Deltana WBC238 Convex Flush Bumper 2-3/8" Diameter

The WBC238 is a flush-mounted bumper, meaning it sets into a hole in the wall rather than projecting off the surface on a post. That takes a prepared 2-3/8 inch opening and something to fasten into behind it. On a hollow drywall wall you either hit a stud or use anchors rated for the mounting hardware supplied in the bag. If you cannot cut the wall, a surface-mounted stop is the way to go instead, such as the Ives WS11 heavy duty wall stop with a replaceable rubber bumper, which screws to drywall or masonry.

2-3/8 inches across. That is the full diameter of the brass face, so the wall opening behind it has to be cut smaller than that for the trim ring to cover cleanly. If the hole in your wall is already bigger than 2-3/8 inches, this one will not hide it.

Convex means the face bulges outward, so the door or knob strikes the crown of the bumper. That suits a flat door face or a lever hitting the wall. A concave face is dished inward and is meant to cup a round knob so it seats and does not slide off, like the Delaney 2-1/4 inch concave wall bumper. Match the shape to what is actually hitting the wall: round knob, go concave; flat surface or lever, the convex WBC238 is the one.

Stopping only. The WBC238 cushions the door where it meets the wall and nothing more. If you need the door to stay open, that is a holder, not a bumper. The Ives WS20 manual wall holder with a hinged strike catches and holds the door until released, and the Ives WS40 automatic wall holder does it without the extra step. Those need a strike on the door face; a flush bumper does not.

The Emtek 2255 brass wall bumper with regular rosette is the nearest match in form and material. Both are brass wall bumpers that mount flush to the wall behind the door, and the WBC238 is solid brass in a 2-3/8 inch diameter. The Emtek 2255 uses a regular rosette as its wall plate, so the trim profile differs from the Deltana convex face even though the job at the wall is the same.

A projecting wall stop covers that opening. The Ives WS11 heavy duty wall stop with a replaceable rubber bumper is made for drywall and masonry and stands off the wall to meet the door, and the ABH RM Series wall door stops come in multiple length options so the projection can be matched to the gap. A flush bumper like the Deltana WBC238 sits at the wall surface and only works where the door or its hardware actually contacts that surface.

A wall holder, not a bumper. The Ives WS20 is a manual wall holder with a hinged strike for drywall and masonry applications, and the Ives WS40 is an automatic wall holder with a heavy duty bumper pad that catches the door without anyone bending down. The Deltana WBC238 is a wall bumper only; it absorbs the door and releases it.

They mount the same way but present opposite faces. The Delaney 2-1/4 inch concave wall bumper dishes inward to cup a round knob or rosette, while the WBC238 is a convex bumper 2-3/8 inches in diameter whose face crowns outward to take a flat or lever contact. Confirm which shape the door hardware needs before swapping one for the other, and note the two diameters differ by an eighth of an inch if the existing bumper left a mark on the wall.

Oil Rubbed Bronze is one of the eight finishes the WBC238 comes in. The full run is PVD Polished Brass, Polished Brass, Antique Brass, Oil Rubbed Bronze, Brushed Nickel, Antique Nickel, Polished Chrome and Brushed Chrome. That covers most of the standard residential and light commercial finish families, so a property manager standardizing a building can usually pull one bumper finish across every opening.

Mounting hardware ships in the bag with it. Each bumper is packed individually in a poly bag with its mounting hardware, and it is sold one at a time rather than by the pair or the box, so ordering a count of doors gets you a count of bumpers.

A wall bumper only helps if the knob actually lands on it. When the door swings well past the wall or the knob is missing the mounting point, go to a stop that catches the door earlier: a hinge-side or floor-mounted rigid stop such as the Delaney 3 inch HD rigid door stop, or a spring stop like the Delaney 3 inch spring door stop, which flexes rather than transmitting the hit into the wall. A flush brass bumper like the WBC238 assumes the wall is the right place to take the impact.

Both are brass and both take the door's impact, but they mount differently. The WBC238 sets flush into the wall so nothing projects into the corridor. The Emtek 2255 brass wall bumper mounts on a regular rosette, sitting proud of the wall surface and needing no cut opening. Flush is cleaner and needs wall prep; rosette-mounted is the retrofit-friendly one.

The Delaney 2-1/8 inch hole plate metal cover reads like a small round wall plate and sits in the same size range, but it is a cover for an unused hole and takes no impact from a door. If the job is stopping a door at the wall, a bumper such as the Deltana WBC238 at 2-3/8 inches is the part; the hole plate only conceals an opening left by removed hardware.

A baseboard-mounted stop shifts the work to the floor trim. The Delaney 3 inch HD rigid door stop is a fixed-post stop and the Delaney 3 inch spring door stop flexes on a spring body; both take the door at the baseboard rather than at the wall face where a solid brass bumper such as the Deltana WBC238 goes. The choice comes down to whether the door edge reaches the baseboard on that swing.

For repeated daily impact, the heavy duty wall stops carry a stated duty level: the Ives WS11 and the Ives WS33/WS33X are both heavy duty with replaceable rubber bumpers, so the wear part can be changed without pulling the mounting. The Deltana WBC238 is a solid brass commercial bumper with a one-piece face, which suits openings where the look at the wall matters as much as the impact.

One flush bumper cannot, because it sits at a single depth. The ABH RM Series and ABH RMS Series wall door stops are each offered with multiple length options, so a single series can be run building-wide with the projection varied opening by opening. The Deltana WBC238 is a fixed 2-3/8 inch flush bumper, best used where the door consistently reaches the wall face, and its eight finishes let it match trim across those openings.
