Ives FS18S / FS18L Security Floor Stop

The Ives FS18S and FS18L are grouted-in security floor stops engineered for high-vandalism and high-security environments. Molded from black flame-resistant, resilient rubber around a heavy-duty stud, these stops are set into concrete and grouted flush — leaving zero exposed fasteners once installed. The result is a door stop that cannot be unscrewed, pried, or removed without destroying the floor. Available in two heights: 1-1/2" (FS18S) and 3-1/2" (FS18L).

Key Features

  • Tamper-Proof Grouted Installation: No exposed fasteners after grouting — cannot be removed or tampered with.
  • Two Height Options: 1-1/2" (FS18S) for low-profile applications; 3-1/2" (FS18L) for standard floor or concrete wall use.
  • Flame-Resistant Rubber Construction: Heavy-duty resilient rubber molded around a reinforced stud; non-marring and impact-resistant.
  • ANSI/BHMA 156.16 Compliant: Meets the standard for door hardware accessories.
  • Consistent Footprint: Both models share 2" diameter and 2-1/2" length for uniform hole preparation.

Technical Specifications

  • Model FS18S: H: 1-1/2", Diameter: 2", Length: 2-1/2"
  • Model FS18L: H: 3-1/2", Diameter: 2", Length: 2-1/2"
  • Material: Black flame-resistant resilient rubber over heavy-duty stud
  • Duty Level: Heavy Duty
  • Use: Commercial
  • Standard: ANSI/BHMA 156.16

Installation Overview

  • Core or drill a hole in the concrete floor (or wall for FS18L) to manufacturer-specified depth and diameter.
  • Set the stop in the hole and align with the door swing path.
  • Fill with concrete grout; allow full cure before use.
  • No fasteners are exposed after installation — the stop is permanently secured.

Typical Applications

  • Correctional facilities and jail cells
  • Detention centers and holding areas
  • Mental health and behavioral health facilities
  • Secure government and institutional buildings
  • Vandalism-prone public spaces and educational security zones

Ives IVE-FS18L – Frequently Asked Questions

1) Can an inmate or a vandal pull an Ives FS18 floor stop out of the floor?
Not without destroying the concrete around it. The FS18S and FS18L are set into a hole in the slab and grouted in, so once the grout cures there are no exposed fasteners at all. There is no screw head to back out and no flange to get a pry bar under. That is the entire point of the design, and it is why these show up in jail cells, detention holding areas, and behavioral health rooms, where a conventional screw-down stop eventually becomes a loose piece of steel in someone's hand.
2) FS18S or FS18L: which height Ives security floor stop should I order?
Rubber height is the only difference between them. FS18S stands 1-1/2 inches, FS18L stands 3-1/2 inches, and both share a 2 inch diameter and 2-1/2 inch length. Pick by where the door leaf actually makes contact and by traffic across the stop: the 1-1/2 inch FS18S is the low-profile choice when the stop lands in a walking path, and the 3-1/2 inch FS18L is the standard floor height and the one used when the stop goes into a concrete wall instead of the floor.
3) Will an Ives FS18 security floor stop work on a wood, tile, or vinyl floor?
No. It is a grouted stop, so it only goes where you can core a hole and pack concrete grout around the body. Wood framing, tile over subfloor, raised access flooring, or a topping you cannot drill and grout all rule it out. For those openings you want a conventional floor-mounted bumper instead, such as the Deltana UFB4505 round universal floor door bumper in solid brass at 1-1/2 inches, or the Emtek 2254 floor door bumper at 1-3/8 by 1-1/4 inches. You give up the tamper resistance, but you get a stop that actually fastens to the floor you have.
4) How do you install a grouted security floor stop, and is the hole prep the same for both sizes?
Prep does not change between the two models. Both the FS18S and FS18L are 2 inches in diameter and 2-1/2 inches long, so one hole size and depth covers either one, which matters if you are standardizing a whole facility on a single core bit. Sequence is core or drill the concrete to the manufacturer's specified depth and diameter, set the stop in the hole aligned to the door's swing path, fill with concrete grout, and let it cure fully before the door is put back in service. Get the alignment right the first time; once the grout sets, moving it means breaking out the floor.
5) The floor cannot be cored and grouted - what floor stop matches the Ives FS18S or FS18L height instead?
Match on rubber height so the door still strikes where it should. The FS18S carries a 1-1/2 inch rubber height and the FS18L a 3-1/2 inch height, both on a 2 inch diameter and 2-1/2 inch length. At 1-1/2 inch, the Deltana UFB4505 is a round universal floor door bumper in solid brass and the Emtek 2257 is a 1-1/2 inch cylindrical floor bumper. At 3-1/2 inch, the Deltana UFBD3505 is a round universal floor bumper in solid brass. Understand what changes with the swap: the FS18S and FS18L get their tamper resistance from being set into the concrete and grouted flush, with no fasteners exposed once cured, so moving to a floor bumper is a change in how the stop is secured, not only in material.
6) Can a dome floor stop be used on a cell door or behavioral health opening in place of the Ives FS18S?
Those are different requirements. The Delaney Dome Door Stop, the Emtek 2251 half dome door stop, and the Orca 23LP low rise dome floor stop are dome-profile floor stops for standard commercial openings. The Ives FS18S and FS18L are black flame-resistant resilient rubber molded over a heavy-duty stud, set into a cored hole and grouted so there is nothing exposed to unscrew or pry, and they meet ANSI/BHMA 156.16. When the specification for a cell, holding area, or behavioral health door calls for a stop that cannot be removed without destroying the floor, that grouted-in construction is the reason the FS18S and FS18L are written into it.
7) The Ives FS18S and FS18L only stop the door - what should I use if the opening also needs to be held open?
The FS18S and FS18L are stops, so pick a holder when the door has to stay open on its own. The Orca 22HD Series goose neck floor stop with black tip is listed as a door holder and covers a door thickness range of 1-3/8 or 1-3/4 inch. The SOSS MDH is a magnetic door holder and stop measuring 3-5/16 by 1-3/4 inches and carries the same heavy duty rating the FS18S and FS18L do. On a secure opening, weigh that carefully: a holder is a serviceable device, while the FS18 stops are grouted permanently into the floor.
8) Does the Ives FS18 hold a door open or only stop it?
Stop only. There is no catch, no magnet, and no hold-open feature. It is a rubber bumper on a grouted stud that limits swing and absorbs the strike. If you need the leaf to stay open, that is a different piece of hardware: the Orca Hardware 22HD Series goose neck floor stop with black tip is listed as a door holder for 1-3/8 or 1-3/4 inch doors, and the SOSS MDH magnetic door holder and stop measures 3-5/16 by 1-3/4 inches and is heavy duty rated. Neither is a grouted assembly, so decide first whether hold-open or tamper resistance is the requirement, because on a secure opening you rarely get both.
9) Does the Ives FS18 floor stop meet ANSI/BHMA for an institutional hardware spec?
It is compliant with ANSI/BHMA 156.16, the standard covering door hardware accessories, and it is a heavy duty commercial grade item. For a government, healthcare, or education submittal, that plus the grouted tamper-proof installation and the flame-resistant rubber body is what you are putting on the schedule. Same standard applies to both the 1-1/2 inch FS18S and the 3-1/2 inch FS18L, so specifying both heights across a building does not split your compliance basis.
10) Can a security floor stop be set into a concrete wall instead of the floor?
The FS18L is the model for that. At 3-1/2 inches of rubber height it is called out for standard floor use or for setting into a concrete wall, which is how you stop a door leaf that swings back against a masonry wall with nothing on the floor to catch it. Install is the same grouted method, so the wall has to be solid concrete you can drill and grout, not block infill or drywall over studs. The 1-1/2 inch FS18S is the low-profile floor version.
11) Our floor stops keep getting kicked loose in school corridors and public restrooms. Will a grouted stop fix that?
That is exactly the failure this stop is built against. Vandalism-prone public spaces and educational security zones are named applications, and because the body is grouted into the slab with nothing exposed to unscrew, the repeat maintenance call goes away. The trade-off is permanence. You cannot relocate it later, so if the door, the closer, or the swing is likely to change, set it where the leaf contacts today and accept that a change means new concrete work. Between the two heights, the 1-1/2 inch FS18S is the one to use in a corridor where people walk over the stop.
12) What is a lower-profile floor stop than the 1-1/2 inch Ives FS18S?
The FS18S is the shorter of the two Ives security stops at 1-1/2 inch rubber height. If the door bottom or an undercut needs less than that, the Deltana UFBS138 is a square universal floor door bumper at 1-3/8 inch in solid brass, the Emtek 2254 floor door bumper measures 1-3/8 by 1-1/4 inches, and the Orca 23LP dome floor stop is a low rise profile. The FS18S remains the choice where the stop has to be grouted in without exposed fasteners, since that is what makes it tamper resistant.
13) Is the mounting stud included with the Ives FS18, or is that ordered separately?
The stud is part of the stop. Rubber is molded directly around a heavy-duty reinforced stud as one piece, so there is nothing to assemble and no separate anchor to buy. What the job still needs is the coring and the concrete grout, which are site materials rather than packaged hardware. Order the stop by height, FS18S at 1-1/2 inches or FS18L at 3-1/2 inches, and plan the grout with the rest of the concrete work.
14) Will a security floor stop mark up a finished floor or damage the door face?
The strike surface is black resilient rubber, non-marring and impact resistant, so it takes the hit rather than passing it into the door face or the closer arm. The rubber is also flame resistant, which is part of why it clears in correctional and behavioral health work where surface materials get scrutinized. Bear in mind it is black rubber and nothing else, with no plated or decorative cap, so it reads as security hardware wherever it lands.
15) Is there a finish option on the FS18, or something better looking for a lobby door?
Black rubber is the only appearance, in both the 1-1/2 inch and 3-1/2 inch heights. There is no finish axis to specify, because the stop is meant to disappear into a secure floor rather than match a lobby's hardware finish. Front-of-house openings are better served by a decorative floor bumper: the Deltana UFBD3505 round universal floor bumper is solid brass at 3-1/2 inches, and the Deltana UFBP4505 pattern cap bumper is solid brass at 1-5/8 inches, both of which match the 3-1/2 inch and low-profile heights fairly closely while looking like finish hardware.
16) Black rubber is too utilitarian for a finished lobby - what floor stop looks better than the Ives FS18L?
The FS18S and FS18L are black flame-resistant rubber, chosen for correctional, detention, and vandalism-prone spaces rather than for appearance. For a finished area, the Deltana UFBD3505 is a decorative round universal floor bumper at 3-1/2 inch in solid brass, the Deltana UFBP4505 is a 1-5/8 inch round floor door bumper with a pattern cap in solid brass, and the Emtek 2251 is a half dome door stop. Keep the FS18S and FS18L on the secure openings where the grouted, fastener-free installation is the requirement, and use the brass bumpers in the public spaces.
17) The rest of the building uses brass floor bumpers - can the Ives FS18S go on just the secure doors without the door swing changing?
Yes, and matching the height is what keeps the swing consistent. The FS18S has a 1-1/2 inch rubber height, the same height the Deltana UFB4505 round universal floor door bumper and the Emtek 2257 cylindrical floor bumper carry, so a door stopping against an FS18S lands in the same place as one stopping against those. The FS18L at 3-1/2 inch pairs the same way with the Deltana UFBD3505 at 3-1/2 inch. That lets a facility run the grouted security stops on cells, holding areas, and other high-vandalism openings while the surface bumpers stay on the rest of the doors.
