The patented spring design incorporates an anti-rotational device and positive stops to prevent spring fatigue. The exclusive base, spring, and leg design reduces the need for sandbags and absorbs winds up to to 50 mph. Unlike steel, the Quadra Flex V is of with aluminum alloy that is more forgiving, spring-like and less likely to be bent or distorted when run over. Four steel L-shaped brackets reinforce crucial leg-to-base connection points, unlike stands where legs bolt directly to base. The unique rib mast assembly allows rapid assembly and compact storage.

The popular 36" double ply vinyl-coated mesh daytime signs are brilliant orange-red. The nighttime reflective sign actually switches from orange-red during the day to bright yellow when headlights shine on it. The Base and Mast kit includes one rib set and three flags. Order signs separately.
