Rockwood 401 Convex Solid Cast Wall Stop, 1" Projection, 2-7/16" Diameter, Plastic Anchor Fastener

The 401 ships with a #8 x 1 inch round head wood screw and a plastic anchor, so it mounts into hollow drywall without a stud behind it. If you can catch blocking or a stud, use the wood screw directly into it, that is the stronger hold in a high-traffic corridor. For masonry or CMU walls you will want a stop supplied for that condition, like the Ives WS11, which is listed for drywall and masonry both.

Yes. The 401 carries ANSI A156.16 with the type designation L02101, and it is a commercial-grade item rather than a residential bumper. That designation is what a spec writer or facilities buyer needs when the drawing calls out a wall stop by ANSI type rather than by brand.

A wall stop like the Rockwood 401 only stops the door, it does not hold it. The convex rubber bumper absorbs the swing and protects the wall, then the door is free to close. If you need the door to stay open, you want a holder instead: the Ives WS20 is a manual wall holder with a hinged strike, and the Ives WS40 is an automatic wall holder. Those need a strike plate on the door, so check the door face has room for it.

The Ives WS33 is the nearest peer - a heavy-duty wall door stop with a replaceable rubber bumper. The Rockwood 401 uses a convex bumper with concealed mounting and carries ANSI A156.16, L02101. The difference that matters on a repair order is the bumper: the WS33 bumper is replaceable, so a worn pad can be swapped without pulling the base off the wall, while the 401 is a solid cast body with the bumper fitted to it. The Ives WS11 is the other heavy-duty option in the same role, also with a replaceable rubber bumper and rated for drywall and masonry.

Go to a series built around length rather than a fixed projection. The ABH RM Series wall door stops and the ABH RMS Series wall door stops are both offered with multiple length options, so the stop can be specified long enough to reach past a baseboard or a wainscot and contact the door face square. The Rockwood 401 is a fixed 1 inch projection, which puts it in the flush-wall application where the door leaf meets the wall surface directly.

No - the 401 is a stop only. For hold-open, the Ives WS20 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 WS20 requires someone to engage the holder at the door; the WS40 catches on its own when the door swings to the wall. Both mount in the same wall location a 401 would occupy.

The 401 needs a wall to land on - it ships with #8 x 1 inch round head wood screws and a plastic anchor, which is a wall-substrate fastening. Where there is no backing in the swing path, move to a floor or door-mounted stop: the Delaney 3 inch HD rigid door stop and the Delaney 3 inch spring door stop both take the load at the base rather than the wall. The rigid version holds a fixed position; the spring version flexes as the door contacts it.

No. The 400 series solid cast stops use concealed mounting, so the fastener is hidden behind the bumper and you see a clean cast face. That matters in lobbies, hotel corridors and anywhere the hardware is at eye level.

Use a wall stop when the door swings against a wall within reach of the door edge, which is the normal condition in a corridor. A wall-mounted stop like the 401 keeps the floor clear, so nothing to trip over and nothing for a mop or cart to catch. Go to a floor stop when the door swings into open space with no wall behind it, or when the wall is glass or the far side is a shared partition you cannot anchor into. Delaney offers both a 3 inch spring door stop and a 3 inch heavy duty rigid stop for those floor and base applications.

Weigh the duty rating first. The Rockwood 401 is a commercial part carrying ANSI A156.16, L02101. The Sure-Loc wall bumper door stop is built for residential doors, and the Delaney 2-1/4 inch concave wall bumper and Emtek 2255 brass wall bumper with regular rosette are bumpers in the same family. Those suit a dwelling-unit door; for corridor and classroom traffic the commercial-rated 401 or a heavy-duty peer such as the Ives WS11 is the matched choice.

The shape of the contact face. The Rockwood 401 carries a convex bumper, so the rubber crowns outward and the door face lands on the high point of the dome. The Delaney 2-1/4 inch concave wall bumper is dished the other way, cupping toward the door. Concave faces are commonly paired with a door-mounted projecting element that seats into the cup; a convex bumper takes a flat door face. Confirm which the opening already has before swapping one for the other.

Two: 619 satin nickel and 626 satin chrome. Both are standard architectural finishes, and 626 is the one that matches most commercial lever and closer hardware already hanging in an office or school. If you are standardizing a building, 626 is usually the safer match to existing trim.

Fasteners are included: a #8 x 1 inch round head wood screw and a plastic anchor per stop. Nothing else to order for a standard drywall install. If you are fitting these out across a floor of units, that is one line item per opening, no separate fastener pack.

The Rockwood 401 is offered in 619 satin nickel and 626 satin chrome, both standard architectural finishes. For a brass-bodied look in the same bumper role, the Emtek 2255 is a brass wall bumper with a regular rosette. Where the standard needs to extend to hold-open openings in the same program, the Ives WS20 manual wall holder and Ives WS40 automatic wall holder cover those positions while the 401 handles the stop-only doors.
