Rockwood 482 Door Stop, 2-1/8" Projection, 1-1/2" by 2-1/2" Base, Plastic and Lead Anchor Fasteners

The 482 ships with fasteners for both. You get a 5/16-18 x 1-3/4 inch stud with an anchor for masonry or concrete, and a #12 x 1-1/4 inch flat head wood screw with a plastic anchor for wood or lighter substrates. So one part number covers a poured slab in a corridor and a wood-framed unit, no separate anchor order needed.

Projection off the floor is 2-1/8 inches, on a base measuring 1-1/2 x 2-1/2 inches. That height is what lets the bumper catch the door face rather than the bottom rail, but it also means the door bottom has to clear 2-1/8 inches of stop where it swings over it. On an opening with a low undercut or a floor closer arm in the way, measure the door-to-floor clearance at the stop location first.

It carries ANSI A156.16, type L02131, and is a commercial-duty stop. That is the BHMA standard covering auxiliary door hardware, so it is the citation to put on a submittal for an institutional or government spec that calls for A156.16 stops. Body is solid cast brass with a rubber bumper.

Yes. The 482 uses replacement bumper 461B, so when the rubber flattens or tears you swap the tip and leave the cast brass base and anchor in the floor. That matters on a fleet of doors, since a facility can stock 461B bumpers and never disturb the floor anchors again.

For outdoor openings order it as 482 x EXP. The EXP suffix substitutes an exterior screw pack, stainless steel plated to match the finish, in place of the standard fasteners. If you are setting a stop at an exterior vestibule, loading dock, or anywhere it takes weather and washdown, specify the suffix on the order line, since the base part ships with the standard pack.

The 482 is a stop only. It arrests the swing and protects the wall, but it will not retain the door in the open position. If you need the door to stay open, that is a different part: the Orca Hardware 22HD Series goose neck floor stop is catalogued as a door holder, and the Ives FS40 / FS41 / FS42 / FS43 is an automatic floor stop and holder with adjustable door-to-floor clearance. A magnetic option, the SOSS MDH, holds and stops at 3-5/16 x 1-3/4 inches. Just be aware that holding a fire door open with mechanical hardware is not permitted, so confirm the opening is not fire rated before you go that route.

The closest cross-brand match is the Ives FS13 heavy-duty brass floor dome stop with replaceable rubber bumper, which is the same idea: cast brass body, heavy duty, and a bumper you can change out rather than replacing the whole stop. The Ives FS17 is also a heavy-duty brass floor dome stop with a rubber bumper. Both come from the same segment as the 482, which is a commercial cast brass stop with a 2-1/8 inch projection.

Go to a low rise dome. The Orca Hardware 23LP Series is a low rise dome floor stop with a gray tip, made for exactly this problem. Among the solid brass round bumpers, the Deltana UFBS138 square universal floor bumper is 1-3/8 inches and the Deltana UFB4505 round universal floor bumper is 1-1/2 inches, both under the 482's 2-1/8 inches. The trade-off is contact point: a shorter bumper strikes lower on the door face, which is fine on a flush door but can miss the rail on a stile-and-rail door.

The Ives FS13 is the nearest match. Like the 482, it is a heavy duty brass floor dome stop with a replaceable rubber bumper, so a worn tip can be swapped without pulling the base off the floor. The 482 uses replacement bumper 461B and is rated to ANSI A156.16, L02131, with a 1-1/2 inch by 2-1/2 inch base and 2-1/8 inch height. The Ives FS17 is the same heavy duty brass floor dome stop family but is described with a rubber bumper rather than a replaceable one, so specify the FS13 when field-replaceable tips matter on a maintenance contract.

Move to a gooseneck style stop, which raises the bumper on an arm so it catches the door face further in from the edge. The Ives FS40, FS41, FS42 and FS43 are automatic floor stops and holders with adjustable door to floor clearance, which also handles an uneven or carpeted floor. The Orca Hardware 22HD Series goose neck floor stop with black tip suits 1-3/8 inch or 1-3/4 inch doors and functions as a door holder rather than a plain stop. Emtek 2253 and the Delaney Gooseneck are the same goose profile in lighter residential trim. The Rockwood 482 stands 2-1/8 inch tall on a 1-1/2 inch by 2-1/2 inch base, so it only works where the door face reaches a point within that height.

The Rockwood 482 is a stop only, so pick a holder. 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 and keeps it open until it is pulled free. The Ives FS40, FS41, FS42 and FS43 are automatic floor stops and holders with adjustable door to floor clearance, using a mechanical catch you release with a toe. The Orca Hardware 22HD Series is listed as a door holder on a goose neck body for 1-3/8 inch or 1-3/4 inch doors. All three occupy more floor than the 482, which sits on a 1-1/2 inch by 2-1/2 inch base.

Specify the Ives FS18S or FS18L security floor stop, a heavy duty unit built for openings where a standard dome can be pried or removed. The Rockwood 482 is a commercial cast brass stop mounted with a 5/16-18 by 1-3/4 inch stud and anchor or a #12 by 1-1/4 inch flat head wood screw with plastic anchor, which is right for offices, retail, education and hospitality but is not a security rated stop. Check whether the specification calls the short FS18S or the long FS18L before ordering.

Three: 606 satin brass, 613 satin bronze oil-rubbed, and 626 satin chrome. Match 626 to satin chrome or brushed nickel lever trim, 613 to oil-rubbed bronze on a residential or hospitality opening, and 606 to satin brass. Those are the three standard architectural finishes offered on the 482.

That is what it is built for. Solid cast brass body, commercial duty, and Rockwood calls it heavy duty for use on heavy doors or in high traffic areas. On a school corridor, hospital wing, or hotel guest floor where the stop takes a strike hundreds of times a day, the replaceable 461B bumper is the wear item rather than the stop itself. Lighter decorative bumpers, like the Emtek 2254 floor bumper at 1-3/8 x 1-1/4 inches, are aimed at residential openings instead.

Use a floor stop when there is no solid wall behind the door swing, when the wall is glass or a stud bay you cannot reliably block, or when the door swings back past a wall entirely. The 482 sets in the floor at 2-1/8 inches of projection on a 1-1/2 x 2-1/2 inch base, so it needs a floor you can anchor into and it does become a trip and mop-strike point in a walking path. A wall stop keeps the floor clear but only works where the blocking behind the drywall is real. On a corridor door in an institutional building, a floor stop is usually the safer bet because the door face contact is fixed and does not depend on wall construction.

It works well as a fleet standard. One model covers wood and concrete floors out of the box because both anchor types are in the fastener pack, exterior openings are handled with the 482 x EXP suffix, and the three finishes (606, 613, 626) cover most trim schedules. Long term you carry one spare part, the 461B bumper, instead of a shelf of complete stops. Just hold the projection consistent at 2-1/8 inches so door undercuts match across the building.

The Orca Hardware 23LP Series is a low rise dome floor stop with a gray tip and is listed as a door stop function, which puts the strike point closer to the floor than the Rockwood 482 and its 2-1/8 inch height. The Emtek 2254 floor door bumper measures 1-3/8 inch by 1-1/4 inch and the Emtek 2251 is a half dome door stop, both squat profiles. Confirm the undercut on the door leaf before choosing, since a low rise stop must still contact the door face rather than pass under it.

The Deltana UFBD3505 is a round universal floor bumper 3-1/2 inch in solid brass in a decorative style, and the UFBP4505 is a 1-5/8 inch round bumper with a pattern cap. The Emtek 2257 is a 1-1/2 inch cylindrical floor bumper from the Emtek door accessories collection, and the Delaney Dome Stop is a dome profile. The Rockwood 482 is a commercial cast brass dome with a rubber bumper in 613 satin bronze oil rubbed, 626 satin chrome and 606 satin brass, so it will read as institutional trim next to those decorative caps.

The Rockwood 482 carries ANSI A156.16, L02131 and takes replacement bumper 461B, with an EXP suffix ordering option for stainless steel plated exterior pack screws on exterior openings. The Ives FS13 is a heavy duty brass floor dome stop with a replaceable rubber bumper, the FS17 is a heavy duty brass floor dome stop with a rubber bumper, the FS18S and FS18L are heavy duty security floor stops, and the FS40 through FS43 are heavy duty automatic stops and holders. Standardizing on one family keeps a single replacement tip in the maintenance stock rather than several.

Both. The rubber bumper is standard gray, with black available as an option. Gray is what most people order against a light floor; black hides scuffing and reads better under a dark base or dark tile. Specify which one you want on the order.
