Rockwood 461L Kick Down Door Stop, 5" Projection

The 461L handles up to 3 inches of door-to-floor clearance, with a 5 inch projection when kicked down. If your undercut is bigger than 3 inches (common where thick carpet was pulled or a threshold was removed), the rubber shoe won't reach the floor and you need a different hold-open. Measure from the bottom of the door leaf to the finished floor before ordering.

It carries ANSI A156.16, L01382. The L01382 type number is the line item a spec writer or institutional buyer puts on a hardware schedule, so it drops straight into a submittal without substitution paperwork.

No. The rubber bumper on the 461L is a replaceable part, No. 461B, so a worn or flattened shoe is a bumper order, not a new holder. On high traffic openings, buying spare 461B bumpers up front keeps the same holders on the door for years. The bumper comes in gray or black.

Closest cross-brand equivalents ZenSupply stocks are the Ives FS452 and FS455, both heavy duty kick down holders, the FS455 in brass with a 4 inch extension and non-marring rubber shoe. The Ives FS455A is the same 4 inch holder in satin aluminum. Orca Hardware's kick down holder runs a 5.275 inch reach if you need more drop than the Ives units. Delaney's kick down stop/holder in satin chrome US26D is the simpler option. Note the reach differences: the 461L projects 5 inches, the Ives 4 inch units less, so on a high-clearance door they are not interchangeable.

The Ives FS455 is the nearest match. It is a brass kick down door holder with a non-marring rubber shoe, the same cast brass body and rubber floor contact as the Rockwood 461L, which is solid cast brass with a rubber bumper. The FS455 carries a 4 inch extension where the 461L has a 5 inch projection, so on a door with more floor clearance the Rockwood reaches further down. Both use the same footprint approach: kick the arm down, the rubber shoe grips the floor and holds the door.

The Rockwood 461L has a 5 inch projection and is rated for doors with up to 3 inch door-to-floor clearance. The Orca Hardware 40ST series kick down door holder measures 5.275 inches, the longest reach in the group. The Ives FS455 and FS455A both extend 4 inches, so on a tall undercut or a threshold-free opening those two are the ones most likely to come up short.

The Rockwood 461L is the one to write on the schedule. It is a commercial product certified to ANSI A156.16 under type number L01382, so a spec writer or an inspector can match it against the drawing by type number. Among the alternatives, the Ives FS452, FS455 and FS455A are each described at a heavy duty level, and the Delaney 40280X and Orca 40ST series are identified by series rather than by an ANSI type number - useful where the job calls for a functional holder rather than a numbered one.

The base measures 2-1/4 x 1-1/4 inches, so it takes very little face real estate and mounts low on the door where it clears rails and glass stops. It fixes with four #8 x 3/4 inch oval head sheet metal screws, which come with it. Those are sheet metal screws, so on a solid wood door they bite directly, and on a hollow metal door you are threading into the skin.

Different jobs. A kick down like the 461L holds the door open on demand and lets it swing free the rest of the time, which is what you want for moving furniture, deliveries, or airing out a unit. It does not protect the wall. If the problem is the lever punching drywall, you want a wall or floor stop instead. Plenty of openings get both: a stop to catch the swing and a kick down to hold it.

It's a commercial-grade part, solid cast brass with a rubber bumper, and Rockwood specifies it for institutional buildings, offices, retail, schools, detention, sports facilities, and hotels. The cast brass body is what separates it from stamped residential holders that bend the first time someone kicks the door open with a cart.

It's built for fleet standardization: one model number, 461L, one ANSI type L01382, two finishes, and a single replacement bumper part (461B) to stock for the whole building. That means maintenance carries one spare part instead of five, and any new opening added later matches what's already hung. The 5 inch projection covers doors with up to 3 inches of floor clearance, which will take in most of a typical building's openings.

Both are 4 inch heavy duty kick down door holders. The FS455 is brass with a non-marring rubber shoe; the FS455A is satin aluminum. So the choice between them is the body material and finish, not the reach or the duty level. Against them, the Rockwood 461L is solid cast brass with a rubber bumper and comes in 613 satin bronze oil-rubbed and 626 satin chrome.

The Rockwood 461L is offered in 626 satin chrome, and the Delaney 40280X kick down door stop/holder is a satin chrome US26D unit, which is the same finish under the older US designation. If the rest of the door hardware on the floor is oil-rubbed bronze instead, the 461L is also offered in 613 satin bronze oil-rubbed, while the Ives FS455A comes in satin aluminum.

Not exactly. The FS452 is a heavy duty kick down door holder built with a stainless steel spring - a spring-loaded arm rather than the 461L's concealed-axle assembly with its rubber bumper gripping the floor. Both hold a door open at the floor, but the mechanism and the replacement parts differ: the 461L takes bumper No. 461B when the rubber wears. If the goal is to keep one bumper part number stocked across a building, staying with the 461L keeps that consistent.

The foot is rubber, which is what gives it grip on hard floors rather than sliding out from under the door. Rockwood also conceals the axle inside the base on this model, so there is no exposed pivot pin to collect grime or snag a mop. On sealed concrete and polished tile the rubber is doing all the work, so keep a spare 461B bumper on hand once the tread wears smooth.

There's no handing to specify. The 461L is ordered by finish only, 613 or 626, and it mounts on the push face of the door near the bottom, on whichever side the door swings open. Same part works on a left hand or right hand opening.

The Rockwood 461L is a commercial door stop, certified to ANSI A156.16 as type L01382 and built as solid cast brass with a rubber bumper. The Ives FS452, FS455 and FS455A are all classed as heavy duty. The Delaney 40280X and Orca 40ST series are catalogued by series without a stated duty level, so for a high-traffic corridor or an entry door that gets propped daily, the Rockwood and the three Ives units are the ones carrying an explicit rating.
