This sign uses a 1/16" thick clear matte cover plate with subsurface background color laminated on to a 1/8" thick rigid acrylic backplate. A 1/32" cavity is created between the two layers of acrylic thus allowing space for a removable message insert to slide in. Signs are furnished in 16 standard colors with square corners. Holders are furnished without copy and 1/16" foam tape is applied to backside as standard mounting. Holders and inserts may be ordered with subsurface silk-screened graphics or surface applied pressure sensitive letters. Sign holders may also be ordered with radius corners, metal frames and various mountings.
