How to install bracing for a carport
Measure the carport
Stand on the ladder and with help from someone else, measure the distance from one corner of the carport to the one diagonally opposite it. Repeat this for the other corners. If the distances are the same, your carport is square. To keep it square, nail a long piece of timber from the top of the post at the front of the carport to the bottom of the post diagonally opposite it. This timber will act as a brace.
