Delaney 2-1/4" Concave Wall Bumper

Projection is 7/8 inch, so the door face stops just under an inch from the wall. That is enough to keep a lever or a knob rose off the drywall on most residential and light commercial openings, but it will not clear a deep lever throw or a thick pull. Measure from the wall to the outermost point of your trim when the door swings open, and if that number is more than 7/8 inch you want a longer wall stop instead, like the ABH RM or RMS Series, which are sold with multiple length options.

Wall bumpers of this style anchor into the wall behind the finish, so on hollow drywall you need a toggle or a solid anchor hitting blocking or a stud, and on block or brick you need a masonry anchor. Delaney's 2-1/4 inch bumper is a zinc-substrate stop with a 2-1/4 inch base, so plan the anchor for the wall type you actually have. If you want a stop the manufacturer explicitly rates for both wall types, the Ives WS11 and WS33 are heavy duty wall stops listed for drywall and masonry.

The Delaney 2-1/4 inch concave wall bumper is a zinc wall stop with a 2-1/4 inch base diameter and 7/8 inch projection. Where a corridor door gets constant use and you want a bumper you can service rather than replace, the Ives WS11 is a heavy duty wall stop with a replaceable rubber bumper, rated for drywall and masonry. The Ives WS33/WS33X is also a heavy-duty wall door stop with a replaceable rubber bumper. Both let a maintenance tech swap the rubber without pulling the base off the wall.

The Delaney 2-1/4 inch concave wall bumper projects 7/8 inch off the wall, so it only works when the door leaf actually reaches the wall surface. When the baseboard, a chair rail, or a recessed wall puts the strike point further out, move to a stop built in multiple lengths: the ABH RM Series wall door stops and the ABH RMS Series wall door stops are both offered with multiple length options, so you pick the projection that meets the door where it lands.

The base is 2-1/4 inches in diameter, which is what sits flat against the wall surface. If you are replacing an older stop and the previous fastener left a torn patch of drywall, anything within roughly a 2-1/4 inch circle disappears under the base. Wider damage than that shows around the edge and wants a patch before mounting.

Concave means the face is dished, so it catches a door knob or a lever rose and cups it. That is the shape you want when the trim on the door is what makes contact. A convex or flat-face bumper is the one to use when the door face itself hits the stop and there is no knob at that height. Delaney's 2-1/4 inch bumper is the concave version.

Three finishes: 626 satin chrome, 619 satin nickel, and 613 satin bronze oil-rubbed. Those are standard BHMA finish codes, so if the levers already on your doors are specified 626 or 619 or 613, the bumper matches by code rather than by eye. That is the practical way to spec these across a building without holding samples up to the door.

Swing the door fully open and mark where the knob or lever rose lands on the wall, then set the center of the bumper on that mark. With only 7/8 inch of projection you have very little margin, so the height matters more than it does with a long stop: if the bumper sits above or below the rose, the door trim hits bare wall instead of the dished face. On a flush door with no protruding trim at that point, mount it where the door face lands and use the same measurement.

The mounting hole rarely lines up between brands, so treat it as a new install rather than a drop-on swap. What works in your favor is the 2-1/4 inch base, which is large enough to hide the old anchor hole in most cases. If you specifically want brass rather than zinc, the Emtek 2255 is a brass wall bumper with a regular rosette.
