The Corner Brace Kit is used in conjunction with our Heavy Duty Deer Fencing Posts or Corner/Gate Post to make a very sturdy, internally supported corner. It is well suited as a corner support for a large enclosure using our Nylon Tension Cable. The Corner Brace Kit consists of 2, 9'-long x 1 3/8" diameter (black coated) braces that are buried 18" alongside the fence on the inside of the enclosed area. They then attach diagonally part way up the post (not included) with a band and cup (included).
