Emtek 8997 Delaware 5-1/2" Center-to-Center Keyed Sideplate Lockset, Passage/Double Keyed - Brass Tubular

It drops into one standard 2-1/8 inch cross bore, so a door already prepped for a bored knob or lever set takes it without new boring. Backset is adjustable for 2-3/8 or 2-3/4 inches, and it covers doors from 1-3/8 to 1-3/4 inches thick. The sideplate spans 5-1/2 inches center to center, so the plate itself needs that much clear stile above and below the bore.

Double cylinder is the function: it takes a key from outside and from inside, with no thumbturn. That is the choice people make on a door with glass beside or in it, so breaking the glass does not get a hand to a turn piece. The trade off is that anyone inside needs a key to get out, which is why many jurisdictions restrict double cylinder on a primary egress door. If you want key outside and turn inside, order a single cylinder version instead.

Handing is required, right hand or left hand, and it matters for leversets in particular since the lever has to sweep down toward the latch. Stand outside the door: if the hinges are on your right it is right hand. Get it wrong on a lever and the trim points the wrong way.

Yes. Keying is specified at order time as keyed alike or keyed different, and you can also give a key code if you are matching an existing Emtek cylinder. Keyed alike is what you want on a front and back door pair; keyed different is the default when the openings serve separate tenants or units.

It is a residential-rated tubular lockset, so it belongs on houses, condos, and light multi-family interiors and entries rather than on high-traffic commercial openings. For a commercial corridor or a heavily cycled entrance, you want a Grade 1 or Grade 2 cylindrical or mortise lock, not a residential tubular.

The Omnia D12036AC is a double cylinder deadbolt lever lockset in solid brass with a sideplate design, so it covers the same key-both-sides requirement in the same style of long plate. If you only need key outside, the Omnia D12036A is the single cylinder version. For an inactive door of a pair or a closet where nothing has to latch, the D12036PD is a double dummy on 5-1/2 inch centers, the same spacing as the Delaware plate.

The Omnia D12036AC is a double cylinder deadbolt lever lockset built on a sideplate design in solid brass, which puts it in the same double cylinder keyed function as the Emtek 8997 Delaware. Both take a key on each side rather than a thumbturn inside, so the interior stays keyed for a glass-panel or sidelight door. The Emtek 8997 is brass with a 5-1/2 inch center-to-center spacing between the sideplate bores; the Omnia D12036PD in that same family is also listed at 5-1/2 inch center to center, so the sideplate proportions run together across the two lines. The practical difference is trim: the Emtek 8997 is ordered with a knob or lever style specified separately, while the Omnia is catalogued as a lever lockset.

The Emtek 8997 Delaware is a double cylinder set, so it is keyed on both faces of the door. Where the inside face should not need a key, the Omnia D12036A is a single cylinder version of the same solid brass deadbolt lever lockset, keyed outside only. That is the usual choice for a main entry with no glass within reach of the lock, and for occupancies where a key-operated interior lock is a problem for egress. Keep the 8997 Delaware where the interior side genuinely has to stay locked against someone reaching through a light or sidelight.

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). It is solid brass from the Emtek brass collection, so it matches other brass-collection trim. Unlacquered brass is the one to watch: it is left bare and will patina over time rather than staying bright.

A sideplate lockset mounts the knob or lever on a long backplate rather than a small round rose. The 8997 Delaware plate runs 5-1/2 inches center to center, which is the visual reason people choose it, and it needs that much unbroken stile. On a narrow stile or a door with a lite close to the lock edge, a rose-mounted set is the safer fit.

An Emtek 443 Interconnect Device can be added at order time. That is what ties the lockset and a deadbolt together so retracting one retracts the other, which is the usual ask on a rental or a door where people forget the deadbolt. Without it, the lockset stands alone as an entry function set.

Both round corner and square corner latch faceplates are available on the Delaware 8997, so you can match whatever the existing door edge mortise is cut for and skip re-chiseling. Pick the one that matches the mortise you already have.

It is not, despite the similar sideplate appearance and the shared 5-1/2 inch center-to-center spacing. The Omnia D12036PD is a double dummy set - fixed trim, no keyed cylinder and no latching action. The Emtek 8997 Delaware is a double cylinder keyed entry set. If a purchase order was written against the D12036PD for an entry opening, the door will not secure. The keyed peers in that Omnia family are the D12036A for single cylinder and the D12036AC for double cylinder.

No. The Emtek 8997 Delaware is a keyed entry lockset with a working latch and cylinders, so it operates. For a door leaf that only needs to look the same - the inactive leaf of a pair, a closet, or a false panel - the Omnia D12036PD is a double dummy deadbolt lever lockset with plates at 5-1/2 inch center to center. Double dummy means fixed trim on both faces with no latch to retract. Buyers standardizing an entry frequently order the keyed set for the operating leaf and the dummy for the leaf that stays fixed.

The Emtek 8997 Delaware is ordered with the knob or lever style for the inside trim specified as part of the order, across an American Classic range that includes levers, knobs and crystal knobs, in eight finishes from Unlacquered Brass and Polished Brass Lifetime through Oil Rubbed Bronze and Flat Black. The Omnia D12036A and D12036AC are catalogued as lever locksets in solid brass, so the handle form is fixed as a lever by the part number. If a project needs knobs on some openings and levers on others while the sideplate look stays constant, the 8997 Delaware carries that from one part number; if a lever is what the drawing calls for on every door, the Omnia sets land there directly.

Any Emtek brass knob or lever style can be ordered on it, and the choice covers everything from the Ace knob and Spoke knob through the Athena, Luzern and Poseidon levers to crystal knobs like Bristol and Windsor. Remember that picking a lever means handing has to be specified; a knob is symmetrical.
