Deltana WB238U10B – Frequently Asked Questions
1) Will the Deltana WB238 wall bumper stop a lever handle from hitting the wall, or does it only work for the door edge?
The WB238 is a flush wall bumper with a concave face, 2-3/8 inches in diameter. The concave dish is meant to catch a round knob or the end of a lever, not the flat door edge. Mount it so the knob strikes the center of the dish. If the door swings hard into the wall well below or above the knob line, a projecting wall stop that reaches out from the wall is the better call, like the Ives WS11 heavy duty wall stop or the ABH RM Series, which come in multiple lengths to bridge that gap.
2) Is a flush wall bumper like the Deltana WB238 rated for commercial traffic, or should I use a heavy duty wall stop?
Deltana rates the WB238 for commercial use, and a solid brass flush bumper handles normal office, hospitality and multi-family door traffic. Where it is the wrong choice is a high-abuse opening: a stairwell, a loading area, or any door with a closer that throws it hard. There the load is better carried by a heavy duty stop with a replaceable rubber bumper, such as the Ives WS11 or WS33, where the wear part can be swapped instead of replacing the whole assembly.
3) I need a wall bumper that also holds the door open. Does the Deltana WB238 do that?
No. The WB238 is a bumper only, it stops the door and lets it swing back. If you need the door to stay open, you want a wall holder instead: the Ives WS20 is a manual wall holder with a hinged strike, and the Ives WS40 is an automatic wall holder with a bumper pad. Note the WS40 is rated light duty, so for a heavy or closer-equipped door the WS20 is the sturdier pick.
4) What is the closest equivalent to the Deltana WB238 concave wall bumper from another brand?
The Emtek 2255 brass wall bumper with regular rosette is the nearest match in kind: like the WB238, it is a brass wall-mounted bumper rather than a projecting rod-and-base stop. The WB238 is a concave flush bumper 2-3/8 inches in diameter in solid brass, offered in PVD Polished Brass, Polished Brass, Antique Brass, Oil Rubbed Bronze, Brushed Nickel, Antique Nickel, Polished Chrome, and Brushed Chrome. Both sit flat against the wall, so either one suits a finished corridor where a protruding stop would be a snag hazard.
5) The door swings far enough to hit the wall hard - what should I use instead of a flush wall bumper?
For openings where the door arrives with real force, a heavy duty projecting wall stop absorbs the swing better than a flush pad. The Ives WS11 is a heavy duty wall stop with a replaceable rubber bumper for drywall and masonry, and the Ives WS33/WS33X is a heavy-duty wall door stop with a replaceable rubber bumper. Both stand off the wall to catch the door edge or lever, where the Deltana WB238 is a flush concave bumper the door face meets at the wall.
6) The wall behind the door is not solid where the bumper would land - what are my options?
A flush bumper like the Deltana WB238 puts its fastener wherever the door face happens to strike, which may fall between studs. The ABH RM Series and ABH RMS Series wall door stops both come in multiple length options, so you can pick a projection that reaches from a sound anchor point to the door. Where the wall cannot be used at all, the Delaney 3 inch HD rigid door stop and the Delaney 3 inch spring door stop mount to the floor or the door instead.
7) Does the Deltana WB238 bumper come with mounting screws or do I need to buy fasteners separately?
Mounting hardware is in the bag. Each WB238 ships individually poly bagged with its mounting hardware included, sold one per unit. What is not included is an anchor for hollow drywall. The supplied hardware suits a solid backing, so if you are landing it on drywall between studs, add a toggle or a hollow wall anchor to the order.
8) What finishes does the Deltana WB238 wall bumper come in for matching existing door hardware?
Eight finishes across brass, nickel and chrome: PVD Polished Brass, Polished Brass, Antique Brass, Oil Rubbed Bronze, Brushed Nickel, Antique Nickel, Polished Chrome and Brushed Chrome. The PVD polished brass is the one to specify if the bumper sits in a corridor or entry that gets cleaned often, since PVD holds its color where lacquered brass eventually wears. For a building standard, pick the finish that matches your lever and hinge finish and order the same WB238 for every opening.
9) What is the difference between a flush wall bumper and a spring or rigid floor-style door stop?
They solve the problem at different ends of the swing. A flush bumper like the WB238 mounts on the wall and takes the impact where the knob lands, so nothing sits on the floor to trip over or catch a mop. A base-mounted stop screws to the door or baseboard and stops the door earlier in its arc, which is what you want when the wall behind is glass, tile or a fixture you cannot drill. Deltana's flush bumper is a wall-mount part; if the wall is not an option, look at a base or spring stop such as the Delaney 3 inch spring door stop or the Delaney 3 inch HD rigid door stop.
10) Is there a smaller concave wall bumper than the 2-3/8 inch Deltana WB238 if my wall space is tight?
The WB238 face measures 2-3/8 inches across, which needs a clear flat area of at least that much where the knob strikes. In a tight spot, such as against a door casing or a corner return, the Delaney 2-1/4 inch concave wall bumper is a slightly smaller face of the same style. The Emtek 2255 brass wall bumper with regular rosette is another brass option if you want a rosette look to match a rosette-style lockset.
11) Which wall stop can be rebuilt in place instead of replaced when the rubber wears?
The Ives WS11 and the Ives WS33/WS33X both carry a replaceable rubber bumper, so an MRO crew standardizing across a building can restock the rubber rather than the whole stop. The Deltana WB238 is a solid brass concave flush bumper supplied as a complete unit in an individual poly bag with mounting hardware.
12) Can a 2-1/8 inch hole plate cover be used in place of a wall bumper?
No. The Delaney 2-1/8 inch hole plate metal cover is a blank plate for concealing an opening in a surface - it takes no impact. The Deltana WB238 is a solid brass concave bumper 2-3/8 inches in diameter, made to receive the door and suppress the impact against the wall. The two look similar as round wall discs, which is why they get confused; only the WB238 stops a door.
13) Which wall stop should I standardize on across a commercial building?
It depends on what the openings need. The Deltana WB238 is a commercial-rated solid brass concave flush bumper in eight finishes including Polished Chrome, Brushed Nickel, and Oil Rubbed Bronze, which lets one part match varied trim throughout a property. Where you want one heavy duty catalog number across all doors instead, the Ives WS11, WS20, and WS33/WS33X are all heavy duty and all rated for both drywall and masonry, so a single line item covers stud walls and CMU corridors alike.
14) Is the Ives WS40 a heavy duty substitute for a brass wall bumper?
The Ives WS40 is an automatic wall holder with a heavy duty bumper pad, but the unit itself is light duty. It is built to catch and hold the door open automatically rather than to take repeated hard impact. For a corridor where the door swings hard, the Ives WS11 or WS33/WS33X are heavy duty; for a flush brass face at the wall, the Deltana WB238 is the concave bumper.
15) Is the Deltana WB238 solid brass or brass plated steel?
Solid brass, not a plated shell. That matters on a bumper because the fixing screw pulls through the body every time the door hits it, and a thin plated part deforms at the screw hole. Solid brass also means the finish is on a stable substrate rather than over steel that can rust if the wall gets wet.
16) Can I use the Deltana WB238 to replace a wall bumper that left a hole in the drywall?
Often yes, and that is a common reason to size up. At 2-3/8 inches across, the WB238 covers a larger footprint than most small builder-grade bumpers, so relocating slightly and letting the new escutcheon cover the old damage frequently works. Where the old fastener hole is too large to catch new hardware, a hole plate cover such as the Delaney 2-1/8 inch hole plate metal cover conceals the opening, and you mount the new bumper into sound backing nearby.
17) How do I figure out where to mount the Deltana WB238 on the wall?
Open the door slowly to where you want it to stop and mark where the knob or lever end touches the wall. That mark is the center of the 2-3/8 inch bumper. Check the mark for a stud or solid blocking before drilling, since the included hardware is intended for solid backing. Keep the bumper far enough off the baseboard that the full dish sits on flat wall, otherwise the door edge, not the knob, ends up taking the hit.
