The problem with installing conventional lawn edging is the necessity of digging a trench, laying it in, backfilling, etc. With this pound-in edging, installation is greatly simplified.
Each heavy-plastic interlocking piece measures 6 1/4" wide by 5 1/2" high. Using a rubber mallet, you hammer each piece into the ground, interlocking it with the previous piece. Installation couldn't be simpler, and it's easy to make curves and stagger the top level for going up hills (something you cannot do easily with conventional edging).
Enough to make approximately 20' of installed edging. Comes with four 90° corner connectors and four T-connectors. Instructions included.
