Zero International 55AA 96 – Frequently Asked Questions

1) What is a Zero 55AA astragal used for on a pair of doors?
The 55AA is a surface-mounted meeting stile astragal for double doors where both leaves need to stay active. A neoprene insert runs the length of the extrusion and compresses against the opposite door to close the gap where the two leaves meet. Because it mounts on the surface of one leaf and seals against the other, neither door has to be fixed or turned into an inactive leaf, which is the trade-off you make with a fixed mullion.
2) How do you take up the gap when a pair of doors settles and stops sealing?
That is what the adjusting screw is for. The 55AA carries a stainless steel spring and an adjusting screw so the neoprene can be re-set in the field to keep contact as the doors sag, warp, or the closers change the hang. Most surface astragals are a fixed extrusion, so once the gap opens you replace or shim them. This one you adjust in place.
3) What length and finish does the Zero 55AA astragal come in?
One configuration: 96 inch length in clear anodized aluminum. Ninety-six inches covers a standard 84 inch commercial door leaf with material to cut off, so on a typical opening you trim to height on site rather than ordering to size. For a door taller than 96 inches you need more than one piece per leaf.
4) Should I use an adjustable astragal or a removable mullion on a pair of doors?
Depends on whether you need both leaves free. A removable mullion sits in the middle of the opening and has to be pulled to move anything wide through, and it takes the pair out of service as a clear opening. The 55AA seals the meeting stile from the face of one leaf, so both doors stay active and the full opening width stays usable. If your requirement is a rated seal at the meeting stile rather than a strike point for rim exit devices, the astragal is the simpler part.
5) Does a surface astragal go on both doors of a pair or just one?
One leaf. A surface astragal like the 55AA mounts to the face of a single door and its neoprene bears against the meeting stile of the other leaf, which is why it is a single 96 inch piece per pair rather than two. Order one per pair of doors, not one per leaf.
6) Will an astragal on the meeting stile interfere with panic hardware or a coordinator?
A surface astragal projects off the face of the leaf it is mounted to and overlaps the other door, so the pair must close in sequence: the leaf without the astragal has to shut first. On a rated pair with closers that means a coordinator is part of the job. Plan the mounting side so the astragal projection clears exit device end caps and pull trim on the adjacent leaf.
7) Will a clear anodized aluminum astragal hold up in an exterior entrance?
Clear anodized aluminum with a stainless steel spring and adjusting screw is a commercial-duty combination, and the 55AA is a commercial product. Neoprene is the sealing element, and it is the part that takes the compression cycle. Note this is a surface astragal, so it is exposed on the face of the leaf where a cart or a dolly can catch it.
