Whether you're in the Windy City or on California's windy coastline, you understand the complexities of stabilizing equipment with large surface areas such as a message board. For this reason, K&K's design team engineered a stronger and more stable trailer for message boards. Telescoping corner supports built into the trailer frame increase the overall footprint to reach an additional 4 feet front to back and side to side. Because of the telescoping design, the trailer retains the standard dimensions in transit, but on the job site the supports easily slide outward to create the expanded footprint.
