NGP 170NA-36 – Frequently Asked Questions

1) What lengths does the NGP 170NA perimeter seal come in, and how do I cover a standard opening?
The 170NA neoprene perimeter seal is stocked in 36, 48, 72 and 84 inch lengths. A typical single opening takes two head-and-jamb sets: the 36 or 48 inch piece across the head and the 72 or 84 inch pieces down each jamb. For a 7 foot door you want the 84 inch jamb lengths so you are not splicing partway down the strike side.
2) Does the NGP 170NA come with fasteners or do I need to buy screws separately?
Screws are included. The 170NA ships with #6 x 3/4 inch stainless steel sheet metal screws, and the housing is punched with slotted holes so you can shift the seal in or out against the door face before you set them. You will still need to supply anything required to splice or miter corners at the head and jamb junction.
3) Will this door gasket hold up in a cold climate or on a hot west-facing entrance?
The 170NA is rated for service from -20 F to 200 F, and it is BHMA certified to the ANSI/BHMA A156.22 heat and cold performance tests. The seal element is a chloroprene and EPDM blend, which is why it resists ozone, sunlight and aging rather than going hard and cracking after a couple of seasons on a sun-beaten south or west elevation.
4) Is the NGP 170NA a fire door gasket or a smoke seal?
Treat it as a weather and perimeter seal, not a listed fire or smoke gasket. What the 170NA carries is BHMA certification to ANSI/BHMA A156.22 for heat and cold resistance, with flame resistant and moisture resistant construction. If your opening needs a labeled smoke or fire rated gasket for a rated assembly, specify a product carrying that listing.
5) What is the difference between the NGP 170NA perimeter seal and the Cal-Royal PG-601 perimeter gasketing?
Both are aluminum channel perimeter seals for commercial door frames, but the sealing element differs. The NGP 170NA uses a synthetic rubber polymer blend of Chloroprene and EPDM in an aluminum alloy 6063 T5 housing with an anodized finish, and it hides the screw heads under a snap-on cover for a clean face. The Cal-Royal PG-601 is an aluminum channel perimeter gasketing with a vinyl insert. If you want a neoprene/EPDM seal element and concealed fasteners, the 170NA is the one to specify; if a vinyl insert in an aluminum channel meets the job, the PG-601 covers that.
6) I need a perimeter seal that meets ANSI/BHMA A156.22 - which one should I specify?
Specify the NGP 170NA. It is BHMA certified to ANSI/BHMA A156.22 performance tests for heat and cold, with an operating range of -20 F to 200 F, which is what institutional and government specifications typically call out. The Cal-Royal PG-601 is an aluminum channel perimeter gasketing with a vinyl insert and is the alternative when a certified seal is not a requirement of the drawing.
7) Will the screw heads show after I install this weatherstrip?
No. The 170NA uses a snap-on cover that hides the screw heads once the housing is fastened, so the finished jamb shows a clean anodized aluminum face. That is the practical difference between this and an exposed-fastener gasket: on a lobby or tenant entry where the stop is at eye level, the fasteners disappear.
8) What is the housing made of, and will it corrode on an exterior door?
The housing is 6063 T5 temper aluminum alloy with an anodized finish. That alloy and finish combination is the standard for exterior extruded trim because the anodic coating resists corrosion without painting, so it is appropriate on entrances exposed to rain and road salt spray.
9) Should I use a perimeter seal like this or an aluminum channel gasket with a vinyl insert?
Both mount to the stop and seal the head and jambs, but the sealing element differs. The 170NA uses a synthetic rubber blend of chloroprene and EPDM, chosen for abrasion resistance and memory retention, so it recovers its shape after repeated closings on high traffic entries. The Cal-Royal PG-601 is an aluminum channel perimeter gasketing with a vinyl insert, a common choice where a vinyl bulb is the accepted spec. If your drawing calls for neoprene specifically, the 170NA is the one that matches.
10) Is the Cal-Royal PG-601 a door shoe or a perimeter seal? I do not want to order the wrong thing.
The Cal-Royal PG-601 is perimeter gasketing - an aluminum channel with a vinyl insert that mounts to the head and jambs of the frame, even though Cal-Royal groups it in their Door Shoes Series. A door shoe mounts to the bottom edge of the door itself and does a different job. If you are sealing the head and jamb perimeter, the NGP 170NA neoprene perimeter seal and the PG-601 are the two to look at; neither one replaces a door bottom or a threshold.
11) For an exterior door in a cold climate, is neoprene or a vinyl insert the better perimeter seal?
For hard winters, the NGP 170NA is the one built for it: its Chloroprene and EPDM compound is rated from -20 F to 200 F, is tested to BHMA A156.22 for heat and cold, and resists ozone, sunlight and aging with good memory retention so it keeps its seal after repeated compression. The Cal-Royal PG-601 uses a vinyl insert in an aluminum channel, which is the more common choice on interior and sheltered openings. The 170NA comes in 36, 48, 72 and 84 inch lengths so you can pick head and jamb pieces off the same part.
12) Can I use the NGP 170NA on interior doors, or is it only for exterior openings?
It is built as a commercial-grade product and nothing stops you using it on an interior opening where you want sound and air control at the head and jambs. The design intent is exterior and climate-controlled openings, office and retail entrances, school exterior doors, healthcare climate separation, and multi-tenant entries, where the -20 F to 200 F range and weather resistance actually earn their keep.
