Rockwood 463 Heavy Duty Door Stop

The 463 is a grout-set stop, not a screw-and-anchor stop. Installation calls for drilling a 1 inch diameter hole 2-1/2 inches deep and filling it with anchoring grout to set the stop. That means you need a concrete or masonry floor with at least 2-1/2 inches of usable depth, plus grout on the truck. On a wood floor, a raised slab with radiant tubing, or over a post-tension slab you cannot core, this is the wrong stop and you want a surface-mounted floor stop that fastens with an anchor instead, such as the Ives FS13 or the Orca 23LP dome stop.

Height is 1-3/4 inches with a 2 inch diameter. Measure the undercut on your door before ordering: the door has to clear 1-3/4 inches of stop, so an opening with a large floor-to-door gap, heavy carpet, or a mat well is where this one works. If your leaf sits close to the finish floor, a low rise dome such as the Orca 23LP is the better shape.

No. The 463 is a stop only, it arrests the door swing and nothing more. If you need the leaf to stay open, you want a holder: the Ives FS40 / FS41 / FS42 / FS43 automatic floor stop and holder, the SOSS MDH magnetic door holder and stop, or a gooseneck style holder like the Orca 22HD or the Delaney gooseneck.

Only if the existing stops are grout set. The 463 needs a 1 inch by 2-1/2 inch deep cored hole filled with grout, so it will not reuse the fastener holes from a surface-mounted stop, and the 1-3/4 inch height may differ from what came out. Where you are matching existing surface-mounted domes, an Ives FS13 or FS17 heavy duty brass dome stop is the closer replacement. Where the old stops keep loosening under traffic, moving the whole building to the grouted 463 is the reason people specify it.

The Ives FS13 is the nearest match. Like the Rockwood 463, it is a heavy duty floor dome stop with a replaceable rubber bumper, so the wear part can be swapped without pulling the base out of the slab. The Rockwood 463 stands 1-3/4 inches high with a 2 inch diameter and its bumper is retained by a security Torx machine screw. The Ives FS17 is the same heavy duty brass floor dome stop family but with a rubber bumper that is not called out as replaceable, which matters on a high traffic opening where the bumper is the consumable.

The Rockwood 463 mounts by drilling a 1 inch diameter by 2-1/2 inch deep hole and filling it with anchoring grout, which is a poured floor job. Where coring is not an option, the Deltana UFB4505 universal floor door bumper is a 1-1/2 inch round solid brass unit, and the Deltana UFBS138 is the same universal floor bumper idea in a 1-3/8 inch square. The Emtek 2254 floor door bumper at 1-3/8 by 1-1/4 inches and the Emtek 2257 cylindrical floor bumper at 1-1/2 inches are surface floor bumpers as well. These are low profile bumpers rather than a grouted heavy duty stop, so match the choice to how hard the door swings.

The Rockwood 463 is a floor stop only. For an opening that has to hold, the Ives FS40 / FS41 / FS42 / FS43 is a heavy duty automatic floor stop and holder with adjustable door to floor clearance, so one part both stops and holds. The SOSS MDH is a heavy duty magnetic door holder and stop measuring 3-5/16 by 1-3/4 inches. The Orca Hardware 22HD Series goose neck floor stop is catalogued with a door holder function and fits 1-3/8 inch or 1-3/4 inch doors.

The Rockwood 463 is a floor mounted dome type stop 1-3/4 inches high with a 2 inch diameter, so it catches the bottom edge of a door hung close to the floor. When the gap under the door is too large for a low stop to reach the door face, a gooseneck riser is the usual answer: the Delaney Gooseneck Floor Door Stop, the Emtek 2253 goose style door stop, and the Orca Hardware 22HD Series goose neck floor stop with black tip, which is listed for 1-3/8 inch or 1-3/4 inch doors. At the other end, the Orca 23LP Series is a low rise dome floor stop with a gray tip for openings that need minimal height.

Yes, and that is the point of the design. The bumper is replaceable and is held by a security Torx machine screw, so you swap the rubber instead of coring out the grouted base and redoing the floor. Budget a security Torx bit for your maintenance kit, since a standard Torx driver will not engage the pin-in-center head.

The security Torx screw on the bumper is the tamper feature, and the grout-set base means there are no exposed anchors to back out. Rockwood specifies these for institutional buildings including educational and detention work. If you need a stop rated for that duty with a surface-mount base instead, the Ives FS18S/FS18L security floor stop is the comparable in that category.

One finish, 630 satin stainless steel (US32D). That matches satin stainless lever trim, push plates, and hinges on a typical commercial opening, so it drops into a 630 hardware schedule without a special order. There is no brass or bronze option on the 463; for a solid brass floor bumper in a decorative finish look at the Deltana UFB or UFBD series.

Three things beyond the stop: a 1 inch masonry bit that will drill 2-1/2 inches deep, anchoring grout, and a security Torx bit if you ever plan to change the bumper. No anchors, screws, or mounting plate are involved, the grout is the fastening. Plan the install around cure time for the grout, since the stop cannot take a door strike until it sets.

The Rockwood 463 uses a security Torx machine screw to retain a flame resistant high impact bumper, and it is grouted into a 1 inch by 2-1/2 inch deep hole in the slab rather than surface anchored, which removes the exposed anchors that get attacked first. The Ives FS18S / FS18L is the purpose built alternative, a heavy duty security floor stop offered in two lengths. Both are commercial grade parts; the 463 is specified commercial and is used on institutional, detention, educational and hospitality work.

Commercial. Rockwood specifies the 463 for institutional buildings, offices, retail, educational, detention, sports facilities, hotel and restaurant work, and higher end residences. The grouted base and the replaceable bumper are what make it survive high traffic openings where a screwed-down residential bumper works loose. For a house or light residential job, a surface bumper like the Emtek 2254 or Deltana UFBS138 is the more usual choice.

The bumper material is a flame resistant high impact compound, which is why Rockwood puts this stop in institutional corridors. Note that the stop itself is floor mounted hardware and does nothing to the door assembly, so it does not affect the door's own rating either way.

The Rockwood 463 comes in 630 satin stainless steel, which is the common institutional standard alongside brushed stainless pulls and push plates. Among the peer floor stops, the Deltana UFB4505, UFBD3505, UFBP4505 and UFBS138 universal floor bumpers are solid brass, so a brass base metal is being finished rather than stainless. For facilities standardizing on stainless heavy duty stops, the Ives FS13 and FS17 heavy duty floor dome stops are the closer functional peers to spec against.
