A VerroLoc circular flange ring is a component used in joining circular ducting. The flange ring is designed to be a quicker method of installing ducting, saving you time and labor.
Each joint comprises of 2 flange rings and 1 closure ring and are supplied together. You have to loosen the nut or release the closure ring of the closure ring, dependent on closure ring selected, to separate the closure rings from the two flange rings. Push one flange ring onto one end of the duct, starting with one end of the break point in the flange ring and working around the duct until the flange ring is completely seated on the end of the duct. To ensure a good seal, when selecting a starting point, where possible position the break point of the flange ring a minimum of 100mm from the cut seam of the spirally wound ductwork. The flange rings are manufactured to high tolerances and are designed to be fitted without the need for cutting. On occasions however it may be necessary to cut back the flange ring to give the optimum fit. Once the flange ring is in the correct position the ring must be secured to the duct.
