WindMaster & WindPro Curb Signs

The original WindMaster Curb Signs were first launched in the 1960's and are still the highest quality curb sign on the market capable of withstanding 75-mph winds without blowing over. Manufactured by MDI, it soon became well-established by launching significant innovations including the PosterGrip, the first spring-loaded, continuous-hinge, front-loading frame. The outdoor curb sign works on uneven terrain and the dual springs resists twisting in high wind gusts. WindPro has sign holder stands with wheels that roll by the sidewalk curb.
