The Alvin PLB Lightweight Parallel Straightedge Board has all the qualities of a professional drawing board plus a lightweight build. Rubber-tipped legs provide a sturdy flat or angled surface, perfect for drawing or drafting. Bring your work closer with the non-slip rubber grip tracks that allow the board to extend past the edge of the table. Acrylic and aluminum straightedge has a rubber grip and smudge-free edge, and its metal brackets can accommodate thicknesses up to 3/16". Lock the blade during use to ensure straight lines. Carrying handle makes it easy to take your work with you. Fold the legs under for compact storage.
