NGP 125NDKB 84 SET – Frequently Asked Questions

1) Is the 84 inch NGP astragal one piece or does it cover both leaves of a double door?
It ships as a matched two-piece set in dark bronze, one piece for each meeting edge, so a single order covers the pair. Length is 84 inches, matching a standard 7 foot door height. If your openings are taller than 84 inches, this set is not the right length.
2) I need an astragal on a pair of exterior aluminum doors that is not a smoke seal - what should I use instead?
For a weather-facing pair where smoke infiltration certification is not the driver, the Cal-Royal EAST-501 is an aluminum T-astragal with a vinyl insert for double doors. The NGP 125NDKB 84 SET is the choice where the assembly is fire labeled - it is a neoprene smoke-rated set BHMA certified to ANSI/BHMA A156.22 for heat, cold, air and smoke infiltration and built around the code requirement for a 1/8 inch maximum gap at the meeting edge between fire labeled doors.
3) What is the closest equivalent to the NGP 125NDKB astragal for sealing the meeting edge of a pair of fire labeled doors?
The NGP 125NDKB 84 SET is a two-piece neoprene smoke-rated astragal with an EPDM seal in an aluminum 6063 T5 extrusion, BHMA certified to ANSI/BHMA A156.22 for heat, cold, air infiltration and smoke infiltration. The nearest peer for the same meeting-edge job is the Pemko 369 split astragal seal, an aluminum fire-rated split astragal with a pile brush insert measuring 13/32 inch by 11/32 inch. Both are split, two-part designs applied to the meeting edges of a pair, but the NGP uses an EPDM rubber seal while the Pemko 369 seals with a pile brush.
4) Will a Trimco 5001 or 5002 lock astragal do the same job as the NGP 125NDKB?
No - those are a different kind of part despite the shared name. 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 pieces that guard the latch area at a lock. The NGP 125NDKB 84 SET is a full-height 84 inch two-piece astragal with an EPDM seal, BHMA certified to ANSI/BHMA A156.22 for air and smoke infiltration, intended to seal the entire meeting edge of a pair.
5) What is the NGP 125NDKB astragal made of, and will the seal hold up in an unconditioned building?
Frame is aluminum alloy 6063 T5 temper. The seal is synthetic EPDM rubber in a polypropylene thermoplastic matrix, rated from -81 F to 275 F and flame resistant, with strong resistance to ozone, sunlight and aging plus good abrasion resistance, tensile strength and memory. That temperature band covers unheated warehouse and exterior-adjacent service openings.
6) Do I need to buy fasteners to install the NGP smoke-rated astragal?
No. The set comes with #6 x 3/4 inch stainless steel sheet metal screws. The screw holes are slotted, so you can shift the astragal to line up the meeting edge before tightening rather than being locked to the first hole location.
7) Is there an astragal that self-adjusts to a varying gap instead of using a fixed EPDM seal?
Yes. The Pemko 300 Series is an adjustable astragal with a self-adjusting pile brush for double doors, which lets the seal take up variation in the gap between the two leaves. The NGP 125NDKB 84 SET instead uses a fixed synthetic EPDM rubber seal in a polypropylene thermoplastic matrix, with slotted screw holes in the aluminum extrusion for alignment during installation, and is BHMA certified to ANSI/BHMA A156.22 for smoke infiltration.
8) What is the difference between an EPDM rubber seal and a pile brush seal on a double-door astragal?
An EPDM seal, as used on the NGP 125NDKB 84 SET, is a synthetic rubber compression seal in a polypropylene thermoplastic matrix with very good abrasion resistance, tensile strength and memory and excellent resistance to ozone, sunlight and aging, rated from -81 F to 275 F. A pile brush seal, as used on the Pemko 369 split astragal and the Pemko 300 Series adjustable astragal, sweeps the gap with filament rather than compressing against it, and on the 300 Series it is self-adjusting to the gap. Choose by whether the opening needs a compression seal or a brush that tolerates gap variation.
9) Is the NGP 125NDKB astragal suitable for apartment corridor doors and hospital cross-corridor pairs?
Yes, it is a commercial-duty part and those are its normal homes: multi-tenant residential, healthcare, schools, offices, industrial buildings and government facilities. Because it is certified to A156.22 for smoke infiltration, it suits smoke barrier pairs under NFPA 105 as well as fire rated pairs.
10) I need the astragal to match dark bronze hardware. What finish does the NGP 125NDKB come in?
Dark bronze is the finish on this set, which is the only way it is configured. It is a good match to dark bronze anodized aluminum storefront and to bronze-finished door hardware on the same openings.
