NGP 137NA 36X84 – Frequently Asked Questions

1) Can the NGP 137NA perimeter seal be used on a 3-hour rated hollow metal fire door?
Yes. The 137NA perimeter seal is UL certified to CAN/ULC-S104 and ANSI/UL10B for hollow metal fire doors rated up to 3 hours, and for wood fire doors up to 90 minutes. So on a 3-hour hollow metal opening it is within its listing; on a wood door, 90 minutes is the ceiling regardless of what the frame is rated for.
2) Does the NGP 137NA gasketing meet positive pressure requirements for NFPA 80 fire door assemblies?
It does. The 137NA is UL certified to ANSI/UL10C for positive pressure, and the listing ties that to compliance with IBC, NFPA 80 and NFPA 252. That is the certification an inspector looks for when a fire door assembly is tested under positive pressure rather than the older neutral pressure method, so it is the seal to specify when the AHJ is enforcing current code.
3) Will the NGP 137NA perimeter seal work as smoke and draft control gasketing?
Yes, it carries smoke and draft control certification to ANSI/UL1784 Category H. That is the listing required on smoke barrier doors in healthcare and multi-tenant corridors, so the same head-and-jamb seal covers both the fire rating and the S-label smoke requirement without adding a separate smoke gasket.
4) What sizes does the NGP 137NA perimeter seal set cover, and which one do I order for a standard commercial opening?
The 137NA ships as a set in three sizes: 36 x 84 inches, 36 x 96 inches, and 72 x 84 inches. The first number is the head length and the second the jamb length. A standard single 3-0 x 7-0 opening takes the 36 x 84 set. An 8-foot single door takes 36 x 96. A pair of 3-0 doors in one frame takes the 72 x 84 set, which gives you enough head stock to run the full width of the pair.
5) Is the seal on the NGP 137NA a compression seal or a sweep, and where does it mount?
It is a perimeter seal, meaning it mounts to the head and both jambs of the frame and the door compresses against the EPDM insert when it closes. It does not seal the bottom of the door. If you need the threshold gap closed too, you pair it with a door bottom or an automatic door bottom; the perimeter seal handles the three sides only.
6) What is the closest aluminum-channel perimeter gasketing to the NGP 137NA?
The Cal-Royal PG-601 is the near equivalent in form: an aluminum channel perimeter gasketing that mounts to the frame the same way, using a vinyl insert as the sealing element. The NGP 137NA uses synthetic EPDM rubber in a polypropylene thermoplastic matrix set in an aluminum alloy 6063 T5 temper channel, finished satin aluminum clear anodized, and its slotted screw holes take the furnished #6 x 3/4 inch stainless steel sheet metal screws for adjustment at install. Both are frame-applied perimeter seals for commercial openings; the difference a specifier weighs is the insert material, EPDM against vinyl.
7) For a fire-rated opening, which perimeter seal carries the certifications the code official will ask for?
The NGP 137NA is UL certified to CAN/ULC-S104 and ANSI/UL10B for hollow metal fire doors rated up to 3 hours and wood fire doors up to 90 minutes, and UL certified to ANSI/UL10C for positive pressure per IBC, NFPA 80 and NFPA 252. It also carries smoke and draft control certification to ANSI/UL1784 Category H and BHMA certification to ANSI/BHMA A156.22 for the heat and cold performance tests. The Cal-Royal PG-601 is an aluminum channel perimeter gasketing with a vinyl insert, so on an opening where the fire and smoke listings are what the inspector is checking, the 137NA is the one whose certifications are stated to that level.
8) Do I need to buy fasteners separately for the NGP 137NA perimeter seal?
No, screws come with it. The set is furnished with #6 x 3/4 inch stainless steel sheet metal screws. The screw holes in the aluminum carrier are slotted, so you can shift the seal in or out against the door face after the screws are started and set the compression before you snug them down. That matters on a fire door, where too much compression drags the closer and too little leaves a light gap at the top corner.
9) Will EPDM perimeter gasketing hold up in an unconditioned warehouse or an exterior door in a cold climate?
The 137NA is rated from -81 F to 275 F, which covers freezer vestibules, unheated warehouse openings, and exterior doors anywhere in North America. The EPDM has good resistance to ozone, sunlight and aging, plus very good abrasion resistance and memory, so it recovers its shape rather than taking a permanent set after years of door slams. The carrier is 6063 T5 aluminum in a satin clear anodized finish, which does not rust at an exterior opening.
10) Is the NGP 137NA rated for heat and cold performance under ANSI/BHMA?
Yes. Beyond the UL fire listings, the 137NA is BHMA certified to the ANSI/BHMA A156.22 performance tests for heat and cold. A156.22 is the standard that covers door gasketing and edge seals, so a spec calling out A156.22 gasketing is satisfied by this product.
11) How does the NGP 137NA compare to Cal-Royal PG-601 perimeter gasketing?
Both are aluminum channel perimeter gasketing for the head and jambs. The difference is the insert material: the Cal-Royal PG-601 uses a vinyl insert, while the 137NA uses EPDM rubber in a polypropylene thermoplastic matrix, rated -81 F to 275 F, with UL fire listings to CAN/ULC-S104, ANSI/UL10B and ANSI/UL10C. If the opening is a labeled fire or smoke door, the 137NA is the one carrying those listings. For a non-rated interior opening where you just want a compression seal in an aluminum channel, the PG-601 does that job.
12) Can I standardize one perimeter seal across fire doors, smoke barriers, and exterior openings in the same building?
That is what the 137NA is built for. One part number covers labeled hollow metal fire doors to 3 hours, wood fire doors to 90 minutes, ANSI/UL1784 Category H smoke and draft openings, and exterior doors at -81 F to 275 F. For a facility group buying across corridors, stairwells and exterior entries, that means one line item and one install detail instead of three, with the sizes chosen per opening from the 36 x 84, 36 x 96 and 72 x 84 sets.
13) Does the EPDM seal or a vinyl-insert gasket suit a freezer vestibule or an exposed exterior door better?
The NGP 137NA seal element is synthetic EPDM rubber rated from -81 F to 275 F, with very good abrasion resistance, tensile strength and memory, flame resistant and moisture resistant, and good resistance to ozone, sunlight and aging. That temperature span and the aging resistance are what matter on a cold-storage vestibule or a sun-exposed exterior leaf, where an insert has to keep its memory through repeated compression cycles. The Cal-Royal PG-601 uses a vinyl insert in its aluminum channel, which is the other common insert material for interior commercial perimeter gasketing.
14) If I need to seal the gap at the bottom of the door, will a perimeter seal do it?
No. The NGP 137NA is a perimeter seal, meaning it addresses the head and the two jambs of the frame, and it is furnished in sets sized to the opening: 36 inch x 84 inch, 36 inch x 96 inch, and 72 inch x 84 inch, where the first figure is the head and the second the jamb legs. The bottom of the door is a separate part, a door bottom or door shoe applied to the door itself. The Cal-Royal PG-601 is likewise an aluminum channel perimeter gasketing, so substituting it does not change that; a full opening needs the perimeter seal plus a bottom seal.
15) What finish does the NGP 137NA perimeter seal come in, and will it match aluminum storefront and hollow metal frames?
One finish: satin aluminum clear anodized. That is the same finish family as standard aluminum storefront framing, so it reads as a match on glass front and aluminum entrances. On a painted hollow metal frame it shows as a bright aluminum line at the stop rather than blending in, which is normal for commercial gasketing and is what most institutional specs call for anyway.
