Do it once, do it Right! Edge Right is the ultimate No-Dig edging. Instead of cheap plastics it's comprised of heavy duty 14 gauge COR-TEN steel. Worried about damage from your weed eater? Don't be! Edge Right can take unlimited abuse. Edge Right develops a rust patina over time to give a handsome modern look. (It can be sealed too!) Uses COR-TEN steel in order to be more malleable for use on curves in your landscape. The COR-TEN weathering steel can last well over 100 years.
