Emtek EMP8990 EMPowered Colonial 5-1/2" Center-to-Center Keyed Sideplate Lockset, Passage/Single Keyed - Brass Tubular

Yes. The EMP8990 Colonial sideplate lockset uses one standard 2-1/8 inch cross bore and fits doors 1-3/8 to 1-3/4 inches thick. The latch backset is adjustable, and you pick 2-3/8 or 2-3/4 inches on the order. If your door is already bored 2-1/8 inch for a standard tubular lock, the sideplate covers the existing prep.

5-1/2 inches is the distance between the two bore centers on the Colonial sideplate, meaning the knob or lever bore and the keyed cylinder bore sit 5-1/2 inches apart. Measure your existing door prep center of the knob hole to center of the deadbolt hole. If it is not 5-1/2 inches, the sideplate will not line up over both holes.

Handing is required, and you choose Right Hand or Left Hand. It matters for the lever styles in particular, since a lever has to point toward the hinge-side stop. Stand outside the door: if the hinges are on your right, it is right hand.

Yes. Keying is a required selection and you choose Keyed Different or Keyed Alike. There is also a keying-to-code field if you need the cylinders cut to a specific key code so the new locks run on the keys already in use.

No. The EMPowered 8990 sideplate lockset is a residential product, solid brass tubular construction. For an office, school, or multi-family corridor door you want a commercial bored or mortise lock with a stated ANSI/BHMA grade instead. This one suits a house or a low-traffic private entry.

The standard latch ships for a 2-3/8 inch backset, so specify 2-3/4 inches only if your door needs it. Measure from the door edge to the center of the existing bore: 2-3/8 is typical on interior and many residential entry doors, 2-3/4 shows up on thicker or wider-stile entry doors.

The Emtek EMP8990 is an electronic, single cylinder keyed entry sideplate lockset in brass. If the opening does not call for electronic entry, the Omnia D12036A is a single cylinder deadbolt lever lockset in solid brass construction, operated by key and thumbturn rather than a keypad. Both are single cylinder in function, so the difference is the means of entry rather than the security arrangement.

The EMP8990 is built as a single cylinder entry set, so it is keyed on the outside with an inside operation that does not require a key. For a double cylinder arrangement, the Omnia D12036AC is a double cylinder deadbolt lever lockset with sideplate design in solid brass. Check local egress code for your jurisdiction before specifying double cylinder on a dwelling exit door.

It ships as a complete set: the knob or lever you selected, the latch, and the strike plate. The latch faceplate is available round corner or square corner so it can match an existing mortise in the door edge. It is a single cylinder keyed entry function, so the interior side is thumbturn-operated rather than keyed.

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). Unlacquered Brass is the one that will patina over time rather than hold its original tone, so pick it only if a living finish is what you want.

Yes, and it is a required choice. The inside trim can be ordered with any Emtek brass knob or lever style, from levers like Stuttgart, Athena, Milano, and Rustic to knobs like Egg, Providence, Square, and the crystal knobs such as Windsor and Georgetown. That lets you keep one door style consistent with the rest of the openings in the house.

Both are solid brass sideplate-style sets. The Emtek 8990 is a single cylinder keyed entry, key outside and turn inside. Omnia offers the same footprint in three functions: the D12036A single cylinder, the D12036AC double cylinder (keyed both sides, for a door with glass nearby), and the D12036PD double dummy with no working latch for a fixed or inactive leaf. If you need key-both-sides or a dummy, the Omnia versions cover those; the Emtek 8990 does not.

The EMP8990 is a keyed entry sideplate lockset and is not intended for a non-latching leaf. For a leaf that only needs a pull with no working latch, the Omnia D12036PD is a solid brass double dummy deadbolt lever lockset with plates at 5-1/2 inch center to center, the same center to center spacing the EMP8990 uses. Note it is an Omnia trim design, so the sideplate and lever styling will not match Emtek's Colonial plate exactly.

Treat them as separate systems rather than a drop-in swap. The Emtek EMP8990 uses a 5-1/2 inch center-to-center sideplate over a standard 2-1/8 inch cross bore with an adjustable 2-3/8 or 2-3/4 inch backset, and it is an electronic keyed entry set, so it also carries the keypad and battery hardware behind the plate. The Omnia D12036PD is listed at the same 5-1/2 inch center to center, but it is a dummy function with plates and no working latch, so it will not fill an entry opening. Confirm plate footprint and screw locations against the existing prep before ordering any of them as a replacement.

The Emtek EMP8990 is designated for residential use and is a tubular lock type, which suits apartment, condo and single-family entries rather than high-traffic commercial openings. The Omnia D12036A and D12036AC sideplate deadbolt lever locksets are solid brass single and double cylinder options in the same decorative sideplate style. For a building requiring a graded commercial mortise or cylindrical lock, none of these decorative brass tubular sets is the correct starting point - specify from a commercial-rated line instead.
