Rainwater downspouts are always supplied with only one spout. It is impossible to connect another downspout without narrowing the throat. There are several methods, but the best one is to use crepe pliers. We also recommend the MAXI RET pliers, which are guided and have a creping depth of up to 52 mm. In this way you can install each downpipe quickly and effortlessly.
The tongs are used to narrow the throat of the storm drain.
