Zero International 111FS Aluminum Door Shoe with Solid Neoprene Seal, 48"

The Zero International 111FS Aluminum Door Shoe is a 48" u-shaped door bottom that wraps around the base of the door for a superior seal and improved aesthetics compared to standard sweeps. Constructed with an anodized aluminum (AA) housing and supplied with a solid neoprene seal, this door shoe prevents dust, moisture, and drafts from entering at the threshold. It is fire-rated UL10C and carries an ANSI/BHMA R3B414 rating, making it well-suited for commercial applications where code compliance is required.

Zero International 111FS-AA-36 – Frequently Asked Questions

1) What is the difference between a door shoe like the Zero 111FS and a regular surface-mounted door sweep?
A door shoe is U-shaped and wraps around the bottom edge of the door rather than screwing flat onto one face. The Zero 111FS uses that U-shaped housing to grip the door bottom, which seals better than a single-face sweep and leaves a cleaner look because the extrusion caps the door edge instead of hanging off the face. If the door bottom is chewed up or out of square, a shoe also hides it. Surface sweeps are the simpler retrofit; a shoe is the better choice where you want the finished appearance and a tighter barrier against dust, drafts, and moisture.
2) Can I use the Zero 111FS door shoe on a fire-rated door assembly?
Yes. The 111FS carries a UL10C fire rating and an ANSI/BHMA R3B414 certification, so it is intended for code-compliant commercial door assemblies where the door bottom seal has to be a rated component.
3) What lengths does the Zero 111FS aluminum door shoe come in?
Two lengths: 36 inches and 48 inches. The 36 inch covers a standard 3-0 commercial leaf, and the 48 inch gives you extra material to cut down for a 3-6 or 4-0 opening. Order the length at or above your door width and trim the extrusion to fit.
4) Is a neoprene seal the right choice for an exterior door bottom?
The 111FS ships with a solid neoprene insert, which handles dust, moisture, and drafts at the threshold and holds up to weather and ozone better than a plain foam insert. Paired with the anodized aluminum housing, which resists corrosion, it is a reasonable exterior door bottom for commercial entries, warehouse doors, and municipal buildings.
5) Will a door shoe like the Zero 111 work on a wood door, or only metal?
The 111FS shoe fastens to the bottom of the door with the U-channel wrapping the door edge, so it mounts on either a hollow metal or a wood leaf as long as the door bottom is flat and square. What matters more is the undercut: the shoe adds material below the door, so you need enough clearance above the threshold for the neoprene to sweep without binding. On a door hung tight to the floor, the leaf gets trimmed before the shoe goes on.
6) What finish does the Zero 111FS housing come in?
The housing is anodized aluminum, designated AA. That is the clear mill-look anodized finish, so it blends with aluminum storefront and standard commercial frames rather than matching a painted or brass-finish door.
7) Is the Zero 111FS suitable for a high-traffic building like a school or hospital?
It is a commercial-rated product, and Zero lists it for office buildings, schools, healthcare facilities, retail, industrial and warehouse space, and government buildings. For a property manager standardizing across a facility, the anodized aluminum housing and replaceable neoprene insert mean you can restock one part number across openings and swap the seal when it wears rather than pulling the whole shoe.
