NGP 185PDKB-72 – Frequently Asked Questions

1) How long is each piece of the NGP 185PDKB perimeter seal, and how many do I need for one door?
It comes in a 72 inch length. A perimeter seal runs the head and both jambs of the frame, so a single 72 inch piece does not do a whole opening on its own: a typical 3070 opening is 36 inches across the head and 84 inches up each jamb, which means you are cutting from more than one piece per door. Order by total linear footage of frame you are sealing, not by door count.
2) Does the NGP 185PDKB go on the door or on the frame?
On the frame. A perimeter seal mounts to the head and jambs of the frame stop and the pile bridges the gap to the door face, which is why it works on both swing directions and why it does not interfere with the door edge, hinges, or lock hardware. It seals the perimeter only, so the gap under the door still needs a separate door bottom or sweep.
3) What is an equivalent to the NGP 185PDKB perimeter seal from another manufacturer?
The closest cross-brand equivalent is the Cal-Royal PG-601, an aluminum channel perimeter gasketing with a vinyl insert. Both are aluminum-channel perimeter seals applied to the head and jambs of a commercial opening; the difference is the seal medium carried in the channel. The NGP 185PDKB carries gray polypropylene pile in an aluminum alloy 6063 T5 channel with a dark bronze finish, rated 32 F to 275 F. The PG-601 carries a vinyl insert. For a property manager matching what is already on adjacent doors, the pile and the vinyl read differently at the frame and wear differently against a door edge, so confirm which medium the existing openings use before mixing the two across a building.
4) What is the NGP 185PDKB perimeter seal made of, and will it hold up on an exterior commercial door?
Aluminum alloy 6063 in T5 temper for the carrier, with a gray polypropylene pile as the sealing element and a dark bronze finish on the metal. The 6063-T5 extrusion is the same alloy family used for commercial door frames and trim, so it corrodes far less than a steel carrier on a weather-exposed opening, and polypropylene pile does not harden or crack the way a vinyl bulb can in cold. It is a commercial-grade product, not a residential foam or adhesive strip.
5) Can I use pile weatherstripping like the NGP 185PDKB on a door that gets hot, such as a mechanical room or a door in direct sun?
The 185PDKB perimeter seal is rated from 32 F to 275 F, so heat is not the limiting factor on a mechanical room, boiler room, or a west-facing exterior door that bakes all afternoon. The low end of that range is 32 F, which is the figure to weigh if you are sealing a walk-in cooler or a freezer vestibule rather than an exterior entrance.
6) Should I use a pile perimeter seal or a vinyl insert seal on a commercial door?
It depends on how the opening moves and how hot it gets. Pile, like the gray polypropylene in the NGP 185PDKB, sweeps against the door face and tolerates a door that is racked or out of plumb without binding, and it is rated for service from 32 F to 275 F. A vinyl insert seal such as the Cal-Royal PG-601 compresses against the door instead of sweeping, which gives a tighter contact line on a well-hung door. An HVAC or general contractor chasing air infiltration on a door that already drags will usually take the pile; a contractor sealing a square, well-adjusted opening has both options open. Both mount as an aluminum channel around the head and jambs, so the frame prep is the same either way.
7) Can a door shoe be used in place of the NGP 185PDKB perimeter seal?
No. A door shoe seals the bottom of the door against the threshold and mounts to the door itself; the NGP 185PDKB seals the head and jambs and mounts to the frame. They cover different parts of the same opening and a complete weatherseal job typically uses both. Note that the Cal-Royal PG-601, despite being an aluminum channel perimeter gasketing with a vinyl insert, sits in Cal-Royal's Door Shoes Series, so do not read the series name as meaning it replaces a bottom seal either. If you are sealing all four sides, plan on a perimeter seal for the head and jambs plus a separate bottom seal or automatic door bottom.
8) Will dark bronze gasketing match the rest of the hardware on my building's doors?
The 185PDKB carries a dark bronze finish on the aluminum, which is the standard pairing for openings already running dark bronze or oil-rubbed door hardware, storefront, and frames. If you are standardizing across a fleet of doors, note that the pile itself is gray regardless of the metal finish, so the visible edge at the stop reads bronze with a gray pile line.
