Deltana UFBD4505 Round Universal Floor Door Bumper Dome Cap 1-5/8", Solid Brass

Solid brass. Both the material and the substrate on the UFBD4505 are brass, so the finish sits on a brass body rather than on zinc or steel. That matters on a floor stop more than most hardware, because a floor mounted bumper takes shoe traffic, mop water and vacuum strikes, and a plated pot metal body chips at the base where it meets the floor. The dome cap measures 1-5/8 inches.

Depends on how far your door swings past the wall and how much floor projection you can live with. A low dome like the Deltana UFBD4505, at 1-5/8 inches across, sits close to the floor and catches the bottom rail or the face of the door near the bottom, so it is the quieter option in a corridor where a taller stop is a trip hazard. A gooseneck arm reaches up and out to catch the door higher, which you need when the door clears the dome or when the swing puts the contact point well off the floor line. ZenSupply carries both patterns: the Delaney Gooseneck Floor Door Stop and the Orca Hardware 22HD Series Goose Neck Floor Stop on the gooseneck side, and the Orca 23LP Series low rise dome on the low profile side.

Stop only. The UFBD4505 is a dome bumper that arrests the swing and protects the wall; there is no catch or magnet to keep the leaf standing open. If you need the door to stay put, that is a different part. ZenSupply carries the Ives FS40 / FS41 / FS42 / FS43 automatic floor stop and holder, which has adjustable door-to-floor clearance, and the SOSS MDH magnetic door holder and stop at 3-5/16 by 1-3/4 inches. The Orca 22HD gooseneck is also catalogued as a door holder.

A dome bumper like the Deltana UFBD4505 sits low and close to the floor, so the door contacts it near the bottom edge. When the stop has to reach up to the door face instead, a gooseneck stop is the alternative: the Delaney Gooseneck Floor Door Stop 40118X, the Emtek 2253 Goose Style Door Stop, and the Orca Hardware 22HD Series goose neck floor stop with a black tip all use the raised riser form. The Orca 22HD is listed for 1-3/8 inch or 1-3/4 inch doors and functions as a door holder.

The Deltana UFBD4505 is a solid brass dome bumper flagged for commercial use. Where a facility wants a heavy duty rating stated, the Ives FS13 heavy-duty brass floor dome stop has a replaceable rubber bumper, and the Ives FS17 heavy-duty brass floor dome stop uses a rubber bumper. Both keep the brass dome form. The FS13 replaceable bumper matters for a facility that plans to service the stop rather than swap the whole unit.

A low dome bumper such as the Deltana UFBD4505 at 1-5/8 inches only works if the door bottom actually reaches it. Where the undercut is generous or varies, the Ives FS40 / FS41 / FS42 / FS43 automatic floor stop and holder is specified for adjustable door-to-floor clearance, and a gooseneck riser such as the Delaney 40118X or Emtek 2253 brings the contact point up to the door face instead of the bottom edge.

Nine finishes on the UFBD4505: Polished Brass, PVD Polished Brass, Antique Brass, Polished Chrome, Brushed Chrome, Brushed Nickel, Antique Nickel, Oil Rubbed Bronze, and Paint Black. If you are matching hinges and levers across a building, the PVD Polished Brass is the one to pick for exterior or high traffic openings where a lacquered polished brass would eventually wear through at the dome.

Commercial. Deltana lists the UFBD4505 as a commercial grade item, and the solid brass body backs that up. For openings that take real abuse, ZenSupply also stocks heavy duty brass dome stops from Ives, the FS13 and FS17, and the FS18S/FS18L security floor stop for openings where someone might try to pry the stop off the floor.

The UFBD4505 is sold as the dome cap itself, in a single 1-5/8 inch size and one of nine finishes. If your maintenance standard is a stop whose rubber tip you can renew in place instead of pulling the anchor, spec the Ives FS13 heavy duty brass floor dome stop, which is listed with a replaceable rubber bumper. For a fleet of doors under a property management contract, that difference decides which one you standardize on.

1-5/8 inches is the size Deltana publishes for the UFBD4505, and the part is a round dome cap, so that figure is the footprint across the dome. Use it to check clearance in tight spots, a stop set behind a door in a narrow closet or against a baseboard needs that much floor. If you need a smaller footprint, the Emtek 2254 floor door bumper is listed at 1-3/8 by 1-1/4 inches and the Emtek 2257 cylindrical floor bumper at 1-1/2 inches.

Same pattern, different makers: the Delaney Dome Door Stop, the Emtek 2251 half dome door stop, and the Orca Hardware 23LP Series low rise dome floor stop are all round dome floor stops in the same family. On the heavier commercial side, Ives builds the FS13 and FS17 as heavy duty brass floor dome stops. The Deltana is the one to pick when you are matching a decorative finish across the opening, since it comes in nine, including PVD Polished Brass and Oil Rubbed Bronze.

They are both floor bumpers but they are not the same size or shape. The Deltana UFBD4505 is a round dome cap at 1-5/8 inches. The Emtek 2254 floor door bumper is listed at 1-3/8 inches by 1-1/4 inches. If you are matching an existing footprint on a floor that is already drilled, the difference in base diameter is what decides whether the new stop covers the old hole.

A dome bumper such as the Deltana UFBD4505 presents a rounded 1-5/8 inch cap the door rides onto. A cylindrical bumper such as the Emtek 2257, listed at 1-1/2 inches in the Cylinder series, presents a straight-sided post with a flat contact face. The dome shape lets the door edge glance up and over slightly; the cylinder gives a square face for the door to meet head on.

A standard dome bumper like the Deltana UFBD4505 is a general purpose floor stop. Where the stop itself has to resist tampering, the Ives FS18S/FS18L security floor stop is the purpose-built option and is a heavy duty unit. Detention, behavioral health, and other controlled openings are the usual place that distinction is called out on the drawing.

The Deltana UFBD4505 dome cap is offered in nine finishes: oil rubbed bronze, brushed nickel, antique nickel, paint black, polished chrome, brushed chrome, polished brass, antique brass, and PVD polished brass. That breadth is what lets it match existing lever and hinge finishes across a floor. The Orca Hardware 23LP dome floor stop is specified with a gray tip and the Orca 22HD goose neck with a black tip, so those carry a fixed bumper tip color rather than a finish range.

Each. The unit of measure on the UFBD4505 is one bumper, so order one per door leaf. Pairs of doors need two, and a job where you are protecting the wall behind every unit entry needs a count that matches the door schedule, not the opening count.
