Our posts typically withstand 75 or more automotive impacts at 55 mph. With its pop-and-go design, FlexStake Glare Screen GS is literally a snap to install. When fully assembled, GS weighs only 13 lbs. per 12 foot section, so rails can be popped together off-site and hand carried to the barrier. FlexStake GS needs only four to six mounting studs per section, so labor and exposure to traffic are minimal. GS rails can be mounted on any rigid surface. GS's narrow-paddle, all-copolymer design is the most price competitive glare screen on the market.
