NGP 158NA-84 – Frequently Asked Questions

1) Will the NGP 158NA astragal work on a beveled edge door?
That's exactly what the 158NA is built for. It's an overlapping astragal made to fit beveled edge doors, so the overlap sits correctly against the mating leaf instead of standing off the bevel. On a square edge door the overlap geometry won't seat the same way, so check the edge prep first.
2) Is the NGP 158NA astragal any good for a freezer door or a hot mechanical room?
Temperature range on the seal runs -80 F to 275 F. The seal is Thermo-Plastic Vulcanizate, which holds memory and abrasion resistance across that band, and it's BHMA certified to ANSI/BHMA A156.22 for the heat and cold performance tests. That covers cold storage vestibules and hot equipment rooms alike.
3) What is the difference between an overlapping astragal and a T-astragal or split astragal for double doors?
An overlapping type like the 158NA mounts on one leaf and laps over the other, so the active leaf has to close second. A T-astragal such as the Cal-Royal EAST-501, aluminum with a vinyl insert, sets between the leaves. A split astragal like the Pemko 369 puts a piece on each leaf, 13/32 x 11/32 inch aluminum with a pile brush insert, which lets either leaf swing free. Pick by how the pair operates before you pick by seal material.
4) What is the difference between an NGP 158NA overlapping astragal and a Trimco 5001 lock astragal?
They solve different problems on a pair of doors. The NGP 158NA is a full-height overlapping astragal with an integrated TPV seal, running the length of the door edge and supplied for doors up to 120 inches, in 84 inch and 96 inch lengths. The Trimco 5001 is a lock astragal in stainless steel, a short piece intended for use with mortise or cylindrical locks that covers the gap at the lock area rather than sealing the full meeting edge. If the goal is weather and light sealing along the whole meeting stile, the full-length overlapping type is the form to specify; if the goal is covering the latch area against a pry attempt, the short lock astragal is the form.
5) What astragal should be used on a fire-rated pair of doors instead of the NGP 158NA?
The Pemko 369 split astragal seal is a fire-rated aluminum astragal with a pile brush insert, 13/32 inch by 11/32 inch, and its product function is gasketing. A split astragal mounts a half on each leaf, so both doors can be opened independently, which is often what a fire-rated pair with two active leaves needs. The NGP 158NA is an overlapping type that carries a TPV seal certified to ANSI/BHMA A156.22 for heat and cold performance, mounted to a single leaf so it laps the other.
6) Is a brush-seal astragal an alternative to the NGP 158NA on a double door?
It is, with a different seal medium. The Pemko 300 Series is an adjustable astragal with a self-adjusting pile brush for double doors, and the Pemko 369 split astragal carries a pile brush insert. Both close the meeting-stile gap with brush rather than an elastomer. The NGP 158NA uses a TPV seal rated from -80 F to 275 F with resistance to ozone, sunlight and aging, and is built on 6063-T5 aluminum with an anodized finish. Brush handles doors whose meeting edges do not align consistently; a TPV seal is the choice where the opening sees weather and temperature extremes.
7) Does an overlapping astragal like the NGP 158NA need a mullion, or does it seal the pair by itself?
An overlapping astragal seals the meeting stile of a pair on its own, no mullion involved. The 158NA mounts to one leaf and laps the other, closing the gap between the two doors with its TPV seal. If you need the pair to be a secured opening rather than a sealed one, that's a device-and-mullion decision, not an astragal one.
8) Do I need to order fasteners separately for the NGP 158NA astragal?
Fasteners are in the box. The 158NA ships with #8 x 1 inch flat head undercut sheet metal screws. You'll want a drill and countersink for the leaf you're mounting to, but nothing else has to be added to the order to hang it.
9) What is the NGP 158NA astragal made of, and will it hold up on an exterior opening?
Aluminum alloy 6063 with T5 temper, anodized. The TPV seal is flame resistant and moisture resistant with good resistance to ozone, sunlight and aging, which is what matters on a weather-exposed pair. Anodized aluminum is the standard exterior astragal material for that reason.
10) The gap between my double doors is inconsistent. Is a fixed astragal like the NGP 158NA the wrong call?
On a pair with a gap that varies top to bottom, a fixed overlapping extrusion seals unevenly. The Pemko 300 Series is an adjustable astragal with a self-adjusting pile brush for double doors, which takes up that variation. Choose the 158NA where the gap is consistent and you want a TPV compression seal rather than brush.
11) What is the difference between the Trimco 5001 and Trimco 5002 lock astragals?
The Trimco 5001 lock astragal in stainless steel is specified for use with mortise or cylindrical locks. The Trimco 5002, also stainless steel, measures 1-9/16 inches by 6 inches and is specified for use with cylindrical locks. Confirm which lock body is in the door before ordering, since the 5002 is the narrower cylindrical-only piece.
12) If the meeting edges on my double doors do not line up well, is there a better astragal than the NGP 158NA?
The Pemko 300 Series is an adjustable astragal with a self-adjusting pile brush for double doors, and the adjustment is what accommodates leaves that hang out of alignment or drift with the seasons. The NGP 158NA is a fixed overlapping profile in 6063-T5 anodized aluminum designed for beveled edge doors, so it depends on the meeting edges being consistent to seal along their whole length. On an opening with settled or racked leaves, the adjustable brush type keeps contact where a fixed profile would show gaps.
13) What is the difference between a vinyl insert astragal and the TPV seal on the NGP 158NA?
The Cal-Royal EAST-501 aluminum T-astragal carries a vinyl insert. The NGP 158NA uses a Thermo-Plastic Vulcanizate seal, BHMA certified to ANSI/BHMA A156.22 for heat and cold, with a service range of -80 F to 275 F and good resistance to ozone, sunlight and aging, plus abrasion resistance and memory for consistent closure. On an interior or sheltered opening the insert type does the job; on a sun-exposed or extreme-temperature exterior, the certified TPV seal is the one to specify.
14) Is the NGP 158NA astragal rated for commercial use in a school or hospital?
It's specified as a commercial product, and the seal carries BHMA certification to ANSI/BHMA A156.22. NGP lists educational, healthcare, government, industrial and multi-tenant residential among its applications. For a fire door assembly, confirm the opening's listing separately, since the 158NA's stated certification is the A156.22 gasketing performance standard.
