NGP 159MA 84 – Frequently Asked Questions

1) Will one piece of NGP 159MA 84 inch seal do a whole door frame, or do I need more than one?
One 84 inch piece covers one leg. A standard 7 foot opening needs two 84 inch pieces for the hinge and strike jambs plus a head piece cut from another length, so plan on ordering by the leg, not by the opening. The 159MA runs up to 144 inches maximum available length, so a single longer piece can be cut down for the head if you would rather not splice.
2) Will an NGP 159MA magnetic door seal hold up on an exterior door in winter?
The 159MA is rated 0 F to 140 F. Below zero it is outside its stated operating range, so in climates that regularly run subzero it belongs on interior or vestibule openings rather than a fully exposed exterior door. In the 0 to 140 F band it handles exterior use, and the vinyl is moisture resistant with an anodized aluminum retainer that will not corrode like a mill or painted steel one.
3) Should I use a magnetic seal or a standard compression gasket on my commercial doors?
Pick by door material and by how tight you need it. A magnetic seal like the 159MA gives the tightest close on a steel door because the magnet actively pulls the vinyl into contact, which also means less drag on the closer than an over compressed bulb gasket. It needs ferrous material to work. A channel gasket with a vinyl insert, like the Cal-Royal PG-601, seals by compression instead and does not care what the door is made of, so it is the fallback for aluminum, fiberglass, or wood door faces.
4) What is the difference between the NGP 159MA magnetic seal and Cal-Royal PG-601 perimeter gasketing?
Both are perimeter seals mounted to the frame stop, but they seal by different means. The NGP 159MA seals with a magnet encased in gray vinyl carried in an aluminum alloy 6063 T5 temper extrusion, so contact is made by magnetic attraction to a steel door face. The Cal-Royal PG-601 is an aluminum channel perimeter gasketing with a vinyl insert, which seals by compression against the door as it closes. On a hollow metal door where a magnet has steel to grab, the 159MA holds contact without relying on door pressure; on aluminum, wood, or fiberglass doors that give a magnet nothing to pull against, the compression vinyl insert of the PG-601 is the seal that still works.
5) Can Cal-Royal PG-601 gasketing be used in place of an NGP 159MA magnetic seal on a wood door?
Yes, and on a wood door it is the more direct fit. The NGP 159MA relies on a magnet encased in gray vinyl to pull the seal against the door face, which requires a ferrous door for the magnet to act on. The Cal-Royal PG-601 uses an aluminum channel with a vinyl insert that compresses against whatever the door is made of, so the door material does not affect how it seals. Both mount to the frame as perimeter gasketing, so the location of the seal on the opening does not change; what changes is whether the seal depends on the door being steel.
6) Can the NGP 159MA magnetic weatherstripping be adjusted after it is screwed on?
Yes, and that is the point of the slotted screw holes. Back the fasteners off, slide the retainer in or out to change how hard the magnet meets the door, and retighten. That matters on a door that has settled or a frame that is not perfectly plumb, because a magnetic seal only performs where it makes continuous contact. It ships with #6 x 3/4 inch stainless steel sheet metal screws.
7) Do I need to buy screws with the NGP 159MA, or is mounting hardware included?
Fasteners come with it. Each piece includes #6 x 3/4 inch stainless steel sheet metal screws, so nothing extra is needed for a normal hollow metal or wood frame. Stainless matters on exterior openings where a plated screw head would rust and streak the frame.
8) Is Cal-Royal PG-601 a door shoe or a perimeter seal?
The Cal-Royal PG-601 is aluminum channel perimeter gasketing with a vinyl insert, so it treats the head and jambs of the opening. Buyers sometimes assume from the Door Shoes Series grouping that it addresses the bottom of the door, but a door shoe and a perimeter gasket are not interchangeable parts of an opening. The NGP 159MA magnetic seal covers the same head and jamb perimeter, in a standard 84 inch length with lengths available up to 144 inches. Neither part seals the door bottom, so a sweep or automatic door bottom is a separate item on the same opening.
9) Which perimeter seal holds up better in a cold entry vestibule, the NGP 159MA or the Cal-Royal PG-601?
The NGP 159MA is rated for service from 0 F to 140 F and uses a thermoplastic PVC polymer formulated with a bio-based plasticizer, with the extrusion in aluminum alloy 6063 T5 temper and an anodized aluminum finish. That stated temperature range is what a facility buyer specifying for an unconditioned vestibule or a loading corridor should size against. The Cal-Royal PG-601 pairs an aluminum channel with a vinyl insert in the same general construction approach, aluminum carrier plus a polymer sealing element. Where the two differ is the sealing action, magnetic contact on the 159MA against a compression insert on the PG-601.
10) What is the NGP 159MA seal made of, and will it hold its shape long term?
The retainer is aluminum alloy 6063 with a T5 temper, the standard extrusion alloy for architectural trim, anodized for the finish. The seal itself is thermoplastic PVC using a bio based plasticizer. Plasticizer is what keeps vinyl flexible, and the bio based formulation is the reason this one is specified on sustainable and LEED oriented jobs where conventional phthalate vinyl is a problem.
11) What finish does the NGP 159MA come in, and will it match my existing aluminum frames?
Anodized aluminum is the only finish the 159MA is offered in. That is a clear satin aluminum tone, so it reads as a match against mill finish or clear anodized storefront and hollow metal frames painted in aluminum tones. On dark bronze or painted frames it will contrast, and the visible part is the magnet strip itself, which is gray vinyl.
12) Is the NGP 159MA magnetic seal suitable for a hospital or school corridor door?
It is a commercial rated product and is used in healthcare, educational, office, retail, industrial, government, and multi tenant residential buildings. The flame resistant and moisture resistant vinyl plus the stainless fasteners suit high traffic institutional corridors, and buying one profile across a facility keeps the maintenance stock down to a single part number and one screw size.
