The E-SPF Position Marking Square is a Japanese square specifically designed for 1x4 and 2x4 lumber. It allows for quick and accurate marking of cuts, alignments, and screw positions.

Thanks to its integrated marking holes, it's easy to position screws regularly and neatly without having to measure each time. Compact, lightweight, and practical, this square is ideal for DIY projects, furniture, shelves, and light framing work.
