Rockwood 441CU US26D – Frequently Asked Questions
1) What comes in the Rockwood 441CU combination unit?
The 441CU is a two-piece set: one No. 441 floor dome stop and one No. 444. That pairing is what makes it work at openings with a threshold and at openings without one, and it converts for undercut or non-undercut doors. So you order one part number and cover either condition rather than guessing at the door bottom clearance before you get to site.
2) Do screws come with the Rockwood 441CU floor stop, and will they work in concrete?
Fasteners ship with the unit: a #12 x 1-1/2 inch flat head wood screw with plastic anchor for wood substrate, and a #12-24 x 1-1/2 inch flat head machine screw with anchor for masonry or concrete. Both mounting conditions are covered out of the box, so you are not making a second trip for anchors.
3) Does the Rockwood 441CU meet ANSI/BHMA for a specified door stop?
It carries ANSI A156.16 with type numbers L02141 and L02161. If your hardware schedule calls out an A156.16 floor stop by L-number, those are the two designations this unit answers to, which is what an institutional or government spec writer is checking before it gets approved.
4) What is the equivalent to a Rockwood 441 floor dome stop from another brand?
The closest cross-brand match is Ives: the FS13 is a heavy duty brass floor dome stop with a replaceable rubber bumper, and the FS17 is a heavy duty brass floor dome stop with a rubber bumper. Both are the same brass dome format. The FS13's bumper is replaceable, which matters if you are maintaining a fleet of openings and want to swap tips rather than pull and re-anchor the base. Orca Hardware's 23LP Series is a low rise dome floor stop with a gray tip if you want the low profile in another line.
5) What is the closest heavy-duty brass floor dome stop to the Rockwood 441CU?
The Ives FS13 is the nearest match in kind: a heavy-duty brass floor dome stop with a replaceable rubber bumper. The Rockwood 441CU is solid cast brass with a rubber bumper and ships as a set of one No. 441 and one No. 444, so it covers both the stop and the companion piece for doors with or without a threshold. The Ives FS17 is the same heavy-duty brass floor dome stop family with a rubber bumper rather than a replaceable one. If the spec calls for ANSI A156.16 L02141/L02161, the 441CU carries it.
6) The door needs to be held open, not just stopped. What should be used instead of a Rockwood 441CU?
The 441CU is a dome stop combination unit - it stops the door and protects the wall, but it does not hold the door open. For hold-open, the Ives FS40 / FS41 / FS42 / FS43 is an automatic floor stop and holder with adjustable door-to-floor clearance, the SOSS MDH is a magnetic door holder and stop measuring 3-5/16 inch by 1-3/4 inch, and the Orca Hardware 22HD Series goose neck floor stop with black tip is listed with a door holder function for 1-3/8 inch or 1-3/4 inch doors.
7) Is a universal floor bumper the same thing as the Rockwood 441CU?
No - they look alike on a cut sheet but do different work. The Deltana UFB4505 is a 1-1/2 inch round universal floor door bumper in solid brass, the UFBS138 is the 1-3/8 inch square version, the UFBP4505 is a 1-5/8 inch round with a pattern cap, and the Emtek 2254 is a 1-3/8 inch by 1-1/4 inch floor door bumper. Those are bumpers taking the door face. The Rockwood 441CU is a combination unit of one No. 441 and one No. 444, convertible for undercut or not undercut doors and intended for doors with or without a threshold, and it carries ANSI A156.16 L02141/L02161 for commercial work.
8) What is the Rockwood 441CU made of and will the bumper hold up in a high traffic corridor?
Solid cast brass body with a rubber bumper, listed as commercial hardware. Cast brass is the reason this specifies into schools, hospitals and hotel corridors rather than a stamped or die-cast residential stop: the base takes repeated door strikes and the rubber takes the impact.
9) Is there an exterior or corrosion resistant screw option for the 441CU?
Yes, order the exterior pack. Add the EXP suffix to the model, written 441CU x EXP, and you get stainless steel plated screws matched to the finish. For an exterior door, a covered entry, or a pool or coastal opening, that is the version to specify.
10) What decorative floor stop can replace a Rockwood 441CU on a finish-sensitive opening?
The Deltana UFBD3505 is a 3-1/2 inch round universal floor bumper in solid brass with a decorative profile, and the Emtek 2257 is a 1-1/2 inch cylindrical floor bumper from the Door Accessories Collection. The Rockwood 441CU itself is solid cast brass and comes in Black Suede Powder, 613 Oil Rubbed Bronze, 626 Satin Chrome, and 606 Satin Brass, with stainless steel plated exterior screw packs available using the EXP suffix ordered as 441CU x EXP.
11) Can I use the Rockwood 441CU on a residential door?
It will mount on one, but the 441CU is catalogued as commercial hardware and a 1-7/8 inch diameter cast brass dome is heavier than most homes need. For a house, the Deltana UFB4505 round universal floor bumper at 1-1/2 inch, the Deltana UFBD3505 decorative round bumper at 3-1/2 inch, or the Emtek 2254 floor bumper at 1-3/8 by 1-1/4 inch are solid brass options sized for residential trim.
