DDL Fiber cement wall sleeves
Wall sleeves made of asbestos-free fiber cement
DDL Fiber cement wall sleeves are designed to take in seal inserts for pipe and cable penetrations sealed against pressing water. The sleeve can either be set in concrete, walled in or be plastered into a wall penetration to be water-tight.
They are furnished with circumferential grooves and so compound very well with concrete. The dimensioning of the wall sleeves in diameter, wall thickness and their tolerances as well as the arrangement and layout of the grooves correspond to the works standards of one of the biggest German water suppliers.
