Emtek 8990 Colonial 5-1/2" Center-to-Center Keyed Sideplate Lockset, Passage/Single Keyed - Brass Tubular

Yes. The 8990 Colonial uses one standard 2-1/8 inch cross bore, so it drops into a door already prepped for a normal tubular lockset. Backset is adjustable between 2-3/8 and 2-3/4 inches, the two usual bored-door backsets, and it covers doors 1-3/8 to 1-3/4 inches thick. The sideplate itself is a long escutcheon with 5-1/2 inch center-to-center spacing between the cylinder and the knob or lever spindle, so the door face needs to be clear enough for that plate even though the bore is standard.

If you are putting a lever on it, yes. Handing is required for a leverset, so you need to establish right or left hand at the door before you order. Knob trim is the simpler path if you are unsure, but the order still asks for handing either way, so measure at the opening first: stand outside the door, and the side the hinges sit on tells you the hand.

The 8990 is a single cylinder entry lockset: key outside, thumbturn or knob release inside, no key required to get out. On the order you pick keyed different or keyed alike across multiple units, and there is a field for keying to an existing code if you are matching locks already in the building. If you specifically need a key on both sides, this is not that lock, and a double cylinder sideplate such as the Omnia D12036AC is the configuration to look at instead.

Yes, but you have to say so on the order. The standard latch supplied is set for a 2-3/8 inch backset; specify 2-3/4 inches if that is what your door is bored for. Measure from the door edge to the center of the 2-1/8 inch bore to confirm which you have before ordering.

The Omnia D12036A is the nearest match. The Emtek 8990 Colonial is a keyed entry sideplate lockset with a single cylinder keyed function in brass, and the Omnia D12036A is a single cylinder deadbolt lever lockset in solid brass. Both give you one keyed cylinder on the exterior with a brass sideplate trim, so a buyer standardizing on brass sideplate hardware across an entry can specify either and get single cylinder operation.

The Emtek 8990 Colonial is a single cylinder lockset, keyed on one side only. For an opening that has to be keyed from inside as well - a door with glass beside it, or a commercial back entry where you want to control egress by key - the Omnia D12036AC is a double cylinder deadbolt lever lockset in solid brass with a sideplate design. That gives you a cylinder on both faces rather than a thumbturn on the interior.

No - they look alike on the door but do different jobs. The Omnia D12036PD is a double dummy lever lockset, meaning both sides are fixed trim with no latch or cylinder behind them. The Emtek 8990 Colonial is a keyed entry lockset with a single cylinder, supplied with latch and strike plate and prepped for a standard 2-1/8 inch cross bore with an adjustable 2-3/8 or 2-3/4 inch backset. If the opening has to latch or lock, the dummy will not do it; if it only needs to look the part, the entry lockset is more hardware than the door requires.

It ships as a complete set: the sideplates with the exterior keyed cylinder, your chosen knob or lever, the latch, and the strike plate. The latch faceplate can be round corner or square corner to match what is already routed into your door edge. Nothing else is needed to hang it on a prepped door of 1-3/8 to 1-3/4 inches.

A sideplate lockset like the Emtek 8990 puts the cylinder and the knob or lever on one continuous brass plate at 5-1/2 inch center-to-center, so it reads as a single piece of hardware rather than two separate roses stacked on the door. It is the look people want on colonial and traditional front doors. The trade-off is that the plate covers a fixed vertical span, so the existing bore spacing on a retrofit has to suit it. Separate trim and deadbolt gives you freedom on spacing; the sideplate gives you the unified appearance.

Either. The 8990 accepts any Emtek brass knob or lever style for the inside trim, which runs from the traditional (Providence, Waverly, Victoria, Rope and Ribbon and Reed knobs, Coventry and Rustic levers) through crystal knobs (Windsor, Georgetown, Hampton, Old Town) to the modern bar and square families (L-Square, T-Bar, R-Bar in faceted, hammered, knurled, Tribeca and white marble). Levers are the usual pick for accessibility and for anyone carrying tools or groceries; note that choosing a lever makes handing a hard requirement.

For the active leaf, the Emtek 8990 Colonial handles the keyed entry side. For an inactive leaf that only needs the same appearance with no working latch, a double dummy sideplate set such as the Omnia D12036PD, also at 5-1/2 inch center-to-center, is the type of part to pair with it. It is a different brand, so the plate profile and finish will not match the Emtek exactly; if visual match matters on a pair of doors, order the dummy trim from the same manufacturer family as your active lock.

Emtek's 443 interconnect device is offered as an optional add-on with the 8990. An interconnect ties the lockset and the deadbolt so a single motion on the inside retracts both, which is what you want on a rental or a multi-family unit where a resident should be able to get out in one action. Add it at the time of order.

It is residential hardware. Emtek lists the 8990 Colonial as residential, so for apartment unit doors, single family entries, and interior residential work it is on spec. For a commercial opening with traffic ratings or code-driven hardware requirements in the drawing, this is not the family to spec.

For a door that only needs matching sideplate trim - an inactive leaf of a double door, or a closet door pulled shut by hand - the Omnia D12036PD is a solid brass dummy deadbolt lever lockset with plates on 5-1/2 inch center to center. It is a double dummy, so there is no latch and no cylinder. The Emtek 8990 Colonial is a keyed entry lockset that ships as a complete set with knob or lever, latch and strike plate, and shares the same 5-1/2 inch center-to-center dimension, so the two can sit side by side on adjacent leaves and read alike.

The Emtek 8990 Colonial can be ordered with any Emtek brass knob or lever style, so the same 5-1/2 inch center-to-center keyed sideplate can be finished with a Cortina lever, an Egg knob, a crystal knob or a knurled T-Bar without changing the lockset itself. The Omnia comparables in solid brass - the D12036A single cylinder, the D12036AC double cylinder and the D12036PD double dummy - are each specified as lever locksets. For a property manager matching one trim design across a building, the difference is whether the trim is chosen separately from the lock body or comes fixed with it.

Solid brass throughout, from Emtek's brass collection. Finish choice drives how it ages: Polished Brass Lifetime (US3) is coated to hold its shine, while Unlacquered Brass (US3NL) is bare brass that patinas over time, which is the point of it on a period house. Oil Rubbed Bronze (US10B) and French Antique (US7) are living finishes as well. Satin Nickel (US15), Pewter (US15A), Flat Black (US19), and Polished Chrome (US26) round out the range. This is residential-grade hardware, not a commercial-traffic lockset.
