Emtek 8080 Quincy 3-5/8" C-to-C Keyed Sideplate Lockset, Passage/Single Keyed - Brass Tubular

Both. The 8080 Quincy keyed sideplate set covers 1-3/8 inch to 1-3/4 inch doors, which is the full range of standard residential doors. It drops into one standard 2-1/8 inch cross bore, so if the door is already prepped for a common bored knob or lever set, the hole is right. There is a door thickness field on the order so you can state the actual door you are working with.

Yes, and it is a required selection. The Quincy 8080 latch is available for either a 2-3/8 inch or a 2-3/4 inch backset, the two backsets used on North American doors. Measure from the door edge to the center of the 2-1/8 inch bore: 2-3/8 is typical on residential interior and many entry doors, 2-3/4 shows up on heavier and older entry doors. The standard latch shipped is the 2-3/8; specify 2-3/4 if that is what your door is bored for.

Handing is required if you choose a lever. Levers have to be pulled down toward the correct side, so the order asks for right hand or left hand. Knobs are symmetrical and do not care. Stand on the outside of the door (the keyed side): if the hinges are on your right, it is right hand; hinges on the left, left hand.

Single cylinder. The Quincy 8080 is keyed from the outside only, with a thumbturn or interior trim on the inside, and it cannot be converted to key both sides. If you need a key on the interior face as well, that is a double cylinder product, for example the Omnia D12036AC, which we list with a double cylinder function.

Yes. The 8080 Quincy can be ordered keyed alike across multiple sets, or keyed different if each opening needs its own key, and both are free options at order time. There is also a key-to-code field, so if the building already runs on an existing key code you can supply it and have the cylinders cut to match rather than rekeying on site. This is the practical route for a property manager standardizing a unit or a small portfolio.

That is the spacing from the center of the knob or lever spindle to the center of the key cylinder on the sideplate. On the Quincy it is 3-5/8 inches, which is a compact plate compared with the longer sideplate sets, and it matters in two places: the plate needs enough flat door face and stile to sit on, and if you are replacing an existing sideplate lock you want the same center-to-center so you are not looking at old screw holes or a second bore in the wrong spot. Emtek's own longer sideplate sets and the Omnia D12036PD at 5-1/2 inch center-to-center are on a different spacing.

It is a residential entry product. Solid brass tubular construction, a bored lockset rather than a mortise lock, and Emtek lists it as residential. For a house, a condo unit door, a rental, or an interior entry it is the right class of hardware. For a commercial opening with high traffic or a fire-rated door assembly, you want a Grade 1 or Grade 2 commercial lockset instead, not a residential brass sideplate set.

It depends on two numbers on your existing door, both of which you can measure in a minute. The 8080 needs a 2-1/8 inch cross bore at either a 2-3/8 or 2-3/4 inch backset, and its cylinder sits 3-5/8 inches from the spindle center. If the old lock ran on the same 2-1/8 inch bore and one of those two backsets, the latch and knob go straight in. If the old plate had a different cylinder spacing, the sideplate will not cover the old cylinder hole, and that is the thing that catches people out on a swap, so check the center-to-center before you order.

The Omnia D12036A is a single cylinder deadbolt lever lockset in solid brass with a sideplate design, which puts it on the same footing as the Emtek 8080 Quincy: the 8080 is a keyed entry sideplate lockset with a single cylinder keyed function, built in brass with a tubular lock type. Both key from the outside and operate free from the inside without a key, so either one suits a front or side entry door where the exit side must stay unlocked to the hand. The Emtek 8080 measures 3-5/8 inch center to center between the knob or lever and the keyed cylinder, and its inside trim is chosen from the Emtek knob and lever range with handing specified for levers.

Use the Omnia D12036AC, a double cylinder deadbolt lever lockset in solid brass with a sideplate design. Its function is double cylinder, meaning a key operates the bolt from both faces of the door, which is the arrangement specified when breakable glass sits within reach of the inside trim. The Emtek 8080 Quincy is a single cylinder keyed entry lockset, so it turns from the inside without a key and does not meet that condition. Note that double cylinder hardware requires a key to exit and is restricted by egress code in many occupancies, so confirm the requirement with the authority having jurisdiction before ordering.

A sideplate set puts the key cylinder and the knob or lever on one continuous brass plate, so the entry function and the lock read as a single piece of hardware on the door face at 3-5/8 inch spacing. A conventional setup uses a bored knob or lever in one hole and a separate deadbolt bored above it, with two independent pieces of trim. The sideplate is the choice when you want the unbroken look on an entry door; the separate deadbolt route is the choice when you want to add a deadbolt to an opening that is already bored for a plain knob set, or when the two holes on the door are already spaced for it.

Eight: Oil Rubbed Bronze (US10B), Satin Nickel (US15), Pewter (US15A), Flat Black (US19), Polished Chrome (US26), Polished Brass Lifetime (US3), Unlacquered Brass (US3NL), and French Antique (US7). If you are matching existing openings, the two brass options behave differently over time: the Lifetime polished brass holds its finish, while the unlacquered brass is meant to patina with handling, so mixing the two across a set of doors will not stay matched.

Any of Emtek's brass knob and lever designs will go on it, and there are 89 to choose from on the inside trim selection, running from plain Round and Egg knobs through the Cortina, Milano and Turino levers to crystal knobs like Windsor and Bristol and the marble-topped L-Bar and T-Bar options. It is a required choice, so the design gets specified with the order rather than swapped later. Remember that any lever choice also makes handing mandatory.

For a non-locking opening you want a dummy or passage version rather than the keyed 8080, since the keyed set carries a cylinder you would not use. Omnia makes a solid brass dummy deadbolt lever lockset with plates, the D12036PD, on 5-1/2 inch center-to-center spacing, which gives you the sideplate appearance with no working lock. Note the spacing is different from the Quincy's 3-5/8 inches, so the two will not read as identical hardware if they sit side by side.

The Omnia D12036PD is a solid brass dummy deadbolt lever lockset with plates, function double dummy, at 5-1/2 inch center to center. A double dummy is surface mounted trim with no latch and no cylinder, so it gives a pull on both faces of an inactive leaf while carrying the same sideplate appearance. The Emtek 8080 Quincy is a working keyed entry lockset with a single cylinder and a latch, and it is not the part for an opening that never latches. Watch the geometry when pairing the two on adjacent doors: the Emtek 8080 sits at 3-5/8 inch center to center against the Omnia dummy at 5-1/2 inch.

Solid brass. Both the material and the substrate are brass, not a brass-plated zinc or steel casting, which is why it takes the full range of brass finishes including the unlacquered US3NL that patinas. Emtek styles it as American Classic, and it is part of their brass collection.

No. It is a mechanical keyed entry lockset with a brass cylinder and a physical key, with no keypad, no battery and no electronics of any kind. If you are outfitting a rental and want codes rather than keys, this is not the product; if you want a single key across several doors, the keyed-alike option on this set does that mechanically.
