Ives CS115 Heavy-Duty Crash Stop with Steel Chain for Full-Size Exterior Doors

Professional Door Protection for Exterior Commercial Applications

The Ives CS115 Crash Stop is engineered for full-size exterior doors where a standard floor stop won't hold. Cast brass end brackets and a solid welded steel chain absorb door impact and hold the door at its travel limit: no wall damage, no door damage. Heavy-duty compression springs at both ends of the chain and at the end brackets cushion the stop and return the chain to position. A tear-resistant grey vinyl sleeve protects the chain and maintains a clean appearance in high-traffic corridors, lobbies, and building entries.

Key Features

  • Cast Brass Brackets: Corrosion-resistant, heavy-duty construction suited for exterior and high-humidity environments.
  • Solid Welded Steel Chain: Rated for full-size exterior door loads; chain does not stretch or deform under repeated impact.
  • Dual Compression Springs: Assembled to both ends of the chain and end brackets for consistent, cushioned door control.
  • Tear-Resistant Grey Vinyl Cover: Protects chain and internal components; maintains professional appearance over time.
  • Sex Bolt Mounting Option: Available in 626 (Satin Chrome) finish for tamper-resistant installation in public or high-security areas.
  • Packed with Sheet Metal Screws: Ready for immediate installation, no additional hardware required.
  • ANSI/BHMA 156.16 Compliant: Meets the commercial door hardware standard for door stops and holders.

Installation Notes

Mount the floor bracket at the desired door-travel limit using the included sheet metal screws. Attach the chain end brackets to the door bottom and floor bracket. Adjust chain tension via the compression springs so the door stops firmly without slamming. For tamper-resistant installations, use the sex bolt mounting option (626 finish). Refer to the Ives Full Line Catalog for template dimensions and torque specifications.

Why Ives CS115?

Ives has been a trusted name in commercial door hardware for decades. The CS115 is built to the same standard as the rest of the Ives line, with heavy material, tight tolerances, and compliance with ANSI/BHMA 156.16, so it performs reliably in the applications where a failed door stop means a damaged wall, a damaged door, or a liability claim. Two finishes and three chain lengths mean you can match the door hardware schedule and the door width without a custom order.

Ives CS115-US26D-25 – Frequently Asked Questions

1) How do I pick between the 20.5, 25.5 and 30.5 inch chain lengths on the Ives CS115 crash stop?
Chain length is what sets how far the leaf swings before the stop takes the load, so pick it off the door width and the point you want the door caught. The CS115 chain comes in 20.5, 25.5 and 30.5 inches, and every length is offered in both finishes, 613 satin bronze oil-rubbed and 626 satin chrome. A wide entry leaf that needs to open most of the way takes the 30.5; a vestibule or a corridor entry where the door has to be caught early takes the 20.5. Measure from the mounting point on the door bottom to where the floor bracket can land and order the chain that reaches it.
2) Do I need a chain crash stop like the Ives CS115, or is a floor bumper enough for my door?
It comes down to the weight of the door. A floor bumper, say the Deltana UFB4505 at 1-1/2 inches or the Emtek 2254 at 1-3/8 by 1-1/4 inches, sits in the swing path and cushions the leaf at one fixed landing point. That handles a normal interior door. The CS115 is built for full-size exterior doors where a floor stop won't hold: a solid welded steel chain runs between the door and a floor bracket and takes the load at the travel limit, with heavy compression springs at both ends of the chain and at the end brackets absorbing the hit. If the door is a full-size exterior leaf, or it catches wind at a building entry, the chain is what stops it without damaging the wall or the door.
3) Will the Ives CS115 hold an entry door open, or does it only stop it?
It stops the door, it does not hold it. The CS115 chain catches the leaf at its travel limit and the compression springs cushion the stop and pull the chain back into position, so nothing parks the door in the open position. If what you actually need is a door held open for deliveries or move-ins, that is a different part: the Orca Hardware 22HD Series gooseneck is listed as a door holder, and the SOSS MDH is a magnetic door holder and stop at 3-5/16 by 1-3/4 inches. Plenty of entries get both, a holder for when the door needs to stay open and a crash stop for when it doesn't.
4) Is a gooseneck floor stop the same thing as an Ives CS115 crash stop?
No. A gooseneck stop such as the Delaney Gooseneck Floor Door Stop, the Emtek 2253 Goose Style Door Stop, or the Orca Hardware 22HD Series Goose Neck Floor Stop with black tip is a single post anchored to the floor that the door face contacts at a fixed point in its swing. The Ives CS115 works the other way: cast brass end brackets on the door and the floor are tied together by a solid welded steel chain, with compression springs at both ends of the chain and at the end brackets to cushion the door and return the chain to position. The chain restrains the door at its travel limit rather than presenting a post for it to hit, which is why the CS115 is specified for full-size exterior doors where a standard floor stop will not hold.
5) I need the door to stay open, not just stop. What is the alternative to the Ives CS115?
The Ives CS115 arrests the door at its travel limit and the compression springs return the chain to position, so it controls the swing rather than parking the door open. For a hold-open, the Orca Hardware 22HD Series goose neck floor stop is specified with a door holder function, and the SOSS MDH is a magnetic door holder and stop at 3-5/16 inch by 1-3/4 inch rated heavy duty. Buyers on entry doors frequently run both: a holder to park the leaf during deliveries and a crash stop to catch it when it is released.
6) Where does the Ives CS115 crash stop mount, and does it come with the screws?
Two mounting points: a floor bracket set at the door's travel limit, and a chain end bracket fastened at the bottom of the door. Sheet metal screws are packed with it, so a standard install needs nothing else from the counter. Once both brackets are in, set the tension at the compression springs so the door comes to a firm stop instead of hitting the end of the chain hard. Worth checking your floor material before you schedule the work, since the included fasteners are sheet metal screws.
7) Is there a tamper-resistant mounting option for the Ives CS115 in a public lobby or school entrance?
Sex bolt mounting is available, and it is tied to one finish: the 626 satin chrome version. Specify that one for lobbies, school entries, correctional and municipal work, or anywhere the hardware sits within reach of the public and screw heads are a target. The 613 satin bronze oil-rubbed version goes in with the included sheet metal screws. Both finishes run in all three chain lengths, so choosing 626 for the sex bolt option does not limit which length you can get.
8) Will the Ives CS115 crash stop hold up on an exterior entrance exposed to weather and humidity?
That is the application it is built for. The end brackets are cast brass, corrosion resistant and suited to exterior and high-humidity environments, and the chain is solid welded steel that does not stretch or deform under repeated impact. Substrate is brass and steel throughout, so there is no plastic or die-cast body to fail in the sun. The chain carries a tear-resistant grey vinyl sleeve, which keeps grit off the links and keeps the assembly looking clean in a lobby or a building entry rather than turning into exposed bare chain after a season.
9) Does the Ives CS115 crash stop meet ANSI/BHMA for a commercial hardware schedule?
The CS115 is compliant with ANSI/BHMA 156.16, the commercial standard covering door stops and holders, and it is a commercial-grade product rather than a residential one. That is the line item a spec writer or an institutional buyer needs when the stop has to appear on the hardware schedule for a school, hospital, or government building. Two finishes and three chain lengths mean one specified part number covers entries of different widths across the same facility.
10) I am ordering stops for 1-3/4 inch commercial doors. Which of these is sized by door thickness?
The Orca Hardware 22HD Series goose neck floor stop is the one specified by door thickness, listed for 1-3/8 inch or 1-3/4 inch doors, because the post is sized against the leaf it meets. The Ives CS115 is ordered by chain length instead, in 20.5, 25.5 and 30.5 inch, since the chain spans from a bracket at the door bottom to a bracket on the floor and the length that matters is how far you want the door to travel before it is caught.
11) The lobby is carpeted and I want the lowest profile floor stop I can get. What are my options against the Ives CS115?
For a low silhouette, the Orca Hardware 23LP Series is a dome floor stop, low rise, with a gray tip and a door stop function, and the Delaney Dome Door Stop and Emtek 2251 Half Dome Door Stop use the same low dome shape. Those sit as a single low pad on the floor. The Ives CS115 runs a chain in a tear-resistant grey vinyl sleeve between a bracket at the door bottom and a bracket on the floor, so plan for that chain path across the floor at the door opening.
12) For an exterior door in a humid coastal building, how does the Ives CS115 compare to the brass floor bumpers?
The Ives CS115 is a brass and steel assembly: cast brass end brackets described as corrosion-resistant and suited to exterior and high-humidity environments, with a solid welded steel chain under a vinyl cover. The Deltana UFB4505 at 1-1/2 inch, the UFBS138 square at 1-3/8 inch, the UFBD3505 at 3-1/2 inch and the UFBP4505 at 1-5/8 inch are all solid brass throughout. The difference to weigh is function rather than material - the Deltana pieces are floor bumpers the door contacts, while the CS115 is a chain restraint carrying the load of a full-size exterior door at its travel limit.
13) Tenants keep unscrewing the door stops in our building entry. What holds up better, the Ives CS115 or a floor bumper?
The Ives CS115 is offered with a sex bolt mounting option in the 626 satin chrome finish for tamper-resistant installation in public or high-security areas, and it ships packed with sheet metal screws for standard mounting. Among the floor-mounted alternatives, the SOSS MDH magnetic door holder and stop is rated heavy duty, and the Deltana UFB series bumpers such as the UFB4505 and the square UFBS138 are solid brass units anchored at the floor. If the concern is specifically that fasteners get backed out by hand, the sex bolt option is the detail to specify on the CS115.
14) My building is all 626 satin chrome hardware. What is the right Ives CS115 part number to match?
626 satin chrome, the US26D finish, is one of the two the CS115 is made in, so it drops straight into a 626 schedule. The other is 613 satin bronze oil-rubbed, US10B, for dark bronze entries. The part number carries the finish code and the length: CS115-US26D-25 is 626 with the 25.5 inch chain, CS115-US10B-25 the same length in bronze. Base model is CS115 in every case. Since both finishes run in all three lengths, you can keep one finish across doors of different widths without ordering anything special.
15) I'm standardizing door stops across a whole building. Where does the Ives CS115 belong and where is a simpler floor stop the right call?
Put the CS115 on the full-size exterior leaves, the main entries, corridor doors off the entry, loading and service doors, anything heavy enough that a floor stop gets knocked loose or the wall takes the hit. Inside the building, where the door only needs a landing cushion, a floor bumper does the job: the Deltana UFBS138 square bumper at 1-3/8 inches, the Emtek 2251 half dome stop, or the Orca Hardware 23LP low-rise dome, which is listed as a door stop. Splitting the schedule that way keeps the heavy chain assembly where the impact actually is, and the CS115 comes in 613 and 626 so the exterior stops still match the finish running through the rest of the building.
16) What is a more decorative option than the Ives CS115 for a finished entry?
Deltana offers decorative floor bumpers in solid brass: the UFBD3505 is a 3-1/2 inch round decorative bumper and the UFBP4505 is a 1-5/8 inch round bumper with a pattern cap. Both present as a finished brass piece at the floor. The Ives CS115 reads as commercial hardware by design, with cast brass end brackets and the steel chain carried in a grey vinyl sleeve, in 613 satin bronze oil-rubbed or 626 satin chrome.
17) Round or square floor bumper, and does it matter next to an Ives CS115?
Deltana carries both shapes in solid brass: the UFB4505 is round at 1-1/2 inch and the UFBS138 is square at 1-3/8 inch, and Emtek offers the 2257 as a 1-1/2 inch cylindrical bumper and the 2254 at 1-3/8 inch by 1-1/4 inch. Shape there is an appearance and footprint choice against the floor material. It does not carry over to the Ives CS115, which is not a bumper the door strikes but a chain and bracket assembly with compression springs that catches the door at its travel limit.
