Economy is more affordable
The orange telescopic ventilation duct is mainly composed of a soft edge of the horn mouth, a lifting ring, a rubber bone, a tail ring, and PP rope. The pipe body is made of PVC three-layer plastic canvas, with plastic bones wrapped in steel ropes as the skeleton, and colored plastic PVC mesh cloth as the pipe body. This combination gives this telescopic ventilation duct the advantage of waterproofing and flame retardancy, with strong sealing and no air leakage.
