The gutter joint with its innovative design has a rubber sealing for a better and guaranteed waterproof installation. The long-lasting EPDM sealing is attached from the factory with two spots of glue that makes it stay in the right position when installing. The gutter joint creates a firm and durable installation with its perfect fit and snap on function to the half round gutter. Absolutely no need for silicon or other sealant. Silicon will dry and will not be tight against the surface of the gutter and there’s a risk it will leak.
