Rockwood 475 Door Stop, 3-3/4" Projection, 2-1/4" Diameter Base, Plastic and Lead Anchor Fasteners

The 475 stands 3-3/4 inches tall, so that is the clearance it gives between the door face and whatever is behind it. That height matters more than it sounds: a floor stop only works if it strikes the door face, not the bottom rail or an undercut. Measure from your finished floor up the door face and confirm 3-3/4 inches lands on solid door before you set the anchor.

Mounting hardware is in the box: one 5/16-18 x 1-3/4 inch stud, an anchor, a #8 x 3/4 inch oval head sheet metal screw, and a plastic anchor. The stud and anchor are the concrete or masonry route, the sheet metal screw and plastic anchor cover wood and lighter substrates. Nothing else is required to set it, though a hammer drill and the matching bit are on you.

It carries ANSI A156.16, L02021. That is the auxiliary hardware standard, and L02021 is the type designation an architect writes into a hardware schedule for a floor stop. If your spec calls out A156.16 L02021, the 475 answers it directly. It is a commercial-grade item, not a residential accessory.

The 475 stops the door, it does not hold it. It is a fixed 3-3/4 inch post that takes the swing and stops the leaf from hitting the wall. If you need the door to stay open, that is a different part: the Ives FS40 / FS41 / FS42 / FS43 automatic floor stop and holder catches and holds the leaf, the Orca 22HD gooseneck is catalogued as a door holder, and the SOSS MDH is a magnetic holder and stop. Pick a holder when the door has to stand open for carts or airflow, and a plain stop when you only want to protect the wall.

The Ives FS13 is a heavy-duty brass floor dome stop with a replaceable rubber bumper, and the Ives FS17 is a heavy-duty brass floor dome stop with a rubber bumper. Both are dome-profile floor stops in brass like the Rockwood 475, which stands 3-3/4 inch tall on a 2-1/4 inch diameter base and meets ANSI A156.16, L02021. The FS13 differs in that its bumper is replaceable, so the stop body stays in the floor when the rubber wears through.

The Orca Hardware 23LP Series dome floor stop is a low rise dome floor stop with a gray tip and is catalogued as a door stop function. The Rockwood 475 projects 3-3/4 inch off the floor, so on a corridor or an accessible route where a tall stop is a trip hazard, the low-rise 23LP dome is the lower-profile shape. The Emtek 2254 floor door bumper at 1-3/8 inch by 1-1/4 inch and the Deltana UFBS138 square universal floor door bumper at 1-3/8 inch in solid brass are also short bumper-style units rather than tall stops.

The Rockwood 475 is a floor stop, so it arrests the door but does not hold it. For a hold-open, the Ives FS40 / FS41 / FS42 / FS43 is a heavy-duty automatic floor stop and holder with adjustable door-to-floor clearance, and the SOSS MDH is a heavy-duty magnetic door holder and stop measuring 3-5/16 inch by 1-3/4 inch. The Orca Hardware 22HD Series goose neck floor stop with black tip is catalogued with a door holder function and lists a door thickness range of 1-3/8 inch or 1-3/4 inch.

The base is 2-1/4 inches in diameter. That is the footprint you need clear on the finished floor, which is worth checking against tile joints, carpet edges, and anywhere a mop or a cart wheel has to pass. It is a single fixed post, not an adjustable holder.

Three: 613 satin bronze oil-rubbed, 619 satin nickel, and 626 satin chrome. Those are the standard BHMA finish numbers, so matching the 475 to the levers and hinges already in the building is a matter of reading the finish code off the existing hardware and ordering the same number.

They solve different problems. At 3-3/4 inches the 475 reaches up the door face, which is what you want where the door has a heavy bottom rail, an undercut, or a sweep that a short bumper would miss. A low profile dome sits close to the floor and is less of a toe catch in a corridor or a doorway people walk through constantly, which is where something like the Orca 23LP low rise dome stop or the Ives FS13 floor dome stop belongs. Traffic path decides it more than the door does.

Staying in commercial territory, the Ives FS17 and FS13 heavy duty brass floor dome stops are the nearest peers, both carried as heavy duty. The Orca 23LP is the lighter commercial dome option. Deltana's UFB series universal floor bumpers, the UFB4505 at 1-1/2 inches and the UFBD3505 at 3-1/2 inches, and Emtek's 2251 half dome and 2257 cylindrical bumper sit on the decorative and residential side. If the job is specified to A156.16 L02021, that spec is what narrows the field, and the 475 carries it.

The Rockwood 475 is a dome-style floor stop with a 2-1/4 inch diameter base and a 3-3/4 inch projection, anchored down with a 5/16-18 x 1-3/4 inch stud and anchor. A gooseneck reaches up and over on a curved arm to catch the door higher on the face: the Delaney Gooseneck Floor Door Stop, the Emtek 2253 Goose Style Door Stop, and the Orca Hardware 22HD Series goose neck floor stop with black tip are the gooseneck shape. Gooseneck is the shape to look at when the door has a large undercut or a sweep that a squat dome would pass under.

The Ives FS18S/FS18L is a security floor stop rated heavy duty, and it is the shape to look at in detention, behavioral health, or hard-use multi-family openings. The Ives FS13 and FS17 are also heavy-duty brass floor dome stops. The Rockwood 475 anchors with a 5/16-18 x 1-3/4 inch stud and anchor and carries ANSI A156.16, L02021.

For a secure opening, look at a security floor stop instead. The Ives FS18S/FS18L is the security floor stop in the range. The 475 is a standard commercial stop to A156.16 L02021 and suits offices, schools, retail, hotels, and multi-family corridors.

It works as a fleet standard where the openings are alike: one 2-1/4 inch base footprint, one 3-3/4 inch height, one A156.16 L02021 designation, and one finish code across the job. The two things that break the standard are floors that cannot take the anchor and doors whose face has nothing solid at 3-3/4 inches up. Both are worth walking before you order the quantity.

The Rockwood 475 comes in 626 satin chrome, 619 satin nickel, and 613 satin bronze oil-rubbed. If the same building needs a hold-open at some openings, the Ives FS40 / FS41 / FS42 / FS43 automatic floor stop and holder and the SOSS MDH magnetic door holder and stop cover that function, and the Ives FS13 floor dome stop keeps the same dome profile with a replaceable rubber bumper for the openings that only need a stop.
