Rockwood 441 Low Dome Stop

Stop only. The 441 is a fixed cast brass dome with a rubber bumper: it absorbs the swing and keeps the door off the wall, but there is no catch, no hook, and no magnet, so the door swings back freely. If the door needs to stay open, look at the Ives FS40 / FS41 / FS42 / FS43 automatic floor stop and holder, the SOSS MDH magnetic door holder and stop, or the Orca 22HD Series gooseneck, which is listed as a door holder rather than a stop.

The Rockwood 441 stops the door and lets it swing back. When the door has to stand open, move to a holder. The Ives FS40, FS41, FS42 and FS43 are automatic floor stops and holders with adjustable door-to-floor clearance, so one device both stops and catches the door. The Orca Hardware 22HD Series goose neck floor stop is catalogued with a door holder function, and Emtek builds the 2253 in a goose style. The SOSS MDH is a magnetic door holder and stop at 3-5/16 by 1-3/4 inches for openings where a magnet is preferred to a mechanical catch. Delaney's Gooseneck Door Stop series covers the same upright shape.

Yes, it is a commercial specification item built to ANSI A156.16 and carrying the type number L02141 under that standard, which is the auxiliary hardware standard floor stops are graded against. The body is solid cast brass with a rubber bumper doing the impact work, which is why it turns up in schools, healthcare, hotels, offices, and detention work rather than as a builder-grade stamped stop.

Add the EXP suffix to the order. That substitutes the exterior screw pack, stainless steel plated to match the finish of the stop, in place of the standard fasteners. Worth doing anywhere the stop sees weather or washdown, since the screw heads sit exposed in the floor and are the first thing to corrode.

The Rockwood 441 rises 7/32 inch above the floor and spreads that over a 1-7/8 inch diameter, so it is a wide shallow dome rather than an obstruction. That profile is the reason it gets specified in traffic areas and in front of carted openings, where a gooseneck standing up off the floor sits directly in the walking path. The trade-off is that the door has to reach the floor to hit it, so it will not serve an undercut door.

Staying with the same low dome format, the Ives FS13 and FS17 are heavy duty brass floor dome stops with rubber bumpers, and the FS13 is listed with a replaceable rubber bumper if you want a stop you can service instead of replace. The Orca Hardware 23LP Series is a low rise dome floor stop with a gray tip. Delaney also makes a dome door stop. If the look matters more than the format, the Deltana UFB4505 is a 1-1/2 inch round solid brass floor bumper and the UFBD3505 a 3-1/2 inch decorative version. All of them share the 441's basic limitation: the door has to come down to the floor to reach them.

Several round floor bumpers share the 441 footprint without doing the same job. The Deltana UFB4505 at 1-1/2 inch, the UFBP4505 pattern cap at 1-5/8 inch, the Emtek 2254 floor door bumper at 1-3/8 by 1-1/4 inches, and the Emtek 2257 cylindrical floor bumper at 1-1/2 inch are universal floor bumpers, so confirm the standing height suits your door bottom before swapping one in for the 441's 7/32 inch dome. The SOSS MDH is a different device again: it is a magnetic door holder and stop, so it catches and retains the door rather than only stopping it. The Ives FS40 through FS43 family is likewise a floor stop and holder, not a plain stop.

The Rockwood 441 is a solid cast brass stop with a rubber bumper. Among the brass dome stops, the Ives FS13 is built as a heavy-duty brass floor dome stop with a replaceable rubber bumper, which is the one to standardize on if your crews want to change the tip in place. The Ives FS17 is the companion heavy-duty brass floor dome stop with a rubber bumper. Both keep the same low brass dome shape as the 441, so the look across a facility stays consistent.

The Rockwood 441 is a commercial solid brass dome stop carrying ANSI A156.16, L02141, which is more device than a light-duty interior door usually needs. For a plainer round bumper, Deltana offers the UFB4505 universal floor door bumper at 1-1/2 inch and the UFBS138 square universal floor door bumper at 1-3/8 inch, both solid brass. Emtek's 2251 half dome door stop and 2254 floor door bumper at 1-3/8 by 1-1/4 inches cover the same duty. Delaney's Dome Stop series is another simple round option.

Four architectural finishes are offered on the 441: 605 bright brass, 612 satin bronze, 613 oil rubbed bronze, and 626 satin chrome. Those are standard BHMA finish numbers, so a 626 stop lines up with 626 hinges, levers, and pulls elsewhere in the opening, and 613 matches oil rubbed bronze trim. Handy when you are standardizing stops across a floor or a whole building and want one part number in four looks.

The 441 is a standard commercial dome stop, cast brass to ANSI A156.16 type L02141, and it suits offices, schools, hotels, and retail. For an opening where the stop itself is a target, the Ives FS18S/FS18L security floor stop is the heavy duty option built for that duty. Either way, both are floor-mounted, so the door still has to reach the floor: an undercut door or a threshold in the swing path rules out the dome format entirely.

The Rockwood 441 is a plain low brass dome, supplied in 605 bright brass, 612 satin bronze, 613 oil rubbed bronze and 626 satin chrome. If the client wants ornament, Deltana builds the UFBD3505 as a 3-1/2 inch decorative round universal floor bumper in solid brass and the UFBP4505 as a 1-5/8 inch round bumper with a pattern cap. Emtek's 2251 half dome and 2257 cylindrical floor bumper at 1-1/2 inch come out of its door accessories range for a matched residential look.
