Aldon 4015-185 MoonSign Safety Sign

Day or night, the 18 in diameter MoonSign derail plate cannot be missed! It is over three times the area of the usual blue derail sign. White retro-reflective white facing and over-sized DERAIL lettering on both sides mean MoonSign can be seen at a greater distance night or day than the usual small blue derail sign. MoonSign sign plate fits any Aldon derail sign holder, hinged or portable.
