As always, the best designs are the simplest. The Hall’s rainsaver guttering kit is easy to fit, with great customer support when needed. The instructions are clear and concise. I would add that the first instruction should be to offer up the brackets to the shed roof first, adjusting them so that they are a slight push fit on the roof structure. Remove them then assemble them to the guttering. This makes it easier when positioning the guttering onto the roof. Great product.
