Description Post Shields are 4 black individual shields that join together to cover and protect the lower 4″ of existing or new posts from string trimmers and other lawn care equipment. They install around posts od 5.5″x5.5″ in seconds with no tools necessary. 6×6 Post Shields are designed to fit the standard 6×6 labeled post. The standard 6×6 post measures 5.5″ x 5.5″. There are few exceptions so please measure your post to verify its size before purchasing. New treated posts are usually wet and swollen from the treatment process, but they will soon dry out and shrink to the 5.5″ x 5.5″ standard post size.
