Moulding Collection

S4S is the abbreviation for lumber that has been surfaced on four sides. When a board is surfaced, it has been milled through a joiner or a planer, making rough lumber smooth and square. S4S is great for projects where all four sides of the wood will be seen, like in fences, decorative railings, furniture, and carved wood projects.
