Pemko 347A-52 – Frequently Asked Questions

1) Will the Pemko 347A door top weatherstrip work on an inswing door?
No. The 347A is an overhead interlocking weatherstrip built for outswing doors, where the door face closes against the seal and the rain drip can shed water off the exterior side. On an inswing opening the door swings away from the head seal, so an interlocking top strip has nothing to interlock with. For an inswing door you want a jamb-applied head seal instead, such as the Hager 864S adjustable jamb weatherstrip.
2) What length Pemko 347A do I order for a 36 inch door?
Order the strip at least 4 inches longer than the door width, so a 36 inch door takes a 40 inch piece. That extra length lets the strip run past the opening on both sides at the head. Stock lengths run 36, 40, 52, 84 and 88 inches, and custom cuts are available from 24 inches up to 185 inches maximum.
3) Is the Pemko 347A fire rated for a labeled door opening?
Yes. The 347A is UL 10C positive pressure fire tested and UL 1784 smoke tested, and it is BHMA Certified. That combination is what a labeled opening in a hospital, school or government building typically calls for on the head seal. It also carries GREENGUARD Gold certification if your project has indoor air quality requirements.
4) How much clearance does the Pemko 347A need above the door at the head?
The strip measures 1 1/8 inches in overall height and 3/4 inch in width, so you need that much room on the head stop to mount it without fouling the door swing. On a retrofit, check the existing head condition against those two numbers before you order, since an interlocking top strip has to sit where the door face passes it.
5) What is the difference between the Pemko 347A and the Hager 864S weatherstrip?
They seal different parts of the same opening. The Pemko 347A is a door top interlocking weatherstrip with a rain drip design, 1 1/8 inch overall height by 3/4 inch width, in an aluminum casing with a silicone interior, and it runs the head of an outswing door to shed water away from the face. The Hager 864S is an adjustable jamb weatherstrip in clear anodized aluminum with a neoprene insert, 84 inches long, so it addresses the strike and hinge jambs and its adjustability lets an installer take up an uneven gap after the door is hung. On a full perimeter seal package a crew often runs one across the head and the other down the jambs rather than choosing between them.
6) I need a head seal on an interior smoke door, no exterior exposure. Is there something simpler than the Pemko 347A?
Yes. The Pemko 347A is built for weather exposure - the rain drip profile exists to throw water off an outswing exterior door, and the aluminum casing has to be fastened as an interlocking piece at the head. On a dry interior opening the Hager 726S is a smoke seal weatherstrip with press-on installation in a charcoal finish, which goes on without the aluminum retainer work. Where the interior opening is fire and smoke rated and you want the same tested assembly the exterior doors use, the 347A is UL 10C positive pressure fire rated and UL 1784 smoke tested, and it is also GREENGUARD Gold certified.
7) My doors are all different widths. Which weatherstrip do I order, the Pemko 347A or the Hager 862S?
The Pemko 347A is cut to order in custom lengths from 24 inches minimum to 185 inches maximum, and the ordering rule is a minimum of 4 inches longer than the door width, so a mixed set of openings can each get an exact piece. The Hager 862S is a 48 inch weatherstrip with a neoprene insert for smoke and draft control, which is a fixed cut length. For a facility standardizing across doors of one width, a fixed length keeps ordering simple; for a building with odd widths, transoms, or pairs, the 24 to 185 inch custom range of the 347A avoids field splicing at the head.
8) What is the Pemko 347A actually made of, and will the seal hold up outdoors?
Aluminum casing with a silicone interior seal. Silicone is the reason it works on an exterior head: it stays flexible through temperature swings rather than taking a set the way a foam or a vinyl bulb can. The aluminum housing is what the rain drip is formed into, deflecting water off the door face.
9) Do I need anything else to complete the weatherseal with the Pemko 347A?
The 347A handles the top of the opening only. It works with the Pemko 68 Series aluminum silicone housing so the head, jambs and any astragal read as one system. You will still need jamb seals and a threshold or door bottom to close the rest of the perimeter.
10) Should I use an interlocking door top weatherstrip or a brush or press-on seal?
An interlocking strip like the Pemko 347A gives a positive mechanical seal at the head and sheds water, which is what an exterior outswing door needs. Brush and press-on seals are for lighter duty and interior work: the Cal-Royal BW-302 uses a nylon brush in an extruded aluminum retainer, and the Hager 726S is a press-on smoke seal. Those go on faster and take no head clearance, but they do not shed water off the door face.
11) I just need smoke and draft control on an interior door, not weather. Is the 347A overkill?
For an interior opening with no water exposure, yes. The rain drip on the 347A does nothing indoors and the interlocking profile takes more head clearance and more install time. The Hager 862S with a neoprene insert is built for smoke and draft control, and the Hager 726S press-on smoke seal is the simplest option. Where the interior opening is fire labeled, note the 347A is the one here carrying the UL 10C and UL 1784 test data.
12) Can I use the Pemko 347A on a pair of doors or a wide opening?
Yes, up to 185 inches in a single piece, which covers most pairs and oversized openings without a splice at the head. Order the strip 4 inches longer than the total opening width. Below 24 inches it is not made, so very small openings need a different seal.
13) Can I use a brush weatherstrip instead of the Pemko 347A?
A brush seal is a different sealing method and suits a different gap. The Cal-Royal BW-302 is a nylon brush weatherstrip with an extruded aluminum seal retainer, so the brush filament sweeps a gap that changes as the door moves - the common use is dust, light air movement, and openings where the door does not close tight against a fixed stop. The Pemko 347A closes the head gap with a silicone interior in an aluminum casing that interlocks with the door top, and its rain drip profile is what sheds water off an outswing exterior door. If the reason for the seal is driving rain at the head, the interlocking silicone design is doing work a brush filament is not shaped to do.
14) What finish does the Pemko 347A come in?
Mill finish aluminum, across every length offered. If you are matching a clear anodized head or jamb condition on an existing storefront, mill finish is the raw aluminum look and will read slightly different against anodized trim.
15) Is the Pemko 347A rated for commercial traffic or is it a residential product?
Commercial. The 347A is specified into office buildings, schools, healthcare facilities, retail, warehouses, multi-tenant residential and government buildings, and it carries the BHMA certification and UL test data those projects usually require on a head seal.
