Weather collar for spiral duct Ø 180 mm

Installing a storm collar around a spiral duct will give it a watertight finish. The rain collar prevents water from entering the pipe lead-through. This weather collar is suitable for a 180 mm diameter pipe. Sealing of the collar is recommended.

Material
The spiral weather collars are manufactured to the highest standards. They are galvanised (Z275) according to the sendzimir process, making them durable in use and guaranteeing a long service life. This also makes them resistant to various weather conditions and less likely to rust.

Airtightness class
The rain collar meets the strict requirements for airtightness class D (ATC 2), according to standard EN12237.
