Ives IVE-FS444-US26D – Frequently Asked Questions

1) Will an Ives FS444 floor stop reach a door that has a large undercut over the finished floor?
The FS444 is built for exactly that problem. It handles door undercuts up to 2-1/2 inches, and the stop itself stands 3 inches high, so it still catches the door face on openings that have been cut high for carpet, transitions, or air return. On a door hung close to the floor a stop this tall is more than you need, and a low-profile floor bumper is the better pick.
2) Does the Ives FS444 hold a door open, or does it only stop it?
Stop only. The FS444 catches the door at the end of its swing and keeps it off the wall, but there is no catch or magnet to keep it standing open. If the job needs hold-open, the Orca Hardware 22HD Series gooseneck floor unit is listed as a door holder, and the SOSS MDH is a magnetic door holder and stop measuring 3-5/16 by 1-3/4 inches. Ordering a stop when the door has to stay open is the most common mistake on this kind of part.
3) What fasteners come with the Ives FS444, and can I mount it on a wood floor?
The FS444 ships with fasteners sized for heavy-duty masonry, so a concrete slab, terrazzo, or tile-over-concrete install is covered out of the box. Mounting into a wood subfloor or a wood-framed floor means supplying your own screws and anchor for that substrate. Worth checking before the crew is on site, because the included hardware is the masonry set.
4) Should I use a tall floor stop like the Ives FS444 or a low dome floor bumper?
It comes down to the gap under the door. The FS444 is a tall commercial stop that works with undercuts up to 2-1/2 inches, which is what you want on doors cut high for carpet or airflow. A low bumper only works when the door bottom sits close to the floor: the Deltana UFBS138 is a 1-3/8 inch square solid brass bumper, the Emtek 2254 measures 1-3/8 by 1-1/4 inches, and the Orca Hardware 23LP is a low-rise dome. Those sit nearly flush and are far less of an obstacle underfoot, so they suit corridors and rooms where a 3 inch stop in the walk path is a nuisance.
5) What other floor stops reach a door that has a deep undercut?
The Ives FS444 stands 3 inches high and accommodates door undercuts up to 2-1/2 inches, which is what lets the tip meet the door face on an opening with a tall gap under the leaf. The closest equivalents in form are the gooseneck-style stops, where the tip sits at the top of a riser rather than down at floor level: the Delaney Gooseneck Floor Door Stop, the Emtek 2253 Goose Style Door Stop, and the Orca Hardware 22HD Series goose neck floor stop with black tip. All three are floor-mounted and use the same raised-arm geometry as the FS444.
6) The door sits almost flat to the floor with no real undercut. What floor stop suits that better than a tall one?
A low-profile dome or half-dome stop meets the door face close to the floor, which fits an opening with little or no gap under the leaf. The Orca Hardware 23LP Series is a low rise dome floor stop with a gray tip and is listed with a door stop function; the Delaney Dome Door Stop and the Emtek 2251 Half Dome Door Stop are the same dome form. The Ives FS444 is built the other way, standing 3 inches high to cover undercuts up to 2-1/2 inches, so it suits an opening where the door bottom clears the floor by a wide margin.
7) I need the door held open, not just stopped. Which product does that?
The Ives FS444 is a floor stop: it stops the door before it strikes a wall or adjacent surface and prevents door, wall and frame damage, but it does not latch the door in the open position. For holding, the SOSS MDH Magnetic Door Holder and Stop measures 3-5/16 inches by 1-3/4 inches and is rated heavy duty, combining both jobs in one floor-mounted unit. The Orca Hardware 22HD Series goose neck is also listed with a door holder function.
8) Can a small round floor bumper do the same job as a tall floor stop?
They solve different openings. Floor bumpers such as the Deltana UFB4505 round universal floor door bumper at 1-1/2 inches, the Deltana UFBS138 square universal floor door bumper at 1-3/8 inches, the Emtek 2254 floor door bumper at 1-3/8 by 1-1/4 inches, and the Emtek 2257 cylindrical floor bumper at 1-1/2 inches all meet the door low, near the bottom edge. The Ives FS444 stands 3 inches high and is built to accommodate door undercuts up to 2-1/2 inches, so on a door with a tall undercut the FS444 tip reaches the door face where a short bumper would pass under it.
9) Is the Ives FS444 floor stop certified to ANSI/BHMA for a spec'd commercial job?
Yes. The FS444 carries ANSI/BHMA 156.16, L12131, and it is classified as a heavy duty commercial product with a brass substrate. That is the citation to put on the submittal when the drawing calls for a certified floor stop.
10) Can the Ives FS444 be used on an exterior door or a covered entry?
Brass substrate, and it is made for interior and exterior use, so an entry vestibule, a loading dock door, or a covered exterior opening is within its intended range. Brass is the reason: it holds up to moisture better than a plated steel stop in the same spot.
11) What finish does the Ives FS444 come in, and will it match the rest of my door hardware?
Nine finishes are offered, so matching an existing building standard is usually straightforward: 605 bright brass, 606 satin brass, 612 satin bronze, 613 satin bronze oil-rubbed, 619 satin nickel, 622 matte black, 625 bright chrome, 626 satin chrome, and 643E aged bronze. Order by the suffix, for example FS444-US26D for 626 satin chrome or FS444-BLK for 622 matte black. If the levers and closers in the building are 626, that is the finish that will disappear into the opening.
12) Will the Ives FS444 scuff or dent the door when it hits, and can the tip be replaced later?
The contact point is a black non-marring rubber tip, so the door face takes the hit against rubber rather than metal. The tip is replaceable, which matters on a fleet of high-traffic openings: when it flattens out after a few years you swap the tip instead of pulling the anchored base out of the slab and redoing the floor.
13) Is door thickness a factor when choosing between these floor stops?
It can be, depending on the model. The Orca Hardware 22HD Series goose neck floor stop lists a door thickness range of 1-3/8 inch or 1-3/4 inch. The Ives FS444 is specified by the gap under the door instead, accommodating undercuts up to 2-1/2 inches, and it stands 3 inches high. On a job with doors outside a listed thickness range, that difference decides which one goes on the drawing.
14) Our facility spec calls for a certified commercial door stop. Which of these carries a standard?
The Ives FS444 is certified to ANSI/BHMA 156.16, L12131, is designated commercial, and carries a heavy duty rating with a brass substrate, which is the combination a facility standard usually asks for. Among the alternatives, the SOSS MDH Magnetic Door Holder and Stop is also listed at a heavy duty level, though it is a magnetic holder-and-stop unit measuring 3-5/16 inches by 1-3/4 inches rather than a raised floor stop.
15) Is the Ives FS444 heavy enough for a school corridor or hospital door that gets slammed all day?
That is the application it is built for. Heavy duty rating, brass substrate rather than a die-cast body, ANSI/BHMA 156.16 L12131 certification, and masonry fasteners for a solid anchor into a slab. It is classified as a commercial product, which is the difference between this and a residential bumper that will loosen under that traffic.
16) I want a decorative floor stop for a residential or hospitality interior, not a commercial one. What are the alternatives to the Ives FS444?
The FS444 is a commercial-classified heavy duty stop, so it looks utilitarian next to residential trim. For a decorative solid brass bumper, Deltana offers the UFBD3505 round decorative bumper at 3-1/2 inches, the UFBP4505 pattern cap bumper at 1-5/8 inches, and the UFB4505 round bumper at 1-1/2 inches. Emtek makes the 2251 half dome stop and the 2257 cylindrical floor bumper at 1-1/2 inches. Those are the ones to look at when appearance drives the choice on a guest room or a residential unit.
17) Is the Ives FS444 handed, and does the door thickness matter when I order it?
Neither one is a factor. A floor stop mounts to the floor in the door's swing path and contacts the door face, so there is no left or right hand version and no door thickness to specify. The only choices on the order are the finish and the mounting location. What does need checking is the gap under the door, since the stop is sized for undercuts up to 2-1/2 inches.
18) What is a more decorative floor stop for a lobby or a finish-sensitive corridor?
The Deltana UFBD3505 is a 3-1/2 inch round universal floor bumper in a decorative solid brass design, and the Deltana UFBP4505 is a 1-5/8 inch round universal floor door bumper with a pattern cap, also solid brass. Both sit low and read as a finished floor detail. The Ives FS444 uses a brass substrate as well and comes in nine finishes including 605 bright brass, 613 satin bronze oil-rubbed and 622 matte black, but its 3 inch height and replaceable black non-marring rubber tip put it in the functional heavy-duty class rather than the low decorative one.
19) We are matching existing stops that have black tips. Which ones use a black tip?
The Ives FS444 uses a replaceable black non-marring rubber tip, and the Orca Hardware 22HD Series goose neck floor stop also carries a black tip, so the two read the same way from across a corridor. The Orca 23LP Series low rise dome floor stop uses a gray tip instead, which is worth knowing before ordering into a run of doors already fitted with black.
