NGP 144PDKB – Frequently Asked Questions

1) What is a spring adjustable astragal and when do I need one instead of a plain pile astragal?
A spring adjustable astragal keeps constant pressure on the mating door instead of relying on a fixed seal position. The 144PDKB uses a spring loaded system plus adjustment screws on 10 inch centers, so you tune seal contact along the length after the piece is mounted. That matters on pairs of doors that have racked, sagged, or gone out of alignment, where a fixed astragal seals at one end and gaps at the other. On a tight, true pair, a simple split astragal seal such as the Pemko 369 with a pile brush insert does the job without the adjustment.
2) I need an astragal that works around a mortise lock on the active leaf. Is this the right part?
The 144PDKB is a full length meeting stile seal, not a lock astragal. If what you need is the short plate that covers the gap at the lock itself, look at the Trimco 5001 lock astragal in stainless steel, which is made for use with mortise or cylindrical locks, or the Trimco 5002 at 1-9/16 by 6 inches for cylindrical locks. Those are two different jobs and buildings often use both on the same pair.
3) What is the difference between the NGP 144PDKB mortised astragal and the Pemko 300 Series adjustable astragal?
Both are adjustable astragals for double doors that seal with a pile brush. The NGP 144PDKB mortises into the door edge at a 9/16 inch wide by 7/8 inch mortise and uses a spring-loaded system with adjustment screws on 10 inch centers, so the seal contact is tuned after the piece is already mounted. The Pemko 300 Series uses a self-adjusting pile brush, meaning the brush takes up the gap on its own rather than through screw adjustment. If the door edge is already prepped for a mortised astragal, the NGP 144PDKB drops into that prep; if you are working a pair of doors with no mortise cut and do not want to make one, the Pemko 300 is the surface-applied route.
4) Will the NGP 144PDKB astragal let me put a lock in the inactive leaf of a pair of doors?
No. The NGP 144PDKB is a weatherseal astragal: a two-piece mortised aluminum extrusion with a polypropylene pile seal that closes the gap between the leaves against air and moisture. It is not cut to clear lock hardware. When the astragal has to accept a lock, the Trimco 5001 lock astragal in stainless steel is made for use with mortise or cylindrical locks, and the Trimco 5002, at 1-9/16 inch by 6 inch, is made for cylindrical locks. Those are the parts to specify when the strike side of the pair carries a lockset.
5) Is the NGP 144PDKB astragal sold as one piece or do I need two for a pair of doors?
It ships as a two piece set, so one order covers the pair. The #8 x 3/4 inch sheet metal screws are included, which means no separate fastener line on the order.
6) Can I cut the 84 inch NGP astragal down for a shorter door?
The extrusion is aluminum alloy 6063 T5, which cuts cleanly with a miter saw and a non ferrous blade, so trimming an 84 inch piece down to a shorter leaf height is normal field practice. Cut from the end, then reseat the pile so the seal runs the full trimmed length. Going the other way is not possible, so for a door taller than 84 inches you need a longer astragal.
7) What else could I use instead of the NGP 144PDKB mortised astragal on a pair of doors?
Three directions, depending on the door edge. If the edge is not mortised and you do not want to rout it, the Cal-Royal EAST-501 is an aluminum T astragal with a vinyl insert made for double doors. If you want the same self adjusting brush behavior from another maker, the Pemko 300 Series adjustable astragal uses a self adjusting pile brush. If you just need a slim split seal in the meeting stile, the Pemko 369 runs 13/32 by 11/32 inch aluminum with a pile brush insert.
8) I am standardizing weatherseal across a building. Which astragals are the pile-brush type?
Three of the common pairs-of-doors astragals seal with a brush rather than a bulb. The NGP 144PDKB uses a gray polypropylene pile seal, mortised, spring adjustable with screws on 10 inch centers, in aluminum alloy 6063 T5 with a dark bronze finish at 84 inches. The Pemko 300 Series uses a self-adjusting pile brush. The Pemko 369 is a split astragal seal with a pile brush insert at 13/32 inch by 11/32 inch, aluminum and fire-rated. The Cal-Royal EAST-501 is the outlier in that group, sealing with a vinyl insert on an aluminum T-astragal. Where finish match across the facility matters, the 144PDKB is the dark bronze option.
9) What is the difference between the Trimco 5001 and Trimco 5002 lock astragals?
The Trimco 5001 is a stainless steel lock astragal for use with mortise or cylindrical locks. The Trimco 5002 is a stainless steel lock astragal measuring 1-9/16 inch by 6 inch and is called out for cylindrical locks. If the pair carries a mortise lock, the 5001 is the one that covers it; the 5002 is the shorter cylindrical-lock piece. Neither seals the meeting stile the way a pile astragal does.
10) Can I use a T-astragal with a vinyl insert instead of the NGP 144PDKB pile astragal?
They seal differently. The Cal-Royal EAST-501 is an aluminum T-astragal with a vinyl insert for double doors, so the seal is a solid vinyl bulb carried on a T-shaped extrusion applied to the leaf. The NGP 144PDKB seals with a gray polypropylene pile brush and mortises into a 9/16 inch by 7/8 inch prep, with spring-loaded pressure and adjustment screws on 10 inch centers holding the brush against the mating leaf. Pile tolerates sliding contact and out-of-plumb leaves; a vinyl insert compresses. Choose on how the pair meets and on whether the edge is mortised or you are surface-applying.
11) The gap between our double doors is narrow. Is there a smaller-profile astragal seal than the NGP 144PDKB?
The Pemko 369 split astragal seal carries a pile brush insert in an aluminum section measuring 13/32 inch by 11/32 inch, which is a small section for tight meeting stiles. The NGP 144PDKB takes a 9/16 inch wide by 7/8 inch mortise in the door edge, so it needs a deeper prep and more edge material to sit in. Measure the existing prep and the leaf-to-leaf gap before choosing between them.
12) Will the dark bronze astragal match the rest of my commercial door hardware?
Dark bronze anodized aluminum is the finish, which lines up with the standard dark bronze storefront and commercial door package (the 10B/613 family of bronze finishes on adjacent hardware). Dark bronze is the only model offered on the 144PDKB, so if the opening is aluminum or clear anodized you would spec a different astragal rather than expect a second finish here.
13) Does the pile seal on the NGP 144PDKB hold up outdoors?
The seal is gray polypropylene pile, which sheds moisture rather than absorbing it, and the carrier is 6063 T5 aluminum for corrosion resistance. It is rated by the manufacturer as a commercial product. Pile seals handle air infiltration and light weather at the meeting stile; for a fully weather exposed pair you would pair it with a threshold and door bottom to close the rest of the perimeter.
