Rockwood 466 Heavy Duty Door Stop

The 466 sets into the floor rather than screwing down to it. You drill a 1 inch diameter hole 2-1/2 inches deep and fill it with anchoring grout, then set the stop. There are no exposed fasteners once it cures, which is why it holds up where a surface-screwed dome stop gets kicked loose or unscrewed. Plan on a concrete or grout-anchorable floor and cure time before the door swings against it.

No. The 466 needs a 1 inch by 2-1/2 inch deep drilled hole packed with anchoring grout, so it wants concrete or a similar solid slab. On wood, tile over plywood, or any floor you cannot core and grout, use a surface mounted floor stop that screws down instead, such as the Ives FS13 brass floor dome stop or the Orca 23LP low rise dome stop.

A grouted-in floor stop like the Rockwood 466 is the usual answer. It has no exposed fasteners to unscrew or pry, and the bumper is a flame resistant high impact material rather than a soft rubber tip that gets torn off. Rockwood built it for high vandalism and security areas. A goose neck stop like the Delaney gooseneck or the Orca 22HD gives you a hold-open, but it sticks up and gives a foot something to bend.

The Rockwood 466 is a floor door stop, so it arrests the door swing and does not latch it open. To hold the door open you need a holder: the Ives FS40, FS41, FS42 and FS43 are heavy duty automatic floor stop and holder units with adjustable door-to-floor clearance, the Orca Hardware 22HD Series goose neck unit with black tip is catalogued with a door holder function for 1-3/8 inch or 1-3/4 inch doors, and the SOSS MDH is a heavy duty magnetic door holder and stop measuring 3-5/16 by 1-3/4 inches.

The Rockwood 466 mounts by drilling a 1 inch diameter by 2-1/2 inch deep hole and filling it with anchoring grout, which rules it out over post-tension slab, radiant tubing, or a topping too thin to take that depth. Surface-set floor bumpers cover that opening instead: the Deltana UFB4505 round universal floor door bumper at 1-1/2 inches in solid brass, the Deltana UFBS138 square universal floor door bumper at 1-3/8 inches in solid brass, or the Emtek 2254 floor door bumper at 1-3/8 by 1-1/4 inches. For a low profile stop the Orca Hardware 23LP Series dome floor stop is a low rise unit with a gray tip.

The Rockwood 466 is built for high vandalism and security areas and has no exposed fasteners, which is why it is grouted in rather than screwed down. The Ives FS18S and FS18L are the security floor stop pair in the heavy duty class and are the closest peer for that same tamper concern. The Ives FS13 and FS17 heavy duty brass floor dome stops are also heavy duty units, but they are catalogued as standard dome stops rather than as security stops.

Black, and that is the only finish. The whole unit is the flame resistant high impact bumper material, so there is no brass or plated cap to match to the rest of your hardware. If the stop needs to match a decorative finish package, a solid brass floor bumper such as the Deltana UFB4505 or the Emtek 2257 cylindrical floor bumper is the direction to look.

No. The 466 is a single piece, the flame resistant high impact bumper itself, so there is no replaceable rubber tip to specify and nothing to strip out of a socket. What you do supply on site is the anchoring grout for the 1 inch by 2-1/2 inch deep hole. If a field-replaceable bumper matters to you for long term maintenance, the Ives FS13 floor dome stop uses a replaceable rubber bumper.

The Rockwood 466 is finished in black and is a commercial unit. Where the stop has to match brass hardware in a lobby or a finer residence, the solid brass floor bumpers cover it: the Deltana UFBD3505 round universal floor bumper at 3-1/2 inches is a decorative solid brass unit, the Deltana UFBP4505 round universal floor door bumper has a pattern cap at 1-5/8 inches in solid brass, and the Deltana UFB4505 is the plain round 1-1/2 inch solid brass bumper. The Delaney dome door stop and the Emtek 2251 half dome door stop are the dome-profile options in that same decorative group.

They are not interchangeable even though both are floor-mounted and both measure 1-1/2 inches in one dimension. The Emtek 2257 is a 1-1/2 inch cylindrical floor bumper from the Emtek door accessories collection. The Rockwood 466 is a heavy duty commercial door stop with a flame resistant high impact bumper that installs by grouting into a 1 inch diameter by 2-1/2 inch deep drilled hole, so it leaves no exposed fasteners. If the spec calls for the grouted-in heavy duty stop, a surface bumper does not satisfy it.

The Rockwood 466 covers the openings where the floor can take a grouted 1 inch diameter by 2-1/2 inch deep anchor and the door bottom sits near the slab, and it is the right call in the high vandalism and security areas. Two other types usually round out the same building: an automatic floor stop and holder such as the Ives FS40, FS41, FS42 or FS43 with adjustable door-to-floor clearance for doors that must stand open, and the Ives FS18S or FS18L security floor stop where a tamper-resistant unit is wanted. The Ives FS13 dome stop carries a replaceable rubber bumper, which keeps the repeat maintenance item down to a tip.

Commercial. Rockwood specs the 466 for institutional buildings, offices, retail, educational, detention, sports facilities, hotel and restaurant work, and higher end residences. For a house where a grout-set stop is overkill, a screw-down dome or half dome such as the Emtek 2251 or the Delaney dome stop covers it.
