Linex’s legendary super ruler uses a unique antislide principle, which makes it far more effective and easier to use than a traditional ruler. An integrated rubber strip prevents the ruler from sliding on the surface. The ruler can easily be repositioned by tilting it. Graduated in mm with a 0-30 cm scale on one side and a 15-0-15 cm scale on the other. With two bevels and one rubber strip. Material: glass-clear acrylic with green centre section.
