Deltana WB238/C Wall Mounted Concave Flush Bumper 2-3/8" Diameter, Solid Brass (Clearance)

That depends on how far your lever or knob projects. The WB238/C is a flush bumper: a 2-3/8 inch diameter solid brass disc with a concave face that mounts flat to the wall, so it sits nearly against the surface and takes the impact of the door face or knob rather than standing off from the wall. If your lever throws several inches off the door, you need a projecting wall stop with a post instead, like the Ives WS11 heavy duty wall stop or an ABH RM Series stop that comes in multiple lengths.

Deltana rates the WB238/C for commercial use, and the 2-3/8 inch brass face spreads the strike over a wider area than a small rubber tip does. The limit is the wall, not the bumper: a flush disc puts the load straight into the substrate, so on drywall it needs to land on solid blocking or a proper anchor. For high traffic openings where the door gets thrown, an Ives WS33 or WS11 heavy duty wall stop with a replaceable rubber bumper is the tougher answer, since the wear part can be swapped without pulling the stop.

No. The WB238/C is a wall-mounted bumper that stops the door and lets it swing back. A holder keeps the door open until it is released: the Ives WS20 is a manual wall holder with a hinged strike for drywall and masonry, and the Ives WS40 is an automatic wall holder with a heavy duty bumper pad. Both the WS20 and WS40 require a matching strike or catch on the door, which a bumper does not. If the requirement on the drawing is hold-open, a bumper will not satisfy it regardless of diameter.

The Delaney 2-1/4 inch Concave Wall Bumper is the nearest match in form. Both are concave wall bumpers meant to catch the knob or lever face against a wall, and the Delaney measures 2-1/4 inches across where the Deltana WB238/C is a 2-3/8 inch diameter solid brass bumper. If the trim already on the door sits close to the wall and a slightly smaller footprint suits the paint line or a narrow stretch of wall between openings, the Delaney covers the same job in a tighter disc.

Use a projecting wall stop rather than a flush bumper. The Ives WS11 is a heavy duty wall stop with a replaceable rubber bumper rated for drywall and masonry, and the ABH RM Series and RMS Series wall door stops are offered in multiple length options so the stop can reach out to the door face where the wall sits back. The Deltana WB238/C is a flush bumper, which assumes the knob or lever strikes the wall plane directly; when there is a gap to span, the length options on the ABH series are what solve it.

Oil Rubbed Bronze is the only finish offered on the WB238/C. It is solid brass underneath, so if you are matching hinges and lever trim across a run of openings, match to the ORB finish and not to a plated steel stop.

Mounting point is the whole difference. The WB238/C mounts to the wall and the door comes to it. A Delaney 3 inch spring door stop or 3 inch HD rigid door stop mounts to the baseboard or the door itself and catches the door low. Use a wall bumper when the door swings into a wall you want to protect and the baseboard route is blocked by carpet, tile, or a walking path; use a base stop when there is no wall behind the door at the right height.

The Delaney 2-1/4 inch concave wall bumper is the smaller equivalent, an eighth of an inch down in diameter from the Deltana WB238/C's 2-3/8 inches, which can be the difference on a narrow return or a tight casing reveal. If you want to stay in brass, the Emtek 2255 brass wall bumper with a regular rosette is the other brass option.

The Emtek 2255 Brass Wall Bumper with Regular Rosette is the other brass flush-mount bumper in the same family of parts. It shares the wall-mounted brass construction of the Deltana WB238/C, which is a 2-3/8 inch solid brass bumper, and adds a regular rosette to the bumper face. For a property manager matching decorative brass trim across a run of doors, the choice usually comes down to which rosette profile lines up with the escutcheons and roses already hung.

Move the stop to the door or the floor. The Delaney 3 inch HD Rigid Door Stop and the Delaney 3 inch Spring Door Stop both mount away from the wall plane and absorb the swing at the base of the door, which is what a wall-mounted bumper like the Deltana WB238/C cannot do when the swing ends over a doorway, a stair opening, or glass. The rigid version holds firm; the spring version flexes on contact.

No, those are different parts. The Delaney 2-1/8 inch Hole Plate Metal Cover is a blank cover for an unused hole; it takes no impact. The Deltana WB238/C is a 2-3/8 inch wall-mounted flush bumper, sized to receive the knob or lever strike. If a previous stop left a hole that the new 2-3/8 inch bumper does not fully cover, the hole plate is a patch, not a stop, and a bumper still has to be set where the door actually lands.

Partly, and only if the damage is small. The WB238/C is a 2-3/8 inch solid brass disc that mounts flush to the wall, so it will conceal a hole well inside that footprint, but it is a bumper and it needs sound material behind it to anchor into. If the hole is the problem and not the door, the Delaney 2-1/8 inch hole plate metal cover is the part made for that job.

The WB238/C mounts to the wall face, so the substrate decides the fastener, not the bumper. Brass flush bumpers ship with fasteners for typical wall material, and masonry needs the appropriate anchor set for concrete or block. If you are specifying across a building with mixed drywall and masonry, the Ives WS11 and WS33 wall stops are catalogued for both drywall and masonry, which keeps one part number across the whole job.
