NGP 143PA-48 – Frequently Asked Questions

1) Is the NGP 143PA astragal meant for a pair of doors or a single door?
The 143PA is a mortised astragal, meaning it recesses into the edge of the door rather than surface mounting over it. The gray polypropylene pile seal closes the gap it sits against, blocking air, dust, and weather. It ships with #6 SMS fasteners. If what you need is a T-astragal that overlaps the meeting stiles of a double door, the Cal-Royal EAST-501 aluminum T-astragal with vinyl insert is built for that, and the Pemko 300 Series adjustable astragal uses a self-adjusting pile brush for the same double-door application.
2) Do I need to rout the door to install a mortised astragal like the NGP 143PA?
Yes. Mortised means the astragal sets into a routed pocket in the door edge rather than screwing onto the face, so the door has to be prepped for it. That is the trade-off: a cleaner finished look and a more secure attachment, but it is a shop or on-site rout, not a surface-applied retrofit. If the doors are already hung and you don't want to machine them, a surface-applied option like the Cal-Royal EAST-501 T-astragal or the Pemko 300 Series adjustable astragal avoids the prep.
3) Will the NGP 143PA astragal work with the mortise lock on my door?
The 143PA is set up for mortise lock openings. It seals the meeting edge and does not itself carry lock prep, so the lock case and cylinder stay where they are. If what you actually need is a plate that covers and protects the lock area at the meeting stile, that is a lock astragal, a different part: the Trimco 5001 stainless lock astragal works with mortise or cylindrical locks, and the Trimco 5002 at 1-9/16 by 6 inches is for cylindrical locks.
4) The opening is a fire-rated pair - which astragal should be specified?
Specify from the peer that carries the rating on its face: Pemko lists the 369 split astragal seal with pile brush insert as fire-rated, in aluminum at 13/32 inch by 11/32 inch. For an institutional or MRO buyer standardizing across a facility, an opening in a rated wall assembly needs the astragal called out as rated in the submittal, and the 369 is the one in this group described that way. The NGP 143PA is a commercial mortised astragal with a polypropylene pile seal and is the choice where the pair is not part of a rated assembly.
5) What is the closest equivalent to the NGP 143PA astragal from another manufacturer?
The Pemko 369 split astragal seal is the nearest match in construction and sealing medium. Like the NGP 143PA, which uses a polypropylene pile seal in an aluminum body, the Pemko 369 is an aluminum astragal seal with a pile brush insert, and Pemko publishes its section size as 13/32 inch by 11/32 inch. The 369 is a split astragal, meaning the seal is carried in two halves for a pair of doors, while the 143PA is a mortised astragal cut into the door edge. For a locksmith or contractor matching an existing pile-sealed aluminum astragal, those two are the pair to compare.
6) The Trimco 5001 and 5002 also say astragal - can either one replace the NGP 143PA?
No, and the word astragal is doing very different work in the two products. The NGP 143PA is a weatherseal astragal: an aluminum extrusion mortised into the door edge carrying a polypropylene pile seal to close the gap against air and dust. The Trimco 5001 and 5002 are lock astragals in stainless steel, intended for use with locks - Trimco specifies the 5001 for mortise or cylindrical locks and the 5002 for cylindrical locks, at 1-9/16 inch by 6 inch. A lock astragal is a short guard piece at the latch area, not a full-length seal, so it will not weatherstrip an opening. Buy on what the part does, not on the shared word.
7) The double doors have gone out of alignment and the gap is uneven - is there an astragal that handles that better than the NGP 143PA?
The Pemko 300 Series is the one built for that condition. Pemko describes the 300 Series as an adjustable astragal with a self-adjusting pile brush for double doors, so the seal takes up variation in the meeting-stile gap rather than depending on a fixed extrusion position. The NGP 143PA is a fixed mortised astragal with a polypropylene pile seal, set by where it is cut into the edge. For a property manager with a fleet of pairs that have racked or settled, the adjustable route is the one that keeps sealing without rehanging the doors.
8) What lengths does the NGP 143PA mortised astragal come in?
Two stock lengths: 48 inches and 120 inches. The 120 inch piece covers a full-height commercial opening in one run, and it can be cut down, so on a fleet of doors of differing heights it is usually the piece you order and trim rather than splicing 48 inch sections.
9) What is the NGP 143PA astragal made of, and will it hold up outdoors?
Aluminum alloy 6063 with a T5 temper, finished anodized. The anodizing is a corrosion-resistant surface treatment, so the extrusion handles exterior exposure and washdown-type environments better than a bare or painted aluminum section. The seal itself is polypropylene pile in gray, which does not absorb water the way a fiber pile would.
10) What is the difference between a pile seal astragal like the NGP 143PA and a vinyl-insert astragal?
It is the sealing medium and how it contacts the opposite door. The NGP 143PA carries a gray polypropylene pile - a brush - in an aluminum alloy 6063 T5 extrusion with an anodized finish. The Cal-Royal EAST-501 is an aluminum T-astragal with a vinyl insert for double doors, so the seal is a solid vinyl fin rather than a brush. Pile sweeps across a moving surface and tolerates a varying gap; vinyl gives a continuous contact face. A T-astragal like the EAST-501 also mounts to the face of the inactive leaf and overlaps the pair, while the 143PA is mortised into the edge and sits flush with it.
11) Is there a simpler astragal to install than the NGP 143PA if the doors are already hung?
Yes - a surface-applied T-astragal avoids the machining. The NGP 143PA is mortised, meaning the door edge is routed to receive the extrusion, which is straightforward on a bench but awkward on doors already in the frame. The Cal-Royal EAST-501 is an aluminum T-astragal with a vinyl insert for double doors, applied to the leaf rather than let into the edge. The Pemko 300 Series adjustable astragal is the other retrofit-friendly route for a pair. Choose the mortised 143PA when the flush edge appearance matters and the doors can be taken down or prepped.
12) Is the NGP 143PA astragal suitable for apartment or residential doors?
It is built as a commercial part, aluminum 6063 T5 with an anodized finish, and it is used in offices, schools, healthcare, retail, warehouses, government buildings, and multi-tenant residential. Multi-family corridor and unit doors are squarely in scope. For a single-family house door with no rout prep and no closer, the duty level is more than the opening needs.
13) Does the NGP 143PA come with screws, or do I need to buy fasteners separately?
Fasteners are in the box. It ships with #6 SMS (sheet metal screws) for mounting into the routed pocket. What is not included is anything for the door prep itself, so plan the rout and any anchoring into a hollow metal door edge as part of the job.
