A brass door stopper is a small solid brass fitting that catches a door before its edge, handle or hinge reaches a wall, and Studio Timeless makes five of them: three that mount to the floor, two that mount to either floor or wall, and one weighted body that needs no fixing at all. Prices run from $29.90 to $40.90 per piece, and every model carries a rubber bumper.
In short
- Five active models, all solid brass, all supplied with a rubber bumper and screw fittings.
- Two body sizes: a low 25 to 35 mm profile for discreet floor work, and a 100 mm body for doors that swing hard.
- Four finishes: Antique Brass, Brass, Black and Nickel, with Nickel carrying a $2 to $3 surcharge on two models and not offered on the freestanding body.
- One model only, the Solid Brass Door Stopper, is described for outdoor as well as indoor use.
- Price is per piece, not per door. A twelve door house is twelve stoppers, not one order line.
- No door stopper of any kind belongs on a fire rated door assembly.
A door stopper protects three things, and only one of them is the wall
The obvious job is keeping a door handle out of the plaster. The two that matter more over twenty years are the door and the hinge. A lever or a long pull that hits a wall drives the whole swinging mass of the slab into one point on the stile, and the stile is where it cracks. A door that stops by slamming unloads that impact back through the hinge leaves into the screws, which is one of the quiet ways a door starts to sag. On a heavy slab the stopper belongs in the same calculation as the solid brass butt hinges, and our hinge sizing guide explains why the jamb fixing carries so much of the load.
The five Studio Timeless door stoppers, side by side
All five are machined from solid brass rather than plated zinc, the difference you feel in the hand and see in ten years. The table is read from the live catalogue today.

The door stopper collection sits inside the wider brass hardware range, where the finish language has to stay consistent across a house.
Projection decides more than mounting style
The most useful distinction in the range is not where it fixes, it is how far it stands out. The 25 to 35 mm bodies sit low and catch a door gently, close to the wall, which suits light interior doors. The 100 mm bodies take the hit earlier in the swing, which is what a heavy slab needs, or a door carrying a long classical pull handle that projects past the face. Choosing the small body where the big one was needed is the most common mistake we see, and it shows up as a permanently compressed bumper.
Floor, wall or freestanding: how to choose
Decide by what the door hits first, then by what you are allowed to drill into.
| Situation | Use | Why |
|---|---|---|
| Door handle strikes a plain plaster wall | Wall mount, 100 mm body | Catches the door at the point of impact rather than at the floor |
| Door swings back against a radiator, skirting or furniture | Floor mount | The obstruction is below handle height, so the stop has to be too |
| Uneven, sloping or thick rug floor | Adjustable height floor mount | Up to 3 cm of adjustment absorbs the level difference |
| Rented, listed or stone floor you cannot drill | Freestanding weighted body | No fixing, no hole, fully reversible |
| Exterior door, gate, porch | Solid Brass Door Stopper, heavy duty | The only model in the range described for outdoor use |
| Fire rated door assembly | None of them | See the fire door section below |
Where the stop actually goes on the floor
Put the stopper where the door reaches it at the end of a comfortable swing, not at the extreme limit of travel. Open the door to where you want it to rest, mark the floor at the leading edge, then set the stopper so the bumper meets the face of the door rather than its edge, because catching the thin edge of a slab concentrates the load on a few millimetres of timber. Keep it out of the walking line: a low brass body mid doorway is a toe catcher.
Mounting height for a wall stop, and the protruding object rule
A wall mounted stop should meet the door at the height of whatever strikes, in most houses the lever or the pull, roughly 36 to 40 inches above the floor. Lower and the door pivots over it; higher and you are fixing into the weakest part of the plaster.
In any space covered by the ADA Standards, section 307.2 limits objects with leading edges between 27 and 80 inches above the floor to a 4 inch projection into a circulation path. Our 100 mm body measures 3.93 inches, under that limit, but what counts is the installed assembly on your wall, and on a commercial or multifamily project the US Access Board standards and your building department have the final word.
Fixing into wood, tile and concrete
Every model ships with screw fittings, and the fixing is the part people get wrong. Into timber, drill a pilot matching the screw's core and let the threads bite into solid material rather than a finish layer. Into engineered board or a floating floor, the fixing has to reach the substrate, otherwise it pulls the plank up on the first hard swing.
Tile is the case that ruins floors. Drill glazed tile at low speed with a tile or diamond bit, masking tape on the surface to stop the bit wandering, never on hammer action, and keep the hole in the body of a tile rather than near a corner or grout line. In concrete or screed, use a plug sized for the fixing supplied. If you are unsure what is beneath, our installation and compatibility guide is the place to start, and on stone or terrazzo go freestanding instead.
The freestanding case, and what it is honestly good for
The Brass Freestanding Door Stopper at $29.90 is the lightest commitment in the range, the only one that leaves no hole, and it can still be screwed down later. It suits rentals, floors you are not willing to drill, and a period house where you want the decision reversible. What it is not is a wedge: it stops a door at a fixed point, it will not hold a door open against a closer or a draught, and it will skid if a heavy door is thrown at it.
The one model given for outdoor use
Only the Solid Brass Door Stopper, Heavy Duty is described in our catalogue for indoor and outdoor doors and gates; the rest are specified for interior use. Brass outdoors behaves differently: salt air, rain and UV accelerate patina, and a lacquered finish exposed to weather eventually breaks down at the edges. Choose Antique Brass if you want the exterior piece to darken rather than flake, and expect it visibly deeper than its indoor twin within a season.
Finishes, and how they line up with the rest of the house
The door stopper range runs four finish names: Antique Brass, Brass, Black and Nickel. That vocabulary does not map one to one onto the eight names used across our electrical range, the same mismatch we documented for the butt hinges. There is no unlacquered option on door stoppers, so if your switches are specified in Unlacquered Antique Brass, which is made to order and not returnable, the stopper will not age in step with them.
Two pricing details matter before you build a schedule. Nickel costs $3 more on the adjustable model and $2 more on the heavy duty model, nothing extra on the two 100 mm bodies, and is not offered on the freestanding body. For one finish across every stopper in a house, Antique Brass, Brass and Black run across all five models. On keeping metals consistent from the switch plates to the cabinetry, our guide to the eight Studio Timeless finishes sets out which families are lacquered and which are living, the 2026 trends piece covers the brass and black pairing, and the metallurgy is set out by the Copper Development Association.
Fire rated doors: never
A fire door assembly has to be self closing and self latching, and nothing may obstruct that. Fire marshal guidance is explicit that propping a fire door with a wedge, a tie back or a block puts the building at risk, and that the only acceptable way to hold one open is an electromagnetic device that releases when the fire alarm activates. The National Fire Protection Association publishes the requirements behind that rule.
The hardware standard says the same from the other direction. ANSI/BHMA A156.16, which covers auxiliary hardware including door stops and holders, carries the explicit caution that use of some products described in it "on doors within a means of egress or fire door assemblies are regulated by authorities having jurisdiction". Our door stoppers are decorative solid brass fittings. They carry no fire rating and we do not claim one. On a rated opening, ask the authority having jurisdiction first; the scope is published in the ANSI/BHMA preview.
What a door stopper will not fix
If a door drifts shut, swings open on its own, or binds on the latch side, a stopper is the wrong tool. Drift is almost always a hinge or frame fault: a door out of plumb, hinges set at different depths, or screws that never reached structural timber, all covered in our hinge guide. A stopper placed to hide a hanging fault only moves the symptom.
Counting for a whole house, and the pricing trap
Every listing on our site sells one door stopper, and the per piece price multiplies faster than people expect.
| Scope | Pieces | At $29.90 | At $34.90 | At $40.90 |
|---|---|---|---|---|
| One bathroom and one bedroom | 2 | $59.80 | $69.80 | $81.80 |
| Typical three bedroom house | 8 | $239.20 | $279.20 | $327.20 |
| Twelve door house | 12 | $358.80 | $418.80 | $490.80 |
Not every door needs one. Doors opening into a reveal, into a corner, or against a run of cabinetry often stop themselves, so mark only the swings that reach something. On a specified project our trade programme is the sensible route, and the same logic applies to the cabinet hardware schedule, usually the larger line.
What we see at the service desk
Three patterns come up repeatedly. A 25 mm body ordered for a heavy slab that needed the 100 mm one. Finish drift, where a stopper in Brass sits near switches in Unlacquered Antique Brass and the two diverge within months, because one finish is stable and the other is not. And a fixing taken into a floating floor rather than through to the substrate, which fails on the first hard swing and lifts a plank with it. If you are unsure, send us a photo of the swing and the floor and we will tell you which body size to use.
Frequently asked questions
What is a door stopper for?
It catches a door at a set point in its swing so the handle, the slab edge or the hinge does not drive impact into a wall, a radiator or furniture. The wall is the visible beneficiary; the door and its hinges last longer for it.
Do door stops go on the wall or the floor?
Wall if the handle strikes clear wall at handle height. Floor if the obstruction is low, if the wall will not take a fixing, or if the door swings against furniture. Two of the five Studio Timeless models do either.
How high should a wall mounted door stop be?
At the height of whatever strikes first, typically the lever or pull, roughly 36 to 40 inches above the finished floor. In regulated spaces check the projection against ADA 307.2.
Where exactly do you put a door stopper on the floor?
Open the door to where you want it to rest, mark the floor at the leading edge, and set the stopper so the bumper meets the face of the door, not its thin edge. Keep it out of the walking line.
Are door stops necessary?
Not on every door, but on any swing that reaches a wall, a radiator, a cabinet run or furniture. Doors opening into a reveal or a corner usually stop themselves.
Can you use a door stop on a fire door?
No. A fire door assembly must remain self closing and self latching, and may only be held open by an approved device that releases on the fire alarm. Decorative door stoppers carry no fire rating.
What is a freestanding door stopper?
A weighted solid brass body that sits on the floor unfixed. It stops a door at a set point and leaves no hole, which suits rentals and floors you will not drill. It is not a wedge and will not hold a door open.
How do you fix a door stop into tile?
Mask the spot, drill at low speed with a tile or diamond bit, never on hammer action, and keep the hole in the body of a tile rather than near a corner or grout line. Then plug and fix. If you only get one attempt, use the freestanding model.
What finishes do the brass door stoppers come in?
Antique Brass, Brass, Black and Nickel across most of the range; the freestanding model omits Nickel. There is no unlacquered option, so they will not age in step with unlacquered switches or plates.
Is a brass door stopper suitable for outdoor use?
Only the Solid Brass Door Stopper, Heavy Duty, is described for indoor and outdoor doors and gates; the others are specified for interior use. Expect brass left outdoors to darken considerably faster than the same piece indoors.
What is the difference between the 35 mm and the 100 mm bodies?
Projection. The small bodies sit low and catch the door close to the wall, which suits light interior doors. The 100 mm bodies stand proud and take the impact earlier, which is what heavy slabs and long projecting pulls need.
How many door stoppers does a house need?
One per swing that actually reaches something. A twelve door house rarely needs twelve, so walk the plan rather than guessing: our listings are priced per piece.
Choosing well, once
Pick the projection first, the mounting second and the finish third, and a door stopper becomes a fitting nobody thinks about again. Browse the five models in the door stopper collection, or see them alongside the brass butt hinges and the rest of the Studio Timeless hardware range. Studio Timeless makes solid brass hardware to order in the United States, in a finish language that runs from the door through to the wall plate.
