Rockwood 402 Convex Solid Cast Wall Stop, 1" Projection, 2-7/16" Diameter, Lead Anchor Fastener

The Rockwood 402 has a 1 inch projection, so the door face stops about an inch clear of the wall. That is enough to protect the wall from a lever handle only if the lever plus escutcheon sits within that inch; longer lever trim or a thumbturn that projects further needs a deeper stop or a floor stop instead.

The 402 ships with a #8-32 x 1 inch truss head machine screw and an anchor. That anchor set is intended for a solid substrate (masonry, block, or a wood blocking/stud behind the board). Into bare hollow drywall with no backing, swap to a hollow wall anchor rated for the impact load, or hit a stud. The mounting is concealed, so the screw does not show once the cast body is set.

It is listed to ANSI A156.16 under function number L02101, which is the wall stop designation in that standard. It is a commercial-grade item, the kind specified on institutional, office, retail, education, hotel and detention work.

The Rockwood 402 has a 1 inch projection, so it only works where the wall sits close behind the door swing. Where the gap is larger, a longer-rod wall stop is the usual answer: the ABH RM Series and ABH RMS Series wall door stops are offered with multiple length options so you can pick a rod that reaches the door. If the door needs to be held open rather than just stopped, the Ives WS20 is a manual wall holder with a hinged strike for drywall and masonry, and the Ives WS40 is an automatic wall holder with a bumper pad.

The Ives WS33/WS33X is the nearest heavy-duty counterpart. Like the Rockwood 402, it is a wall-mounted door stop with a rubber bumper, and Ives rates it heavy duty. The Rockwood 402 is a solid cast convex stop with a 1 inch projection meeting ANSI A156.16, L02101. The Ives WS11/WS11X is also a heavy duty wall stop with a replaceable rubber bumper for drywall and masonry, which is the option to look at if you want the bumper serviceable rather than replacing the whole stop.

Convex, like the Rockwood 402, means the rubber bumper crowns outward, so it takes the door on a rounded face. That works when the door hits the stop squarely or slightly off-center. A concave bumper cups inward and is meant to catch a projecting knob or lever inside the dish. If a round knob is what is striking the wall, a concave unit such as the Delaney 2-1/4 inch concave wall bumper is the right shape; if it is the door face or edge, the convex 402 is.

The 402 is a solid cast brass unit with a rubber bumper and a 1 inch projection, sized for a compact footprint. If your priority is field-replaceable rubber on a heavy-use opening, the Ives WS11 and the Ives WS33 are both heavy duty wall stops listed with a replaceable rubber bumper. Pick the 402 where you want the cast brass body and concealed fastening to match other Rockwood trim.

Usually yes, since the 402 mounts on a single #8-32 x 1 inch screw into an anchor and the cast body covers the area around it. If the old anchor blew out the drywall and the crater is wider than the stop base, patch and re-anchor into solid backing first, or cover the damage with a plate such as the Delaney 2-1/8 inch hole plate metal cover before resetting.

Yes. The Rockwood 402 is a commercial solid cast stop built to ANSI A156.16, L02101. For apartment interiors and homes, the Sure-Loc DS-W1 is a wall bumper door stop for residential doors, the Delaney 40270x is a 2-1/4 inch concave wall bumper, and the Emtek 2255 is a brass wall bumper with a regular rosette. Those are the ones to use where traffic is light and the decorative match to residential trim matters more than a commercial grade.

Not in the same position. The Rockwood 402 is a wall-mounted stop that fastens into the wall with a #8-32 x 1 inch machine screw and anchor. The Delaney 40210X 3 inch spring door stop and the Delaney 4021XX 3 inch HD rigid door stop are base-mounted stops that go into the floor or the door bottom rail, so they stop the door at the leading edge rather than at the wall. Choose the wall stop when the wall is behind the swing and the floor cannot be drilled.

Satin chrome, 626, which is the standard commercial finish and the usual match for satin chrome or brushed stainless lever trim and hinges already in the building. The body is cast brass with a rubber bumper, so the plating sits on solid brass rather than a stamped shell.

It will work anywhere, but it is a commercial-grade cast brass stop and it is priced and built for institutional openings. For plain residential doors a lighter wall bumper like the Sure-Loc wall bumper door stop, or a baseboard-mounted spring or rigid stop such as the Delaney 3 inch spring or 3 inch heavy duty rigid stop, covers the same job.

They are the same solid cast wall stop family, all cast brass with a rubber bumper and concealed mounting. The model 402 is the convex version specified here. If a drawing calls for 400 or 401, check the projection called out on the schedule before substituting, since that is what separates them.
