NGP 136P-84 – Frequently Asked Questions

1) What is the NGP 136P astragal and where does it mount on a pair of doors?
The NGP 136P is a mortised astragal: an aluminum extrusion with a gray polypropylene pile insert that recesses into a mortise cut in the door edge rather than surface mounting on the face. It closes the meeting gap between a pair of doors, sealing against air, moisture, and sound transmission. Because it sits in a mortise, the door edge has to be routed to accept it, so it is a better fit for new doors or a shop prep than a quick field retrofit on an existing pair.
2) What size mortise do I need to rout for the NGP 136P astragal?
Cut the mortise 7/16 inch wide by the depth you want the extrusion to sit at. That 7/16 inch width is the number that decides whether the part drops in, so set the router or shaper to it before running the edge. The 136P ships with #2 sheet metal screws for fastening once it is seated.
3) Does the NGP 136P astragal include a cutout for a mortise lock or a cylindrical lockset?
The 136P is a weatherseal astragal, not a lock astragal, so it carries no lock or cylinder prep. If you need the astragal to clear or shield hardware at the meeting stile, the Trimco 5001 stainless steel lock astragal is made for use with mortise or cylindrical locks, and the Trimco 5002 (1-9/16 inch x 6 inch, stainless) is for use with cylindrical locks.
4) Is there a pile astragal that does not require mortising the door edge?
Yes. The NGP 136P is mortised, so it needs a 7/16 inch wide cut in the edge of the door. The Pemko 300 Series is an adjustable astragal with a self-adjusting pile brush for double doors, and the Cal-Royal EAST-501 is an aluminum T-astragal with a vinyl insert for double doors, both surface-mounted styles for a meeting stile. On retrofit work where cutting a mortise into an existing door is not practical, those are the alternatives; on new doors or where the mortise can be routed, the 136P keeps the seal recessed into the edge.
5) What astragal should I use on a fire-rated pair of doors?
Look to the Pemko 369 for that opening. It is a split astragal seal with a pile brush insert, aluminum, 13/32 inch by 11/32 inch, and it is fire-rated, so it is the one in the group carrying that designation. The NGP 136P is a commercial mortised astragal with polypropylene pile in aluminum alloy 6063 T5, specified for commercial office, educational, healthcare, retail, industrial, multi-tenant residential, and government buildings where sealing rather than a fire label drives the selection.
6) What is the difference between the NGP 136P mortised astragal and a Trimco 5001 lock astragal?
They solve different problems on a pair of doors. The NGP 136P is a full-length mortised astragal with gray polypropylene pile, mortised into a 7/16 inch wide cut and cut to 84 or 96 inch lengths, so it seals the meeting stile against air and light along the whole height of the opening. The Trimco 5001 is a stainless steel lock astragal for use with mortise or cylindrical locks, a short piece at the lock location that covers the gap where the latch is rather than sealing the full stile. If the goal is weatherstripping the meeting edge, the 136P is the part; if the goal is protecting or concealing the latch area, the 5001 is.
7) What is the closest equivalent to the NGP 136P from Pemko?
The Pemko 369 is the nearest match in construction. It is a split astragal seal with a pile brush insert, aluminum, at 13/32 inch by 11/32 inch, and it is fire-rated. Like the NGP 136P it uses a pile brush rather than a vinyl or rubber bulb, and the 136P is built from aluminum alloy 6063 T5 with gray polypropylene pile in a 7/16 inch wide mortise. Where a fire-rated opening is involved, the 369 carries that rating; where the detail calls for the NGP profile, the 136P covers 84 and 96 inch door heights.
8) Will the mill aluminum finish on the NGP 136P hold up on an exterior door?
Mill aluminum is the raw, uncoated finish on aluminum alloy 6063 T5, and it resists corrosion without any additional coating. That makes it a workable exterior choice, though the natural mill look will not match anodized or painted trim, so on a visible storefront or lobby pair expect it to read as bare aluminum rather than blend with the frame.
9) Do I need anything besides the astragal to install the NGP 136P?
Fasteners come in the box, #2 sheet metal screws, so the mounting hardware is handled. What you supply is the edge prep: a 7/16 inch wide mortise routed to your chosen depth along the meeting stile, plus a saw to cut the 84 or 96 inch extrusion to the door height.
10) Should I use a pile brush astragal or a vinyl insert astragal on a double door?
The two seal differently. The NGP 136P uses gray polypropylene pile mortised into the door edge, which sweeps against the mating surface and tolerates repeated contact from high-traffic swings. The Cal-Royal EAST-501 is an aluminum T-astragal with a vinyl insert for double doors, a compression-style seal on a T profile that covers the gap between the leaves. Pile is common where doors cycle constantly and the seal has to wipe rather than compress; vinyl on a T profile fills a wider visible gap between leaves. Both are aluminum bodies, and the 136P comes in 84 and 96 inch lengths with mill aluminum finish and #2 SMS fasteners included.
11) For a pair of doors that never close tightly against each other, is a pile astragal or an adjustable one the better choice?
An adjustable astragal absorbs the variation. The Pemko 300 Series is an adjustable astragal with a self-adjusting pile brush for double doors, which lets the seal follow a meeting stile that is out of alignment or has settled. The NGP 136P is a fixed mortised astragal set into a 7/16 inch wide by desired depth cut, so it seals well on a consistent gap but does not take up slack across the height of the door. On a fleet of older double doors with inconsistent gaps, the adjustable style is the one to spec; on doors hanging true, the mortised 136P gives a recessed seal in 84 or 96 inch lengths.
