NGP 122NDKB-36 – Frequently Asked Questions

1) What lengths does the NGP 122NDKB neoprene sponge seal come in, and how do I cover a standard commercial opening?
The 122NDKB is sold in 36, 60, 72, 84 and 96 inch lengths. For a typical single opening you take one piece across the head and one down each jamb, so a 36 inch head piece plus two 84 inch jamb pieces covers a 3ft x 7ft door. Cut the stock down on site rather than piecing short lengths together mid-run.
2) Will this NGP door seal hold up on an exterior door in a cold climate?
Yes. The seal's EPDM element is rated from -50 F to 275 F and is BHMA certified to the ANSI/BHMA A156.22 performance tests for heat and cold. It also resists ozone, sunlight and aging, and the housing is aluminum alloy 6063 T5 for corrosion resistance, so it is built for exterior perimeter use, not just interior sound or light gasketing.
3) Do I need to buy fasteners separately to install the NGP 122NDKB perimeter seal?
No, screws come with it. Each piece is furnished with #6 x 3/4 inch stainless steel sheet metal screws, and the holes in the aluminum housing are slotted so you can shift the seal in or out against the door face before final tightening. That slotting is what lets you tune compression after the door is hung.
4) What is the difference between the NGP 122NDKB neoprene sponge seal and the Cal-Royal PG-601 perimeter gasketing?
Both are aluminum channel perimeter seals for door frames, but the sealing element differs. The NGP 122NDKB uses a synthetic EPDM rubber in a polypropylene thermoplastic matrix, closed cell elastomeric foam, rated from -50 F to 275 F and BHMA certified to ANSI/BHMA A156.22 heat and cold performance tests, in an aluminum alloy 6063 T5 temper housing with a dark bronze finish. The Cal-Royal PG-601 is an aluminum channel perimeter gasketing with a vinyl insert. If the opening sees temperature extremes or you need the A156.22 certification on the submittal, the 122NDKB carries that rating; where a plain vinyl bulb insert satisfies the spec, the PG-601 is the alternative channel gasket.
5) Is the dark bronze finish on this NGP seal going to match my existing bronze door frames?
The 122NDKB is the dark bronze version of NGP's neoprene sponge seal, which is the usual companion to dark bronze anodized aluminum storefront and hollow metal frames. All five lengths carry the same dark bronze housing, so a building standardizing across many openings gets a consistent look whether the piece is a 36 inch head or a 96 inch jamb.
6) What is the difference between an EPDM sponge perimeter seal and a vinyl bulb gasket like the Cal-Royal PG-601?
Both are aluminum channel perimeter gaskets that mount to the frame stop. The NGP 122NDKB uses a closed cell microcellular EPDM sponge element rated -50 F to 275 F with stated abrasion resistance and memory, which is what keeps it sealing after repeated closings on a high traffic door. The Cal-Royal PG-601 is an aluminum channel with a vinyl insert. Vinyl inserts are common on interior and light duty exterior work; the EPDM sponge is the choice where temperature swing and long-term compression set are the concern.
7) Can I use this NGP neoprene sponge seal on a fire rated door opening?
The 122NDKB gasket material is described as flame resistant and is BHMA certified to ANSI/BHMA A156.22 for heat and cold performance. Gasketing on a fire rated opening has to be a listed product for that assembly, so match the seal to what is called out on the door and frame labels before installing it on a rated opening.
8) Will the Cal-Royal PG-601 seal the bottom of the door like a door shoe?
The Cal-Royal PG-601 is catalogued in Cal-Royal's Door Shoes Series but is described as aluminum channel perimeter gasketing with a vinyl insert, meaning it mounts to the frame head and jambs. The NGP 122NDKB is likewise perimeter gasketing that mounts to the frame stop. Neither one seals the gap under the door leaf - that requires a door bottom or door shoe, so plan on a separate bottom seal in addition to whichever perimeter gasket you choose.
9) I need weatherstripping for an exterior door in a cold climate - NGP 122NDKB or Cal-Royal PG-601?
For exposure to weather extremes, the NGP 122NDKB states a service range of -50 F to 275 F with flame-resistant and moisture-resistant properties and good resistance to ozone, sunlight and aging, and it is BHMA certified to ANSI/BHMA A156.22 for heat and cold. The Cal-Royal PG-601 is a vinyl insert perimeter gasket in an aluminum channel, a simpler construction suited to interior and light-duty perimeter sealing. The 122NDKB also ships with #6 x 3/4 inch stainless steel sheet metal screws and slotted holes so the seal can be adjusted against the door face after hanging.
10) Can I use the Cal-Royal PG-601 as a substitute for NGP 122NDKB dark bronze seal on a bronze storefront?
Check the finish before you commit. The NGP 122NDKB is supplied in a dark bronze finish on its 6063 T5 aluminum housing, in lengths of 36, 60, 72, 84 and 96 inches, so head and both jambs of a standard opening can be cut from stock lengths in a matching finish. The Cal-Royal PG-601 is an aluminum channel perimeter gasketing with a vinyl insert; confirm its finish matches the surrounding bronze frame before substituting, since perimeter gasket is surface applied and visible on the stop.
11) Is this NGP seal meant for commercial doors or will it work on a house?
It is specified as commercial gasketing. The aluminum 6063 T5 housing and screw-applied mounting suit hollow metal and aluminum frames in offices, schools, healthcare, retail and multi-tenant buildings. It will physically go on a residential door with a flat stop face, but the product is built and priced for commercial door frames rather than residential wood jambs with irregular stops.
