NGP 336P – Frequently Asked Questions

1) How does the NGP 336P pile astragal install, and do I need to drill the door?
No drilling or screws. The 336P has a pressure-sensitive adhesive backing, so it presses straight onto a clean door face or edge. That makes it a good choice on hollow metal or aluminum doors where you don't want fastener holes, and on occupied buildings where you need the opening back in service fast. Surfaces should be clean and dry for the adhesive to hold.
2) What does the 3/16 inch projection on the NGP 336P mean for door clearance?
The pile stands 3/16 inch off the mounting surface, so it needs roughly that much gap to compress into. On a tight-fitting pair of doors or a door with almost no meeting-edge clearance, the pile will drag. Where you have a wider gap than 3/16 inch, this won't bridge it and you want a deeper pile or an adjustable astragal instead.
3) Is the NGP 336P long enough for a 7 foot door?
Not in one piece. The 336P comes in a 36 inch length, which suits a 3 foot wide opening head or a short section, not the full 84 inch height of a standard commercial door leaf. For a full-height meeting stile you'd need multiple pieces or a longer stock length.
4) Which astragal should I use on a fire-rated pair instead of the NGP 336P?
The Pemko 369 is a split astragal seal with a pile brush insert, 13/32 inch by 11/32 inch aluminum, and is fire-rated. The NGP 336P is a self-adhesive pile astragal with a 3/16 inch projection intended for commercial door sealing. If the opening carries a fire label and the specification calls out a rated astragal, the 369 is the one written for that condition.
5) What is the closest alternative to the NGP 336P pile astragal if the double doors need a rigid astragal rather than an adhesive strip?
The NGP 336P is a self-adhesive pile astragal with a 3/16 inch projection and gray polypropylene pile, applied with pressure-sensitive backing and no fasteners. For a rigid, mechanically fastened astragal on a pair of doors, 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. Those two mount as an extrusion on the door edge; the 336P adds a pile seal to an existing edge condition.
6) Are the Trimco 5001 and 5002 substitutes for the NGP 336P astragal?
No. The Trimco 5001 is a stainless steel lock astragal for use 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. Both are short lock-area guards that cover the gap at the latch. The NGP 336P is a 36 inch self-adhesive pile astragal with gray polypropylene pile that seals the full meeting-edge run. They answer different problems and are not interchangeable.
7) What is the difference between a pile astragal and a T-astragal for double doors?
A pile astragal like the NGP 336P is a low-profile adhesive strip whose polypropylene brush sweeps the gap at the meeting stiles. A T-astragal, such as the Cal-Royal EAST-501 aluminum T-astragal with vinyl insert, is a screw-applied extrusion that overlaps the inactive leaf and physically closes the gap, giving a heavier seal and a positive stop. Use pile when you want a slim retrofit with no fasteners; use a T-astragal when the gap is wide or you need an overlap.
8) I need an astragal that works around a mortise lock on a pair of doors. Is this the right part?
The 336P is a pile weather seal and does nothing for lock clearance. For an astragal that accommodates lock hardware, the Trimco 5001 stainless steel lock astragal is made for use with mortise or cylindrical locks, and the Trimco 5002 at 1-9/16 by 6 inches is for cylindrical locks.
9) What is the difference between the NGP 336P and the Pemko 300 Series for a pair of doors that do not close evenly?
The Pemko 300 Series is an adjustable astragal with a self-adjusting pile brush for double doors, so the seal takes up variation as the leaves meet. The NGP 336P is a fixed 3/16 inch projection self-adhesive pile astragal, which seals against a consistent gap. On a pair with an inconsistent meeting edge, the adjustable 300 Series is the design built for that.
10) If I want a vinyl seal instead of pile at the meeting edge, what do I order instead of the NGP 336P?
The Cal-Royal EAST-501 is an aluminum T-astragal with a vinyl insert for double doors, giving a wiper-style vinyl contact in an aluminum extrusion. The NGP 336P uses gray polypropylene pile on a self-adhesive backing with a 3/16 inch projection. Pile tends to be chosen where smooth door swing and low drag matter; vinyl gives a continuous contact surface.
11) Which pile astragal has a published profile dimension, the NGP 336P or the Pemko 369?
The Pemko 369 split astragal seal with pile brush insert is stated as 13/32 inch by 11/32 inch aluminum. The NGP 336P is specified by its 3/16 inch projection and 36 inch length with gray polypropylene pile. If the drawing calls for a dimensioned aluminum carrier profile, the 369 gives you that figure directly.
12) Can I paint the NGP 336P to match my doors?
Yes. The 336P carries a gray primer finish that is meant to be painted, so it can be finished to match a door or frame color. The pile itself is gray polypropylene and is not painted.
13) Will polypropylene pile hold up on a high-traffic school or hospital door?
Polypropylene pile is resilient and springs back after repeated closings, which is why the 336P is specified on commercial openings including schools, healthcare facilities, offices, retail and multi-tenant residential. The limit is mechanical: because it is adhesive-applied rather than screwed, doors that get abused or cleaned aggressively at the seal line are better served by a fastener-mounted extrusion.
