Opti Mauerstärken 18

OPTI Wall Strengtheners are ready-assembled connecting elements used as a clamping point between two formwork panels. They are made of plastic, have an inner diameter of 22 mm, an outer diameter of 26 mm and are 150 to 400 mm long. The wall strengtheners are also available in other lengths on request, e.g. push-fit versions up to 450 or 500 mm long. We recommend using PENTAFLEX® OPTI wall strengtheners in waterproofing components.
