Line out

In order to determine a right angle, use an aspect ratio of 3: 4 5.

Note

Correct and precise layout is the best prerequisite for quick and neat installation.

Illustration for determining a right angle on the construction site by lacing with the 3:4:5 principle. A right-angled triangle with the side lengths 3000 mm, 4000 mm and 5000 mm is shown for exact angle determination during installation. This method is essential for a clean and fast installation.

Line out

Mark the desired corner point and then mark out a length of 3 m on the edge to which you want to determine the right angle. Then mark 4 m from the corner point in the approximate direction of the right angle. Now hold the zero point of the tape measures at the previously marked 3 m mark and measure 5 m from this point. The right angle from the corner point can be found at the intersection. This not only works with the dimensions 3, 4 and 5 m, but with any multiple or fraction of these dimensions. Only the ratio 3: 4 5 must be kept.
