The Delta Level System 3929 Leveling System by Rubi is a professional leveling system specially designed for precise and efficient installation of ceramic tiles on floors and walls. This system uses wedges with thicknesses ranging from 3 to 12 mm in 0.5 mm increments, adapting flexibly to different tile thicknesses and installation requirements. Its design prevents the formation of the known “lippage” or unevenness between tiles, ensuring a uniform and aesthetic finish without imperfections. Additionally, the system minimizes tile movement during adhesive curing, allowing optimal fixation and significantly reducing the need for position adjustments during installation. It is recommended for use with medium and large formats, starting from 30x30 cm, facilitating work with tiles of various sizes and thicknesses up to 12, 15, or 20 mm, depending on the wedge model used. Sales are made in packs of 100 units (b-100 units), and assorted designs are shipped randomly based on available stock, adding a practical element to material management. This leveling system integrates as a reliable and simple technical solution for professionals seeking to improve precision and quality in the installation of ceramic floors and wall coverings, ensuring a uniform and durable result in every project.
