Folding Frame Speed Trailer


The Wanco Folding Frame Radar-Speed Trailer features a large full-matrix display, oversize speed limit sign, and work zone sign. The display shows vehicle speed in bold 26-inch characters, warning motorists to slow down by flashing their excessive speed. Over 11 feet tall when deployed, the folding-frame design pivots the regulatory signs up to the vertical position when deployed, and down to horizontal for transport. The frame is held in place with a single support that ensures ease of use and prevents damage.
