Rockwood 472 Door Stop with Keeper, 3-3/4" Height, 2-1/2" Diameter Base, Plastic Anchor Fasteners

A plain floor stop only cushions the door and stops swing. The Rockwood 472 adds a keeper, a separate 1 inch wide by 1-3/4 inch high plate that mounts on the door bottom and catches on the stop so the door is held open until you pull it free. That is what you want on a corridor or entry door that has to stand open for carts, deliveries, or ventilation. If you only need to protect the wall and the door, a straight dome or bumper stop is the simpler buy.

The 472 stands 3-3/4 inches tall on a 2-1/2 inch diameter base. That height is what lets the keeper on the door bottom engage the stop, so the undercut at the door has to be tight enough that the door bottom meets the stop body rather than passing over it. On openings with a large floor-to-door gap, an adjustable-height unit such as the Ives FS40 / FS41 / FS42 / FS43 automatic floor stop and holder is set up for varying door-to-floor clearance.

It is a commercial-grade stop, certified to ANSI A156.16 under type number L01361. That is the standard MRO and institutional specs cite for auxiliary door hardware, so it drops into a facility spec without a substitution request. The body is cast brass with a rubber bumper, not zinc or plastic.

Yes, but order it with the EXP suffix. Rockwood offers an exterior pack screw pack, stainless steel plated to match the finish, and you call it out as 472 x EXP on the order. The standard pack ships with plain wood screws and plastic anchors, which is what you want inside and not what you want in weather.

The Ives FS17 is the nearest straight equivalent: a heavy-duty brass floor dome stop with a rubber bumper, the same basic dome-on-a-base form as the cast brass Rockwood 472 with rubber bumper. The Ives FS13 is the same heavy-duty brass floor dome stop with a replaceable rubber bumper, so if a facility wants to swap a worn tip rather than pull the whole stop off the floor, the FS13 is the one to specify. Note that the Rockwood 472 ships with a keeper, 1 inch wide by 1-3/4 inch high, which lets the door be held open against the stop; a plain FS13 or FS17 dome stop is a stop only and will not hold the door.

The Rockwood 472 does the hold with a separate keeper, 1 inch wide by 1-3/4 inch high, mounted to the door so it catches on the stop. Two other approaches: the Ives FS40, FS41, FS42 and FS43 are heavy-duty automatic floor stops and holders with adjustable door-to-floor clearance, so the hold is built into the stop and you set it to the gap under the leaf rather than fitting a second piece to the door. The SOSS MDH is a heavy-duty magnetic door holder and stop measuring 3-5/16 inch by 1-3/4 inch, which catches the door magnetically instead of mechanically. Orca Hardware's 22HD Series goose neck floor stop is listed as a door holder for doors 1-3/8 inch or 1-3/4 inch thick.

The Rockwood 472 is 3-3/4 inches high on a 2-1/2 inch diameter base, which is the height you need when the door has to be stopped well above the floor. For a low silhouette, the Orca Hardware 23LP Series is a low rise dome floor stop with a gray tip, and the Deltana UFB Series UFB4505 is a 1-1/2 inch round universal floor door bumper in solid brass. Emtek's 2254 floor door bumper measures 1-3/8 inch by 1-1/4 inch, and the 2257 is a 1-1/2 inch cylindrical floor bumper. A bumper of that height contacts the door low on the leaf, so confirm the door bottom clears it and that there is no sweep or shoe in the way.

Drop the keeper and go to a plain floor dome or bumper. The Ives FS13 and FS17 heavy-duty brass floor dome stops with rubber bumpers are the closest commercial equivalents in cast brass. On lighter residential work, the Deltana UFB4505 solid brass round universal floor bumper at 1-1/2 inches or the Emtek 2254 floor door bumper at 1-3/8 by 1-1/4 inches sit much lower to the floor. Those all stop the door; none of them hold it open.

A few options that hold rather than just stop. A gooseneck stop mounts to the floor and reaches up to the door face instead of relying on a keeper: the Orca Hardware 22HD Series goose neck floor stop is listed as a door holder for 1-3/8 or 1-3/4 inch doors, and the Delaney gooseneck and Emtek 2253 goose style stops are the same idea. If you want nothing standing proud of the floor, the SOSS MDH is a magnetic door holder and stop measuring 3-5/16 by 1-3/4 inches. The 472 approach, a 2-1/2 inch diameter base with a keeper on the door, is the one that keeps the trip hazard lowest at the floor.

The Rockwood 472 is a commercial cast brass stop certified to ANSI A156.16, L01361, which is the reference an institutional spec is usually written against. Where the concern is abuse or pry attack rather than duty rating, the Ives FS18S and FS18L are security floor stops in Ives' heavy-duty line, built for openings where a standard dome stop gets attacked. The Ives FS13 heavy-duty brass floor dome stop with a replaceable rubber bumper is the other institutional answer, since maintenance can renew the tip on a high-traffic door without redrilling the floor.

They are not interchangeable. The Rockwood 472 is a cast brass floor stop, 3-3/4 inches tall on a 2-1/2 inch base, with a rubber bumper and a keeper for holding the door. The Deltana UFB4505 at 1-1/2 inches, the UFBP4505 pattern cap bumper at 1-5/8 inches, the square UFBS138 at 1-3/8 inches and the Emtek 2254 at 1-3/8 inch by 1-1/4 inch are floor bumpers: low pucks that cushion the leaf where it lands, with no keeper and no hold-open. If the drawing calls for a stop that arrests the door and holds it, a bumper will not satisfy it. If all you need is to keep the knob off the drywall at a door that already swings to a hard limit, the bumper is the simpler part.

The Rockwood 472 mounts on the floor directly under the door's arc and stands 3-3/4 inches high on a 2-1/2 inch base, so it needs floor at the stop point. Where the door swings over carpet, a threshold or a floor you cannot drill in the right spot, a gooseneck reaches out from the baseboard instead: 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, which is listed for 1-3/8 inch or 1-3/4 inch doors and functions as a door holder. Gooseneck stops take the impact into the wall framing rather than the slab, so check that you are landing in solid backing.

No. The 472 is a stop-and-keeper set, and the fastener pack includes hardware for both pieces: three screws and anchors for the stop plus two screws and anchors for the keeper. One order number covers the floor unit and the door plate.
