Zero International 429AA-36X84 – Frequently Asked Questions

1) Is the Zero 429 head and jamb gasketing fire rated?
The Zero 429 gasketing set is fire rated to UL10C and also carries ANSI/BHMA R3E164. It is rated for smoke and draft control as well, which is what matters on a rated opening where the inspector is looking for a listed perimeter seal rather than a generic weatherstrip.
2) What sizes does the Zero 429 gasketing set come in, and will one set do a whole door?
The 429AA is sold as a set in 36 x 84 inch and 72 x 84 inch. The 36 x 84 covers a single door: one 84 inch jamb leg plus head material. The 72 x 84 set is the one to order for a pair of doors, giving two 84 inch jamb legs. The stock is full length and field cut to size, so you trim on site to the exact opening.
3) Will the Zero 429 gasketing work on a door that has a closer bracket or a door coordinator on the frame?
That's exactly what the 429 is built around. The profile is intended for use with a door closer bracket or a door coordinator, so it seals the head and jamb without the closer shoe or coordinator body fighting the gasket. On a pair of doors with a coordinator across the head, this is the head and jamb set to specify.
4) Does the Zero 429 seal the bottom of the door too, or do I need a separate door bottom and threshold?
Head and jamb only. The 429 set seals the perimeter at the top and both sides of the opening. The bottom gap is a separate item: you'll need a door bottom or automatic door bottom, and a threshold or sweep, ordered on their own. Buyers sealing a full opening typically pair a Zero head and jamb set with a Zero automatic door bottom.
5) What is the sealing element on the Zero 429, and does it hold up in cold or heat?
Silicone. The 429AA carries a silicone seal in a clear anodized aluminum retainer. Silicone is the element to ask for on exterior and mechanical room doors because it stays flexible through temperature swings rather than taking a set the way some compression materials do, and it is what makes the set usable on a smoke and draft rated opening.
6) Can I cut the Zero 429 gasketing down to fit a shorter frame?
Yes, the 429 ships full length and is field cut to size. Measure the frame rabbet, cut the head piece and the two jamb legs, and fasten. Ordering the 84 inch stock and trimming is normal practice; ordering short and splicing is not, so size up rather than down when the opening falls between the 84 inch lengths.
7) Do I need to mortise the frame to install Zero 429 head and jamb gasketing?
No mortising. Head and jamb gasketing of this type is surface applied to the frame stop, which is why it is the go-to retrofit for an existing opening that needs to be brought up to a smoke and draft seal. Nothing about the door leaf changes, so it can go on doors already hung and in service.
8) Is the Zero 429 gasketing meant for commercial openings or will it work in a house?
Commercial. The 429 is a commercial door hardware item, built for the traffic and the code requirements of institutional, healthcare, education, and multi-family corridor openings. It will physically install on a residential door, but you are buying a UL10C rated smoke and draft seal, which is specified for rated commercial openings.
9) What does the AA in Zero 429AA mean and will it match my other aluminum frames?
AA is the clear anodized aluminum finish. It reads as a natural silver aluminum, which is what matches most storefront and hollow metal aluminum frames and the mill or anodized closers and door bottoms already on those openings. If your building is standardized on dark bronze or a painted frame, the clear anodized will contrast.
