Step 2 - Installing Your Fixing Points
It now is time to install your fixing points. As mention ed earlier, to achieve the desir ed effect of an architectural twist, fixing points should vary in height with diagonally opposite high and low points.
Once your posts are installed rigging components can be attached . Your Shade Sail will be attach ed to your posts or outer walls by eye bolts, eye nuts and wall plates. It is from these points that you will measure up for your shade sail from. Please ask your local dealer about the most appropriate fixings for your project.
Step 3 - Measuring Your Area
Measuring a Sail
When measuring a shade sail, it is important that you obtain as much information possible to give to the shade sail cutters. There are three types of measurements: Perimeter, Diagonal, and Height.
Installers must be careful to measure the Perimeter Measurements as close as possible, and they should measure to the fixing (posts, rafter brackets, wall plates, sail track) points after the hardware has been installed . The Diagonal Measurements, which also should be as accurate as possible, are the point to point measurements that are not representing sail edges, and are used to plot the corners and cross-reference the perimeter measurements.
The Height measurements are the actual or relative heights of the sail fixings. For Example, there may be three posts. They may be 3.04m, 3.55m and 3.78m respectively. So one might say that post 1 is level, post 2 is +500mm and post 3 is +700mm.
These measurements allow the sail cutter to take the difference in height of the posts into consideration when checking the measurements supplied by the installer. Height measurements need only be accurate within 100 - 150mm.
The illustration right shows a typical shade sail drawing we should receive from a shade installer.
Each point to point measurement available has been described .

The Heights of the posts have been added, relative to the lowest corner. |

In order to manufacture a quality shade sail, we require quite comprehensive measurements from our customers. In "triangulating" the sail construction, we automatically take into account the variances in fixing heights and necessary angles to best create your product. This includes diagonal measurements. It would not be possible to properly create your shade sail without these measurements, and we strongly advise that you spend the necessary time to obtain these measurements thoroughly and correctly.
Note: measurements must be made from fixing point to fixing point, i.e eye bolt to eye bolt.
Step 5 - Fitting and Tensioning Shade Sails
In order to ensure maximum longevity of your product it is imperative that you install you Shade Sail correctly. We recommend you follow these steps:
Once all mounting points have been installed and posts have been allowed to set for 48hrs, you can fit the sail.
With the wire rope fully slackened off, connect all direct connections first (connections without turnbuckles or lead wires), using a D-Shackle and a nylon sheave. Refer toFig 9 in the section 'sail corners'
Now using the aid of a rope ti ed to the triangle and loop ed through the eye-bolt, apply tension to the sail so all creases and folds are pulled out. You can now follow the instructions for turnbuckle connection.

Sail Corners
To prevent fatigue on the wire rope, and to give even wire tension, the sail corners should be assembled as shown Right.
The triangle rests on the top of the sheave, and they both fit snugly into the 8mm shackle.
The shackle pin slips through the triangle and the center of the sheave.
Be sure to install the shackle with the head of the pin facing upward to prevent the shackle-pin unwinding and falling out. |
