The Classic pass-through set is designed for the pass-through of standing seam roofings for VILPE P-type pipes and roof fans with a diameter of 110 - 160 mm as well as for aerial sleeves. The width of the Classic pass-through is 266 mm and the length 328 mm. The Classic pass-through set can be retrofitted as the pass-through of felt roofing.
There is a thick grooved rubber moulding under the flange of the Classic pass-throughs that makes the pass-through set waterproof. A seal for underlay and screws is included in the pass-through sets. Sealing compound must be used when the pass-through set is installed on a felt roof.
