Rockwood 490 Door Holder with Stop

Projection is 2-1/8 inches from the wall on the holder body, and the door-mounted strike projects 2 inches off the door face. Those two numbers are what decide whether the door swings far enough to meet the unit. Measure from the finished wall surface to the point on the door that will contact it: if your base trim, chair rail, or a wainscot cap sits proud of the wall in that spot, the holder body has to land above or below it, since the 490 mounts to the wall rather than to the floor.

Two direct alternatives in the same wall-mounted holder-with-stop family: the Ives WS20, a manual wall holder with a hinged strike rated heavy duty, and the Ives WS40, an automatic wall holder with a heavy duty bumper pad, which is a light duty unit. The difference between manual and automatic is how the door gets released. On a manual holder someone has to flip or lift the strike to engage or free the door; an automatic holder catches on its own when the door swings into it. The 490 is the cast brass version of the same idea.

No. The 490 is a wall-mounted unit with a 2-1/8 inch projection, so the door has to swing to within roughly that distance of the wall for the strike to reach it. If the door stops short, in the middle of a corridor or against nothing, you need a stop that spans the gap or one that mounts elsewhere. The ABH RM and RMS Series wall door stops are offered in multiple length options for exactly that condition, where the wall is farther back than a standard stop can bridge.

The 490 is a holder with stop, so it includes a strike that catches and holds the door open. If hold-open is not wanted, a plain wall stop does the job with one piece and no door-mounted strike. The Ives WS11 is a heavy duty wall stop with a replaceable rubber bumper prepped for drywall and masonry, and the Ives WS33 is a heavy-duty wall door stop that also takes a replaceable rubber bumper. Delaney's 2-1/4 inch concave wall bumper is another bumper-only wall stop. Any of these mounts on the wall alone and leaves the door face untouched.

They hold a door open by different methods and are not interchangeable. The Rockwood 490 is manual: the cast brass holder body engages a strike mounted on the door, with a holder projection of 2-1/8 inches against a strike projection of 2 inches. The Ives WS40 is an automatic wall holder with a heavy duty bumper pad and is rated light duty. On a high-traffic institutional opening, the light duty rating on the WS40 is the deciding fact; for a door that should only hold when someone deliberately sets it, the 490's manual strike is the behavior being asked for.

The 490 mounts on the wall with a 2-1/8 inch holder projection, so it only works where the door face reaches the wall within that projection plus the 2 inch strike. Where the gap is larger, a longer wall stop closes the distance: the ABH RM Series and ABH RMS Series wall door stops are offered in multiple length options, so the projection can be selected to suit the wall. Those are stops rather than holders, so they arrest the door without holding it open.

Among wall-mounted options, the Ives WS11, the Ives WS20, and the Ives WS33 all carry a heavy duty rating, while the Ives WS40 automatic wall holder is light duty. Of the heavy duty three, the WS20 is the one with a hold-open function, using a hinged strike on the door, which is the same arrangement as the Rockwood 490 with its door-mounted 2 inch strike. The WS11 and WS33 stop the door only, both with replaceable rubber bumpers, which matters on a corridor where the bumper is the wear item.

Cast brass and built for commercial openings. Rockwood classifies the 490 as a commercial product and the body is cast brass rather than stamped or plated pot metal, which is why these show up in institutional buildings, offices, retail, schools, detention, sports facilities, and hotels. For a light residential interior door a simple spring or rigid stop is more than enough, but on a corridor door that gets kicked open all day, a cast brass holder with a stop is the right class of part.

Satin chrome, US26D (the 626 finish designation), and that is the only finish offered on the 490. US26D is the standard satin chrome used across most commercial lever, closer, and hinge lines, so it matches a building already standardized on satin chrome trim. If your openings are done in satin stainless (US32D), the two read close but not identical side by side on the same door.

The 490 holder base is 2-3/4 by 2-1/2 inches and lands on the wall, so the anchoring is whatever your wall requires: a hollow-wall anchor or blocking behind drywall, a masonry anchor in block or brick. On drywall without blocking, a wall holder takes real leverage when someone yanks a held-open door, and that pull is what strips a light anchor. If you want a unit expressly catalogued for both substrates, the Ives WS20 manual wall holder is listed for drywall and masonry applications.

Both are ABH wall door stops offered in multiple length options, the RM in the RM Series and the RMS in the RMS Series, so either can be specified to a projection that suits the wall-to-door distance. Both differ from the Rockwood 490 in the same way: the 490 is a holder with stop, pairing a cast brass wall-mounted body with a door-mounted strike, while the ABH stops arrest the door without a hold-open strike. For a distributor pulling an exact identity, the 490 is Rockwood model 490 in cast brass.

They solve different parts of the problem. The Delaney 3 inch HD rigid door stop and the Delaney 3 inch spring door stop are base-mounted stops that absorb the door at the end of its swing; neither holds the door open. The Rockwood 490 is a commercial holder with stop in cast brass, with a 2-3/4 inch by 2-1/2 inch holder base and a door-mounted strike, so it both stops and holds. Where the requirement is only to protect the wall from the lever, the Delaney rigid or spring stop covers it with a single fastener point; where the door must stay parked open, the 490's strike is required.

The Ives WS11 and the Ives WS33 are both specified with replaceable rubber bumpers, so the wear item comes off without disturbing the wall anchors - useful on a fleet of doors where the bumpers get replaced on a cycle. The Rockwood 490 is a different device: a cast brass holder with stop where a door-mounted strike engages the wall-mounted holder to keep the door open, rather than a bumper pad taking the impact.

Not with the 490 itself, which is a stop and holder rather than a cover plate. When a previous stop leaves a hole in the door or wall that the new 2-3/4 by 2-1/2 inch holder base won't cover, the Delaney 2-1/8 inch hole plate metal cover is made to cap it. Check the old hole against the 490's base footprint first, since the base often hides a smaller previous fastener pattern outright.

When the new hardware does not land on the old fastener pattern, a hole plate covers the opening. The Delaney 2-1/8 inch hole plate metal cover is a plate for exactly that, and 2-1/8 inches is a common leftover bore. It is not a stop or a holder in itself, so it goes in alongside whichever device is being installed rather than in place of it.
