Emtek 8224 Belmont Plate 3-3/8" CTC - Sideplate Lockset - Brass Thumbturn Privacy Non-Keyed Style

Yes. The 8224 Belmont sideplate set uses one standard 2-1/8 inch cross bore and works on doors 1-3/8 to 1-3/4 inches thick. The latch backset is adjustable, so you can set it at 2-3/8 or 2-3/4 inches to match the existing bore location. Where the prep differs from a rosette lockset is the sideplate itself: the plate spans 3-3/8 inches center to center, so the face of the door needs to be clear for the plate footprint around the bore.

It ships as a complete set: the sideplates, your chosen knob or lever, the latch, and the strike plate. Inside trim is a brass thumbturn for privacy, so no key or cylinder is involved. The only thing you pick separately at order time is the knob or lever style, the handing, and the backset.

Handing is required on the order for this set. Emtek calls for handing on leversets, and the order form asks for right hand or left hand either way. Stand outside the door (the hallway side for a bed or bath): if the hinges are on your right it is right hand, on your left it is left hand.

Measure from the edge of the door to the center of the existing 2-1/8 inch bore. That distance is your backset. The Belmont 8224 latch is adjustable and ships standard for 2-3/8 inches, which is the common residential interior figure; specify 2-3/4 inches if your door is prepped that way. Getting this wrong means the latch will not reach the strike.

The Emtek 8224 Belmont sideplate lockset is a non-keyed privacy/bed/bath function with a brass thumbturn, so it is intended for bedrooms and bathrooms rather than an exterior opening. For a keyed sideplate application, the Omnia D12036A is a single cylinder deadbolt lever lockset in solid brass, which keys from the outside. If you need the door to key from both sides - common on a door with glass nearby - the Omnia D12036AC is the double cylinder version of the same deadbolt lever lockset with a sideplate design.

The Emtek 8224 Belmont ships as a complete working set with latch and strike plate and locks with a thumbturn, so it is not the right choice for a non-latching closet or a pair of inactive doors. For that opening, the Omnia D12036PD is a solid brass dummy deadbolt lever lockset with plates, a double dummy function with no latch mechanism. Note its plates are 5-1/2 inch center to center, while the Belmont plate is 3-3/8 inch CTC, so the two do not visually match on adjacent doors.

No. The Omnia D12036A is a single cylinder deadbolt lever lockset in solid brass, a keyed product. The Emtek 8224 Belmont is a tubular privacy/bed/bath lockset with no key and a brass thumbturn on the inside face. Substituting the D12036A onto a bedroom or bath door means occupants need a key rather than a thumbturn, and the door prep differs because the Belmont uses a single standard 2-1/8 inch cross bore with a 2-3/8 or 2-3/4 inch backset latch.

Non-keyed. This is a privacy/bed/bath function: a brass thumbturn on the inside locks the door, and there is no cylinder or key on the outside. It is the right choice for bedrooms and bathrooms, not for an entry or an office you need to key.

No. The 8224 Belmont plate takes any Emtek brass knob or lever style, so you can run a Belmont Knob for a traditional look, a Stuttgart or Athena lever for something contemporary, or a crystal knob like Windsor or Georgetown. The plate is the constant; the trim is your choice.

Five: Oil Rubbed Bronze (US10B), Satin Nickel (US15), Polished Brass Lifetime (US3), Unlacquered Brass (US3NL), and French Antique (US7). Worth knowing before you spec a whole floor: Unlacquered Brass is a living finish that will darken and patina with handling, while Polished Brass Lifetime is coated to stay bright. Mixing the two on adjacent doors will not match after a year.

It is a residential product. The 8224 is a tubular bored lockset in solid brass with a privacy thumbturn, built for houses, apartments, and hospitality-style interiors. For a commercial corridor or a rated opening you want a Grade 1 or Grade 2 cylindrical or mortise lock instead.

They are different plate geometries. The Emtek 8224 Belmont sideplate is 3-3/8 inch center to center, while the Omnia D12036PD dummy set uses plates at 5-1/2 inch center to center. If your goal is a consistent look down a hallway, stay within one plate dimension and switch function instead - the Belmont covers the privacy bed and bath doors in brass, and the Omnia D12036A single cylinder or D12036AC double cylinder cover keyed openings on the Omnia plate.
