Zero International 383FS-AA 83 – Frequently Asked Questions

1) What is an astragal like the Zero 383FS actually for on a pair of doors?
It seals the vertical gap where two doors meet. The 383FS is a surface-mounted meeting stile seal for paired openings, so it mounts on the face of one leaf and closes the crack against the other. That gap is the one a door sweep and head/jamb gasketing never touch, and on a fire-rated pair it is where smoke moves first. Use it where you have a pair with no center mullion and need the meeting edge sealed for smoke and for sound.
2) Is the Zero 383FS astragal fire rated, and is it smoke rated too?
Both. The 383FS is fire rated to UL10c and is smoke seal rated. That combination is what a healthcare or education facility needs at a rated pair: the UL10c rating covers it for use in fire-rated door assemblies, and the smoke seal rating covers smoke migration through the door perimeter.
3) Will the Zero 383FS fit my doors, or do I need to cut it?
It comes in one length, 83 inches, for 83 inch door openings. Standard commercial door leaves are 84 inches, so an 83 inch seal is the normal stock length for a full-height opening. If your doors are taller than that, this piece will not cover the full meeting edge and you want a longer meeting stile instead.
4) Can the Zero 383FS be added to doors that are already hung?
Yes. It is a surface mount astragal, so it screws to the face of the existing door leaf. No mortising, no routing, and no removing the door from the frame. That is the practical difference between this and a mortised or overlapping-edge astragal, which needs door prep and usually a shop.
5) What makes the 383FS work in a fire assembly and not just a plain weatherstrip?
Two things in the seal itself. There is an Intumet insert that expands under heat to block smoke and flame at the opening, and the solid neoprene insert is self-extinguishing rather than ordinary rubber. A standard neoprene or vinyl meeting stile has neither, which is why it cannot go on a rated pair.
6) Will the Zero 383FS help with noise between rooms?
That is one of its jobs. The solid neoprene insert and the adjustable seal are meant for sound control, closing the meeting-stile gap that leaks the most noise on a pair of doors. Worth knowing that a meeting stile alone does not make an acoustic opening, you still need the head, jambs and bottom sealed to get a real reduction.
7) What finish does the Zero 383FS meeting stile come in?
Clear anodized aluminum, one finish. It reads as a plain silver strip down the meeting edge, which sits fine against aluminum storefront and most painted hollow metal. If you need it to disappear against a dark or bronze door, this is not the piece.
8) Is the Zero 383FS suitable for a commercial building or is it a residential product?
Commercial. It is specified for commercial door openings, and the applications it is built for are offices, schools, hospitals, retail, warehouse, multi-tenant residential and government buildings. In a multi-family building it belongs on the rated corridor and stair pairs, not on unit entry doors, which are single leaves and take perimeter gasketing instead.
