Hager 726S-17FT – Frequently Asked Questions

1) Is the Hager 726S smoke seal UL listed for fire doors?
The 726S carries a UL Listed Warnock Hersey listing, which is what lets it be used as gasketing on fire-rated door assemblies. It is a smoke seal system, so it is doing two jobs at once: smoke control at the perimeter and air infiltration sealing. Note the listing applies to the seal as supplied; a fire door assembly still has to be gasketed per the door manufacturer's listing.
2) Does the Hager 726S weatherstrip need a kerf in the frame?
No. The 726S is a press-on seal with adhesive backing, so it goes on the face of the stop or the door edge with no kerf and no screws. If your frames already have a kerf cut in the stop, a kerf-in seal such as the Pemko Q103W foam weatherstrip drops straight into that groove instead and gives a cleaner look with nothing exposed to peel.
3) What is the difference between the Hager 726S smoke seal and the Pemko Q103W kerf-in weatherstrip?
The two mount in completely different ways. The Hager 726S is a press-on silicone smoke seal that adheres to a cleaned frame or door face, so it goes onto a frame that has no groove machined into it. The Pemko Q103W is a kerf-in foam weatherstrip with an extended flange, measuring 1-1/4 inch by 3/16 inch, and it needs a kerf slot in the frame stop to hold its barb. Check the frame before ordering: a kerf frame takes the Q103W, and a flat frame face takes the press-on 726S. Both carry a fire rating, and the 726S is UL Listed Warnock Hersey.
4) Can a nylon brush weatherstrip be used in place of a silicone smoke seal on a fire door?
No, treat those as two different products. The Cal-Royal BW-302 is a nylon brush weatherstrip carried in an extruded aluminum seal retainer, and a brush pile is built for sweeping dust and blocking drafts, not for forming the continuous compression seal a smoke assembly needs. The Hager 726S is a silicone smoke seal, flame resistant, UL Listed Warnock Hersey, and part of Hager's Smoke Seal Systems features. For a fire-rated opening where the inspector is looking for smoke gasketing, the 726S is the one that answers to that; the BW-302 is the choice when the job is dust, light, and air movement on a non-rated door.
5) I only need to gasket the head of one fire door. Is there a better option than a 520 foot coil?
For a single opening, the Pemko 68 is a fire-rated door top weatherstrip supplied at 40 inches with a black sponge neoprene insert, which is a cut length sized to one door head rather than a coil. The Hager 726S is sold by the coil in lengths from 17 feet to 520 feet, which suits a project where the head and both jambs of many openings are being gasketed in one pass and the installer cuts to length on site. Choose the 68 for a one-door head repair and the 726S coil when the count of openings makes continuous stock the practical buy.
6) Will silicone weatherstrip hold up better than brush or foam on an exterior commercial door?
Silicone is the pick where the seal sees heat, sun, or wet. The 726S uses a silicone bulb that is flame resistant and moisture resistant, which is why it can carry a fire listing at all. A nylon brush seal like the Cal-Royal BW-302 sweeps dust and tolerates a rougher, less consistent gap but does not seal air the way a compressed bulb does. Foam kerf-in seals such as the Pemko Q103W seal well and sit hidden, but foam is the material that goes hard and crumbles first in UV.
7) Can I use the 726S press-on seal on the door itself instead of the frame?
Yes, the adhesive works on either surface. On a hollow metal frame the usual run is on the face of the stop so the door closes into it. On a pair of doors with no mullion, or where the stop is too narrow to take the 1/2 inch base, put it on the door edge instead. Either way the surface has to be clean and free of oil or dust before the backing comes off, and the seal has to make continuous contact once the door is shut, or the smoke seal is only as good as its worst gap.
8) Can I standardize one smoke seal across a whole facility's fire doors?
That is the case for buying the 726S in long coils. One profile at 1/4 by 1/2 inch, one material, two colors, and coil lengths up to 25 feet means a maintenance shop can stock a single item and gasket any opening in the building rather than matching a different seal to each frame. The limit on standardizing is the frame: openings with a kerfed stop want a kerf-in seal, and openings with a wide, inconsistent gap are better served by a brush seal like the Cal-Royal BW-302.
9) I need a fire-rated seal for just the top of one door, not a whole coil. What are my options?
The 726S starts at a 17 foot coil, which is a full opening's worth of material. For a single door top, the Pemko 68 is a fire-rated door top weatherstrip supplied as a 40 inch piece with a black sponge neoprene insert, sized to one head without the offcut. Go back to the 726S coil when you are gasketing jambs and head together or doing more than one opening.
10) Is a neoprene insert weatherstrip the same thing as a silicone smoke seal?
They are different elastomers and the material is worth confirming on the submittal. The Pemko 68 uses a black sponge neoprene insert in a fire-rated door top weatherstrip. The Hager 726S is silicone, flame resistant and moisture resistant, at a 1/4 inch by 1/2 inch profile. Silicone holds up to heat and moisture cycling differently than sponge neoprene, so where a specification calls out silicone gasketing by name, the 726S meets that wording and a neoprene insert product does not.
11) What colors does the Hager 726S smoke seal come in?
Charcoal and brown. Charcoal disappears against dark bronze and black frames and against most gray hollow metal; brown is the one to order against wood doors and duranodic or brown-painted frames. Both colors are stocked in every coil length, 17 through 25 feet.
12) Is the Hager 726S meant for commercial doors or will it work on a house?
The 726S is built and rated for commercial work, and that is where it earns its keep: fire-rated openings in offices, schools, hospitals, government buildings, and multi-tenant residential corridors. Nothing stops it going on a residential door, but you are paying for a silicone smoke seal with a fire listing to do a job a plain foam or brush seal would do.
13) Will the 726S help with air leaks and drafts, or is it only for smoke?
Both. The 726S is air infiltration and energy performance tested in addition to being a smoke seal system, so the same silicone bulb that blocks smoke at the perimeter also cuts the draft and the conditioned air you lose around an exterior or stairwell door. Perimeter gasketing is usually the cheapest air-sealing you can do on an existing opening.
14) What can I use if the door bottom and sides need a sweep-type seal instead of a compression gasket?
Look at the Cal-Royal BW-302, a nylon brush weatherstrip mounted in an extruded aluminum seal retainer. The brush pile bridges an uneven gap and rides over surface irregularities, which is why it is used where a compression gasket would bind the door. The Hager 726S is a press-on silicone gasket that seals by compression against the stop, so it wants a consistent, straight contact surface. On a door that is out of plumb or has a wide, varying gap, the brush retainer is the more forgiving of the two.
