Mapei - Diaplas Aluminum "T-Shaped" Transition for Vinyl - Profiles and Trims

Their primary use is to create a joint cover between two floor surfaces of the same height already installed where expansion is expected. The curved end on each side of this profile has been designed to create a transition between the two floors if they are not perfectly the same height. This avoids creating an empty space between the trim and the floor. Often used to separate two rooms or to delimit two floors and specially created for vinyl floors based on its central leg which is very short allowing it to work with very thin surfaces.
