Ives FS44626D – Frequently Asked Questions

1) Will a floor stop still catch the door if there's a big gap under it for carpet?
That gap is what the Ives FS446 is built for. It accommodates door undercuts up to 2-1/2 inches, so it still contacts the leaf over a thick carpet and pad, over tile that was laid after the door was hung, or where the door was cut for air transfer. Smaller floor bumpers, like the Deltana UFBS138 square bumper at 1-3/8 inches or the Emtek 2254 at 1-3/8 x 1-1/4 inches, are much lower pieces of hardware meant for doors that sit close to the finished floor. Measure from the bottom of the door to the floor at the point where the stop will land, and if that number is under 2-1/2 inches the FS446 works.
2) Does the Ives FS446 hold a door open, or is it only a stop?
Both. The FS446 stops the door on the rubber tip like any floor stop, and it holds the door open when you engage the hook into the strike on the door. The hold-open is manual in both directions: someone has to flip the hook up to catch it, and someone has to disengage it by hand to let the door close. Nothing releases it automatically and nothing holds it magnetically. For a corridor or entry door that people prop all day, that positive catch is the point. If you want the door to close normally every time and only need something to protect the wall, order a stop-only bumper instead.
3) What fasteners come with the Ives FS446 floor stop and what am I mounting it into?
The FS446 ships with fasteners for heavy-duty masonry applications, so anchoring into a concrete slab is covered out of the box. It is a masonry-mount device by design. If you are fastening into a wood subfloor, over a raised floor, or through a topping you will be sourcing your own anchors to suit that substrate. Drill the floor from the manufacturer's template with a masonry bit, set the anchors, then check the hook lines up with the strike on the door before you call it done. Get the position right the first time: every relocation leaves a hole in a finished floor.
4) What floor stop from another brand is the closest match to the Ives FS446 with its manual hold-open?
The Ives FS446 is a floor-mounted unit that stops the door and also holds it open: the hook is engaged by hand into the strike and has to be disengaged by hand to release. The nearest cross-brand match is the Orca Hardware 22HD Series goose neck floor stop with black tip, which is specified as a door holder rather than a stop only. The Orca unit lists a door thickness range of 1-3/8 inch or 1-3/4 inch, so measure the door leaf before substituting; the FS446 is a heavy duty commercial unit supplied with fasteners for heavy duty masonry applications, so also confirm the floor substrate you are anchoring into.
5) I only need the door stopped, not held open. What is the simpler alternative to an Ives FS446?
The FS446 carries both functions, and the hold-open hook stays engaged until someone releases it by hand, which is more mechanism than a plain doorstop opening needs. For stop-only duty, the Orca Hardware 23LP Series dome floor stop is a low rise unit with a gray tip specified as a door stop, and the Emtek 2251 Half Dome Door Stop and Delaney Dome Door Stop are dome-profile floor stops as well. Any of the three ends the door swing without a hook or a door-mounted strike to install, so there is no strike alignment step at the door bottom.
6) The bottom of my door clears the floor by more than 2-1/2 inches. What floor stop reaches that high?
The Ives FS446 is built to accommodate door undercuts up to 2-1/2 inches, so an opening with more clearance than that needs a taller unit. The Deltana UFBD3505 is a round universal floor bumper at 3-1/2 inches in solid brass with a decorative cap, which is the tallest floor unit among the comparable bumpers. It is a bumper, so it stops the door but does not hold it open; if the opening needs both functions at that clearance, a wall-mounted or overhead holder is the direction to look rather than a floor unit.
7) Is there a hold-open that does not require bending down to unhook it like the Ives FS446?
The FS446 holds the door open by a hook that is engaged into the strike by hand and has to be disengaged by hand to release, which means a trip to the floor at each end of the cycle. The SOSS MDH is a magnetic door holder and stop measuring 3-5/16 inches by 1-3/4 inches and rated heavy duty, holding the door magnetically instead of through a mechanical hook. Both units combine the holder and the stop in one device, so either one covers the opening with a single floor-level installation.
8) Does the Ives FS446 meet ANSI/BHMA for a commercial spec?
It does. The FS446 is certified to ANSI/BHMA 156.16, listed as L11371 for the brass version and L31371 for the aluminum version, and it is a commercial, heavy-duty rated stop. Those are the two codes to cite on a submittal, and which one you put on the sheet depends on the substrate you order. That certification plus the heavy-duty classification is what usually separates it from residential floor bumpers when a spec calls out a certified stop and holder.
9) Is the Ives FS446 brass or aluminum, and does it matter which one I order?
The FS446 is made in both, brass or aluminum substrate, and the finish you pick is what determines which one you get. 628 Clear Anodized Aluminum is the aluminum-bodied version; the plated and bronze finishes are the brass-bodied ones. It matters on two fronts: the certification code changes with the substrate, L11371 for brass and L31371 for aluminum, so a submittal has to name the right one, and brass is the heavier material if you want mass behind the door in a high-traffic opening.
10) What finishes does the Ives FS446 come in and how do I order the one I need?
Ten finishes, ordered by finish code on the part number: 605 Bright Brass (FS4463), 606 Satin Brass (FS446-US4), 612 Satin Bronze (FS446-US10), 613 Satin Bronze Oil-Rubbed (FS44610B), 619 Satin Nickel (FS44615), 622 Matte Black (FS446-BLK), 625 Bright Chrome (FS446-US26), 626 Satin Chrome (FS44626D), 628 Clear Anodized Aluminum (FS44628) and 643E Aged Bronze (FS446-643E/716). If you are matching hinges, levers and kick plates already in the building, work from the BHMA number rather than the finish name, since 626 satin chrome and 619 satin nickel read similarly in a photo and do not match on the door.
11) I only need something to keep the door off the wall, not a hold-open. What's the simpler option?
Skip the FS446 and buy a plain floor bumper. The hook and strike on the FS446 are there for hold-open, and if nobody is going to use them you are paying for hardware and drilling a strike into the door for nothing. Straight stop-only options include the Orca Hardware 23LP low-rise dome floor stop with a gray tip, the Deltana UFBS138 square universal floor bumper at 1-3/8 inches, the Deltana UFB4505 round universal bumper at 1-1/2 inches, and the Emtek 2257 cylindrical floor bumper at 1-1/2 inches. Those suit doors sitting close to the floor. If the door has a deep undercut, come back to the FS446, which handles up to 2-1/2 inches.
12) Is there a floor door holder that doesn't make you bend down and flip a hook?
The SOSS MDH is the magnetic alternative, a heavy-duty magnetic door holder and stop measuring 3-5/16 x 1-3/4 inches. It catches the door magnetically instead of with a hook, so releasing it is a matter of pulling the door. The FS446 hook has to be engaged by hand and disengaged by hand, which is deliberate: it will not let go on its own when someone leans on the door, and that matters on an exterior or vestibule door in wind. Pick the magnet for convenience, pick the hook when you want the door to stay put until a person decides otherwise.
13) Can a floor bumper like the Deltana UFB4505 or Emtek 2257 replace an Ives FS446?
Only if the hold-open is not part of the job. The Deltana UFB4505 is a 1-1/2 inch round universal floor door bumper in solid brass and the Emtek 2257 is a 1-1/2 inch cylindrical floor bumper; both arrest the door swing at the floor. The FS446 does that too, but it adds a hook that engages a strike to hold the door open until it is released by hand, and it is built to reach a door undercut of up to 2-1/2 inches, roughly an inch more clearance than those two bumpers stand. On a corridor or vestibule door that has to stay propped, a bumper is not a substitute.
14) My door sits close to the floor with almost no undercut. Which floor stops fit that little clearance?
The Ives FS446 is sized to reach a door undercut of up to 2-1/2 inches, which is more reach than a tight-swinging door needs. For a door bottom that clears by roughly an inch, the Orca Hardware 23LP Series dome floor stop is a low rise unit with a gray tip specified as a door stop, the Emtek 2254 floor door bumper measures 1-3/8 inches by 1-1/4 inches, and the Deltana UFBS138 is a square universal floor door bumper at 1-3/8 inches in solid brass. Measure from finished floor to the bottom of the door at the strike point and pick the unit that meets the door face rather than the edge.
15) Can the Ives FS446 go on an exterior door?
Yes, the FS446 is made for interior and exterior use, and it is a commercial, heavy-duty unit. For an outside opening the finish is the decision that lasts: 628 Clear Anodized Aluminum is the aluminum-substrate option, and 622 Matte Black and 643E Aged Bronze are the darker choices for entries where you do not want a bright plated stop weathering in sunlight. It anchors with the supplied heavy-duty masonry fasteners, which suits the concrete stoop or slab you usually find on the outside of an entry door.
16) Will the floor stop scuff the bottom of the door, and can the rubber tip be replaced when it wears?
The FS446 uses a black non-marring rubber tip, so it takes the hit without marking the door face, and the tip is replaceable. That is the part that matters for a maintenance department: when the rubber flattens after a few years of traffic you swap the tip rather than pulling anchors out of the slab and re-drilling the floor. Worth knowing if you are matching stops already installed in a building, the tip color varies by product, for example the Orca 23LP dome stop comes with a gray tip.
17) What's a good floor stop for a finished space where a plain rubber bumper looks wrong?
The FS446 is a working commercial stop and holder, chosen for function over appearance, though it does come in brass finishes like 605 Bright Brass and 606 Satin Brass if the space calls for it. Where the look drives the decision and you do not need a hold-open, the Deltana UFBD3505 is a 3-1/2 inch decorative solid brass floor bumper, the Deltana UFBP4505 is a 1-5/8 inch solid brass bumper with a pattern cap, and the Emtek 2251 is a half dome stop. Those are stops only, so on a door people prop open regularly you still want the hooked holder.
18) What other goose-profile floor stops are there if I am matching a decorative trim package rather than a commercial one?
The Ives FS446 is a commercial heavy duty unit built on a brass or aluminum substrate and offered in finishes from 605 bright brass to 622 matte black and 628 clear anodized aluminum, so it will often finish-match a trim package on its own. Where the rest of the package comes from a single decorative line, the Delaney Gooseneck Floor Door Stop and the Emtek 2253 Goose Style Door Stop carry the same goose profile within those brands. The difference to weigh is function: the FS446 pairs its stop with a hook-and-strike hold-open, so verify the goose-profile unit you pick does what the opening asks of it.
19) If the look of the unit on the floor is what matters, what shapes and sizes are available besides the Ives FS446 hook style?
The FS446 is a hook-style floor unit in brass or aluminum, anchored with masonry fasteners and finished in options such as 613 satin bronze oil-rubbed, 619 satin nickel and 626 satin chrome. Among floor bumpers, Deltana offers the UFBS138 square universal floor door bumper at 1-3/8 inches, the UFB4505 round universal bumper at 1-1/2 inches, and the UFBP4505 round bumper with a pattern cap at 1-5/8 inches, all in solid brass, while the Emtek 2251 Half Dome and Delaney Dome Door Stop give a dome profile. Square bases read cleanly under square rosettes and levers; the round and dome shapes sit lower in the sightline of the floor.
