Sizing Your GUTTSA Kit
MEASURE THE GUTTER WIDTH AT DEEPEST END!
It is very important to make sure that you order the correct size kit for the job. Make sure that you calculate the width as the length of the two sides and the bottom. Similarly the length must allow for stop-ends, there is at least one, add 200mm for each stop-end. Then pick the required kit from the part number table.
Example: A leaking 400mm box gutter is 28.6 meters long with 110mm sides and has an end stop at both ends of the building. Which kit is required? . . . Using the diagram below we calculate the width as 620mm and the length as 29m.
Next we choose the 600mm by 50m kit, part 3600-050. We can allow the sides to run 10mm short along the sides (only at the outlet end) , you have to get the 50m kit as you therefore will have no joins in liner.
