xTile Leveling System (302pcs) Material: PP + 430 Stainless Steel Suitable Spacer: 2mm-6mm Spacer Tile Thickness: 5mm-20mm Color: As picture shows Features: Durable, reusable. Easy to use for DIY. Keeps tiles balanced at the same horizontal level. Increases tile installation speed. Reduces installer fatigue/stress. Nearly frictionless flat surface. Reduces the need for grinding and polishing. Prevents tiles from moving while drying. How to Use: 1. Lay the first tile, leave more than 2mm (use with cross spacer). Close the tile. 2. Insert a T-shaped needle along the gap in the tile. 3. Then rotate 180 degrees, the T-shaped needle fixed to the bottom of the two tiles. 4. Adjust the caps by hand/with a special wrench until the two tiles are level. 5. About 4-6 hours after leveling, before the cement/glue is completely dry, rotate the anchors in the opposite direction, pull out the T-needle 180 and remove it. Notes: 1. Please allow 1-3cm error due to manual measurement. 2. Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you!
