Running outlets are the one fitting in the steel system that do look and fit differently from their PVC counterparts.Unlike PVC, the steel outlet is actually installed once the gutter is in place, with a hole in the gutter being made prior to this point. Once the gutter has been clipped into place the outlet is then fixed in position using the locking tabs. This actually sounds more complicated than it is in practise.The installation of the running outlet is explained with images in our installation instructions.
