NGP 139DKB-84 – Frequently Asked Questions

1) What is a lead-lined astragal for, and how do I order the NGP 139 that way?
The lead-lined version of the NGP 139 carries a 1/16 inch thick lead insert inside the astragal body, and it has to be called out as "Lead-Lined" when you order. Two reasons people specify it: radiation shielding at the meeting edge of a pair of doors, which is what an imaging or x-ray suite needs so the gap between leaves isn't a leak path, and sound dampening on a door where the astragal is the last soft spot. If you're ordering for a healthcare radiology opening, the lead-lined call-out is the one detail that gets missed most often, because the standard part looks identical.
2) Should I use a solid metal astragal or a gasketed astragal with a brush or vinyl seal on my double doors?
They solve different problems. The NGP 139 is solid aluminum, so it's the rigid closure piece that covers the gap between a pair of doors and gives the inactive leaf an edge to strike against, plus it's the one that takes a lead liner if you need shielding. It does not have a compressible seal in it. If what you're chasing is air, light, or smoke infiltration at the meeting stile, a gasketed astragal is the better call: the Pemko 300 Series is an adjustable astragal with a self-adjusting pile brush, the Pemko 369 is a split astragal seal with a pile brush insert, and the Cal-Royal EAST-501 is a T-astragal with a vinyl insert. Plenty of jobs use a solid astragal for the meeting edge and separate gasketing elsewhere on the frame.
3) My double doors have a mortise lock in the active leaf. Is the NGP 139 the right astragal?
Probably not, if the astragal has to clear the lock. The NGP 139 is a full-length solid astragal running 84 or 96 inches down the meeting edge, which is what you want on a pair with no lock crossing that line. Where a mortise or cylindrical lock is in play you want a lock astragal, a short piece that goes around the latch: the Trimco 5001 stainless steel lock astragal is made for mortise or cylindrical locks, and the Trimco 5002, at 1-9/16 x 6 inches, is for cylindrical locks. Some installers run both, a full-length astragal plus a lock astragal at the strike.
4) What is the closest alternative to the NGP 139DKB solid metal astragal if the double door opening needs a seal built into the astragal?
The NGP 139DKB is a solid metal astragal in aluminum alloy 6063 T5 temper with a dark bronze finish, supplied in 84 inch and 96 inch lengths with #10 x 3/4 inch SMS fasteners. If the opening calls for an astragal that carries its own seal element, the Cal-Royal EAST-501 is an aluminum T-astragal with a vinyl insert for double doors, and the Pemko 300 Series is an adjustable astragal with a self-adjusting pile brush for double doors. Both are the same part of the opening as the 139DKB, the meeting stile of a pair, with the sealing material carried in the astragal itself rather than the solid metal section.
5) Is a Trimco 5001 or 5002 lock astragal a substitute for an NGP 139DKB astragal?
No, those solve a different problem even though the word astragal appears in both. The NGP 139DKB is a full-height solid metal astragal in 84 inch and 96 inch lengths that runs the meeting stile of a pair of doors. The Trimco 5001 is a stainless steel lock astragal for use with mortise or cylindrical locks, and the Trimco 5002 is a stainless steel lock astragal measuring 1-9/16 inches by 6 inches for use with cylindrical locks. A 6 inch stainless piece at the lock is guarding the latch area, not running the height of the stile, so ordering one in place of a 139DKB leaves the rest of the meeting edge open.
6) For a fire-rated pair of doors, what astragal should be specified instead of the NGP 139DKB dark bronze?
The Pemko 369 split astragal seal is described as fire-rated aluminum with a pile brush insert and a 13/32 inch by 11/32 inch section. Split means it mounts as two halves, one on each leaf of the pair, rather than as the single solid metal section the NGP 139DKB provides. Where the drawing calls for a fire rating on the astragal itself, the 369 is the part to specify, and the 13/32 inch by 11/32 inch profile is a much smaller section than a full solid metal astragal, so confirm the meeting stile gap it has to cover before substituting.
7) What is the NGP 139DKB astragal made of, and will the finish hold up on an exterior door?
Aluminum alloy 6063 with T5 temper, finished in dark bronze. The 6063 T5 combination is what NGP uses for corrosion resistance on commercial openings, so it holds up on exterior and high-traffic doors. The dark bronze is an anodized-style aluminum finish, so it reads as a bronze-tone trim rather than mill aluminum if you're matching darker frames and door hardware.
8) Do I need to buy screws separately for the NGP 139DKB astragal?
No, fasteners come with it. Each piece ships with #10 x 3/4 inch sheet metal screws for mounting. That size is sized for the astragal into a hollow metal or wood door face. If you're going into an aluminum or a mineral-core door where a 3/4 inch SMS won't hold, plan on your own fasteners; nothing else about the mounting method changes.
9) What is the difference between a T-astragal like the Cal-Royal EAST-501 and the NGP 139DKB solid metal astragal?
The Cal-Royal EAST-501 is an aluminum T-astragal for double doors with a vinyl insert, so the T-shaped section overlaps the gap and the vinyl does the sealing against the opposite leaf. The NGP 139DKB is a solid metal astragal in aluminum alloy 6063 with T5 temper and a dark bronze finish, with no insert in the section, and it ships with #10 x 3/4 inch SMS fasteners. The 139DKB also offers an optional 1/16 inch lead insert for sound dampening and radiation shielding when Lead-Lined is specified, which is a capability the vinyl-insert T-astragal does not carry. For a healthcare or imaging opening that needs the lead, the two are not interchangeable.
10) If the pair of doors is out of alignment or the gap varies down the meeting stile, is the NGP 139DKB the right astragal?
A solid metal astragal like the NGP 139DKB holds a fixed section, so the gap it covers is whatever the fixed profile covers. Where the leaves are out of alignment, the Pemko 300 Series is an adjustable astragal with a self-adjusting pile brush for double doors, and the Pemko 369 split astragal seal carries a pile brush insert, both of which use brush to take up variation across the meeting edge. The 139DKB remains the choice where the opening wants a solid metal edge rather than a brush seal, including the Lead-Lined configuration with a 1/16 inch lead insert.
11) Is the NGP 139DKB astragal rated for commercial use or is it a residential part?
Commercial. The 139 is built for commercial openings, and the places it lands are office buildings, schools, hospitals, retail, industrial and warehouse space, multi-tenant residential, and government buildings. For a property manager standardizing across a portfolio, that matters mostly because the aluminum 6063 T5 body and the dark bronze finish are consistent piece to piece, so an astragal replaced on one building's doors matches the rest.
12) What is the SNB option on the NGP 139 astragal?
SNB is a special configuration NGP makes available on the 139 when you call it out at time of order. Like the lead-lined version, it isn't a stock variation you pick off a shelf, it's a specification you state. If your drawing calls for SNB, put it on the order explicitly.
13) We are standardizing astragals across a commercial building in stainless rather than bronze aluminum. What are the stainless options?
The Trimco 5001 and Trimco 5002 lock astragals are stainless steel; the 5001 is for use with mortise or cylindrical locks and the 5002 is 1-9/16 inches by 6 inches for use with cylindrical locks. Both are lock astragals covering the latch area rather than full-height meeting stile sections. The NGP 139DKB is aluminum alloy 6063 with T5 temper in a dark bronze finish and runs the full stile at 84 inches or 96 inches, so a stainless standard at the lock and a full-height astragal on the pair are two separate line items, not one replacing the other.
