Emtek 4310-US15 – Frequently Asked Questions

1) Will the Emtek 4310 Knoxville handleset fit a 2-1/8 inch bored door prep?
Yes. The Knoxville handleset uses the standard 2-1/8 inch cross bore with 5-1/2 inch center-to-center spacing between the deadbolt and the knob or lever bore. If your door is already prepped for a common tubular handleset at that 5-1/2 inch CTC, it drops in without redrilling. Door thickness range is 1-3/8 to 2 inches, which covers a standard 1-3/4 inch entry door and thicker custom slabs.
2) Do I have to specify handing when ordering an Emtek Knoxville 4310 handleset?
Handing is required, left or right, on every order. Even where the exterior grip is symmetrical, the inside trim drives it: if you pick a lever for the interior, or specify an interconnect device, the part is built handed. Determine hand from outside the door, standing on the exterior side, and note which side the hinges are on before you order.
3) What comes in the box with an Emtek Knoxville entrance handleset, and what do I still have to order?
The Knoxville is sold as a complete set with the latch and strike plate included. What you do have to choose is the interior trim: a brass knob or lever is a required selection, not an accessory, with options from plain Round and Egg knobs through Cortina, Milano and Rustic levers to crystal knobs like Windsor and Georgetown. You also pick handing, backset, finish, keyway, and keying. A split finish (different inside than out) can be requested.
4) The Emtek 4310 fits doors up to 2 inches thick - what handleset works on a 2-1/4 inch door?
The Emtek 4310 Knoxville is rated for 1-3/8 inch to 2 inch doors, so a thicker slab needs a different set. The Weslock 1411 Traditionale Colonial single cylinder handleset with Eleganti knob covers 1-3/4 inch to 2-1/4 inch. On the electronic side, the Yale Assure BYRD226NRRX standalone touchscreen deadbolt with Ridgefield handleset and the BYRD226CBARX Wi-Fi and Bluetooth version both cover 1-3/4 inch to 2-1/4 inch as well.
5) What is the closest solid brass alternative to the Emtek 4310 Knoxville entrance handleset?
The Emtek 4310 Knoxville is a single cylinder entry handleset built in brass with a tubular lock, and the Deltana Hanover 803871B, St. Ann 815871, and Kingston 825871 are all solid brass entry handlesets in the same footprint. The Deltana Montego 810871 covers the same 1-3/8 inch to 2 inch door thickness range the 4310 does. Choose on trim style and finish, since all four are brass entry handlesets for a standard residential entry door.
6) Is there a graded handleset to use instead of the Emtek 4310 Knoxville on a rental or multi-family entry?
The Emtek 4310 Knoxville is a residential brass handleset. Where a graded set is wanted for turnover units, the Schlage Residential F60 Addison single cylinder keyed entry handleset with Accent lever is Grade 2 and fits 1-3/8 inch to 1-3/4 inch doors, and the Master Lock HDLBA0615/4D single cylinder deadbolt handleset is also Grade 2. The Kwikset 687AMD Amador and 687BW Belleview single cylinder handlesets are Grade 3 and fit 1-3/4 inch doors.
7) Which handlesets look like the Emtek 4310 Knoxville but are not a drop-in replacement?
The Emtek 4310 Knoxville is a tubular single cylinder entry handleset supplied as a complete set with latch and strike. Two families in the same style are built differently. The Baldwin Estates 6542 Tremont single cylinder and 6542 double cylinder are mortise entry trim for 1-3/4 inch doors, which is a mortise pocket rather than the 2-1/8 inch cross bore the 4310 uses. The Kwikset 687AMD Amador and 687BW Belleview are sold as exterior only, so no interior trim comes with them, where the 4310 ships as a complete set with the inside knob or lever specified.
8) Can I key the Emtek 4310 into an existing Kwikset SmartKey system, or do I need a different handleset?
The Emtek 4310 Knoxville ships with a Schlage C keyway and can be ordered with a Weiser WR5 cylinder at no upcharge to key into an existing Weiser system. It does not come in SmartKey. For a SmartKey building, the Kwikset 687AMD Amador is offered in SmartKey as 687AMD SMT and in an SC1 keyway SmartKey version as 687AMD SMC, and the Kwikset 687BW Belleview is a SmartKey set as well, all Grade 3 for 1-3/4 inch doors.
9) Can I order several Emtek Knoxville handlesets keyed alike for a rental property?
Yes. Keyed alike is a selectable keying option, so a set of front doors can run on one key. Keyed different is the other choice, and you can also key to an existing code if you already have a master system in place. Standard cylinder is Schlage C; if your property is already on Weiser, order the WR5 keyway instead and it will key into that system.
10) Single cylinder or double cylinder handleset for a door with glass next to it?
The 4310 Knoxville is a single cylinder entry set: key outside, thumbturn inside. That is the right choice for a solid door, and it is what most codes want on an egress door since nobody needs a key to get out. If there is glass within reach of the interior thumbturn, a double cylinder set (key both sides) is what people reach for, though it trades away that keyless exit. Baldwin's Estates 6542 Tremont is offered both ways, single cylinder and double cylinder, if you need the double cylinder route.
11) Is the Emtek Knoxville handleset tubular or mortise, and does that change my door prep?
Tubular. The 4310 Knoxville works off standard bored holes, a 2-1/8 inch cross bore at 5-1/2 inch center-to-center, so it goes on a door prepped like any bored lockset. A mortise handleset needs a rectangular pocket routed into the door edge and is a different prep entirely. If your existing door has round bores, tubular is what you want; converting to mortise means machining the slab.
12) What finishes does the Emtek Knoxville 4310 handleset come in, and will they match my other Emtek brass hardware?
Seven finishes: Oil Rubbed Bronze (US10B), Satin Nickel (US15), Pewter (US15A), Polished Chrome (US26), Polished Brass Lifetime (US3), Unlacquered Brass (US3NL), and French Antique (US7). The set is solid brass, part of Emtek's Brass collection, so the finishes carry across other Emtek brass knobs and levers on the same job. Unlacquered brass is the one to think about on a fleet: it has no clear coat and will patina with handling, so it will not stay matched to a lacquered set over time.
13) Is the Emtek 4310 Knoxville handleset suitable for a commercial entrance or apartment building corridor?
It is catalogued as a residential product, so a house, condo, or townhome front door is where it belongs. For a high-traffic commercial opening or a multi-family corridor you want a Grade 1 or Grade 2 rated set instead. Among handlesets we carry, the Master Lock HDLB Series HDLBA0615/4D is Grade 2, as is the Schlage Residential F60 Addison with Accent lever.
14) I want a keypad or app-controlled entry instead of the keyed Emtek 4310 - what handleset does that?
The Emtek 4310 Knoxville is a mechanical, non-electronic handleset keyed to a Schlage C or Weiser WR5 cylinder. For electronic entry in a handleset form, the Kwikset 815SCEHFL-CP913CNT San Clemente handleset pairs a Halifax lever interior with a contemporary SmartCode keypad electronic deadbolt on 1-3/4 inch doors. The Yale Assure BYRD226CBARX adds Wi-Fi and Bluetooth with the Ridgefield handleset, and the BYRD256 CBARX is a key free touchscreen deadbolt with the Ridgefield passage handleset.
15) What is a simpler single cylinder handleset than the Emtek 4310 Knoxville for the same door?
The Emtek 4310 Knoxville is a brass entry handleset ordered with a chosen inside knob or lever, handing, and backset. Where a fixed, preconfigured set is easier to specify, the Weslock 2810 Hillcrest single cylinder handleset with Hudson knob covers 1-3/8 inch to 2 inch doors, the same range the 4310 fits, and the Pamex FS7P31 Lexington single cylinder handleset comes in a satin nickel finish for 1-3/8 inch to 1-3/4 inch doors. The Baldwin Wesley handleset comes paired with either the Alcott knob as 180WYHXATK or the Carnaby knob as 180WYHXCYK in entrance function.
16) I need a keyed deadbolt with an interconnected passage lever rather than the Emtek 4310 handleset - what covers that?
The Emtek 4310 Knoxville is a single cylinder entry handleset, with handing required if an interconnect device is specified. Where an interconnected lock rather than a handleset grip is wanted, the Schlage Residential JI18/19 interconnected passage lock with keyed deadbolt and Torino lever in satin stainless steel is Grade 2 passage function for 1-3/8 inch to 1-3/4 inch doors. That gives a lever and separate keyed deadbolt in one trim instead of the gripped exterior plate the 4310 carries.
17) I am doing a front door and a matching side door that does not need a key. What Emtek-style options pair with a keyed handleset?
The Knoxville 4310 is a keyed entry set, so it locks. For a companion door that only needs to look the same without locking, a dummy handleset is the piece to ask for. In our range the Weslock 6695 Belmont with Impresa knob and the Weslock 2815 Hillcrest with New Heaven lever are both dummy function, and both cover 1-3/8 to 2 inch doors, the same thickness range as the Knoxville. The Schlage Residential JE285 Barcelona with Seville lever is a non-keyed entry handleset if you want a working latch without a cylinder.
