NGP 103NDKB-36 – Frequently Asked Questions

1) What lengths does the NGP 103NDKB perimeter seal come in, and how do I cover a full door opening?
The 103NDKB dark bronze perimeter seal is sold in 36, 48 and 72 inch lengths. A standard single opening takes one head piece plus two jamb pieces, so most installers pair a 36 or 48 inch length across the head with two 72 inch lengths down the jambs. Order per piece and cut to fit the frame.
2) Can I adjust the NGP 103NDKB seal after it is installed if the door does not close tight?
Yes, and that is the main reason to pick this one. The 103NDKB has adjustment screws on 10 inch centers, so you slide the seal in or out against the door face to tune compression without pulling the fasteners and re-drilling the frame. Useful on doors that have settled or on frames that are not perfectly plumb.
3) Will this NGP perimeter seal hold up on an exterior door in a cold climate or on a hot loading dock?
The seal is rated from -81 F to 275 F, which covers any exterior opening in North America plus mechanical and boiler room doors. The EPDM foam is flame resistant, moisture resistant and has good resistance to ozone, sunlight and aging, so direct sun exposure on a south-facing entrance is not a problem.
4) Is the NGP 103NDKB certified to a standard I can put on a submittal?
It is BHMA certified to the ANSI/BHMA A156.22 performance tests for heat and cold. That is the gasketing and edge seal standard, so it is the reference a spec writer or facility procurement group will be looking for on a perimeter seal submittal.
5) Does the NGP 103NDKB seal the bottom of the door too, or do I still need a door sweep?
Perimeter seal only. The 103NDKB mounts to the head and the two jambs of the frame and does nothing about the gap under the door. To close the opening you still need a door bottom, sweep or automatic door bottom, plus a threshold on an exterior opening. Budget those as separate line items on the job.
6) What is the difference between the NGP 103NDKB perimeter seal and the Cal-Royal PG-601 gasketing?
Both are aluminum channel perimeter gasketing for commercial door frames, but they differ in the sealing element and how the seal is set. The NGP 103NDKB uses a synthetic EPDM rubber in a polypropylene thermoplastic matrix closed cell elastomeric foam carried in an aluminum alloy 6063, T5 temper channel, and it has adjustment screws on 10 inch centers so the seal can be moved in or out against the door without pulling the channel off the frame and re-drilling. The Cal-Royal PG-601 is an aluminum channel perimeter gasketing with a vinyl insert, so the sealing element is vinyl rather than EPDM foam and the channel is fixed once mounted. If the opening is out of square or the door has settled, the adjustable NGP channel lets you tune the contact after mounting; if the frame is true and you just need a straight replacement gasket, the fixed vinyl channel covers it.
7) I need perimeter gasketing that will hold up to extreme heat and cold - which one should I spec?
The NGP 103NDKB is the one written for temperature extremes. It is rated for service from -81 F to 275 F and is BHMA certified to the ANSI/BHMA A156.22 performance tests for heat and cold, with flame resistance, moisture resistance and good resistance to ozone, sunlight and aging. That combination is aimed at exterior and unconditioned openings - warehouse and industrial doors, government and municipal buildings, healthcare and school exteriors. The Cal-Royal PG-601 is an aluminum channel perimeter gasketing with a vinyl insert, a conventional choice for interior and sheltered openings where extreme temperature swings and direct sun exposure are not the driving factor.
8) Does the NGP 103NDKB perimeter seal come with fasteners, or do I need to buy screws separately?
Fasteners are included. The 103NDKB ships with #6 x 3/4 inch or #6 x 1-1/2 inch stainless steel sheet metal screws, so a hollow metal or wood frame install needs nothing beyond a drill and the seal itself.
9) What is the NGP 103NDKB actually made of, and will it corrode on an exterior frame?
The retainer is aluminum alloy 6063 in T5 temper, the same extrusion alloy used for commercial storefront, with a dark bronze finish. The sealing element is synthetic EPDM rubber in a polypropylene thermoplastic matrix, closed cell elastomeric foam. Closed cell means it does not wick water, and the aluminum plus stainless screws keep the assembly corrosion resistant on an exterior opening.
10) What is the difference between an adjustable perimeter seal and a plain vinyl insert gasket?
Two different tools. The NGP 103NDKB is an adjustable seal: the aluminum retainer stays fastened while screws on 10 inch centers move the seal to set compression, which is what you want on doors that warp, settle, or need a tight seal for smoke, sound or conditioned air. A fixed vinyl insert gasket like the Cal-Royal PG-601 aluminum channel perimeter gasketing seats the insert in the channel with no adjustment, which is simpler and quicker where the frame is true and the gap is consistent. If you expect to come back and re-tune the opening, buy the adjustable version.
11) Is the Cal-Royal PG-601 a drop-in replacement for an NGP 103NDKB seal?
Treat them as alternates rather than a drop-in swap. Both are aluminum channel perimeter gasketing that mounts to the frame stop, so either can weatherize the same head and jamb opening, but the NGP 103NDKB is an adjustable channel with screws on 10 inch centers and an EPDM foam insert, while the Cal-Royal PG-601 carries a vinyl insert in a fixed aluminum channel. The channel profiles and insert kerfs are not interchangeable, so an existing NGP channel will not accept a PG-601 insert and vice versa. If you are only replacing a worn gasket and leaving the channel on the frame, stay with the matching brand's insert; if you are replacing the whole assembly, either can be specified for the opening. The 103NDKB also ships with #6 x 3/4 inch or #6 x 1-1/2 inch stainless steel SMS fasteners, so no separate fastener line is needed for that one.
12) Will perimeter gasketing seal the bottom of the door, or do I need something else there?
Perimeter gasketing seals the head and the two jambs - it mounts to the frame stop and closes the gap around the door's perimeter. It does not address the gap between the door bottom and the threshold. The NGP 103NDKB comes in 36 inch, 48 inch and 72 inch lengths, which are cut to suit the jamb and head runs on a standard opening, and it is covered in the NGP Gasketing and Automatic Door Bottoms catalog alongside the bottom-of-door products. For the sweep or door bottom, look to a door shoe or sweep product - the Cal-Royal PG-601 belongs to Cal-Royal's Door Shoes series, which is where the bottom-of-door items live. Budget for both lines if you are weatherizing a full exterior opening.
13) I manage a portfolio and want one perimeter seal I can standardize on across buildings - which is the better fleet choice?
For standardizing across mixed openings, the NGP 103NDKB has the wider tolerance band. It is a commercial-rated seal, BHMA certified to ANSI/BHMA A156.22 for heat and cold, rated -81 F to 275 F, and the adjustment screws on 10 inch centers mean one part number works on doors that have settled or frames that are slightly out of square without having to re-drill the channel. It is offered in 36 inch, 48 inch and 72 inch lengths, so head and jamb runs on standard openings can be covered from a short stock list. The Cal-Royal PG-601 is an aluminum channel gasketing with a vinyl insert, a simpler fixed-channel design suited to uniform interior openings where the frames are true and one setting fits them all.
14) Will the dark bronze finish match the rest of my hardware, or should I use a different perimeter seal?
The 103NDKB is finished in dark bronze, which reads with oil-rubbed bronze and dark anodized frames rather than with clear aluminum or brass. If the openings across your property are clear aluminum storefront, put a mill or clear anodized seal on those rather than mixing. For a fleet standardization, pick one finish and run it across every opening so the parts room stocks a single line.
15) Is this NGP seal meant for commercial openings or residential doors?
It is a commercial-rated product. NGP lists the 103NDKB as commercial, and the material package (6063-T5 aluminum, EPDM foam, stainless screws, A156.22 certification) is built for the traffic in offices, schools, healthcare, retail, warehouses, multi-tenant residential and municipal buildings. It works fine on a house door, but you are paying for commercial durability.
