Deltana BDSR40 4" Contemporary Half-Cylinder Tip Baseboard Bumper, Solid Brass

No. The BDSR40 is a residential-rated bumper, built for house and apartment interior doors. For a commercial corridor, a school, or anywhere the door gets thrown open hard all day, use a heavy duty rigid stop or holder such as the Orca Hardware TH-30HD, or a Hager 212 adjustable rigid stop, which stops the door at a set angle instead of relying on a small brass tip against the trim.

The Deltana BDSR40 is a fixed 4 inch bumper, so every unit lands at the same reach. Across a building with mixed trim depths, that means measuring each opening. If you want one part number to cover a range, the Delaney solid brass baseboard door stop adjusts from 3-1/2 to 4-1/2 inches, which absorbs the variation without stocking two lengths. Fixed is the cleaner look and has nothing to loosen; adjustable is the fleet-friendly choice.

A baseboard stop like the Deltana BDSR40 screws into the baseboard and takes the door on a rigid brass tip, which keeps the floor clear so nothing trips a vacuum or a cart. A spring stop, such as the Orca Hardware 3-1/8 inch or 3-3/4 inch spring stops, flexes on impact and is more forgiving of a door slammed hard. A floor bumper, like the Delaney 2 inch round solid brass floor bumper, mounts in the floor and is the answer when the door swings past the baseboard entirely or hits a wall with no trim to screw into.

The Emtek 2231 baseboard door stop is the direct counterpart. Both mount to the baseboard rather than the floor, and both are 4 inches long, so the Emtek 2231 lands the door strike at the same height off the floor as the Deltana BDSR40. Pick between them on finish match with the rest of the trim in the room, since the working geometry is the same.

The Delaney 40201X solid brass baseboard door stop adjusts from 3-1/2 inches to 4-1/2 inches, so one part number covers openings where the baseboard reveal is not consistent. The Deltana BDSR40 is a fixed 4 inch length and is the right call when the trim height is known and repeats. For a mixed-vintage building, the adjustable Delaney reduces the number of SKUs you carry on the truck.

Mount to the floor instead. The Delaney 4029XX is a 2 inch height round solid brass floor bumper that sets into the floor and catches the door face. The Deltana BDSR40 is a baseboard bumper and needs trim behind the door to fasten into, so on a tiled or carpeted opening with no base, or where the door swings past the base, the floor bumper is the substitute that actually works.

The Orca Hardware TH-30HD is a heavy duty rigid door stop whose function is door holder, meaning it both stops the door and holds it at that position. The Deltana BDSR40 is a bumper only - it cushions the strike and the door swings back freely. For a corridor, a loading door, or any opening that has to stand open during a move-in, the TH-30HD is the part that does that job.

Both. The BDSR40 half-cylinder tip is shaped so the stop works mounted wide (horizontally along the baseboard) or up-right. That matters when the baseboard is short or when a return wall crowds the swing, since you can turn the bumper to whichever orientation puts the tip where the door lands.

Solid brass, not plated steel or zinc. Both the material and the substrate are brass, so the finish sits on brass rather than on a base metal that rusts through at the contact point once the plating wears. That is also why the unlacquered brass version will patina naturally over time rather than flake.

Six finishes: oil rubbed bronze, polished nickel, brushed nickel, polished chrome, unlacquered brass, and brushed brass. That covers the usual matches for Deltana hinges and levers in the same finish family. Unlacquered brass is the one to pick only if you want it to darken with age, since it has no protective topcoat.

Stop only. The BDSR40 bumps the door and stops it from marking the wall; it will not hold the door in the open position. If you need the door to stay open, that is a holder, and the Orca Hardware TH-30HD is a rigid stop with a holder function.

The Emtek 2231 baseboard door stop is also a 4 inch baseboard stop, so it drops into the same reach from the trim. The visible difference is the tip: the Deltana BDSR40 uses a contemporary half-cylinder tip with a 3/8 inch projection and can be mounted wide or up-right. Pick on which one matches the rest of the trim hardware in the room.

No. The Orca Hardware 3-1/8 inch and 3-3/4 inch spring door stops are base-mounted spring stops that flex when the door hits them, and both carry the door stop function. The Deltana BDSR40 is a rigid solid brass baseboard bumper with a 4 inch body and a half-cylinder tip. They look interchangeable in a parts bin, but the spring stop absorbs the strike by bending while the brass baseboard bumper does not, and the Orca units come in 3-1/8 inch and 3-3/4 inch lengths rather than 4 inches.

Three brass baseboard stops cover most of it. The Deltana BDSR40 is solid brass at a fixed 4 inch length in six finishes including oil rubbed bronze, polished nickel, brushed nickel, polished chrome, unlacquered brass, and brushed brass. The Emtek 2231 is also a 4 inch baseboard door stop. The Delaney 40201X is solid brass and adjusts 3-1/2 to 4-1/2 inches. Standardize on a fixed 4 inch part where the trim package is uniform, and carry the adjustable Delaney for the buildings that are not.

Each. The BDSR40 baseboard bumper is priced and sold per unit, so a job needing a stop on every bedroom door needs one line item per opening, not per pair.
