Rockwood 404 Concave Solid Cast Wall Stop, 1" Projection, 2-7/16" Diameter, Plastic Anchor Fastener

The 404 ships with a #8 x 1 inch round head wood screw and a plastic anchor, so it mounts into hollow drywall using the anchor. If you're hitting solid backing (a stud or blocking behind the board), the wood screw goes straight in and you skip the anchor. For masonry or concrete block you'd need a different fastener than what comes in the box.

One inch of projection. That's the gap between the wall face and the door face when the door is stopped, so it will clear a lever handle only if the lever's own projection is under an inch. Longer levers, thick trim, or a door that swings hard into a corner usually want a longer wall stop or a floor stop instead.

It carries ANSI A156.16, type L02251, and it is a commercial-grade item. That's the standard architectural hardware spec a facility or institutional spec writer looks for on auxiliary hardware, so the L02251 designation is what you cite on a submittal.

A wall stop only works where the door actually reaches a wall within its projection, 1 inch on the 404. If the door swings into open space, past the wall's edge, or into furniture, a wall stop won't reach and you want a floor stop or a spring/rigid base stop instead, such as the Delaney 3 inch rigid door stop or the Delaney 3 inch spring door stop. If you need the door to stay open rather than just stop, that's a holder, not a stop, and the Ives WS20 manual wall holder or WS40 automatic wall holder does that job.

For the same concave cast wall bumper look, the Emtek 2255 brass wall bumper with regular rosette and the Delaney 2-1/4 inch concave wall bumper are the nearest equivalents. If you want a replaceable rubber bumper so you can service the stop without pulling it off the wall, the Ives WS11 and WS33 heavy duty wall stops are built that way. The ABH RM and RMS series are the option when you need a choice of stop lengths rather than a fixed projection.

A wall stop and a wall holder are different jobs. The Rockwood 404 is a solid cast wall stop with a concave rubber bumper - it arrests the door at 1 inch of projection from the wall and lets it swing back. To hold the door open, the Ives WS20/WS20X is a manual wall holder with a hinged strike for drywall and masonry applications, and the Ives WS40 is an automatic wall holder with a heavy duty bumper pad. The manual holder requires someone to engage the strike; the automatic engages when the door reaches it. Holders need a corresponding strike or catch plate on the door, so budget for the door-side hardware that a plain stop like the 404 does not use.

Probably not. The Rockwood 404 mounts to the wall and ships with a #8 x 1 inch round head wood screw and plastic anchor, which puts the load into drywall unless you can hit blocking. Where the wall cannot take the impact, move the stop to the door or the floor instead. The Delaney 4021XX is a 3 inch heavy duty rigid door stop and the Delaney 40210X is a 3 inch spring door stop, both of which mount to the door itself and bear against the wall over a wider footprint. The spring version flexes on contact; the rigid version does not. Either removes the point load that a wall-mounted stop concentrates on unbacked drywall.

Concave. The rubber face is dished, so it cups the strike point on the door rather than pressing on a single flat spot. Concave stops are the usual choice where the door hits a lever or knob, since the dish captures the knob face; a convex or flat bumper is what you want when the door hits flush and you just need a pad. The Delaney 2-1/4 inch concave wall bumper is the same concave style from another brand.

Cast brass body with a rubber bumper, not a stamped or die cast shell. Solid cast is what takes repeated impact in schools, hospitals, hotels, and detention work, which is the traffic Rockwood builds this line for. The bumper is the wear item; the cast body is what keeps the stop on the wall.

Yes, and that's the usual way it gets bought. Specify one model and one finish code across the openings, so 404 626 for satin chrome throughout, and the ANSI A156.16 L02251 designation is what carries onto the hardware schedule. The only opening-by-opening check is whether 1 inch of projection clears the lever at each door; anywhere it doesn't, that opening needs a longer stop or a floor stop rather than a different finish.

They are both brass wall bumpers, but they are pitched at different openings. The Emtek 2255 is a brass wall bumper with a regular rosette, a decorative-rosette treatment aimed at finish-driven residential and boutique work. The Rockwood 404 is a solid cast commercial wall stop certified to ANSI A156.16 under function L02251, which is what an institutional or MRO spec typically calls out by number. On a corridor where the door hardware schedule references an ANSI/BHMA function, the 404 answers that line item directly. On a guest room or an executive suite where the rosette needs to match the rest of the trim, the 2255 is the aesthetic choice.

The Ives WS11/WS11X is described for both drywall and masonry, and the Ives WS20/WS20X wall holder covers drywall and masonry applications as well, so a mixed-substrate building can carry one part number across both wall types with the appropriate anchor. The Rockwood 404 comes with a #8 x 1 inch round head wood screw and plastic anchor, which is the drywall pack; masonry locations need the corresponding anchor for the substrate. If the goal is a single line item on the purchase order for every opening in the facility regardless of wall construction, the Ives heavy-duty stops are specified that way from the start.

The Rockwood 404 is a solid cast commercial wall stop certified to ANSI A156.16, function L02251. Among the alternatives, the Ives WS11/WS11X, WS20/WS20X, and WS33/WS33X are each designated heavy duty, while the Ives WS40 automatic wall holder is designated light duty. Duty level tracks traffic: a stairwell or a loading corridor that sees a door thrown open hundreds of times a day is where the heavy-duty designation earns itself, and where a replaceable bumper keeps the maintenance simple. An office suite door or a unit interior does not put that cycle count on the stop.

The Rockwood 404 is offered in 604 satin brass, 613 dark satin bronze, 619 satin nickel, 625 bright chrome, and 626 satin chrome - the standard architectural finish numbers that let a stop match levers, hinges, and pulls already scheduled on the opening. The Emtek 2255 is a brass wall bumper with a regular rosette, which is the alternative when the visual treatment matters more than matching a BHMA finish code. For a property manager replacing stops piecemeal across a building, matching the existing BHMA number is usually faster than matching by eye.
