Deltana BDSS40 4" Modern Square Baseboard Bumper, Solid Brass

The Deltana BDSS40 is a 4 inch baseboard bumper with a 7/16 inch tip projection, so the door comes to rest roughly 7/16 inch off the baseboard face and never touches the trim. The 4 inch body spreads that impact along the baseboard instead of loading one small point. If the opening needs the door held further off the wall than 7/16 inch, this is not the stop for it.

A baseboard bumper only works where there is baseboard behind the arc of the swing. The BDSS40 mounts flat to that baseboard and takes the door on a 7/16 inch tip. When the door swings out over open floor, or the wall behind it sits past the leaf, you want a floor mount instead, and the Delaney 2 inch round solid brass floor bumper is that part. If you want some give at the strike rather than a dead stop, the Orca Hardware 3-1/8 inch and 3-3/4 inch spring door stops flex on contact; the Deltana bumper is rigid.

Deltana classifies the BDSS40 as residential. On a house, an apartment interior, or a light office door it is the right weight of part, and the solid brass body will take that duty. For openings absorbing real traffic, step up to a rigid stop: the Orca Hardware TH-30HD HD rigid door stop, or the Hager 212 adjustable rigid door stop, which sets the stopping point anywhere in an 80 to 120 degree range.

The Emtek 2231 is also a 4 inch baseboard door stop, so it mounts to the same trim run and spans the same length of baseboard. The Deltana BDSS40 is 4 inches long in solid brass with a 7/16 inch tip projection, and it comes in Oil Rubbed Bronze, Polished Nickel, Brushed Nickel, Polished Chrome, Unlacquered Brass, Brushed Brass and Paint Black. With the length and the mounting surface the same, finish matching to the rest of the door hardware is usually what decides between the two.

The Delaney 40201X is a solid brass baseboard door stop that adjusts from 3-1/2 inches to 4-1/2 inches, so a single part number covers openings whose trim sits at different heights. The Deltana BDSS40 is a fixed 4 inch square bumper in solid brass, which suits a building where the trim run is consistent and the strike point lands at the same height on every opening. On a mixed-trim property the adjustable body saves carrying two sizes; on a uniform trim run the fixed 4 inch square keeps the profile identical at every door.

It only stops. The BDSS40 is a bumper, it absorbs the swing and nothing else. There is no catch, hook or friction arm to keep the leaf standing open. For an opening that has to stay propped, the Orca Hardware TH-30HD HD rigid door stop is carried as a door holder rather than a bumper.

Oil Rubbed Bronze is one of seven finishes on the BDSS40 4 inch square baseboard bumper. The complete run is Oil Rubbed Bronze, Polished Nickel, Brushed Nickel, Polished Chrome, Brushed Brass, Unlacquered Brass, and Paint Black. Because the model itself is a fixed 4 inch length, you can standardize one bumper across every door in a building and vary only the finish unit to unit.

Solid brass, and the substrate is brass as well, not a plated pot metal casting wearing a brass color. That matters more on a bumper than on most trim because the tip takes the same hit over and over. A cast zinc body chips at the strike point and the finish leaves with it; brass deforms rather than fractures.

The BDSS40 is fixed at 4 inches, there is no adjustment built into it, so it either reaches or it does not. Where you cannot pin the reach down on paper before ordering, the Delaney solid brass baseboard door stop adjusts from 3-1/2 to 4-1/2 inches and takes up the slack a fixed length will not.

Not by itself. A baseboard bumper catches the door down at the baseboard, and the BDSS40's tip holds it 7/16 inch off at that height. A knob or lever sits well up the door and projects considerably further off the face than 7/16 inch, so if the handle is what is marking the wall, either the bumper has to sit where the door face reaches it before the handle reaches the wall, or you need a wall stop set at handle height. Measure the handle projection first.

It works only if the door leaf reaches the floor bumper before the lever or knob reaches the wall. The Delaney 4029XX is a 2 inch high round solid brass floor bumper that fastens to the floor in the swing path. The Deltana BDSS40 fastens to the baseboard and takes the strike at trim height, with a 7/16 inch tip projection setting how far the leaf stands off the wall. Floor mounting leaves the wall and trim untouched but puts a fixed obstruction in the walking path and has to be re-set if the floor covering changes; baseboard mounting keeps the floor clear and puts the fastener into the trim.

The two do different jobs. The Orca TH-30HD is a heavy duty rigid door stop whose function is a door holder, so it arrests the swing and holds the leaf open at that point until it is released. The Deltana BDSS40 is a 4 inch solid brass baseboard bumper that stops the leaf against the trim and leaves it free to swing back closed. If the opening needs a door parked open for carts, moving or ventilation, the holder is the part to order; if the requirement is protecting the wall and trim from the knob or lever, the bumper is.

A spring stop absorbs the swing by flexing along its body. Orca builds spring door stops at 3-1/8 inches (TH-3118) and 3-3/4 inches (TH-3134), both carrying a door stop function. The Deltana BDSS40 is a rigid 4 inch solid brass bumper with a 7/16 inch tip projection that fastens to the baseboard and does not give. The spring body forgives a hard or wind-driven swing and returns; the rigid brass body arrests the leaf at a fixed point and carries a finished trim appearance in Oil Rubbed Bronze, Polished Chrome, Brushed Nickel and the other finishes it is made in.

No, and that is what unlacquered brass is for. There is no clear coat holding the color, so it darkens and takes on a patina from air and handling. On a bumper it does something specific: the door strikes the same spot repeatedly, so the contact area stays brighter while the rest of the body ages around it. If you want an even, unchanging look across a run of doors, specify one of the other six finishes instead.

The Hager 212 is an adjustable rigid door stop with an 80 to 120 degree range, so the angle at which the leaf is arrested can be dialed in within that band, which is what a contractor reaches for when a door has to be kept off adjacent millwork or equipment. The Deltana BDSS40 stops the leaf wherever it is fastened along the baseboard, and its 7/16 inch tip projection sets how far the door stands off the wall at contact. The BDSS40 is specified for residential use and made of solid brass.
