The Checkers™ 4 ft Alley Bump Speed Bump, model GNRS2431YB was developed specifically to address speeding and cut-through traffic in city alleyways, slowing cars to approximately 1-5 MPH. Constructed from 100% recycled tires, the flexible design conforms to the contour of virtually any road surface. Pre-drilled holes make it simple to install on both asphalt and concrete. Applicable hardware is available for concrete or asphalt installations.
Designed to withstand extreme weather and stress, moisture, oil, temperature variations, and ultraviolet light, the Alley Bump will not chip, crack, fade, crumble, rot or deteriorate. A channeled bottom helps facilitate drainage as well as cover cabling or piping.
