  • Patent number: 6324783
    Abstract: The invention relates to a. molded plastic landscape edging strip with integrally moulded plastic spikes that can be severed on site for use in installation and also serve during storage and handling to stiffen the rear edge of the flexible plastic edging strip. Plastic spikes are less expensive to manufacture than conventionally used galvanized steel spikes, however, when integrally moulded with the plastic edging, the marginal increase in cost of the spikes is very low. The costs and time involved in manufacturing, inventory maintenance, handling, shipping and installation are reduced as a result of integrally moulding the spikes and edging together. The edging strip has an elongate vertical wall with bottom edge, front and rear faces, a horizontal footing extending rearwardly from the bottom edge with longitudinally spaced apart apertures and elongate plastic spikes severably joined to the rearward end of the footing.
