The Z/4 threshold profile for floors of the same height is one of MAPEI's Profix Thin systems for installing luxury vinyl tile (LVT) floating floors of thicknesses from 5/32" to 1/4" (4 to 6 mm). Like the C/4 threshold profile for floors of different heights and the S/4 end trim, Profix Thin Z/4 comes in a variety of anodized aluminum finishings and a wide selection of wood, stone or cement finishings to personalize your profile. C/4 also has a top profile coupled to a PVC base.
