DURAFLEX-KA profiles are undrilled cover profiles made of aluminium for bridging wide joints when retrofitted to the floor covering. The cover profiles can be driven over by cars. The DURAFLEX KA expansion joint series also includes profiles pre-drilled on one side for screw installation and self-adhesive profiles. The narrow DURAFLEX KA profiles have a smooth surface, all other widths from 80 mm are equipped with grooved ribs for anti-slip.
