Each of the screws and nuts in this garden sail set has a metric thread of 5mm . The 5mm diameter makes this fitting set perfect for small shade sails, but can also work well with other shades of different shapes and sizes . Each set consists of 2 turnbuckles, 2 carabiners, 4 buffer eyes/wall brackets, 16 plastic extensions and 16 screws.
Screw the wall brackets into the support structures to create attachment points for the turnbuckles and carabiners . This allows you to securely attach the wind rope and sun protection to the posts. Be sure to use the plastic extensions to hold the screws tightly, and then install the turnbuckles and adjust their length accordingly to achieve maximum tension and prevent the shade from sagging.
