Deltana DSM125 Magnetic Dome Door Stop

The Deltana DSM125 does both. It's a floor-mounted dome stop with a magnet, so the door swings into it, stops, and then stays held open against the magnet until someone pulls it free. That's the difference between it and a plain rubber-tipped dome bumper, which stops the swing but lets the door drift back. If you only need the wall or door face protected and don't care about hold-open, a plain bumper like the Emtek 2254 floor door bumper or the Orca 23LP low-rise dome floor stop does that job.

For hold-open alone, yes. The DSM125 magnetic dome stop is a cheaper, far simpler way to park a door in the open position than hanging a closer on it, and Deltana positions it exactly that way. What it will not do is control the door on the way back, so if the opening needs the door returned and latched on its own (fire door, stair door, anything on a closer schedule), the magnetic stop is not a substitute for the closer. Plenty of jobs use both: closer for the return, magnetic stop for the hold.

Depends how far the door swings and how the floor is finished. A dome stop like the DSM125 sits low and close to the door, so it needs to land where the door edge reaches it, and the magnet then holds the door there. A gooseneck stop stands up off the floor on a post and catches the door higher, which is what you use when the door needs to open wider than a dome stop's position allows or when the strike point has to clear a base shoe. Gooseneck options include the Delaney gooseneck floor door stop, the Emtek 2253 goose style stop, and the Orca 22HD gooseneck floor stop, which Orca lists as a door holder rather than a plain stop.

That's the thing to check before ordering the DSM125. A magnetic dome stop is floor-mounted and low profile, so the magnet has to meet a catch plate on the bottom of the door for the hold to work. Thick carpet, a raised transition strip, or an undercut door with a large floor clearance can put the two out of reach of each other. Where the door-to-floor clearance is the problem, the Ives FS40 / FS41 / FS42 / FS43 automatic floor stop and holder is built with adjustable door-to-floor clearance for exactly that condition.

The SOSS MDH is the nearest match. It is a magnetic door holder and stop measuring 3-5/16 inches by 1-3/4 inches, and like the DSM125 it both stops the door and magnetically holds it open. The Deltana DSM125 is a solid brass magnetic dome stop offered in eleven finishes including polished brass, oil rubbed bronze, brushed nickel, polished chrome and brushed stainless, so if the finish has to match other trim on the opening the DSM125 gives the wider selection; if the specification calls out a heavy duty holder, the SOSS MDH is rated heavy duty.

Go to a gooseneck or an automatic floor stop. The Ives FS40, FS41, FS42 and FS43 are heavy duty automatic floor stops and holders with adjustable door-to-floor clearance, which is the direct answer when the gap under the door is larger than a low dome can reach. The Orca Hardware 22HD gooseneck floor stop with black tip is a door holder built for 1-3/8 inch or 1-3/4 inch doors, and the Delaney Gooseneck 40118X and Emtek 2253 Goose Style stop are the same tall riser shape. The Deltana DSM125 is a dome profile that sits low on the floor and takes the door on a magnetic face, so it needs the door bottom close to the floor.

Yes. The Ives FS13 and FS17 are both heavy duty brass floor dome stops, the FS13 with a replaceable rubber bumper and the FS17 with a rubber bumper. A replaceable bumper matters on an opening that gets hit all day, because the maintenance item is the tip and the FS13 lets it be changed without pulling the base. The Deltana DSM125 is solid brass and designated for commercial use, and holds the door open magnetically, which the Ives dome stops do not do.

Deltana classes the DSM125 as commercial. It's solid brass rather than a zinc or plated pot-metal body, which is what you want on an opening that gets worked all day. For high-traffic commercial door stops from other lines, the Ives brass floor dome stops (FS13 and FS17) are catalogued as heavy duty, and the Ives FS18S/FS18L security floor stop is the heavy-duty pick where the stop itself gets abused or kicked.

Eleven finishes, which is why it matches out across a building better than most stops: Polished Brass, PVD Polished Brass, Antique Brass, Oil Rubbed Bronze, Brushed Nickel, Antique Nickel, Polished Chrome, Brushed Chrome, Polished Stainless, Brushed Stainless, and Paint Black. The PVD polished brass is the one to specify where the stop sits in a lobby or an exterior vestibule and you don't want the brass to tarnish, since PVD is a hard coating rather than a lacquer.

Mounting hardware ships with it. Each DSM125 magnetic dome stop is bagged individually with its mounting hardware, and it's sold and priced per piece, so ordering ten stops for ten openings gets you ten complete stops. Fasteners supplied with a floor stop suit the fixing they're specified for, so on concrete slab or tile you may still want your own anchors.

A plain floor bumper. The Emtek 2254 floor door bumper is 1-3/8 inches by 1-1/4 inches, and the Emtek 2257 is a 1-1/2 inch cylindrical floor bumper. Both are simple pucks that take the impact and nothing more, with no magnet and no holding action. The Emtek 2251 half dome stop is the other low option, a half dome rather than a full dome shape. The Deltana DSM125 is a magnetic dome stop and comes packed with its mounting hardware in an individual poly bag, so it is the choice only where the door needs to be held open as well as stopped.

No, they solve a different problem. The Ives FS18S and FS18L are heavy duty security floor stops, built for openings where the stop itself has to resist tampering or abuse. The Deltana DSM125 is a solid brass magnetic dome stop whose purpose is holding a door at the open position without a door closer. If the requirement is a secure floor stop in a detention, behavioral health or back-of-house corridor, the FS18S or FS18L is the correct part, and it will not hold the door open; if the requirement is hands free hold open, the DSM125 is.

The Deltana DSM125 is offered in eleven finishes, including polished brass, PVD polished brass, antique brass, oil rubbed bronze, brushed nickel, antique nickel, polished chrome, brushed chrome, polished stainless, brushed stainless and paint black, so one part number covers a building where the lever and hinge finish varies by wing or by floor. Among the dome stop comparables, the Orca Hardware 23LP low rise dome stop comes with a gray tip and the Ives FS13 and FS17 are brass floor dome stops. The DSM125 is solid brass and adds the magnetic hold open, which the other dome stops do not carry.

Solid brass, listed both as the material and the substrate, not a plated finish over zinc. On a floor stop that matters more than it does on decorative trim, because the part gets kicked, mopped, and struck by the door edge. A plated pot-metal stop chips at the strike point and shows the base metal; a solid brass body wears without exposing anything different underneath. For maintenance buyers standardizing across a property, that's the reason to pay for brass here.

Finish is the only choice to make. The DSM125 is one model in eleven finishes, sold each, so a purchase order is quantity plus finish and nothing more. No handing, no size, no left or right hand version. Mounting hardware is in the bag, so nothing separate is needed to complete a standard install.
