S4S - 1/2X3X16 PRF S4S Boards

S4S Trim Boards

Bring clean, straight-lined detail to custom trim work with S4S boards. S4S means surfaced on four sides, giving you a board format for planning flat trim and custom finishing pieces.

Use flat boards to build out door and window surrounds, trim assemblies, or other nonstructural finishing details. For a modern look, keep the proportions balanced and repeat the same edge treatment throughout the space.

Coordinate the board finish with adjoining casing, baseboard, and wall details for a consistent result.
