A very old system, probably the first. Made from good steel but unfortunately no fall adjustment or overflow gap at rear of gutter. We’re starting to notice this product is having ingress issues due to there being no escape for the water.
To date their hasn’t been a product to take care of such a huge range of building methods from using Rigs as a cover fascia for old timber fascia through to revamping the troublesome internal systems by converting to external and ALL fascia systems in-between.
