Size:16 x 21 Inches The Martin Universal Design Pro-Draft Parallel Edge Board is both lightweight and portable with an anti-warp aluminum body straightedge but features a nonporous wood grain laminate drawing surface. The straightedge easily secures into position with two locking knobs and two (2) easy-fold legs provide an angle when needed. Two deeply ribbed strips on the back side allow the unit to be positioned over the table edge to bring the surface into the user's lap and rubber feet add stability while preventing movement. A comfortable handle is included for easy transport to class, workshops and even jobsites.
