Gutter fall and support set-out

Turn gutter length, intended fall and maximum support spacing into end level and evenly spaced support points.

Measure along one continuous run between defined high and low points.
Use the system manufacturer or applicable local requirement.
Vertical offset from a repeatable level datum to the gutter reference point.
Use the smaller spacing required for the material, loads and local conditions.
Total fall over the run

60.00 mm

Low-end offset below datum

90.00 mm

Equal support intervals

20 intervals

Support points including both ends

21 supports

Equal spacing after rounding

0.600 m

A straight run with a constant fall and a support at each end. Corners, outlets, joints, snow guards, concentrated loads, fascia capacity, thermal movement and extra supports required by the selected system are excluded.
