Zero International 8192AA Clear Anodized Aluminum Door Sweep with Nylon Brush

That's exactly the opening it's built for. The 8192AA is a surface-mounted sweep for out-swinging exterior doors, and the nylon brush plus the sweep body deflects rain water away from the bottom of the door. On an in-swinging door the brush sits on the wrong side of the weather line, so an in-swing opening usually wants an interior-side sweep or a door bottom instead.

Six lengths of the 8192AA are made: 36, 40, 41, 42, 44 and 48 inches, all in clear anodized aluminum. For a 36 inch wide door leaf, the 36 inch sweep is the match. Standard practice is to order the sweep at or just over the door width and cut the aluminum carrier down on site, so on an odd width, take the next length up rather than the next one down.

Yes. The 8192AA carries a UL10c fire rating, so it can go on a fire rated opening. It also meets ANSI/BHMA R3A436. Those two lines are what a facility inspector or an AHJ will ask for on a labeled door, and they are the reason this sweep gets specified in schools, hospitals and other institutional work.

The 8192AA has an aluminum carrier 1 inch high with the nylon brush adding 0.625 inch below it. That brush reach is what closes the undercut, so it suits a normal undercut at the sill rather than a large gap. Measure from the bottom of the door to the threshold at the widest point of the sweep; the fastener slots let you set the height so the brush just contacts.

The nylon brush on the 8192AA sweeps over rough or uneven thresholds and slides rather than drags, which is why it holds up on exterior doors that see a lot of traffic and on sills that aren't dead flat. A solid vinyl or neoprene blade seals tighter against air and small debris but scuffs and takes more force to open when the floor is out of level. Pick the brush where the door moves constantly or the sill is irregular; pick a solid seal where a tight air seal matters more than easy operation.

Face mounted. The 8192AA is surface-applied to the door with fasteners, so there's no routing, no mortising, and no door prep beyond drilling. That makes it a straight retrofit on an existing door, including a labeled fire door where cutting into the leaf isn't permitted. Zero publishes install instructions for its door sweeps if the crew wants the fastener layout before they get on site.

Commercial. The 8192AA is a commercial-grade door sealing product, and the clear anodized aluminum carrier is the finish specified on most storefront and hollow metal exterior doors. For a property manager standardizing a building, clear anodized is the neutral that blends with mill-finish aluminum entrances rather than trying to match a painted door.

AA is Zero's finish code for clear anodized aluminum. It identifies the finish on the sweep's extruded carrier, not the length or the seal type. So when you're matching sweeps across a set of doors and someone hands you a part number ending in AA, they're on clear anodized. The 8192 number is the sweep itself, brush seal on an aluminum body.
