Specifications: Material: High quality PP + stainless steel Scope of application: masonry Applicable Brick Gap: 2-6mm/0.08-0.24" Applicable Tile Thickness: 3-16mm/0.12-0.63" Size: 86*30*20mm/3.39*1.18*0.79" Weight: 13g Use Tips: Lay the first tile, leaving more than 2mm (with cross gaskets). Close to tile. Insert T-pins along the gap between tiles. Then rotate 180 degrees and the T-needle is stuck at the bottom of the two tiles. Adjust the lid with a hand/special wrench until the two tiles are on the same level. After leveling for about 5-6 hours, before the cement/adhesive is completely dried, rotate the lid in reverse and take out the 180 degree T needle until the word is removed. Avoid not removing the T-tile leveling system: 1. Ceramic tile gaskets are 2mm or more (cross gaskets are recommended) 2. When leveling, the cement or tile adhesives around T-type leveller must be cleaned. 3. Remove the T-type straightener about 5-6 hours after leveling before the tile binder or cement is completely dried. Products include: 10 x Leveler 1 x Wrench
