Rockwood 446 Door Stop, Brass with Rubber Bumper

Both. The 446 ships with two fastener sets: a #12 x 1-1/2 inch wood screw with a plastic anchor for wood or for anchoring into concrete, and a #12-24 x 1 inch flat head machine screw with an anchor. So the same box covers a wood subfloor and a concrete or masonry floor without ordering separate hardware.

The 446 measures 1-1/4 x 1-1/2 inches. It is a low-rise floor stop, so it is meant for doors with normal undercut, not for a door with a large floor clearance or thick carpet. Where the door sits high off the finished floor, a gooseneck style that reaches up to the door face is the better call, like the Orca Hardware 22HD Series goose neck floor stop or the Emtek 2253 goose style stop.

Stop only. The 446 is a floor-mounted bumper with a rubber tip that catches the door and protects the wall; it does not latch the door open. For hold-open you need a stop and holder, such as the Ives FS40 / FS41 / FS42 / FS43 automatic floor stop and holder with adjustable door-to-floor clearance, or the SOSS MDH magnetic door holder and stop.

The Rockwood 446 is a brass floor stop with a rubber bumper, sized 1-1/4 inch by 1-1/2 inch. The closest peer in the same construction is the Ives FS17, a heavy-duty brass floor dome stop with a rubber bumper. The Ives FS13 is also a heavy-duty brass floor dome stop, and it uses a replaceable rubber bumper, which matters on high-traffic openings where the tip is the wear item and you want to renew it without pulling the stop off the floor. All three are floor-mounted brass stops with a resilient tip, so the choice is dome profile versus the 446 universal stop profile and whether the bumper is meant to be replaced.

The 446 is a stop only - it arrests the door swing and the door returns freely. For an opening that has to stand open, the Ives FS40, FS41, FS42 and FS43 are automatic floor stops and holders with adjustable door-to-floor clearance, which is what lets one part suit different undercuts. The Orca Hardware 22HD Series goose neck floor stop is catalogued with a door holder function and fits doors 1-3/8 inch or 1-3/4 inch thick. The SOSS MDH is a magnetic door holder and stop measuring 3-5/16 inch by 1-3/4 inch, which catches and releases the door by magnet rather than by a mechanical latch. Specify a holder wherever a door is propped daily; specify the 446 where the door should swing back on its own.

They mount the same way but catch the door at a different height. The 446 is a low universal stop 1-1/4 inch by 1-1/2 inch, so it takes the door near the bottom edge and sits close to the floor. A gooseneck rises off the floor on a curved neck and meets the door higher up, which is the answer when the door has a large undercut or a wide sweep and a low stop would pass underneath it. Gooseneck options include the Delaney Gooseneck Floor Door Stop, the Emtek 2253 Goose Style Door Stop, and the Orca Hardware 22HD Series goose neck floor stop with a black tip, which fits 1-3/8 inch or 1-3/4 inch doors. A taller stop stands proud of the floor, so it is more of a trip and mop obstruction in a corridor than the 446 profile.

Five: 605 bright brass, 606 satin brass, 613 satin bronze oil-rubbed, 626 satin chrome, and 630 satin stainless steel. Those are standard BHMA finish codes, so if the levers and hinges on your other openings are specified 626 or 630, the stop matches them without eyeballing it.

Yes. The rubber bumper on the 446 comes in standard gray, with black available as an option. Gray is what ships unless black is specified, so call it out on the order if you are matching dark flooring or a black hardware package.

Commercial. The 446 is a brass stop with a rubber bumper built for institutional and commercial openings: offices, schools, retail, detention, sports facilities, hotels and restaurants. Brass body rather than a plated zinc casting is what carries it through repeated daily strikes in a public corridor.

No handing. The 446 is a universal stop, so the same part goes on a left or right hand door and on either side of a pair. For a property manager standardizing a building, that means one SKU per finish covers every opening instead of stocking a left and a right.

Not the strongest option for that. The 446 is a standard commercial floor stop. Where the concern is tampering or abuse, the Ives FS18S/FS18L security floor stop is the heavy-duty part built for it.

No. Mounting hardware is included with the 446: a #12 x 1-1/2 inch wood screw with plastic anchor and a #12-24 x 1 inch flat head machine screw with anchor. The only thing you supply is the drill and the correct bit for your floor material.

The 446 measures 1-1/4 inch by 1-1/2 inch. The Emtek 2254 floor door bumper is 1-3/8 inch by 1-1/4 inch, the nearest match in footprint. The Deltana UFB4505 is a round universal floor door bumper at 1-1/2 inch in solid brass, and the Deltana UFBS138 is a square universal floor door bumper at 1-3/8 inch in solid brass, so the same opening can be done in a round or square cap. The Emtek 2257 is a 1-1/2 inch cylindrical floor bumper, which is a straight-sided column rather than a domed cap. Where a stop is being swapped in an existing floor, the diameter decides whether it covers the old anchor hole.

The 446 is a commercial brass stop with a rubber bumper, suited to institutional buildings, offices, retail, educational, detention, sports facilities, hotel and restaurant work. Where the stop itself is a target, the Ives FS18S and FS18L are heavy-duty security floor stops built for that condition. The Ives FS13 is a heavy-duty brass floor dome stop with a replaceable rubber bumper, which is the practical choice where tips get chewed up and the maintenance crew wants to renew the bumper rather than replace the whole stop. Both are heavy duty, so the decision is whether the exposure is abuse of the stop body or wear on the tip.

They do the same job but are not the same shape. The 446 is a modern style universal stop measuring 1-1/4 inch by 1-1/2 inch. Dome stops present a rounded half-sphere cap: the Delaney Dome Door Stop, the Emtek 2251 Half Dome Door Stop, the Deltana UFBD3505 round universal floor bumper at 3-1/2 inch in a decorative solid brass profile, and the Orca Hardware 23LP Series low rise dome floor stop with a gray tip, which is catalogued with a door stop function. The Deltana UFBD3505 at 3-1/2 inch covers far more floor than the 446, so it reads as a decorative element rather than a discreet one. For a fleet of doors that should all look alike, match the cap profile across the building rather than assuming any floor stop drops in for another.

Both are solid brass floor bumpers. The Rockwood 446 is a modern style universal stop 1-1/4 inch by 1-1/2 inch, available in 605 bright brass, 606 satin brass, 613 satin bronze oil-rubbed, 626 satin chrome and 630 satin stainless steel, so it can be matched to the lever and hinge finish already specified. The Deltana UFBP4505 is a round universal floor door bumper with a pattern cap at 1-5/8 inch, and the Deltana UFBD3505 is a decorative round floor bumper at 3-1/2 inch, both in solid brass. The Deltana parts put a decorative face on the floor; the 446 keeps a plain cap and carries the finish match across the schedule.

The Rockwood 446 ships with a #12 x 1-1/2 inch wood screw and plastic anchor plus a #12-24 x 1 inch flat head machine screw and anchor, so it covers both a wood subfloor and a drilled anchor in concrete or masonry without ordering fasteners separately. That is a floor-anchored fixing in either case. Where drilling the slab is not an option - a polished terrazzo lobby, a post-tension deck, a floor the owner will not let you core - the SOSS MDH magnetic door holder and stop at 3-5/16 inch by 1-3/4 inch and the Ives FS40, FS41, FS42 and FS43 automatic floor stop and holder change the approach at the opening. Confirm the floor construction before the stop is specified, because that decision is made once per building.

The 446 works fine residentially, it is just specified for commercial duty. If you want a lighter or more decorative solid brass bumper for a residence, the Deltana UFB4505 round universal floor bumper at 1-1/2 inches, the square UFBS138 at 1-3/8 inches, or the decorative UFBD3505 at 3-1/2 inches are solid brass alternatives.
