Pamex DD02-20 3-1/8" Cast Door Stop

It's a wall-mounted stop, not a floor or hinge-pin type. The body is zinc die-cast with a 15/16 inch diameter base that sits flat against the wall or baseboard and takes a single fixed screw. Because it's a screw-in stop, it needs solid backing behind it: a stud, blocking, or a proper drywall anchor. Fastening into bare drywall with the 3-1/8 inch lever arm working against it is how these get pulled out of the wall.

Pamex rates the DD02-20 as a residential door stop. For single-family, condo, or in-unit apartment doors it's the right class of part. For a corridor, a stairwell, an entry that gets kicked open with a cart, or anything on a door closer, step up to a heavy duty commercial stop: the Ives WS11 and the Ives WS33 are both heavy duty wall stops with a replaceable rubber bumper, which is the part that wears out first in high traffic.

No. The DD02-20 stops the door and nothing more, there's no catch or hold-open in it. If you need the door parked open, for moving furniture, deliveries, or ventilation, use a wall holder: the Ives WS20 is a manual wall holder with a hinged strike, and the Ives WS40 is an automatic wall holder with a heavy duty bumper pad. A holder needs a strike plate on the door as well as the wall unit, so it's a two-part install rather than the single screw a plain stop takes.

Only if the wall is close enough behind the door. The Pamex DD02-20 projects 3-1/8 inches from the mounting surface, which carries the knob or lever clear of the wall on its own. A flat bumper such as the Delaney 2-1/4 inch concave wall bumper or the Emtek 2255 brass wall bumper with regular rosette sits nearly flush and only cushions where the door or knob already reaches the wall. Measure from the wall face to the point of contact on the swinging door: if the knob would hit before a flush bumper does, you need the projecting stop.

The Pamex DD02-20 is a single fixed 3-1/8 inch projection. When the door needs to reach further, the ABH RM Series and ABH RMS Series wall door stops are offered with multiple length options, so the projection can be matched to how far the knob or lever stands off the finished wall. Take the measurement from the wall surface to the furthest point on the door in the open position before choosing a length.

A rigid cast stop takes the impact on a fixed arm anchored to the wall, so the door stops where you put it and stays put. A spring stop absorbs the swing and flexes, which is more forgiving on a door that gets swung hard but gives you less precise stopping. Delaney sells both types in a 3 inch length, the 3 inch spring door stop and the 3 inch HD rigid door stop, if you want to compare the two approaches at nearly the same projection as the DD02-20's 3-1/8 inches.

The DD02-20 ships as a zinc die-cast stop with a fixed screw and a 15/16 inch base, which is a wood-screw-into-stud arrangement. For a CMU, brick, or plaster-over-block wall you'd need a masonry anchor rated for the wall, or a stop specified for it: the Ives WS11 and WS33 are both listed for drywall and masonry applications.

If the previous stop pulled through and left a torn hole, a new DD02-20 screwed into the same spot will pull out again, the 3-1/8 inch arm gives it too much leverage. Either shift the stop to hit a stud, or patch and back the wall first. To cover an existing hole, Delaney makes a 2-1/8 inch hole plate metal cover. Anywhere the wall itself has failed, a concave wall bumper that spreads the load, like Delaney's 2-1/4 inch unit, or a hinge-pin stop that takes the wall out of the equation entirely, is the better fix.

The DD02-20 is a single-projection part at 3-1/8 inches, there's no longer version of the same model. When a deep base trim, a chair rail, or a long lever pull needs more standoff, the ABH RM Series and RMS Series wall door stops both come in multiple length options, which is the usual route for a non-standard reach. Measure from the finished wall surface to the point the door or handle would otherwise strike, and order to that.

The DD02-20 is a rigid zinc die-cast stop with a 3-1/8 inch projection off the mounting surface, so it takes the door on a solid post. The Delaney 3 inch spring door stop uses a coiled spring body that flexes when the door strikes it, while the Delaney 3 inch HD rigid door stop is the rigid equivalent. Spring stops are typically baseboard mounted and absorb the swing through the spring; a rigid cast stop transfers it straight into the fastener and the substrate behind it, so the wall or base needs to be sound where it lands.

The DD02-20 is a one-piece zinc die-cast stop with a 15/16 inch diameter base and a 3-1/8 inch projection, replaced as a unit. The Ives WS11 and the Ives WS33/WS33X are heavy-duty wall stops built with a replaceable rubber bumper, so the strike face is a serviceable part. On an opening where the bumper takes daily impact and gets replaced on a maintenance cycle, that serviceability is the deciding difference; on a low-traffic residential door, the cast stop is changed out whole.

The Ives WS11 and the Ives WS20 are both specified for drywall and masonry applications, so a block or concrete corridor wall is within their intended mounting range. The Pamex DD02-20 mounts with a fixed screw and is a residential-rated zinc die-cast stop. On masonry, the anchor governs: the stop is only as good as what the fastener bites into, so confirm the anchor type suits the substrate before setting the projection.

The Pamex DD02-20 covers a fleet in one part number across 605 bright brass, 609 antique brass, 613 oil rubbed bronze, 619 satin nickel, 622 polished chrome and 625 matte black, all on the same 3-1/8 inch projection. Where a unit needs a decorative flush bumper rather than a projecting stop, the Emtek 2255 is a brass wall bumper with a regular rosette. Where a corridor or common area takes commercial traffic, the Ives WS33/WS33X is a heavy-duty wall door stop with a replaceable rubber bumper.

The body is zinc die-cast, finished in one of six plated or coated BHMA finishes. That's the standard construction for a residential wall stop and it takes the plated finishes cleanly. If you specifically want a solid brass body, the Emtek 2255 is a brass wall bumper with a regular rosette.
