Rockwood 508 4-3/16" Screw In Door Stop

The Rockwood 508 is a fixed baseboard stop with a 4-13/16 inch projection, so the door is halted that far off the face of the baseboard. Measure from the baseboard to the tip of your lever or push plate with the door swung open: if that projection is under 4-13/16 inches, the 508 catches the door first and the trim never touches the wall. It is a fixed reach, not adjustable, so on an opening where you need to dial it in, Delaney's solid brass baseboard door stop adjusts from 3-1/2 to 4-1/2 inches instead.

Mounting is by a #10-24 x 1-1/4 inch hanger bolt. A hanger bolt is threaded both ways, wood-screw threads on one end that drive into the baseboard and #10-24 machine threads on the other that the cast brass stop body turns onto, which is why the finished install shows no exposed screw head. You need 1-1/4 inches of solid wood behind the mounting point for the wood end to bite, and the stop has to land where the door edge or the door face actually swings to.

No. The 508 anchors with a #10-24 x 1-1/4 inch hanger bolt, and the wood-thread end of that fastener needs solid wood, so drywall alone or a hollow partition will not hold it and the stop will pull out the first time a door is thrown open. Either add solid blocking behind the finish surface at the strike point, or switch to a floor-mounted stop. Delaney's 2 inch round solid brass floor bumper anchors into the floor instead of the wall, and Orca's 3-1/8 inch and 3-3/4 inch spring door stops are the other common route when the wall cannot take the load.

Stop only. The 508 is a rigid baseboard stop with a rubber bumper that halts the swing and cushions the impact, and nothing on it latches or catches the door in the open position. If the requirement is holding a door open for deliveries or airflow, you want a holder instead: Orca Hardware's TH-30HD is catalogued as a door holder, and Hager's 212 is an adjustable rigid door stop with an 80 to 120 degree range.

The Rockwood 508 is a cast brass screw in stop with a rubber bumper that projects 4-13/16 inches off the baseboard and anchors with a #10 - 24 x 1-1/4 inch hanger bolt. The Emtek 2231 is a baseboard door stop at 4 inches, which sets the door back at a similar point in the swing. The Delaney 40201X is a solid brass baseboard door stop adjustable from 3-1/2 to 4-1/2 inches, covering a spread of trim depths from one part number. All three take the door at the baseboard rather than at the floor, so the mounting surface and the strike point on the door face stay the same when you move between them.

The Rockwood 508 is built to a fixed 4-13/16 inch projection, which suits a building where every opening carries the same trim. Where the trim depth changes door to door, the Delaney 40201X is a solid brass baseboard door stop that adjusts from 3-1/2 to 4-1/2 inches, so a single part number takes up the variation at install. The Emtek 2231 is a fixed 4 inch baseboard door stop, another fixed projection option if the openings are consistent. Measure from the baseboard face to where the door face lands at the open position before choosing between fixed and adjustable.

The Rockwood 508 arrests the door on a rubber bumper and lets it swing back closed, which is what a baseboard stop does. If the door has to remain at the open position, the Orca Hardware TH-30HD is a heavy duty rigid door stop whose function is a door holder, so it keeps the leaf where it is put rather than only cushioning the impact. The two do different jobs at the opening: order the 508 for a protected wall and a free swinging door, and the TH-30HD where a loading door or a propped corridor door needs to stand open on its own.

It carries ANSI A156.16, type number L02031, which is the standard covering auxiliary hardware including stops and bumpers. Give the specifier the model number 508 with the L02031 type and the 626 finish and it lines up with a schedule written that way. It is a commercial-duty product, cast brass rather than a stamped or plated zinc part, so it is the right class of stop for institutional and MRO standardization across a building.

It comes in 626, satin chrome, which is the same finish designation used across commercial levers, closers and exit device trim, so it reads consistently against 626 hardware already hanging in the building. The base metal is brass with a cast brass body, so the finish is applied to solid brass rather than to a plated pot-metal shell.

A baseboard stop such as the 508 mounts to the wall base and takes the door on its face, keeping the floor clear of anything to trip over or vacuum around, and it puts the load into the baseboard and the framing behind it. A floor stop, like Delaney's 2 inch round brass floor bumper, anchors into the slab or subfloor and works where there is no baseboard to bite into, but it sits in the walking path. Spring stops, such as the Orca 3-1/8 inch and 3-3/4 inch, flex on impact rather than stopping the door dead. On carpeted commercial corridors and hotel guest rooms the baseboard version is usually the cleaner install; in tile or where the wall cannot be drilled, the floor type wins.

For a like-for-like brass baseboard stop, Emtek's 2231 is a 4 inch baseboard door stop and Delaney's solid brass baseboard stop covers 3-1/2 to 4-1/2 inches adjustable, which is the one to reach for when the projection you need is not settled. Neither is a straight swap for the 508's 4-13/16 inch reach, so check the projection against your opening before switching. What is not a substitute is the Orca TH-30HD: that is a door holder, a different function entirely.

The Rockwood 508 is a baseboard stop fastened with a #10 - 24 x 1-1/4 inch hanger bolt, so it wants solid baseboard or blocking behind the anchor point. Where that backing is not there, the Delaney 4029XX is a round solid brass floor bumper standing 2 inches high, which anchors in the floor inside the door arc and takes the door at the bottom rail instead of at the face. That moves the fastening from the wall to the floor, so the decision is really about which surface you can anchor into and whether a 2 inch obstruction in the floor path is acceptable in that space.

They stop a door, but they are not a like for like swap. The Orca Hardware TH-3118 is a 3-1/8 inch spring door stop and the TH-3134 is a 3-3/4 inch spring door stop, both spring stops that flex as the door meets them. The Rockwood 508 is a rigid cast brass screw in baseboard stop with a rubber bumper, projecting 4-13/16 inches and anchored with a #10 - 24 x 1-1/4 inch hanger bolt. The spring stops absorb the swing through the spring body at a shorter reach, while the 508 holds the door off the wall on a solid brass body at a longer fixed projection, so the reach off the wall and the way the impact is taken both change when you move between them.

The Hager 212 is an adjustable rigid door stop with an 80 to 120 degree range, so the point at which the door is arrested is set by degrees of swing. The Rockwood 508 is a cast brass baseboard stop with a 4-13/16 inch projection, where the door comes to rest when the bumper meets the door face, so the stopping point follows the geometry of the wall and the trim. Pick by which constraint governs the opening: a set angle of swing points to the 212, and a set clearance between door face and baseboard points to the 508.

The rubber bumper ships white as standard, with gray and black offered as options. That matters more than it sounds on a dark-stained or painted base, where a white bumper is the one part of the install anyone notices. Specify the bumper color when you order, since the finish code covers the brass body only.

It is built as commercial hardware, not residential: a cast brass body with a rubber bumper, mounted on a #10-24 x 1-1/4 inch hanger bolt, and meeting ANSI A156.16 under type L02031. Rockwood hardware of this kind goes into institutional buildings, offices, retail, schools, detention, sports facilities and hotels. The weak point in a heavy traffic install is almost never the stop itself, it is the backing: get the hanger bolt into solid wood and the brass body will outlast the baseboard it is screwed to.

Length is the difference. The Orca Hardware TH-3118 is a 3-1/8 inch spring door stop and the TH-3134 is a 3-3/4 inch spring door stop, both carrying a door stop function, so the longer body holds the door face farther off the wall. Measure the clearance you need between the open door and whatever is behind it: hardware standing proud of the door face, a lever, or a pull can decide it. Where the opening needs more reach than either, the Rockwood 508 is a cast brass baseboard stop at a 4-13/16 inch projection.
