Rockwood 440 Floor Door Dome Stop

Each 440 ships with a #12 x 1-1/4 inch flat head wood screw and a plastic anchor. The anchor is what makes it work in concrete or masonry: drill for the anchor, set it, and drive the #12. Into a wood subfloor you can skip the anchor and run the screw straight in. Nothing else is required to mount it.

Order it as 440 x EXP. The EXP suffix substitutes the exterior screw pack, stainless steel plated to match the finish, instead of the standard fastener. Torx fasteners are also available as an option if you want a tamper-resistant head on a public-facing opening.

The 440 carries ANSI A156.16 type number L02141. That is the standard for auxiliary door hardware, and the L02141 designation is what you cite on a hardware schedule when the spec calls for a floor-mounted dome stop.

A dome stop like the 440 sits low on the floor at 1-1/8 inches and catches the bottom of the door face, which suits doors that sit close to the floor and openings where you don't want anything to trip over. A gooseneck rises higher and reaches up to catch the door when there's too much floor clearance for a dome to make contact. On the gooseneck side we carry the Delaney gooseneck floor door stop, the Emtek 2253 goose style, and the Orca 22HD gooseneck.

If the gap between the bottom of the door and the finished floor is more than 1-1/8 inches, the 440 won't make contact and you need a taller bumper or a gooseneck. Taller round floor bumpers we carry include the Deltana UFBD3505 at 3-1/2 inches and the Emtek 2257 cylindrical floor bumper at 1-1/2 inches. For a good deal of clearance, go to a gooseneck such as the Orca 22HD or the Emtek 2253.

The Rockwood 440 dome stop is intended for doors without thresholds and not undercut, so a low dome sitting on the floor will not reach a door with clearance beneath it. For that opening, use a riser-style stop: the Ives FS40, FS41, FS42 and FS43 automatic floor stop and holder is built around adjustable door-to-floor clearance, and gooseneck stops such as the Orca Hardware 22HD Series goose neck floor stop with black tip or the Emtek 2253 goose style door stop carry the bumper up off the floor on a neck. The Orca 22HD is specified for 1-3/8 inch or 1-3/4 inch doors and functions as a door holder as well as a stop.

The 440 is a dome stop; it arrests the door and lets it swing back. To hold the leaf open, the Ives FS40, FS41, FS42 and FS43 are an automatic floor stop and holder, and the Orca Hardware 22HD Series gooseneck is specified as a door holder. The SOSS MDH is a heavy-duty magnetic door holder and stop measuring 3-5/16 inches by 1-3/4 inches, which catches and retains the door magnetically instead of by a mechanical arm. On a fleet of units where residents prop doors with wedges, one of these holders replaces the wedge; a plain dome stop will not.

The Ives FS17 is the closest match - a heavy-duty brass floor dome stop with a rubber bumper, the same dome-on-the-floor arrangement as the Rockwood 440 solid cast brass dome stop with rubber bumper. If you want the bumper to be serviceable rather than replacing the whole stop, the Ives FS13 is a heavy-duty brass floor dome stop with a replaceable rubber bumper. All three are floor-mounted domes for doors that swing over an uninterrupted floor.

Solid cast brass body with a rubber bumper. The brass casting is the part that takes the abuse over the life of the opening; the rubber is the contact face that absorbs the door. For a stop where the bumper itself is a replaceable service part, the Ives FS13 heavy-duty brass floor dome stop is listed with a replaceable rubber bumper.

Eight finishes: 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil rubbed bronze, 613E oil rubbed bronze equivalent, 619 satin nickel, 625 bright chrome, and 626 satin chrome. If you're standardizing a building, 626 satin chrome and 630-family hardware are the usual commercial default, and 613E is the plated equivalent to use when you want the oil rubbed look without the living finish.

The 440 is commercial hardware, cast brass rather than stamped, and it carries the ANSI A156.16 L02141 type number that a commercial hardware schedule calls for. For higher-traffic or abuse-prone openings, the Ives FS13 and FS17 brass floor dome stops are both rated heavy duty, and the Ives FS18S/FS18L is a security floor stop for openings where the stop itself gets attacked.

Both are brass floor dome stops, so functionally they do the same job, but they don't share a mounting footprint on record. The 440 mounts on a single #12 x 1-1/4 inch flat head screw with a plastic anchor, and its base is 1-7/8 inches in diameter. Pull one existing stop, check that the old hole lines up with a #12 and that the 1-7/8 inch base covers any patched floor, and the changeover is a one-screw job per door.

For a flatter footprint than the 440's 1-1/8 inch dome, the Orca 23LP dome floor stop is a low rise version with a gray tip, and the Deltana UFBS138 is a 1-3/8 inch square universal floor bumper. The Deltana UFB4505 round universal floor bumper at 1-1/2 inches is another compact option. Just verify the door clears whichever one you pick, since a lower stop needs the door to hang lower to make contact.

The Ives FS18S and FS18L are heavy-duty security floor stops, built for openings where the stop itself is a target - detention-adjacent spaces, schools, transit, anywhere hardware gets attacked. The Rockwood 440 is a standard solid cast brass dome stop and is offered with an Exterior Pack of stainless steel plated screws, ordered as 440 x EXP, and with Torx fasteners, which addresses corrosion and casual removal rather than deliberate attack.

The Rockwood 440 is a commercial-grade solid cast brass dome stop carrying ANSI A156.16 number L02141, which is the reference a facility specification can be written against, and it comes in eight finishes so one part number covers different hardware schedules across a building. The Delaney Gooseneck Door Stop and the Delaney Dome Door Stop are the neck and dome forms in that brand's line. If you are standardizing a portfolio and your spec cites A156.16 L-numbers, the 440 is the one that answers it directly.

No. The 440 is a symmetrical dome on a round 1-7/8 inch base with one center fastener, so there's no left or right hand version. You only choose finish, and whether you want the EXP exterior screw pack or Torx fasteners. Placement is what you decide in the field: set it where the door face lands at the open angle you want.

The Rockwood 440 is a plain solid cast brass dome available in bright brass, satin brass, satin bronze, oil rubbed bronze, oil rubbed bronze equivalent, bright chrome, satin chrome and satin nickel. For a more ornamental floor stop, the Deltana UFBD3505 is a 3-1/2 inch round universal floor bumper described as decorative in solid brass, and the Deltana UFBP4505 is a 1-5/8 inch round universal floor door bumper with a pattern cap in solid brass. The Delaney Dome Door Stop is another dome-series option in a residential-leaning line.

The Emtek 2257 is a 1-1/2 inch cylindrical floor bumper, a straight-sided post, while the Rockwood 440 is a dome with a 1-7/8 inch diameter base rising to 1-1/8 inches, so the 440 sheds a foot rather than catching a square edge. The 440 fastens with a #12 x 1-1/4 inch flat head wood screw and plastic anchor and is meant for doors without thresholds and not undercut. Match the form to how much floor clearance the leaf has and how much foot traffic crosses the stop.
