Rockwood 443 US26D – Frequently Asked Questions
1) Will a Rockwood 443 dome stop clear a threshold or an undercut door?
That is exactly what the 443 is built for. It's the high dome version, made for doors with thresholds or doors cut high off the floor, so the bumper meets the door face instead of sitting below it. If your door hangs close to a flat finished floor, a low-rise dome like the Orca 23LP series is the better match.
2) Does the Rockwood 443 come with fasteners, or do I have to buy screws separately?
Screws are in the box. Each 443 is packed with both wood screws and machine screws, so you can anchor into a wood subfloor or into a tapped hole in concrete or metal without sourcing hardware separately.
3) Can I use this dome stop outdoors or in a wet entry?
For exterior openings, order it with the EXP suffix. That swaps in an exterior screw pack that is stainless steel plated to match the finish, which is what you want at an entry that sees weather or wash-down. The stop body itself is solid cast brass with a rubber bumper.
4) Does the Rockwood 443 meet an ANSI/BHMA standard for a spec job?
It is listed to ANSI A156.16 with type number L02161, which is the BHMA standard covering auxiliary door hardware such as floor stops. That designation is what a specifier or institutional buyer needs to see on the submittal.
5) We need the door to stay open, not just stop - is the Rockwood 443 the right part?
No. The Rockwood 443 is a dome floor stop only; it arrests the door swing and does not hold it. For a hold-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 Hardware 22HD Series goose neck unit, which is catalogued with a door holder function for 1-3/8 inch or 1-3/4 inch doors.
6) What is the closest commercial equivalent to the Rockwood 443 high dome stop from another manufacturer?
The Ives FS13 and FS17 are the nearest commercial counterparts. The Rockwood 443 is a solid cast brass dome floor stop with a rubber bumper, packed with both wood screw and machine screw fasteners. The Ives FS13 is a heavy-duty brass floor dome stop with a replaceable rubber bumper, and the Ives FS17 is a heavy-duty brass floor dome stop with a rubber bumper. If the ability to swap a worn bumper matters on a high-traffic opening, the FS13 calls out a replaceable bumper by name.
7) What are the actual dimensions of the Rockwood 443 floor stop?
Listed dimensions are 1/2 x 1-7/8 x 1-15/16 inches. Use those numbers to check clearance under the door leaf and to confirm you have room on the floor for the base without catching a threshold edge or carpet transition.
8) Which finishes does the Rockwood 443 high dome stop come in?
Two finishes are offered: 613 satin bronze oil-rubbed and 626 satin chrome. The 626 matches most commercial lever and closer hardware specified in satin chrome, while 613 is the darker oil-rubbed bronze used on bronze entrance packages.
9) What is a good alternative to the Rockwood 443 if I want a residential-looking floor bumper?
For residential or decorative openings, Deltana's solid brass universal floor bumpers cover several looks: the UFB4505 round at 1-1/2 inches, the UFBP4505 with a pattern cap at 1-5/8 inches, the UFBS138 square at 1-3/8 inches, and the UFBD3505 decorative round at 3-1/2 inches. Emtek's 2251 half dome and 2254 floor door bumper are other options. None of those are carried with the Rockwood's A156.16 listing, so for a spec'd commercial opening stay with the 443.
10) I need to stop a door in the middle of a corridor where a floor stop is a trip hazard. Is this the right part?
No. A dome stop like the 443 mounts to the floor in the path of the door swing, so anywhere foot traffic crosses that arc it becomes an obstruction. In those openings use an overhead stop or a wall stop instead, and save the floor dome for openings where the stop sits tight against a wall or in a recess.
11) For a residential or light commercial door, is there a simpler floor stop than the Rockwood 443?
Yes. The Rockwood 443 is a commercial-grade cast brass dome stop built to ANSI A156.16, L02161. For lighter residential work, the Sure-Loc DS-FL2 is a cylindrical floor stop for residential doors, the Delaney Dome Door Stop is a dome-style floor stop, and the Emtek 2251 is a half dome door stop. These carry the same basic bumper-at-the-floor idea in a lighter residential format.
12) Our floor stops keep getting kicked loose in a detention corridor - is there a more tamper-resistant option than the Rockwood 443?
The Ives FS18S/FS18L is a security floor stop rated heavy duty, which is the direction to go where abuse or tampering is the failure mode. The Rockwood 443 is a solid cast brass dome stop supplied with both wood screw and machine screw fasteners, so it can be anchored into concrete or wood, but it is a standard dome profile rather than a security-specific design.
13) What is the difference between the Rockwood 443 dome stop and a gooseneck floor stop?
The Rockwood 443 is a low dome that mounts flat to the floor and takes the door on its rubber bumper, sized for doors with thresholds or undercut doors. A gooseneck stop such as the Delaney Gooseneck Floor Door Stop, the Emtek 2253 goose style door stop, or the Orca Hardware 22HD Series goose neck unit rises on a curved post so the contact point meets the door higher off the floor. Choose the gooseneck when floor-to-door clearance is too great for a dome to reach the door face.
14) Is a universal floor bumper the same thing as the Rockwood 443 dome stop?
They serve the same opening but are not interchangeable in appearance or footprint. The Rockwood 443 is a cast brass high dome stop measuring 1/2 inch by 1-7/8 inch by 1-15/16 inch. The Deltana universal floor bumpers are a different family: the UFB4505 is a round solid brass bumper at 1-1/2 inch, the UFBP4505 is a 1-5/8 inch round bumper with a pattern cap, and the UFBD3505 is a decorative round bumper at 3-1/2 inch. If you are matching existing Rockwood dome stops down a corridor, stay with the 443 profile.
