Deltana WBC250 Wall Mount Convex Flush Bumper, 2-1/2" Diameter

The WBC250 is a flush-mounted convex bumper, 2-1/2 inches in diameter, that takes the hit from the door face where it swings into the wall. It sits nearly flat against the wall with a slight dome, so it stops the door itself, not a protruding lever. If the lever is what is punching your drywall, you want a projecting wall stop with a shaft, like the Ives WS11 heavy duty wall stop, which stands off the wall far enough to catch the door before the handle lands.

Mounting hardware ships with it. Each WBC250 is packed in an individual poly bag with the mounting hardware included, and it is sold one per unit, so ordering a count of ten gets you ten bumpers with ten sets of fasteners. What is not included is any drywall anchor rated for your substrate; a flush bumper takes a direct door strike, so if you are landing it on hollow drywall rather than a stud or solid masonry, plan on a toggle or anchor.

Stop only. The WBC250 is a bumper, it absorbs the door's impact and the door swings back freely. Nothing about it catches or retains the door. If you need the door to stay open, that is a holder, not a bumper: the Ives WS20 manual wall holder uses a hinged strike you engage by hand, and the Ives WS40 automatic wall holder catches the door on contact. Buyers replacing a broken hold-open with a flush bumper are the most common wrong order on this kind of part.

The Deltana WBC250 is a wall mount convex flush bumper at 2-1/2 inch diameter, made of steel and offered in eight finishes including polished chrome, oil rubbed bronze and brushed stainless. The nearest peer in the same flush wall-bumper form is the Emtek 2255 brass wall bumper with regular rosette, which is brass rather than steel. The Delaney 2-1/4 inch concave wall bumper is the other close match in form, in a concave face rather than convex and a 2-1/4 inch diameter. Convex bumpers stand slightly proud of the wall to meet the door face; concave ones cup around a door-mounted knob or projection, so the door hardware you are protecting against decides which of the two suits the opening.

A flush bumper such as the Deltana WBC250 sits nearly flat against the wall, so the door has to reach the wall for it to work. When there is a gap, a projecting stop covers it: the ABH RM Series and ABH RMS Series wall door stops are both offered in multiple length options, so the projection can be picked to meet the door where it actually stops. If the wall is not usable at all, the Delaney 3 inch HD rigid door stop and the Delaney 3 inch spring door stop mount to the door or base instead.

No. The Deltana WBC250 is a bumper: it stops the door and protects the wall, and the door swings back freely. To hold a door open you need a wall holder. The Ives WS20 is a manual wall holder with a hinged strike for drywall and masonry applications, where someone drops the strike to catch the door, and the Ives WS40 is an automatic wall holder with a heavy duty bumper pad that catches the door as it swings. Bumper and holder are frequently confused when reordering, so confirm which function the opening actually needs before you standardize a building on one.

Eight finishes: PVD Polished Brass, Polished Brass, Antique Brass, Oil Rubbed Bronze, Brushed Nickel, Antique Nickel, Polished Chrome, and Brushed Stainless. The PVD Polished Brass is worth singling out if the bumper is going somewhere humid or hard-cleaned, since PVD is a deposited coating rather than a lacquer. For a property manager matching a building standard, the spread here covers most common lever and hinge finishes, so the stops can follow whatever is already on the doors.

Commercial. The WBC250 is a steel bumper classed for commercial duty, which is what makes it a candidate for corridors, offices, and multi-family common areas rather than just a bedroom door. Steel through the body means it takes repeated impact better than a plastic or plated zinc bumper. For an opening with real abuse, a door that swings hard on a closer in a school or hospital corridor, a heavy duty stop such as the Ives WS33 with a replaceable rubber bumper is the step up, because the wear part can be swapped rather than the whole stop.

A convex bumper like the WBC250 domes outward, so the door face meets the high point at the center and the contact is a small area that stands slightly proud of the wall. A concave bumper dishes inward and is generally paired with a projecting element, a knob or a rounded stop tip, that seats into the cup. If your door hardware presents a rounded knob to the wall, look at a concave design such as the Delaney 2-1/4 inch concave wall bumper. For a flat door face, convex is the one you want.

Sometimes, and it depends on where the door actually lands. A flush bumper mounts on the wall at the height the door face strikes, so it needs an unobstructed wall surface at that point. A floor or base-mounted spring stop, like the Delaney 3 inch spring door stop, mounts to the baseboard and flexes; a rigid version such as the Delaney 3 inch HD rigid door stop does not. If the door swings into a window, a chair rail, or open air past the end of the wall, the wall bumper has nothing to land on and you need the base-mounted type.

No. The WBC250 is a fixed flush bumper at a single 2-1/2 inch diameter with essentially no standoff, so it only works where the door face reaches the wall itself. Doors that stop short, or that need the stop to reach out past a baseboard or a piece of trim, need a stop offered in varying lengths, the ABH RM Series and RMS Series wall door stops both come with multiple length options for that situation.

It is not. The Delaney 2-1/8 inch hole plate metal cover is a cover plate for an existing hole in a wall or door; it takes no impact. The Deltana WBC250 is a steel wall bumper that absorbs the door striking the wall. The two are often bought together after a knob has punched through drywall: the plate closes the damage, the bumper stops it happening again.

The Deltana WBC250 is rated for commercial use and is a flush steel bumper 2-1/2 inches in diameter, with the finish range carrying the decorative side. The Ives WS11 and WS33/WS33X are both heavy duty wall stops with replaceable rubber bumpers, and the WS40 automatic wall holder is a light duty unit. Specify by traffic and by whether the bumper needs to be a serviceable wear part on that opening; specify by finish where the corridor hardware is being matched.

The WBC250's 2-1/2 inch diameter covers a fair amount of wall, so it will conceal a small anchor hole under its footprint, but only if you can mount the new bumper on the same centerline. Line up the door's strike point first and the coverage second. If the hole is the problem rather than the stop, a dedicated cover plate does the job cleanly, the Delaney 2-1/8 inch hole plate metal cover is made for exactly that.

Steel is the substrate, with the finish applied over it. That matters if you are matching solid brass trim on an interior job, since a solid brass bumper will age differently over years than a plated steel one; the Emtek 2255 brass wall bumper is the solid brass alternative if that consistency matters to you. For durability against door impact, the steel body is the harder part.

Swing the door slowly to the wall and mark where the door face makes contact, that mark is the center of the WBC250. Because the bumper is flush and only 2-1/2 inches across, there is little margin for a bad center; a stop mounted too high or too low lets a corner of the door hit bare drywall. Standard practice is to land it behind a solid point on the door, near the lock stile at mid-height, and to hit a stud or use an anchor rated for repeated impact.
