Here's how it works: Downpipe system DN 105/90/75/53
The downpipe system guides the rainwater from the gutter to the rainwater duct or into a drainage shaft. The individual sections are simply inserted while fitting the downpipe system. The soft transitions mean that the downpipe system is a real looker.
A "loose clamp" is used to guide the central section or the lower end of the downpipe. The eye bolt and washer are fitted between the straps of the pipe clamp to make this connection. This means that the pipe can move in the clamp and therefore compensate changes in length caused by temperature fluctuation.
