Emtek 8981 Quincy 5-1/2" Center-to-Center Keyed Sideplate Lockset, Passage/Double Keyed - Brass Tubular

Both. The 8981 Quincy is built for doors 1-3/8 to 1-3/4 inches thick, which covers standard interior doors and full-thickness exterior doors alike. There is a door thickness field on the order form, so state your actual thickness when you place the order and the correct latch and spindle length come with the set.

One standard 2-1/8 inch cross bore is all the 8981 needs, with the latch bored for either a 2-3/8 or 2-3/4 inch backset. That is the same prep a common residential knob or lever set uses, so a door already drilled for a bored lockset takes it without new boring. The sideplates cover the face at 5-1/2 inch center-to-center between the knob or lever and the cylinder, so check that the plate footprint clears any old rose or deadbolt hole.

Double cylinder, yes. The 8981 Quincy takes a key on the outside and a key on the inside, so there is no thumbturn to reach through broken glass and operate. That is why it gets specified on doors with glass lites or a sidelite. The tradeoff is egress: anyone leaving has to have a key in hand, and many jurisdictions restrict double cylinder locks on a required exit door. If you want key outside and turn inside, order the single cylinder version of the Quincy sideplate instead.

Yes if you are picking a lever. Handing is required on a leverset so the lever points the right way toward the jamb, and right hand and left hand are both offered. Knobs are symmetrical, but the order form still asks for handing, so stand outside the door: if the hinges are on your right it is a right hand door.

Usually, because it ships with its own strike plate and the latch is adjustable between the two standard backsets, 2-3/8 and 2-3/4 inch. If your existing strike is a plain lip strike mortised at standard height, the new latch lines up with it. Where it will not is a jamb prepped for a different faceplate shape, so note that the latch faceplate comes round corner or square corner and match what is cut in your edge and jamb.

The Emtek 8981 Quincy is a keyed entry sideplate lockset with a Double Cylinder keyed function in brass, meaning a key is required from both sides. The Omnia D12036AC is the closest peer: a double cylinder deadbolt lever lockset in solid brass with a sideplate design. Both put a key on the interior as well as the exterior, which is the arrangement specified for doors with glass near the lock. The Emtek 8981 is a 5-1/2 inch center-to-center set and the Omnia D12036AC is a lever lockset rather than a knob or lever choice, so the interior trim decision differs between them.

The Emtek 8981 Quincy is a Double Cylinder keyed set, which requires a key to retract the bolt from the interior and is what many egress requirements prohibit on an exit door. For those openings the Omnia D12036A is the single cylinder counterpart in the same solid brass lever lockset family, keyed on the exterior only. Property managers standardizing a building often run the double cylinder Emtek 8981 on glass-adjacent doors and the single cylinder set on rated egress doors so the interior operates without a key.

Keyed alike is a no-charge option on the 8981, so a run of Emtek locks ordered together can all run on one key. If you are adding to doors that are already installed, there is a keying-to-code field where you enter your existing key code and the cylinders get cut to match. Order keyed different if each opening should be on its own key.

Sold as a complete set: the outside sideplate with cylinder, the inside knob or lever trim you selected, the latch, and the strike plate. Nothing else is needed to lock the door. The one add-on worth considering is the Emtek 443 Interconnect Device, offered as an option, if you want the lockset tied to a deadbolt so one motion retracts both.

Eight, all on solid brass: 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). Two of those behave differently over time: Unlacquered Brass has no coating and will patina with handling, while Polished Brass Lifetime is finished to hold its shine. If you are matching hardware already on other doors, that distinction is the one that trips people up.

Residential. The 8981 Quincy is a tubular bored lockset in solid brass, built for houses and residential trim, not for the cycle counts of a school corridor or an office entry. Property managers doing apartment units and single family rentals use this class of lock routinely; for a high-traffic commercial door you want a cylindrical or mortise lock built for that duty instead.

Any Emtek brass knob or lever style, and the inside trim choice is part of the order. That spans levers like Stuttgart, Helios, Athena, Luzern, Milano and Rustic, knobs like the Ace, Spoke, Egg, Octagon and Providence, crystal knobs like Bristol, Windsor and Georgetown, and the L-Bar, T-Bar and R-Bar families in faceted, hammered, knurled, Tribeca and white marble treatments. It means you can carry one trim design across a house and still have the Quincy sideplate on the entry.

A sideplate set puts the cylinder and the knob or lever on one long backplate covering both, with 5-1/2 inches between their centers, so the door reads as a single piece of hardware rather than two. Mechanically the 8981 is still a tubular entry lock working off one 2-1/8 inch bore, so it installs like a lockset, not like a lockset plus a separate deadbolt bore. If you want the deadbolt style look without a working lock, on a dummy or inactive leaf, the Omnia D12036PD is a solid brass double dummy deadbolt lever set on 5-1/2 inch center-to-center plates.

The 8981 Quincy is double cylinder, keyed on both faces. If a keyed inside is not what you want, the Omnia D12036A is a single cylinder deadbolt lever lockset in solid brass, and Omnia's D12036AC is the double cylinder version of the same set if you would rather stay in that line. Single cylinder is the usual pick for a door with no glass near the lock, since it lets anyone leave without hunting for a key.

No. The Emtek 8981 Quincy is a keyed entry lockset with a tubular latch, so it is built to latch and lock rather than to sit on a fixed leaf. For an inactive or false door the Omnia D12036PD is a double dummy solid brass deadbolt lever lockset with plates at 5-1/2 inch center to center, which is the same center-to-center layout as the Emtek 8981 Quincy. That matching dimension is what lets a dummy on the inactive leaf line up with a working keyed set on the active leaf of a pair.

It is not. The Omnia D12036PD is a double dummy, meaning the trim is fixed on both faces with no latch and no cylinder, so it will not secure an entry opening. The Emtek 8981 Quincy is an entry function set with a Double Cylinder keyed arrangement. The two carry a similar sideplate appearance, which is why they get confused, but a locksmith ordering for a keyed opening wants either the Emtek 8981 Quincy or the double cylinder Omnia D12036AC.

The Emtek 8981 Quincy takes any brass knob or lever style for the inside trim, so knob options such as the Round Knob, Octagon Knob, or Windsor Crystal Knob are ordered on the same keyed sideplate set. The Omnia comparables in the same 5-1/2 inch sideplate format are lever locksets: the D12036A single cylinder, the D12036AC double cylinder, and the D12036PD double dummy. For a knob interior on a keyed sideplate opening the Emtek 8981 Quincy is the set that carries it.
