Storm Collar 125 mm

The storm collar is made of galvanized sheet steel and features a rain skirt to prevent water from entering the (spiral) pipe. The storm collar creates a watertight seal between the ventilation system and the roof duct. The storm collar is installed around the spiral pipe and rests on the roof duct/flanged sheet/lead flashing, ensuring a watertight seal around the duct, for example, the flashing (DD). We recommend sealing seams and cracks to prevent water ingress.

Installing a storm collar around a spiral pipe penetration will make it waterproof. The storm collar prevents water from entering the pipe penetration. This storm collar is suitable for pipes with a diameter of 125 mm. Sealing the collar is recommended.
