Hello! Are you in the market for a way to slow down traffic on/in your parking lot/property? Well, these 4 speed bumps may be for you! They measure approximately 71 INCHES LONG, 9 1/2 INCHES WIDE AND 1.75 INCHES TALL FROM BASE. They come with brand new screw anchors, screws and washers; so they simply need to be drilled into the surface of wherever the buyer prefers they be located. Ideal for parking lots, streets and driveways, all 4 are completely solid/heavy plastic; and have no cracks, splits etc. My asking price is $40 for each; or $140 for the set! REASONABLE OFFERS CONSIDERED. SERIOUS INQUIRES ONLY. DELIVERY UNAVAILABLE. CASH PAYMENTS ONLY.
