Deltana ZBDS30 3" Baseboard Door Bumper, Zinc Die-Cast

The ZBDS30 mounts on the baseboard and projects 5/8 inch at the tip, so it catches the door face 5/8 inch off the wall surface. That is enough to stop a door leaf, but it is not enough clearance for a lever or knob that swings past the door face and strikes the wall higher up. If the handle is what is punching the drywall, you want a floor-mounted bumper or a hinge-pin style stop instead of a baseboard bumper. Measure how far the knob stands proud of the door before you order.

The ZBDS30 is a bumper: it arrests the door swing and protects the wall, and it does not latch the door in the open position. If holding the door open is the requirement, the Orca Hardware TH-30HD is a rigid stop whose function is a door holder, and the Hager 212 is an adjustable rigid door stop with an 80 to 120 degree range, so the hold point can be set within that arc. Those are the parts to order for a door that has to stay open for carts, deliveries, or ventilation; the ZBDS30 covers the stop-only case.

The Deltana ZBDS30 is a fixed 3 inch baseboard bumper, so the reach is set the moment you pick the part. The Delaney solid brass baseboard door stop adjusts from 3-1/2 inch to 4-1/2 inch, which lets one part number cover openings where the gap between door and baseboard varies from unit to unit. On a multi-family or hotel turn where the door positions are not consistent, the adjustable Delaney is the safer order; where the openings are uniform and you want a solid one-piece stop, the ZBDS30 does the job.

A baseboard bumper like the Deltana ZBDS30 needs trim to fasten into, so it is the wrong part for a bare wall. Two alternatives mount elsewhere. The Delaney 2 inch round solid brass floor bumper anchors to the floor, which takes the door entirely off the wall surface. The Orca Hardware TH-3118 is a 3-1/8 inch spring door stop, and the TH-3134 is the same style at 3-3/4 inch; a spring stop mounts to the door or the base and flexes on contact. Pick the floor bumper when the flooring accepts an anchor, and a spring stop when it does not.

A baseboard bumper like the ZBDS30 fastens into the trim, so you drill wood instead of tile, hardwood, or a concrete slab, and nothing sticks up out of the floor to catch a vacuum or a toe. The trade-off is that it only works where the door swings into a wall with baseboard on it. If the door swings into open space, or the wall behind it is glass or a cabinet run, a floor bumper is the right call, and the Delaney 2 inch round solid brass floor bumper covers that. Where the door needs to be held open rather than just stopped, a door holder such as the Orca Hardware TH-30HD is the different tool for that job.

Zinc die-cast, finished in the plating you select. It is a residential-duty part, which is the right level for apartments, condos, and single-family turns. For a heavy-traffic commercial corridor or an entry that gets slammed, a solid brass baseboard stop like the Delaney adjustable 3-1/2 to 4-1/2 inch model gives you more mass behind the strike.

Seven finishes on the ZBDS30: polished brass, antique brass, oil rubbed bronze, brushed nickel, antique nickel, polished chrome, and brushed chrome. That covers both the warm and the cool sides of a typical Deltana trim package, so a property manager standardizing a building can pull one bumper finish across every unit and have it read with the levers and hinges already on the doors.

A spring stop, like the Orca Hardware TH-3118 at 3-1/8 inch or the TH-3134 at 3-3/4 inch, uses a flexible spring body that gives when the door strikes it. The Deltana ZBDS30 is a rigid 3 inch zinc die-cast baseboard bumper with a 5/8 inch tip projection, so the door stops where the tip sits. They are close in overall length, which is why they get swapped for one another, but the behavior at the door differs: the spring absorbs the swing over its travel, while the baseboard bumper arrests it at a fixed point.

The Deltana ZBDS30 is a zinc die-cast baseboard bumper listed for residential use, which suits apartment interiors, offices, and unit doors. For a corridor door taking constant traffic, the rigid stops in the set are the heavier answer: the Orca Hardware TH-30HD is a heavy-duty rigid door stop that also functions as a holder, and the Hager 212 is an adjustable rigid door stop with an 80 to 120 degree range. Rigid stops take the load through a solid arm rather than a bumper tip, which is the usual spec for a door that gets pushed hard many times a day.

The ZBDS30 is zinc die-cast, offered in finishes including Polished Brass and Antique Brass, so the brass appearance comes from the finish rather than the base metal. If the spec calls for solid brass on the substrate itself, the Delaney adjustable 3-1/2 inch to 4-1/2 inch baseboard door stop and the Delaney 2 inch round floor bumper are both solid brass. This is the distinction to check before matching an existing installation, because the two look alike on the wall but are not the same material.

One bumper. The ZBDS30 sells by the each, packed in an individual poly bag, so a contractor doing a 40-door turn orders 40. There is no pair or box quantity to work around.

The Deltana ZBDS30 is 3 inches. Of the spring stops, the Orca Hardware TH-3118 at 3-1/8 inch is the nearer match, with the TH-3134 running 3-3/4 inch for a door that needs to be held farther off the wall. If you are replacing ZBDS30 bumpers on some doors and using spring stops on others in the same building, the TH-3118 keeps the standoff distances closest to consistent across the openings.
