Zero International 41AA 84 – Frequently Asked Questions

1) What does the Zero International 41AA meeting stile do on a pair of doors?
The 41AA is an astragal that mounts on the meeting edge of a pair of doors, where the two leaves come together. The extruded aluminum carrier holds an elastomeric seal that compresses when the doors close, blocking air, sound, light, smoke and dust through the gap between leaves. It handles the vertical joint only, so door bottoms and the frame perimeter still need their own sweep and gasketing.
2) Does the 41AA meeting stile mortise into the door edge or surface mount?
Surface mount. The extrusion screws onto the face of the door along the meeting edge, so there is no routing or mortising of the stile. Pre-drilled holes and mounting screws come with it. That makes it workable on an existing pair in the field, not just on new doors, but check that the applied thickness clears any astragal, lock trim or exit device hardware already on that edge.
3) Do I need one 41AA astragal or two for a pair of doors?
One. A meeting stile astragal mounts to a single leaf, usually the inactive one, and seals against the face of the opposite leaf when the pair closes. You order one 84 inch piece per opening, not one per door.
4) Is the 41AA seal neoprene or silicone, and does that matter?
The 41AA carries an elastomeric seal insert, specified as silicone or neoprene. It matters on exterior and high heat openings: silicone stays flexible across a wider temperature swing and resists UV and ozone better, which is what you want on a west-facing entry pair. Neoprene is the workhorse on interior and sheltered openings. Both compress the same way against the opposite leaf.
5) Will an astragal like the 41AA seal the bottom of my doors too?
No. An astragal only closes the vertical gap where the two leaves meet. The bottom of each leaf needs a door sweep or a door shoe over the threshold, and the head and jambs need perimeter gasketing. On a pair, budget for the astragal plus two bottom seals plus the frame gasketing to get a complete seal.
6) Does anything come in the box with the 41AA, or do I need to buy fasteners?
Mounting screws and installation instructions ship with it, and the extrusion is pre-drilled, so a standard install needs no additional fasteners. If you are anchoring into an aluminum storefront stile or a glass door rail rather than hollow metal or wood, plan on fasteners suited to that substrate.
7) What finish does the Zero 41AA come in?
Clear anodized aluminum is the stocked finish, an 84 inch clear anodized piece. Clear anodized reads as a light satin silver and blends with aluminum storefront and most anodized door frames without looking like an add-on part.
8) Is the Zero 41AA meant for commercial openings or houses?
It is a commercial-rated part. Zero builds it for commercial and institutional pairs, the kind of traffic you get on a school, medical office or apartment common entry, though nothing stops it going on a residential double door. The aluminum extrusion and screw-applied mounting are the same as on any storefront or hollow metal pair.
