NGP 125NSS 84 SET – Frequently Asked Questions

1) Is the NGP 125NSS astragal certified to any standard?
BHMA certified to ANSI/BHMA A156.22, tested for heat, cold and energy performance. That is the gasketing and edge seal standard, and it is what a spec writer or an inspector on a healthcare or school project will be looking for on the submittal.
2) Should I use a stainless smoke-rated astragal or an aluminum one with a brush seal?
Pick by what the opening has to do. The 125NSS is a stainless steel smoke-rated astragal with an EPDM compression seal, so it is what you want when the pair is a smoke barrier or an abuse-prone opening. If the job is dust, light and draft control rather than smoke, an aluminum astragal with a pile brush insert like the Pemko 300 Series self-adjusting brush astragal, or the Pemko 369 split astragal, is the lighter and simpler answer. The Cal-Royal EAST-501 is an aluminum T-astragal with a vinyl insert for double doors, another option where stainless is not required.
3) I need an astragal that works around a lock on the inactive leaf. Is the NGP 125NSS the right one?
No. The 125NSS is a full-height sealing astragal, not a lock astragal. If you are covering the gap at a mortise or cylindrical lock on a pair, look at the Trimco 5001 lock astragal in stainless steel, which is made for use with mortise or cylindrical locks, or the Trimco 5002 lock astragal in stainless, 1-9/16 by 6 inches, for cylindrical locks. Those are short pieces that address the lock area; the NGP set seals the full meeting stile.
4) What is the difference between the NGP 125NSS astragal and a Trimco 5001 lock astragal?
They solve different problems on a double door. The NGP 125NSS is a stainless steel smoke-rated astragal set with an EPDM seal that runs the full 84 inch height of the meeting stile, BHMA certified to ANSI/BHMA A156.22 for heat, cold and energy performance. The Trimco 5001 is a lock astragal in stainless steel, intended for use with mortise or cylindrical locks - a short piece at the lock area rather than a full-height sealing member. If the goal is smoke containment along the whole meeting edge, the 125NSS is the one that does it; if the goal is covering the gap at the lock on a pair, the 5001 addresses that.
5) What should I use if the two leaves of my pair do not close in perfect alignment?
The Pemko 300 Series is an adjustable astragal with a self-adjusting pile brush for double doors, which is the response to a meeting stile whose gap varies. The NGP 125NSS handles alignment differently: it is furnished as a two-piece set with slotted screw holes so the pieces can be positioned precisely at install, with #6 x 3/4 inch stainless SMS fasteners furnished. The difference is where the adjustment lives - the Pemko 300 adjusts as the doors move, the 125NSS is set once at mounting and then compresses through its EPDM seal.
6) What temperature range will the EPDM seal on the 125NSS hold up to?
Rated from -81 F to 275 F. That covers unconditioned warehouse and industrial openings, exterior doors in hard winters, and mechanical or boiler room doors where the ambient runs hot. The seal material is a synthetic EPDM rubber in a polypropylene thermoplastic closed cell foam matrix, and it is flame resistant and moisture resistant with good resistance to ozone, sunlight and aging.
7) Do I need to buy screws to install the NGP 125NSS astragal?
No, fasteners come with the set. #6 x 3/4 inch stainless steel sheet metal screws are furnished, and the mounting holes are slotted so you can shift the piece for alignment before you drive them home. That slot matters on a pair that is not perfectly hung, since you can dial in seal contact instead of living with where the first screw lands.
8) What finish is the NGP 125NSS stainless astragal, and will it match my other door hardware?
Brushed #4 stainless, which is US32D / 630. That is the same satin stainless designation used on commercial exit devices, push plates and pulls, so it lines up with the standard satin stainless package on most commercial openings. If your building is standardized on satin chrome (US26D), the two read very close side by side but are not the same finish family.
9) Is the NGP 125NSS astragal suitable for a fire-rated door assembly?
It is listed by the manufacturer for fire-rated door assemblies along with commercial office, healthcare, education, government, industrial and multi-tenant residential openings. The seal material is flame resistant, and the set is BHMA certified to ANSI/BHMA A156.22. For a labeled opening, the assembly listing governs what may be applied, so match the astragal to what the door and frame label allows.
10) Does one NGP 125NSS 84 SET cover a whole pair of doors, or do I need two?
One set covers one pair. The 125NSS 84 SET is supplied as a two-piece set, one piece per leaf, at 84 inches each. Order one set per double door opening, not one per leaf.
11) I need a fire-rated astragal for a pair - is the NGP 125NSS or the Pemko 369 the right call?
The Pemko 369 split astragal seal with pile brush insert is aluminum at 13/32 inch by 11/32 inch and is fire-rated. The NGP 125NSS is a smoke-rated astragal in Type 304 stainless steel with an EPDM seal, BHMA certified to ANSI/BHMA A156.22 for heat, cold and energy performance, and is applied on fire-rated door assemblies among its commercial uses. Check which the opening's listing actually calls for - a smoke seal at the meeting stile and a fire-rated split seal are separate line items on many submittals, and the 125NSS ships as a full 84 inch two-piece set with a brushed #4 stainless finish (US32D, 630).
12) Which lock astragal covers a cylindrical lock only, the Trimco 5001 or the 5002?
The Trimco 5002 lock astragal is stainless steel at 1-9/16 inches by 6 inches and is specified for use with cylindrical locks. The Trimco 5001 lock astragal, also stainless steel, is specified for use with mortise or cylindrical locks. If the pair carries mortise locks, the 5001 covers that case; the 5002 is the cylindrical-only size. Neither is a smoke seal - for a smoke-rated meeting stile the NGP 125NSS carries the EPDM seal and the ANSI/BHMA A156.22 certification.
13) Will a pile brush astragal give me the same seal as the NGP 125NSS EPDM astragal?
They seal by different means. The Pemko 369 split astragal seal and the Pemko 300 Series both use a pile brush insert against the meeting stile, and the Cal-Royal EAST-501 uses a vinyl insert. The NGP 125NSS uses synthetic EPDM rubber in a polypropylene thermoplastic matrix closed cell elastomeric foam, which is the element BHMA certified to ANSI/BHMA A156.22 heat, cold and energy performance tests and rated flame-resistant and moisture-resistant from -81 F to 275 F. A brush or vinyl insert sweeps the gap; the EPDM compresses against it. Where a submittal calls for a smoke-rated gasket at the meeting stile, that distinction is the one to check against the drawing.
14) Will a stainless astragal hold up on a high-traffic or coastal exterior pair?
Type 304 stainless is the corrosion-resistant grade, and the EPDM seal is specified for abrasion resistance, tensile strength and memory, plus resistance to ozone, sunlight and aging. Memory is the one that matters on a heavily used pair: the seal has to come back to shape after thousands of closings instead of taking a set and leaving a gap. On a coastal or wash-down opening, stainless is the reason to pick this over an aluminum astragal.
15) What stainless steel astragals are there besides the NGP 125NSS?
Within the astragals available alongside it, the stainless steel options are the Trimco 5001 lock astragal, for use with mortise or cylindrical locks, and the Trimco 5002 lock astragal at 1-9/16 inches by 6 inches for use with cylindrical locks. Both are lock astragals sized to the lock area. The NGP 125NSS is the full-length stainless choice - Type 304 with a brushed #4 finish (US32D, 630), furnished as an 84 inch two-piece set with a black EPDM seal. The Cal-Royal EAST-501 and both Pemko options are aluminum rather than stainless.
