Rockwood 518 3-3/4" Cast Brass Rigid Door Stop

The 518 has a 3-3/4 inch projection, measured from the mounting surface to the face of the rubber bumper. That is the number that decides whether the door clears whatever sits behind it, a lever handle, a thermostat, a panic push bar. If the trim on your door projects more than 3-3/4 inches from the door face, the hardware will hit the wall before the stop does and you need a longer projection or a floor-mounted stop instead.

Fixed. The 518 is a rigid stop at a set 3-3/4 inch projection, so what you order is what you get on the wall. If the gap between your baseboard and the door hardware is uncertain, or you are covering a run of openings with different trim depths, an adjustable baseboard stop like the Delaney solid brass unit that adjusts from 3-1/2 to 4-1/2 inches gives you room to dial it in on site.

They mount the same way but behave differently. The Rockwood 518 is a rigid cast brass stop, so the body does not flex and the rubber bumper absorbs the contact. The Sure-Loc 3-3/4 inch spring door stop and the Orca Hardware 3-3/4 inch spring door stop use a coiled spring body that gives when the door strikes it. Spring stops are more forgiving of an overswung door, while a rigid stop holds the door at a fixed point with no rebound. Sure-Loc describes its spring stops as residential door stops, so for institutional and high-traffic commercial openings the rigid cast brass 518 is the heavier-duty choice.

The Rockwood 518 is a cast brass rigid baseboard stop with a 3-3/4 inch projection. The closest like-for-like alternatives are the Emtek 2231 baseboard door stop at 4 inches, and the Delaney solid brass baseboard stop, which is adjustable from 3-1/2 to 4-1/2 inches. All three mount to the baseboard and hold the door off the wall; the Delaney's adjustable range lets one part cover openings where the required projection varies from door to door, while the Rockwood 518 and Emtek 2231 are fixed lengths. Confirm the measured distance from the baseboard to the door face before choosing a fixed-projection stop.

Use an adjustable baseboard stop. The Rockwood 518 is a fixed 3-3/4 inch projection, so it suits openings where the baseboard-to-door distance is consistent. The Delaney solid brass baseboard door stop adjusts from 3-1/2 to 4-1/2 inches, so a single part number covers a spread of conditions. The Hager 212 is an adjustable rigid door stop with an 80 to 120 degree range, which sets how far the door swings open rather than the projection length. Property managers standardizing across mixed trim depths often find the adjustable version reduces the number of SKUs they stock.

The Rockwood 518 is a door stop, not a holder. It limits the swing and cushions the door against the wall with a rubber bumper, but it does not latch the door in the open position. If you need the door to stay open, the Orca Hardware TH-30HD is a heavy-duty rigid unit whose function is a door holder. Specify the holder where you need hands-free open doors for moving carts or equipment, and the 518 where the only requirement is protecting the wall.

Yes, it ships with 2 each #8 x 3/4 inch oval head sheet metal screws. Those are sized for wood baseboard; if you are anchoring into a metal stud, block wall, or hollow base, plan on supplying your own anchors because the included SMS will not hold in those substrates.

No. The 518 stops the door, it does not hold it open. If you need the door captured in the open position, the Orca Hardware TH-30HD is a heavy duty rigid unit catalogued with a door holder function.

At 4 inches of projection, the Emtek 2231 baseboard door stop and the Sure-Loc 4 inch solid door stop both give you a quarter inch more clearance in the same baseboard-mounted format. For anything beyond that, or where you cannot get a solid anchor into the base, a floor-mounted bumper like the Delaney 2 inch round solid brass unit takes the load into the slab instead of the wall.

Yes, the 518 is offered in US26D, which is satin chrome. That is the most common commercial finish spec, so it lines up with satin chrome levers, closers, and hinges already on an institutional opening. The line is also offered in other standard architectural finishes.

The Rockwood 518 is a commercial door stop, cast brass with a rubber bumper, and Rockwood hardware is used on institutional buildings, offices, retail, educational, detention, sports facilities, hotels and restaurants. The Sure-Loc 3-1/8 inch and 3-3/4 inch spring stops are described as residential door stops. For school corridors, healthcare, or multi-family common areas where doors are thrown open repeatedly, the cast brass rigid body of the 518 is the specification-grade choice; the spring units suit lower-traffic residential doors.

No, they solve the problem at different points. The Rockwood 518 fastens to the baseboard with two #8 x 3/4 inch oval head sheet metal screws and stops the door against the wall. The Delaney 2 inch round solid brass floor bumper mounts to the floor and catches the door face before it reaches the wall. Use a floor bumper when the wall behind the door is glass, tile, or otherwise not suitable for fastening, or when the door swings past the end of the baseboard. Use the 518 when you want nothing on the walking surface.

The 518 has a 3-3/4 inch projection. For a tighter gap between baseboard and door, the Sure-Loc 3-1/8 inch spring door stop and the Orca Hardware 3-1/8 inch spring door stop are shorter units. Both are spring-bodied rather than rigid, so the door contact is cushioned by flex in the body instead of a fixed cast arm. Measure from the face of the baseboard to the point on the door the stop will meet, and pick the length that contacts the door before the lever or pull reaches the wall.

Two 4 inch options sit just above the 518's 3-3/4 inch projection. The Emtek 2231 is a 4 inch baseboard door stop, and the Sure-Loc DS7 is a 4 inch solid door stop. Both add roughly a quarter inch of reach over the 518, which matters when a thick baseboard or a chair rail pushes the mounting surface further off the wall line. If your projection requirement falls between sizes, the Delaney baseboard stop covers 3-1/2 to 4-1/2 inches adjustably.

The rubber bumper comes standard in white, with gray and black offered as options. On darker base trim or dark finished hardware, the gray or black bumper is what keeps the stop from reading as a white dot on the wall. The stop itself is offered in standard architectural finishes.
