Trunk Protectors are used at the base of trees to prevent damage from lawnmowers, edgers, and string trimmers. Their coiled shape allows them to expand with the growth of the tree. They are vented, which permits the tree to breathe and are notched at the base to accommodate root flare. The color helps them blend with the natural shade of the tree. Units fit up to a 4 in. caliper tree and multiple units may be used for larger trees.
