Delaney Dome Door Stop

The Delaney Dome Door Stop comes in two profiles, and the gap under your door decides it. High Profile gives 7/16 inch clearance, Low Profile gives 1/8 inch. Measure from the finished floor to the bottom of the door, then pick the profile that sits below that gap so the door swings over the stop and hits the bumper rather than dragging on it. Low Profile is the one for doors with tight undercuts or thin thresholds; High Profile suits doors set over carpet or a thicker floor covering.

A dome stop stops the door and nothing more. It takes the swing and protects the wall, then the door swings back freely. If you need the door to stay open (a propped corridor door, a loading path, a unit door during a turn), you want a holder instead: the Ives FS40 / FS41 / FS42 / FS43 automatic floor stop and holder, or the Orca Hardware 22HD Series goose neck floor stop, which is listed as a door holder. The SOSS MDH is a magnetic door holder and stop at 3-5/16 x 1-3/4 inches if you want the door held magnetically flat to the wall.

Zinc is the substrate, with a plated finish over it. That is a fit for residential and light commercial traffic: apartment unit doors, office interiors, back-of-house rooms. For a high-cycle opening, a stairwell, a school corridor, or anywhere the door gets thrown open all day, step up to a heavy duty brass stop such as the Ives FS13 or Ives FS17 floor dome stops. The FS13 carries a replaceable rubber bumper, which matters on an opening where you expect to service the stop rather than replace it.

The Orca Hardware 23LP Series is the nearest match in form and function - a dome floor stop, low rise, with a gray tip, catalogued as a door stop. The Delaney dome stop is a zinc floor stop with a 1-3/4 inch base diameter, and its low profile option gives 1/8 inch clearance, which is the same low-rise geometry the 23LP is built around. If the door bottom sits close to the finish floor, either one clears it.

A dome stop only arrests the door - it does not hold it. For hold-open, the Ives FS40 / FS41 / FS42 / FS43 automatic floor stop and holder is heavy duty and offers adjustable door-to-floor clearance, and the Orca Hardware 22HD Series goose neck floor stop is catalogued as a door holder for 1-3/8 inch or 1-3/4 inch doors. The SOSS MDH magnetic door holder and stop, 3-5/16 inch by 1-3/4 inch, is another heavy duty hold-open option where a magnet is preferred to a mechanical catch.

The dome stop stands 1-1/4 inches overall with a 7/16 inch base height, on a 1-3/4 inch diameter base. That 1-3/4 inch base is what you need against the floor plan: it wants a flat, solid landing spot clear of grout lines, transition strips, and tile edges. The low overall height keeps it under the leading edge of most swinging doors without becoming a toe catch in a corridor.

Two finishes: 626 satin chrome and 613 satin bronze oil-rubbed. Both are standard BHMA finish codes, so 626 lines up with satin chrome levers, hinges and closers elsewhere in the building, and 613 matches oil-rubbed bronze trim. Both finishes are offered in both the High Profile and Low Profile versions, so you can standardize a whole property on one finish and still vary the profile door by door as the floor clearances demand.

A floor mounted dome stop like the Delaney catches the door near the bottom rail, which is what you want when the door swings into open wall with no backing, into a baseboard you do not want punched, or where a wall bumper would land on drywall between studs. The tradeoff is the floor: you are drilling into finished flooring and leaving a 1-3/4 inch diameter base that can be a trip point in a walkway. If the door swings into a stud or solid blocking and floor obstructions are a problem, a wall stop is the cleaner choice. For a low visual footprint on the floor, the Low Profile version at 1/8 inch clearance sits closest to the deck.

Shape drives what each one does. The Delaney dome is a low round stop, 1-1/4 inches tall on a 1-3/4 inch base, that the door contacts at the bottom edge and then releases. A goose neck stop, like the Orca 22HD Series or the Emtek 2253, stands taller on a curved post and reaches the door higher up, and the Orca version is listed as a holder rather than a plain stop. A cylindrical floor bumper, such as the Emtek 2257 at 1-1/2 inches or the Sure-Loc cylindrical floor stop, is a straight post rather than a dome. Pick the dome when you want the least amount of hardware standing up off the floor.

The Delaney dome sits on a 1-3/4 inch diameter base, which is wide if you are trying to land it inside a single tile or clear of a grout line. Smaller footprints in the same family of floor bumpers: the Deltana UFBS138 square universal floor bumper at 1-3/8 inches, the Emtek 2254 floor door bumper at 1-3/8 by 1-1/4 inches, the Deltana UFB4505 round universal bumper at 1-1/2 inches, and the Deltana UFBP4505 with a pattern cap at 1-5/8 inches. If you want a larger decorative base instead, the Deltana UFBD3505 runs 3-1/2 inches.

No handing to specify. A floor dome stop is a symmetrical round puck mounted to the floor on a 1-3/4 inch base, so it works the same on a left hand or right hand door and on an in-swing or out-swing. The only two choices you make when ordering are finish (626 satin chrome or 613 satin bronze oil-rubbed) and profile (7/16 inch or 1/8 inch clearance). What you do have to get right is placement: set it so the door contacts the bumper before the lever or the door face reaches the wall.

It covers the same job with a different body material. The Delaney dome stop is zinc with a 1-3/4 inch base diameter. In solid brass, the Deltana UFB4505 round universal floor door bumper is 1-1/2 inch and the Deltana UFBP4505 round universal floor door bumper with pattern cap is 1-5/8 inch - both close to the Delaney footprint. The Deltana UFBD3505 round universal floor bumper is a decorative 3-1/2 inch solid brass unit, a much larger footprint on the floor.

They share the dome silhouette but are separate parts. The Emtek 2251 is a half dome door stop and Emtek also lists the 2254 floor door bumper at 1-3/8 inch by 1-1/4 inch. The Delaney Dome Door Stop is zinc, 1-3/4 inch base diameter, 1-1/4 inch overall height, and comes in two profiles: high with 7/16 inch clearance and low with 1/8 inch clearance. Match on base diameter and required clearance rather than on the dome shape alone.

The Delaney dome is a standard zinc floor stop, which suits units, offices, and interior openings. For a location where tampering is the concern (a detention area, a school, a public restroom, a lobby door that gets abused), look at the Ives FS18S/FS18L security floor stop, a heavy duty stop built for that situation. For a high-traffic opening that is not a security concern but sees constant use, the heavy duty brass Ives FS13 or FS17 dome stops are the closer match.

Yes, and that is the usual way to buy it on a multi-door job. All four combinations exist: 626 satin chrome in High Profile and in Low Profile, and 613 satin bronze oil-rubbed in High Profile and in Low Profile. So a property manager standardizing a building on 626 can order High Profile for the doors sitting over carpet and Low Profile for the tight-clearance openings without breaking finish consistency across the property.

Yes - the Deltana UFBS138 is a square universal floor door bumper at 1-3/8 inch in solid brass, which lines up with square rosettes and modern trim. The Sure-Loc DS-FL1 floor stop is offered with spring and modern door stop designs. The Delaney Dome Door Stop is round, a 1-3/4 inch diameter zinc dome.
