Ives FS43826D – Frequently Asked Questions

1) Will an Ives FS438 floor stop work on a door with a threshold or a big undercut?

That's exactly the opening the FS438 dome stop is built for. It mounts to the floor rather than the wall, so it works where a threshold, an undercut door, or a floor-level obstruction rules out a wall bumper, and it's the answer where an overhead stop isn't practical. The dome sits low at 9/16 x 1-3/4 x 2 inches, so the door contacts the grey rubber bumper on the crown rather than riding over the top of it.

2) Can I mount the Ives FS438 dome stop on a concrete floor, or only on wood?

Both. The FS438 ships packed with fasteners for light-duty masonry and wood, so a concrete or tile-over-slab floor and a wood subfloor are both covered out of the box. On heavier commercial slabs, or over a floor covering where the supplied light-duty anchors won't hold torque, plan on substituting anchors rated for that substrate; nothing about the stop's footprint changes.

3) Does the Ives FS438 meet ANSI/BHMA for a commercial job spec?

Yes, and the certification numbers split by material. The FS438 is built to ANSI/BHMA A156.16, certified L12161 in the brass substrate and L32161 in aluminum. It's a commercial-rated, heavy duty stop, which is what a facility spec or a submittal package for a school, hospital, or government building normally calls for.

4) Is the Ives FS438 brass or aluminum, and how do I tell which one I'm ordering?

The finish decides the substrate. The FS438 is made in brass or aluminum, and 628 Clear Anodized Aluminum is the aluminum version; the rest of the range is on the brass substrate. That matters for the certification too, since brass is certified L12161 and aluminum L32161 under A156.16. If a spec calls out solid brass, stay off 628.

5) Dome floor stop or gooseneck floor stop, which one do I want?

A dome like the Ives FS438 is a low crown the door edge strikes and stops on, nothing more. A gooseneck rises up on a post and catches the door face higher, and the hook style ones also hold the door open, which the dome does not. If you need the door to stay put when it's parked, look at a gooseneck holder such as the Orca 22HD Series or the Emtek 2253 Goose Style, or a magnetic holder like the SOSS MDH. If you only need to stop the swing and keep the floor clear, the dome is the lower-profile choice.

6) What else could I buy instead of the Ives FS438 dome floor stop?

Straight equivalents in the dome shape are the Orca 23LP Series low rise dome floor stop with a gray tip and the Delaney Dome Door Stop. For a decorative solid brass look on a residential-grade or historic opening, Deltana's universal floor bumpers cover several profiles: the UFB4505 round at 1-1/2 inches, the UFBS138 square at 1-3/8 inches, the UFBP4505 pattern cap at 1-5/8 inches, and the larger UFBD3505 decorative round at 3-1/2 inches. Emtek's 2251 Half Dome and the 2254 floor bumper at 1-3/8 x 1-1/4 inches are the trim-suite matches. What separates the FS438 is the heavy duty commercial rating under ANSI/BHMA A156.16.

7) Will the Ives FS438 hold a door open, or does it only stop it?

Stop only. The FS438 dome takes the impact of the swing on its rubber bumper and protects the wall and molding, but there's no catch or hook, so the door swings back freely. Anyone who needs the leaf to stay open, for a corridor on a moving day or a classroom door, wants a holder instead: the Orca 22HD Series gooseneck is listed as a door holder, and the SOSS MDH is a magnetic holder and stop in one.

8) What is a direct alternative to the Ives FS438 dome floor stop if I want the same low dome shape from another brand?

The Ives FS438 is a heavy-duty cast dome floor stop with a grey rubber bumper, measuring 9/16 inch by 1-3/4 inch by 2 inch. Two dome-profile floor stops sit alongside it: the Delaney Dome Door Stop, part 40260X, and the Orca Hardware 23LP Series dome floor stop, low rise with a gray tip. All three keep the same low, rounded floor-mounted form that clears a swinging door without a tall post. The FS438 carries ANSI/BHMA A156.16 with L12161 for brass and L32161 for aluminum, which is the reference to check against when a project specification calls out a certified stop.

9) I need the door to stay open, not just stop. Is the FS438 the wrong part?

Yes. The Ives FS438 is a floor stop with a grey rubber bumper that arrests the door swing; it does not hold the door open. For holding, the SOSS MDH is a magnetic door holder and stop measuring 3-5/16 inch by 1-3/4 inch, rated heavy duty, which catches and retains the door. The Orca Hardware 22HD Series goose neck lists its function as a door holder. Both take up considerably more floor footprint than the FS438 at 9/16 inch by 1-3/4 inch by 2 inch, which matters on a walking path.

10) What finishes does the Ives FS438 dome stop come in so I can match the rest of my door hardware?

Eleven finishes, covering the standard BHMA range: 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. For a property manager standardizing a building, 626 and 630-family brushed looks are the usual match to commercial lever trim, and 613 or 643E pairs with darker residential-style suites.

11) How far out from the door should I set an Ives FS438, and how much floor does it take up?

The dome footprint is 9/16 x 1-3/4 x 2 inches, so it's a small target on the floor and you position it where the door's swing brings the leaf onto the rubber crown before the handle or the leading edge reaches the wall. Mark from the template that comes with it rather than eyeballing the arc. Low profile helps in corridors and classrooms where a taller gooseneck would be a trip point.

12) Can I use the same Ives FS438 across a whole building, or do I need different stops per door type?

One model covers the fleet as long as the openings take a floor stop. The FS438 doesn't care about door thickness, handing, or whether the leaf is wood, hollow metal, or aluminum, since it mounts to the floor and the door simply contacts the rubber crown. Standardizing means one part number, one drill template, and one spare in the shop across offices, corridors, classrooms, and unit doors. Pick the finish per area and order the rest identically. Openings where the door swings against a wall with no useful floor mount, or where a floor obstruction can't be tolerated, are the ones that need a wall bumper or overhead stop instead.

13) I'm replacing an old dome floor stop that's already anchored in the concrete. Will the Ives FS438 cover the existing holes?

Plan on drilling fresh. The FS438 comes with its own template and its own light-duty masonry and wood fasteners, and the dome base is a compact 9/16 x 1-3/4 x 2 inches, so there's little margin to bridge an off-centre legacy hole. If the old anchor pulled out of the slab, set the new one clear of the damaged hole along the same swing arc and patch the original.

14) What is the difference between the Ives FS438 and a universal floor bumper like the Deltana UFB4505?

The Ives FS438 is a heavy-duty cast dome stop built for commercial openings, carrying ANSI/BHMA A156.16 with L12161 for brass and L32161 for aluminum, in brass or aluminum substrate. The Deltana UFB4505 is a round universal floor door bumper, 1-1/2 inch, in solid brass, from the UFB Series. The Deltana bumper family also includes the UFBS138 square universal floor bumper at 1-3/8 inch and the UFBP4505 round bumper with a pattern cap at 1-5/8 inch, all solid brass. Those are decorative-family bumpers sized by cap diameter; the FS438 is specified by its A156.16 certification, which is what an institutional or government specification will ask for.

15) Is the Emtek 2251 Half Dome the same thing as the Ives FS438?

They share the dome silhouette but they are not the same part. The Emtek 2251 is a Half Dome Door Stop from Emtek's door accessories range. The Ives FS438 is a heavy-duty cast dome floor stop, commercial rated, in brass or aluminum substrate, meeting ANSI/BHMA A156.16 with L12161 for brass and L32161 for aluminum, and it ships with fasteners for light-duty masonry and wood floors. If the opening is on a drawing that calls for an A156.16 stop, the FS438 is the one that answers it; if the requirement is a dome look on a residential-style opening, the Emtek 2251 and the Delaney 40260X Dome Stop cover that shape too.

16) For a high-traffic corridor in a school or hospital, which floor stop holds up alongside the Ives FS438?

The Ives FS438 is rated heavy duty and specified for commercial use, with heavy-duty cast construction and A156.16 certification, L12161 for brass and L32161 for aluminum. Of the floor-mounted alternatives, the SOSS MDH magnetic door holder and stop is likewise rated heavy duty, though it holds the door open rather than only stopping it. The FS438 at 9/16 inch by 1-3/4 inch by 2 inch keeps a low profile in a corridor where a taller gooseneck such as the Orca 22HD Series or the Emtek 2253 Goose Style would sit up in the traffic path.

17) I am standardizing floor stops across a portfolio in solid brass. How does the FS438 line up with the Deltana bumpers?

The Ives FS438 comes in a brass or aluminum substrate, with finish 628 clear anodized aluminum on the aluminum version and the brass substrate carrying finishes such as 605 bright brass, 606 satin brass, 609 blackened brass, 612 satin bronze, and 613 satin bronze oil-rubbed. The Deltana universal floor bumpers are solid brass throughout: the UFB4505 at 1-1/2 inch round, the UFBP4505 at 1-5/8 inch with a pattern cap, the UFBS138 at 1-3/8 inch square, and the UFBD3505 at 3-1/2 inch decorative. Deciding between them comes down to whether the portfolio needs the A156.16 certified commercial stop or a decorative brass bumper profile.

18) Will the grey rubber bumper on the Ives FS438 mark up my finished door or floor?

No. The bumper is non-marring rubber, chosen so it protects the wall, molding, and door finish rather than scuffing it at the contact point. On painted hollow metal and on stained wood doors alike, the grey tip takes the wear instead of the leaf. Worth noting the tip is grey on every finish, so on a bright brass or matte black stop the bumper won't colour-match the metal.

19) Can I substitute a square floor bumper for the Ives FS438 dome stop?

The Deltana UFBS138 is a square universal floor door bumper at 1-3/8 inch in solid brass, and it is the square-profile counterpart to the round bumpers in the same family. The Ives FS438 is a cast dome, 9/16 inch by 1-3/4 inch by 2 inch, with a grey rubber bumper and A156.16 certification, L12161 for brass and L32161 for aluminum. Where the substitution matters is the certification and the mounting footprint: the FS438 ships with fasteners for light-duty masonry and wood floors and is drilled to its own hole pattern, so a swap means new floor holes rather than a drop-in over existing ones.
