Emtek 8112-US26 – Frequently Asked Questions
1) Will the Emtek 8112 sideplate lockset fit a 1-3/8 inch door, or is it 1-3/4 only?
Both. The 8112 Modern sideplate entry set covers doors from 1-3/8 to 1-3/4 inches thick, so it works on older interior slabs and standard exterior doors alike. There is a door thickness field on the order form, so state your actual slab thickness when you order.
2) Can the Emtek 8112 be installed on a door already bored for a standard knob?
Yes, if that door is bored 2-1/8 inches. The 8112 uses one standard 2-1/8 inch cross bore, which is the normal bore on residential doors, and the latch is adjustable for either a 2-3/8 or 2-3/4 inch backset. The long sideplate is what needs the extra room, since it spans 3-5/8 inches center to center between the knob or lever and the key cylinder, so you will be cutting new plate mortise and a hole for the cylinder above or below the existing bore.
3) What backset do I order for the Emtek 8112, 2-3/8 or 2-3/4 inch?
Measure from the door edge to the center of the bore. If that is 2-3/8 inches you take the standard latch; if the bore sits 2-3/4 inches in, specify the 2-3/4 backset when you order. Both are offered on the 8112 and backset is a required selection, so it is not something you can leave blank and sort out on site.
4) Do I have to specify handing when ordering an Emtek 8112 sideplate lockset?
Handing is a required choice, right hand or left hand. It genuinely matters on levers, which have to point down toward the latch side, and on a sideplate set the plate itself is oriented to the door. Stand outside the door: if the hinges are on your right it is right hand, hinges on the left is left hand.
5) Is the Emtek 8112 single cylinder or double cylinder, and is that alright for a door with glass?
Single cylinder. The 8112 is an entry function set keyed on the outside only, with a thumbturn or interior trim inside, so nobody needs a key to get out. That is the usual choice for a front door and it is the one that keeps you clear of egress problems. If you specifically want a key required from both sides, the 8112 is not it, and something like the Omnia D12036AC double cylinder deadbolt lever lockset is the double cylinder alternative.
6) What comes in the box with the Emtek 8112, and do I need to buy a deadbolt separately?
The 8112 ships as a complete set: your chosen knob or lever, the latch, and the strike plate, plus the exterior sideplate with the keyed cylinder. It is a keyed entry set in itself, so a separate deadbolt is optional rather than required. You still pick the interior knob or lever style, the finish, handing, backset and keying at order time, since those are all required selections.
7) Can I key several Emtek 8112 locksets alike so one key runs the whole house?
Yes. Keying is a required selection with keyed alike or keyed different, and there is a keying to code field if the property is already on an existing key code and you need these cut to match it. Order all the openings on the same purchase and put the same code or the keyed alike selection on each so they arrive matched rather than needing a locksmith after the fact.
8) What is the closest single cylinder sideplate lockset to the Emtek 8112 if the Emtek finish or trim style does not work for the opening?
The Omnia D12036A is the nearest equivalent: a single cylinder deadbolt lever lockset in solid brass with the same key-outside, lever-inside arrangement as the Emtek 8112, which is a single cylinder keyed entry lockset in brass. The practical difference to check before ordering is plate spacing - the 8112 uses 3-5/8 inch center-to-center, so if the door is already prepped for the Omnia family, confirm the bore spacing matches before swapping either direction.
9) The door has glass beside the lock and the code official wants a key on both sides - what sideplate lockset should be used instead of the Emtek 8112?
Use the Omnia D12036AC, which is a double cylinder deadbolt lever lockset in solid brass with a sideplate design. The Emtek 8112 is single cylinder, meaning it takes a key outside and a thumbturn or interior trim inside; the D12036AC is keyed from both sides, which is what a glass-adjacent opening usually calls for. Confirm the requirement with the authority having jurisdiction, since double cylinder hardware is restricted on some egress doors.
10) The existing sideplates on the doors are bored 5-1/2 inch apart - will an Emtek 8112 drop into that prep?
Not without rework. The Emtek 8112 is a 3-5/8 inch center-to-center sideplate lockset, so it will not line up with a 5-1/2 inch spread. The Omnia D12036PD is listed at 5-1/2 inch center to center, and the Omnia D12036A and D12036AC come from that same sideplate family, so a door already prepped at the wider spacing is better served there. When standardizing a building, decide the center-to-center dimension first and let the function - single cylinder, double cylinder, or dummy - follow per opening.
11) Is the Emtek 8112 sideplate lockset rated for commercial traffic?
It is a residential set. The 8112 is a brass tubular lockset built for houses and residential units, so for a school corridor, a retail entry, or anything taking commercial cycle counts you want a cylindrical or mortise commercial lock instead. For apartment unit entry doors and single family front doors it is squarely in its lane.
12) Can I put a knob on the inside of an Emtek 8112 instead of a lever?
Yes. The inside trim is your pick from Emtek's full brass knob and lever range, so you can run a lever where you want ADA-friendly operation and a knob elsewhere, including crystal options like the Windsor and Modern Disc, knurled options like the Ace Knurled, and modern bars such as the T-Bar and R-Bar. Handing still has to be given either way.
13) Will the round corner latch on the Emtek 8112 drop into my existing latch mortise?
The latch faceplate comes round corner or square corner, so match whichever your door is already routed for and you avoid recutting the edge. Round corner drops into a router-cut mortise; square corner suits a chiselled square pocket.
14) What is the difference between the Emtek 8112 sideplate lockset and an Omnia sideplate deadbolt lever set?
The 8112 is a keyed entry lockset: latch, strike and a single cylinder in one 3-5/8 inch center to center sideplate, so the handle and the key work the same latch. The Omnia D12036A is a single cylinder deadbolt lever lockset, and the D12036PD is the dummy version with plates on a 5-1/2 inch center to center for a door that does not latch at all. Pick by what the opening has to do: latching entry, deadbolt, or fixed pull.
15) What matches the look of a keyed sideplate lockset on a door that does not need to latch, such as an inactive leaf or a closet?
The Omnia D12036PD is a solid brass dummy deadbolt lever lockset with plates at 5-1/2 inch center to center, a double dummy function - it mounts through the door for appearance and pull only, with no latch and no cylinder. The Emtek 8112 is a keyed entry lockset with a tubular latch, so it is the wrong choice for an opening that is only being pulled. Pair the dummy on the inactive leaf with a keyed unit on the active leaf when the two doors need to read the same.
16) What finishes does the Emtek 8112 Modern keyed sideplate lockset come in?
Six: Oil Rubbed Bronze (US10B), Satin Nickel (US15), Flat Black (US19), Polished Chrome (US26), Unlacquered Brass (US3NL) and Satin Brass (US4). Worth knowing on a fleet of doors, Unlacquered Brass is a living finish and will darken with handling, so it will not stay matched to a lacquered brass piece already on the building.
17) Is the Emtek 8112 solid brass or plated?
Brass through the substrate, not a plated zinc body. That matters on an exterior door in a coastal or wet climate, and it is why the Unlacquered Brass option can be left to patina rather than flaking.
18) Which sideplate lockset gives the widest choice of knob and lever trim for a residential remodel?
The Emtek 8112 is ordered with the inside knob or lever style specified separately, spanning contemporary shapes like the Stuttgart and Helios levers through crystal and marble knobs, in six finishes from Oil Rubbed Bronze US10B to Unlacquered Brass US3NL. The Omnia D12036A and D12036AC are solid brass lever locksets, so the trim decision there is a lever rather than a knob. If the design calls for a crystal or knurled knob on a keyed sideplate, the 8112 is the one that supports it.
