Use stretcher bars with square edges attached by t hreading through the fabric, attached with clamps, or attached by other positive mechanical means. Use brace bands and stretcher bar bands 1/8 inch by 1 inch, with 3/8 -inch diameter by 1 1/2 inches long, non-removable bolts. Do not use bent or damaged posts or rails. Place moisture -proof post tops. Position line -post tops to pass the top rail through the post tops. Place top rails in 20 -foot lengths, with couplings or expansion devices joining the lengths to form a continuous brace for each stretch of fence. Fasten top rails to end and corner posts by means of rail ends and brace bands. Use brace rails at end and corner posts, midway between the top and bottom rail, extending from the end or corner post to the adjacent line posts.
