The 24" x 18" format is especially popular for semi trucks, hotshot rigs, cargo vans, contractor vehicles, service fleets, towing companies, logistics companies, and commercial vehicles that need room for multiple certifications and operating authority details.

Important Magnet Information

Magnetic signs only stick to flat steel surfaces. They will not adhere to aluminum, fiberglass, plastic, carbon fiber, heavily curved panels, or surfaces containing body filler. Before ordering, measure your available flat door space and test with a household magnet if unsure.

For best performance and longevity, remove and clean your magnetic sign regularly. Clean both the vehicle surface and the back of the magnet after rain, road salt, dirt, or car washes to protect your finish and extend the life of your magnetic sign.
