to specify is backset (2-3/8 or 2-3/4 inch) and door thickness if it is not the standard 1-3/4 inches.
10) What finishes does the Emtek 8359 Knoxville 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). Every one of those is available with either the Schlage C or the Weiser WR5 cylinder, so you can match the rest of the Emtek brass collection on the opening without giving up your keyway.
11) Is the Emtek 8359 heavy enough for a commercial entry door?
It is a residential grade product. The cylinder, housing, collar, thumbturn and rosette are solid brass with a hardened steel bolt and heavy gauge steel understrike, which is solid for a home or a high end multi-family entry, but it is not a commercial graded deadbolt. For a commercial opening look at a Grade 1 double cylinder unit such as the Design Hardware D1 Series or the Delaney LU Series Grade 2 double cylinder.
12) What comes in the box with the Emtek Knoxville deadbolt?
A brass trim strike ships with every deadbolt, along with the heavy gauge steel understrike behind it. The bolt is hardened steel. You pick backset at ordering, and if your door is not 1-3/4 inches you enter the actual thickness so the right length parts are sent.
13) What is a comparable double cylinder deadbolt if I want something other than Emtek brass?
Among double cylinder units, the Baldwin Reserve Contemporary Round and Contemporary Square deadbolts are the closest decorative peers. If grade matters more than styling, the Dexter DB1000 double cylinder is Grade 1 for 1-3/8 to 1-7/8 inch doors and the Dexter DB2000 double cylinder is Grade 2 for 1-3/8 to 1-3/4 inch. Note the Emtek covers a wider 1-3/8 to 2 inch range than either Dexter.
14) Is the Emtek 8359 a tubular deadbolt or a mortise deadbolt?
Tubular. It drops into a bored 2-1/8 inch cross bore with a 1 inch edge bore, so it goes into a standard drilled door rather than a routed mortise pocket. If your door has a mortise pocket already, you would need a mortise deadlock instead, like the Dormakaba D900 small case mortise deadbolt.
15) What looks like a substitute for the Emtek 8359 Knoxville deadbolt but will not work in the same door prep?
The Emtek 8359 Knoxville is a tubular deadbolt using a 2-1/8 inch cross bore, 1 inch edge bore, and a 2-3/8 inch or 2-3/4 inch backset. Mortise-prepped products are not drop-in alternatives: the Dormakaba D900 is a small case mortise deadbolt and the Codelocks CL2210 is an electronic mortise deadbolt. Surface-applied units such as the Codelocks CL200 with key override also mount differently. The Arrow 460 is a mortise lock strike rather than a lock at all.
16) Is there a keyless alternative to the Emtek 8359 Knoxville double cylinder deadbolt?
The Emtek 8359 Knoxville is a keyed mechanical deadbolt with no electronic function. Keyless options include the Arrow E60, 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, and the Codelocks CL200 surface deadbolt with key override. For credential-based access, the Delaney KP400 is a Grade 2 electronic deadbolt with a programmable remote.
17) What other decorative double cylinder deadbolts compare to the Emtek 8359 Knoxville?
The Emtek 8359 Knoxville is an American Designer style solid brass double cylinder deadbolt offered in finishes including Oil Rubbed Bronze US10B, Satin Nickel US15, Polished Chrome US26, Polished Brass US3, Unlacquered Brass US3NL, Pewter US15A and French Antique US7. Comparable decorative double cylinder units include the Baldwin Estates 8011 contemporary 1-5/8 inch deadbolt and the Baldwin Reserve double cylinder deadbolt in contemporary round or contemporary square trim.
18) For a school or institution standardizing deadbolts, what should be specified instead of the Emtek 8359 Knoxville?
The Emtek 8359 Knoxville is a residential brass deadbolt with a double cylinder function. Institutional standards usually call for a classroom deadbolt: the Falcon D111 is Grade 1 heavy duty cylinder x thumbturn with an adjustable backset, the Falcon D211 is the Grade 2 medium duty equivalent, and the Corbin Russwin DL3011 is a Grade 1 cylindrical deadlock with a cylinder x blank configuration for 1-3/4 to 2-1/4 inch doors.
19) What deadbolt works if the backset is not known before ordering, unlike the Emtek 8359 Knoxville?
The Emtek 8359 Knoxville requires the backset to be specified as either 2-3/8 inch or 2-3/4 inch at order. Where the prep is unknown, the Brinks Raleigh and Brinks Mendocino single cylinder deadbolts use a 4-way adjustable backset, and the Cal-Royal ED500 is a Grade 3 single cylinder deadbolt with an adjustable backset for 1-3/8 to 1-3/4 inch doors.
20) Is there an alternative to the Emtek 8359 Knoxville that accepts an interchangeable core?
The Emtek 8359 Knoxville uses a Schlage C or Weiser WR5 cylinder. If the keying program is built on interchangeable cores, the Arrow E61 is a Grade 2 single cylinder deadlock with SFIC prep supplied less core for 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 less core deadbolt.
