We have a supply of used curb stops, also known as wheel stops or parking blocks, made of steel reinforced concrete that are 8' long, 10" wide, 6 1/2" - 6 3/4" high, with 4" surfaces on the top and side planes. They weigh approximately 480 lbs. each, and there are two holes through the top for anchoring. They are for sale at $30 a piece picked up in Tipp City. We can load you either by picking them up from the side or end with a fork lift. Delivery and installation can also be arranged within a reasonable distance of Tipp City, Ohio for a negotiated rate.
