#TheFencePros at Bekaert demonstrate the proper way to install a HN brace using our new Fence Bullet Pipe Brace kit. We offer these kits in two pipe sizes (pipes not included):2 3/8” and 2 7/8”. This kit is a time and labor saving piece, which installs in less than five minutes after post driving. Braces are the most important element of your fence, the strength of your fence comes from the HN-brace.
