Web650-2.2.7 Backplates (Standard and Retroreflective): Backplates may be constructed of either aluminum or polycarbonate. Minimum thickness for aluminum backplates is 0.060 inch and the minimum thickness for polycarbonate backplates is 0.120 inch. The required width of the top, bottom, and sides of backplates must measure between five to six inches.
