Datum Line - How to measure your fixing point heights - Custom Made Shade Sails

How to measure your fixing point heights for custom-made shade sails. 

Create a Datum line for sloped or uneven land. You can simply use a string line to create a point of reference for your fixing point variations.

This will help achieve accurately fixing point dimensions for your custom-made shade sail.

Any height above the Datum line is labeled + and any height below the Datum line is labeled -.

This information is entered in our shade sail custom-made order forms in Box C.

All our custom-made shade sails are made in Australia with quality materials.
