This interlocking border system looks and feels like real stone, without the weight. You will find endless design possibilities with this easy to assemble Rock Lock system! Suitable all year round, these hollow walls will not crack or chip and will actually extend your growing season by insulating the soil and plants. Not only can this system be used for landscaping or garden edging, two sets can be assembled together for a natural-looking raised bed. Combine with Rock Lock Curved Sections to create unique beds, or use Rock Lock End Rocks to complete straight runs, both sold separately.
