Fabricate containers, tanks, and lenses for light fixtures with these scratch- and UV-resistant cast acrylic tubes. Cast acrylic, which is comparable to Lucite and Plexiglas® Acrylic, is easier to machine than extruded acrylic. This material stands up to outdoor use better than polycarbonate and maintains clarity over time.
