Furowell is a foundation pipe made of PE-HD, constructed in a composite manner, with an externally corrugated and internally smooth surface, in black color, halogen-free and flame-retardant. This foundation pipe is used for the installation of masts, posts, and poles of all kinds, such as street lighting masts, traffic signs, flagpoles, boundary posts, and foundations for playground equipment. The advantages include its lightweight nature as well as easier processing and handling compared to concrete pipes and foundations. A standard hole saw of 68 mm creates a precise connection opening for Kabuflex Type 63.
