ESSVE plastic dowels are designed for fixing in concrete, brick and natural stone. Plastic dowels have a color marking for more convenient selection of the right size dowel. The dowels expand twice, except at the flange itself, which prevents cracks in fragile materials. Thanks to the double expansion and smooth surface, the dowels have a high tensile strength. Plastic dowels have wings that prevent rotation by screwing in screws. Dowels are made of polyethylene, operating temperature from -50° C to + 80° C.
