Deltana WB100 Convex Flush Bumper 1" Diameter

The WB100 is a flush-mounted convex bumper, 1 inch in diameter, so it sits nearly against the wall and only absorbs the impact of whatever part of the door reaches it first. That works when the knob, lever, or edge of the door is what strikes the wall. If the door swings hard enough that trim, a thumbturn, or a projecting lever would clear the bumper and still hit plaster, you want a projecting wall stop instead: the Ives WS11 heavy duty wall stop or the Ives WS33/WS33X, both with replaceable rubber bumpers, stand off the wall on a post. The ABH RM and RMS Series wall stops are sold in multiple length options for exactly that reason.

They solve the impact at different heights. A flush bumper like the WB100 mounts on the wall at the point the door face or hardware strikes, which is usually the right call when the door has a lever or knob that reaches the wall first, or when the wall has no baseboard to land on. A floor or base-mounted stop catches the bottom of the door instead and keeps the hardware off the wall entirely, which is the better choice on doors with a closer, on heavy solid-core doors, or where you do not want a fixing in a finished wall. Delaney's 3 inch rigid door stop and 3 inch spring door stop are that style. If you need the door to stay open rather than just stop, that is a holder, not a bumper: the Ives WS20 manual wall holder with hinged strike or the WS40 automatic wall holder.

The Emtek 2255 brass wall bumper with regular rosette is the nearest brass-bodied alternative. The WB100 is a solid brass convex flush bumper at 1 inch diameter, so it sits nearly flat against the wall with a small contact face. The Emtek 2255 uses a separate rosette behind the bumper, which spreads the mounting across a wider trim ring. Both are brass wall-mounted bumpers rather than floor stops, so either works on the same wall behind a door swing.

They are not the same face profile and they meet the door differently. The Deltana WB100 is a convex bumper, so the contact face bulges outward and takes the strike at its center point. The Delaney 2-1/4 inch concave wall bumper is dished inward, which is the profile intended to cradle a projecting knob or lever end rather than take a flat door face. Check what part of the door actually reaches the wall: a flat door edge or a door with no protruding trim suits the convex WB100, while a door whose knob is what contacts the wall is the case a concave bumper is shaped for. The Delaney is also 2-1/4 inch across against the WB100 at 1 inch, so the two leave different size marks on the wall and different hole patterns.

No. The Deltana WB100 is a bumper, so it stops the door at the wall and lets it swing back. To hold the door open you need a wall holder: the Ives WS20 is a manual wall holder with a hinged strike for drywall and masonry, meaning someone drops the strike to catch and release the door, and the Ives WS40 is an automatic wall holder with a heavy duty bumper pad, which catches the door on contact. If you want both functions on the same opening, the holder replaces the bumper rather than sitting alongside it, since both occupy the same point on the wall behind the door.

Move to a base-mounted or hinge-side stop instead of a wall bumper. The Deltana WB100 is a wall-mounted flush bumper and only works where the door face or trim actually reaches the wall. If the door swings past the wall or into open floor, the Delaney 3 inch HD rigid door stop and the Delaney 3 inch spring door stop both mount to the baseboard or floor and intercept the door away from the wall. The rigid version is a solid post, the spring version flexes on contact; pick by whether you want the door to stop dead or give slightly.

Solid brass, and Deltana classifies the WB100 as commercial. Brass is why it takes a real plated finish and why the exposed face does not chalk or yellow the way a plated zinc bumper does. Two things to be honest about for high-traffic openings: it is a 1 inch flush bumper, so the contact area is small, and the striking face is brass rather than a replaceable rubber pad. In a corridor that sees carts and constant swing, a heavy duty stop with a replaceable bumper (Ives WS11 or WS33) is the longer-service choice. For apartment interiors, offices, and hotel guest rooms, the WB100 is doing the job it was built for.

Each WB100 ships in its own poly bag with mounting hardware included, sold one per unit. What is not included is drywall anchoring. A flush wall bumper wants a solid backing, so if the strike point lands in hollow drywall between studs you will need to add a toggle or a suitable anchor. The Ives WS11 and WS33 stops are supplied for both drywall and masonry conditions if you would rather have that handled in the box.

Nine finishes: PVD Polished Brass, Polished Brass, Unlacquered Brass, Antique Brass, Oil Rubbed Bronze, Brushed Nickel, Antique Nickel, Polished Chrome, and Brushed Chrome. That covers the full Deltana finish range for this bumper, so a property manager standardizing a building can pick one and repeat it. Two worth understanding before you commit a fleet order: PVD Polished Brass is a physical vapor deposition coating that resists tarnish, while Unlacquered Brass is bare brass with no protective coat, so it will patina over time by design. If you want every bumper in the building to look the same in three years, do not mix those two.

Convex means the striking face bows outward, so the door meets a small raised dome and the contact point is the center of the bumper. A concave bumper is dished inward and is shaped to receive a rounded knob, cradling it rather than being struck flat. Pick convex when a lever, a door edge, or the door face is what hits the wall. Pick concave when a round knob is the striking part and you want it to seat rather than glance off, which is what Delaney's 2-1/4 inch concave wall bumper is for. The WB100 is the convex type at 1 inch diameter, a noticeably smaller footprint than that 2-1/4 inch concave plate.

No. The WB100 is a wall-mounted stop, mounted through the wall surface with the supplied hardware so the door strikes it. It is not a door-mounted or frame-mounted part, and it has no glass or mullion attachment. For a glass front or an aluminum storefront opening where you cannot fix into the adjacent wall, you want an overhead stop or a floor-mounted stop, not a flush wall bumper.

One inch is a small, deliberately discreet target. It works when you know exactly where the door strikes and the strike point does not move, which is the normal case for a knob or lever on a door with consistent swing. It is less forgiving if the door sags, the hinges wear, or the strike point drifts, because the door can miss a 1 inch dome and hit the wall beside it. Where you want more margin, a larger plate such as the Delaney 2-1/4 inch concave wall bumper gives more than twice the diameter to catch, and the Ives WS11 or WS33 projecting stops take the door before it gets near the wall at all.

Emtek's 2255 brass wall bumper with regular rosette is the closest cross-brand match we carry: same decorative brass wall bumper category, mounted on a rosette rather than sitting flush. The practical difference is profile. The WB100 is a flush 1 inch convex bumper that reads as a small disc on the wall, while a rosette-mounted bumper carries a trim ring around it and is usually specified to match a rosette-style lever or a matching escutcheon set. If your levers already have rosettes and you want the bumper to echo them, that is the reason to go Emtek. If you want the bumper to disappear, stay flush.

The ABH RM Series wall door stops and the ABH RMS Series wall door stops are both offered with multiple length options, so one series covers openings where the door lands at different distances from the wall. The Deltana WB100 is a single 1 inch diameter flush bumper, so it standardizes on finish across a fleet rather than on projection - it comes in nine finishes including polished chrome, brushed nickel, oil rubbed bronze and antique brass. Which way you standardize depends on whether your openings vary in geometry or in trim appearance.

No, those solve opposite problems. The Delaney 2-1/8 inch hole plate metal cover is a blank plate for concealing an existing opening in a door or wall, with no bumper function at all. The Deltana WB100 is a solid brass convex bumper that takes the impact of the door. If a previous stop tore out and left damage, the plate covers the hole but nothing then stops the door - you still need the bumper, or a projecting stop, mounted where the door lands.

Individually. Each WB100 is bagged on its own with its mounting hardware, and the unit of measure is each, so 40 doors means 40 units. Ordering a single finish across the whole job also keeps the look consistent, since all nine Deltana finishes are available on the same 1 inch bumper.

Not reliably. At 1 inch diameter the WB100 covers very little wall around its own fixing, so an existing hole from a larger stop or an anchor will likely still show. Two ways to handle it: patch and repaint before mounting, or cover the old opening with a plate such as the Delaney 2-1/8 inch hole plate metal cover and site the new bumper where the door actually strikes. A larger-diameter bumper like the Delaney 2-1/4 inch concave wall bumper will also hide more of an old fixing if the new location has to be the same spot.
