Makes superior router sub-bases, duplication patterns, and clear fixtures for your shop. We stock hefty 3/8" thick Acrylic and Polycarbonate materials in large 12" x 12" squares (± 3/16"). Both crystal clear materials are easily cut and drilled with regular shop tools. The Acrylic is 'stiffer' to resist any flexing from holding heavy items over a long period. The Polycarbonate (generic Lexan®) is shatter resistant.
