Deltana BBR213 Bell Button, Round Contemporary

The BBR213 is a mechanical push button on a low-voltage bell circuit, wiring in place of your old button on the same two conductors running to the transformer and chime. It does not carry its own chime, transformer, or wireless transmitter, so it is a swap for a wired button and not a replacement for a wireless doorbell kit or a video unit.

The BBR213 is a round contemporary bell button in solid brass, 2-1/4 inch diameter, sold as the button unit itself. The Emtek 2400 is an American Classic brass doorbell supplied as a plate and button together on a Regular rosette. If you are replacing just the button on an existing opening, the BBR213 covers it; if you need the backplate as well, the 2400 brings both pieces.

The Deltana BBR213 is a round contemporary button with a plain 2-1/4 inch face. For a rope-detailed look, the Emtek 2401 American Designer brass doorbell uses a Rope rosette and ships with the plate and button together.

Nine finishes: Polished Brass, PVD Polished Brass, Antique Brass, Antique Nickel, Brushed Nickel, Polished Chrome, Brushed Chrome, Oil Rubbed Bronze, and Paint Black. If you are matching entry hardware across a building, the PVD Polished Brass is the one to look at for exterior use, since PVD is a deposited coating rather than a lacquer over raw brass.

Solid brass throughout, not a plated zinc casting. That matters on an exterior entry that takes weather and daily thumbs: the substrate is brass under whatever finish you pick, so a scuff on an Oil Rubbed Bronze or Antique Brass button wears to brass rather than exposing a different metal underneath.

Deltana rates the BBR213 for commercial use, and it is an exterior-hardware item. For a multi-family or office entry where you are standardizing the look, the round contemporary profile in one finish across every door is the usual play, and the nine-finish range lets you match existing lever and pull finishes rather than settle.

Shape of the footprint, mainly. The BBR213 is a single 2-1/4 inch round brass button with no surrounding plate. The Emtek doorbells pair a button with a plate, and the plate shape is the choice: 2400 regular rosette, 2401 rope rosette, 2402 oval, 2403 rectangular. Round trim on the rest of the entry points to the BBR213 or the Emtek 2400; a rectangular or oval jamb detail points to the 2403 or 2402. Rope rosette on the 2401 is a traditional look that will fight a contemporary entry.

Both are solid brass. The BBR213 is a commercial-rated brass button offered in nine finishes - PVD Polished Brass, Polished Brass, Antique Brass, Oil Rubbed Bronze, Brushed Nickel, Antique Nickel, Paint Black, Polished Chrome, and Brushed Chrome - so one part number covers a mixed-finish portfolio. The Emtek 2400, 2401, 2402, and 2403 are brass doorbells differentiated by rosette shape: Regular, Rope, Oval, and Rectangular. Deltana varies the finish on one round form; Emtek varies the plate shape.

Sold each, one button per unit of measure, so 40 openings is 40 pieces. All nine finishes are the same BBR213 body, so a property standardizing across a portfolio can hold one model number and vary only the finish by building.

By the identity that separates the two part numbers, no - both are American Classic brass doorbells supplied with plate and button, and the model split is the rosette: the 2402 is Oval and the 2403 is Rectangular. Pick by the shape you want on the jamb.
