Rockwood 445 Heavy Duty Door Stop, 1-1/8" Height, 2" by 4" Base

That is what the 445 is built for. It is an extra heavy duty dome type stop intended for heavy and high frequency doors, made from solid cast brass with a rubber bumper, and it is a commercial-grade part rather than a residential one. On an entry that gets hundreds of swings a day, a cast brass body is what keeps the stop from deforming where a hollow or stamped bumper would.

The 445 measures 2 x 4 x 1-1/8 inches, so it stands 1-1/8 inches tall. That height is what decides whether it works for you: the stop has to be taller than the undercut between your door bottom and the finished floor, or the door rides over it. On doors with a large floor clearance, a taller riser or a wall-mounted stop is the better call.

Fasteners are in the box for both common floor types. You get 2 each of #12 x 1-1/2 inch flat head sheet metal screws with a plastic anchor for masonry or concrete, plus a #12-24 x 1 inch flat head machine screw and anchor. That covers a wood subfloor and a drilled concrete or tile floor without a separate trip to the fastener aisle.

Yes, with the right screw pack. Rockwood offers exterior pack screws for the 445, stainless steel plated to match the finish, and you specify them with the EXP suffix (ordered as 445 x EXP). The standard pack is fine indoors; on an exterior door, a loading dock, or a pool or shower area, the plated exterior fasteners are what keep the mounting screws from rusting out under a brass stop.

A dome stop like the Rockwood 445 sits low on the floor, 1-1/8 inches tall, and stops the door where the door bottom meets it. It is the low-profile choice and a smaller trip hazard, but it needs the door undercut to be less than that height. A gooseneck stop reaches up from the floor and catches the door face higher, which is the answer when the floor clearance is too big for a dome. ZenSupply carries goosenecks such as the Delaney Gooseneck Floor Door Stop and the Orca Hardware 22HD Series goose neck floor stop.

The Ives FS13 is the nearest match. It is a heavy-duty brass floor dome stop with a replaceable rubber bumper, the same dome-stop format as the Rockwood 445, which is solid cast brass with a rubber bumper on a 2 inch by 4 inch base standing 1-1/8 inch tall. The Ives FS17 is the other heavy-duty brass floor dome stop in the same family, carrying a rubber bumper as well. Where the FS13 differs is that its bumper is called out as replaceable, which matters on high-traffic openings where the rubber wears before the casting does.

Use a gooseneck stop, which stands up off the floor and reaches the door face well before a low dome does. The Orca Hardware 22HD Series goose neck floor stop with black tip fits doors 1-3/8 inch or 1-3/4 inch thick and functions as a door holder. The Emtek 2253 Goose Style Door Stop and the Delaney Gooseneck Floor Door Stop are the same upright format. The Rockwood 445 is a dome type stop only 1-1/8 inch tall on a 2 inch by 4 inch base, so it catches the bottom edge of the door rather than standing up to meet it.

Yes. Rockwood hardware is used on institutional buildings, offices, retail, educational, detention, sports facilities, hotel and restaurant work, and higher-end residences, and the 445 is classed commercial. For a facility standardizing floor stops across hundreds of openings, the cast brass body and the two architectural finishes make it a repeatable spec.

It depends on the door. Small solid brass bumpers such as the Deltana UFB4505 at 1-1/2 inches, the Deltana UFBS138 square bumper at 1-3/8 inches, or the Emtek 2254 at 1-3/8 x 1-1/4 inches are made for light interior and residential doors and decorative work. The Rockwood 445 is the extra heavy duty answer for heavy, high frequency doors, with a 2 by 4 inch base and cast brass construction. Put the bumper on a bedroom door and the 445 on a stairwell or corridor door.

Rockwood hardware is specified in detention facilities, and the 445 is an extra heavy duty cast brass stop, so it holds up better than a light bumper. But it mounts with #12 screws and anchors, which is a standard fastening rather than a tamper-resistant one. Where the concern is someone deliberately prying the stop off the floor, look at a security floor stop instead, such as the Ives FS18S/FS18L security floor stop.

The Delaney Dome Door Stop is the same dome-stop format in a lighter line, and the Orca Hardware 23LP Series is a low-rise dome floor stop with a gray tip. Emtek offers the 2251 Half Dome Door Stop in the same silhouette. The Rockwood 445 is built as an extra heavy duty dome type stop for heavy and high frequency doors in solid cast brass, and is designated for commercial use, so on an apartment interior door the lighter dome stops cover the same job in a smaller casting.

The Ives FS18S and FS18L are heavy-duty security floor stops, built for openings where the stop itself is a target. The Rockwood 445 is an extra heavy duty dome type stop in solid cast brass with a rubber bumper, intended for heavy and high frequency doors, and Rockwood hardware of this kind is used across institutional, detention, educational and sports facility work. For a detention or high-abuse corridor the FS18S/FS18L is the security-specific option; for general high-traffic institutional openings the 445 is the heavy duty dome stop.

The Rockwood 445 is a fixed-height dome stop at 1-1/8 inch on a 2 inch by 4 inch base, so the strike height does not adjust. Where door-to-floor clearance varies opening to opening, the Ives FS40, FS41, FS42 and FS43 are heavy-duty automatic floor stops and holders with adjustable door-to-floor clearance, which lets one part number cover a range of gaps. Standardizing a fleet of doors on a fixed dome stop works when the undercut is consistent.

The base footprint is 2 by 4 inches, with an overall size of 2 x 4 x 1-1/8 inches. That is a larger pad than a small round bumper, which is the point on a heavy door: it spreads the impact load over more of the floor and gives you two anchor points instead of one. Worth checking against tile joints or a carpet edge before you drill.
