NGP 109NA-84 – Frequently Asked Questions

1) Will the NGP 109N astragal fit a standard 7 foot commercial door?
The 109N comes pre-cut at 84 inches, which covers a standard 7 foot door leaf with no field cutting. On a taller opening you cut aluminum extrusion to length, and on shorter leaves you trim from the bottom. The slotted screw holes let you shift the piece up or down for alignment before you set the fasteners.
2) Which astragal do I use on a pair of doors, an overlapping one or a split seal?
An overlapping astragal like the NGP 109N mounts on the inactive leaf and laps the meeting stile of the active leaf, so it closes the gap in one piece and gives you a positive stop. A split astragal puts half the seal on each leaf instead, which is what you want when both leaves need to open independently without one fouling the other. The Pemko 369 split astragal with a pile brush insert, at 13/32 by 11/32 inch, is the split-type alternative. If the meeting stiles move out of alignment over time, the Pemko 300 Series adjustable astragal with a self-adjusting pile brush takes up that variation.
3) Is the NGP 109N astragal rated for an unheated warehouse or a cold-climate exterior door?
Rated -20 F to 200 F, and BHMA certified to the ANSI/BHMA A156.22 heat and cold performance tests. That range covers an unconditioned warehouse, a loading dock, and a northern exterior opening. The neoprene and closed-cell chloroprene foam seal is also called out for resistance to ozone, sunlight, and aging, which is what kills a cheap vinyl bulb seal on a sun-facing door.
4) Can I use the NGP 109N astragal on a pair of doors that has a mortise lock in the meeting stile?
No. The 109N is a full 84 inch overlapping weatherseal astragal that runs the height of the leaf, so it laps over the meeting stile where the lock and strike sit. When you need to protect the latch area on a lockset instead, use a lock astragal: the Trimco 5001 in stainless steel works with mortise or cylindrical locks, and the Trimco 5002, 1-9/16 by 6 inches, is for cylindrical locks. Those are short pieces at the lock, not a full-height seal.
5) What is the closest equivalent to the NGP 109N overlapping astragal for a pair of commercial doors?
The Cal-Royal EAST-501 is the nearest cross-brand match: an aluminum T-astragal with a vinyl insert for double doors. Both are aluminum-bodied astragals that seal the meeting stiles of a pair, and both differ mainly in profile and sealing element. The NGP 109N is an overlapping profile with a neoprene seal in a synthetic rubber polymer blend, in aluminum alloy 6063 T5 temper, BHMA certified to ANSI/BHMA A156.22 heat and cold performance tests, and rated from -20 F to 200 F. The EAST-501 uses a T profile with a vinyl insert, so it seats between the two leaves rather than lapping over the inactive leaf. Confirm which profile the pair was prepped for before swapping, since an overlapping astragal needs clearance over the inactive door face and a T-astragal does not.
6) What astragal should I use instead of the NGP 109N on a fire-rated pair of doors?
The Pemko 369 split astragal seal is the fire-rated option in the comparable group. It is an aluminum seal with a pile brush insert in a 13/32 inch by 11/32 inch profile, described as fire-rated, and it splits so a section mounts on each leaf of the pair. The NGP 109N carries BHMA certification to ANSI/BHMA A156.22 for heat and cold performance and is built from aluminum alloy 6063 T5 temper with a neoprene seal, which covers weather and temperature performance from -20 F to 200 F rather than a fire label. On an opening where the door assembly's fire rating governs the gasketing, specify the 369; where the requirement is weathersealing on a non-rated exterior or interior pair, the 109N applies.
7) Is a Trimco 5001 lock astragal a substitute for the NGP 109N astragal?
No, despite the shared word. The Trimco 5001 is a lock astragal in stainless steel, used with mortise or cylindrical locks, and the companion Trimco 5002 is a 1-9/16 inch by 6 inch stainless piece used with cylindrical locks. Those are short pieces that cover the latch and lock area of the opening. The NGP 109N is a full-height 84 inch overlapping astragal in aluminum alloy 6063 T5 temper with a neoprene seal, made to close the gap along the entire meeting stile of a pair and BHMA certified to ANSI/BHMA A156.22 for heat and cold performance. If the requirement is weather and light sealing down the full door height, the 5001 and 5002 do not do that job; if the requirement is guarding the latch area at a lockset, the 109N is not the part.
8) Do I need to buy screws separately for the NGP 109N astragal?
Fasteners ship with it. The 109N includes #6 x 1 inch and #6 x 3/4 inch stainless steel sheet metal screws, so a hollow metal or wood door install is a one-box job. Stainless fasteners matter on an exterior opening where plated steel screws would rust-streak the door face.
9) What finishes does the NGP 109N overlapping astragal come in?
Three: anodized aluminum, gold, and dark bronze. Dark bronze is the one that disappears against bronze-anodized storefront and dark-painted hollow metal; anodized aluminum matches clear-anodized frames and most mill-finish aluminum entrances. If you are standardizing a building, pick the one that matches the existing door edge and threshold hardware rather than the door paint.
10) Is a neoprene seal or a pile brush astragal better for keeping weather and dust out?
The compression seal on the 109N is a synthetic rubber polymer blend, PVC with nitrile (NBR) and closed-cell chloroprene foam, which seals against air and water when the leaf closes on it. A brush-type astragal sweeps rather than compresses, so it tolerates misalignment and repeated traffic but does not seal weather as tightly. Pemko's 300 Series adjustable astragal and the 369 split astragal both use pile brush inserts. For an exterior opening choose the compression seal; for a high-cycle interior pair with drifting alignment, the brush is more forgiving.
11) What is the difference between the NGP 109N and a T-astragal for double doors?
The 109N is an overlapping type: it mounts flat on the inactive leaf face and laps across the gap. A T-astragal, like the Cal-Royal EAST-501 aluminum T-astragal with a vinyl insert, sets into or against the edge of the meeting stile and projects a T-shaped profile between the leaves. The overlapping style is the retrofit-friendlier of the two because it screws to the door face rather than requiring edge prep.
12) The meeting stiles on my double doors do not line up consistently. Is there an astragal better suited than the NGP 109N?
The Pemko 300 Series adjustable astragal is built for that condition: it is an adjustable astragal with a self-adjusting pile brush for double doors, so the brush takes up variation as the leaves close against each other. The NGP 109N seals with a neoprene element in a synthetic rubber polymer blend and mounts with slotted screw holes that allow alignment adjustment at install, which handles setting the position once but is a fixed contact seal in service. For a pair that racks, sags seasonally, or sees heavy traffic, the self-adjusting brush of the 300 Series maintains contact through the movement; for a stable pair where a compression seal against weather and temperature is the goal, the 109N neoprene seal is the tighter closure.
13) Should I specify a brush-insert astragal or a neoprene-seal astragal on a commercial pair?
It comes down to what the opening has to stop and how much the leaves move. The NGP 109N uses a neoprene seal in a synthetic rubber polymer blend of PVC, nitrile rubber and chloroprene closed cell elastomeric foam, giving a compression contact seal with resistance to ozone, sunlight and aging and a service range of -20 F to 200 F. The brush alternatives seal by sweeping: the Pemko 369 split astragal carries a pile brush insert in a 13/32 inch by 11/32 inch aluminum profile, and the Pemko 300 Series uses a self-adjusting pile brush. A brush tolerates gap variation and repeated cycling; a neoprene compression seal closes tighter against air and weather. Exterior pairs and temperature-separated spaces are the usual case for the 109N, while high-cycle interior pairs are where the brush profiles are typically specified.
14) Is the NGP 109N astragal suitable for a hospital or school corridor pair, or is it exterior only?
It is a commercial-rated part and NGP lists it for healthcare, educational, government, office, retail, industrial, and multi-tenant residential buildings. The 6063 T5 aluminum extrusion holds its shape under repeated closing, and the seal material is called out as flame and moisture resistant. It seals and stops; if the opening also carries a smoke or fire label, verify the specific listing required for that assembly before you specify it.
15) I need a lock astragal for an opening with a mortise lock. Which one works, and how does it relate to the NGP 109N?
The Trimco 5001 lock astragal in stainless steel is the one described for use with mortise or cylindrical locks, while the Trimco 5002, at 1-9/16 inch by 6 inch in stainless steel, is described for use with cylindrical locks. So a mortise-locked pair points to the 5001. Neither replaces the NGP 109N, which is an 84 inch overlapping astragal in aluminum alloy 6063 T5 temper with a neoprene seal that runs the meeting stile for weathersealing. On a pair that needs both latch-area protection and a continuous seal, they are separate line items rather than an either/or.
