Flex-Stand is a 4-leg fold-up design made of durable lightweight aluminum with steel brackets. The legs fold down, lock in place, and telescope out for stability and to withstand windy conditions. The legs unlock with kick-release levers. The roll up sign is held in place by the cross-rib inserted into the mast bracket for a secure hold, and releases for removal. If hit by a vehicle, the signs and stand collapse upon impact. Manufactured to the guidelines of the Federal Highway Administration (FHWA) NCHRP-350.
