Solid red oak board surfaced four sides (S4S), meaning all four faces and edges are planed smooth and to consistent thickness and width, ready for layout without further milling. Nominal thickness is called out in the trade as 4/4 stock; actual dressed thickness after surfacing is slightly less than the nominal call-out.

Red oak is an open-grain North American hardwood with pronounced ring figure, good machining characteristics and the density to hold screws, nails and mortises. It accepts stain, dye and clear finish readily, though the open pores usually call for a grain filler where a fully level film finish is wanted.

Wide-width boards like this are used where a finished hardwood face is required rather than a paint-grade substrate: stair components, cabinet and casework parts, shelving, tread and cap stock, and glue-ups for panels and tabletops. Let the material acclimate to interior conditions before final milling and fastening.

Key Features

• Solid red oak hardwood, not veneered or engineered
• S4S — surfaced on all four sides for uniform thickness, width and smooth faces
• Open, pronounced grain that takes stain and clear finishes evenly
• Dense enough to hold fasteners and machined joinery such as dados and mortises
• Machines, routers and sands cleanly for shaped edges and profiles
• Wide single-piece face suitable for shelving and panel glue-ups
• Sold as individual boards by the piece

Applications

• Cabinet and casework rails, stiles and face parts
• Hardwood shelving and closet build-outs
• Stair skirts, risers and tread or cap stock
• Window seats, benches and tabletop glue-ups
• Interior trim, jambs and built-up mouldings where a stain-grade face is required
• Furniture and millwork shop stock for resawing and profiling
