Features: Wear-resistant, recyclable. Easy to use in DIY operation. Balance plates in the same horizontal position. Improve the speed of tile installation. Reduce fatigue/pressure on installers. There is hardly any creaking, flat surface. Reduces the need for grinding and polishing. Prevent the plates from moving during solidification. Specifications:Material: High Quality PP + Stainless Steel Application Scope: MasonrySuitable Brick Gap: 2-6mm/0.08-0.24"Suitable Tile Thickness: 3-16mm/0.12-0.63"Minimum Remaining Seam: 1.5mm/0.06"Size: 81*36*36mm/3.19*1.42*1.42"Use Tips:Lay the first tile, leaving more than 2mm (with cross seals). Close to attractions such as tiles. Insert the T-pins along the gap between the tiles. Then rotate 180 degrees and the T-needle will get stuck at the bottom of the two plates. Adjust the cover using a hand/special wrench until the two plates are at the same level. After leveling for about 5-6 hours, before the cement/glue is completely dried, turn the lid backwards and remove the 180 degree T needle until the word is removed. Do not avoid removing the T-shaped tile leveling system:1. Ceramic plate gaskets are 2mm or more (transverse gaskets are recommended)2. During leveling, clean the cementitious or tile adhesives around the T.3 level. Remove the T-type straightener about 5-6 hours after leveling before completely drying the binder or cement. Notes:1.
