Product Review

This panel is made of corrugated polypropylene (Coroplast) material. The construction is very similar to the way heavy cardboard box material is made, but with polypropylene (plastic). It is 100% weatherproof, lightweight and a very tough ridged material. The panel comes with poly plastic letter tracks mounted on the panel, which is cut to fit a variety of a-frame sidewalk signs. The tracks are spaced to fit 4 1/4" or 4 3/8" letter kits. (Letter kits are sold separately)
