Product Overview

McCain’s LED Blank-Out Signs are an excellent way to provide clearly visible information to motorists, even in direct sunlight, ideal for reinforcing traffic signals and minimizing undesirable motorist movements. Blank-out signs are a superior alternative to static warning and regulatory signs due to their increased visibility, creating a safer driving environment.

In addition, McCain’s Blank-Out Signs’ enclosures meet NEMA 3R standards.
