Rockwood 461 Kick Down Door Stop, 3-5/8" Projection

The 461 is a kick down holder that swings down from the door face and grips the floor on a rubber bumper. With 3-5/8 inches of projection below the base it reaches down to the floor, and the rubber tip is what does the holding, so it works by friction rather than by dropping into anything in the floor. On hard floors that friction is what you want. On carpet the bumper still bites, but a deep pile eats into the effective projection, so measure from the bottom of the door to the top of the pile before you commit to it on a carpeted opening.

Cast brass 461 carries ANSI A156.16, L01382. A156.16 is the auxiliary hardware standard that covers door stops and holders, and the L-code is the specific type designation, so if a spec on your drawing calls for an L01382 door holder this answers it directly. It is a commercial-grade item, not a residential one.

Yes. The 461 takes replacement bumper No. 461B, so a worn tip is a parts swap and not a reason to pull the whole holder off the door. For a property manager running a lot of these across a building, stocking a few 461B bumpers is cheaper maintenance than replacing units.

Projection on the 461 is 3-5/8 inches, measured from the mounting base out to the working end of the bumper. Mount the base so the bumper clears the floor when it is swung up, and so that at 3-5/8 inches it makes solid contact when kicked down. The practical check on site is the undercut plus any floor covering: on an opening with a big undercut over a thick mat or carpet, you may need more reach than the 461 gives, in which case a longer holder such as the Ives FS455 at 4 inches or the Orca 40ST at 5.275 inches is the better fit.

The Ives FS452 kick down door holder is the nearest peer to the Rockwood 461. Both are kick down floor holders that pivot down from a door-mounted base onto the floor, and both are built for commercial traffic - the 461 is a commercial-duty stop meeting ANSI A156.16, L01382, while the FS452 is rated heavy duty and uses a stainless steel spring. If you are matching an existing 461 on a fleet of doors, note the 461 projects 3-5/8 inches from the door face, so confirm the FS452 reaches your floor gap before mixing the two on the same openings.

The Rockwood 461 is the one to write in when the drawing cites the standard: it is a commercial kick down door stop meeting ANSI A156.16, L01382. Among the alternatives, the Ives FS452, FS455 and FS455A are each rated heavy duty. If the specification language is the ANSI designation itself rather than a duty description, the 461 carries the L01382 call-out directly.

The 461 base measures 2-1/4 x 1-1/4 inches and mounts with four #8 x 3/4 inch oval head sheet metal screws, which ship with it. Those screws are sized for a hollow metal or wood door face, and the 3/4 inch length means they stay inside the door skin rather than passing through. The axle is concealed inside the base, so there is no exposed pin to catch or work loose.

Three finishes: 613 satin bronze oil-rubbed, 626 satin chrome, and 606 satin brass. Those are standard BHMA finish numbers, so a 626 holder matches 626 hinges, pulls and lock trim on the same opening without eyeballing it. The body is solid cast brass under the finish. The rubber bumper itself comes in gray or black and is a separate visual element from the metal finish.

Both give you the same finish family. The Rockwood 461 in 626 satin chrome is solid cast brass and carries ANSI A156.16, L01382, and it comes with the four #8 x 3/4 inch mounting screws. The Delaney kick down stop/holder is offered in satin chrome US26D, which is the same finish under the old US designation. If the job is spec driven and the drawing calls out an A156.16 L-code, the Rockwood is the one that answers it on paper.

The naming is where buyers get caught. The Rockwood 461 is a kick down door stop with a rubber bumper that grips the floor, so kicking it down holds the door open at that point. The Orca Hardware 40ST Series unit is catalogued with a door holder function, and the Ives FS452, FS455 and FS455A are all named as door holders. In the kick down format these do the same job at the opening - the arm swings down and friction against the floor keeps the leaf where you put it. What actually separates them for a spec is reach and material, not the stop-versus-holder wording: the 461 is solid cast brass with a rubber bumper, the FS455 is brass with a non-marring rubber shoe, and the FS455A is satin aluminum.

Yes. The Rockwood 461 is offered in 626 satin chrome alongside 606 satin brass and 613 satin bronze oil-rubbed. The Delaney kick down door stop/holder is a satin chrome US26D unit, which is the same finish designation under the older US system. If a facility is standardized on satin chrome lever trim and pulls, either will read as a match on the door; the 461 carries a 2-1/4 inch by 1-1/4 inch base and a 3-5/8 inch projection if the base footprint matters where it lands on the stile.

Floor finish drives this choice more than anything else. The Rockwood 461 lands on a rubber bumper that grips the floor, and its replacement bumper is part No. 461B, so the wear item can be swapped without pulling the stop off the door. The Ives FS455 uses a non-marring rubber shoe on a brass body. Both put rubber rather than metal against the surface, which is what you want on VCT, sealed concrete, or finished wood in a corridor.

It is a commercial item built from solid cast brass with a rubber bumper, and Rockwood hardware of this line is used across institutional buildings, offices, retail, education, detention, sports facilities, and hospitality. The wear part is the rubber tip, and that is replaceable as the 461B, so high-traffic openings can be maintained rather than re-hardware.

Treat it as a new install rather than a drop-in. The Rockwood 461 mounts with 4 each #8 x 3/4 inch oval head sheet metal screws through a 2-1/4 inch by 1-1/4 inch base, and its assembly conceals the axle in the base. The Ives FS452, FS455 and FS455A are separate designs with their own bases, so hole patterns will not line up by default. On a re-hardware run across a building, put the 461 on all the doors in a wing rather than alternating brands, and you will only be filling and re-drilling once per leaf.
