The Classic pass-through is used for both plain steel and bitumen roofings with Vilpe -pipes, -roof fans and aerial sleeves. Classic pass-through will be installed only after roof is completed. There is thick URITETTU rubber LISTA under the flange which makes the pass-through watertight. The set includes the screws and the sealing for underlay. Sealing mass has to be used when installing onto felt roof.
The basic colours of Vilpe pass-throughs are black, brown, green, grey, red and brick red.
