NGP 158VDKB – Frequently Asked Questions

1) Will the NGP 158VDKB astragal work on a pair of doors with beveled edges?
Yes. The 158VDKB overlapping astragal is made for beveled edge doors, so the seal lines up and closes properly against the edge instead of standing off it. It mounts on one leaf of a pair and overlaps the inactive leaf, closing the meeting stile gap with a PVC seal.
2) I need an astragal that works around a mortise lock on a pair of doors. Is this the right one?
No. The 158VDKB is a full-height weatherseal astragal with a vinyl bulb, meant to close the gap between leaves, not to clear lock hardware. For a pair with locks in the meeting stile, look at the Trimco 5001 stainless lock astragal, which is made for mortise or cylindrical locks, or the Trimco 5002 at 1-9/16 by 6 inches for cylindrical locks.
3) What is the difference between an overlapping astragal and a split astragal for a pair of doors?
The NGP 158V overlapping astragal is a single one-piece section that mounts to one leaf of the pair and laps over the meeting edge of the other, carrying a PVC vinyl seal that closes the gap between the two doors. A split astragal such as the Pemko 369 works differently: it is a two-piece arrangement with a pile brush insert, applied so each leaf carries its own half at the meeting stile. Choose the overlapping style when one leaf is the inactive leaf and can carry the full lapping section; choose a split type when both leaves need to open independently without an overlap projecting past the meeting edge.
4) Is there an astragal for a pair of doors that uses a brush seal instead of a vinyl seal?
Yes. The NGP 158V carries a thermoplastic PVC seal with a bio-based plasticizer, which is a flexible vinyl wiper against the mating leaf. If a brush seal is preferred, the Pemko 300 Series adjustable astragal uses a self-adjusting pile brush for double doors, and the Pemko 369 split astragal seal also uses a pile brush insert. Vinyl gives a continuous wiping contact; pile brush tolerates a less consistent gap between the two leaves, which is why the Pemko 300 Series is described as self-adjusting.
5) Which astragal should be used on a fire-rated pair of doors?
The Pemko 369 split astragal seal is identified as fire-rated, in a 13/32 inch by 11/32 inch aluminum profile with a pile brush insert. The NGP 158V overlapping astragal is an aluminum alloy 6063 T5 section with a PVC seal that carries a flame-resistant bio-based plasticizer formulation. Where a labeled opening requires a fire-rated gasketing product, specify the product carrying that rating and confirm it against the door and frame label.
6) Will a lock astragal work as a substitute for a full-height overlapping astragal?
No, they solve different problems. The Trimco 5001 and 5002 are lock astragals in stainless steel, and the 5002 measures 1-9/16 inch by 6 inch, meant for use with mortise or cylindrical locks. Those are short guard pieces at the lock area of the meeting edge, not a continuous weatherseal. The NGP 158V is supplied at 84 inch length with capability up to 120 inch, running the full height of the leaf with a PVC seal to weatherproof the pair. If the requirement is sealing air and moisture along the meeting stile, a 6 inch lock astragal does not do that job.
7) Does the NGP overlapping astragal come with mounting screws or do I need to buy fasteners separately?
Screws are in the box. It ships with #8 x 1 inch flat head undercut sheet metal screws, which is what you want for a hollow metal or metal-edged door leaf. Nothing else is required to hang it beyond a drill and driver.
8) Will an aluminum vinyl astragal hold up on an exterior door in cold winters?
The 158VDKB is rated from 0 F to 140 F, so it covers most North American exterior service but is not a deep sub-zero part. The extrusion is 6063 aluminum in T5 temper, which resists corrosion outdoors, and the dark bronze finish adds a protective coat.
9) Is the NGP 158VDKB astragal a vinyl seal or a brush seal, and which seals better against wind and dust?
It uses a thermoplastic PVC bulb seal, formulated with a bio-based plasticizer, with flame and moisture resistance. A vinyl bulb compresses to a continuous contact line, so it handles air and water infiltration better than brush. Brush types, like the Pemko 300 Series self-adjusting pile brush astragal or the Pemko 369 with pile insert, tolerate misaligned or warped leaves better because the pile takes up an uneven gap.
10) What is an aluminum T-astragal and how does it compare to the NGP 158V?
The Cal-Royal EAST-501 is an aluminum T-astragal with a vinyl insert for double doors: the T profile seats into the meeting edge with the flange projecting across the gap. The NGP 158V is an overlapping profile in aluminum alloy 6063 with T5 temper, also carrying a vinyl seal, designed to fit beveled edge doors and supplied with #8 x 1 inch flat head undercut sheet metal screws. Both close the gap at a pair with a vinyl element; the difference is the profile shape and how it sits relative to the door edge, so match the profile to the edge condition of the leaves you have.
11) What is the difference between the Trimco 5001 and 5002 lock astragals?
Both are Trimco stainless steel lock astragals for the meeting edge of a pair. The 5001 is specified for use with mortise or cylindrical locks, while the 5002 is specified for use with cylindrical locks and is stated at 1-9/16 inch by 6 inch. Select by the lock type prepped into the leaf.
12) Which double door astragal is best when the gap between the leaves is inconsistent?
An adjustable or brush type handles gap variation better. The Pemko 300 Series is an adjustable astragal with a self-adjusting pile brush for double doors, so the brush takes up variation across the height of the meeting edge. The NGP 158V overlapping astragal uses a fixed PVC vinyl seal on an aluminum 6063 T5 extrusion designed for beveled edge doors, which seals well where the leaves close to a consistent, true edge. On an older pair that has racked or where the leaves do not meet evenly, the self-adjusting brush design is the more forgiving choice.
13) Will a dark bronze astragal match the rest of my door hardware, and is bronze the only option on the NGP 158VDKB?
Dark bronze is the only finish the 158VDKB is offered in, and it pairs with the standard dark bronze anodized aluminum entrances and bronze-finish exit and pull hardware common on commercial storefronts. If your openings are clear anodized or mill finish, this one will read as a dark stripe down the meeting stile.
14) Is this astragal suitable for a commercial building, or is it a residential product?
The 158VDKB is a commercial-rated part. It is specified on office buildings, schools, healthcare, retail, warehouse, multi-tenant residential, and government facilities, and the 6063-T5 extrusion with a PVC bulb is the standard build for that service.
15) Is a stainless steel astragal available instead of aluminum for a high-traffic entry?
The Trimco 5001 and 5002 lock astragals are stainless steel, but they are short lock-area pieces rather than full-height weatherseals. The NGP 158V is aluminum alloy 6063 with T5 temper in a dark bronze finish, running 84 inch and up to 120 inch maximum height with a PVC seal rated for 0 F to 140 F. For a facility standardizing on a full-height sealed pair, the aluminum overlapping astragal is the weatherseal; a stainless lock astragal can be added separately at the lock for edge protection.
