Rockwood 462 Heavy Duty Door Stop

The 462 is a grouted-in floor stop, not a screw-and-anchor unit. You drill a 1 inch diameter hole 2-1/2 inches deep in the floor and fill it with anchoring grout to set the stop. That means you need a hammer drill and a masonry bit for concrete, plus grout, and you cannot relocate it later without breaking it out. If you need something you can pull and re-set, or install over wood or tile without coring, a surface-mounted stop like the Ives FS13 brass floor dome stop is the different approach.

Half an inch high with a 2 inch diameter. It is a low-profile dome, so it sits under the bottom rail of most doors and takes the strike on the face of the door rather than the edge. The low rise also keeps it out of the way of mop carts and wheeled traffic, which is why it suits corridors in schools and hospitals. Measure your door-to-floor clearance against that 1/2 inch before you core the hole; if the undercut is larger than the stop is tall, the door sweeps over it and the stop does nothing.

Stop only. The 462 is a bumper that arrests the door's swing; it has no hook, no catch, and no magnet, so the door falls back closed. For a door you need held open, look at the Ives FS40 / FS41 / FS42 / FS43 automatic floor stop and holder, the SOSS MDH magnetic door holder and stop, or the Orca 22HD gooseneck floor stop, which is a door holder. On a fire-rated opening, a door held open on a mechanical catch is generally not permitted, which is another reason a plain stop like the 462 is what gets specified in institutional corridors.

The Rockwood 462 requires drilling a 1 inch diameter by 2-1/2 inch deep hole and filling it with anchoring grout, which is a permanent commitment to the slab. Where that is not allowed or not practical, the Deltana UFB4505 round universal floor door bumper at 1-1/2 inch in solid brass and the Emtek 2254 floor door bumper at 1-3/8 inch by 1-1/4 inch are surface floor bumpers instead. The Deltana UFBS138 square universal floor door bumper at 1-3/8 inch is the square-profile equivalent in the same family.

The Ives FS13 heavy-duty brass floor dome stop with replaceable rubber bumper is the nearest peer in duty level. The Rockwood 462 stands 1/2 inch high with a 2 inch diameter and uses a flame resistant high impact bumper set into the floor. The FS13 is also a heavy duty dome stop, with the added feature that its rubber bumper is replaceable rather than integral, which matters where the strike face wears and you would rather change a bumper than pull the stop out of the slab. The Ives FS17 heavy-duty brass floor dome stop is the same family with a standard rubber bumper.

The Rockwood 462 is a floor stop: it arrests the door swing at 1/2 inch of height and a 2 inch diameter footprint, and does not latch the door open. For a hold-open, the Ives FS40, FS41, FS42 and FS43 automatic floor stop and holder offers adjustable door-to-floor clearance and is heavy duty, and the SOSS MDH magnetic door holder and stop at 3-5/16 inch by 1-3/4 inch is also a heavy duty holder. The Orca Hardware 22HD Series goose neck floor stop with black tip is listed as a door holder for 1-3/8 inch or 1-3/4 inch doors.

It is built for commercial use, with a flame resistant high impact bumper as the striking surface and a grouted-in anchor rather than a screw into the slab. Rockwood hardware of this kind goes into institutional buildings, offices, retail, schools, detention, sports facilities, and hotels. The grout set is the reason it holds up: there is no fastener to work loose under repeated slamming, which is the usual failure on a screwed-down stop in a busy corridor.

A floor stop like the Rockwood 462 is what you use when the door does not swing into a wall, or swings past one, so there is nothing at handle height to strike. The trade-off is that it lives in the walking path and, on the 462, requires coring a 1 inch hole 2-1/2 inches deep into the slab. Use a wall stop where a wall is in reach of the door's arc, since it keeps the floor clear. Where the door opens into an aisle or an open room, the floor stop is the only option that protects the wall and the lever trim.

Both are dome floor stops rather than holders. The 462 sets into a grouted 1 inch by 2-1/2 inch deep core, stands 1/2 inch high with a 2 inch diameter, and uses a flame resistant high impact bumper. The Orca 23LP Series is a low-rise dome floor stop with a gray tip. The practical split is the anchoring: a grouted 462 is permanent and has no fastener to loosen, so it is the choice for corridors that take constant abuse, while a surface-fixed dome is faster to install and can be moved.

No. The 462 ships as the stop itself; the anchoring grout that sets it in the floor is a jobsite material you supply. Plan on a hammer drill, a 1 inch masonry bit long enough to reach 2-1/2 inches, and grout on hand before the crew shows up. There is no anchor, screw, or expansion shield to specify, since the grout is the anchor.

The grouted-in 462 is itself the tamper answer within Rockwood's floor stops: with no exposed fastener and the body set in grout in a 1 inch by 2-1/2 inch core, there is nothing to unscrew or pry, and its 1/2 inch height gives a foot little to catch. Rockwood hardware of this type is used in detention and educational facilities. If you want a purpose-built security unit instead, the Ives FS18S/FS18L security floor stop is the heavy duty option in that family.

They stop the door in different places. The Rockwood 462 is a low 1/2 inch high, 2 inch diameter dome that is grouted into the floor and takes the strike near the bottom edge of the door. A gooseneck stop such as the Delaney gooseneck floor door stop, the Emtek 2253 goose style door stop, or the Orca Hardware 22HD Series goose neck floor stop with black tip rises on a curved arm to meet the door face higher up, and the Orca version functions as a door holder for 1-3/8 inch or 1-3/4 inch doors. Gooseneck profiles reach a door that clears the floor by more than a dome can bridge; the low dome keeps the walking surface clear.

The Rockwood 462 is already low at 1/2 inch high with a 2 inch diameter. If you want the same idea in a low rise dome, the Orca Hardware 23LP Series dome floor stop with gray tip is a low rise dome stop. The Delaney dome door stop and the Emtek 2251 half dome door stop are the other dome profile peers. Dome stops of this kind sit close to the walking surface and present no arm above the floor line, unlike a gooseneck.

The Rockwood 462 is a commercial heavy duty stop and its grouted 1 inch by 2-1/2 inch anchor makes it hard to pull out of the floor, which is why Rockwood products are used in institutional, educational and detention buildings. Where the specification calls out a security floor stop by name, the Ives FS18S and FS18L security floor stop is the heavy duty peer built for that call-out. Both resist abuse; the FS18S/FS18L is the one that will match a drawing that says security floor stop.

The Rockwood 462 is a plain heavy duty dome in US2C, 1/2 inch high by 2 inch diameter, built for traffic rather than for show. For a decorative finish-side look, the Deltana UFBD3505 round universal floor bumper at 3-1/2 inch is a decorative solid brass unit, and the Deltana UFBP4505 round universal floor door bumper with pattern cap at 1-5/8 inch carries a patterned cap in solid brass. The Emtek 2257 1-1/2 inch cylindrical floor bumper comes from a door accessories collection intended to coordinate with matching trim.

They are not the same class of part. The Rockwood 462 is a commercial heavy duty door stop that is grouted permanently into the slab with a 1 inch by 2-1/2 inch anchor hole and a flame resistant high impact bumper. Products such as the Deltana UFB4505 round universal floor door bumper at 1-1/2 inch in solid brass and the Deltana UFBS138 square universal floor door bumper at 1-3/8 inch are universal floor bumpers that cushion the door where it lands. If the drawing calls for a heavy duty floor stop, the Ives FS13 heavy-duty brass floor dome stop is the peer to cross to rather than a universal bumper.

The Rockwood 462 is a commercial heavy duty door stop. Among the cross-brand options, the Ives FS13 brass floor dome stop with replaceable rubber bumper, the Ives FS17 brass floor dome stop with rubber bumper, the Ives FS18S and FS18L security floor stop, the Ives FS40, FS41, FS42 and FS43 automatic floor stop and holder, and the SOSS MDH magnetic door holder and stop are all heavy duty. That gives one family covering a plain stop, a security stop, a hold-open and a magnetic holder if you want a single heavy duty standard across mixed openings.

The Rockwood 462 is fixed in the floor at a 1 inch diameter by 2-1/2 inch deep grouted hole, so it only works where the slab under the door swing can take the anchor and the 1/2 inch high dome reaches the door. Where the door needs to be caught and held at the wall or off the floor line instead, the SOSS MDH magnetic door holder and stop at 3-5/16 inch by 1-3/4 inch is a heavy duty magnetic option, and the Ives FS40, FS41, FS42 and FS43 automatic floor stop and holder adjusts door-to-floor clearance to suit the gap under the door.

One finish only, US2C. That is the sole model offered in the 462, so if you are matching a building standard to a specific plated finish across other openings, check that US2C is what the rest of the hardware carries before you commit. On a floor stop set into the slab, finish matters less than it does on visible trim, since only the 2 inch dome shows above the floor line.

Rockwood model 462, ordered as 462-US2C. There is a single configuration, so there is no handing, size, or finish suffix to work out on the order. If you are standardizing a building, that single part number covers every opening that takes a grouted-in floor stop.
