Bracket-mounted gutter systems are often difficult and time consuming to install and align, and special tools are required. However, the RHEINZINK- snap-lock bracket mounting system consists of a C-profile bracket mounting rail which fastens easily onto the fascia or roof edge. Gutter brackets are snapped into place easily and securely, and spaced along the mounting rail to suit loading conditions. The half-round 5" or 6" RHEINZINK gutter is then snapped into place with a click.
For sizing of gutters and downspouts please refer to the SMACNA (Sheet Metal Air Conditioning National Association) "Architectural Sheet Metal Manual"
