Rockwood 449 Door Stop Riser, Mill Aluminum

The 449 is a carpet riser, not a stop by itself. It is a full size aluminum base that raises a No. 440 or No. 442 dome stop up off the floor so the dome clears carpet and pile and still catches the door. On bare concrete, tile, or wood you generally don't need it; on carpeted corridors and guest rooms it's what keeps the dome stop working at the right height.

Yes - the Rockwood 449 is a riser base for a dome stop, so the finished assembly stops the door and nothing more. For hold-open, the Ives FS40 / FS41 / FS42 / FS43 automatic floor stop and holder and the SOSS MDH magnetic door holder and stop at 3-5/16 inch by 1-3/4 inch both hold the leaf open, and both are heavy duty. The Orca Hardware 22HD Series goose neck unit is also listed as a door holder and covers door thicknesses of 1-3/8 inch or 1-3/4 inch.

The 449 is a riser only - a full size carpet riser that provides a sturdy base for mounting the No. 440 or No. 442 dome stop, so the bumper still has to be ordered separately. If you want a floor stop that arrives as a complete assembly with the bumper already on it, a dome stop such as the Ives FS13 heavy-duty brass floor dome stop with replaceable rubber bumper or the Ives FS17 heavy-duty brass floor dome stop with rubber bumper is a single-piece purchase. The 449 approach is chosen when you need the dome lifted above carpet pile rather than set directly on the finished floor.

A riser like the Rockwood 449 raises a dome stop so it clears carpet pile, but a taller stop body does the same job in one piece. The Orca Hardware 23LP Series dome floor stop is a low rise dome with a gray tip, so it sits closer to the floor and is the opposite choice. For real clearance, a gooseneck reaches up from the floor to meet the door face - the Orca Hardware 22HD Series goose neck floor stop with black tip, the Emtek 2253 goose style door stop, and the Delaney gooseneck floor door stop are all that style. Note the Orca 22HD is a door holder, so it will hold the door open as well as stop it.

It ships with a #12 wood screw and a plastic anchor. That covers a wood subfloor directly and a drilled hole in concrete or masonry with the anchor set in it. If you are fastening into a hollow or unusual substrate, plan on supplying your own anchor to suit.

Stop only. The 449 is a riser for a dome stop, and a dome stop limits door swing without holding it. If you need hold-open, look at a stop and holder such as the Ives FS40 / FS41 / FS42 / FS43 automatic floor stop and holder, or a magnetic unit like the SOSS MDH magnetic door holder and stop.

The Rockwood 449 riser measures 1-7/8 inch diameter, so it keeps a small footprint on the floor. Comparable small-diameter floor bumpers include the Deltana UFBP4505 round universal floor door bumper with pattern cap at 1-5/8 inch, the Deltana UFB4505 round universal floor door bumper at 1-1/2 inch, and the Emtek 2257 cylindrical floor bumper at 1-1/2 inch, all in that same range. If a wider base is wanted, the Deltana UFBD3505 round universal floor bumper is 3-1/2 inch and decorative.

The 449 is an aluminum riser intended for commercial openings, and it raises a dome stop off carpet rather than adding security. Where tampering or prying is the concern, the Ives FS18S/FS18L security floor stop is built for that duty and is heavy duty. The Ives FS13 and FS17 brass floor dome stops are also heavy duty, with the FS13 offering a replaceable rubber bumper so the wear item can be changed without pulling the stop.

The Rockwood 449 is a commercial carpet riser that has to be paired with a 440 or 442 dome stop. On light residential work, a one-piece floor stop is less to specify: the Sure-Loc cylindrical floor stop is made for residential doors, the Sure-Loc floor stop with spring covers modern door stop designs, and the Delaney dome door stop and Emtek 2251 half dome door stop are plain dome units that fasten straight to the floor.

No. The 449 is a round 1-7/8 inch diameter riser fastened with a #12 wood screw and plastic anchor, and its bore is sized for the 440 or 442 dome stop rather than for another maker's bumper. A square unit such as the Deltana UFBS138 square universal floor door bumper at 1-3/8 inch is a different footprint and mounts on its own pattern, as does the Emtek 2254 floor door bumper at 1-3/8 inch by 1-1/4 inch. Treat any of those as a full replacement of the riser and stop together, not a cap swap.

Two: mill aluminum and brass. Pick the one that matches the dome stop sitting on top of it, since the riser is visible at the floor line.

It's a commercial-grade item, used in the same settings as the rest of the Rockwood line: institutional buildings, offices, retail, schools, detention, sports facilities, hotels and restaurants, and higher-end residential work.
