Spin Doctor Tile Leveling System, 1/16" White Threaded Posts Large format tile is becoming increasingly popular on both residential and commercial job sites. Although tile is getting bigger, thicker, and becoming more difficult to install, the new RTC Products Spin Doctor Tile Lippage Control System is here to help. Attaining a flat and level tile floor or wall has never been so simple. Other systems require the use of unique tools or pliers, but the Spin Doctor tile leveling system can be installed by hand. The patented free-spinning leveling caps can be spun down the threaded post with just one hand; the minimal effort required is notably helpful when installing large format tile.
