Rockwood RM860 Convex Wall Mounted Door Stop

1-3/32 inches. That is the projection of the RM860 convex wall bumper measured off the finished wall, so whatever contacts the pad, a lever end or the door face, stops that far short of the wall. It is a shallow stop, which suits an opening where the door swings close to the wall and all you need is to keep the hardware from marking the paint. If the lever, a closer arm, or a panic device pushes further out than that, this one lands too late and you want a longer wall stop: ABH's RM Series and RMS Series wall door stops are offered in multiple lengths.

Convex. The RM860 bumper face is domed, so it takes the hit from a flat surface, either the door face itself or the flat back of a lever rose. A concave bumper is dished instead, so it cups a round knob and keeps it from sliding off the pad. Knobs on the doors, look at a concave bumper such as the Delaney 2-1/4 inch concave wall bumper. Levers, or you are stopping the door face, and convex is the one you want.

The RM860 ships with a #8 x 1-1/4 inch TH SMS fastener, a truss head sheet metal screw, plus a plastic toggle. The toggle is the hollow-wall anchor, so drywall with nothing behind it is covered out of the box. Land on a stud or on blocking and the screw drives straight in, toggle unused. Concrete, block, or tile takes a masonry anchor you supply, and if you would rather order a stop specified for both wall types, the Ives WS11 heavy duty wall stop is listed for drywall and masonry.

The nearest peers are the Ives WS33/WS33X heavy-duty wall door stop with replaceable rubber bumper and the Ives WS11/WS11X heavy duty wall stop with replaceable rubber bumper for drywall and masonry. All three are surface wall-mounted bumpers that catch the door leaf before it drives the lever or knob into the wall. The Rockwood RM860 is a convex bumper on a 1-5/8 inch base with 1-3/32 inch projection and a 2-7/16 inch overall diameter, uses concealed mounting so no fastener heads show on the face, and carries a back plate that spreads impact and prevents damage to the wall. The two Ives units are built around a rubber bumper that can be swapped out on its own, and the WS11 is described for both drywall and masonry walls. If the opening is a straightforward commercial swing door striking a stud or toggled drywall wall, the RM860 and the WS33 cover the same job.

It depends on what hits the pad. The Rockwood RM860 uses a convex bumper, a domed face that meets a flat door face or the flat back of lever trim squarely across the crown. A concave bumper is dished instead, so a round knob seats into the cup and cannot slide off the pad and skate into the wall. The Delaney 2-1/4 inch concave wall bumper is the concave choice among comparable wall stops. Determine the contact point before ordering: stand the door where you want it to halt and look at what touches the wall first. Round knobs favor concave; lever trim, escutcheon plates, and bare door faces favor the convex RM860, which projects 1-3/32 inch off the wall on a 2-7/16 inch diameter base.

The Rockwood RM860 is a bumper only. It cushions the door at the wall and lets it swing back on its own, which is what most corridor and office openings want. When the door needs to stay parked open, the comparable set has two wall holders. The Ives WS20/WS20X is a manual wall holder with a hinged strike, so the strike is flipped down by hand to catch and hold the door, and it is described for drywall and masonry applications. The Ives WS40 is an automatic wall holder with a heavy duty bumper pad that catches the door on contact without anyone bending down, and it is rated light duty. One caution on the swap: a rated fire door assembly has to be self-closing, so a mechanical hold-open is generally not acceptable there and the bumper is the correct part.

The Rockwood RM860 projects 1-3/32 inch from the finished wall, which suits an opening where the door face or lever trim arrives close to the wall plane. Where the trim stands further off the door, or a thick wall base pushes the contact point outward, the bumper has to reach further. The ABH RM Series wall door stops and the ABH RMS Series wall door stops are both offered with multiple length options, so the projection can be matched to the actual gap rather than to a fixed dimension. To size it, swing the door to where you want it to stop, then measure from the finished wall surface to the highest point of the trim that would otherwise strike, and pick a length that meets that trim before anything else touches.

Not the RM860. It mounts to the wall and needs wall surface where the door lands, so a door that opens into open room or swings past the end of the wall has nothing to hit. Go to a stop that mounts low at the base of the wall or on the baseboard instead: Delaney's 3 inch spring door stop flexes as the door strikes it, and the Delaney 3 inch heavy duty rigid door stop takes the hit without giving.

Depends where they sit. The RM860 has a 1-5/8 inch base and a 2-7/16 inch product diameter, and it goes up on the supplied #8 x 1-1/4 inch screw and plastic toggle, so it wants one sound anchor point roughly where the old one was. Land it on the previous hole and you are done. Land it anywhere else and the old hole is still showing under the paint, and the Delaney 2-1/8 inch hole plate metal cover is what we carry to cap it.

It is a commercial-designated stop, and the back plate behind the bumper is there to spread repeated impact across the wall rather than concentrate it on one screw in the drywall. Mounting is concealed, so there is no exposed fastener for a maintenance crew to keep chasing. If you are standardizing across openings that get hammered daily and you want the pad itself to be a wear part, the Ives WS11 and Ives WS33 are both listed heavy duty with a replaceable rubber bumper, so the pad gets swapped without pulling the stop off the wall.

No. The RM designation appears in both lines, but they are two manufacturers' catalog numbers and they are not interchangeable on paper. Rockwood's RM860 is a single convex wall bumper with a 1-5/8 inch base, 1-3/32 inch projection, and a 2-7/16 inch diameter, supplied in satin chrome, 626. ABH's RM Series and its companion RMS Series are wall door stop lines offered with multiple length options, so a single ABH line number covers a range of projections rather than one fixed dimension. When quoting or receiving, match brand plus full part number plus finish code, since an RM alone will pull the wrong line.

No. The Delaney 2-1/8 inch hole plate metal cover is a blank cover plate that conceals an unused prepped hole. It has no bumper and is not built to absorb a door strike. The Rockwood RM860 is a convex wall bumper with 1-3/32 inch projection and a back plate that prevents damage to the wall, so it takes the impact and stands the door off. The two get confused because both are small round metal discs of similar size, 2-7/16 inch diameter for the RM860 against 2-1/8 inch for the Delaney plate. They pair rather than compete: if an old stop is being pulled and relocated, the plate covers the abandoned hole and the RM860 does the stopping at the new location.

The Rockwood RM860 is wall mounted and comes with a #8 x 1-1/4 inch TH SMS fastener and a plastic toggle, which anchors it in hollow drywall between studs. Where that wall surface is off limits, tile, glazing, a millwork panel, or a chase you do not want opened, move the stop down to the base instead of onto the wall. The Delaney 3 inch HD rigid door stop and the Delaney 3 inch spring door stop both catch the door low, at the baseboard or floor, well clear of the wall finish. The rigid version is a solid post that halts the door dead; the spring version flexes on a coil so the door decelerates rather than bounces. Both stop the door at the bottom rail, so check that the door has no undercut or sweep that would ride over the stop.

The Rockwood RM860 arrives with a #8 x 1-1/4 inch TH SMS fastener and a plastic toggle, a hollow-wall set sized for drywall, and it mounts concealed so the fasteners do not show once it is on. Where a facility mixes drywall partitions with CMU or concrete and a single line item is wanted for the whole run, the Ives WS11/WS11X heavy duty wall stop is described for drywall and masonry, and the Ives WS20/WS20X wall holder is described for drywall and masonry applications as well. On a standardization package, walk the openings first and count how many actually land on masonry; a mixed building often ends up with the RM860 on the partition walls and a masonry-rated unit only where the stop falls on block.

Two peers call this out directly: the Ives WS11/WS11X heavy duty wall stop and the Ives WS33/WS33X heavy-duty wall door stop are both built with a replaceable rubber bumper, so a worn or torn pad comes off without pulling the base off the wall. That matters on high-traffic openings where the pad is the wearing part and the anchor is not. The Rockwood RM860 is a convex bumper carrying a back plate that prevents damage to the wall behind it and mounts concealed with a #8 x 1-1/4 inch TH SMS fastener and plastic toggle, a set that pulls and resets cleanly if a unit is ever swapped. For a maintenance shop stocking spares, decide whether you would rather stock replacement pads or complete units, since that choice, more than the stop itself, drives which line you standardize on.

No. The RM860 uses concealed mounting, so the fastener sits behind the bumper instead of through the face of it, and what a tenant sees is a clean satin chrome dome. The back plate behind it spreads the impact into the wall rather than driving it into a single point of drywall, which is what keeps a bumper on a busy opening from working itself loose.

One finish, 626 satin chrome. That is the standard finish code for satin chrome and the most common commercial finish on levers, closers, and exit hardware, so it sits alongside 626 lockset trim on the same openings without looking out of place. Worth knowing before you order for a whole building: 626 and 630 satin stainless are different finishes and do not always read the same next to each other, so match the code on the door hardware you already have rather than the description.

The Emtek 2255 is a brass wall bumper with a regular rosette, so the trim ring is part of the visible design and it reads as residential decorative trim. The Rockwood RM860 is a commercial convex bumper supplied in satin chrome, 626, with concealed mounting that leaves a clean face and a back plate that prevents damage to the wall, on a 2-7/16 inch diameter base with 1-3/32 inch projection. Functionally both park the door off the wall. The deciding factor is which trim family the rest of the opening follows: a brass rosette to match knobs and hinges in a decorative package, or the 626 commercial finish that lines up with standard lever and closer hardware.
