Rockwood 471 Door Stop, Cast brass with rubber bumper, Plastic and Lead Anchor Fasteners

It meets ANSI A156.16 and carries the L02121 type designation, and it is specified as commercial hardware. That is the standard covering auxiliary door hardware, which is what a spec writer or facilities buyer needs to see on a submittal for an institutional opening.

Yes, but order it with the EXP suffix. Rockwood offers exterior pack screw packs, stainless steel plated to match the finish, specified as 470 x EXP when ordering. The standard pack is the interior fastener set, so an exterior or damp location wants the EXP screws to keep the fixings from rusting out around a brass body.

Stop only. The 471 has a rubber bumper that arrests the door swing and protects the wall, with nothing to catch and hold the leaf. If you want the door to stay put once it's open, you need a holder instead, such as the Orca Hardware TH-30HD, which is listed as a door holder. The Hager 212 is an adjustable rigid stop with an 80 to 120 degree range if you need to limit how far the door travels.

The Emtek 2231 baseboard door stop is the nearest match in form, at 4 inches. Both mount to the baseboard rather than the floor, so the door swing is arrested against the wall trim instead of a floor-set bumper. The Rockwood 471 is cast brass with a rubber bumper and measures 2-1/2 inch diameter by 3 inch height, and it meets ANSI A156.16, L02121. The Delaney solid brass baseboard door stop is the other baseboard-mounted brass option, adjustable from 3-1/2 to 4-1/2 inches, which suits a wall where the projection needs to be dialed in on site.

The 471 is a baseboard stop and needs trim to fasten into. Where there is no baseboard, a floor-mounted bumper takes the strike instead: the Delaney 2 inch height round solid brass floor bumper sets into the floor in the door's swing path and holds the same solid brass material. Where the door needs to be held open rather than only stopped, the Orca Hardware TH-30HD is a rigid door holder, and the Hager 212 is an adjustable rigid door stop covering an 80 to 120 degree range, both of which carry the load through an arm off the door face rather than the wall trim.

Two finishes: 613 satin bronze oil-rubbed and 626 satin chrome. If you're standardizing a corridor, 626 is the one that matches satin chrome and satin stainless lever trim, and 613 matches oil-rubbed bronze pulls and hinges. The body is cast brass under the finish with a rubber bumper face.

It's built for exactly that. The body is cast brass, not stamped or die-cast, and Rockwood specifies these for institutional buildings, offices, retail, educational, detention, sports facilities, hotels and restaurants. It's classified as commercial hardware to ANSI A156.16. In a high-traffic corridor the wear item is the rubber bumper, not the brass body.

The Rockwood 471 is a commercial-grade brass part certified to ANSI A156.16, L02121, which is the reference an institutional spec is usually written against. Among the alternatives, the Delaney baseboard door stop and the Delaney round floor bumper are both solid brass, so a facility mixing baseboard and floor locations can hold one material and finish family across both. The Hager 212 and the Orca TH-30HD are rigid units that stop and hold the door at a set position, which is a different function from a bumper and would be specified where doors need to stand open.

No. The 471 arrests the door where its cast brass body and rubber bumper meet the door face, and the stopping point is fixed by where the stop is anchored in the baseboard. To set the opening angle deliberately, the Hager 212 is an adjustable rigid door stop with an 80 to 120 degree range, and the Orca Hardware TH-30HD is a heavy-duty rigid unit that also functions as a door holder. If the requirement is only that the projection reach a wall standing off the door, the Delaney baseboard door stop adjusts from 3-1/2 to 4-1/2 inches, though it still stops at the wall rather than at a chosen angle.

The Rockwood 471 measures 2-1/2 inch diameter and 3 inch height. The Emtek 2231 baseboard door stop is 4 inches, and the Delaney solid brass baseboard door stop adjusts across a 3-1/2 to 4-1/2 inch range. Projection matters where a chair rail, radiator cover, or door pull would otherwise reach the wall before the stop does, so measure the clear distance from the baseboard face to the closest point on the swinging door before choosing between them.
