NGP 9125A 84 SET – Frequently Asked Questions

1) Will the NGP 9125A astragal set work on a pair of fire-labeled doors that need the meeting-edge gap under 1/8 inch?
That is exactly the condition the 9125A set is built around. It meets IBC, NFPA 80, NFPA 105, and NFPA 252 requirements for fire labeled door gap specifications not exceeding 1/8 inch at the meeting edges. It is a two-piece set, so both leaves of the pair get an astragal and the seal closes the gap between them rather than relying on one leaf carrying the whole overlap.
2) Is the NGP 9125A astragal seal rated for rooms with FM200 or Halon fire suppression?
Yes, and that is the specific application it is recommended for. The seal is a synthetic rubber polymer siloxane closed cell sponge with an operating range of -100 F to 500 F, so it holds its flexibility and its seal through the temperature swing those systems produce. Data rooms, telecom rooms, and archive spaces on clean-agent suppression are the typical openings.
3) What lengths does the NGP 9125A smoke-rated astragal set come in, and what door height does that cover?
Two lengths: 84 inches and 96 inches. The 84 inch covers a standard 7 foot leaf and the 96 inch covers an 8 foot leaf. Since it is furnished as a two-piece set, one set handles the pair. For anything shorter, the extrusion is cut to the door height on site.
4) Is the NGP 9125A astragal BHMA certified, and to what standard?
It is BHMA certified to ANSI/BHMA A156.22, specifically the performance tests for heat and cold. For a specifier writing a smoke-barrier or fire-door opening into a healthcare or education project, that is the line item that satisfies the gasketing spec.
5) Should I use a smoke-rated astragal seal or a brush astragal on my pair of doors?
It depends on what the opening has to stop. A silicone sponge astragal like the NGP 9125A seals the meeting edges against air and smoke infiltration and is certified to ANSI/BHMA A156.22 for heat and cold, which is what a smoke barrier or fire-labeled pair calls for. A pile brush astragal, like the Pemko 300 Series adjustable astragal or the Pemko 369 split astragal, uses a brush insert instead, and brush is the choice where you want light weather and dust control with easy door operation rather than a compressed smoke seal. If the opening is on a fire label or in a suppression-system room, take the sponge seal.
6) Are the Trimco 5001 and 5002 lock astragals a substitute for the NGP 9125A astragal seal set?
No. The Trimco 5001 is a stainless steel lock astragal used with mortise or cylindrical locks, and the Trimco 5002 is a stainless steel lock astragal measuring 1-9/16 inch by 6 inch for use with cylindrical locks. Those are short pieces that cover the latch area at the lock, while the NGP 9125A SET is a full-height two-piece aluminum astragal seal set furnished in 84 inch and 96 inch lengths to seal the entire meeting edge. If the goal is sealing the door edge rather than covering the lock, the lock astragals do not do that job.
7) What is the closest fire-rated alternative to the NGP 9125A astragal seal set for the meeting edge of a pair of doors?
The Pemko 369 is the nearest peer. It is a split astragal seal with a pile brush insert, aluminum, fire-rated, in a 13/32 inch by 11/32 inch profile. The NGP 9125A SET is a two-piece aluminum astragal set with high temperature silicone plus seal, BHMA certified to ANSI/BHMA A156.22, rated from -100 F to 500 F, and recommended where FM200 or Halon fire suppression systems are in use. The difference is the sealing element: the Pemko 369 seals with pile brush, the NGP 9125A with silicone sponge, so on an opening where a silicone seal is specified for the suppression system the 369 is not a like-for-like swap.
8) For a pair of exterior double doors that are not fire rated, what astragal should be used instead of the NGP 9125A seal set?
Two peers fit that opening. The Cal-Royal EAST-501 is an aluminum T-astragal with a vinyl insert for double doors, and the Pemko 300 Series is an adjustable astragal with a self-adjusting pile brush for double doors. Both address the gap at the meeting stile without the high temperature silicone construction of the NGP 9125A SET, which is built for fire-rated openings and areas served by FM200 or Halon fire suppression systems.
9) What fasteners come with the NGP 9125A astragal, and can I adjust it after it is up?
Number 6 by 3/4 inch stainless steel sheet metal screws are furnished with the set. The screw holes are slotted, so you can hang it, close the pair, and shift the astragal in or out to dial in the meeting-edge gap before you tighten down. No separate fastener order is needed for a wood or hollow metal door taking a sheet metal screw.
10) What is the NGP 9125A astragal made of, and will it hold up in a corrosive or high-traffic opening?
The extrusion is aluminum alloy 6063 in T5 temper with an anodized finish. That is the standard architectural extrusion alloy, and the anodizing is what carries it through humidity and cleaning chemicals in healthcare and institutional corridors. The seal itself is a closed cell silicone sponge, chosen for memory, so it recovers its shape after repeated closings instead of taking a permanent set.
11) What is the difference between the NGP 9125A astragal set and a T-astragal with a vinyl insert?
Different sealing material and different job. The NGP 9125A carries a silicone sponge seal good from -100 F to 500 F and certified to ANSI/BHMA A156.22, which is why it goes on fire-rated and clean-agent suppression openings. A T-astragal such as the Cal-Royal EAST-501 uses a vinyl insert in an aluminum T section for double doors, and vinyl is a general-purpose weather and light seal, not a high-temperature one. If heat performance is part of the spec, the silicone set is the one that answers it.
12) What is the difference between the Trimco 5001 and 5002 lock astragals when a pair of doors also needs a lock astragal alongside a seal?
Both are stainless steel lock astragals. The Trimco 5001 is specified for use with mortise or cylindrical locks, while the Trimco 5002 is a 1-9/16 inch by 6 inch piece for use with cylindrical locks. Choose by the lock already in the door. Neither one provides the smoke sealing function of the NGP 9125A SET, which is BHMA certified to ANSI/BHMA A156.22 and is the part that closes the gap at the meeting edge.
13) When a double door needs an astragal that takes up varying gap at the meeting stile, does the NGP 9125A seal set handle that or is another product better suited?
The Pemko 300 Series is the adjustable option; it is an adjustable astragal with a self-adjusting pile brush for double doors. The NGP 9125A SET adjusts differently: it has slotted screw holes for precise positioning during installation and is furnished with #6 x 3/4 inch stainless steel sheet metal screws, and it is built to hold fire labeled door gaps at the meeting edge to no more than 1/8 inch per IBC, NFPA 80, NFPA 105 and NFPA 252. On a labeled opening the gap is governed by those requirements rather than taken up by a self-adjusting brush.
14) Can I use the NGP 9125A astragal set on a residential entry door?
It is a commercial product, built for fire-rated and smoke-barrier openings in institutional and commercial buildings, and priced and specified accordingly. Nothing stops it from going on a residential pair mechanically, but the reason to buy it is the ANSI/BHMA A156.22 certification and the -100 F to 500 F silicone seal, and a house door is not asking for either. A vinyl-insert T-astragal is the more usual choice there.
