Zero #339W Door Bottom, Aluminum or Bronze Casing with 1.5" Neoprene Seal

This door bottom is an ideal solution for sill protection. It can fill up to 1.5" of space beneath a door. The strong aluminum casing on this door sweep is fitted with a durable solid neoprene seal, which is an effective barrier for smoke, and can withstand constant usage. It can also be applied to a single active double door as a meeting stile (See our 1.5" Smoke Rated Meeting Stile).

Installation instructions and screws included. Screws are colored to blend unobtrusively with casing.

A Note on Finishes: Aluminum Mill Finish is plain smooth metal as it comes from the mill, without a coating. Bronze is a mill finish, sometimes referred to as Architectural Bronze. It is a solid bronze piece, which increases longevity and aesthetics, thus the large difference in price. It gets darker in color in time when exposed to the environment. Anodizing is an electrolytic process that applies a corrosion-resistant coating to the aluminum for longer wear and color maintenance. All Zero's anodized products are anodized to 204 (dipped four times)!
