Emtek EMP8980 EMPowered Quincy 5-1/2" Center-to-Center Keyed Sideplate Lockset, Passage/Single Keyed - Brass Tubular

Both. The EMP8980 covers a door thickness range of 1-3/8 to 1-3/4 inches, which takes in standard commercial-weight residential doors and the thinner older interior doors. There is a Door Thickness entry on the order form, so give the actual measured thickness of your slab when you order rather than assuming.

One standard 2-1/8 inch cross bore is all the EMP8980 needs, with an adjustable latch that sets to either a 2-3/8 or 2-3/4 inch backset. If your door already carries a 2-1/8 inch bore on one of those two backsets (the two usual bored-door backsets), the lockset drops into the existing prep. The sideplate itself is a 5-1/2 inch center-to-center escutcheon, so it covers a longer footprint than a plain rosette set and will hide minor wear around the bore.

It is a residential product. For an apartment turn, a condo, a single-family entry or a boutique hospitality door it is the right kind of set, but for a high-traffic commercial opening you want a commercial-grade bored or mortise lock instead. The tubular brass construction here is built around residential duty.

It ships as a complete set: the knob or lever, the latch, and the strike plate. The inside trim comes pre-configured with the Quincy rosette. What you do have to pick is the inside knob or lever style, the handing, the backset, and the keying arrangement. Nothing about the mechanical set is sold separately, but the latch faceplate comes as either round corner or square corner, so match that to the mortise already cut in your door edge.

Yes. Keying is a required selection on the order: keyed different, or keyed alike so a single key opens every set you order together. There is also a keying-to-code field if you already have a key code on file and want the new locks cut to match what is on your other openings. It is a single cylinder entry function, so it is keyed outside and thumbturn or unlocked inside.

The Omnia D12036A single cylinder deadbolt lever lockset is the near equivalent in that arrangement. The Emtek 8980 is an entry function tubular lockset on a 5-1/2 inch center-to-center sideplate with single cylinder keying, so the latch and the key cylinder are part of one trim assembly. The Omnia D12036A pairs a lever with a deadbolt on a sideplate and is also single cylinder, so the key throws a deadbolt rather than releasing the latch. Both are solid brass. Choose the Omnia when the opening calls for a deadbolt bolt in the plate and the Emtek 8980 when the keyed function is on the latch itself.

The Omnia D12036AC is the double cylinder option. It is a solid brass deadbolt lever lockset with a sideplate design and a double cylinder function, meaning a key is required on the interior as well as the exterior - the arrangement often specified for a door with glass within reach of the thumbturn. The Emtek 8980 sideplate lockset is single cylinder keyed, so the inside trim operates without a key. Note that double cylinder locking is restricted on egress doors under many local codes, so confirm the requirement for the facility before specifying it.

The Omnia D12036PD is the dummy version - a solid brass dummy deadbolt lever lockset with plates on 5-1/2 inch center to center, with a double dummy function. It mounts surface trim on both faces with no latch and no cylinder, which is what an inactive leaf or a closet pair takes. The Emtek 8980 is an entry function keyed lockset with a working latch and a single cylinder, so it is not the part for an opening that never latches. Ordering the dummy for the inactive leaf and the keyed 8980 for the active leaf keeps the sideplate appearance consistent across the pair.

Any Emtek brass knob or lever works with it, and the choice is wide: modern bar and square pulls (L-Square, T-Bar, R-Bar in faceted, hammered, knurled, Tribeca and white marble), classic levers like Cortina, Milano, Turino, Merrimack and Wembley, traditional knobs like Egg, Melon, Providence and Waverly, and crystal knobs including Bristol, Windsor, Georgetown and Old Town. Pick one style for the whole floor and every door reads as a set even if the functions differ.

Eight finishes: 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 is meant to patina with handling, while the lifetime polished brass holds its shine. If you are matching other doors in a building, that distinction is what usually catches people out.

A sideplate set like the Quincy puts the key cylinder and the operating trim on one 5-1/2 inch center-to-center plate, so you get a single prep and a single continuous piece of hardware on the face of the door. Choose it when you want the long-plate look and one bore instead of two. If you want the security of a separate deadbolt throwing above the latch, that is a different product and needs its own bore.

The EMP8980 is single cylinder: keyed from the outside only. If your door has glass within reach of the inside trim and you want a key required on both sides, you need a double cylinder set instead, such as the Omnia D12036AC double cylinder deadbolt lever lockset with sideplate design. Omnia also makes a single cylinder counterpart, the D12036A, if you are cross-shopping brands.

The EMP8980 is an entry function, so it locks and takes a key. For an inactive leaf or a pull-only opening you want a dummy set on the same 5-1/2 inch center-to-center layout, like the Omnia D12036PD double dummy brass sideplate lockset, which is built to that same 5-1/2 inch spacing. That keeps the plate footprint consistent from door to door even where no locking is needed.

They are not interchangeable trim-for-trim even though both are brass sideplate assemblies. The Emtek 8980 is a tubular entry lockset - the key operates the latch through a 2-1/8 inch cross bore with an adjustable 2-3/8 inch or 2-3/4 inch backset, and it is part of the EMPowered electronic line. The Omnia D12036A is a deadbolt lever lockset, so its keyed cylinder drives a deadbolt rather than the latch. Swapping one for the other changes how the door is secured and what bores the door needs, so treat it as a function change rather than a straight substitution.
