Pamex DD02-31 3-1/8" Heavy Duty Spring Door Stop

Projection is 3-1/8 inches from the mounting surface, so the knob or lever stops that far short of the wall. Measure from your wall to the point on the door that would strike first, usually the knob face, and if that gap is more than 3-1/8 inches the knob still hits before the stop does. In that case you want a longer stop rather than this one.

Pamex lists the DD02-31 as a residential product. It suits single family homes, condo interiors, and light apartment doors. For a commercial corridor, a school, or a high traffic entry, go to a heavy duty wall stop instead: the Ives WS11 and the Ives WS33/WS33X are both heavy duty wall stops with replaceable rubber bumpers, which matters when the bumper wears out under constant use rather than replacing the whole stop.

It ships complete with a 13/16 inch screw and a metal base measuring 15/16 inch in diameter. Into a wood stud that screw is all you need. Into hollow drywall with no stud behind it, the supplied screw will not hold a door swinging into it, so pick up a drywall anchor sized to a 13/16 inch screw or move the stop over to hit framing.

The DD02-31 only stops the door, it does not hold it. A spring stop cushions the swing and keeps the knob off the wall, then the door swings back freely. If you need the door to stay open, that is a wall holder, not a stop: the Ives WS20 is a manual wall holder with a hinged strike, and the Ives WS40 is an automatic wall holder. Those catch the door and keep it parked until released.

A spring stop gives when the door hits it; a rigid stop does not. The Pamex DD02-31 is a spring door stop that projects 3-1/8 inches from the mounting surface. The Delaney 3 inch HD Rigid Door Stop is the rigid counterpart at 3 inches. The spring version tolerates a door that arrives with some force and forgives a stop mounted slightly off the sweet spot; the rigid version holds a fixed stopping point and does not flex under the door. Choose by whether you want the door caught at an exact position or cushioned on arrival.

When the base shoe or chair rail pushes the contact point out past a standard stop, move to a series that offers length choices. The ABH RM Series wall door stops come in multiple length options, as do the ABH RMS Series wall door stops. The Pamex DD02-31 is fixed at 3-1/8 inches of projection from the mounting surface, so it is a single-length part. Measure from the finished wall face to where the door edge or knob actually lands, then pick the ABH length that meets it.

The Delaney 3 inch Spring Door Stop is the nearest match in form and function. Both are spring-style base-mounted door stops that flex on contact rather than standing rigid. The Pamex DD02-31 projects 3-1/8 inches from the mounting surface and is zinc die-cast; the Delaney unit is a 3 inch spring door stop, so the projection is a quarter inch shorter. If you are matching an existing stop across a set of doors, the projection difference is the number to check first, since it decides how far the door swings before it is caught.

Step up to a heavy duty wall stop. The Ives WS11 is a heavy duty wall stop with a replaceable rubber bumper for drywall and masonry, and the Ives WS33/WS33X is a heavy-duty wall door stop with a replaceable rubber bumper as well. The Pamex DD02-31 is a residential-rated spring stop in zinc die-cast. Where a spring stop absorbs the strike by flexing, the Ives units mount to the wall and take the hit on a bumper you can swap out when it wears, which is what a high-traffic corridor with repeat impacts is asking for.

A stop and a holder are not the same device. The Pamex DD02-31 is a spring door stop and releases the door as soon as you pull it back. If the door has to stand open, 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 is engaged by hand at the strike; the WS40 catches on contact. Both hold the leaf open, which a spring stop will not do.

Yes, the DD02-31 is built to ANSI/BHMA A156.16, the standard covering auxiliary hardware such as door stops and bumpers. That is the reference a spec writer or facility buyer will be looking for on a submittal, though note Pamex classes this particular stop as residential rather than commercial duty.

Six finishes, all by BHMA number so they cross-reference against your existing hardware: 605 bright brass, 609 antique brass, 613 oil rubbed bronze, 619 satin nickel, 622 matte black, and 625 polished chrome. If your levers or hinges carry one of those codes, order the stop in the same number and it will match. Property managers standardizing a building usually pick one code and buy across all doors.

The DD02-31 mounts on a 15/16 inch diameter metal base, so it covers a small pilot hole but not a torn out anchor hole much bigger than that. If the old stop pulled through and left a wide hole, set a hole plate behind the new stop: the Delaney 2-1/8 inch hole plate metal cover is made for exactly that, and its diameter is wide enough to sit behind the DD02-31 base.

The DD02-31 ships with a 13/16 inch screw intended for wood framing, not a masonry fastener. For block, brick, or concrete you would need to supply your own anchor. If the job is masonry throughout, the Ives WS11 and Ives WS33/WS33X wall stops are both listed for drywall and masonry applications and are the cleaner specification for that wall type.

A wall bumper does a different job. The Emtek 2255 is a brass wall bumper with a regular rosette and the Delaney 2-1/4 inch Concave Wall Bumper is a concave-face bumper; both mount on the wall and take the knob or lever, protecting the drywall at the point of contact. The Pamex DD02-31 projects 3-1/8 inches from its mounting surface as a spring stop that arrests the door itself. If the concern is a knob punching the wall, the bumper is the right part. If the door needs to be stopped short of the wall entirely, the spring stop is.

No. The Delaney 2-1/8 inch Hole Plate Metal Cover is a plate that conceals an opening in a surface. It does not arrest a door. The Pamex DD02-31 is a wall door stop with a 3-1/8 inch projection that catches the leaf. Order the hole plate only when you are pulling a stop or other hardware out and need to cover the hole it leaves behind, and order it in addition to a stop, not in place of one.

The Ives WS11 and the Ives WS33/WS33X are both heavy duty wall stops built with a replaceable rubber bumper, so the wear part comes off and a new one goes on with the base left in the wall. The Pamex DD02-31 is a zinc die-cast spring stop supplied complete with a 13/16 inch screw and metal base. For a property manager carrying spares across a large door count, the replaceable-bumper design changes what sits on the shelf: bumpers rather than whole stops.

Zinc die-cast body with a metal base. Zinc die-cast handles normal interior humidity fine, including a bathroom, and the plated finish is what carries the appearance. For a salt air exposure or anywhere the stop gets wet regularly, a solid brass unit is the tougher choice, and the Emtek 2255 brass wall bumper is one ZenSupply carries.

No handing. A wall stop mounts to the wall and takes the door on its face, so the same DD02-31 works on a left hand or right hand door. The only thing that changes is the height and horizontal position you set it at, which you take off where the knob or lever actually contacts.
