Zero International 570AA Self - Adjusting Perimeter Seal with Solid Neoprene

Yes. The 570AA carries a UL10c fire rating and is also rated for smoke and draft control, so it can be used on labeled fire door assemblies where a smoke seal is called for.

That is the point of the Compress-O-Matic design. The 570AA is a self-adjusting perimeter seal: the solid neoprene insert compensates as the door closes rather than relying on one fixed setting, so an opening with an uneven gap still seals. It's a common choice for sound control openings where a consistent seal around the full perimeter matters.

The 570AA is a perimeter seal, meaning it handles the head and the two jambs. The gap at the floor is a separate item, so for a complete seal on a smoke or sound rated opening you'll want to add a door bottom or automatic door bottom, and a threshold or saddle if the floor condition needs one.

Screw mounted. The 570AA fastens mechanically to the frame, not with tape, which is what lets it hold position on a fire rated or high traffic opening. Plan on drilling and fastening the aluminum retainer along the head and both jambs.

Solid neoprene like the 570AA compresses to a firm, continuous contact, which is what you want for sound attenuation and for smoke and draft control on a labeled door. Brush or pile seals are better suited to sliding contact and dust control, not acoustic or smoke work, and they won't give you the compression set this design relies on. If your job spec calls out a smoke and draft rated gasket at the head and jambs, the 570AA meets that.

The retainer is clear anodized aluminum with a solid neoprene sealing element, and it's rated by the manufacturer as a commercial product. Clear anodized is the standard mill-look finish that blends with aluminum frames and storefront.
