发明名称 Lightweight parking curb
摘要 A lightweight, hollow, plastic parking curb is set forth which includes a plurality of downwardly directed converging chambers to receive a pile or adhesive or combination of the two for affixing the curb to a parking surface. The pile may be provided on a fastener configured to be closely driven downwardly into the chamber. Alternatively, a bonding agent may be used to fill the chamber and base positioned recesses which communicate with the chambers.
