Square Gutter Large Union - 135mm Black

These gutter unions are used to join lengths of Galecoand#039;s black square gutter together and come with a seal, clips and a strengthening insert. The clips push the gutter length onto the seal in order to create a water-tight joint.As with all PVC Gutter systems, we always recommend the use of our SL40 spray lubricant to protect the seals and increase their lifespan.
