Developed from the need for a perfect plane between tiles that is often difficult to obtain due to imperfect screed coatings. Elements act at the same time as both a leveller and spacer without needing to use further cross or T spacers for the grout space. The adjustable pliers enable the correct pressure to be applied between the wedge and the element for the perfect alignment of the flooring. The universal wedge is recoverable and re-usable innumerable times. For tiles from 12 to 20mm thick.
