Emtek 8091 Victoria 3-5/8" C-to-C Keyed Sideplate Lockset, Passage/Double Keyed - Brass Tubular

It uses one standard 2-1/8 inch cross bore, so it drops into a normal bored door prep. Door thickness range is 1-3/8 to 1-3/4 inches, and the backset is ordered as either 2-3/8 or 2-3/4 inches. One thing to check before you order: the sideplate is 3-5/8 inch center-to-center, so the plate covers the door face above and below the bore. If the existing hole spacing or a previous sideplate footprint differs, you will see the outline.

Double cylinder is right. The 8091 is an entry function keyed lockset with a keyed cylinder on both sides, so there is no thumbturn inside. Anyone leaving has to use a key. That is the usual choice for a door with glass beside or in it, since nobody can break the glass and reach a turn piece. It also means you need a key kept accessible inside for egress, and some local codes restrict double cylinder on a required exit door in a dwelling.

Handing is a required selection, right hand or left hand. It matters for the lever styles in particular, since a lever has to point toward the hinge side to sit correctly. Stand outside the door: if the hinges are on your right, it is right hand. Order the backset at the same time, 2-3/8 or 2-3/4 inches, and pick the inside knob or lever style, which is also a required choice.

Yes. Keying is a required selection at order time, either keyed different or keyed alike, and you can also supply an existing key code to have them cut to match hardware you already own. If you are doing a front and back door, choose keyed alike so both take the same key. Remember it is double cylinder, so every one of those doors needs a key on the inside as well.

The Omnia D12036AC is the nearest match. Both are double cylinder sideplate locksets in solid brass: the Emtek 8091 Victoria is a brass tubular entry set with a Double Cylinder keyed function, and the Omnia D12036AC is a double cylinder deadbolt lever lockset with solid brass construction and a sideplate design. The main differences are the trim program and the center-to-center spacing - the Emtek 8091 is 3-5/8 inch center-to-center and can be ordered with any Emtek brass knob or lever style, while the Omnia is supplied as a lever lockset.

Where a thumbturn is required on the inside, look at the Omnia D12036A, which is a single cylinder deadbolt lever lockset in solid brass. The Emtek 8091 Victoria is a Double Cylinder entry set, meaning it takes a key on both sides, which is the condition many egress requirements restrict on a door with glazing nearby. The Omnia D12036A carries a Single Cylinder function for that situation.

It ships as a complete set: the sideplates with the outside trim, the inside knob or lever you select, the latch, and the strike plate. The latch faceplate is available in round corner or square corner so it matches the mortise already cut in the door edge. Nothing else is needed to hang it on a prepped door.

Yes. The inside trim is a separate selection and the list runs to more than eighty options, covering levers (Stuttgart, Athena, Luzern, Coventry, Rope, Rustic), knobs (Victoria, Providence, Egg, Octagon, Square), and crystal knobs (Windsor, Bristol, Georgetown, Old Town). Common practice is a lever inside for easy egress on an entry door and the sideplate handle outside. If you pick a lever, handing has to be specified.

Five: Oil Rubbed Bronze (US10B), Satin Nickel (US15), Polished Brass Lifetime (US3), Unlacquered Brass (US3NL), and French Antique (US7). Worth knowing for a whole house package: Unlacquered Brass is a living finish that will darken and patina with handling, while Polished Brass Lifetime is coated to stay bright. Do not mix the two on adjacent openings and expect them to match a year later.

It is a residential lockset, tubular type, in solid brass. That suits single family homes, condos and high end multi-family unit entries where aesthetics drive the choice. For a commercial opening with heavy cycle counts or a fire rated door assembly, you want a cylindrical or mortise lock built for that duty instead, not a decorative brass sideplate set.

Use a dummy sideplate set rather than a keyed one. The Omnia D12036PD is a solid brass dummy deadbolt lever lockset with plates at 5-1/2 inch center-to-center, with no latch or cylinder, so it is surface applied to an inactive leaf. The Emtek 8091 Victoria is a keyed entry lockset supplied as a complete set with knob or lever, latch and strike plate, and needs a standard 2-1/8 inch cross bore, so it is not the right choice on a non-latching door.

Treat them as separate preps, not interchangeable trim. The Emtek 8091 Victoria is built on a 3-5/8 inch center-to-center sideplate over a standard 2-1/8 inch cross bore with an adjustable 2-3/8 inch or 2-3/4 inch backset, for doors 1-3/8 inch to 1-3/4 inch thick. The Omnia D12036AC is a double cylinder sideplate lever lockset in solid brass with its own plate layout, and the related Omnia D12036PD plates are 5-1/2 inch center-to-center. If the existing plate footprint matters on a retrofit, confirm the spacing before swapping brands.

The Emtek 8091 Victoria is the one built around trim selection: it is a residential brass tubular entry set that can be ordered with any Emtek brass knob or lever style, with handing specified for leversets, in finishes including Oil Rubbed Bronze US10B, Satin Nickel US15, Polished Brass US3, Unlacquered Brass US3NL and French Antique US7. The Omnia D12036A, D12036AC and D12036PD are solid brass lever locksets offered as single cylinder, double cylinder and double dummy respectively, so the choice there is made on function rather than on lever or knob design.
