Rockwood 480 Door Stop, 1-5/8" Projection, 2-1/2" by 1-3/4" Base, Plastic Anchor Fasteners

That is what the 480 is built for. It's a solid cast brass floor stop with a rubber bumper, rated commercial, and Rockwood calls it heavy duty for use on heavy doors or in high traffic areas. The cast brass body is the reason: there's no stamped or hollow section to deform when a 3-hour-rated wood or hollow metal door swings into it a few hundred times a day.

It stands 1-5/8 inches high with a 2-1/2 by 1-3/4 inch base. That height is the number that matters: the stop has to catch the door leaf or the lever below the door's undercut, so measure from your finished floor to the bottom edge of the door and to whatever the stop will strike. On a door with a large undercut or a tall floor covering, 1-5/8 inches may pass under the leaf, and you'd want a taller riser or a wall stop instead.

Each 480 ships with 3 each #12-24 x 1-1/4 inch flat head wood screws and 3 plastic anchors. The plastic anchors are what let it go into concrete or masonry: drill for the anchor, set it, and drive the wood screws. Straight into wood subfloor you can skip the anchors. Nothing else is required to mount it.

Order it with the EXP suffix (480 x EXP) if it's going outside or anywhere damp. That gets you the exterior pack screw pack, stainless steel plated to match the finish, instead of the standard fasteners. The stop body itself is cast brass either way, but standard screws in an exterior slab are the part that rusts and stains the floor.

No. The bumper on the 480 is replaceable, part number 461B. That's the reason to spec a cast brass stop in a building you maintain: the brass body outlives several bumpers, and swapping a 461B is cheaper and faster than pulling anchors out of a slab. Bumpers come in standard gray or optional black.

No. The 480 is a stop only, cast brass with a rubber bumper, and it does nothing but arrest the swing. If you need the leaf to stay put, you want a 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 door holder and stop measuring 3-5/16 by 1-3/4 inches. Buying a stop when the spec calls for a holder is the most common mistake on this line item.

The 480 is a stop only - it arrests the door at 1-5/8 inches of projection and nothing more. For hold-open, the Ives FS40 / FS41 / FS42 / FS43 is a heavy-duty automatic floor stop and holder with adjustable door-to-floor clearance, so one part both stops and holds. The Orca Hardware 22HD Series goose neck floor stop with black tip is catalogued as a door holder and fits doors 1-3/8 or 1-3/4 inches thick. The SOSS MDH is a heavy-duty magnetic door holder and stop measuring 3-5/16 by 1-3/4 inches, which holds by magnet rather than by a mechanical catch.

The Rockwood 480 projects 1-5/8 inches, which is a low-rise dome profile. For a taller reach, the Deltana UFBD3505 is a 3-1/2 inch round universal floor bumper in solid brass with a decorative cap. Goose neck styles also gain height off the floor by design: the Delaney Gooseneck Floor Door Stop, the Emtek 2253 Goose Style Door Stop, and the Orca Hardware 22HD Series goose neck floor stop with black tip all use that arm profile. Going the other direction, the Orca 23LP Series is a low-rise dome floor stop with a gray tip.

A low dome stop like the 480 sits 1-5/8 inches off the floor and catches the bottom of the door leaf. It's the lower trip hazard and the easier one to mop around, but it only works if the door bottom actually reaches it. A gooseneck reaches up and out to catch the door face or the lever, which is what you want when the door has a big undercut, thick carpet, or a lever that would otherwise punch the wall. ZenSupply carries goosenecks including the Orca Hardware 22HD Series and the Emtek 2253 Goose Style. If you need the door to stay open rather than just stop, that's a holder, not a stop, and the Ives FS40 / FS41 / FS42 / FS43 automatic floor stop and holder covers that.

The Ives FS13 is the nearest match: a heavy-duty brass floor dome stop with a replaceable rubber bumper, same construction story as the 480 and the same serviceability. The Ives FS17 is also a heavy-duty brass floor dome stop with a rubber bumper. On the decorative side, Deltana's solid brass universal floor bumpers cover the same job in residential and light commercial trim, including the UFBP4505 with a pattern cap at 1-5/8 inches and the square UFBS138 at 1-3/8 inches. Match the height to your door's undercut before you pick on looks.

It fits that use. Rockwood hardware is normally used on institutional buildings, offices, retail, educational, detention, sports facilities, hotels and restaurants. Two practical reasons it standardizes well: the bumper is a stocked replaceable part (461B), so your maintenance crew carries one small item instead of whole stops, and the exterior version is the same model with an EXP suffix, so vestibule and exterior openings don't break the spec. Pick one finish, 626 satin chrome or 606 satin brass, to match the lever hardware and the whole fleet looks the same.

Three things to call out. Finish: 626 satin chrome or 606 satin brass. Bumper: standard gray unless you specify the optional black. Fasteners: the standard pack is 3 each #12-24 x 1-1/4 inch flat head wood screws with 3 plastic anchors, and if the opening is exterior you add the EXP suffix (480 x EXP) for the stainless steel plated exterior screw pack. Nothing else is an option on this stop.

The 480 is built for commercial service - solid cast brass, heavy duty, intended for heavy doors and high traffic areas. Where that is more stop than the opening needs, the round universal floor bumpers are a plainer solid brass option: the Deltana UFB4505 at 1-1/2 inches, the Deltana UFBS138 in a 1-3/8 inch square, and the Emtek 2254 floor door bumper at 1-3/8 by 1-1/4 inches. Emtek also lists the 2251 Half Dome Door Stop and the Delaney Dome Stop in the same simple dome form as the 480.

The Deltana UFBP4505 round universal floor door bumper with pattern cap is 1-5/8 inches, the same projection as the Rockwood 480, and it is solid brass. It is a round universal bumper with a decorative pattern cap rather than a dome stop with a replaceable 461B bumper, so the strike face and the serviceability differ even though the height off the floor is the same.

The 480 is a heavy duty stop for heavy doors and high traffic, mounted with 3 each #12-24 x 1-1/4 inch flat head wood screws and 3 plastic anchors. Where the concern is tampering rather than traffic, the Ives FS18S/FS18L is a heavy-duty security floor stop, built for that condition. Note that the 480 fastener pack is the standard interior set; Rockwood offers exterior pack screw packs stainless steel plated to match, ordered with the EXP suffix as 480 x EXP, for openings exposed to weather.

Two: 626 satin chrome and 606 satin brass. 626 is the standard match for most commercial lever and closer hardware, so if you're stopping doors in an office or school where the locks are 626, that's the one that disappears. 606 satin brass suits openings already trimmed in brass.

They serve the same purpose but are different parts. The Emtek 2257 is a 1-1/2 inch cylindrical floor bumper from the Door Accessories Collection - a straight cylinder that takes the door edge on its flat top. The Rockwood 480 is a dome stop with a 2-1/2 by 1-3/4 inch base and a 1-5/8 inch projection, using replacement bumper 461B, and is offered in 626 satin chrome and 606 satin brass. The wider base footprint and the replaceable bumper are the practical differences to check before swapping one for the other.
