Deltana UFBD3505 Round Universal Floor Bumper 3-1/2", Decorative, Solid Brass

Height is what decides that, and the Deltana UFBD3505 stands 3-1/2 inches tall, so it catches the door well up the face rather than down at the rail. Measure from your finished floor to the point on the door where you want contact, then check that the bumper sits under that point. If your lever or the door's backplate projects further than the bumper's standoff, you want a wall stop or a gooseneck floor stop instead, like the Orca Hardware 22HD Series goose neck floor stop, which reaches out from the floor to catch a door swinging past a fixed floor position.

Deltana lists the UFBD3505 as commercial, and the solid brass construction is the reason it carries that. For a decorative opening in a hotel lobby, a multi-family corridor or a class A office suite it holds up. For a back-of-house or high-abuse opening where the stop gets kicked daily, a purpose-built heavy duty stop is the better spec, such as the Ives FS13 or FS17 brass floor dome stops, both listed heavy duty and both with a replaceable rubber bumper so you renew the wear part instead of the whole stop.

It stops, it does not hold. The UFBD3505 is a floor bumper, so the door rests against it and swings back freely. If you need the door to stay open, that is a different part: the Ives FS40, FS41, FS42 and FS43 are automatic floor stops and holders with adjustable door-to-floor clearance, and the SOSS MDH is a magnetic door holder and stop measuring 3-5/16 by 1-3/4 inches. Ordering a bumper when the spec calls for a holder is one of the more common returns on this category.

Watch the clearance. A floor bumper only works if the door's bottom edge clears the top of the stop as it swings, and at 3-1/2 inches the UFBD3505 is a tall one. Over thick carpet or with a large undercut for return air, the door bottom can foul the bumper before it reaches the intended stopping point. Where the door-to-floor gap is the variable, the Ives FS40 through FS43 automatic floor stops are made with adjustable door-to-floor clearance for exactly that condition.

The Deltana UFBD3505 is a 3-1/2 inch round universal floor bumper in solid brass. If a 3-1/2 inch projection stands too tall for the door-to-floor gap, the Emtek 2257 is a 1-1/2 inch cylindrical floor bumper, and the Emtek 2254 floor door bumper measures 1-3/8 inch by 1-1/4 inch. Both keep the same simple round floor-mounted form in a much shorter body.

The Deltana UFBD3505 is a solid brass decorative floor bumper carried for commercial use. Where the spec calls for a stated duty level, the Ives FS13 and FS17 are heavy-duty brass floor dome stops with rubber bumpers - the FS13 bumper is replaceable, which matters on openings where the tip is the wear item - and the Ives FS18S and FS18L are heavy-duty security floor stops.

Solid brass, both the body and the substrate, which is why it takes plated and lacquered finishes like polished nickel and antique brass rather than a painted coating. That matters on a floor-mounted part getting kicked and mopped: a plated pot metal stop chips at the base, brass takes the abuse and the finish wears rather than flakes. The one exception in the finish range is Paint Black, which is a coating over the same brass body.

Twelve finishes: oil rubbed bronze, polished nickel, brushed nickel, antique nickel, paint black, polished chrome, brushed chrome, polished brass, unlacquered brass, brushed brass, antique brass, and PVD polished brass. That range covers the standard Deltana finish palette, so a property manager standardizing a building can pull the bumper in the same finish as the levers, hinges and rosettes already on the openings. Two worth calling out: unlacquered brass will patina over time and is chosen deliberately for that, and PVD polished brass is the finish to specify where the stop takes heavy cleaning and you do not want the brass to dull.

Height and where the door makes contact. At 3-1/2 inches the UFBD3505 is a tall cylindrical bumper that meets the door up on its face, which keeps the contact point away from the bottom rail and out of the mop path. A low dome stop, like the Orca Hardware 23LP Series low rise dome floor stop or the Emtek 2251 half dome, sits close to the floor and catches the very bottom of the door. Low domes are less of a toe hazard in a walkway and less visible; tall bumpers keep hardware off the wall on doors where the lever or a pull projects. Pick by where your door needs to be caught, not by looks.

Handing does not apply. The UFBD3505 is a round floor bumper that mounts to the floor in the door's swing path, so the same part serves a left hand or right hand opening, a single door or both leaves of a pair. What you do have to decide per opening is where on the floor it lands, which is set by how far you want the door to travel before it stops.

Not as a drop-in. Floor stops from different makers use their own base diameter and fastener location, so swapping a Delaney dome stop or an Emtek 2254 floor door bumper for the Deltana leaves the old hole in a spot the new base may not cover. If the existing stop is a low dome and you are moving to the 3-1/2 inch Deltana, expect to relocate the fixing anyway, because the taller bumper contacts the door higher and usually wants a different position on the floor. Plan on patching the old hole in a finished floor.

The Deltana UFBD3505 is a round universal floor bumper in a 3-1/2 inch decorative profile. For a dome form, the Delaney Dome Door Stop and the Emtek 2251 Half Dome Door Stop cover the residential-style dome shape, the Ives FS13 and FS17 are heavy-duty brass floor dome stops with rubber bumpers, and the Orca Hardware 23LP Series is a low-rise dome floor stop with a gray tip listed as a door stop.

They are not the same device. The Deltana UFBD3505 is a solid brass floor bumper that stops the door on contact. The SOSS MDH is a magnetic door holder and stop at 3-5/16 inch by 1-3/4 inch, so it catches and retains the door magnetically and requires a mating strike on the door rather than a bare door edge. If the requirement is simply to protect the wall, the UFBD3505 does that; if the door must stay open on its own, the MDH is the function being asked for.

The Deltana UFBD3505 comes in Oil Rubbed Bronze, Polished Nickel, Brushed Nickel, Antique Nickel, Paint Black, Polished Chrome, Brushed Chrome, Polished Brass, Unlacquered Brass, Brushed Brass, Antique Brass and PVD Polished Brass, all on a solid brass body, which is the widest decorative spread among the round floor bumpers. The Emtek 2251 Half Dome and Emtek 2257 cylindrical bumper sit in the same decorative-collection category if the property standard is Emtek. Where the opening is back-of-house rather than front-of-house, the Ives FS13 and FS17 heavy-duty brass dome stops and the Orca 23LP with a gray tip are the functional choices.

The bumper fastens to the floor, so the fixing has to suit the substrate. On wood or plywood subfloor the supplied screw goes straight in. On tile, stone or concrete you drill and set an anchor, and you should not fasten through a tile without a masonry bit and a plug, or the tile cracks. Order the anchors with it. One more check before you drill: know what is under the slab or in the joist bay, because a floor stop lands in the exact spot where in-floor heat and conduit tend to run.

The UFBD3505 is the 3-1/2 inch round universal floor bumper, and it is one model within Deltana's UFBD Series of universal floor bumpers. For a building standard, the practical approach is to fix on one height and one finish across all openings that share the same door and wall condition, then use a different type only where the condition changes, for example a holder at doors that must stay open. Buying a single model and finish across a fleet also keeps a small spares stock viable.
