Rockwood 442 High Dome Stop

The 442 ships with #12 x 1-1/2 inch flat head wood screws and a plastic anchor. The anchor is what lets it go into concrete or masonry, drilled to suit; the wood screw alone is for a wood subfloor. Nothing else is needed to mount it.

Order it as 442 x EXP. That suffix gets you the exterior screw pack, stainless steel plated to match the finish, instead of the standard pack. The stop body itself is solid cast brass with a rubber bumper. Without the EXP suffix you get the standard fasteners.

It's certified to ANSI A156.16 and carries the L02161 type number, and it's classed as commercial hardware. That's the standard covering auxiliary hardware, and L02161 is the floor stop designation a spec writer or facility standard will call out.

The Ives FS13 is the nearest match. Both are brass floor dome stops with a rubber bumper, and the FS13 is rated heavy duty with a replaceable rubber bumper, so a worn tip can be swapped without pulling the base off the floor. The Rockwood 442 is solid cast brass with a rubber bumper and carries ANSI A156.16, L02161. The Ives FS17 is the other heavy-duty brass floor dome stop in the same family, with a rubber bumper that is not called out as replaceable. For a facility standardizing on one dome stop across many openings, the FS13 replaceable-bumper detail is the difference that matters over a long service life.

The 442 is a stop only; it arrests the door and nothing more. For hold-open, the Ives FS40 / FS41 / FS42 / FS43 automatic floor stop and holder is heavy duty with adjustable door-to-floor clearance, so it both stops the door and catches it open. The Orca Hardware 22HD Series goose neck floor stop with black tip is listed as a door holder and covers 1-3/8 inch or 1-3/4 inch door thickness. The SOSS MDH is a magnetic door holder and stop measuring 3-5/16 inch by 1-3/4 inch, heavy duty, which holds the door magnetically rather than mechanically. Choosing among these is a question of how the door is meant to be released.

Three: 605 bright brass, 613 oil rubbed bronze, and 626 satin chrome. Those are BHMA finish numbers, so 626 will match satin chrome levers and hinges on the same opening and 613 matches oil rubbed bronze trim. All three are on the same solid cast brass body.

A dome stop like the Rockwood 442 mounts in the floor at the door's swing arc and stops the leaf dead. It does not hold the door open. If you need the door to stay open, go to a holder: the Orca 22HD gooseneck is listed as a door holder, the Ives FS40/FS41/FS42/FS43 is an automatic floor stop and holder with adjustable door-to-floor clearance, and the SOSS MDH is a magnetic holder and stop. Gooseneck styles also stand well off the floor, which matters when the door needs to swing far past a wall.

The Ives FS17 is the direct counterpart, a heavy duty brass floor dome stop with a rubber bumper. The Ives FS13 is the same idea but with a replaceable rubber bumper, which is worth having on a high-traffic opening where the tip gets chewed up. On the decorative side, Deltana's UFB4505 is a 1-1/2 inch round solid brass floor bumper and the UFBD3505 is a 3-1/2 inch decorative version. Emtek's 2251 half dome is the residential-styled equivalent.

The base is 1-7/8 inches in diameter and the stop stands 1/2 inch off the floor. That's a small footprint, but any floor-mounted stop in a walking path is something people catch a toe on. In a corridor or an egress route, a wall-mounted stop or a magnetic holder like the SOSS MDH keeps the floor clear.

Solid cast brass body with a rubber bumper, certified commercial to ANSI A156.16. Rockwood hardware goes into institutional buildings, offices, retail, educational, detention, sports facilities, hotels and restaurants. For a stop that gets kicked daily, the Ives FS13 with its replaceable rubber bumper lets you renew the tip instead of pulling the whole stop.

The Rockwood 442 mounts with a #12 x 1-1/2 inch flat head wood screw and plastic anchor, which suits ordinary commercial openings. Where tampering is a concern - a detention corridor, a behavioral health unit, a school area with a history of vandalism - the Ives FS18S/FS18L security floor stop is the purpose-built heavy-duty option. Order the 442 with the EXP suffix (442 x EXP) if the exterior screw pack, stainless steel plated to match, is what the opening actually needs.

On a residential or light-traffic opening the profiles are comparable, but the two lines are specified differently. The Rockwood 442 is a commercial dome stop meeting ANSI A156.16, L02161, in solid cast brass. Emtek offers the 2251 Half Dome Door Stop, the 2254 floor door bumper at 1-3/8 inch by 1-1/4 inch, and the 2257 cylindrical floor bumper at 1-1/2 inch. Delaney also lists a Dome Door Stop in its dome stop series. If your submittal calls out an ANSI A156.16 stop, the 442 is the one that answers the spec.

It works as a fleet standard where the openings have thresholds or undercut doors, since that's the condition the high dome is sized for. Order the same finish across the building and use the EXP suffix on exterior doors so the screws match. One caution: the 442 stops the door, it does not hold it open, so any opening that needs to stay open takes a different part.

No handing on a dome stop. The 442 is a round stop, 1-7/8 inches in diameter, that mounts flat in the floor and takes the door on any face, so the same part works on left hand and right hand openings and on a pair of doors. Where you locate it on the floor is what sets the stopping angle.

The Rockwood 442 is a 1-7/8 inch diameter cast brass dome available in 613 oil rubbed bronze, 626 satin chrome, and 605 bright brass. For a larger or more ornamented footprint, Deltana's UFBD3505 is a 3-1/2 inch decorative round universal floor bumper in solid brass, and the UFBP4505 is a 1-5/8 inch round with a pattern cap, also solid brass. The larger diameter changes how much floor the unit occupies underfoot, which matters in a corridor or a guest room entry.
