NGP 141NDKB 96 – Frequently Asked Questions

1) Can the NGP 141NDKB seal be adjusted after it's screwed to the frame?
Yes, and that's the point of the spring adjustable design. Adjustment screws sit on 10 inch centers, so you can dial in seal pressure against the door face without pulling the fasteners and re-drilling the mounting holes. Useful on frames that aren't perfectly plumb or doors that have settled.
2) Will this NGP perimeter seal hold up on an exterior door in a cold climate?
It's rated from -81 F to 275 F. The seal element is synthetic EPDM rubber in a polypropylene thermoplastic matrix with good resistance to ozone, sunlight and aging, and it's BHMA certified to ANSI/BHMA A156.22 heat and cold performance tests. That combination is what qualifies it for exterior openings rather than interior-only smoke or light gasketing.
3) What is the difference between the NGP 141NDKB perimeter seal and the Cal-Royal PG-601 gasketing?
Both are aluminum channel perimeter gasketing for commercial door frames, but the sealing element and the adjustment method differ. The NGP 141NDKB uses a spring-loaded synthetic EPDM rubber insert in a polypropylene thermoplastic matrix, with adjustment screws on 10 inch centers so the seal pressure can be fine-tuned after the housing is fastened, and it is certified to ANSI/BHMA A156.22 heat and cold performance tests. The Cal-Royal PG-601 is an aluminum channel perimeter gasketing with a vinyl insert. If the opening needs pressure that can be re-set later without moving the mounting holes, the spring adjustable 141NDKB is the one that does that; if a fixed vinyl bulb seal is acceptable, the PG-601 is the simpler channel.
4) What fasteners come with the NGP 141NDKB, and do they work in a hollow metal frame?
Stainless steel sheet metal screws are included, #6 x 3/4 inch or #6 x 1-1/2 inch. The short screws are the ones used into hollow metal; the longer length is there for wood frames where you need more bite. Stainless matters on an exterior opening where plated screws would rust-stain the bronze finish.
5) Is the NGP 141NDKB rated for commercial use or is it a residential weatherstrip?
Commercial. It's specified for office building entrances, school exterior doors, healthcare climate control, retail, industrial facilities, multi-tenant common areas and government buildings. The flame-resistant, moisture-resistant construction and BHMA certification are what separate it from residential foam or vinyl weatherstrip.
6) What's the difference between a spring adjustable perimeter seal and a plain vinyl insert gasket?
A fixed gasket like the Cal-Royal PG-601 aluminum channel uses a vinyl insert held in an extruded channel, so the seal compression is set by where you mount the channel. The NGP 141NDKB is spring loaded and keeps pressure on the door face as the door and frame move, and it can be re-tensioned at the adjustment screws later. For a door that gets heavy traffic or an opening that goes out of alignment, the adjustable type holds its seal longer; for a straightforward interior opening, the simpler channel-and-insert type is enough.
7) Does this NGP seal go on the door or the frame?
Perimeter seal of this type mounts to the frame, on the stop at the head and hinge and strike jambs, with the seal bearing against the door face. It handles the head and jambs only, so the bottom of the door still needs a separate door bottom or sweep and, on an exterior opening, a threshold.
8) Is vinyl or EPDM the better insert for an exterior door that sees sun and weather?
EPDM is the material specified for exposure. The NGP 141NDKB uses synthetic EPDM rubber rated from -81 F to 275 F with good resistance to ozone, sunlight and aging, plus flame-resistant and moisture-resistant construction, which is why it suits exterior entrances and high-exposure openings. The Cal-Royal PG-601 carries a vinyl insert in its aluminum channel. For an interior opening where the gasket is only controlling light, sound transfer or drafts between conditioned spaces, the vinyl-insert PG-601 channel covers the job.
9) Will the Cal-Royal PG-601 work as a door bottom in place of the NGP 141NDKB?
Neither one is a door bottom. The NGP 141NDKB is head and jamb perimeter gasketing that mounts to the frame stop, and the Cal-Royal PG-601 is likewise an aluminum channel perimeter gasketing. Cal-Royal groups the PG-601 in its Door Shoes series, which is a catalog grouping rather than a statement that the part seals the sill. Perimeter gasketing seals the three sides of the frame; the bottom of the door still needs a separate sweep, shoe or automatic door bottom to close that gap.
10) Is the dark bronze on this NGP seal a painted finish or anodized aluminum?
The housing is aluminum alloy 6063, T5 temper in a dark bronze finish. If you're matching a building standard, 6063-T5 extrusion is the same base stock used across commercial gasketing lines, so it sits well next to dark bronze door frames and closers on the rest of the opening.
11) I need gasketing that matches dark bronze hardware on the rest of the openings.
The NGP 141NDKB 96 is supplied in a dark bronze finish on a 6063-T5 aluminum alloy extrusion at 96 inches, which is the length that covers a standard commercial frame head or jamb leg, and it ships with #6 x 3/4 inch or #6 x 1-1/2 inch stainless steel sheet metal screws. The Cal-Royal PG-601 is an aluminum channel gasketing as well, so if the rest of a building is being standardized on one gasket profile, the two are the same basic mounting approach on the frame stop.
