Deltana WB250 Wall Mount Concave Flush Bumper, 2-1/2" Diameter

The WB250 is a flush bumper, 2-1/2 inches in diameter, that mounts flat to the wall and takes the hit from the door face. It only works where the door itself reaches the wall. If the part striking your wall is a lever, a thumbturn, or a pull that stands proud of the door face, a flush bumper never gets touched and you want a projecting wall stop instead, like the Ives WS11 heavy duty wall stop or an ABH RM Series stop, which comes in multiple lengths so you can match the standoff to how far the lever sticks out.

It comes down to where the door lands. A wall bumper works when the door swings back and contacts a wall within its arc, and it keeps the floor clear of a trip hazard, which matters in corridors and healthcare or hospitality spaces. If the door opens into open floor with no wall behind it, or the wall behind it is glass, a mirror, or a chase you cannot anchor into, you need a floor stop instead, such as the Delaney 3 inch HD rigid door stop or the Delaney 3 inch spring door stop. The spring type flexes rather than stopping the door dead, which is easier on the hinges but lets the door travel further.

No - it is a bumper, not a holder. The WB250 stops the door against the wall and lets it swing back. If the opening needs the door to stay put, the Ives WS20 is a manual wall holder with a hinged strike, which the installer engages by hand, and the Ives WS40 is an automatic wall holder with a heavy duty bumper pad that catches the door as it swings. Both are wall mounted like the WB250, so the substitution is a matter of what the door has to do at the end of its swing, not of where the hardware goes. Note that the WS40 is a light duty unit, so match it to traffic accordingly.

The Delaney 2-1/4" Concave Wall Bumper covers the same job in a smaller footprint. Both are concave wall bumpers that mount to the wall and take the door's impact on a dished face, so the door edge or knob seats into the cup rather than striking flat. The Deltana WB250 is 2-1/2 inches in diameter; the Delaney unit is 2-1/4 inches, which is the one to specify when a narrow return, a chair rail, or an adjacent trim piece leaves you short of the full 2-1/2 inch circle.

For a high-traffic commercial opening on drywall, the Ives WS11 is the heavy duty answer. It is a heavy duty wall stop with a replaceable rubber bumper rated for drywall and masonry, so the rubber face is a wear item you swap instead of replacing the whole assembly, and the mounting is intended for hollow-wall anchoring. The Deltana WB250 is a wall-mounted flush concave bumper in steel, 2-1/2 inches in diameter, and it sits nearly flat against the wall - the right look for a finished corridor or a unit interior, but the WS11 or the similar Ives WS33 is what you specify when the door is being thrown open dozens of times a day and the bumper face will need renewing.

Go to a projecting wall stop. The ABH RM Series and ABH RMS Series wall door stops are offered in multiple length options, so you pick the projection that closes the gap between the finished wall and the door's arc. The Deltana WB250 is a flush bumper - the door has to reach the wall for it to do anything, and its 2-1/2 inch concave face gives no standoff. Measure from the wall to the door's stopping point first; if that distance is more than the door hardware itself projects, an RM or RMS length is the correct specification.

Mounting hardware ships in the bag. Each WB250 is packed individually in a poly bag with the mounting hardware included, sold one per unit. What is not included is the wall anchor for your substrate, so on hollow drywall between studs you will want a toggle or a suitable anchor rated for the impact of a door being thrown open.

Commercial. The WB250 is a steel-bodied flush bumper, steel both in material and substrate, so it is not a plated zinc or plastic-cored residential bumper. For high-abuse commercial openings where the rubber gets chewed up, a stop with a replaceable bumper such as the Ives WS33/WS33X or WS11 lets you swap the pad without pulling the base off the wall.

Eight finishes on the WB250: PVD Polished Brass, Polished Brass, Antique Brass, Oil Rubbed Bronze, Brushed Nickel, Antique Nickel, Polished Chrome, and Brushed Stainless. That is the full range, so a property manager standardizing across a floor can pull the same bumper for brass, bronze, nickel and chrome openings. The PVD Polished Brass is the one to specify if the bumper sits in an exterior or high-humidity spot where a lacquered brass would go patchy.

The WB250 measures 2-1/2 inches across, so it is a quarter inch wider overall than a 2-1/4 inch bumper such as the Delaney 2-1/4 inch concave wall bumper, and it mounts through the wall the same way. That extra diameter covers the old shadow ring on the paint on most swaps. It fastens through a single center point, so if the existing anchor hole is off from where the WB250 lands, you are patching one hole either way.

Steel, in both the material and substrate spec, with the brass and bronze looks applied as finishes rather than being solid brass through the body. If your spec calls for solid brass on the stop to match a brass package, the Emtek 2255 is a brass wall bumper with a regular rosette. For a steel body the WB250 is the right call on cost and impact resistance, and the PVD Polished Brass finish is the more durable of the two brass options.

They are the same class of part - a flush wall bumper mounted on the wall behind the door. The difference is the material and the trim treatment. The Deltana WB250 is steel and comes in eight finishes including PVD Polished Brass, Oil Rubbed Bronze, Brushed Nickel, Antique Nickel, Polished Chrome, Polished Brass, Antique Brass and Brushed Stainless. The Emtek 2255 is a brass wall bumper supplied with a regular rosette, so the visible ring is Emtek's rosette profile rather than the flush concave face of the WB250. If you are matching an opening already trimmed in Emtek rosettes, the 2255 keeps the visual set; if you want the flush concave disc, the WB250 is the one.

Yes, if the swing allows it and you would rather not put an anchor in the wall. The Delaney 3" HD Rigid Door Stop and the Delaney 3" Spring Door Stop both stop the door away from the wall entirely - the rigid version takes the hit on a solid post, the spring version absorbs it in a coiled body. The Deltana WB250 is wall mounted, so it needs sound backing behind the drywall and it leaves the floor clear. The trade is a fixed obstruction in the walking path versus a fastener in the wall; in corridors and unit entries where a floor stop is a trip point, the wall-mounted WB250 is usually preferred.

Only if you are putting a working bumper back in the same spot. The WB250 is a functional steel bumper 2-1/2 inches in diameter, not a blank. If the opening is being abandoned and you just need the wall made good, the Delaney 2-1/8" Hole Plate Metal Cover is the plate for that - it conceals the opening without adding a stop. Property managers turning units often need both: the cover where a stop was removed, the WB250 where a new one goes in.

Concave describes the face: it dishes inward rather than standing out as a dome, so the door face seats into the cup instead of striking a single high point. That spreads the load across the 2-1/2 inch diameter and is why a flush bumper sits so close to the wall. It is the right profile for a flat door face contacting flat; if what hits your wall is a raised panel edge or projecting trim, the contact lands on the rim rather than in the dish and a projecting stop serves better.

One per unit. The WB250 is sold each, packed individually in its own poly bag with hardware, so there is no carton minimum forcing you into a box of ten for a single opening. That suits both a one-door repair and a floor-by-floor rollout where you are counting exact quantities.
