Rockwood 400 Convex Solid Cast Wall Stop, 1" Projection, 2-7/16" Diameter, Plastic Toggle Fastener

The 400 ships with a plastic toggle and a #6 x 1-1/2 inch flat head sheet metal screw, so it anchors into hollow drywall without blocking behind it. If you are fastening into solid masonry or into wood blocking, the toggle is not used and you will want the appropriate anchor for that substrate instead.

One inch of projection. That is the gap between the finished wall and the face of the door when the lever or knob contacts the bumper, so measure your trim or handle projection first. If your lockset sticks out further than an inch, the knob will hit the wall before the stop does and you need a longer stop such as the Rockwood 401 or 402.

It is a commercial-grade stop, certified to ANSI A156.16 and carrying the type number L02101. That is the number a spec writer or facility buyer puts on the hardware schedule, and it is the same standard that covers architectural door trim across institutional work.

The 400 is a bumper stop only - it cushions the door at the end of its swing and does not hold it. For hold-open, the Ives WS20 manual wall holder uses a hinged strike you engage by hand and mounts to drywall or masonry, and the Ives WS40 automatic wall holder catches the door on its own and includes a heavy duty bumper pad. WS20 is rated heavy duty and WS40 is rated light duty, so match the choice to the weight and traffic of the leaf.

The Ives WS11 heavy duty wall stop is the nearest peer. Both are wall-mounted bumper stops for commercial openings, and the WS11 is rated heavy duty with a replaceable rubber bumper and mounting for drywall or masonry. The Rockwood 400 is a solid cast convex wall stop with a 1 inch projection, concealed mounting, and a #6 x 1-1/2 inch FH SMS with plastic toggle for hollow wall anchoring. If the bumper on a high-traffic door gets chewed up and you want to swap just the bumper rather than the stop, the replaceable-bumper WS11 is the one to look at; if you want a cast one-piece convex profile, stay with the 400.

When the knob does not reach the wall, or the wall behind is glass or millwork, go to a floor or baseboard stop instead. The Delaney 3 inch HD rigid door stop and the Delaney 3 inch spring door stop are both base-mounted rather than wall-mounted; the rigid version is a fixed post and the spring version flexes on contact. The Rockwood 400 is a wall stop with a 1 inch projection, which only works where the door swings into reachable wall.

Five: 606 satin brass, 613 oil rubbed bronze, 619 satin nickel, 626 satin chrome, and BSP black suede powder coat. The 626 and 619 are the usual picks for matching commercial lever trim across a building; BSP is the one to use when the rest of the openings are black.

Convex. The rubber crowns outward, which suits doors with a knob or a lever rose that makes contact on a flat face. A concave bumper cups a round knob instead, so if you are stopping a ball knob and want it captured, the Delaney 2-1/4 inch concave wall bumper is the shape for that.

Cast brass body with a rubber bumper, and the mounting is concealed so there are no exposed screws in the face. Solid cast brass is what gets specified for schools, hotels, and healthcare corridors rather than stamped or plated pot metal. For openings that see very heavy abuse and where you want a field-replaceable bumper, the Ives WS11 and WS33 are heavy duty wall stops with replaceable rubber.

A wall stop only works where the door actually reaches a wall within an inch of the handle. If it does not, go to a floor or hinge-mounted stop. The Delaney 3 inch rigid door stop and the 3 inch spring door stop are both base-mount options for that situation.

No, and it is worth being clear on the difference. The Delaney 2-1/8 inch hole plate metal cover is a trim plate that conceals an existing hole in a wall or door - it takes no impact. The Rockwood 400 is a solid cast wall stop with a rubber bumper that absorbs the door strike. If a previous stop pulled out of the drywall you may want both: the 400 relocated onto solid backing, and a plate over the old damage.

It comes down to what part of the door hits it. The Rockwood 400 has a convex bumper face, which suits contact from a lever or knob end that needs a domed surface to strike. The Delaney 2-1/4 inch wall bumper is concave, a dished face that cups a round knob and helps keep it centered. Check what is on the door before you order, because the wrong profile lets the knob skid off the bumper and into the drywall.

The Emtek 2255 brass wall bumper with regular rosette is the decorative counterpart - a brass bumper carried on a rosette, aimed at finished residential trim. The Rockwood 400 is a solid cast convex stop with concealed mounting, offered in Black Suede Powder Coat, 613 Oil Rubbed Bronze, 619 Satin Nickel, 626 Satin Chrome, and 606 Satin Brass, so if you are matching architectural finish numbers across a building the 400 gives you the standard codes to specify against.

Nothing stops you using it residentially, and solid cast brass is common in higher-end homes. It is classed as commercial hardware though, so it is heavier and pricier than a residential bumper. The Sure-Loc DS-W1 wall bumper and the Emtek 2255 brass wall bumper with regular rosette are the residential-scale options.
