NGP 139SS-84 – Frequently Asked Questions

1) Is the NGP 139SS astragal stainless steel or aluminum?
Type 304 stainless steel, with a brushed #4 finish (US32D, 630). That is the reason to pick it over an aluminum astragal: 304 holds up to corrosion in wet, coastal, or wash-down areas, and the #4 brush matches the 630 satin stainless trim already on most commercial openings. If your other hardware is aluminum or painted, an aluminum astragal like the Cal-Royal EAST-501 is the closer visual match.
2) Can I get the NGP 139SS astragal lead-lined for an X-ray room?
Yes. A 1/16 inch thick lead insert is available on the 139SS when you specify Lead-Lined at time of order, which is what healthcare and imaging suites use to close the radiation leak path at the meeting stile of a pair. The same insert adds mass for sound. Standard 139SS has no lead in it, so the lead-lined call-out has to be made on the order.
3) What is the difference between a full-height astragal like the NGP 139SS and a short lock astragal?
Two different jobs. The 139SS runs the full height of the leaf at 84 or 96 inches and seals the whole meeting stile gap on a pair of doors. A lock astragal such as the Trimco 5001 or the 5002 (1-9/16 x 6 inches) is a short piece that only covers the latch area to block a knife or shim attack at the lock. If you want light, air, and sight-line blocked top to bottom, use the full-height astragal; if you only need the latch protected, the short one is less material on the door.
4) What is the difference between the NGP 139SS astragal and the Trimco 5001 lock astragal?
They solve different problems on a double door. The NGP 139SS is a Type 304 stainless steel astragal in a brushed #4 finish (US32D, 630) that runs the height of the door in 84 inch and 96 inch lengths to close the gap between the two leaves. The Trimco 5001 is a stainless steel lock astragal, a short piece used with mortise or cylindrical locks to cover the lock area rather than seal the full meeting stile. If the goal is a full-height seal, the 139SS is the full-length part; if the goal is covering the latch region on a pair with a mortise or cylindrical lock, the 5001 is the lock astragal.
5) What astragal should I use on a fire-rated pair of doors instead of a stainless steel astragal?
The Pemko 369 split astragal seal is the fire-rated option in aluminum, with a pile brush insert and a 13/32 inch by 11/32 inch profile. A split astragal mounts a half on each leaf so both doors stay independently operable. The NGP 139SS is a Type 304 stainless steel astragal with a brushed #4 finish (US32D, 630) chosen for corrosion resistance and appearance. When the opening is a labeled fire pair, specify the Pemko 369.
6) My double doors both need to open independently. Will a one-piece astragal work, or do I need something else?
A one-piece astragal such as the NGP 139SS mounts to one leaf and overlaps the other, which establishes an active and inactive leaf. When both leaves must swing freely, use a split astragal instead: the Pemko 369 split astragal seal with pile brush insert puts a half on each door. The Pemko 300 Series adjustable astragal with self-adjusting pile brush is the other double-door seal in this family. Confirm which leaf carries the hardware before ordering, since that decides which style suits the opening.
7) Do I need to buy screws separately for the NGP 139SS astragal?
No. The 139SS ships with #10 x 3/4 inch sheet metal screws for mounting. On a hollow metal door those go straight into the door face; on a wood door you may want to swap to a wood screw of the same gauge.
8) Will the NGP 139SS astragal match the 630 satin stainless hardware already on my doors?
Yes. The 139SS carries a brushed #4 finish, which is the same thing as US32D and BHMA 630, so it lines up with the satin stainless push plates, pulls, and exit device trim commonly used across a facility. That makes it a straight match when you are standardizing openings rather than mixing finishes leaf to leaf.
9) Is there an astragal with a brush or vinyl seal instead of a bare metal astragal?
Yes, two different sealing methods. The Pemko 300 Series is an adjustable astragal with a self-adjusting pile brush for double doors, which lets the seal take up an uneven meeting stile. The Cal-Royal EAST-501 is an aluminum T-astragal with a vinyl insert for double doors, where the vinyl leg does the sealing. The NGP 139SS is Type 304 stainless steel with a brushed #4 finish (US32D, 630) and ships with #10 x 3/4 inch SMS fasteners. Choose the brush or vinyl versions when the gap needs a compliant seal, and the 139SS when a solid stainless meeting-stile cover is what the specification calls for.
10) I need an astragal for a wet or corrosive area such as a kitchen or a coastal loading dock. Which one holds up?
The NGP 139SS is built from Type 304 stainless steel specifically for corrosion resistance in commercial environments, with a brushed #4 finish (US32D, 630) that keeps a uniform appearance. The aluminum alternatives are the Cal-Royal EAST-501 T-astragal with vinyl insert and the Pemko 369 split astragal seal at 13/32 inch by 11/32 inch. Where washdown, humidity, or salt air is the concern, the stainless 139SS is the corrosion-resistant construction of the group.
11) Is the NGP 139SS astragal rated for commercial use or is it a residential part?
Commercial. NGP builds the 139SS for office buildings, schools, hospitals, retail, warehouses, multi-tenant residential, and government facilities, and the 304 stainless with a #4 brush is specified for that kind of traffic and cleaning regime.
12) What does the SNB option on the NGP 139SS astragal mean when ordering?
SNB is an ordering configuration you call out on the 139SS for installations that need it. Standard 139SS ships without it, so if your spec calls for SNB it has to be stated on the order rather than assumed.
13) Can a door shoe be used in place of an astragal on a pair of doors?
No. A door shoe seals the bottom of a single door leaf against the threshold, while an astragal seals the vertical gap where two leaves meet. The Cal-Royal EAST-501 is a T-astragal with vinyl insert for double doors and is the double-door part despite its series name; the NGP 139SS is the stainless steel astragal for the same vertical meeting-stile gap, in 84 inch and 96 inch lengths. For the bottom of the door you need a separate door bottom or shoe.
