R7-4-2 Questions

Is a No Idling sign required by law?

R7-4-2 Reflective Sheeting Options

Because the R7-4-2 is often posted along open curbs and travel lanes where drivers approach at speed, the T-11500 OmniCube - up to 60 percent brighter with a 12-year outdoor durability rating - is the safer choice when night visibility matters most, while the T-6500 High Intensity Prismatic delivers proven 10-year durability.

12 Year Outdoor Durability

The R7-4-2 puts a red legend on a white reflective background, and white returns more light than any other color under ASTM D4956, so nearly the entire face lights up under headlights. That is why stepping up to the T-11500 OmniCube produces such a visible change on this sign: you are brightening the color that already dominates the sign face.
