EXCELLENT MATERIAL: The tile leveling surface is made of pp plastic, the edges are smooth and do not hurt your hands, strong and durable, impact resistant and good toughness. STABLE CHASSIS: The bottom disc design can fit the tiles closely, accurate measurement and precise joint retention can improve the installation speed of ceramic tiles and reduce installer fatigue/pressure. NO DAMAGE TO CERAMIC TILES: The T cotter pins are made of thick stainless steel, which has high hardness and is not easy to damage ceramic tiles during the leveling process. SAVE TIME: Tighten directly by hand, with 2 special wrenches can reduce grinding and polishing time. Prevent tiles from moving during the curing process. It is easy to assemble without any tools, saving time and effort. VARIED USES: Adjust the floor or wall to maintain the fit and horizontal position between tiles to avoid unevenness . Features Suitable for tile thickness from 5mm to 15mm, suitable for tile gap ?2mm. Improves installation speed of the tileReduces the fatigue/stress of the installer; Ensures flatness between the tiles to avoid unevenness, with 2 special keys, Wear-resistant, reusable Prevents tiles from moving during curing;Reduces the need for grinding and polishing; Instructions 1.Place the first piece of ceramic with a joint thickness of at least 2 mm. and near the second ceramic; 2. Insert the T-pin along the crack, then rotate it 90 degrees, tighten the T-pin at the bottom of the two ceramics, and tighten the adjustment cover so that the two ceramics are at the same height. 3. Before the cement or tile adhesive has completely dried (usually no more than 6 hours), pull the adjustment cover in the opposite direction and turn the T-pin 90 degrees so that the T-pin turns zigzag parallel to the tile and remove the straightening machine; 4.Keep clean and dry for reuse.
