Pemko 303DV3696 – Frequently Asked Questions

1) How big a gap will the Pemko 303 perimeter gasket close on a commercial door?
The 303 is a small profile stop-applied gasket measuring 1/4 inch wide by 1/4 inch high, and it seals gaps up to the depth of its seal. That makes it a fit for doors hanging reasonably true against the stop. If your door is racked and you are chasing a gap wider than a quarter inch at the jamb, this profile will not bridge it and you want a deeper adjustable jamb seal instead, such as the Hager 864S adjustable jamb weatherstrip with a neoprene insert.
2) What is the difference between the Pemko 303 perimeter gasket and the Hager 864S adjustable jamb weatherstrip?
Both are aluminum jamb-applied perimeter weatherstrips, but the seal and the finish differ. The Pemko 303 is an aluminum weatherstrip in dark bronze anodized aluminum, 1/4 inch wide by 1/4 inch high, supplied in 96 inch lengths and punched on 6 inch centers with slotted holes so the carrier can be shifted for gap adjustment. The Hager 864S is an 84 inch clear anodized aluminum adjustable jamb weatherstrip with a neoprene insert. If you are matching dark bronze frames and need a full 96 inch jamb leg, the 303 covers it; if the frames are clear anodized and 84 inches is enough for the run, the 864S is the direct counterpart.
3) For a smoke and draft control opening, is the Pemko 303 gasket the right weatherstrip or should a different product be used?
Match the product to the sealing job. The Pemko 303 is a standard perimeter gasket, 1/4 inch by 1/4 inch aluminum, that seals gaps up to the depth of its seal and works as either a perimeter or meeting stile gasket. When the opening is specifically a smoke and draft assembly, the Hager 862S is a 48 inch weatherstrip with a neoprene insert built for smoke and draft control, and the Hager 726S is a press-on smoke seal weatherstrip in a charcoal finish for openings where a surface-applied seal is wanted rather than a screw-applied aluminum carrier.
4) Can the Pemko 303 gasket be adjusted after it is mounted, or is the position fixed?
Adjustable. The aluminum retainer is punched on 6 inch centers with slotted holes, so you can set the screws, close the door, and shift the strip in or out against the seal before final tightening. That matters on a door that does not sit perfectly square in the frame, since you can tune the compression jamb by jamb instead of relying on the door fitting the stop exactly.
5) Does the Pemko 303 come in a version I can install without drilling and screwing?
The 303 is offered with self-adhesive two sided tape (TST) as well as with TEK screws. Tape is the faster route on a retrofit where you do not want to put new holes in a finished frame, though on a high traffic opening the screw-applied version holds up better because the fasteners carry the load rather than the adhesive. If you want a press-on seal with no fasteners at all, the Hager 726S is a press-on weatherstrip.
6) Can the Pemko 303 be used on the meeting stile of a pair of doors, or only on the jamb?
Both. The 303 works as a meeting stile gasket as well as a perimeter gasket, so on a pair of doors you can run it up the head and hinge jambs and use the same profile where the two leaves meet. Ordering one part for the whole opening keeps the finish consistent across the jamb and the meeting stile.
7) How much Pemko 303 weatherstrip do I need to order to do one commercial door?
A single opening takes the head plus both jambs. One 96 inch stick of the 303 covers a standard head run with material left over, but it will not do the head and two 84 inch jamb legs from one piece, so budget two sticks per single door and cut to suit. For a pair, add the meeting stile run, which this same profile handles.
8) Is a brush weatherstrip or a compression gasket like the Pemko 303 the right choice for my doors?
A compression gasket like the 303 seals by squeezing against the stop when the door closes, which is what you want on a swinging perimeter seal for weather and draft control. A brush seal, such as the Cal-Royal BW-302 nylon brush weatherstrip in an extruded aluminum retainer, wipes rather than compresses, so it suits sliding leaves and openings where the door drags past the seal instead of closing into it. Pick compression for a hinged commercial door, brush where there is constant sliding contact.
9) What is the difference between the Pemko 303 and the PemKonnect modular 303AS3684-M?
Same 303 family, different packaging and seal. The PemKonnect modular version, 303AS3684-M, carries a silicone insert and folds down for compact shipping, which cuts freight and storage on volume orders. It is also UL listed and BHMA certified, so it is the one to spec when the opening has to satisfy a code or listing requirement. The standard 96 inch dark bronze 303 is the straight stick version.
10) Which weatherstrip should be used on a door with an uneven gap or a rough frame instead of the Pemko 303?
The Pemko 303 uses a fixed 1/4 inch by 1/4 inch aluminum profile and seals gaps up to the depth of its seal, so it suits an opening with a consistent, in-tolerance gap. Where the gap varies along the leg or the frame face is irregular, the Cal-Royal BW-302 is a nylon brush weatherstrip in an extruded aluminum seal retainer; brush filaments bridge an inconsistent gap and tolerate surfaces a solid seal would ride off of. Both mount as an aluminum carrier on the jamb, so the install method is familiar either way.
11) Can the Hager 726S press-on smoke seal be substituted for the Pemko 303 weatherstrip gasket?
They install differently and should not be treated as drop-in equivalents. The Pemko 303 is an aluminum-carrier gasket punched on 6 inch centers with slotted holes, so it is fastened to the frame and can be adjusted to the gap after the holes are set. The Hager 726S is a press-on smoke seal weatherstrip in a charcoal finish, applied to the frame surface without a fastened aluminum retainer. On a frame already drilled for a screw-applied carrier, or where dark bronze anodized aluminum needs to match adjacent hardware, the 303 is the one to specify.
12) For a standard 7 foot commercial door jamb, which weatherstrip covers the full leg without splicing?
The Pemko 303 comes in a 96 inch length, which runs an 84 inch jamb leg in one piece with material to cut back, and the 303 profile is offered from 24 inches minimum up to 185 inches maximum for taller or wider openings including the head. The Hager 864S adjustable jamb weatherstrip is furnished at 84 inches and the Hager 862S at 48 inches, so those suit a jamb leg cut to size and shorter runs respectively. Choose on the run length you need to cover in a single piece.
13) What finish does the Pemko 303 96 inch weatherstrip come in, and will it match dark bronze door hardware?
Dark bronze anodized aluminum is the finish on the 96 inch 303. Anodized bronze on aluminum reads as a dark brown, which lines up with dark bronze frames and bronze finish hardware on the same openings. If you are standardizing a building of aluminum entrances already finished in dark bronze, this keeps the perimeter seal from standing out against the frame.
14) Will aluminum weatherstrip like the Pemko 303 hold up in a high traffic building or a corrosive environment?
The retainer is aluminum, which resists corrosion and takes the abuse of commercial traffic better than a plastic carrier. That is why it turns up on office buildings, schools, healthcare, retail, warehouses, multi-tenant residential, and government facilities. The dark bronze finish is anodized, so it is part of the metal rather than a coating that scuffs off at the strike jamb.
