These drawing instruments are designed to be used along with a drafting table, but can be used with any studio desk. Rest the head of the T-square along the edge of your desk to keep it in place while you make the markings, lines, or guidelines you need. This transparent t-square is lightweight, graduated to 16ths, features imperial and metric markings, and has a hole for easy hanging storage.
Made from clear plastic. Markings up to 18 inches.
