Wear-resistant, recyclable. Easy to use in DIY operation. Balance tiles in the same horizontal position. Improve the installation speed of tile. Reduce the fatigue and pressure on installers. Provides a nearly crack-free, flat surface. Reduces the need for grinding and polishing. Prevents tiles from moving during solidification. Instructions: Lay the first tile, leaving a thickness of more than 2mm (use spacers). Place adjacent tiles close together. Insert the T-pin into the gap between the tiles. Rotate it 180 degrees to secure the T-pin underneath the two tiles. Use a hand or special wrench to adjust until both tiles are level. Approximately 5–6 hours after leveling, and before the cement or adhesive is completely dry, rotate the cap in the reverse direction and remove the 180-degree T-pin.
