Shade sails are not hard to install. The fist thing that you want to do is look for the area that you want to install your sun sail over. Then you need to decide how you want to secure your shade sail. There may be trees around the area that you can attach to or even the side of a building. For this article we are going to talk about installing your shade sail to the side of a building and then onto two posts. First you need to make sure that the building side you are going to attach onto is safe and secure. Look for an area that you can install some eye bolts or even make a plate where you use all thread and bolts and actually drill into the building. The easiest way is to find some eye bolts or even a pad eye that can be easily screwed into the side of your house. Once you have decided what hardware you are going to use to attach to the building then you should probably go ahead and install.
The next important step that you are going to want to take is to install the posts. Your posts should be sturdy and stout. It is always recommended by professionals to use steel posts over wooden. However, if you have to use wooden posts just be sure to make sure that you use a large diameter. This holds especially true if you are going to install large sails. Once you have got your posts ready you need to start digging wholes where you are going to install. You should probably dig your holes at least four feet into the ground with a circumference of about 24 inches. However, you consult with an engineer who can tell you exactly what needs to be done in order to adhere to local codes such as wind ratings. The rule of thumb is that one third of your walk through height should go into the ground. If you have a 14 foot walk through you should bury about four and one half feet into the surface and then fill the ground with Portland cement.
