Deltana BBSR333 Bell Button, Rectangular with Rope Pattern

The BBSR333 measures 3-1/4 x 1-1/4 inches overall. That is a rectangular plate footprint, so it covers a small round or rectangular cutout from a previous button as long as the old opening falls inside those dimensions. Measure the existing hole and the flat area of the trim or brick mould before ordering, since a narrow casing needs at least 1-1/4 inches of flat width to seat the plate.

The BBSR333 is the pushbutton and its rope-patterned plate only. It replaces the button at the door and wires into a low voltage bell circuit you already have, transformer and chime included. If you are starting from nothing and want the button and its mounting plate supplied together as a set, the Emtek 2401 American Designer brass doorbell ships as a plate and button assembly, and Emtek also offers the same in a plain rectangular rosette as the 2403.

The Emtek 2403 American Classic Brass Doorbell with Plate and Button uses a Rectangular rosette with no rope detailing, so it gives the same rectangular footprint in a plainer face. The Deltana BBSR333 is the rectangular brass button with the rope pattern worked into the border. Both are brass doorbell buttons for an entry door; the choice is whether the surrounding trim on the opening is roped or plain.

The Emtek 2401 American Designer Brass Doorbell with Plate and Button carries a Rope rosette, matching the rope pattern of the BBSR333. The Deltana BBSR333 is a solid brass rectangular bell button measuring 3-1/4 inches by 1-1/4 inches, so the difference between them is the shape of the surrounding plate: the BBSR333 is rectangular with the rope pattern worked into the rectangle, while the 2401 puts the rope on a rosette-style plate. If the rope motif is what has to match other trim on the entry, either one carries it.

The Deltana BBSR333 needs a 3-1/4 inch by 1-1/4 inch footprint on the casing. Where the trim will not take that rectangle, the Emtek 2402 American Classic Brass Doorbell with Plate and Button uses an Oval rosette and the Emtek 2400 American Classic Brass Doorbell uses a Regular rosette, both brass doorbells with plate and button in a rosette rather than rectangular format. Measure the flat of the casing before committing, since the rectangular plate is the one that most often runs past the brick mould.

Solid brass, both in the plate and the substrate, not a plated zinc casting. That matters on an exterior door where the button sits in weather and gets touched every day: brass will not swell and crack the way a plated pot metal button does when moisture gets under the finish.

Nine finishes: polished brass, PVD polished brass, antique brass, oil rubbed bronze, brushed nickel, antique nickel, polished chrome, brushed chrome, and paint black. If you are matching a fleet of entries, the PVD polished brass is the one to specify where the button faces weather, since PVD is a deposited coating rather than a lacquer and holds its color outdoors longer than standard polished brass.

Deltana lists the BBSR333 as commercial exterior hardware, so it is the button to specify for an apartment entry, a leasing office, or a multi-family building where it gets pressed far more than a single-family front door would.

The BBSR333 is one model in nine finishes, so a property manager can hold a single part number across an entire building and pick the finish per entry. Brass entries take polished or antique brass, nickel entries take brushed or antique nickel, and dark bronze packages take oil rubbed bronze or paint black. The plate is the same 3-1/4 x 1-1/4 inch rectangle in every finish, so the door prep does not change between them.

They are four separate rosette shapes in Emtek's brass doorbell line: the 2400 is the Regular rosette, the 2401 the Rope rosette, the 2402 the Oval rosette, and the 2403 the Rectangular rosette. Each is supplied as a brass doorbell with plate and button. Finish is a separate axis from shape, the way the Deltana BBSR333 is one rectangular rope-pattern button offered in finishes including Polished Brass, Oil Rubbed Bronze, Brushed Nickel and Polished Chrome. So when a facility is standardizing an entry, the part number picks the shape and the finish code picks the appearance.

Do not assume it will. The Deltana BBSR333 is a 3-1/4 inch by 1-1/4 inch solid brass rectangular button, and the Emtek 2403 is described by its Rectangular rosette rather than by that footprint, so the two share a shape family but are not a stated dimensional match. On a replacement where the old plate has left a mark or an oversized hole in the casing, work from the measured opening rather than from the shape name, and expect to touch up or plug the casing if the new plate lands smaller.
