Yes. The 485AA head and jamb gasketing is fire-rated to UL10C, and it also carries smoke and draft control testing, so it can go on a labeled opening where the door assembly calls for smoke and draft seals. It is also air infiltration tested and sound tested, and it meets ANSI/BHMA R3B164.

Three set sizes, all 84 inches on the jamb legs: 36 x 84, 48 x 84, and 72 x 84 inches. The 36 and 48 inch head pieces cover single doors of those widths; the 72 x 84 set is the one to order for a pair of doors. The extrusions are supplied full length and field-cut to size, so if your opening is under the nominal size you trim to fit on site.

One 485AA set covers the perimeter: the head piece plus both jamb legs. It seals the top and sides only. The bottom of the door is a separate item, so if you also need the sill sealed you are ordering a door sweep, door shoe or automatic door bottom on top of this.

Neoprene bulb and finger, like the 485AA, is the choice when you need a compression seal that stops air and smoke and holds a sound rating. A nylon brush seal such as the NGP 602A wipes rather than compresses, so it suits high-traffic or sliding applications where drag and wear matter more than a tight seal. A magnetic seal like the NGP 159MA pulls tight against a steel door face and is used where you want acoustic contact without constant compression drag on the closer. If you want the same compression style in vinyl instead of neoprene, the NGP 155V and Cal-Royal PG-601 are aluminum channel perimeter seals with vinyl inserts.

The Zero 485AA is an aluminum head and jamb perimeter set with a solid neoprene seal in a clear anodized aluminum finish. The nearest peer is the NGP 108NA, a neoprene sponge seal in an anodized aluminum frame rated for a temperature range of -20 F to 200 F. Both put a neoprene sealing element in an anodized aluminum carrier mounted to the head and jambs. The 485AA seal is solid neoprene with an extruded bulb/finger for double-sealing; the 108NA uses a sponge neoprene element. Cal-Royal's PG-601 is also an aluminum channel perimeter gasketing, but its sealing element is a vinyl insert rather than neoprene.

The Zero 485AA is fire rated UL10c, rated for smoke and draft control, air infiltration tested, sound tested, and certified ANSI/BHMA R3B164. The comparable perimeter seals are identified by their sealing element and housing - the NGP 108NA as a neoprene sponge seal in an anodized aluminum frame, the NGP 155V as a vinyl perimeter seal in a mill aluminum frame, the NGP 602A as a nylon brush seal, and the Cal-Royal PG-601 as an aluminum channel gasketing with a vinyl insert. On a rated opening in a healthcare, education or government facility, the listing on the specific gasket is what the inspector checks, so verify the certification on any part before it goes on a fire door rather than assuming a like-for-like profile carries it.

A compression seal like the Zero 485AA relies on the door closing against a solid neoprene bulb, which adds closing resistance on an opening that is already tight or out of square. Where compression is not workable, the NGP 602A is a nylon brush seal in an anodized aluminum housing: the brush filaments sweep the door face instead of compressing against it, so the door swings with much less resistance. That trade goes the other way on performance - the 485AA is sound tested and rated for smoke and draft control, and a brush seal is a different class of sealing. For a door that needs a firm seal without a wide compression set, the NGP 159MA magnetic seal in an 84 inch anodized aluminum frame pulls closed against the frame magnetically rather than by door pressure alone.

No - they seal different edges of the opening. The Zero 485AA is a head and jamb gasketing set, so it addresses the top and the two sides of the door. The Cal-Royal PG-601 is aluminum channel perimeter gasketing with a vinyl insert that sits in the Door Shoes Series, and a door shoe seals the bottom edge against the threshold. On a full exterior opening a contractor typically needs both: perimeter gasketing at the head and jambs plus a bottom seal. Ordering one when the drawing called for the other leaves an unsealed edge.

Both. The 485AA uses an extruded bulb and finger profile in solid neoprene, which gives you two lines of contact against the door face rather than one. That double contact is why it is sound rated for acoustic door assemblies, where a single-contact seal usually is not enough.

AA is the finish code for clear anodized aluminum, which is the housing finish on every 485AA set. The anodized aluminum retainer is the part that screws to the frame; the neoprene is what seals against the door.

Functionally yes, they all seal the same way, but the housings will not look identical. If matching appearance across a building matters, note the 485AA housing is clear anodized aluminum; the NGP 108NA is also a neoprene seal in an anodized aluminum frame, while the NGP 155V uses a mill aluminum frame, which is a different look. For a fire-rated or smoke-rated opening, stay with the 485AA, since UL10C and smoke and draft control are stated for it.

Yes, it is sound tested and rated for use on acoustic door systems. The double contact from the bulb and finger profile is what does the work. Bear in mind that perimeter gasketing only handles the head and jambs, so the sound path under the door remains open until you add a bottom seal.

The Zero 485AA is sound tested and uses an extruded bulb/finger for double-sealing, which is why it turns up on acoustic door systems. Among the alternatives, the NGP 159MA magnetic seal in an 84 inch anodized aluminum frame is the other one built for a positive continuous seal at the head and jambs - a magnetic element closes the gap along the full frame without depending on the door being pulled tight. The NGP 602A nylon brush seal and the NGP 155V vinyl perimeter seal are perimeter gasketing of a different type; a brush seal in particular leaves filament gaps rather than a continuous compressed face. If the drawing calls for the 485AA on an acoustic opening, match it on the neoprene compression seal, not on the fact that a part mounts in the same channel.

The Zero 485AA is supplied in a clear anodized aluminum finish, in 36 inch, 48 inch and 72 inch widths by 84 inch. The NGP 108NA neoprene sponge seal and the NGP 602A nylon brush seal both use anodized aluminum housings, and the NGP 159MA magnetic seal is an 84 inch anodized aluminum unit, so all three will read as the same metal alongside existing anodized frames. The NGP 155V uses a mill aluminum frame, which is untreated and will not match a run of anodized stops. For a property manager standardizing a corridor or a stairwell run, that finish call is what keeps the openings looking like one set.

The Zero 485AA uses a solid neoprene seal in an aluminum carrier and is air infiltration tested, which is the reason it gets used on exterior and demanding openings. Where the temperature swing is the deciding factor, the NGP 108NA neoprene sponge seal states a temperature range of -20 F to 200 F on an anodized aluminum frame. The NGP 155V is a vinyl perimeter seal, and vinyl and neoprene behave differently as compounds in heat and cold. For an MRO buyer standardizing across conditioned and unconditioned openings in the same facility, that compound choice is the one to settle first.

The Zero 485AA is supplied full-length and field-cut to size, in 36 inch, 48 inch and 72 inch widths by 84 inch, so an installer trims the aluminum carrier and neoprene to the opening rather than ordering a made-to-size piece. Among the alternatives, the NGP 159MA magnetic seal is specified at 84 inches, so it is sized to that height as supplied. If the frame is over-height, plan the run from full-length stock and cut it, which is how the 485AA is intended to be installed, and confirm the head piece and each jamb piece separately - the three legs of a perimeter set are rarely the same length.

The 485AA is a commercial-rated product, built for the traffic and the code requirements of commercial openings, and the housings mount to a hollow metal or commercial wood frame. It will physically work on a residential door with a suitable frame, but you are paying for fire, smoke and acoustic performance that a house door rarely needs.

It is air infiltration tested, and the solid neoprene bulb and finger compress against the door face to close the head and jamb gap. On an exterior opening you will still want the sill and bottom addressed separately, since that is usually where most of the measurable leakage on a door is.

The Zero 485AA uses an extruded bulb/finger in solid neoprene, which compresses against the door face for a continuous double seal and is sound tested and rated for smoke and draft control. The NGP 602A is a nylon brush seal in an anodized aluminum housing, where filaments sweep the door rather than compress against it. A brush tolerates a door that shifts, warps slightly or swings frequently without the drag a compression bulb creates, and it does not take a set over time the way a compressed elastomer can. A neoprene bulb closes the gap more completely. Both mount to the head and jambs of the frame, so the choice comes down to what the opening needs, not to how it installs.
