NGP 125NA 84 SET – Frequently Asked Questions

1) Will the NGP 125NA astragal meet the 1/8 inch maximum gap requirement at the meeting edge of a pair of fire labeled doors?
That is exactly what the 125NA is built to do. It mounts at the meeting edge of a pair and maintains the 1/8 inch maximum gap that code requires between fire labeled doors. It is BHMA certified to ANSI/BHMA A156.22 for heat, cold, air infiltration and smoke infiltration, and it meets IBC, NFPA 80, NFPA 105, and NFPA 252 requirements for fire-labeled openings. If your inspector is writing you up for gap at the meeting stile on a rated pair, this is the part that closes it.
2) What comes in the NGP 125NA 84 inch astragal set, and do I need to buy fasteners separately?
It ships as a two-piece set, one piece for each leaf of the pair, with gray EPDM seal in anodized aluminum extrusion. Mounting screws are included: #6 x 3/4 inch stainless steel sheet metal screws. The screw holes are slotted, so you can shift the pieces after they are started to dial in the closure before you snug them down. You are not sourcing hardware separately for this one.
3) Do I need an astragal on both doors of a pair, or just one leaf?
The 125NA is furnished as a two-piece set, so both leaves get a piece. That is the difference between this and a single-leaf overlapping astragal: the two halves meet each other at the meeting stiles instead of one leaf carrying the whole seal. Order one 84 inch set per pair of doors, not one per leaf.
4) Should I use a smoke-rated astragal like the NGP 125NA or a brush-seal astragal on my double doors?
Depends on what the opening has to stop. A rubber-seal astragal like the 125NA compresses to a continuous EPDM contact line and is the one to use where smoke and air infiltration are the point, which is why it carries ANSI/BHMA A156.22 testing for smoke and air. A pile brush astragal, like the Pemko 300 Series self-adjusting brush astragal or the Pemko 369 split astragal with pile brush insert, sweeps light, dust and drafts and takes misalignment more forgivingly, but brush is not a smoke seal. Rated pair, smoke partition, or a stair enclosure: use the rubber. Interior pair where you just want the daylight gap covered: brush is easier to live with.
5) My double doors have a mortise lock in the active leaf. Is the NGP 125NA the astragal I need?
Not for that job. The 125NA is a full-height sealing astragal, a two-piece EPDM and aluminum set for closing the meeting-edge gap. If what you need is a short metal plate that covers the latch area and protects the lock at the meeting stile, that is a lock astragal: the Trimco 5001 in stainless steel is made for mortise or cylindrical locks, and the Trimco 5002, 1-9/16 by 6 inches in stainless, is the cylindrical-lock version. Some openings take both, a lock astragal at the latch and a gasketing astragal for the seal.
6) Is a Trimco 5001 or 5002 lock astragal a substitute for the NGP 125NA?
No, despite the shared word in the name they do two different jobs. The Trimco 5001 and 5002 are stainless steel lock astragals meant to be used with locks, the 5001 with mortise or cylindrical locks and the 5002 in a 1-9/16 inch x 6 inch size for cylindrical locks. They are short plates that cover the gap at the lock area of a pair. The NGP 125NA is a full-height 84 inch two-piece anodized aluminum astragal set with a gray EPDM seal, screwed on with #6 x 3/4 inch stainless steel sheet metal screws through slotted holes, and BHMA certified to ANSI/BHMA A156.22 for heat, cold, air infiltration and smoke infiltration. Ordering a 5001 or 5002 when the specification calls for a smoke seal down the full meeting edge will leave the opening unsealed above and below the lock.
7) Will an EPDM astragal hold up on an exterior pair, or is it only for interior smoke doors?
EPDM is the right polymer for outside work. The 125NA seal runs from -60 F to 250 F and NGP rates it good against ozone, sunlight and aging, with very good abrasion resistance, tensile strength and memory. It is also flame resistant and moisture resistant. So a freezer vestibule, an unconditioned warehouse pair, or a sun-exposed entrance is all inside its range, and the memory means it recovers its shape after years of the doors slamming into it.
8) Can I adjust an astragal after mounting if the doors do not close evenly against it?
Yes, and that is the point of the slotted holes on the 125NA. The #6 x 3/4 inch stainless steel screws run in slots, so you can start the fasteners loose, swing the pair to check contact along the full 84 inches, shift the piece in or out until the seal compresses evenly at top and bottom, then tighten. On an out-of-plumb frame that adjustment is the difference between a seal that passes an inspection and one that whistles at the head.
9) What is the difference between the NGP 125NA and a T-astragal with a vinyl insert?
Two different profiles for two different problems. The 125NA is a two-piece set, one on each leaf, with EPDM seal and BHMA A156.22 certification for heat, cold, air and smoke, which is what puts it on rated and smoke-partition openings. A T-astragal such as the Cal-Royal EAST-501 aluminum T-astragal with vinyl insert mounts to one leaf and overlaps the other, covering the gap with a T profile. The overlapping style closes the sightline on a standard pair; the split two-piece set is what you specify when the seal has to be tested for smoke infiltration.
10) How does the Cal-Royal EAST-501 T-astragal compare to the NGP 125NA?
The Cal-Royal EAST-501 is an aluminum T-astragal with a vinyl insert for double doors, so the seal element is vinyl and the extrusion is a T profile that overlaps the meeting edge. The NGP 125NA is an anodized aluminum two-piece set, aluminum alloy 6063 in T5 temper, with a gray EPDM synthetic rubber seal rated -60 F to 250 F and BHMA certification to ANSI/BHMA A156.22 for heat, cold, air infiltration and smoke infiltration, meeting IBC, NFPA 80, NFPA 105 and NFPA 252 requirements for fire-labeled doors. Both are surface applied to the meeting edge of a pair. The deciding question is the opening: a fire-labeled or smoke barrier pair in a hospital, school or multi-tenant corridor is where the certified EPDM 125NA belongs, and a T-astragal with a vinyl insert is a weather and light seal for an unrated pair.
11) What is the difference between an EPDM seal astragal and a pile brush astragal at the meeting edge?
The NGP 125NA uses a gray EPDM synthetic rubber polymer seal rated from -60 F to 250 F, with very good abrasion resistance, tensile strength and memory, flame resistant and moisture resistant, and good resistance to ozone, sunlight and aging. The Pemko 300 series adjustable astragal and the Pemko 369 split astragal both seal with pile brush instead, the 300 series with a self-adjusting pile brush. A brush closes the meeting edge with fiber, which tolerates a wider and less consistent gap between the two leaves; a compressible EPDM bulb closes it with rubber that takes a set against the mating leaf. For a smoke-rated opening where air and smoke infiltration performance is the point, the 125NA is the EPDM answer, and it is BHMA certified to ANSI/BHMA A156.22 for exactly those tests.
12) The gap between our double doors is uneven top to bottom. Is there an astragal that handles that better than the NGP 125NA?
Look at the Pemko 300 series adjustable astragal, which uses a self-adjusting pile brush for double doors and is built to take up variation across the meeting edge. The NGP 125NA handles adjustment a different way: it ships as a two-piece set with #6 x 3/4 inch stainless steel sheet metal screws and slotted holes so each piece can be shifted during installation to bring the seal onto the mating leaf, and it is designed to hold the 1/8 inch maximum gap required at the meeting edge between fire labeled doors. On a fire or smoke rated pair, the doors themselves have to meet that gap tolerance, so the 125NA with its slotted adjustment and EPDM seal is the code path; a self-adjusting brush is the choice where the opening is not rated and the leaves are simply out of true.
13) Will an anodized aluminum astragal match the aluminum storefront doors we already have?
The 125NA extrusion is anodized aluminum with a gray EPDM seal, so it reads as clear anodized against typical aluminum entrance framing rather than as a painted or plated finish. Anodized aluminum is the only finish the 125NA set is furnished in, so there is no color decision to make when you standardize it across a building.
14) What is the NGP 125NA astragal extrusion actually made of, and is it strong enough for a high traffic pair?
The body is 6063 aluminum alloy in T5 temper, the standard architectural extrusion alloy and temper for door gasketing, and the seal is synthetic rubber polymer EPDM with very good abrasion resistance and memory. That combination is what NGP builds for commercial service: schools, hospitals, retail, warehouse and multi-tenant residential openings where the pair cycles all day and the seal has to keep coming back to shape.
15) Is stainless hardware included on the NGP 125NA, or will the screws rust on a damp opening?
Fasteners are stainless steel, #6 x 3/4 inch sheet metal screws, so the mounting hardware itself will not bleed rust down an anodized extrusion on a loading dock or a pool-area pair. The seal material is moisture resistant EPDM, so the whole assembly is suited to wet-side openings.
