Ives IVE-FS448-US26D – Frequently Asked Questions

1) Is the Ives FS448 certified to an ANSI/BHMA standard for a spec job?
Yes. The FS448 is built to ANSI/BHMA 156.16, and it carries two different type numbers depending on how it is made: L12121 for the brass version and L32121 for the aluminum. When a submittal asks for the BHMA designation, use the one that matches the finish family you ordered. It is a commercial-rated stop, not a residential one.
2) Will the Ives FS448 hold a door open, or does it only stop it?
Stop only. The FS448 arrests the door before it hits the wall; it has no hook or magnet to keep it standing open. If you need the door to stay put, look at a holder instead: the Orca Hardware 22HD Series goose neck 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 plain stop when the job called for a holder is the most common mix-up on this part.
3) What is a lower-profile alternative to the Ives FS448 floor stop?
If the undercut is small and a 3 inch tall stop is more than the opening needs, the low dome and bumper styles sit far closer to the floor. Deltana's UFBS138 square universal floor bumper is 1-3/8 inches, the UFB4505 round is 1-1/2 inches, and the UFBD3505 decorative round is 3-1/2 inches. Emtek's 2254 floor bumper is 1-3/8 by 1-1/4 inches and the 2257 cylindrical bumper is 1-1/2 inches. Orca's 23LP Series is a low-rise dome stop. None of those reach a 2-1/2 inch undercut, so match the height to the gap under your door before you switch.
4) What is a direct alternative to the Ives FS448 floor stop for a door with a large undercut?
The FS448 is built for door undercuts up to 2-1/2 inches, with an overall height of 3 inches, so it reaches up to meet a door that sits high off the finished floor. When the gap under the door is that large, a low-profile floor bumper will not make contact. The closest alternatives in a tall floor stop are the Orca Hardware 22HD Series goose neck floor stop with black tip and the Delaney Gooseneck Floor Door Stop, both goose neck designs that rise off the floor the same way. The Emtek 2253 Goose Style Door Stop is a third goose neck option. Note that the Orca 22HD is listed as a door holder rather than a plain stop, so it is doing a different job at the door.
5) Can I use a low dome floor bumper instead of a goose neck floor stop?
Only if the door sits close to the floor. The Ives FS448 is a 3 inch tall stop sized for undercuts up to 2-1/2 inches, which is the case for doors with a big gap for return air or carpet. A dome or button style bumper sits low and needs the door leaf itself to strike it. If your undercut is small, the Delaney Dome Door Stop, the Emtek 2251 Half Dome Door Stop, and the Orca Hardware 23LP Series low rise dome floor stop with gray tip all work in that role. Measure the gap under the door leaf before you choose, because a low rise dome under a high door does nothing.
6) I need the door to stay open, not just stop. Is the Ives FS448 the right part?
No. The FS448 is a floor stop, so it limits how far the door swings and keeps the leaf off the wall, but it does not latch the door in the open position. For hold-open, the SOSS MDH is a magnetic door holder and stop measuring 3-5/16 by 1-3/4 inches and rated heavy duty, which both stops the door and magnetically retains it open. The Orca Hardware 22HD Series goose neck is also listed with a door holder function. Choose a holder where the opening needs the door parked open for traffic or ventilation, and the FS448 where the door should swing back freely.
7) Which floor stop should I specify when the job calls for an ANSI/BHMA certified stop?
The Ives FS448 carries ANSI/BHMA 156.16 certification, listed as L12121 for the brass substrate and L32121 for aluminum, and is designated for commercial use. Among the goose neck and dome alternatives, the Orca Hardware 22HD Series and 23LP Series, the Delaney Gooseneck and Dome stops, and the Emtek 2251, 2253, 2254 and 2257 are catalogued by series and dimension rather than by ANSI/BHMA designation, so if the submittal has to show a BHMA number the FS448 is the one that carries it. That distinction matters most on institutional and government specifications where the hardware schedule cites BHMA finish and product codes directly.
8) Do I need to buy separate anchors to mount an Ives FS448 floor stop?
Fasteners for drywall and wood come in the box, so a wood subfloor or a drywall condition is covered out of the carton. Concrete slab is the case to plan for: that needs an anchor suited to the slab, which is not part of the packed hardware.
9) What finishes does the Ives FS448 floor stop come in?
Eleven finishes, covering most of what a building already has on its other hardware: 605 bright brass, 606 satin brass, 609 blackened brass, 612 satin bronze, 613 satin bronze oil-rubbed, 619 satin nickel, 622 matte black, 625 bright chrome, 626 satin chrome, 628 clear anodized aluminum, and 643E aged bronze. The 628 is the aluminum substrate version; the rest run on brass. For a property manager matching a fleet of openings, order the same finish code that is on the lever and hinges.
10) Can the rubber tip on the Ives FS448 be replaced when it wears out?
The black rubber tip is replaceable, which is the reason this stop holds up in a high-traffic corridor. When the tip flattens or tears, the stop body and its anchors stay in the floor and only the tip changes. The tip is non-marring, so it will not leave a black scuff on the bottom rail of the door.
11) Should I use a floor stop like the Ives FS448 or a wall stop?
A floor-mounted stop is the answer when the door swings into open space, a glass wall, or a partition that will not take an anchor, and it stops the door where a wall bumper has nothing to hit. The trade-off is a permanent obstruction in the walking path and an anchor through the finished floor. Where there is solid backing directly behind the door at bumper height, a wall stop keeps the floor clear. The FS448 is specifically the version for a high undercut, up to 2-1/2 inches.
12) How much floor space does an Ives FS448 take up, and will it be a trip hazard in a corridor?
The base is 2-1/2 inches in diameter and the stop stands 3 inches tall. That is a small footprint but a real vertical obstruction, so keep it tight to the door's swing arc and out of the main path of travel rather than centered in a doorway people walk through. In a healthcare or education corridor where anything standing off the floor is a problem, a wall stop or an overhead is the better call.
13) What floor bumper works when the door needs to stop against a bumper set into a tile or stone floor?
For a low, finished-floor bumper rather than a tall stop like the Ives FS448, the Deltana universal floor bumper range covers several diameters in solid brass: the UFB4505 round bumper at 1-1/2 inches, the UFBP4505 round bumper with pattern cap at 1-5/8 inches, the UFBS138 square bumper at 1-3/8 inches, and the UFBD3505 decorative round bumper at 3-1/2 inches. The Emtek 2254 floor door bumper measures 1-3/8 by 1-1/4 inches and the Emtek 2257 cylindrical floor bumper is 1-1/2 inches. These are all low bumpers that the door face contacts, so they suit an opening where the door swings nearly to the floor, unlike the FS448, which reaches up over a 2-1/2 inch undercut.
14) Is a solid brass floor bumper the same thing as the Ives FS448?
They are not interchangeable. The FS448 is offered in brass or aluminum substrate with a replaceable black non-marring rubber tip, and it ships with fasteners for drywall and wood applications. The Deltana UFB4505, UFBP4505, UFBS138 and UFBD3505 are solid brass universal floor bumpers in 1-1/2, 1-5/8, 1-3/8 and 3-1/2 inch sizes. Those are low bumpers, so swapping one in for an FS448 changes both the mounting geometry and how far the door swings before it makes contact. If you are matching existing hardware across a set of doors, confirm which of the two shapes is already installed before ordering.
15) Does the goose neck stop I am replacing need to match my door thickness?
Door thickness governs where the stop makes contact on the leaf. The Ives FS448 is a commercial floor stop sized around a 3 inch height and 2-1/2 inch undercut. Among the goose neck peers, the Orca Hardware 22HD Series is specified for 1-3/8 inch or 1-3/4 inch doors, which covers standard residential and standard commercial leaves. Measure your leaf thickness and the gap under the door together, since both decide whether a goose neck reaches the door face squarely.
16) Can the Ives FS448 be used on an exterior door?
Yes, the FS448 is rated for interior and exterior use. For an outside opening, the aluminum substrate version in 628 clear anodized is the finish that is meant to live outdoors; the brass finishes will patina in weather, which is fine on 613 oil-rubbed bronze and a problem on 605 bright brass.
17) Is the Ives FS448 brass or aluminum?
Both are made. The substrate follows the finish: 628 clear anodized is the aluminum build, and the remaining finishes run on brass. That distinction matters on a submittal, since the brass version certifies as L12121 and the aluminum as L32121 under ANSI/BHMA 156.16.
18) What do I order to get an Ives FS448 in matte black?
Matte black is finish 622, ordered as FS448-BLK. The other codes follow the old US convention: FS448-US26D for 626 satin chrome, FS448-US10B for 613 oil-rubbed bronze, FS448-US15 for 619 satin nickel, and FS448-US28 for 628 clear anodized aluminum. Finish is the only thing you specify on this stop; there is no handing and no size choice.
19) What is a decorative alternative to a plain commercial floor stop for a lobby or tenant entry?
The Ives FS448 is a commercial floor stop offered across finishes including 605 bright brass, 613 satin bronze oil-rubbed, 619 satin nickel and 622 matte black. Where the look matters more than a BHMA designation, the Deltana UFBD3505 is a decorative round solid brass floor bumper at 3-1/2 inches and the Deltana UFBP4505 is a 1-5/8 inch round bumper with a pattern cap. The Emtek 2251 Half Dome and 2257 cylindrical floor bumper are lower profile decorative shapes. All of these are low bumpers rather than tall stops, so they suit a door that closes near the floor.
