Kebony North America

The historical 8110-2351:0001 construction names Clear Radiata Boardwalk, Deck Board and Square Deck Board, with nominal 5/4-by-6-inch and 2-by-6-inch dimensions. It requires nominal 2-by-6-inch Douglas fir joists at 16-inch centers, an edge gap no greater than 3/16 inch, and mechanical attachment using FastenMaster TrapEase 3 deck screws 2-1/2 inches long.

OSFM's September 2025 handbook gives Class B flame spread and SFM 12-7A-4A. The listing was absent from the August 25, 2026 BML check; that observation does not identify expiration, withdrawal or renumbering as its cause.

Start with confirmation of the exact product's current GOVmotus listing. If reviewing the historical construction, retain its named screws and joist arrangement along with the board sizes, and consult Kebony's installation instructions and product data sheets. A historical Class B label does not resolve current listing coverage.
