    Clear Machinable Cast Acrylic Rods

    Widely used to make sight windows and light fixture lenses, these cast acrylic rods and discs maintain clarity over time. The material is scratch resistant and stands up to outdoor use better than polycarbonate. It maintains clarity over time and won't weaken from exposure to UV, though the pigment in colored acrylic will fade over time when exposed to direct sunlight. Comparable to Lucite and Plexiglas® acrylic, cast acrylic is easier to machine than extruded acrylic.

    Clear Scratch- and UV-Resistant Acrylic Rods

    Use these scratch- and UV-resistant acrylic rods and discs for sight windows, meter faces, and signs. They’re made of extruded acrylic, which is less expensive than cast acrylic with nearly the same performance. They’ll stand up to outdoor use better than polycarbonate and maintain clarity over time.
