Zero International 429AA 36" x 84" Aluminum Non-Mitered Head and Jamb Gasketing with Silicone

No. The Zero 429AA is a compression-style perimeter gasketing with a silicone insert, and it is BHMA certified with UL 10C fire rating and smoke and draft control. The NGP 602A is a nylon brush seal in an anodized aluminum housing, which sweeps rather than compresses against the stop. The aluminum housings look similar on the shelf and both run the head and jambs, but a brush seal and a silicone compression insert are different sealing mechanisms, and a brush is not the part to order when the opening was specified for smoke and draft control. Order the 429AA where the drawing calls for the silicone perimeter seal.

The Zero 429AA is an aluminum head and jamb perimeter gasketing carrying a silicone insert in an anodized aluminum frame. The nearest like-for-like from another maker is the Cal-Royal PG-601, an aluminum channel perimeter gasketing that seals the same head and jamb positions but carries a vinyl insert rather than silicone. The NGP 155V is also a perimeter seal with a vinyl insert, mounted in a mill aluminum frame rather than an anodized one, so the frame appearance differs from the 429AA's anodized aluminum finish. If the opening was drawn around the 429AA's silicone insert and its UL 10C fire rating and smoke and draft control listing, hold the 429AA; the vinyl-insert channels are the closest substitutes on form and mounting position.

Silicone holds up better to heat and stays flexible over a wide temperature swing, which is why it is the insert used on fire and smoke rated openings like the Zero 429AA. If the opening is not rated and you just want a basic exterior or interior seal, a vinyl insert such as the NGP 155V vinyl perimeter seal or a neoprene sponge like the NGP 108NA, rated for -20 F to 200 F, does the job. Brush seals like the NGP 602A nylon brush are for sweeping dust and light air, not for a sealed rated assembly.

The 429AA comes in AA clear anodized aluminum only. That is the standard mill-look anodized finish, so it lines up with most existing aluminum perimeter seals and aluminum frames already in a commercial building. If you need to match an anodized run on other openings, the NGP 159MA magnetic seal and the NGP 108NA sponge seal are also anodized aluminum housings.

Yes. Zero perimeter seals are used as adjustable sealing systems for sound control, and the 429AA is the head and jamb half of that. For the full acoustic seal you still need to close the gap at the bottom of the door, since a perimeter seal only handles head and jambs.

The Zero 429AA uses a silicone insert in an anodized aluminum frame for head and jamb sealing. Where a buyer wants a published operating temperature band to check against the opening, the NGP 108NA is a neoprene sponge seal in an anodized aluminum frame rated for a temperature range of -20 F to 200 F. Both mount to the head and jambs in an aluminum carrier, so the change is the insert material and its stated temperature envelope, not the mounting approach. Note that the 429AA is BHMA certified with UL 10C fire rating and smoke and draft control, so on a labeled opening confirm the replacement carries the listing your drawing calls for.

The Zero 429AA is an adjustable silicone perimeter seal in an anodized aluminum frame for head and jamb use, and Zero perimeter seals are described as ideal for sound control. Where the specifier wants a magnetic seal instead, the NGP 159MA is a magnetic seal in anodized aluminum sold in an 84 inch length, which matches the 84 inch jamb height the 429AA covers. A magnetic seal pulls the door leaf against the stop rather than relying on a compressed silicone insert, so verify the door is steel or has a magnetic strike surface before substituting.

Case quantity on the 429AA is 2 sets, so a case does two openings. Useful if you are gasketing a run of stair or corridor doors and want to order by the case rather than the piece.

The 429AA is built for commercial openings, and the specs on it are aimed at rated and institutional doors. It will physically mount on any frame with 1-1/2 inches of flat face and a 36 x 84 inch door, but on a house door you are paying for a fire and smoke rated seal you do not need.
