HammerEdge Pound-in-edging is strong, durable and easy-to-install. Pound-in Edging is a simple and effective way to finish off any landscape bed project. The “shark tooth” cutting design penetrates all soils, eliminating the need for trenches- it simply hammers into the ground and does not require edging stakes. Interlocking sections connect easily and provide ease of corner, arc or straight-edge installation for 18′ of coverage (16 pieces). Comes in black color.
