Designed for the Hercules #8500 foam cutter available on Amazon and the Proxxon foam cutter. This fence will fit any foam cutter, as long as the slots in the bed are 5/16" wide. Made from 1/8" MDF, requires assembly with common wood glue or white glue. The small nail must be inserted from the bottom and then should be glued in place with a drop of medium CA glue or epoxy or something similar.
