The SQ4 System is ideal for emergency applications resulting from loss of power or infrastructure. Whether it's a hurricane, tornado, earthquake or man-made disaster the SQ4 System provides safe reliable performance you can count on every time. A compact footprint, highly reflective delineation and unmatched reliability facilitates the placement of the SQ4 system in the center of the intersection. The battery pack provides 2 weeks of continuous operation with charging. The SQ4 System features fast efficient deployment with standard ball indications and optional turn arrows. The SQ4 System features deployment height options of 10 ft or 14 ft for maximum visibility (measured from the bottom of the green to he road surface).
