Deltana WB178 Concave Flush Bumper 1-7/8" Diameter

The WB178 is a flush-mounted wall bumper, 1-7/8 inches in diameter, that mounts to the wall surface where the knob or lever lands and absorbs the strike. It has no projecting arm or post, so it only works where the door hardware itself makes contact at the bumper's height. If the door swings past the wall face, or the contact point is the door edge rather than the trim, you want a projecting wall stop instead, like the Ives WS11 heavy duty wall stop with a replaceable rubber bumper.

No. The Deltana WB178 is strictly a bumper: it cushions the door where it meets the wall and stops damage, but it has no catch. For an opening that needs the door to stay open, the Ives WS20 is a manual wall holder with a hinged strike, and the Ives WS40 is an automatic wall holder with a heavy duty bumper pad. Those two engage the door and hold it; the WB178 only absorbs the impact.

The Deltana WB178 is a concave flush-mounted wall bumper 1-7/8 inches in diameter in solid brass. If you want the same concave wall-bumper style in a larger face, the Delaney 2-1/4 inch concave wall bumper covers the same wall-protection job at a 2-1/4 inch diameter, which spreads the contact area and hides a slightly larger scuff mark on the drywall. Both mount flat to the wall and catch the door face rather than projecting on a post.

The Deltana WB178 is a flush concave bumper, meaning it sits nearly flat on the wall and absorbs contact from the door face or from a projecting knob. In a heavy traffic opening where the door swings hard, a heavy duty wall stop like the Ives WS11 or the Ives WS33 is the different approach: both are heavy duty wall stops with a replaceable rubber bumper, so the wear part can be changed out instead of replacing the whole stop, and the WS11 is rated for both drywall and masonry walls. The WB178 is the lower profile choice; the Ives units are the ones built around a serviceable bumper.

A flush wall bumper like the Deltana WB178 only works when the door reaches the wall at the right point. If the door overtravels or the wall is out of reach, a projecting stop is the substitute: the Delaney 3 inch HD rigid door stop and the Delaney 3 inch spring door stop both mount to the baseboard or the door and reach out to catch the swing, and the ABH RM and RMS series wall door stops are offered in multiple length options so you can pick a post long enough to meet the door before it hits trim.

Nine finishes: PVD Polished Brass, Polished Brass, Unlacquered Brass, Antique Brass, Oil Rubbed Bronze, Brushed Nickel, Antique Nickel, Polished Chrome and Brushed Chrome. If you're matching a suite of Deltana levers or hinges across a building, the PVD version of polished brass is the one that resists tarnishing, and unlacquered brass is the one meant to patina over time.

Solid brass through the body, not plated pot metal. That matters in a corridor or an entry that gets daily use, and it's why the unlacquered and antique finishes age rather than flake. Deltana lists it as a commercial-grade item.

Each WB178 ships individually poly bagged with its mounting hardware included. It's sold per piece, so order one per opening. The supplied fasteners suit a normal wall fixing; if you're anchoring into masonry or block, plan on your own anchors for that substrate.

Size and coverage. The WB178 is 1-7/8 inches across; Delaney's concave wall bumper is 2-1/4 inches, so it gives you a bigger contact face and hides more wall damage on a repair. Both are the concave dish style meant to cup a round knob or a lever end. Pick the larger one if you're covering an existing scar, the WB178 if you want a smaller footprint on the wall.

If the existing bumper is a round flush disc of about the same size, the WB178 drops into the same spot, though it's rarely the same hole pattern so expect to patch and re-anchor. Where the old fixing hole is larger than the new bumper's footprint, a hole plate cover such as the Delaney 2-1/8 inch metal cover is the cleaner fix behind or beside the new unit. For matching across a run of doors, order the same finish for every opening, since the nine finishes vary noticeably in tone.

The WB178 is a brass flush bumper, and Deltana classes it as commercial, but it's a decorative-profile part with no replaceable rubber. In a corridor where doors get thrown open hard, a heavy duty unit with a serviceable bumper pad is the longer-lived choice, for example the Ives WS33 or WS11, both of which use a replaceable rubber bumper. Use the WB178 where appearance matters and the impact is moderate, such as offices, hospitality guest rooms and unit entries.

Yes. The Emtek 2255 is a brass wall bumper with a regular rosette, which puts it in the same decorative solid-brass wall-bumper category as the Deltana WB178. The WB178 is a concave flush design 1-7/8 inches in diameter and is offered across nine finishes including polished brass, unlacquered brass, oil rubbed bronze, brushed nickel, antique nickel, polished chrome, brushed chrome, PVD polished brass and antique brass, so the deciding factor between the two is usually which one matches the rosette and finish already on the door.

No, those do two different jobs. The Delaney 2-1/8 inch hole plate metal cover is a blank plate that conceals an existing hole or old stop location in the wall or door. The Deltana WB178 is a functioning concave bumper 1-7/8 inches in diameter that takes the impact of the door. If you are removing an old stop and patching the wall, the hole plate is the right part; if the door still needs something to strike, order the WB178.

The Deltana WB178 is classed for commercial use and is made of solid brass. Among the alternatives, the Sure-Loc wall bumper door stop is described for residential doors, and the Ives WS11 and WS33 are heavy duty wall stops, so the range runs from residential bumper through the brass commercial WB178 up to the heavy duty serviceable Ives units. Match the choice to how hard and how often the door is being swung.

The Deltana WB178 is a one-piece solid brass concave flush bumper supplied in an individual poly bag with mounting hardware, so service means swapping the unit. If a replaceable wear part matters for your maintenance program, the Ives WS11 and the Ives WS33 are heavy duty wall stops built with a replaceable rubber bumper, and the Ives WS40 wall holder uses a heavy duty bumper pad. Facilities standardizing on a stop they can rebuild in place usually go that direction; a brass decorative opening usually stays with the WB178.

Emtek's 2255 brass wall bumper with a regular rosette is the closest peer in the same material and mounting style. Deltana's WB178 is the concave dish profile, 1-7/8 inches across, and both are surface-mounted bumpers rather than projecting stops, so the decision comes down to rosette style and which finish family matches the rest of your trim.
