Pamex DD02-57 2-1/2" Diameter Convex Wall Stop

The DD02-57 convex wall stop projects 1 inch from the mounting surface, with a 2-1/2 inch diameter base. That 1 inch is what keeps the lever or knob from reaching the drywall, so measure from the wall face to the back of your trim at full swing. If the knob sticks out more than an inch past the door face, you need a longer wall bumper or a floor stop instead.

It ships complete with a 1-1/4 inch screw and an expansion shield, so nothing else is needed for a drywall or masonry anchor point. One stop, one fastener set. Note the shield is what carries the load, so hit blocking or set the shield properly in the board; a stop pulled straight out of hollow drywall takes a chunk of wall with it.

A wall stop only works when the door swings into a wall within reach of the stop's 1 inch projection. Swing into an open room, a closet return, or a corner and there is nothing to anchor to. In that case use a base-mounted stop such as the Delaney 3 inch rigid door stop, or a spring stop like the Delaney 3 inch spring door stop that mounts to the door or baseboard and flexes on impact.

The DD02-57 stops the door, it does not hold it. It is a bumper only, brass with a 1 inch projection. If you need the door to stay open for carts, moving, 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 bumper pad. Those catch and retain the door instead of bouncing it back.

The DD02-57 is fixed at 1 inch of projection, so it will not clear a thick base or a door that stands proud of the wall. Where you need to bridge a longer gap, the ABH RM Series and ABH RMS Series wall door stops are offered in multiple lengths, which is the usual fix for deep trim or a door that swings past the wall plane.

The DD02-57 is a residential convex wall stop in brass with a 2-1/2 inch diameter base and 1 inch projection. For a commercial corridor taking constant traffic, the Ives WS11 heavy duty wall stop has a replaceable rubber bumper and is made for drywall and masonry, and the Ives WS33/WS33X is also a heavy-duty wall door stop with a replaceable rubber bumper. The replaceable bumper matters where the pad wears out and you would rather swap the pad than pull the anchor.

A wall stop like the Pamex DD02-57 projects 1 inch from the mounting surface and needs a wall directly behind the swing. Where there is no wall in reach, a floor or door-mounted stop does the job: the Delaney 3 inch HD rigid door stop and the Delaney 3 inch spring door stop both stop the door without a wall strike point.

No. The DD02-57 is a wall stop, so it stops the swing and lets the door close again. To hold the door open you need a wall holder: the Ives WS20 is a manual wall holder with a hinged strike for drywall and masonry, and the Ives WS40 is an automatic wall holder with a heavy duty bumper pad. The WS20 requires someone to engage the strike; the WS40 catches on contact.

Convex means the strike face bulges outward, so the knob or lever contacts a domed surface, that is the DD02-57 at 2-1/2 inches across. A concave bumper is dished, cupping a round knob so it seats rather than glances off, the Delaney 2-1/4 inch concave wall bumper is that style. Round knobs generally do better against a concave cup; levers and flat escutcheons hit a convex dome fine.

Six finishes: 605 bright brass, 613 oil rubbed bronze, 619 satin nickel, 622 matte black, 625 polished chrome, and 630 satin stainless steel. Those are standard BHMA finish codes, so if your existing knobs or hinges are marked 613 or 619, the stop will match the same code across brands closely. Base metal is brass under all six.

No. The Delaney 2-1/8 inch hole plate metal cover is a cover plate that conceals an opening in the surface; it does not absorb a door strike. The DD02-57 is a wall stop with a 2-1/2 inch base and a 1 inch projection that takes the impact of the door. The hole plate cover is the part to reach for when you have removed an old stop and need to close the hole it left, not when you need to stop the door.

The DD02-57 is a fixed convex stop with a 2-1/2 inch base and a 1 inch projection, shipped with a 1-1/4 inch screw and expansion shield. The ABH RM series and RMS series wall door stops are offered with multiple length options, so the projection is chosen to suit how far the wall sits from the door. Pick the ABH series when the gap is longer than a 1 inch projection can bridge.

Brass is the substrate on the DD02-57, which is why it does not rust the way a plated steel stop does in a bath or near salt air. In those spots the finish is what fails first, not the metal, so 630 satin stainless steel or 613 oil rubbed bronze will show water spotting and wear less than 625 polished chrome. If you want a brass wall bumper from another line, the Emtek 2255 brass wall bumper with regular rosette is the comparable.

Swing the door slowly to where you want it to stop and mark the wall at the center of the knob or lever. That mark is your anchor point for the DD02-57, since the stop's 1 inch projection plus the 2-1/2 inch base means the contact face sits an inch off the wall, centered on your mark. Drill for the expansion shield at that point and drive the 1-1/4 inch screw. Hitting the trim ring rather than the knob body is the usual mistake, so check at knob centerline height, not at the door edge.

They solve the problem at different ends of the door. The Pamex DD02-57 mounts to the wall and takes the strike at the wall surface with a 1 inch projection. The Delaney 3 inch spring door stop flexes at the base and mounts at the door or floor, while the Delaney 3 inch HD rigid door stop is fixed rather than sprung. If the baseboard or wall behind the door cannot take an anchor, the sprung and rigid door stops move the anchor point off the wall entirely.
