Pemko 369DP-48 – Frequently Asked Questions

1) Will the Pemko 369 astragal seal a pair of doors that has no center mullion?
That is what a split astragal is for. The Pemko 369 mounts on the meeting stiles of a door pair, one half on each leaf, and the pile brush insert closes the gap between the leaves against draft, dust, moisture, fumes, light and sound. The aluminum profile is small, 13/32 inch wide by 11/32 inch high, so it takes up very little of the clearance between the doors. On a pair of fire doors, the requirements of NFPA 80 still govern how the pair is assembled.
2) Can I put the Pemko 369 split astragal on fire-rated doors?
Fire rated, and tested to UL 10C, the positive pressure fire test of door assemblies. The one condition the manufacturer attaches is on pairs: when the 369 goes on a pair of fire doors, the installation has to maintain the requirements of NFPA 80. Fire-rated door assemblies are one of the named applications for this seal, along with commercial office, institutional, healthcare, multi-family and government buildings.
3) I need an astragal that laps over the gap between the two doors. Is the Pemko 369 that part?
No. The 369 is a split seal profile, 13/32 by 11/32 inch, that carries a pile brush and sits on the meeting stiles. It does not lap one leaf over the other. If the opening needs an overlapping astragal, ZenSupply carries the NGP 176A 84, an overlapping astragal in anodized aluminum at 84 inches, and the NGP 139SP, a steel fire-rated door astragal with 3/4 inch overlap coverage. The NGP 109N is an overlapping astragal with a neoprene seal in an 84 inch length.
4) What is the closest alternative to the Pemko 369 astragal if the opening calls for a vinyl insert instead of a pile brush?
The Cal-Royal EAST-501 is an aluminum T-astragal with a vinyl insert made for double doors, and it is the nearest match when the specification calls for vinyl rather than brush. The Pemko 369 uses a pile brush insert in a 13/32 inch wide by 11/32 inch high aluminum profile; the brush wipes across the mating surface and reduces sliding friction while holding a continuous seal against draft, dust, moisture, fumes, light, and sound. A vinyl insert seals by compressing against the mating leaf instead, so it behaves differently on a pair that is opened and closed constantly versus a pair that stays latched. Both are aluminum-bodied astragals for a pair of doors, so the mounting surface is the same meeting stile in either case.
5) Are the Trimco 5001 and 5002 lock astragals a substitute for a Pemko 369 astragal?
No - they solve a different problem despite carrying the same word. The Trimco 5001 is a stainless steel lock astragal used 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. Those are short stainless pieces sized around the lock area of the meeting stile, as the 6 inch dimension on the 5002 shows. The Pemko 369 is a full-height aluminum split astragal with a pile brush insert, furnished in 48 inch and 84 inch lengths, that runs the meeting stile to seal against draft, dust, moisture, fumes, light, and sound. If the requirement is a continuous perimeter seal on a pair, a 6 inch lock astragal will not deliver it; if the requirement is protecting the lock area at the meeting stile, the Trimco pieces are what does that job.
6) What steel astragal can be used on a fire-rated pair instead of the aluminum Pemko 369?
The NGP 139SP is a steel fire-rated door astragal with 3/4 inch overlap coverage, and it is the steel-bodied option for a fire-rated pair. The Pemko 369 is an aluminum profile, 13/32 inch by 11/32 inch, carrying a pile brush insert, and it is tested to UL 10C for positive pressure fire test of door assemblies. The practical difference is substrate and seal method: the 139SP is a steel section with a 3/4 inch lap over the gap, while the 369 closes the gap with brush pile in an aluminum extrusion. On either one, pairs of fire doors have to be installed to the requirements of NFPA 80, and the astragal has to be listed for the specific door assembly it is going on, so match it to the door label before ordering.
7) Which Pemko 369 finish do I order to match the rest of my door hardware?
Two finishes on the 369: mill finish aluminum, ordered as 369AP, and dark bronze anodized aluminum, ordered as 369DP. Mill is the raw aluminum look that disappears against aluminum frames and storefront; dark bronze anodized is the one to pick where the frames, thresholds and door bottoms on the rest of the building are already dark bronze. Both are the same aluminum profile at 13/32 by 11/32 inch, so the finish choice is cosmetic only and either one will match the other openings dimensionally.
8) Will this astragal stop drafts and air infiltration between a pair of commercial doors?
Air infiltration is the tested claim on the Pemko 369: it is tested to ASTM E283-04 (2012) for air infiltration resistance, and the pile brush holds a continuous seal against draft, dust, moisture, fumes, light and sound at the meeting stiles. It also carries GREENGUARD Gold certification for low chemical emissions, which is the certification that comes up on healthcare, clean-room and school projects. Healthcare and clean-room environmental control are among the applications the manufacturer names for it.
9) The Pemko 369 is a split astragal - what overlapping astragal covers the same meeting stile if the pair needs a lapped seal?
Two overlapping types cover that opening. The NGP 109N is an overlapping astragal with a neoprene seal, supplied in 84 inch lengths for commercial doors, and the NGP 176A 84 is an overlapping astragal in anodized aluminum, also 84 inches. The difference from the Pemko 369 is how the seal closes the gap: the 369 is a split astragal, with aluminum sections carrying a pile brush insert at the meeting stiles, while an overlapping astragal carries a lip that laps across onto the adjacent leaf. That distinction matters when the pair has to swing in a set order, because a lapped astragal establishes an active and inactive leaf at the meeting stile. Confirm door swing and leaf sequence before switching between the two styles.
10) Does the pile brush come with the Pemko 369 or is the insert a separate order?
The brush is part of the part. Every orderable configuration of the 369 is the aluminum profile with the pile brush insert already specified, so the only two decisions on the order are finish, mill or dark bronze anodized, and length, 48 inch or 84 inch. Four combinations in total, all of them pile brush.
11) What astragal should be used when the pair needs a bare metal section with no seal insert at all?
The NGP 139A is a solid metal astragal of anodized aluminum construction, with no insert carried in the profile. That is the option when the pair needs the gap covered by metal alone - for example where a brush or elastomer element would be a maintenance item or would not survive the traffic. The Pemko 369 takes the opposite approach: it is an aluminum profile, 13/32 inch wide by 11/32 inch high, built around a pile brush insert that gives it the seal against draft, dust, moisture, fumes, light, and sound. Choose by whether the opening is being sealed for environmental control or simply covered at the meeting stile.
12) Which astragals besides the Pemko 369 come in anodized aluminum for matching existing door trim?
The NGP 139A is a solid metal astragal in anodized aluminum construction, and the NGP 176A 84 is an 84 inch overlapping astragal in anodized aluminum door trim. The Pemko 369 is offered in mill finish aluminum, ordered as 369AP, and dark bronze anodized aluminum, ordered as 369DP. For a building being standardized on one look across a run of pairs, the anodized aluminum options are the ones to compare, but confirm the exact anodize shade against the doors already installed, since anodized coatings from different runs and different makers will not always read as the same color side by side.
