NGP 135N-60 – Frequently Asked Questions

1) Will the NGP 135N perimeter seal work on an exterior commercial entrance in a cold climate?
Yes. The 135N is a commercial-grade perimeter seal, and its EPDM rubber sealing element is rated from -81 F to 275 F, so freeze-thaw cycling and summer heat on a sun-loaded entrance are both inside its range. It is BHMA certified to the ANSI/BHMA A156.22 performance tests for heat and cold, which is the gasketing standard an institutional spec will call out. The aluminum retainer is 6063 T5 alloy, and the rubber resists ozone, sunlight, and aging.
2) Does the NGP 135N mount to the door or to the frame?
It is a perimeter seal, so it fastens to the frame, on the stop, and the door closes against the rubber bulb. That is why it works on either a wood or a hollow metal frame and why handing is irrelevant to the order: you buy by length and cut. Fasteners are included, #6 x 3/4 inch stainless steel sheet metal screws, which is the right length to bite the stop without punching through a typical hollow metal jamb face.
3) Will a perimeter seal alone stop drafts under the door, or do I need something else?
A perimeter seal handles the head and both jambs only. The bottom of the door is a separate part: you still need a door bottom, a door shoe, or a threshold and sweep to close the gap at the sill. Plan on ordering the 135N for the three sides of the frame plus a bottom seal for the fourth, or you will have sealed the perimeter and left the biggest air path open.
4) What is a cross-brand equivalent to the NGP 135N perimeter seal?
The closest cross-brand counterpart is the Cal-Royal PG-601 aluminum channel perimeter gasketing. Both are aluminum-channel perimeter seals applied to the frame stop, and both are surface-applied gasketing rather than a door bottom. The difference is the sealing element: the NGP 135N uses a synthetic EPDM rubber in a polypropylene thermoplastic matrix, rated from -81 F to 275 F and BHMA certified to ANSI/BHMA A156.22 heat and cold performance tests, while the Cal-Royal PG-601 carries a vinyl insert. For an exterior opening where the seal sees full sun, ozone, and a wide seasonal swing, the EPDM element of the 135N is the one carrying a published temperature range and BHMA certification.
5) Can I adjust the NGP 135N after it is installed if the door is not sealing evenly?
Yes, and that is the practical reason to pick it. The mounting holes are slotted rather than round, so you can back the screws off and slide the seal in or out against the stop to take up a door that sits proud at the top or drags at the latch. On a door with a twisted slab or a frame that racked during install, that adjustment is what gets you a continuous seal without shimming the hinges.
6) Can the NGP 135N be used on a fire rated door opening?
The 135N is flame resistant and BHMA certified to the ANSI/BHMA A156.22 performance tests for heat and cold, which covers weather and smoke-type gasketing performance. Fire door assemblies are governed separately, and any gasketing on a labeled opening has to be the category listed for that assembly. Specify the 135N for weather and light sealing on commercial entrances; for a labeled fire door, confirm the gasketing category required by the door label before you set it.
7) Will the NGP 135N hold up on a high traffic door that gets slammed hundreds of times a day?
The sealing element is synthetic EPDM in a polypropylene thermoplastic matrix, chosen for abrasion resistance, tensile strength, and memory retention, meaning the bulb returns to shape after repeated compression instead of taking a set and leaving a gap. Backed by a 6063 T5 aluminum retainer, it is the right build for school, retail, and multi-tenant entrances rather than a foam tape seal that flattens out in a season.
8) Is vinyl-insert perimeter gasketing the same thing as an EPDM neoprene seal?
They fill the same slot on the frame but they are not the same material. Vinyl-insert gasketing, such as the Cal-Royal PG-601 aluminum channel perimeter gasketing, uses a vinyl sealing element. The NGP 135N uses synthetic EPDM rubber in a polypropylene thermoplastic matrix, chosen for abrasion resistance, tensile strength, memory retention, and resistance to ozone, sunlight, and aging, and it is flame resistant and moisture resistant. If a facility standard or a drawing calls out EPDM or neoprene specifically, a vinyl insert is a different material and should not be swapped in without confirming the spec.
9) Is the NGP 135N finish going to match aluminum storefront and clear anodized frames?
The 135N comes in a milled aluminum finish, which is the bare mill finish of the 6063 T5 extrusion. It reads as a light natural silver and sits closest to clear anodized aluminum, so it blends on storefront and aluminum entrance frames. On a dark bronze or painted hollow metal frame it will contrast, and a property manager standardizing a building front should expect a visible silver line on the stop.
10) Do I get the screws with the NGP 135N or do I have to supply my own fasteners?
Screws are included. Each 135N ships with #6 x 3/4 inch stainless steel sheet metal screws, so nothing else is needed to hang it on a wood or hollow metal frame. The stainless is what matters on an exterior opening, since plated steel screws in an aluminum retainer will corrode and streak the frame. Cutting is the only field work: a hacksaw or a miter saw with a non-ferrous blade takes the aluminum cleanly.
